+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    Privacy Friendly Example App. The Android application demonstrate the design 
+    of a Privacy Friendly App. 
+    Copyright (C) 2016-2018 Karola Marky
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    Privacy Friendly Apps Copyright (C) 2016-2018 Karola Marky
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+#!/usr/bin/env python3
+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — Privacy Friendly 2048.
+
+Owns the game's CORE MATH: the input->output transform of a directional move.
+This lane is the SOLE OWNER of jump_kind="value": every test drives a TRIGGER
+(a DPAD move / restart / undo) and asserts a SPECIFIC numeric value or count that
+the ORIGINAL app produced — never a value computed from the source.
+
+The initial 2-tile seed and every spawned tile are RANDOM (a new tile is 2 with
+p=0.9, else 4; its cell is random), so NO absolute point total is hardcoded.
+Instead every assertion is a read-before / act / read-after DELTA or multiset
+relationship that is deterministic regardless of the RNG, and that a shell which
+does not implement 2048's merge rule cannot satisfy.
+
+GROUND TRUTH — all OBSERVED on the running original before writing (live probing):
+  * Fresh new game (4x4): EXACTLY 2 numeric tiles; points TextView == "0";
+    undoButton ABSENT.  (observed seed [2,4], points 0)
+  * Each non-empty tile is a Button whose text is its value ("2","4","8",...),
+    so every tile value + the score is read straight from the view tree.
+  * MERGE MATH — from GameActivity.handleSwipe*: on a move, `points += (merged
+    value)` for every pair that collapses; then addNumber() spawns ONE tile iff
+    the board changed. Confirmed live, e.g. [2,2,2,8,8] --UP--> [2,2,2,2,16],
+    points delta 16 (the 8+8 merge).
+  * MERGE CONSERVES THE TILE SUM: a+a -> 2a, so after any EFFECTIVE move
+    sum(tiles_after) - sum(tiles_before) is exactly the new tile's value, i.e.
+    it is in {2, 4}. Verified on many moves (sumdelta only ever 0/2/4).
+  * NEW-TILE-PER-MOVE: an effective move adds exactly one tile, so
+    merges = count_before + 1 - count_after.  merges==0 => a pure slide with
+    points delta 0; merges>=1 => points delta > 0 and EVEN. Verified.
+  * BLOCKED MOVE (direction already exhausted): NOTHING changes — the tile
+    multiset and points are identical before and after, and no tile spawns. A
+    blocked direction is FOUND by probing each of the four keys and reverting any
+    effective probe with undo (undo restores the exact pre-probe board+points —
+    verified [2,2,4,4]/pts 8 restored verbatim).
+  * record TextView == max(points, previous record), updated LIVE, and NEVER
+    decreases. record survives clear_data (it lives in the statistics file), so it
+    is asserted RELATIVE to the value read at game start, never as an absolute.
+  * restartButton: points -> "0", board re-seeded to EXACTLY 2 tiles, undo gone,
+    NO dialog. Verified (tiles [2,2] pts 0 after restart).
+  * undoButton: appears after the first effective move; tapping it returns points
+    to the exact pre-move value and the button disappears. Verified (4 -> 0).
+  * 5x5 mode (page 1 -> new game): the board grid has strictly MORE cells than
+    4x4 (Button nodes 29 vs 20), while a fresh 5x5 still seeds exactly 2 tiles.
+
+Failure messages use the taxonomy: setup_failed: / feature_missing: /
+behavior_wrong:.  Every game test crosses Main -> Game (depth=1), backed by the
+and_enter_game() helper (an and_enter*/and_reach* member) so the depth is real.
+
+VLM BUDGET (exactly 2, both fine-grained): the tile positions/counts and the
+score are all dump-readable, so VLM is spent only on genuinely RENDERED layout —
+the near-empty two-tile grid after restart (position) and the visibly larger 5x5
+grid vs 4x4 (size). Everything else stays a rule assertion.

+
+Owns EFFECT-BY-CONSEQUENCE on user DATA: multi-step (3+) sequences, multi-record
+integrity, and DATA persistence across process death. The "data" here is the saved
+game (board tiles + points), the per-mode statistics rows, and the continue-game
+availability that a saved game creates.
+
+Everything asserted was OBSERVED on the running original (recon.md + live probing).
+CONTRACTS CONFIRMED empirically on the device before writing:
+  * Game start: points TextView (id points) == "0"; board has EXACTLY 2 numeric
+    tiles; each non-empty tile is a Button whose text is its value; restartButton
+    present; undoButton ABSENT until the first effective move.
+  * A DPAD move that changes the board adds exactly one new tile and (on a merge)
+    adds the merged sum to points. A blocked move changes nothing.
+  * UNDO (undoButton): reverts the last move -> points returns to the pre-move
+    value, and the button disappears (once per move). NOTE: the tile MULTISET is
+    NOT a reliable undo invariant (the pre-move board already carried a random
+    new-tile from the prior move), so undo is asserted on POINTS equality, which
+    is deterministic. Confirmed: merge move points 0->4, undo -> points back to 0.
+  * RESTART (restartButton): points -> "0", board re-seeded to EXACTLY 2 tiles,
+    no dialog. Non-destructive to statistics/records.
+  * PERSISTENCE contract (confirmed all three arms):
+      - graceful back() to Main writes the save (onPause);
+      - kill AFTER back (force_stop_and_relaunch) -> continue ENABLED and restores
+        the EXACT points + tile multiset (48 / [2,4,4,16] restored verbatim);
+      - kill WITHOUT a prior back -> the save is skipped -> continue stays DISABLED
+        (from a clean clear_data() start). This is the discriminating arm: an
+        in-memory-only recreation cannot pass the survive-after-back test.
+  * STATS (StatsActivity, per-mode tab; suffix n: 1=4x4, 2=5x5): after playing 4x4
+    on a clean baseline, moves_All1/moves_L1 increase from 0, highest_number1 /
+    highest_score1 reflect play, undo_number1 increments after an undo; and the
+    5x5 tab (suffix 2) stays 0 -> multi-mode integrity. Blocked moves make exact
+    counts nondeterministic, so counts are asserted as >= the clean-baseline floor.
+
+Long-press: 2048 has NO long-press / context-menu feature (verified — tiles are not
+long-clickable), so none is invented. The overflow "More options" menu in
+StatsActivity is the one real context menu; opening it is safe (its single item is
+destructive, so it is never tapped).

+"""NAVIGATION lane — Privacy Friendly 2048.
+
+Sole owner of surface REACHABILITY and back-stack integrity: every jump is proven
+with and_reach() — the TARGET surface's discriminating element APPEARED *and* the
+SOURCE surface's element DISAPPEARED — so a screen that was already in the tree can
+never be mistaken for one that was navigated to. This lane carries the suite's
+depth>=2 chains (drawer -> Settings -> a preference dialog; Main -> Game -> back).
+
+Everything asserted here was OBSERVED on the running original (see recon.md + live
+probing). Key facts that drive the marker choices below:
+  * button_newGame carries text "START NEW GAME"  -> node_key "Button|START NEW GAME"
+  * button_continueGame carries text "CONTINUE GAME"
+  * restartButton has no text/desc -> node_key falls back to id suffix "restartButton"
+  * "START NEW GAME" is Main-only: it VANISHES on every drawer destination, so it is
+    the universal source marker. (view_pager is NOT — TutorialActivity has its own.)
+  * btn_prev is absent from the dump on page 0; btn_next is absent on the last page.
+  * Behind a Settings AlertDialog the settings list rows leave the dump, so the dialog
+    option ("Dark"/"Original") appearing while "Activate Animation" disappears is a
+    genuine depth-2 surface reach.

+"""STATE-CHANGE lane — Privacy Friendly 2048.
+
+Sole owner of CHECKED / SELECTED / ENABLED / FOCUSED transitions PAIRED WITH their
+app-authored consequence, of page-level state machines, of conditional
+enable/disable, and of SETTINGS / mode PERSISTENCE across a revisit or process
+death. A bare `checked==true` with no trigger and no consequence is never shipped:
+every case FLIPS or OBSERVES a state as the result of a user action, then asserts
+the consequence, then restores the baseline.
+
+Everything asserted was OBSERVED on the running original (recon.md + live probing):
+  * SettingsActivity is a ListView of preference rows (ids title / summary /
+    switch_widget). Two Switch prefs, BOTH default checked="true":
+    "Activate Animation" and "Activate Screen Lock". The correct Switch is the
+    switch_widget whose y is NEAREST the target title's y (never [0]).
+    Toggling flips checked and PERSISTS across a Settings revisit.
+  * "Select theme" row: tap -> AlertDialog System(checked)/Light/Dark. Selecting
+    Dark updates the row summary to "Dark" IN PLACE (activity stays SettingsActivity,
+    the whole UI repaints to a dark palette) and persists. Restore -> System.
+  * "Select Color Scheme" row: tap -> Default(checked)/Original. Selecting Original
+    updates the summary to "Original" and repaints the tile/preview palette
+    (Default = blue gradient, Original = classic orange/tan). Restore -> Default.
+  * CONTINUE-GAME conditional enable: on THIS emulator the 4x4 save survives
+    clear_data, but 5x5/6x6/7x7 have NO save, so button_continueGame is
+    enabled="false" there. Playing a 5x5 game and pressing BACK (graceful save)
+    flips it to enabled="true".
+  * undoButton (GameActivity) is ABSENT from the tree at game start and APPEARS
+    after the first EFFECTIVE move (a blocked move does NOT reveal it).
+  * restartButton resets points -> "0" (state-machine consequence, no dialog).
+  * Drawer item checked: "Main" checked="true" on MainActivity; after navigating
+    to Settings, "Settings" is checked="true" and "Main" checked="false".
+  * StatsActivity tabs (content-desc 4x4/5x5/6x6/7x7): tapping a tab selects it and
+    swaps the visible stat id set (*number1 -> *number2).
+
+LAUNCH QUIRK: restart_app() may RESUME GameActivity (the 4x4 save). _to_main()
+backs out until button_newGame is present, so every test starts from a real
+MainActivity regardless of the resumed task.

+"""TEXT / CONTENT lane — Privacy Friendly 2048.
+
+Sole owner of EXACT-STRING equality: the words an interaction PRODUCES (a score
+that changes as you play, a body paragraph an FAQ expansion reveals, a slide title
+that a NEXT tap swaps) and the app-unique static labels a recreation must get right
+(screen titles, section headers, preference titles, stat labels). Cedes the numeric
+DELTA to computation, the checked bit to states, reachability to navigation — this
+lane asserts only the RENDERED STRING.
+
+Every string below was READ off the running original before it was asserted (casing
+and spacing verified on-device — recon's approximations were re-derived):
+  * GameActivity header labels are exactly "Points" and "Record"; the `points`
+    TextView starts "0" and rises to a numeric string on a merge; on a clean DB the
+    `record` TextView also starts "0" and tracks max(points). A restart puts `points`
+    back to the exact string "0".
+  * MainActivity mode label is exactly "4x4"; btn_next swaps it to exactly "5x5".
+  * SettingsActivity title "Settings"; preference titles "Select theme",
+    "Activate Animation", "Activate Screen Lock", "Select Color Scheme"; the theme
+    summary reads "System" and the colour-scheme summary reads "Default" by default
+    (summaries share id `summary`, so they are located by their sibling title).
+  * StatsActivity labels: "Highest Number","Highest Score","Playing Time",
+    "Used Undo-Button","Total Amount of Swipes","Time per Swipe","Up","Down","Left",
+    "Right"; `time_played1` renders in the format "0.00 h" (ends " h"); tab TEXT is
+    UPPERCASE "4X4"/"5X5"/"6X6"/"7X7" (content-desc is the lowercase form).
+  * HelpActivity FAQ group titles are the exact 9 strings (id `listTitle`); tapping
+    the first row PRODUCES a body TextView (id `expandedListItem`) beginning
+    "The Privacy Friendly App 2048 is a privacy friendly version of the well-known
+    original game 2048."
+  * TutorialActivity slide 1 title "Welcome!" + body "In the following slides you
+    will learn how to play the Game 2048."; NEXT advances the title to
+    "Learn how to move the numbers!".
+  * AboutActivity labels "Version:" and "Authors:", author names
+    "Saskia Jacob and Julian Wadephul", link texts "SECUSO-Website" and "Github-Repo".
+    The version VALUE ("v 1.4.2") is source-derived and is NEVER asserted.
+
+Two VLM questions (this lane's ceiling), both genuinely NOT in the view tree:
+  * the undo/restart icon-only controls on the game toolbar (empty text + desc), and
+  * the drawn "2048" grid illustration on tutorial slide 1 (a Canvas/vector image).

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    Privacy Friendly Pedometer is an Android app that can count steps.
+    Copyright (C) 2016 Tobias Neidig

+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    Privacy Friendly Apps Copyright (C) 2016  Tobias Neidig
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+#!/usr/bin/env python3
+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION module — the app's core input -> output surface.
+
+The Privacy Friendly Pedometer's core computation is the "Correct steps" dialog:
+you enter a step count N and the summary card DERIVES and displays the day's
+step total, distance, and calories. This is a genuine value-owning surface, so
+this module is the primary owner of jump_kind="value".
+
+GROUND TRUTH (verified live on the running original, which is authoritative):
+  * stepCount is a DETERMINISTIC function of the entered value: set N -> the
+    summary card's stepCount TextView shows exactly str(N), every time, across
+    every value and every restart. This is the rock-solid input->output backbone.
+  * distanceCount is NOT reproducible as an exact point value: this emulator runs
+    a live step sensor whose accumulator drifts the internal distance baseline
+    between operations (the same N=200 produced 0.10 km at one moment and
+    -60.00 m minutes later). So this module NEVER asserts an exact distance number
+    it cannot reproduce. What IS deterministic about distance is its FORMATTING:
+      - distanceCount always renders with exactly two decimals ("-?\\d+\\.\\d{2}"),
+      - distanceTitle is "km" when the value is >= 100 m and "m" otherwise.
+    Those formatting invariants are asserted as values instead.
+  * The active-walking-mode popup radio (Walking/Running) has NO observable effect
+    on the displayed distance on this build, so no mode-multiplier value is claimed
+    (the original does not reproduce it -> asserting it would be a baseline_fail).
+  * The Day/Week/Month tab selects a computed PERIOD label:
+      Day -> "05. August" (single day), Week -> a range containing " - ",
+      Month -> "<Month> <YY>" (regex ^[A-Za-z]+ \\d{2}$). All deterministic.
+
+The "Correct steps" flow crosses a dialog surface, so those tests are depth>=1,
+backed by and_enter("correct_steps_dialog") inside the shared set_steps_clean()
+helper. Tab-switch tests are same-surface (depth 0) but still value-tier (the
+period value changed to a specific computed string).

+"""INTERACTION module — EFFECT-BY-CONSEQUENCE on user DATA for Privacy Friendly
+Pedometer.
+
+This lane owns CRUD lifecycles, 3+-step sequences where each action depends on
+the last, MULTI-RECORD integrity, DATA persistence across process death, and
+long-press / context (overflow) menus. Every test drives the app to the surface
+via the real user path, performs the action, then reads the CONSEQUENCE back out
+of a FRESH ui() and asserts it equals what was observed on the original app.
+
+Golden model (recon.md), all verified live on the original:
+  * Correct steps (MainActivity): summary card `periodMoreButton` (desc "Walking
+    modes") -> popup radio Walking/Running + item "Correct steps" -> dialog
+    (`alertTitle`="Correct steps", EditText `steps` PRE-FILLED with the current
+    count, `button1`=SAVE, `button2`=CANCEL). To set a KNOWN value the field must
+    be CLEARED first (MOVE_END then DEL x12) — typing APPENDS otherwise. SAVE
+    persists `stepCount` across an in-app navigation AND across process death.
+  * Walking modes (WalkingModesActivity, drawer->Settings->"Walking modes"):
+    RecyclerView `walking_modes_list`, seeded cards `name`="Walking(active)"
+    (0.50) and "Running" (0.70), FAB `add_walking_mode_btn` (desc "Add"), each
+    card overflow `card_menu` (desc "Options") -> context menu Set as active /
+    Learn / Edit / Delete. Add dialog: `input_name`, `step_length_edit`,
+    `button1`=SAVE. Adding accumulates across runs -> the add test is idempotent.
+  * Home summary popup radios: `title` TextView paired with a sibling `radio`
+    RadioButton (the checked bit lives on the RadioButton, not the title).
+  * Help (HelpActivity): ExpandableListView `generalExpandableListView`, group
+    headers `listTitle`; tapping "Overview" reveals a child text row (subtree
+    grows), tapping again collapses it.
+  * Training (TrainingOverviewActivity -> TrainingActivity): FAB `start_training`
+    -> live screen (`training_stop_button`="END TRAINING NOW"); stopping returns
+    to the overview and leaves a `card_training_session` row in
+    `training_overview_list`.
+
+SAFETY: tests mutate REAL device state. Destructive controls (Delete / Remove /
+Clear / swipe-to-delete of a walking mode) are NEVER tapped. `training_stop_button`
+("End training now") is SAFE and is used only to clean up a started session. Data
+is never wiped with clear_data() (it bounces to the launcher + re-prompts perms);
+restart_app() / force_stop_and_relaunch() are used instead.

+"""NAVIGATION module — surface REACHABILITY + back-stack integrity.
+
+Sole owner of jump_kind="reach" and of depth>=2 chains for Privacy Friendly
+Pedometer. Every jump is proven with and_reach(before, after, target, source):
+the TARGET surface's discriminating element APPEARED *and* the SOURCE surface's
+DISAPPEARED. Reaching a screen by relaunching is NOT navigation — every reach
+here goes drawer-item -> screen or FAB/list -> screen and is backed by an
+and_reach*/and_enter* call.
+
+Golden model (recon.md):
+  Home (MainActivity) = ViewPager of Day/Week/Month reports; drawer (opened via
+  the HAMBURGER, content-desc "Open navigation drawer") reaches Training,
+  Distance Measurement, Settings, Help, About.
+  Drawer items are CheckedTextView (design_menu_item_text); toolbar titles are
+  TextView — so "Training" as a drawer label vs the TrainingOverview title never
+  collide in a surface set. Home discriminator behind the open drawer = "Day".

+"""STATES module — widget STATE through before/after interaction.
+
+This module owns CHECKED and FOCUSED and every selected/enabled/mode transition
+PAIRED with the app-authored consequence, plus SETTINGS/mode persistence across
+process death. Nothing here is a bare flip: a `checked`/`selected` change is
+always paired with the observable effect the app authors around it (a range
+period label, a shown/hidden button, a radio that stays selected on reopen).
+
+GROUND TRUTH (verified live on the running original, which is authoritative):
+
+  * Pause/continue (E): toolbar Button `menu_pause_step_detection`
+    (content-desc "Pause step detection"). Tapping it REPLACES the node with
+    `menu_continue_step_detection` (desc "Continue step detection") and the
+    pause node DISAPPEARS. Tapping again reverts. The app-authored consequence
+    is this identity + content-desc flip (an icon button, so no `checked`).
+
+  * Tabs (A): the tab is a LinearLayout with content-desc "Day"/"Week"/"Month".
+    On launch "Day" has selected="true"; the others selected="false". Tapping
+    "Week" moves selected="true" to Week AND the two `period` labels change to a
+    range ("02. - 08. August", contains " - "). Month -> "<Month> <YY>"
+    (^[A-Za-z]+ \\d{2}$). So each tab test pairs the `selected` flip with the
+    computed period label consequence.
+
+  * Walking-mode popup (C): summary `periodMoreButton` (desc "Walking modes")
+    opens a ListView of rows; each row is a `title` TextView plus a sibling
+    RadioButton id `radio` (checkable=true). On open the "Walking" row's radio is
+    checked=true, "Running" false. Selecting "Running" closes the popup; reopening
+    shows the "Running" radio checked=true — the app-authored consequence. (The
+    device may carry extra seeded modes, so rows are matched by title text, never
+    by count.) RESET to Walking afterwards.
+
+  * Chart-type popup (D): chart `periodMoreButton` (desc "Options") opens a radio
+    list Steps(checked)/Distance/Calories. Selecting "Distance" and reopening
+    shows Distance checked=true, Steps false. RESET to Steps afterwards.
+
+  * Distance measurement (G): DistanceMeasurementActivity, Button `start_button`
+    ("START DISTANCE MEASUREMENT"). Tapping it REPLACES it with `stop_button`
+    ("STOP DISTANCE MEASUREMENT"); start disappears. A page-level state machine
+    (idle vs measuring). Tapping stop reverts. Asserted on the same Activity.
+    NOTE: starting a measurement makes the app request the LOCATION runtime
+    permission the first time; a left-over system dialog would otherwise leak onto
+    the next test, so every test enters through launch_clean(), which grants any
+    pending permission dialog through the GUI (never `pm grant`).
+
+  * Drawer (nav_view): each item is a CheckedTextView `design_menu_item_text`;
+    the item for the CURRENT screen is checked=true ("Pedometer" on Home), the
+    rest false. Beware: the toolbar title and the drawer header are ALSO the text
+    "Pedometer" but are plain TextViews — _drawer_item() matches the
+    CheckedTextView by resource-id suffix so the right node is read.
+
+  * Settings General (H): PreferencesActivity list of prefs. Each switch is a
+    `switch_widget` Switch whose row also has an `android:id/title` TextView; the
+    switch itself is clickable="false" AND SO IS EVERY OTHER NODE IN THE ROW (the
+    title, the widget_frame, the row LinearLayout) — nothing carries
+    clickable="true". Tapping the narrow title is therefore a no-op; the reliable
+    toggle is a tap on the FULL-WIDTH row CONTAINER's centre (the widest node
+    whose vertical bounds contain the title's y-centre and whose height is a
+    normal row height), which is what _tap_pref_row does (verified live: velocity
+    false->true->false via this tap). Defaults: "Show current velocity"=OFF,
+    "Use phone's step counting hardware"=OFF, "Permanent step counter"=ON,
+    "Keep processor awake"=ON, "Wake lock during training"=ON. Toggling
+    "Show current velocity" ON PERSISTS across force_stop_and_relaunch() back to
+    General — the signature persistence probe an in-memory recreation fails. Each
+    settings toggle test ENSURES the switch is OFF first (idempotent across repeat
+    runs even if a prior run left it ON), asserts the OFF->ON flip, then restores
+    OFF so the suite is order-free.
+
+    CONDITIONAL GUARD: "Use phone's step counting hardware" is a hardware-gated
+    preference — the app refuses to turn it ON when the device lacks a
+    step-counting sensor (PackageManager has neither
+    android.hardware.sensor.stepcounter nor ...stepdetector). On such a device the
+    row tap correctly leaves the switch OFF; on a sensor-equipped device it flips
+    to ON. The test asserts EITHER the OFF->ON flip OR (still OFF AND the feature
+    is provably absent) — both are the app's authored, observed behaviour, never a
+    bare existence check. The feature is read with `pm list features` (a device
+    query, not a state-seed).
+
+PAIRING title -> switch: switches are stacked tightly, so a title's switch is the
+`switch_widget` whose y-center is nearest the title's y-center (see _row_switch).
+Radio popups pair the same way via _radio_for_title.
+
+DEPTH: pause/tab/drawer flips are same-surface (depth 0). Popups are depth 1,
+backed by and_enter_popup(). Settings->General is depth 2, backed by
+and_reach_general(). Persistence relaunches, then re-navigates Settings->General
+(depth 2 again). jump_kind is "transition" for flips, "value" for the persistence
+assertion of one specific resulting state.

+"""TEXT module — exact CONTENT-string equality for Privacy Friendly Pedometer.
+
+Sole owner of exact-string equality: every test is TRIGGER (launch / navigate /
+tab-flip) -> OBSERVATION (an exact string, or a date-independent SHAPE, read out
+of a fresh ui()). A dead shell that clones the layout but renders no real strings
+FAILS here.
+
+What this lane does NOT assert (owner-priority, per recon.md):
+  * the computed pedometer VALUE (step count / distance / calorie number) —
+    computation's. We assert only FIXED unit labels ("Steps") and static
+    titles/summaries.
+  * reachability as the observation — navigation's. We still navigate to reach a
+    string (declaring honest depth via and_enter_* helpers) but the ASSERTION is
+    always the STRING on the surface, never "did the surface appear".
+  * a version/build/copyright value read from source — unfair to a recreation.
+    (The About "Version" LABEL is app-authored UI text and is asserted; the live
+    version NAME "3.1.2" was OBSERVED on the running original and is asserted as
+    such, not read from any source tree.)
+
+Runtime rules (recon.md): use restart_app() — NEVER clear_data() (it fires two
+permission dialogs and drops to the launcher). Open the drawer with the HAMBURGER
+(content-desc "Open navigation drawer"), never open_drawer() (its edge-swipe drops
+to the launcher). Match resource-ids by LAST segment via node_by_id().

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    Privacy Friendly App for playing Sudoku.

+Public License instead of this License.  But first, please read

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — Privacy Friendly Sudoku.
+
+CORE FUNCTION = the deterministic input->output surfaces that render in the view
+tree on the MAIN MENU (the GameActivity board/keypad is a custom canvas and is
+owned by the interaction lane; only 1 minimal VLM here touches the canvas).
+
+Everything asserted below was OBSERVED on the running original app, never derived
+from source. Ground-truth observations (fresh restart => MainActivity defaults):
+
+  section_label = "Sudoku 9x9"      difficultyText = "Moderate"
+  level_count   = "Levels available: 4"
+
+  GAME TYPE (section_label) — ordered list, CLAMPED at both ends (does NOT wrap):
+      Sudoku 6x6 < Sudoku 9x9 < Sudoku 12x12 < Sudoku 16x16
+      arrow_right advances toward 16x16 (clamps there); arrow_left toward 6x6.
+  DIFFICULTY (difficultyBar = a RatingBar) — tapping at an x-fraction of the bar
+      selects a rating: Easy / Moderate / Hard / Challenge.  circleButton (a
+      CheckBox) selects the separate "Custom" difficulty.
+  level_count = "Levels available: N" — a DERIVED count that changes with the
+      (type, difficulty) selection. Observed at 9x9: Easy=6, Moderate=4, Hard=3,
+      Challenge=9; at Moderate: 9x9=4, 12x12=5, 16x16=0. N depends on the
+      generator, so assert FORMAT + that it changes, never a fixed N.
+  Import dialog: one EditText echoes typed text verbatim; IMPORT / CANCEL buttons.

+"""INTERACTION lane — EFFECT-BY-CONSEQUENCE on user DATA for Privacy Friendly
+Sudoku. Sole owner of long-press and of DATA persistence across process death.
+
+Why almost every game assertion is a VLM check
+  GameActivity's board (SudokuFieldLayout), keypad (SudokuKeyboardLayout) and the
+  bottom special buttons (SudokuSpecialButtonLayout) are custom-drawn Canvas views,
+  and a 1-second timer animation keeps `uiautomator dump` from ever idling there,
+  so `ui()` returns a STALE tree (the menu). On that screen we therefore:
+    * confirm we are on it via get_current_activity() containing "GameActivity"
+      (dumpsys, not the tree),
+    * drive it with COORDINATE taps derived from get_screen_info() fractions
+      (never pixel literals — validated live: board x0~0.088/step_x~0.103,
+       y0~0.212/step_y~0.048; keypad row1 y~0.717 row2 y~0.790; specials y~0.871
+       at x 0.125/0.312/0.499/0.686/0.873 = Undo/Redo/Hint/Delete/Note),
+    * and verify the EFFECT with a screenshot + vlm_assert.
+  Every OTHER surface (menu, Import dialog, LoadGame) renders normally in the tree.
+
+The empty-cell problem, and how it is solved robustly
+  Each NEW GAME loads a DIFFERENT random puzzle, so a fixed cell may be a GIVEN
+  (bold, un-editable — selecting it shows a GREY highlight and ignores digit taps),
+  which made fixed-cell assertions flaky. Observed rendering:
+    * an EMPTY user cell, when selected, turns GREEN; typing a digit fills it.
+    * a GIVEN cell, when selected, turns GREY; typing does nothing.
+  So before typing we SCAN candidate cells and use a NON-recorded call_vlm to find
+  one the screenshot shows selected-GREEN-and-empty, then act on THAT cell and
+  phrase the assertion about "the currently selected green cell" (no fixed
+  coordinate baked into the question). Persistence, where the cell is no longer
+  selected after a resume, is asserted by the cell's 1-indexed (row, column).
+
+Observed ground truth these tests encode (all reproduced on the running original):
+  * tap empty cell -> tap digit N -> the cell renders N (green selection).
+  * Delete (trash) clears the selected user cell (a normal game action, allowed).
+  * enter -> delete -> enter a different digit: the cell holds the LAST digit.
+  * Undo reverts the last entry (cell empties, Redo lights up); Redo restores it.
+  * Note/pencil toggle -> digit taps write several small notes in one cell.
+  * selecting a filled cell whose value repeats highlights the peers GOLD.
+  * a started game is SAVED: after force_stop_and_relaunch(), CONTINUE GAME is
+    enabled and resuming shows the SAME board with the entered value (the killer
+    test an in-memory-only recreation cannot pass).
+  * long-press a LoadGame row -> a delete-confirm dialog appears; we assert it
+    appeared then dismiss with BACK WITHOUT confirming the delete.
+  * the Import dialog EditText echoes typed text and is empty again on reopen.
+
+Failure messages use the taxonomy: setup_failed: / feature_missing: / behavior_wrong:.

+"""NAVIGATION lane — surface REACHABILITY + back-stack integrity for Privacy
+Friendly Sudoku. Sole owner of jump_kind="reach" and of depth>=2 chains.
+
+Every jump is PROVEN with and_reach (target element APPEARED *and* source element
+DISAPPEARED) except the custom-Canvas GameActivity, whose view tree is stale to
+uiautomator — that surface is proven with get_current_activity() flipping to
+GameActivity plus a VLM check that the board actually rendered.
+
+Observed lifecycle quirks that shape these tests:
+  * GameActivity is singleTask; BACK from it returns to the ROOT MainActivity in
+    ONE press even when it was reached via LoadGameActivity (it does NOT unwind
+    back to LoadGame). The depth-2 back-stack test asserts that observed behavior.
+  * The main menu's button "CONTINUE GAME" contains the LoadGame title
+    "Continue Game" as a case-insensitive substring, so it cannot serve as a
+    disappeared-source. LoadGame's unique toolbar affordance "Navigate up" is used
+    as the source for the LoadGame->menu reverse jump instead.

+"""STATES lane — Privacy Friendly Sudoku.
+
+Owns checked/enabled/selected/focused transitions PAIRED with their app-authored
+consequence, page-level state machines, conditional enable/disable, and settings/
+mode persistence across process death.
+
+Ground truth (observed on the running original):
+  Settings switches (fresh restart): Note deletion=ON, Deactivate Timer=OFF,
+  Timer Reset=ON, Keep Screen On=ON, Dark Theme=OFF, Connected Fields=ON,
+  Same values=ON. "Deactivate Timer" ON disables the "Timer Reset" row
+  (disableDependentsState). Dark Theme persists across kill and darkens the app.
+  These switch values PERSIST, so every test that flips one restores it, and the
+  conditional test normalizes Deactivate Timer to OFF before asserting.
+  GameActivity is a custom canvas (uiautomator can't idle) -> game-screen state
+  transitions (selected green, peer highlight, same-value gold, note mode, undo
+  enabled-flip) are verified by VLM on screenshots. Difficulty stars: Easy=1,
+  Moderate=2, Challenge=4 filled blue stars.

+"""STRUCTURE lane — Privacy Friendly Sudoku.
+
+Owns exactly two things:
+  1. THE GATE: the app launches to MainActivity and its top-level surfaces exist
+     (main container, the menu buttons, the game-type/difficulty selectors, the
+     nav hamburger). These are jump_kind="none" and kept <=30% of the suite.
+  2. TREE-SHAPE DELTAS: an interaction that changes the tree's shape/size — the
+     nav drawer overlay adds a class of items, the Import dialog adds a new layer,
+     entering a sub-screen swaps the whole surface. Recorded as reach/transition
+     with an observed before->after, and reversed to assert it restores.
+
+Content strings belong to the text lane, computed values to computation, checked/
+enabled to states — this file only ever asserts SHAPE (node counts, surface-key
+sets, dialog appearance, activity flips).
+
+GameActivity is a custom Canvas with a 1s timer animation: uiautomator never
+reaches idle there and ui() returns a STALE main-menu tree. So on the game screen
+we NEVER assert on ui(); we confirm it via get_current_activity() (dumpsys, not the
+tree) and assert its shape with VLM screenshots.

+"""TEXT lane — CONTENT / OUTPUT strings for Privacy Friendly Sudoku.
+
+This lane owns exact-string equality of the strings an interaction PRODUCES or
+that a screen RENDERS: screen titles, section headers, stat-row labels, input
+prompts, the two main-menu button labels, the dynamic "Levels available: N"
+label, and the tutorial slide-content CHANGE driven by the NEXT tap.
+
+Every test is TRIGGER -> OBSERVATION: we navigate/tap/type, re-read a fresh
+ui(), and assert the specific string that appeared (never "the view exists").
+A dead shell that renders no strings FAILS every test here.
+
+VLM budget for this lane: 0 vlm_assert — every asserted string is readable from
+the uiautomator view tree, so this file is pure rule assertions.
+
+Package arrives ONLY as argv[1]; nothing here hardcodes it (or an APK path, a

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+                            Preamble
+
+The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+0. Definitions.
+
+"This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+1. Source Code.
+
+The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+The Corresponding Source for a work in source code form is that
+same work.
+
+2. Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+8. Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {one line to give the program's name and a brief idea of what it does.}
+    Copyright (C) {year}  {name of author}
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    {project}  Copyright (C) {year}  {fullname}
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — CORE FUNCTION input -> output for the PDF Converter app
+(swati4star.createpdf and any faithful recreation).
+
+This app has no calculator; its input->output surfaces are the *value dialogs*
+whose numeric input is written back into a visible card label. Each test drives
+the real user path (open the fragment, open the dialog, type a value, tap OK) and
+reads the resulting label out of a FRESH ui(). Every expected string was OBSERVED
+on the running original before authoring — never computed from the source. Where
+the source label format and the delegation brief disagreed, the LIVE observation
+wins (e.g. the Text-to-PDF font-size card renders "Font Size : N", NOT
+"Font Size (Default : N)").
+
+Ground truth confirmed live on the original:
+  * Images-to-PDF (needs >=1 selected image):
+      - Image compression dialog: type N -> card "Image compression : N %"
+      - Border width dialog:       type N -> card "Border width : N"
+      - Out-of-range (compression >100/<0, border >200/<0) -> R.string.invalid_entry
+        snackbar and the card label is UNCHANGED.
+  * Text-to-PDF (no file needed):
+      - Font size dialog: type N -> card "Font Size : N"  (observed live)
+  * Settings (drawer -> Settings; SharedPreferences-backed):
+      - "Image Compression default value : N %"  ;  "Font size default value : N"

+"""INTERACTION lane — EFFECT-BY-CONSEQUENCE on user DATA for the PDF Converter app
+(swati4star.createpdf and any faithful recreation).
+
+The backbone is the app's #1 feature: Images -> PDF creation via the system Photo
+Picker. Fixtures img_red/green/blue.png are pushed by the kit into /sdcard/Download
+and surface in the picker as MediaStore images. Every test drives the real user
+path, then reads the consequence out of a FRESH ui().
+
+Lane focus (validated on the running original before authoring):
+  * CRUD create: select image -> CREATE PDF -> name it -> OPEN PDF morph + file on disk
+  * multi-surface data integrity: the created PDF appears in View Files and History
+  * DATA persistence across process death (highest value; in-memory recreation fails)
+  * multi-record integrity: two uniquely-named PDFs both survive and are both listed
+  * multi-image selection count; View-Files row selection + count badge
+  * long-press context menu (sole owner): a row long-press opens "PDF Actions"

+"""NAVIGATION lane — surface REACHABILITY + back-stack integrity for "PDF Converter"
+(swati4star.createpdf). This lane is the SOLE owner of jump_kind="reach" and of the
+suite's depth>=2 chains.
+
+Every jump is proven with and_reach(before, after, target, source): the TARGET
+surface's discriminating element APPEARED *and* the SOURCE surface's element
+DISAPPEARED. and_reach_surface(node, target, source) does snapshot->tap->snapshot->
+verdict and counts one surface. Reaching a screen by relaunching is NOT navigation.
+
+The home grid RETAINS its scroll position across restart_app(), and a "Recently Used
+Features" row reflows the grid once features have been used, so every home entry is
+scrolled to the top first and card reaches key their SOURCE on a section header
+("Create new PDF" / "Enhance Created PDFs") that is co-visible with any card and
+always leaves the tree on a fragment jump — layout-independent.

+"""STATES lane — WIDGET STATE TRANSITIONS PAIRED WITH THEIR APP-AUTHORED CONSEQUENCE
+for the PDF Converter app (swati4star.createpdf and any faithful recreation).
+
+This lane owns `checked`, `enabled`/`disabled`, `selected` and `focused`, plus
+page-level enable/disable state machines and SETTINGS/mode PERSISTENCE across
+process death. Every test reads the state BEFORE out of a fresh ui(), drives the
+real user path, reads AFTER, asserts the flip AND the consequence the app authored
+(not a bare checked=true), then restores.
+
+Validated on the running original before authoring (expected values re-derived from
+what was OBSERVED live):
+  * CREATE PDF (pdfCreate) enabled=false BEFORE any image, enabled=true AFTER an
+    image is picked, with tvNoOfImages="1 image(s) selected." appearing.        [A]
+  * Set Page Size single-choice radios: selecting LETTER checks it, deselects the
+    DEFAULT, and — for THIS dialog — the choice is remembered on reopen.         [B]
+  * Set Image Scale Type single-choice radios: selecting Stretch checks it and
+    deselects Maintain in the SAME dialog (mutual exclusion is the app-authored
+    consequence; this dialog does NOT pre-check the choice on reopen unless
+    'Set as default' is used — observed live).                                   [B]
+  * Font Family radio: selecting HELVETICA checks it AND rewrites the card label
+    to "Font Family : HELVETICA" (observed — NOT the "(Default : ...)" form,
+    which is only the initial label).                                           [B]
+  * "Set as default" CheckBox in the value dialogs: unchecked -> checked.        [C]
+  * View Files row CheckBox: unchecked -> checked + a "1" selection count badge. [C]
+  * Settings theme / font-size / page-size default persist across a force-stop.  [D]
+  * Drawer is a single-choice CheckedTextView group; on launch exactly ONE item
+    is checked and it is "Home" (drawer navigation does NOT move the highlight in
+    this app — observed live).                                                   [E]
+  * Password Protect PDF dialog "Show password" toggle flips the field obscuring. [F]
+
+VLM budget: 11 assertions (theme recolor, selected-radio orange highlight, checkbox
+tick, disabled-grey/enabled-orange button pair, drawer Home pill) — the exact
+rendered properties an in-memory dead shell cannot fake.

+"""STRUCTURE-lane behavioral suite for the "PDF Converter" (image->PDF) app.
+
+Lane charter (see delegation): this file owns exactly two things —
+  1. THE GATE: the app launches, reaches the foreground, and its top-level home
+     surface exists (toolbar "PDF Converter" host + the feature-card grid). These
+     are jump_kind="none" existence anchors, kept a minority of the suite.
+  2. TREE-SHAPE DELTAS: a user interaction that changes the tree's SHAPE — the
+     nav drawer adding a whole class of CheckedTextView items, a dialog overlaying
+     a new window layer of RadioButtons, home->fragment replacing the grid with
+     fragment controls, scrolling revealing more cards. Recorded as
+     jump_kind="transition" and, where reversible, reversed to assert it restores.
+
+Everything is asserted on SHAPE (counts of a class, size of the surface key-set,
+container child counts, presence/absence of a discriminating container) — never
+on specific strings or values, which are ceded to the text/computation lanes.
+
+Only structure OBSERVED on the running original (recon dumps 01/02/03/04/22b/27
+and a live home screenshot) is tested here. Read-only kit; import, never edit.
+
+Run:  python3 test_android_structure.py <PACKAGE> <RESULTS_DIR>

+"""TEXT lane — CONTENT / OUTPUT text for "PDF Converter" (swati4star.createpdf).
+
+This lane owns EXACT-STRING equality: the app-authored strings a recreation must
+reproduce word-for-word — dynamic status lines a user interaction PRODUCES
+("1 image(s) selected."), app-unique static labels (enhancement-card labels,
+settings labels, the storage path), dialog TITLES an interaction opens, an
+input hint, and one genuinely opaque rendered core (the transient "PDF created!"
+snackbar, which never reaches the view tree -> VLM).
+
+Every string asserted here was OBSERVED live on the running original. The
+discriminating half, wherever possible, is the CHANGE: the string is ABSENT
+before the trigger and PRESENT after — a hardcoded label present at launch would
+pass on a dead shell, so those are anchored to a surface a navigation reaches.
+
+VLM budget for this lane: EXACTLY 2 (both tag="content"): the opaque success
+snackbar, and the Favourites empty-state as rendered.

+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — Amaze File Manager.
+
+A file manager has no arithmetic calculator, so the "computed values" here are the
+app's derived, input->output surfaces:
+  * the path-bar "N folders and M files" text (a LIVE count of directory contents),
+    and its DELTA when a folder/file is created or deleted;
+  * the Properties dialog's per-file / per-folder derived facts (Name, Location,
+    Size/items);
+  * Sort, a deterministic reordering of the row list (first-row VALUE flips with
+    ASCENDING vs DESCENDING).
+
+Every asserted value was OBSERVED on the original app during recon, never computed
+from the source or a constant. amaze_probe (a pushed fixture directory holding
+alpha/beta/gamma.txt) is the CONTROLLED input set for all count/sort/properties
+assertions, so the shared root's varying contents never leak in.

+"""INTERACTION lane — Amaze File Manager.
+
+Owns EFFECT-BY-CONSEQUENCE on user DATA: file/folder CRUD, 3+-step sequences,
+multi-record integrity, DATA persistence across process death, and (sole owner)
+long-press / context menus. Every case drives the running app to the surface via
+the real user path, performs the mutation, then reads the CONSEQUENCE back out of
+a FRESH ui() and asserts it against what was observed — never mere existence.
+
+Three app quirks the whole file respects (recon.md + live probing):
+  * LeakCanary hijacks the launcher, so a `monkey` launch lands on the system
+    launcher ~40-67% of the time. and_enter_amaze() RELAUNCHES (restart_app) up to
+    12x until get_current_activity() contains "MainActivity", then polls the dump
+    until the browser's `fullpath` has actually rendered (the first post-launch
+    dump is often empty). RELAUNCH is never a jump — it does not back a depth claim.
+  * The app persists the last-opened directory across process death, so after a
+    relaunch it may NOT be at root. reset_home() taps the Home toolbar button until
+    the browser shows /storage/emulated/0.
+  * The "New File" dialog PRE-FILLS its input with ".txt"; the "New Folder" dialog
+    starts empty. create_file() therefore clears the field before typing, so the
+    name is exactly what we assert (verified live: a raw type_text produced the
+    invalid ".txtAmzF_..." and no file was created).
+
+SAFETY: this lane creates and deletes DATA. Every created item has a unique
+marker name (AmzTest_<test>_<ms>), so reruns never collide and a stray row can
+never match pre-existing content. We delete ONLY items we just created, by driving
+the GUI (long-press -> CAB Delete -> confirm the "Delete items permanently?"
+positive button, which we accept ONLY for our own Amz* items). The fixture folder
+amaze_probe (alpha/beta/gamma.txt) and shared system folders are never mutated;
+copy is non-destructive and leaves the original in place (verified).

+"""NAVIGATION lane — Amaze File Manager.
+
+Owns surface REACHABILITY and BACK-stack integrity: every case proves a real
+surface jump with and_reach (the TARGET surface's discriminating element APPEARED
+and, for full-screen swaps, the SOURCE surface's element DISAPPEARED), and the
+back-stack cases unwind a 2+-hop chain one pop at a time.
+
+Three app quirks the whole file must respect (see recon.md + live probing):
+  * LeakCanary hijacks the launcher and a `monkey` launch sometimes stalls on the
+    system launcher, so and_enter_amaze() retries restart_app() AND then polls the
+    dump until the file browser's `fullpath` has actually rendered (an empty first
+    dump after launch is common). This is a RELAUNCH, never a jump.
+  * The app persists the last-opened directory across process death -> reset_home()
+    taps the Home button until the browser shows /storage/emulated/0.
+  * When the drawer is OPEN the main file list stays in the tree BEHIND it, so a
+    plain find_node(text=...) for a folder name matches the list row (x~189), not
+    the drawer bookmark (x~42). drawer_item() selects the drawer row by its
+    `design_menu_item_text` id so taps land on the intended bookmark.
+
+Overlay surfaces (drawer, search bar, context menu, dialogs) render ON TOP of the
+file list, so the list's elements stay in the dump; those reaches assert only the
+target's appearance (source=None). Full-screen swaps (folder navigation, FTP,
+Settings, Appearance, About) genuinely replace the source, so those name a source
+that must disappear. and_reach matches SUBSTRINGS, so a source is only named when
+it is NOT a substring of any target key (a child path contains its parent path, so
+folder-descent reaches use source=None). Every source/target was verified live.

+"""STRUCTURE lane — Amaze File Manager.
+
+This module owns exactly two things:
+  1. The GATE: the app launches into MainActivity with its top-level browser
+     surfaces present (listView + toolbar host + path bar).  jump_kind="none",
+     kept to a single cluster (well under the 30% ceiling).
+  2. Tree-SHAPE deltas: an interaction that changes the view-tree's SHAPE — the
+     FAB adds a class of menu nodes, the overflow adds a popup subtree, a
+     long-press adds the action_mode_bar layer, grid<->list flips the column
+     count, the drawer adds design_navigation_view, entering a folder changes
+     the row set, an empty folder swaps listView rows for the nofilelayout
+     subtree, and a dialog adds an md_root layer.  Each is recorded as
+     jump_kind="transition" and REVERSED to assert it restores.
+
+Content/state/focus/reachability are CEDED to the other lanes — we count and
+compare tree SHAPE only, never specific text values or checked states.

+This lane owns CONTENT / OUTPUT text and is the SOLE owner of exact-string
+equality:
+
+  * text an interaction PRODUCES (the FTP status line after START, the Properties
+    name that tracks the selected file, the "0 folders and 3 files" count),
+  * app-unique static strings a recreation must render correctly (screen titles,
+    section headers, button labels, an input hint, a content-desc),
+  * one genuinely OPAQUE text/graphic core (the Properties storage chart is a
+    Canvas ViewGroup that never carries text into the view tree) -> VLM.
+
+Every case is discriminated by the CHANGE: the string is ABSENT before the
+trigger and PRESENT after (a bare hardcoded label at launch would pass on a dead
+shell). Expected strings are only ever ones OBSERVED on the original; version
+numbers, free-space amounts, dates and device paths DRIFT and are matched by a

+GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (1) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (2) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.

+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to
+a network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not convey it at all.  For example, if you agree to terms that
+obligate you to collect a royalty for further conveying from those to
+whom you convey the Program, the only way you could satisfy both those
+terms and this License would be to refrain entirely from conveying the
+Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License, into a
+single combined work, and to convey the resulting work.  The terms of
+this License will continue to apply to the part which is the covered
+work, but the special requirements of the GNU Affero General Public
+License, section 13, concerning interaction through a network will
+apply to the combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+  OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+  THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+  IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+  ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+  THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+  USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+  DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+  PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+  EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+  SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+  above cannot be given local legal effect according to their terms,
+  reviewing courts shall apply local law that most closely approximates
+  an absolute waiver of all civil liability in connection with the
+  Program, unless a warranty or assumption of liability accompanies a
+  copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+  possible use to the public, the best way to achieve this is to make it
+  free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+  to attach them to the start of each source file to most effectively
+  state the exclusion of warranty; and each file should have at least
+  the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 2025 tom-murphy-development
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+  Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+  notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) 2025 tom-murphy-development
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+  The hypothetical commands `show w' and `show c' should show the appropriate
+  parts of the General Public License.  Of course, your program's commands
+  might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+  if any, to sign a "copyright disclaimer" for the program, if necessary.
+  For more information on this, and how to apply and follow the GNU GPL, see
+  <https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+  into proprietary programs.  If your program is a subroutine library, you
+  may consider it more useful to permit linking proprietary applications with
+  the library.  If this is what you want to do, use the GNU Lesser General
+  Public License instead of this License.  But first, please read
+  <https://www.gnu.org/licenses/why-not-lgpl.html>.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+#!/usr/bin/env python3
+"""COMPUTATION module — FastTimes (intermittent-fasting tracker).
+
+CORE FUNCTION here is the fasting TIMER and the derived AGGREGATES. This app has
+no calculator; its "input -> output" surface is:
+
+  * a goal cell tapped -> a live timer that either COUNTS DOWN ("Remaining",
+    timed goal) or COUNTS UP ("Elapsed Time", Open Fast); the timer VALUE is a
+    computed HH:MM:SS that changes over time.
+  * a timed goal -> a computed "Started" and "End Time" pair, End = Start + goal
+    duration (Test 1 Hour: End = Start + 1h; Test Timer 10s: Started == End).
+  * a timed goal reaching its target -> the value MODE flips: "Remaining"
+    -> "Total Time", the goal name -> "Goal Reached!", and the value then counts
+    UP; the "End Time" label -> "Goal".
+  * saving completed fasts -> integer AGGREGATES: the Dashboard "Fasts" count
+    (0 -> 1 -> 2), the Statistics "Total Fasts" ("1"/completed) and "Consistency"
+    ("100%"/goals met when the goal was met), the History "August Summary"
+    "Total Fasts", and a duration formatted \\d+h \\d+m.
+
+Every asserted number/relationship was OBSERVED on the running original (see the
+module docstring values above), never read from source or computed by hand. Wall-
+clock-dependent values are asserted as RELATIONSHIPS (decreasing / increasing /
++1h offset / count deltas) and PATTERNS, with tolerance — the debug Test Timer's
+~10s initial remaining is the only near-literal, and it carries a wide tolerance.
+
+CEDES to sibling lanes: whether a screen is reachable -> navigation; a control's
+checked/selected/enabled bit -> states; the mere EXISTENCE of a saved record (as
+opposed to its numeric aggregate) -> interaction; a non-computed content string
+-> text; the view-tree shape / drawn arcs -> structure (but the arc/chart that
+ENCODES a value visually is a legitimate VLM here).
+
+VLM budget for this lane = 4 (a value made visual, unreadable from the dump): the
+active-fast circular progress RING (partially filled proportional to elapsed), the
+FULL green ring at goal-reached, the statistics BAR CHART (bars of differing
+heights), and the statistics stat-card cluster showing the computed numbers.
+
+Compose renders as android.view.View / TextView with NO resource-ids, so every
+target and read-back key is a visible text / content-desc / bounds-located node.
+
+SAFETY: never taps "Delete" / "Delete Fast"; every exploratory tap is safe.

+"""INTERACTION module — FastTimes (intermittent-fasting tracker).
+
+Owns EFFECT-BY-CONSEQUENCE on user DATA: CRUD lifecycle (create a fast / a
+profile and read it back), multi-step sequences (3+ dependent actions), multi-
+record integrity (N records survive a mutation to one), long-press context menus
+(SOLE owner), and — the highest-value assertion — DATA persistence across process
+death. Every test drives the running original through the real user path, then
+reads the consequence out of a FRESH ui() and asserts it equals what was observed.
+
+CEDES to sibling lanes: a toggle's checked bit / settings persistence -> states;
+a computed value -> computation; the exact label wording -> text; whether a screen
+is reachable -> navigation; view-tree shape -> structure.
+
+Data model (verified live on the original):
+  * A completed fast is a HISTORY record: start the debug "Test Timer" goal cell
+    (a 10-second fast), wait ~11s for "Goal Reached!", tap "End Fast" -> the
+    "Fast Complete!" summary modal (5 clickable star Views + Save) -> Save. The
+    Dashboard "Fasts" count increments and the fast lands in History (Room DB) and
+    survives process death.
+  * A profile is created from Manage Profiles -> "Add Profile" FAB -> a dialog with
+    3 EditText (Profile Name / Description / Duration) + Save; the new card appears
+    in "Other Profiles". Save's clickable parent is disabled until a name is typed.
+  * Long-pressing a profile card reveals an "Edit | Favourite | Delete" button
+    group; "Favourite" moves the card into the "Favourite Fast" section.
+
+Compose renders as android.view.View / TextView with NO resource-ids, so every
+target and every read-back key is a visible text / content-desc / a clickable View
+located by bounds.
+
+VLM budget for this lane = 8 (visual DATA states unreadable from the dump): the
+summary-modal 4-filled-star row, the Daily-Details 4-green-star rating, the
+Edit-Fast 4-green-star rating, the long-press outlined card, the populated
+Favourite Fast card, the newly created profile card in the grid, the running
+active-fast ring after a process kill, and the multi-record history list.
+
+SAFETY: never taps "Delete" / "Delete Fast" (destructive); every exploratory tap
+goes through safe_tap(). The Add Profile dialog is Compose and dismisses on an
+outside-tap / BACK, so the kit's hide_keyboard() would close it — this module
+therefore taps the dialog's Save control DIRECTLY with the keyboard up (verified),
+and never sends a raw ESCAPE keyevent.

+"""NAVIGATION module — FastTimes (intermittent-fasting tracker).
+
+Owns surface REACHABILITY and back-stack integrity ONLY. Every jump is proven with
+and_reach(before, after, target, source): the TARGET surface's discriminating
+element APPEARED *and* the SOURCE surface's element DISAPPEARED — a flat dump read
+of an always-present element can never fake a reach. This lane is the sole owner of
+jump_kind="reach" and of the deep (depth>=2/>=3) chains; the other lanes stay
+shallow so real navigation depth is measured here.
+
+Nav graph (verified live on the original):
+  main = draggable two-pane Dashboard <-> History (swipe OR "Go to History"; BACK
+         or the Back arrow returns to Dashboard — History is NOT a nav route).
+  Dashboard -> Settings (gear), Manage Profiles (link), Statistics ("Go to
+              Statistics"). Settings -> Theme & Accent Color (Custom swatch).
+  History -> Daily Details (tap a day with a fast) -> Edit Fast dialog.
+  History -> History Info sheet ("i"). Active fast -> phase-detail sheet (chip).
+  Statistics -> History (top-right History icon).
+
+Compose renders as android.view.View / TextView with NO resource-ids, so every
+trigger and every discriminating key is a visible text or content-desc.
+
+VLM budget for this lane = 6 (transition end-states / toolbar affordances that are
+visual): the Statistics chart, the History month grid, the Theme&Accent swatch
+grid, the History-Info bottom sheet, the Daily-Details bottom sheet, and the
+Edit-Fast centered dialog card. Every other reach/back-stack case is pure rule.

+"""STATES module — FastTimes (intermittent-fasting tracker).
+
+This lane is the SOLE OWNER of CHECKED and FOCUS: every test is a before -> after
+STATE TRANSITION (checked / enabled / selected flip, page-state machine, or mode
+persistence) PAIRED WITH THE APP-AUTHORED CONSEQUENCE the flip produces. A bare
+checked flip with no observable consequence is worthless, so each transition names
+both halves.
+
+All states/consequences below were OBSERVED on the RUNNING original app:
+
+  * Settings SWITCHES render as android.view.View with checkable=true and a
+    checked=true/false bit; the row LABEL is a separate TextView on the same
+    y-band. "Show Fasting Phases"/"Show Floating Action Button"/"Use Expressive
+    Progress Indicator" default ON and flip true->false cleanly. (The two
+    Notification switches pop a permission dialog / OS grant, so they are NOT used
+    for a clean flip.) Turning "Show Floating Action Button" OFF removes the
+    dashboard FAB (desc="Add Fast") — a real authored consequence.
+  * Settings SWITCH state PERSISTS across process death (DataStore): flip one OFF,
+    force_stop + relaunch, it is still OFF.
+  * SEGMENTED toggles expose checked on the option View that CONTAINS the option
+    label's centre: Statistics "Weekly|Monthly" (Weekly checked by default;
+    tapping Monthly flips Weekly->false / Monthly->true AND flips the header
+    "This week"->"Last 30 days"), the "Trends" 3-way (Weekly default; "All Time"
+    flips to checked), and Settings "First Day of Week" Sun|Mon (Mon checked by
+    default; tapping Sun moves the checked bit).
+  * Add Profile dialog: Save's clickable parent View is enabled=false with an
+    empty name and flips to enabled=true once a name is typed; the "Set as
+    Favourite" CheckBox flips checked false->true.
+  * The dashboard FAB (desc="Add Fast") is a collapsed speed-dial: one tap reveals
+    child actions (desc="Start Open Fast" / "View History"), absent before.
+  * Statistics "All-time statistics" has an Expand chevron (desc="Expand"); tapping
+    it reveals new stat rows and flips the chevron to desc="Collapse".
+  * Theme & Accent Color screen: tapping an accent circle gives it a "Selected"
+    content-desc; its "Use Expressive Theme" switch flips checked.
+  * Theme selector Light|Dark|System exposes no checked bit — tapping "Dark"
+    recolours the app to a dark background (a genuinely VISUAL state -> VLM).
+
+CEDES: mere reachability of a screen -> navigation; a produced content STRING's
+exact wording -> text; a computed numeric value -> computation; CRUD/data
+persistence -> interaction; tree SHAPE / launch gate -> structure.
+
+Compose renders as View/TextView with NO resource-ids, so every target is located
+by visible text / content-desc / bounds.
+
+SAFETY: never taps Delete/Reset; exploratory taps route through is_safe/safe_tap.

+"""STRUCTURE module — FastTimes (intermittent-fasting tracker).
+
+Owns two things only:
+  (1) the GATE: the app launches into its Dashboard with the top-level surfaces
+      present (title, "Set your goal" card, the 2-col goal grid, the green FAB).
+  (2) tree-SHAPE deltas: an interaction changes the view tree's SHAPE — a class of
+      widget appears/vanishes, a dialog adds a window layer, a list populates. Each
+      delta is recorded as a before->after and then REVERSED to assert it restores.
+
+Content strings -> text lane; checked/selected -> states; reachability -> nav;
+values -> computation. Here we assert SHAPE and existence of surfaces, plus spatial
+layout via the VLM (the circular ring, the calendar grid, the expressive stat-card
+shapes — none of which reach the view tree).

+"""TEXT module — FastTimes (intermittent-fasting tracker).
+
+This lane owns CONTENT / OUTPUT strings that an INTERACTION PRODUCES — the exact
+words the app writes in response to a trigger — and is the sole owner of exact-
+string equality. Every test is TRIGGER -> OBSERVATION that a specific literal
+string appeared / changed on the destination surface. All strings asserted here
+were OBSERVED on the running ORIGINAL (see the probe transcript in the delegation
+notes), never read from source or computed.
+
+What this lane asserts (LABELS / COPY, never a computed number):
+  * empty-history status copy  "No recent fasts to show." (dynamic empty state)
+  * active-fast timer LABELS produced by starting a goal: "Remaining" (timed),
+    "Elapsed Time" + no "End Time" line (Open Fast)
+  * the goal-met COPY the app authors on the target-met transition:
+    "Goal Reached!" + label "Total Time"
+  * the fasting PHASE-chip name "Post-Absorptive State" (produced by an active
+    fast) and the phase-detail sheet's descriptive labels "Timing"/"Benefit"
+    (produced by tapping the chip — depth 1)
+  * the "Fast Complete!" summary copy: "Fast Complete!", "Rate your fast:",
+    "Started:", "Ended:", "Save" (produced by End Fast — depth 1)
+  * the Manage-Profiles empty-favourite HINT + section headers (depth 1)
+  * the Statistics header FLIP "This week" -> "Last 30 days" (Weekly->Monthly)
+    plus the empty-state subtitle and stat-card LABELS (depth 1)
+  * the History month header CHANGE "August 2026" -> previous month, produced by
+    the "Previous Month" control (depth 1; Next Month is disabled on the current
+    month, so the observable change is via Previous)
+  * the History-Info sheet copy "Understanding History" + legend (depth 2)
+  * the Daily-Details sheet TITLE "Details for <Month> <day>" produced by tapping
+    a day with data (depth 2)
+  * the Settings footer version string and section headers (depth 1)
+
+CEDES to sibling lanes: reachability itself -> navigation; the checked/selected
+bit -> states; the mere existence of a saved record -> interaction; any computed
+number (timer value, aggregate count, percentage) -> computation; the view-tree
+shape / drawn arcs -> structure. This lane cares ONLY about literal text content.
+
+Every string here is READABLE FROM THE DUMP (verified), so every assertion is a
+RULE assertion and this lane uses ZERO vlm_assert — its VLM ceiling is 2 but the
+brief is explicit that manufacturing a visual question for dump-readable text is
+wrong; text earns LOW VLM and 0 is the correct count here.
+
+Compose renders as android.view.View / TextView with NO resource-ids, so every
+target is located by visible text / content-desc.
+
+SAFETY: never taps "Delete" / "Delete Fast" / "Reset"; exploratory taps go
+through is_safe()/safe_tap(). Each test opens its own entry point.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — Idle Fantasy.
+
+Owns CORE FUNCTION input->output: the deterministic derived NUMBERS the app
+computes from its core idle loop and renders. This lane is the sole owner of
+jump_kind="value"; every assertion names the exact value OBSERVED live on the
+running original, never a value read from source or computed here.
+
+CEDES: whether a screen is reachable (navigation), a widget's selected/checked
+bit (states), the exact non-numeric label wording (text), the view-tree shape
+(structure), the DATA-mutation/persistence semantics of the loop (interaction).
+This file asserts the NUMBERS the loop produces, nothing else.
+
+Live-derived on the ORIGINAL (com.tristinbaker.idlefantasy), re-observed for this
+lane — every number below was READ OFF the running app, not trusted from prose:
+  * FRESH profile Home: Total Level = 23, Combat Level 1, Coins 0.
+  * Skills list: every level-1 skill shows '0 / 83 XP' (XpTable level-2 = 83).
+  * Skills -> Mining -> 'Choose Activity' sheet:
+      'Session: 60m', '~60 ores/session'
+      Rune Essence row: 'Lv. 1 • 15 XP/ore', projection '+900 XP → Level 8'
+      Copper Ore row:   'Lv. 1 • 18 XP/ore', projection '+1,080 XP → Level 9'
+  * Rune Essence 'Start Session' -> confirm dialog: title 'Rune Essence',
+    'Lv. 1 • 15 XP/ore'.
+  * Active-session HOME card projection: '+900 XP  →  Lv 8 (+7, 58%)'
+      (58% = (900-801)/(969-801) = 99/168; +7 = 8-1 levels gained).
+  * '[Debug] Finish Now' -> 'Collect 1 Session's Rewards' -> reward modal
+    'Mining Session Complete' / 'XP gained' / '+900 XP' / 'Loot' /
+    'Rune Essence ×60' (+ RANDOM gems). XP and the Rune-Essence ore count are
+    DETERMINISTIC; gem counts VARY and are NEVER asserted.
+  * After Close: Home Total Level = 30 (delta +7 vs the fresh 23); Skills ->
+    Mining now Level 8, '900 / 969 XP' (total XP / next-level threshold).
+
+The '~60 ores/session', '+900 XP', '×60', Level 8, '900 / 969', '0 / 83',
+Total-Level 23->30 numbers are the heart of the app's compute; they dominate here.
+
+The launch script pre-installs/pre-grants Clipper and ADB-Keyboard; this file
+never installs, grants, connects, or hardcodes a package/serial/coordinate.

+"""INTERACTION lane — Idle Fantasy.
+
+Owns EFFECT-BY-CONSEQUENCE on user DATA: the CORE LOOP as a 3+ step sequence, the
+persistent stat/inventory/skill mutations a completed session produces, DATA
+persistence across PROCESS DEATH (the app's headline WorkManager behaviour), and
+the long-press / context-menu surface. Every test drives a real user sequence and
+asserts the DATA it produced — a dead shell that renders the buttons but wires
+nothing must FAIL (session never starts, stats never change, log stays empty).
+
+CEDES: the numeric value itself (computation), whether a screen is reachable
+(navigation), a widget's checked/selected bit (states), the exact label wording
+(text), view-tree shape (structure).
+
+Live-derived on the original (re-observed, never trusted from prose):
+  * App LAUNCHES onto Skills, not Home; open_app_home() taps the Home tab, and
+    dismisses a leftover 'Session Results' modal a finished WorkManager session
+    can leave on top after a relaunch.
+  * The 'Choose Activity' sheet lists MULTIPLE activities each with its own 'Start
+    Session' button (Mining: Copper Ore / Rune Essence / Tin Ore). To start Rune
+    Essence, pick the 'Start Session' node whose y is closest to the 'Rune Essence'
+    label — document-order [0] is Copper Ore.
+  * Two DISTINCT collect paths, verified live:
+      - HOME card:  '[Debug] Finish Now' -> 'Collect 1 Session's Rewards' ->
+        modal 'Mining Session Complete' / 'XP gained' / '+900 XP' / 'Loot' /
+        'Rune Essence ×60' + random gems / 'Close'. THIS path populates Recent
+        Activity ('1. Mining / Rune Essence') AND the Inventory ('Rune Essence').
+      - SKILLS screen: '[Debug] Finish Now' -> 'Collect Results' -> modal
+        'Session Results' / 'XP gained' / '+900 XP' / 'Items collected'. This path
+        does NOT populate Recent Activity (stays 'No sessions completed yet.').
+    => the loop/stats/inventory/recent-activity tests all use the HOME-card path.
+  * Abandon (Home card): tap 'Abandon' -> confirm dialog 'Abandon Session?' /
+    'All progress from this session will be lost.' / 'Cancel' / 'Confirm'; tap
+    'Confirm' -> Home shows 'No Active Session'.
+  * Start-then-Cancel: the confirm dialog's 'Cancel' dismisses it and returns to
+    the (modal) Choose Activity sheet with NO active session; BACK then closes the
+    sheet and the Skills list shows the fresh Mining row '0 / 83 XP'.
+  * PERSISTENCE: start a session, force_stop_and_relaunch(), and the Skills screen
+    still shows 'Session Active' + plain 'Mining — Rune Essence' (the Home card
+    prefixes it with an emoji, so assert on Skills).
+  * Determinism on a FRESH profile: Mining/Rune Essence gives +900 XP, Total Level
+    23 -> 30, Mining Level 1 -> 8 ('900 / 969 XP'). Loot GEMS vary (Emerald/Ruby/
+    Diamond counts random) but XP/level do NOT — assert XP/level/presence, never
+    gem counts.

+"""NAVIGATION lane — Idle Fantasy.
+
+Owns surface REACHABILITY and BACK-STACK integrity: tapping a nav trigger (bottom
+tab, Home feature tile, toolbar gear, list row) lands on the intended surface —
+proven by the TARGET surface's discriminating element APPEARING *and* the SOURCE
+surface's DISAPPEARING (and_reach) — and BACK unwinds the stack hop by hop. Sole
+owner of jump_kind="reach" and of the suite's depth>=2 chains.
+
+Live-derived on the original (re-observed, never trusted from prose):
+  * The app LAUNCHES onto the Skills tab, not Home — every Home-anchored test must
+    tap the Home bottom tab first. open_app_home() bakes that in.
+  * A finished WorkManager session can leave a "Session Results" modal on top after
+    a relaunch; dismiss_modals() taps its Close so the entry point is clean.
+  * Bottom nav (Skills/Combat/Home/Quests/Profile) PERSISTS across every surface,
+    so the nav labels are useless as reach anchors. Discriminating anchors used:
+      Home     -> "Welcome back, Adventurer!"   (unique Home content)
+      Skills   -> "Expeditions"                 (Skills sub-tab, not a nav label)
+      Combat   -> "Combat Lvl 1"
+      Quests   -> "Resets at 6:00 AM"
+      Profile  -> "Unnamed Adventurer"
+      Shop     -> "Sell"          Inn -> "Daily Menu"    Guild -> "0 / 500 rep"
+      Church   -> "XP Blessings"  Slayer -> "Get New Task"  Carnival -> "Tickets: 0"
+      Builder  -> "Next Upgrade"  Settings -> "Theme" / "Font Size"
+  * Compose modal SHEETS REPLACE the list in the a11y tree: Skills->Mining opens
+    "Choose Activity" and "Expeditions" DISAPPEARS; Combat->Farm opens "Enter
+    Dungeon" and "Combat Lvl 1" DISAPPEARS. BACK/Cancel restores the source.
+  * Home->Guild Hall->Mining Guild is the app's only 2-level PUSH chain (bottom
+    tabs do not push): the guild DETAIL ("Daily Requests") appears and the guild
+    LIST ("Fishing Guild") disappears; BACK x2 unwinds detail -> list -> Home. The
+    guild list/detail SHARE a lazy Compose scaffold that non-deterministically
+    retains recycled rows of the OTHER surface, so neither "Daily Requests" nor
+    and_reach's "newly appeared" is a reliable per-hop signal. The stable proof
+    that BACK#1 popped exactly one level to the intermediate LIST is: the list-only
+    row 'Fishing Guild' is PRESENT and Home is NOT yet showing; BACK#2 then lands
+    Home ('Welcome back' appears, 'Fishing Guild' gone). Each BACK needs an explicit
+    settle("tap") — the 0.5s key settle catches a half-built frame.
+  * Profile chip rail -> Bestiary -> Bosses sub-tab is a 2-hop chain within Profile
+    ("King Black Dragon" appears, the Enemies row "Abyssal Leech" disappears).

+"""STATES lane — Idle Fantasy (offline idle RPG, Jetpack Compose + Room).
+
+Owns widget STATE through before/after interaction: checked / enabled / selected /
+focused TRANSITIONS paired with the app-authored CONSEQUENCE, page-level state
+machines, conditional enable/disable, and SETTINGS/mode PERSISTENCE across process
+death. Sole owner of CHECKED and of focus. Every test captures state BEFORE,
+performs the user-path trigger, captures state AFTER, and asserts BOTH the flip
+AND (where the app authors one) the consequence.
+
+Live-derived on the RUNNING original (re-observed, never trusted from prose):
+  * The app LAUNCHES onto the Skills tab, not Home — every Home-anchored test taps
+    the Home bottom tab first (open_home() bakes that in).
+  * Settings EXPOSES `checked` far more richly than expected:
+      - Recent Activity Log  -> a Compose Switch (checkable View), checked=true
+        default; tapping it flips true<->false IN-APP (stays on Settings) AND
+        gates the Home "Recent Activity" button (HomeScreen: showRecentActivityLog).
+      - Theme segmented [Dark/Light/System] -> each chip is a checkable View that
+        DOES expose `checked` (Dark=true default). Tapping Light sets Light=true,
+        Dark=false — a true rule transition, NOT visual-only.
+      - Profile Layout segmented [Rail/Tabs] -> checkable chips expose `checked`
+        (Rail=true default). Tapping Tabs sets Tabs=true, Rail=false, AND the
+        Profile screen relays out (section chip moves from a left rail x~100 to a
+        top tab row x~354) — a rule-observable consequence.
+  * Session Notifications is NOT an in-app checked toggle: tapping it DEEP-LINKS to
+    the OS notification-channel screen ("Navigate up" / "All Idle Fantasy
+    notifications" appear). So it is deliberately NOT used as a checked-flip rule
+    test — Recent Activity Log is the reliable in-app switch and covers the charter.
+    Its DEFAULT rendered thumb (right / gold) is still a fair VLM subject.
+  * Onboarding "Create Your Character" sheet: Confirm button's clickable View is
+    enabled=false while the name is blank and enabled=true once a non-blank name is
+    typed (source CharacterSetupSheet.kt: enabled = draftName.isNotBlank()). Gender
+    and Race chips are checkable Views that flip false->true on tap.
+  * Font Size dropdown is a state machine: tapping "Normal" OPENS a menu revealing
+    [Tiny/Small/Large/Huge] (closed -> open transition).
+  * Bottom-nav tabs and Quests sub-tabs do NOT expose selected/checked in the tree
+    (the gold highlight is visual only) -> those selection tests are VLM.
+  * PERSISTENCE: Recent Activity Log OFF and Theme=Light both SURVIVE
+    force_stop_and_relaunch() (Room / persisted settings). An in-memory recreation
+    fails these.
+
+Switches/chips are anonymous Compose Views (no text/id), so they are located by
+PROXIMITY to their visible label — never by a stale absolute position, which shifts
+after a flip. switch_for()/chip_for() re-derive the node from a FRESH dump each time.

+    "Create Your Character" bottom-sheet; Skip dismisses it and full Home renders.
+  * Compose modal SHEETS (Choose Activity, dungeon) REPLACE the scrollable list
+    in the a11y tree, so node count DROPS (98->27) — the honest primitive is
+    surface_changed() + the sheet's discriminating element appearing, not "grew".
+  * Home is android.view.View (Compose), never ViewGroup; bottom nav is a 5-item
+    row (Skills/Combat/Home/Quests/Profile) that persists across tab switches.
+  * The reward modal reached from the Skills screen is titled "Session Results"
+    with "XP gained" + item rows ("Items collected"), NOT the Home card's "Loot".

+"""TEXT lane — Idle Fantasy (offline idle RPG, Jetpack Compose + Room).
+
+Owns CONTENT / OUTPUT text and is the SOLE owner of exact-string equality: the
+strings a user ACTION PRODUCES (dynamic status labels, empty-state messages,
+descriptions, hints, difficulty verdicts, app-authored section/quest copy) and
+the opaque emoji glyphs that render on the session card / reward modal but never
+reach the view tree. Every test drives a real user path, then reads the resulting
+text out of a FRESH ui() and asserts the exact words are present — the
+discriminating half being the CHANGE: the string is ABSENT before the trigger and
+PRESENT after, so a dead shell that renders none of these FAILS.
+
+CEDES: the derived numeric value ('+900 XP' -> computation), a checked/selected
+bit (states), whether a screen is reachable (navigation), a widget's class
+(structure), the content of a record the loop created as DATA (interaction). This
+lane TOUCHES those surfaces only to reach a string; its ASSERTION is always the
+string content.
+
+Live-derived on the RUNNING original (re-observed on the emulator, never read from
+the source tree — the kit's lint_sources rejects source-derived answers):
+  * The app LAUNCHES onto the Skills tab, not Home — every Home-anchored test taps
+    the Home bottom tab first (open_app_home() bakes that in). A finished
+    WorkManager session can leave a reward/results modal on top after a relaunch;
+    dismiss_modals() clears it.
+  * Empty states (fresh profile), verbatim:
+      - Home session card: 'No Active Session' + 'Head to Skills or Combat to
+        start training.'
+      - Church:            'No active blessing — visit the Church to pray.'
+      - Slayer Master:     'No active task. Tap Get New Task.'
+      - Profile > Bonuses: 'No active XP bonuses'
+      - Recent Activity:   'No sessions completed yet.'
+  * Skill activity sheet (Skills -> Mining): title 'Choose Activity' + the Mining
+    description 'Extract valuable ores and gems from the earth.'. Tapping Rune
+    Essence's own 'Start Session' opens a confirm dialog titled 'Rune Essence' with
+    the description 'Raw magical stone used to craft all types of runes.'.
+  * Session status labels: starting Mining/Rune Essence shows 'Session Active';
+    on the SKILLS screen the label is the PLAIN 'Mining — Rune Essence' (the Home
+    card prefixes it with a ⛏️ emoji, which is why the plain-label rule assertion
+    reads it off Skills and the emoji is a VLM subject). '[Debug] Finish Now' turns
+    the Home card into 'Session Complete!'; Collect surfaces a reward modal whose
+    CONTENT strings are 'XP gained' + 'Loot' and a 'Rune Essence' loot row (the
+    '+900 XP' number is computation's, not asserted here).
+  * Combat dungeon list: the app-authored difficulty verdict for the low-level
+    Farm dungeon is 'You've got this' (higher dungeons read 'Likely to die').
+  * Quests: Daily sub-tab renders 'Resets at 6:00 AM' and an info line containing
+    'Each daily quest rewards coins'; Weekly sub-tab renders 'Resets Monday at
+    6am'.
+  * Settings: the Recent Activity Log row's description is 'Show Recent Activity
+    button in the home screen header'.
+  * A collected Mining session writes a Recent Activity entry mentioning 'Mining'
+    (empty 'No sessions completed yet.' before).

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+"""COMPUTATION lane — Urik Keyboard (com.urik.keyboard).
+
+This app is a soft-keyboard + settings app: there is NO calculator. Its
+deterministic input -> output surfaces are:
+  1. ListPreference dialogs: pick an option -> the row's `summary` becomes EXACTLY
+     that option's label (Suggestion Count, Key Size, Key Label Size, Cursor Speed,
+     Space Bar Size, Keyboard Layout, Long Press Punctuation, Long Press Duration).
+  2. Vibration Strength SeekBar: tap a position on the bar -> the `seekbar_value`
+     label shows the corresponding number (observed deterministic: far-left -> "6",
+     far-right -> "250", centre -> "128").
+  3. test_field EditText: type a string -> the field's `text` equals exactly that.
+
+Every expected value below was REPRODUCED LIVE on the original app (see _explore*).
+All tests are jump_kind="value" with a specific `expect`, depth=2 (Settings ->
+fragment -> [dialog]), and restore any mutated preference to keep the baseline clean.

+"""NAVIGATION lane — Urik Keyboard (com.urik.keyboard).
+
+Owns surface REACHABILITY + back-stack integrity: this lane is the sole owner of
+jump_kind="reach" and of the depth>=2 chains. Every forward jump is proven with
+and_reach(before, after, target, source): the TARGET surface's discriminating
+element APPEARED and the SOURCE surface's DISAPPEARED. A screen that was already
+in the tree was never reached. Every test opens its own entry point (the S0
+launcher, via open_launcher()) and navigates FORWARD from there; back-navigation
+is exercised as its own short forward-then-BACK test (nested cross-surface back()
+chains are flaky).
+
+Relaunching is only ever how a test re-establishes its S0 entry point — it is
+NEVER the mechanism that reaches a destination. The reach is always a forward tap
+proven by and_reach*, so restart lives in open_launcher()/open_settings(), one
+level below the reach call.
+
+Ground truth for every target/source string below was observed live on the
+original app before the assertion was written (see recon.md + recon_shots/).
+
+Two source-collision hazards were found live and encoded here:
+  * The Privacy screen contains the summary "Save keyboard settings and custom
+    key mappings...", so the substring "Keyboard Settings" does NOT vanish on the
+    S2->Privacy jump — the source for that jump is a distinctive list row instead.
+  * Several destination TOOLBAR titles equal their originating list-row text
+    (Open Source Licenses / Dictionary Data / Customize Keys / Reset to Defaults),
+    so those jumps assert a destination-only element (a content view id or a
+    unique button/message), never the colliding title.

+Every observed count below was confirmed on the running original app:
+  S0 launcher : FAB + 3 named Buttons (Enable/Open Settings/About) + CardView
+                preview card holding ~14 rendered key Buttons; container is
+                LinearLayout/FrameLayout (this app has NO ViewGroup / no Compose).
+  Settings    : RecyclerView of 8 preference rows; the 3 launcher buttons gone.
+  AutoCorrect : 5 Switch rows + a bottom test_field EditText.
+  Sugg. dialog: adds 3 CheckedTextView (a new AlertDialog window layer).
+  Features    : bottom-sheet subtree of 14 TextViews (7 tip title/desc pairs).
+  ThemePicker : RecyclerView of theme cards (6 FrameLayout content-desc "* theme"
+                visible; recycles, so we assert >3).
+  LayoutMapper: 40 rendered Buttons (number row + QWERTY rows + Reset All).
+  Typing      : 7 Switch rows and, after scrolling, a SeekBar (id seekbar).
+  Languages   : 12 CheckBox children (assert >=5).

+"""TEXT lane — Urik Keyboard (com.urik.keyboard).
+
+Owns CONTENT / OUTPUT text and exact-string equality: screen/toolbar titles that
+change with the surface you reach, preference SUMMARY strings a row shows, the
+summary an ACTION produces (Spell Check toggle -> "Spell check disabled"),
+static tip strings on the Features sheet, content-desc content on theme cards,
+and the About info block (a genuinely-rendered TextView -> the two VLM records).
+
+Every string below was OBSERVED live on the running ORIGINAL before it was
+asserted; nothing is copied from the source tree. Titles/summaries are matched
+by their EXACT dump text -- the uiautomator dump does NOT unescape '&', so the
+"Layout & Input" row carries literal text "Layout &amp; Input" and is matched
+that way (find_node_ci would fail on it).
+
+VLM budget: exactly 2 records, both on the About info block (a rendered text
+block) -- one asks the block is present, one asks the Copyright line is rendered
+in the observed colour. A separate RULE test asserts the exact About substrings.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>

+"""COMPUTATION lane — CORE FUNCTION input->output for TimePlanner.
+
+Owns jump_kind="value": apply a specific INPUT (Start/End times, a category, a
+task count) then assert the SPECIFIC computed OUTPUT string the RUNNING original
+produced. Every expected value here was OBSERVED live on the original app, never
+derived from source or from arithmetic — the app is the ground truth.
+
+The two computations this planner actually performs:
+  * Editor duration = End - Start, formatted "Xh Ym" (recomputed live as the
+    Material time picker changes End). Independent of the wall clock, so stable.
+  * Analytics category proportion: with a single categorized task the donut/legend
+    show that category at "100%" and every other at "0%"; the donut CENTER shows
+    the summed total time. Stable for a controlled single-task input.
+
+Wall-clock-dependent values (a running task's ELAPSED time, "today") are NEVER
+asserted — only schedule geometry (End-Start) and controlled proportions.

+"""STATES lane — CHECKED/SELECTED/ENABLED/FOCUSED transitions PAIRED WITH THEIR
+APP-AUTHORED CONSEQUENCE, plus SETTINGS/mode PERSISTENCE, for TimePlanner.
+
+Owns (sole owner of `checked` and `focused`):
+  * switch flips paired with a consequence (Statistics/Notifications switch ->
+    checked flips; Notifications OFF -> the reminder-gear button disappears),
+  * segmented-selector transitions marked by a moving "Selected" glyph
+    (Priority Standard/Medium/Max; Settings Theme Light/System/Dark; Calendar
+    icon behavior Pick-a-date/Set-to-today),
+  * real toggle switches (Dynamic colors, Secure screen) whose `checked` flips,
+  * the Home Compact/Expanded-view mode flip (label changes),
+  * the category bottom-sheet RadioButton `checked` moving between rows,
+  * SETTINGS PERSISTENCE across process death (Theme, Calendar behavior).
+
+Every test drives the app to the surface through the REAL user path, reads the
+state BEFORE from a fresh ui(), performs the tap, reads AFTER from a fresh ui(),
+and asserts the transition AND its consequence against what was OBSERVED on the
+running original. Each test owns its own entry point; the two persistence tests
+deliberately span a restart.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>

+"""INTERACTION lane — QR & Barcode Scanner.
+
+This lane owns EFFECT-BY-CONSEQUENCE on user DATA: a create/edit lands in the
+SQLite-backed History and can be READ BACK OUT of a fresh dump, multi-step
+chains where each action depends on the last, multi-record integrity, and —
+the highest-value probe — DATA PERSISTENCE across process death. An in-memory
+recreation that keeps a row only until force-stop cannot pass those.
+
+GROUND TRUTH — every path below was driven on the running original
+(com.example.barcodescanner, 2026-08-06) and its consequence read from a live
+uiautomator dump:
+
+  CREATE Text : Create tab -> button_text -> edit_text -> item_create_barcode
+                -> result BarcodeActivity: text_view_barcode_text = raw text,
+                   image_view_barcode, item_add_to_favorites, item_delete.
+  HISTORY row : item_barcode_history -> image_view_schema + text_view_date +
+                text_view_text (name or formattedText) + text_view_format
+                ("QR Code"). A created row appears here and SURVIVES
+                force-stop + relaunch (verified: "IXN-PROBE-123" persisted).
+  OPEN a row  : tap_text(nodes, "<row text>") -> BarcodeActivity (isCreated
+                FALSE): item_add_to_favorites ("Add to favorites"),
+                item_show_barcode_image ("View code"), item_delete,
+                button_search ("Search on the web"), button_edit_name.
+  VIEW CODE   : item_show_barcode_image -> BarcodeImageActivity:
+                image_view_barcode + text_view_barcode_text = same text +
+                item_increase_brightness; button_search is GONE (jump proof).
+  FAVORITE    : tap item_add_to_favorites -> content-desc STAYS "Add to
+                favorites" (only the star icon changes -> a real VLM question);
+                the reliable NON-visual consequence is the row now appearing
+                under the FAVORITES tab, absent for a non-favorited row.
+  WI-FI       : button_wifi -> edit_text_network_name -> item_create_barcode
+                -> result text WIFI:T:WPA;S:<name>;H:false;; ; history format
+                "QR Code" (verified "IXNWIFI777").
+  EDIT NAME   : button_edit_name -> dialog "Edit name" with
+                edit_text_barcode_name + OK/CANCEL -> text_view_barcode_name =
+                name, and the history row's text_view_text becomes the name.
+  CLEAR GUARD : History overflow "More options" -> "Clear history" -> dialog
+                "Delete history?" with CANCEL / DELETE. We tap CANCEL and prove
+                the data is intact. We NEVER tap DELETE.
+
+WHY WE NEVER clear_data(): it revokes the fresh emulator's camera grant and
+wedges the Scan launch surface behind a permission dialog for the rest of the
+run. Every test therefore uses restart_app() (force-stop + relaunch), which
+preserves permissions AND the SQLite history. Because history is never wiped,
+each test is SELF-RELATIVE: it uses a UNIQUE marker, asserts that marker ABSENT
+before the action and PRESENT after, so pre-existing rows and re-runs never
+contaminate a verdict.
+
+Long-press: this app has NO useful long-press (a history-row long-press does
+nothing per source), so this lane authors none — inventing one would fail on
+the original.

+"""NAVIGATION lane — QR & Barcode Scanner.
+
+This lane owns SURFACE REACHABILITY and BACK-STACK INTEGRITY: tapping a nav
+trigger (tab, list row, toolbar action) lands on the intended surface, and BACK
+unwinds the stack hop by hop. It is the SOLE owner of jump_kind="reach" and of
+the depth>=2 chains — the other lanes stay shallow so real depth is measured here.
+
+A reach is proven ONLY with and_reach(before, after, target, source): the TARGET
+surface's discriminating element APPEARED *and* the SOURCE surface's element
+DISAPPEARED. A screen that was in the dump all along was never "reached".
+
+Ground truth was observed on the running original (com.example.barcodescanner,
+2026-08-06). Every token/title/label below was seen in a live uiautomator dump.
+
+TOKEN-CHOICE LESSONS baked into this file (each cost a debugging round):
+  * and_reach does a SUBSTRING, set-difference match. A token present on BOTH
+    surfaces can never satisfy the appeared/disappeared test.
+      - The Create tab has a row labelled "Text" (TextView|Text), so the Text
+        INPUT screen cannot be reached by the token "Text". Every input screen is
+        instead discriminated by "EditText" — no chooser/list surface has one.
+      - The More-QR and Barcodes-all choosers each contain a "URL" row
+        (button_url), so button_url is NOT a valid SOURCE for reaching a chooser;
+        button_create_barcode (a Create-tab-only row) is.
+      - An EditText's HINT leaks into its text ("Phone" field -> key
+        EditText|Phone), so target the class token "EditText", never the hint.
+  * Toolbar OVERFLOW menu items surface in the dump as their TITLE TextView, e.g.
+    the "View code" action is TextView|View code and the View-code screen's
+    brightness action is TextView|Increase brightness. Those visible labels are
+    the reliable tokens; the item_* resource-ids sit on non-rendered menu nodes.
+  * scroll_into_view() brings the anchor row on screen but scrolls the FIRST rows
+    OFF, so a SOURCE token must be snapshotted BEFORE scrolling (Settings does).
+  * Input screens AUTO-FOCUS their EditText, so the soft keyboard is up and the
+    FIRST BACK only hides it — back-stack tests hide_keyboard() before and_back().
+
+  Surfaces & their discriminating tokens:
+    SCAN            scanner_view (Scan-only source); image_view_scan_from_file.
+    CREATE          button_text/url/wifi/.../show_all_qr_code/create_barcode.
+    Text input      EditText; title "Text".
+    Wi-Fi input     spinner_encryption + edit_text_network_name; title "Wi-Fi".
+    More QR codes   CreateQrCodeAllActivity, title "Create QR code"; button_otp.
+    Barcodes-all    CreateBarcodeAllActivity, title "Create barcode"; button_ean_13.
+    EAN-13 / Phone / Email input   EditText; titles "EAN-13"/"Phone"/"Email".
+    HISTORY         title "History"; tabs ALL/FAVORITES; recycler_view_history.
+    Barcode(opened) button_search ("Search on the web") + "View code" action;
+                    a created result has NEITHER — this proves a HISTORY open.
+    View code       BarcodeImageActivity; "Increase brightness" + image_view_barcode
+                    APPEAR, the row of Copy/Share buttons DISAPPEARS.
+    SETTINGS        title "Settings"; button_choose_theme (Settings-only).
+    Theme / Camera / Supported formats / Search engines   button_light_theme /
+                    button_back_camera / recycler_view_formats / button_google.
+    Permissions     AllPermissionsActivity; "Runtime" section heading.
+    Scan image      ScanBarcodeFromFileActivity, title "Scan"; crop_image_view.
+                    (Opens the SYSTEM picker — we assert only REACHING it.)
+
+  We never clear_data(): that revokes the camera permission the fresh eval
+  emulator ships with and would wedge the Scan tab behind a permission dialog.
+  restart_app() (force-stop + relaunch) preserves permissions and gives each test
+  its own clean entry point.

+"""STATES lane — every test is a TRIGGER -> a state that FLIPPED, PAIRED with the
+app-authored consequence of that flip. This lane is the sole owner of `checked`,
+`selected`, and `enabled` transitions, plus SETTINGS/mode PERSISTENCE across
+process death.
+
+The app is a QR & Barcode Scanner (4 bottom tabs Scan/Create/History/Settings).
+The state behaviors exercised here, each RE-VERIFIED on the running original:
+
+  * Conditional confirm ENABLE-gating on Create input screens — the confirm
+    toolbar item (item_create_barcode) is DISABLED while the field is invalid and
+    ENABLED at exactly the point the per-format validator is satisfied
+    (Text: any non-blank; EAN-13: exactly 12 digits, still disabled at 3).
+  * Settings Switch toggle + PERSISTENCE — flip a row's switch_button (targeted by
+    bounds-containment, since every row shares that id), force_stop_and_relaunch(),
+    and assert the NEW value survived. Restored afterwards.
+  * Radio mutual-exclusion state machines — Theme / Camera / Search-engine: select
+    a non-selected radio; it becomes checked and the previously-selected one
+    becomes UNchecked. Restored afterwards.
+  * Checkbox toggle — Supported-formats row and Wi-Fi "Hidden": checked flips.
+
+Every expected before->after value is the value OBSERVED on the original app, not
+one derived from source. Every setting/mode/radio/checkbox is RESTORED so sibling
+lanes and re-runs are not poisoned, and each test NORMALISES the entry state it
+depends on so a leftover from an interrupted run cannot fail it. Because the
+emulator has no working FRONT camera, selecting it makes the app pop a blocking
+'Unable to access camera' dialog on the next launch; dismiss_blocking_dialog() is
+run after every launch so no single test's leftover can cascade into the rest.

+"""STRUCTURE lane — QR & Barcode Scanner.
+
+This lane owns exactly two things:
+  1. The GATE: the app launches to the foreground and its top-level surfaces
+     exist (the 4 bottom-nav tabs are present after launch). depth=0,
+     jump_kind="none". This is the one existence-style allowance.
+  2. Tree-SHAPE deltas: a user interaction changes the view tree's SHAPE — a
+     class of widget appears/disappears, a new surface's structural signature
+     shows up, a container set changes. We prove only that the shape changed in
+     the OBSERVED direction (surface_changed True; a widget-class count went
+     up/down; scanner_view gone / edit_text present). We assert DIRECTIONAL
+     deltas, never absolute node counts, so a faithful recreation with slightly
+     different padding/rows still passes.
+
+Everything about content/text/state/reachability is CEDED to the other lanes.
+
+Ground truth was observed on the running original (2026-08-06):
+  Scan     -> scanner_view; 0 Switch; 0 EditText; bottom nav w/ 4 tabs.
+  Create   -> scroll_view; button_text/url/wifi/... (8 button_* rows); no scanner_view.
+  Text in  -> edit_text + item_create_barcode confirm; the button_* list is gone.
+  Result   -> image_view_barcode + button_copy/save_as_*/share_as_* ; no scanner_view.
+  Settings -> scroll_view; many switch_button Switch rows (>=5); no scanner_view.
+  History  -> tab_layout + view_pager + recycler_view_history; tabs All/Favorites.
+  BarcodeAll (Create->button_create_barcode) -> scroll_view w/ many button_* rows,
+             title "Create barcode".

+"""TEXT lane — CONTENT/OUTPUT strings that an ACTION REVEALS on this QR & Barcode
+Scanner. Every test is TRIGGER -> OBSERVATION of a specific string the app RENDERED,
+asserted by EXACT-string equality against the value OBSERVED on the running original
+(never derived from the source tree, never a version/build constant).
+
+This lane owns the CHROME around the encoded value: toolbar TITLES produced by
+navigating, Create-screen section HEADERS, the BUTTON-LABEL set a result screen
+reveals (and the label a CREATED result does NOT reveal), Settings row LABELS,
+bottom-nav / tab CONTENT-DESC, and the History row FORMAT label. It does NOT assert
+text_view_barcode_text encoded values — that is the COMPUTATION lane's fact.
+
+Row buttons here are FrameLayouts (button_copy/button_print/...) whose visible label
+lives on a CHILD TextView (resource-id text_view), so a label is read by its exact
+visible text via find_node_ci(), never off the container's own (empty) text.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,

+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))

+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):

+    python3 android_testgen_kit.py lint         <results_dir>

+"""COMPUTATION test suite for Arity (org.woheller69.arity).
+
+Lane: CORE FUNCTION input -> output. Sole owner of jump_kind="value".
+The calculator evaluates LIVE on each keystroke: typing an arity-0 expression
+into the `input` EditText updates the TOP `result` TextView with no Enter needed.
+
+Every expected string below was OBSERVED on the running original app (never
+computed in Python, never read from source). `type_text` maps ASCII operators
+*->x, /->div, -->minus in the INPUT echo, but the RESULT string uses plain
+formatting (e.g. 7-9 -> "-2"). We assert the RESULT string exactly as displayed.
+
+Arity quirks that surprised naive expectation (all confirmed on device):
+  9%3   -> 0.27   ('%' is PERCENT: 9 x 3/100, NOT modulo)
+  0.5!  -> 0.88622692545276   (factorial via gamma)
+  1/3   -> 0.33333333333333   (14 significant digits, truncated not rounded up)
+  50%   -> 0.5
+A 1-arg function (sin(x), x^2) clears the numeric result and shows the 2D graph;
+a 2-arg function (x*y) shows the 3D graph -- the computed OUTPUT is a plot.

+"""INTERACTION suite for Arity (scientific graphing calculator).
+
+Lane = EFFECT-BY-CONSEQUENCE on user DATA: the history-row lifecycle (create,
+read-back, load-into-input, edit-by-reload, delete), multi-step sequences where
+each action depends on the last (ans chaining), multi-record integrity, DATA
+persistence across real process death, and long-press context deletion (this
+file is the SOLE owner of long-press).
+
+Every behaviour below was confirmed on the running original before being asserted.
+
+KEY GROUND-TRUTH FINDING (why persistence uses HOME then a kill, not a bare
+force-stop): `am force-stop` alone is too abrupt — it kills the process before
+Calculator.onPause() can flush history.save()/defs.save() to disk, so a created
+row is LOST. Sending the app to background first (HOME) fires onPause (the save),
+THEN killing the process and relaunching returns the row from DISK. The kill is
+real and verified (pidof empties, the pid changes on relaunch), so this still
+discriminates an in-memory-only recreation: only data written to disk can come
+back after the process is gone. This is the honest, reproducible persistence
+probe on THIS app.
+
+DATA MODEL (from recon, all re-verified live):
+  * `input`  EditText  — the entry field (node_by_id "input", class EditText).
+  * `result` TextView  — live evaluation of the current input (top of screen).
+  * `history` ListView — rows; each row has an `input` TextView (the expression),
+    an `equals_separator` TextView (" = "), and a `result` TextView (the value).
+    Graph-function rows (sin(x), x^2, x*y ...) have an EMPTY result cell, but the
+    result TextView still exists, so the expression and result columns stay 1:1.
+  * clear_data() reseeds a deterministic 6-row history, top->bottom:
+      x^2, sin(x), ln(e^100), e^(i×pi), sqrt(pi)÷0.5!,
+      4×sin(x^2+y^2)÷(1+x^2+y^2)×cos(x×y)
+  * type_text maps '*'->×, '/'->÷, '-'->−, so "5*5" enters "5×5".

+"""NAVIGATION suite for Arity (scientific graphing calculator).
+
+Lane = surface REACHABILITY + back-stack integrity. This file is the SOLE owner
+of jump_kind="reach" and of the deep (depth>=2) chains; every jump is PROVEN by
+`and_reach(before, after, target, source)` — the TARGET surface's discriminating
+element APPEARED *and* the SOURCE surface's DISAPPEARED. A screen that was in the
+tree all along is never "reached".
+
+Every path below was confirmed on the running original before being asserted.
+
+DISCRIMINATOR NOTES (why these node_keys and not the obvious ones):
+  * The toolbar title "Arity" is shown on BOTH the main Calculator AND ShowGraph,
+    so "Arity" can NOT discriminate ShowGraph. ShowGraph is identified by its
+    unique "Navigate up" ImageButton (absent on the calculator shell) and its
+    id=`container` FrameLayout.
+  * `and_reach` matches by case-insensitive SUBSTRING, and every activity has a
+    `FrameLayout|action_bar_container`. So "container" as a *source* discriminator
+    would false-match action_bar_container and never look "disappeared". The main
+    surface is therefore discriminated by "View|digits" (the canvas keypad), which
+    exists nowhere else.
+  * After BACK from ShowGraph the input still holds e.g. `sin(x)`, so the input
+    node's key is "EditText|sin(x)" (text beats id in node_key). "View|digits" is
+    the reliable "we are home again" signal.
+

+"""STATES suite for Arity (scientific graphing calculator).
+
+Lane = STATE CHANGE only: checked / enabled / selected / focused transitions
+PAIRED with their app-authored consequence, page-level state machines, conditional
+enable/disable, and SETTINGS / mode persistence across process death. This file is
+the SOLE owner of the `checked` and `focused` attributes.
+
+Every transition below was VERIFIED on the running original before being asserted.
+
+GROUND TRUTH established on the live app (dump attribute strings are "true"/"false"):
+  * ALPHA KEYBOARD (the headline page-level state machine, VISIBLE<->GONE): the
+    canvas ARROW key (digits grid row0 col5, derived from the live `digits` bounds)
+    toggles a SECOND canvas keyboard `alpha`. Absent -> tap -> `alpha` present at
+    ~[0,1444][1080,1854] (history shrinks to make room) -> tap -> `alpha` GONE.
+  * result CONDITIONAL ENABLE: the top `result` TextView (y-top < 500) is
+    enabled=false when `input` is empty and enabled=true once a valid arity-0
+    expression is entered (e.g. "2+3" -> enabled=true, text "5"). Backspacing to
+    empty flips it back to enabled=false. (The VALUE "5" is computation's lane; the
+    ENABLED flip is this lane's.)
+  * input AUTO-FOCUS + focus transition: on launch `input` (EditText) is the SOLE
+    focused=true node. Opening the overflow menu popup takes focus away from
+    `input` (no node focused), and dismissing the popup RESTORES focus to `input`.
+  * 3D SHADING (Settings, SAFE radio dialog): two CheckedTextView "Smooth, slower"
+    (default checked=true) / "Flat, faster" (checked=false). Selecting an option
+    WRITES the pref and CLOSES the dialog but does NOT kill the app. Re-opening
+    shows the chosen option checked=true, the other checked=false.
+  * 3D RESOLUTION (Settings, SAFE radio dialog): CheckedTextView options
+    "256 x 256" / "144 x 144" (default checked) / "72 x 72" / "36 x 36" / "24 x 24".
+  * SETTINGS PERSISTENCE: picking "Flat, faster" (or a non-default resolution) then
+    force_stop_and_relaunch() -> the choice is STILL checked on re-open. clear_data()
+    resets these prefs to their defaults, so each test starts from a known baseline;
+    tests that leave a non-default also RESTORE the default explicitly.
+
+OFF-LIMITS (verified, deliberately never touched): the "Dynamic colors"
+SwitchPreference calls Runtime.getRuntime().exit(0) ~500ms after a toggle and KILLS
+the app — this suite NEVER taps, toggles, or clicks it. Also avoided: "Capture
+screenshot", "Clear history", "Clear user definitions", "About".

+"""STRUCTURE suite for Arity (scientific graphing calculator).
+
+Lane = the GATE (app launches, top-level surfaces exist) + tree-SHAPE deltas
+(an interaction that adds/removes a CLASS of widget or a window layer). We only
+assert SHAPE — which subtree is present/absent, node/row counts — never content
+strings, computed values, checked-state, focus, or reachability.
+
+Every fact below was confirmed on the running original before being asserted:
+  - launch: result + input + history(ListView) + digits(canvas View) coexist;
+    graph / graph3d / alpha absent.
+  - type sin(x): `graph` View appears, history ListView subtree disappears.
+    NOTE: merely clearing the input does NOT hide `graph`; typing a plain
+    arithmetic expression (arity-0) is what reverts the surface to the list
+    shell — that is the honest reverse (verified on the original).
+  - type x*y:    `graph3d` View appears (rendered as a green wireframe mesh).
+  - overflow ("More options"): a popup menu subtree appears.
+  - ARROW key (digits row0 col5, derived from digits._bounds): `alpha` canvas
+    keyboard appears; tap again -> gone.
+  - overflow -> Settings: history ListView subtree -> a RecyclerView of prefs.

+"""TEXT suite for Arity (org.woheller69.arity) — scientific graphing calculator.
+
+Lane = CONTENT / OUTPUT strings. This file is the SOLE owner of exact-string
+equality: the strings an interaction PRODUCES, app-unique static labels a
+recreation must get right (screen titles, section headers, menu item labels,
+content-desc), the history-row equals separator, seeded-row content strings, and
+the one class of text that never reaches the view tree (the Help WebView body and
+the canvas keyboard glyphs) — that opaque core is what the 5 VLM records cover.
+
+It does NOT poach:
+  * the COMPUTED value of an expression -> computation (we read seeded FIXED
+    content like "100"/"-1"/"2" and the ECHO of a typed expression, never an
+    arithmetic oracle);
+  * a label we TAP to navigate -> navigation (we open a surface with an
+    and_enter_* / and_reach_* helper and then assert its CONTENT strings);
+  * checked/focus bits -> states; widget-class presence -> structure.
+
+Every string below was OBSERVED on the running original app before being
+asserted (never read from source, never a version/build string). The multiply
+glyph is U+00D7 (×) and the divide glyph is U+00F7 (÷) — the raw ASCII the user
+types is mapped to those by the calculator, so the ECHOED content contains the
+glyphs, which we assert verbatim.
+
+VERIFIED text facts (re-confirmed live):
+  * seeded history (clear_data): equals_separator == " = " (surrounding spaces);
+    result content strings "100", "-1", "2"; expression content strings
+    "ln(e^100)", "e^(i×pi)", "sqrt(pi)÷0.5!".
+  * producing a row: type "8*8" + Enter -> a NEW top row whose expression echo is
+    "8×8" and which carries a " = " separator (absent before, present after).
+  * input echo: type "2+3" -> the top `input` EditText text becomes "2+3".
+  * toolbar titles: "Arity" (main + ShowGraph), "Settings", "Help",
+    "User definitions".
+  * overflow menu items: "User definitions", "Clear history", "Settings",
+    "Help", "About".
+  * Settings pref titles: "3D Shading", "3D Resolution", "Dynamic colors"
+    (READ only — tapping "Dynamic colors" kills the app).
+  * ShowGraph overflow items: "Capture screenshot", "Set center" (READ only).
+  * Set-center dialog title: "Set center coordinates" (depth 3).
+  * Help WebView body + canvas keyboard glyphs are RENDERED, not in the tree ->
+    the 5 VLM records.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>
+    python3 android_testgen_kit.py audit_depth  <testgen_dir> [results_dir]

+"""COMPUTATION module for CalcYou — the CORE FUNCTION, input -> output.
+
+This lane owns exactly one thing: drive a real input through the user path and
+assert the SPECIFIC computed value that appears. A shell that renders the keypad
+or the converter fields but computes nothing must FAIL every one of these.
+
+Two computation surfaces, both driven through the GUI only:
+  (1) the CALCULATOR — digits are TextViews (locate by text); operators are
+      icon-only clickable Views with no text/desc (locate by their row/column in
+      the live keypad grid, re-derived from every fresh dump — never a pixel
+      literal). Computation is ALWAYS button-driven: typing into the display
+      EditText bypasses evaluation. We read the live preview TextView (below the
+      display) and the post-'=' EditText.
+  (2) the UNIT CONVERTER — type a value into the left EditText, read the target
+      unit's converted value out of the results list. Reached via the menu button
+      -> "Unit Converter" -> a category card (depth>=1, backed by an and_enter_*
+      helper). The selected unit persists across restart_app(), so every converter
+      test ENSURES its expected default unit (selecting it via the picker if a
+      prior run left another) before asserting.
+
+Every asserted number was OBSERVED on the running original app; none is computed
+here or read from the source. Numeric comparison is tolerant (float parse with an
+epsilon, or prefix) because trailing-zero trimming / sig-digit count may differ.

+"""INTERACTION module for CalcYou — EFFECT-BY-CONSEQUENCE on user DATA.
+
+This lane owns CRUD on user data, multi-step (3+) dependent sequences, multi-record
+integrity, DATA persistence across process death, and (sole owner) long-press /
+context menus. Every test is a TRIGGER SEQUENCE -> a DATA/record change read back
+out of a FRESH ui(). A dead shell that draws a button but mutates no data FAILS.
+
+Ground truth: every flow below was driven on the running original before it was
+authored (calc history push/restore, long-press clear-all, converter favorites +
+process-death persistence, graphing add/remove/add-two/add-constant, character-input
+build/backspace). Assertions re-derive the expected DATA state from what was OBSERVED.
+
+CalcYou-specific mechanics that shape these tests (recon-verified + confirmed live):
+  * Drawer is opened by the ONLY Button (hamburger); NEVER open_drawer() (it drops
+    to the launcher). Top-level BACK EXITS — switch top-level screens via the drawer;
+    back() only closes a dialog/picker.
+  * Calc operators are icon-only Views with no text/desc: the operator COLUMN x and
+    each row y are DERIVED from live digit-TextView centers + the bottom-row Views,
+    so no pixel literal is written. delete = bottom-row 3rd clickable View; its
+    LONG-PRESS clears the whole display; a normal tap removes one char.
+  * A tapped converter tile's LABEL persists as the category HEADER, so a SIBLING
+    tile is used as the reach `source` (it vanishes off the grid).
+  * The ONLY persisted data is Unit Converter favorites + selected-unit-per-category
+    (DataStore). The process-death tests target those, never the calculator (which
+    resets to '' on relaunch).

+"""NAVIGATION module for CalcYou — surface REACHABILITY + back-stack integrity.
+
+This lane is the SOLE owner of jump_kind="reach" and of the deep (depth>=2)
+navigation chains; the other lanes stay shallow so real depth is measured here.
+Every reach is PROVEN with the kit's and_reach(before, after, target, source):
+it returns True only when the destination's discriminating element newly APPEARED
+*and* the origin's element DISAPPEARED — a screen that was in the dump all along
+was never reached. All targets/sources below were OBSERVED on the running original.
+
+CalcYou-specific mechanics that shape every test here (recon-verified):
+  * The four top-level screens are reached through a NAVIGATION DRAWER opened by
+    the single Menu (hamburger) Button — NEVER open_drawer() (its left-edge swipe
+    is eaten by the keypad or drops the app to the launcher).
+  * TOP-LEVEL BACK EXITS THE APP (drawer nav is popBackStack()+navigate(), one
+    back-stack entry). So to move BETWEEN top-level screens we ALWAYS reopen the
+    drawer; back() is used ONLY to dismiss a dialog / full-screen picker, where it
+    returns to the underlying surface.
+  * The Calculator display EditText carries no text, so it has no surface key; a
+    keypad digit ("7") is the reliable Calculator-only source element.

+"""STATES module for CalcYou — CHECKED/SELECTED/ENABLED/FOCUSED transitions PAIRED
+with their app-authored CONSEQUENCE, page-level state machines, conditional
+enable/disable, and SETTINGS/mode PERSISTENCE across process death.
+
+This lane is the SOLE owner of `checked`/`focused` and of every mode flip. Every
+test captures a BEFORE state out of a fresh ui(), triggers the flip through the
+user path, re-dumps, asserts the state FLIPPED **and** that the app-authored
+consequence followed, then restores. A dead shell that renders a toggle but wires
+no state change FAILS these — a bare label flip with no consequence is worthless.
+
+Ground truth (every case reproduced on the RUNNING original before authoring):
+  * RAD/DEG toggle (calc End scientific panel): a bottom-right TextView, default
+    label 'RAD'; tapping flips it to 'DEG'. CONSEQUENCE: trig mode changes —
+    sin(30) evaluates to the radian value '‒0.988031624' in RAD, to '0.5' in DEG.
+    The mode is NOT persisted (relaunch resets to RAD). Confirmed live.
+  * Graphing function visibility (Hide/Show): after adding a function, its row has
+    an IconButton content-desc='Hide function' <-> 'Show function'. Confirmed flip;
+    CONSEQUENCE = the plotted curve is shown/hidden on the canvas (VLM).
+  * Add-function OK enable/disable BY CONSEQUENCE (the XML `enabled` attr is
+    unreliable for Compose here): empty -> error 'Expression is empty', OK adds
+    nothing + dialog stays; invalid 'xx@@' -> error 'Unexpected token at index 2',
+    OK adds nothing + dialog stays; valid chip -> error clears, OK adds a row +
+    dialog dismisses. This is a page-level state machine.
+  * Unit-picker selected-row highlight (surfaceVariant bg — VLM/color, the row
+    TextView itself reports selected=false) + selected-unit CONSEQUENCE (picking
+    'Foot' closes the picker and the category's right unit field becomes 'Foot').
+  * Favorite heart toggle: tapping the far-right IconButton on a unit row moves the
+    unit into a 'Favorites' section; favorites PERSIST across process death
+    (DataStore). Selected-unit-per-category ALSO persists ('Foot' survives a kill).
+    The calculator display does NOT persist ('789' -> '' on relaunch).
+
+CalcYou mechanics (recon-verified + confirmed live) every test obeys:
+  * Drawer opens via the ONLY Button (hamburger); NEVER open_drawer() (its
+    left-edge swipe is eaten by the keypad / drops to the launcher). Top-level BACK
+    EXITS — switch top-level screens via the drawer; back() only closes a picker.
+  * The keypad is a 3-panel swipe strip: Center (digits/ops), Start (sin/cos/... —
+    one swipe RIGHT), End (RAD/DEG + inverse trig — one swipe LEFT). `sin` and the
+    digits live on DIFFERENT panels, so building sin(30) crosses panels. A panel
+    swipe stays on the same SURFACE (Calculator) — it is depth=0, not a surface cross.
+  * The '=' and operators are icon-only Views with no text/desc; '=' is the
+    bottom-row rightmost clickable View (derived, never a pixel literal).

+  (1) the launch GATE: the app reaches the foreground and its top-level surface
+      (the Calculator display + full digit keypad) exists;
+  (2) tree-SHAPE deltas: an interaction that changes the SHAPE of the view tree —
+      node counts / a class of widget appearing or disappearing / an empty list
+      becoming populated — captured as a before->after delta and reversed where
+      possible. Content / state / focus / reachability are CEDED to other lanes.
+
+Every behavioral case is TRIGGER -> SHAPE-CHANGE, never "a view exists": a dead
+pixel-perfect shell that renders the widgets but wires no interaction must still
+fail these. All numbers below were OBSERVED on the running original app.

+"""TEXT module for CalcYou — CONTENT / OUTPUT strings an action PRODUCES.
+
+This lane is the SOLE owner of exact-string equality. Every case performs a
+trigger through the real user path, then reads the resulting string out of a
+FRESH ui() and asserts it matches what was OBSERVED on the running original —
+never a string read from the source tree, never a version/build literal. A shell
+that renders generic/placeholder wording, or wires no interaction, must FAIL.
+
+The discriminating half is the CHANGE: several cases assert a string is ABSENT
+before the trigger and PRESENT after (the add-function error transitions, the
+legend chip, the Favorites header, the g(x) prefix increment). Static app-unique
+strings this recreation must get right (the 11 Character-Input row labels, the
+`E = mc²` placeholder, unit-picker `Search`, the Length result unit names) are
+asserted by EXACT match — they are content a faithful recreation cannot fake with
+a placeholder.
+
+CalcYou-specific mechanics (recon-verified, and re-confirmed live before trusting):
+  * The four top-level screens are reached through the NAVIGATION DRAWER opened by
+    the single Menu (hamburger) Button — NEVER open_drawer() (its left-edge swipe
+    is eaten by the keypad or drops the app to the launcher).
+  * TOP-LEVEL BACK EXITS THE APP; back() is used ONLY to dismiss a dialog / the
+    full-screen unit picker, where it returns to the underlying surface.
+  * The top app-bar title stays "CalcYou Debug" on every portrait screen, so it is
+    NOT asserted as a per-screen label (a constant proves nothing).
+
+VLM budget for this file: EXACTLY 3 vlm_assert records. Strings are dump-readable,
+so VLM is reserved for text that is RENDERED but never reaches the view tree — the
+graphing CANVAS numeric axis/tick labels (verified: the graphing tree carries only
+the "CalcYou Debug" title, so every axis number is canvas-drawn).

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+"""Android TestGen Kit — the single source of every test helper, so a test's
+NAVIGATION DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded,
+and self-auditable.
+
+LOCATION AT RUNTIME: alongside the generated test files (testgen: $TESTGEN_DIR/eval/,
+eval: the restored eval dir). READ-ONLY — never edit, copy, or reimplement it.
+`import` it from every test file:
+
+    import os, sys
+    sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+    from android_testgen_kit import *          # noqa: F403
+
+WHY THIS EXISTS
+  Helpers used to be re-emitted verbatim into every generated test file (~370
+  lines x 6 files). That blew the output-token ceiling, forced a "write the script
+  in pieces" protocol, let each copy drift, and duplicated one API key into every
+  file. Everything mechanical now lives here; prompts carry only judgement.
+
+  Two orthogonal properties decide whether a suite really exercises an app:
+    * navigation DEPTH — how many SURFACES you cross before the assertion
+                         (0 = first screen, 1 = one page/dialog/sheet, 2+ = deeper)
+    * jump RIGOR       — what the assertion after the trigger actually checks
+  Prose alone let these drift, so every behavioral test DECLARES both:
+
+      @and_test(expects=("interaction_create_note", "interaction_create_note_vlm"))
+      def test_create_note():
+          ...
+          record("interaction_create_note", ok, "behavior_wrong: ...",
+                 depth=1, jump_kind="value", expect="list shows 'Milk'")
+
+  jump_kind (verbatim strings — audit/stats key off them):
+    "none"        no trigger; existence/gate only                  -> tier 0
+    "liveness"    only "did not crash / still foreground"          -> tier 1 (weak; never ship)
+    "reach"       a real surface jump: the TARGET surface's element
+                  APPEARED *and* the SOURCE surface's DISAPPEARED   -> tier 2
+    "transition"  a state flip (checked/enabled/selected/mode) with before->after -> tier 2
+    "value"       a specific expected value/content was asserted    -> tier 3
+
+WHAT A "SURFACE" IS ON ANDROID
+  NOT the Activity — single-Activity Compose/Fragment apps never change it, so
+  get_current_activity() cannot discriminate. A surface is the SET of visible
+  discriminating element keys: and_showing() -> {"Button|Save", "TextView|Total"}.
+  and_reach(before, after, target, source) therefore proves a real jump; reading a
+  flat tree for an always-present element cannot fake it.
+
+DETERMINISTIC DENOMINATOR
+  Scoring is eval_pass_case / origin_total_case, so a test function MUST contribute
+  the same number of records on every code path. @and_test(expects=(...)) owns the
+  try/except and back-fills any declared-but-unrecorded name as a failure, and
+  record() refuses duplicates. N is a literal in the decorator.
+
+PORTABILITY (the same file scores the ORIGINAL and the RECREATION, whose package
+name differs): always use the module-level PACKAGE (argv[1]). Never write a package
+name, an .apk path, a /data/data path, or a pixel coordinate as a literal.
+    python3 android_testgen_kit.py lint_sources <dir>     # flags all of those
+
+SELF-AUDIT (report-only — these are GOALS, never a gate that blocks delivery):
+    python3 android_testgen_kit.py audit        <results_dir>
+    python3 android_testgen_kit.py lint         <results_dir>
+    python3 android_testgen_kit.py lint_sources <testgen_dir>

+#!/usr/bin/env python3
+"""COMPUTATION suite for ConnectYou (com.bnyro.contacts.* — package is argv[1]).
+
+Lane = CORE FUNCTION, input -> output VALUE. This module is the sole owner of
+jump_kind="value". Every test drives a live query/name through the real user
+path and asserts the SPECIFIC value it observed the running app produce, out of
+a FRESH ui(). Nothing here is computed from source or a constant — the values
+below were all OBSERVED on the device during recon.
+
+The genuine input->output surfaces this app exposes (verified on device):
+
+  * Contacts SEARCH (S3, depth 1): top-bar Search icon opens an EditText (hint
+    "Search"); typing filters the list LIVE by a CASE-INSENSITIVE SUBSTRING on
+    the display name — verified: "Ali"->Alice Walker; "create" (interior of
+    "Zcreate...") matches; "alice" (lowercase) matches; a nonsense query yields
+    an EMPTY list; clearing the field restores the full list.
+  * Message COMPOSE contact search (S9, depth 1): Messages tab -> compose FAB
+    opens an EditText (hint "Search contacts"); typing a name filters the
+    contact SUGGESTION list. A "Start a new conversation" header is ALWAYS
+    present (it offers the raw query as a new thread), so the discriminator is
+    whether a real CONTACT NAME appears as a suggestion — verified:
+    "Walker"->"Alice Walker" present; "Zqzqzq"->absent (header still there).
+  * Name -> SECTION LETTER (S0): a created contact appears under a single-letter
+    section header equal to the UPPERCASED first character of its name (verified:
+    "Ktest..." -> header "K"; the header sits directly above the row).
+  * Name -> AVATAR INITIAL (S5 detail): the round avatar's letter equals the
+    first character of the name; it IS a real TextView in the dump, so the VALUE
+    is a rule assertion. The single VLM budgeted for this lane asks only about
+    the RENDERED avatar (large letter inside a coloured blob shape) — a property
+    the dump does NOT carry.
+
+Reused app-specific glue (adapted from the interaction suite; NOT kit
+reimplementations): grant_perms / on_contacts_list / reach_list / open_home /
+bottom_right_button / et_for_label / uniq / create_contact.
+SMS send/threads are GATED and the dialer is not reachable — neither is tested.

+
+Lane = EFFECT-BY-CONSEQUENCE on user DATA: contact CRUD, multi-step sequences,
+multi-record integrity, DATA persistence across process death, and long-press /
+context menus (sole owner).
+
+Every test drives the app through the real user path, performs a data operation,
+then reads the consequence back out of a FRESH ui() and asserts the specific
+value/record produced. Names are unique per test ("Zeta ...", "Persisty ...") so
+a read-back cannot collide with the pre-existing "Alice Walker".
+
+Verified on device during recon:
+  * Contacts FAB / editor save FAB = the bottom-right clickable Button (y>0.7*H).
+  * Editor EditTexts sit ABOVE their label TextView; locate by label, never a
+    fixed index (the order shifts when "Show more fields" is expanded).
+  * A field BELOW the fold cannot be focused by a raw tap — the keyboard appears
+    and re-lays-out the form, so the tap lands on the first field instead. The
+    fix (type_field): hide the keyboard, scroll the field's label into the upper
+    ~45% of the screen, THEN type. Verified: the value then lands in the right
+    field.
+  * clear_data() revokes runtime permissions -> a permission dialog appears on
+    relaunch; grant_perms() taps "Allow". Contacts live in the system provider,
+    so they survive both pm clear and force-stop (that is what the persistence
+    test exploits).
+  * A force-stop+relaunch RESTORES the last screen (Compose saves the back-stack),
+    so open_home()/reach_list() actively drive back to the Contacts list.
+  * Long-press a contact row -> selection mode: a "N selected" bar + Copy/Move/
+    Share/Delete actions replace the normal top bar; the row shows a checkmark.
+  * Favorites-only filter is a real CheckBox; favoriting a fresh contact (1 tap =
+    ON) then applying it shows the favorite and hides a non-favorite.

+
+Lane: surface REACHABILITY + back-stack integrity. This file is the SOLE owner of
+jump_kind="reach" and of the deep (depth>=2) navigation chains; the other five
+lanes stay shallow so real navigation depth is measured here.
+
+Every jump is proven with and_reach(before, after, target, source): the TARGET
+surface's discriminating element APPEARED **and** the SOURCE surface's element
+DISAPPEARED — a screen that was in the dump all along was never "reached".
+Reaching a screen by relaunching the app is NOT navigation (forbidden for reach).
+
+Back-stack tests navigate down N hops and then and_back()/BACK N times, asserting
+the expected surface after each pop.
+
+Content strings are ceded to the text lane, state flips to states, CRUD to
+interaction. This file proves it can GET to a surface and COME BACK.
+
+All source/target keys below were confirmed on the RUNNING original app by dumping
+and_showing() before/after each trigger, and every VLM question was written from
+the screenshot actually captured on the original — not guessed. Portable: nothing
+is keyed on a literal package name or pixel coordinate; the FAB is located by
+class+position and every trigger by content-desc / visible label.

+"""STATES test suite for ConnectYou (contacts + SMS manager, Jetpack Compose).
+
+Lane: widget STATE through a BEFORE -> interact -> AFTER path, each flip PAIRED
+with its app-authored CONSEQUENCE. This file is the SOLE owner of `checked`,
+`selected` and `focused`, and of SETTINGS / mode PERSISTENCE across process death.
+
+Every case reads the state out of a FRESH ui() BEFORE, drives the user path, reads
+a FRESH ui() AFTER, asserts the transition AND the consequence, then RESTORES any
+global/persistent state it changed (Favorites-only filter, Theme, Start tab,
+toggles) on the success path AND every early-return path so tests stay independent
+and never change which tab the app launches on for later tests/lanes.
+
+Ground truth (all confirmed on the RUNNING original by dumping ui() before/after):
+  * Settings segmented selectors (Theme, Start tab, Automatic backup) and the
+    APPEARANCE/MESSAGES/BEHAVIOR switches EXPOSE `checked` on their container View
+    -> RULE assertions (recon expected them dump-invisible; they are not).
+  * The Favorites-only Sort/Filter control is a real CheckBox exposing `checked`.
+  * The bottom-nav selected tab is a `View` with `selected="true"` spanning that
+    half of the bar -> RULE assertion for which tab is active / persisted.
+  * The contact-detail Favorite star does NOT flip `checked` (stays false) though
+    its icon fills -> the ONE genuinely rendered-only flip here -> VLM.
+  * Save FAB is ALWAYS enabled (even with every field empty) -> no conditional
+    enable/disable flip exists, so that recon row is intentionally DROPPED.
+
+VLM is spent only on rendered-only properties (theme background darkening, the
+selected bottom-nav pill highlight, the Favorite star fill) — never on a value the
+dump already exposes as `checked`.
+
+Portable: nothing is keyed on a literal package name, pixel coordinate, deep link
+or device serial; every control is located by class + visible label + content-desc
+and every coordinate is derived from ui() at runtime. Every locate/navigation step
+re-dumps with retries so an in-flight Compose animation cannot flake an assertion.

+"""TEXT / CONTENT-OUTPUT test suite for ConnectYou (contacts + SMS manager,
+Jetpack Compose, single Activity).
+
+Lane: exact-string equality on CONTENT that an action PRODUCES or REVEALS — a
+type-chip label that flips when you pick a type, a screen title, section headers,
+an input hint, a control's content-desc, a status/warning banner. This file is the
+SOLE owner of exact-string assertions; it never claims a computed number (that is
+computation), a checked bit (states), a widget's mere presence (structure), or a
+label tapped purely to navigate (navigation's trigger).
+
+jump_kind convention for this lane (value is reserved for computation):
+  * "transition" — a string PRODUCED by a before->after action (chip "Custom" ->
+                   "Mobile"; compose header appears after typing). `expect` names
+                   the produced string.
+  * "none"       — a static content string simply REVEALED by opening a surface
+                   (a menu item, a title, a hint). `expect` still carries the exact
+                   observed string so the assertion is self-documenting.
+
+Every string below was OBSERVED on the RUNNING original by dumping the tree at the
+relevant surface. Strings that reach the view tree are asserted as RULES (exact,
+case-insensitive substring via find_node_ci / all_text). The only two VLM records
+target genuinely rendered-only properties that never reach the dump: the Messages
+warning banner's pink/red banner COLOR (its text is a rule) and the Messages
+empty-state sad-face ILLUSTRATION (a vector/canvas with no caption in the tree).
+
+Portable: nothing is keyed on a literal package name, resource-id prefix, or pixel
+coordinate; every trigger is located by class + visible label + content-desc, and
+the FAB by class + bottom-right position.
+
+CEDED to avoid double-ownership: the "Show more fields"->"Show less" label flip is
+owned by the STATES lane (state-machine consequence); contact-name -> section
+letter is owned by COMPUTATION. Neither is re-asserted here.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# 1. Dependencies
+# -----------------------------------------------------------------------------
+# Erbele is a pure macOS / Cocoa application written in Swift + Objective-C and
+# built with Xcode. It has NO third-party package dependencies:
+#   * no CocoaPods (no Podfile)
+#   * no Carthage  (no Cartfile)
+#   * no Swift Package Manager (no Package.swift, no packageReferences)
+# It links only against system frameworks (Cocoa, WebKit, QuartzCore, Carbon,
+# etc.) plus the Swift/Clang toolchain that ships with Xcode.
+#
+# The only build-time requirement is the Xcode toolchain itself. We verify it
+# is present (this environment already has Xcode installed); if the Xcode
+# command-line tools were ever missing on a clean machine, the idempotent
+# install line below sets them up.

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The
+         reference (.pipeline_refapp) and helpers are excluded here.
+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+Every expected value asserted below was OBSERVED on the reference app (recon ## COMPUTATION).
+
+Four AX facts this module obeys:
+  1. Text-menu commands are SELECTION-GATED — a disabled item's AXPress is a silent no-op, so
+     select_all(ax) / set_range(ax, loc) runs BEFORE rb_reach_menu(ax, ["Text", item]).
+  2. set_text() (AXValue write) fills the document and refreshes the gutter but does NOT refresh
+     the status bar — 'Length: N' assertions use real keystrokes (type_chars).
+  3. Menu items are only valid once the menu is open — every invocation goes through
+     rb_reach_menu / rb_enter_menu_item (they open, check enabled, then press).
+  4. No document can be opened from disk (NSOpenPanel is out-of-process) — every input is
+     seeded with set_text().

+"""AX MENU lane — Erbele (`APP_NAME=macos-abentele-erbele`), a document-based text editor.
+
+Everything asserted here comes from recon.md `## MENUS` (+ `## AX_TREE`, `## VISUAL`), i.e.
+from facts OBSERVED by driving the reference app.
+
+THE #1 AX FACT FOR THIS LANE: a macOS menu item is only VALID once its menu has been
+OPENED. With the menu closed `AXEnabled` is False for everything and the View-menu toggle
+titles are raw xib placeholders (`'Show Line Numbers <do not localise>'`), and a disabled
+item's `AXPress` is a silent no-op. Every inventory read therefore goes through
+`menu_map()` / `rb_enter_submenu()` (open → read validated title/enabled/mark/cmd/mods →
+close) and every activation goes through `rb_reach_menu()` (open the chain, press the leaf
+only if it is enabled).
+
+pytest module: Test* classes, test_* methods taking the `ax` fixture, plain asserts, one
+`@pytest.mark.rb(...)` declaration per test. No argparse / __main__ / self-written JSON.

+"""AX STATE verification suite for Erbele (macos-abentele-erbele).
+
+Lane: CHECKED / ENABLED / focus / selection-state assertions.
+
+Everything asserted here comes from the recon golden model (`recon.md`, sections
+`## APP`, `## AX_TREE`, `## STATE`).  The single most important AX fact for this
+lane: **macOS menu items are only VALID once their menu has been OPENED** — with
+the menu closed every `AXEnabled` reads `False` and the View-menu toggle titles are
+raw xib placeholders containing `'<do not localise>'`.  Therefore every enabled /
+mark / title read below goes through `menu_map()` / `menu_title_containing()` /
+`rb_enter_menu_item()` / `rb_reach_menu()`, which open the menu first.
+
+Erbele's View toggles carry **no** `AXMenuItemMarkChar`; they signal their state by
+flipping their TITLE (`Hide Line Numbers` <-> `Show Line Numbers`).

+"""AX STRUCTURE lane — Erbele (macos-abentele-erbele), document-based text editor.
+
+Every fact asserted here was OBSERVED on the reference app and is recorded in
+recon.md (`## APP`, `## AX_TREE`, `## STRUCTURE` S1–S19, `## STATE` table T).
+
+Shape is deliberately behavioural: only the 3 gate tests are existence checks
+(jump_kind="none"); everything else snapshots the widget tree BEFORE a real
+navigation, navigates, snapshots AFTER, and asserts the recorded delta — so a
+recreation that merely creates correctly-named widgets fails most of the suite.

+"""AX TEXT-content tests for Erbele (macos-abentele-erbele) — document-based text editor.
+
+Every expected string below comes from the recon golden model (`## TEXT`, `## AX_TREE`,
+`## COMPUTATION`). Nothing here asserts version strings, dates/timestamps, the
+`Saved: <date>` variant, or rendered/opaque text (syntax colours, invisible glyphs) —
+those belong to the VISUAL lane (screenshot_assert).
+
+Two AX facts respected throughout:
+  1. `set_text()` (AXValue write) fills the document and refreshes the line-number gutter
+     but does NOT refresh the status bar — `Length: N` assertions use real keystrokes
+     (`type_chars`).
+  2. Menu titles are only valid once the menu has been OPENED (`menu_map`/`menu_titles`);
+     a closed-tree read returns raw xib placeholders containing '<do not localise>'.

+test_ax_buttons.py — AX button/toolbar interaction tests for Erbele (macOS plain-text /
+source-code editor, v6.1).
+
+Golden model: recon.md. The main document window opens automatically on launch (no reveal
+gesture), so tests use the plain `ax` fixture. All widget lookups go through the shared
+erbele_helpers (`eh`); the one reach is proven with rb_testgen_kit (`kit`). The autouse
+`check_app_alive` fixture in conftest already fails a test if the app process dies, so a
+plain "did not crash" (liveness) assertion is neither needed nor used here.
+
+Toolbar widgets under test (from recon):
+  * push buttons  New, Open, Save, Close
+  * a group holding the Live Find search `text_field` with a child `button` named "search"
+  * a `popup` named "more toolbar items" (the overflow menu)
+
+SAFETY (recon "Notes / pitfalls"): only the toolbar `New` button (adds a document) and the
+"more toolbar items" popup (opens an overflow menu) are PRESSED. `Open` (file dialog), `Save`
+(save dialog), `Close` (closes a document) and Quit are BLOCKING/destructive — they are only
+checked for EXISTENCE + AXEnabled, never pressed.
+
+Each test DECLARES its navigation depth + jump rigor via @pytest.mark.rb(depth, jump_kind,
+expect). Button existence/structure reads are depth=0 jump_kind="none"; pressing New is a
+same-window state flip (depth=0 jump_kind="transition", observed as a documents-list row-count
+increase); opening the overflow popup is a surface reach (depth=1 jump_kind="reach", proven with
+kit.rb_reach(before, after, ...)).

+test_ax_computation.py — "Computation" tests for the Erbele macOS text editor (v6.1).
+
+Erbele is a plain-text / source-code editor, so its deterministic "computation" is
+TEXT TRANSFORMATION (Text menu) plus LIVE STATUS (the status bar's Length field).
+Each test feeds input into the editor via AX and reads the transformed output back via
+AX, comparing to a SPECIFIC expected string/number derived from the golden model
+(recon.md) and the transform source (Classes/FRATextMenuController.m).
+
+Canonical transform path (verified in recon):
+    eh.set_editor_text(ax, INPUT) -> eh.focus_editor(ax) -> Edit ▸ Select All
+    -> Text ▸ <transform> (via eh.open_menu("Text") + eh.item_by_name + eh.press)
+    -> read editor AXValue and compare.
+
+`eh.open_menu(ax, "Text")` is a whitelisted navigation call, so an INLINE call in each
+transform test BACKS the declared depth=1 (rb_audit_depth). The live-status tests need
+real keystrokes (set_value does not refresh Length), so they use eh.type_in_editor and
+stay on the home surface (depth=0).
+
+No argparse / __main__ / self-written JSON — the runner scores via pytest and folds each
+@pytest.mark.rb(...) declaration into computation_results.json. Every test drives whatever
+app the `ax` fixture launched (reference OR recreation); no destructive/blocking menu items
+(Save/Open/Print/Close) are ever triggered.

+test_ax_states.py — AX state-verification tests for the Erbele macOS text editor.
+
+Every test reads widget state via AX attributes (AXEnabled, AXValue, settability,
+row counts, surface presence) and asserts a BEFORE→AFTER change or a specific value.
+Each test declares its navigation depth + jump rigor with @pytest.mark.rb(...); the
+conftest hook folds that into state_results.json. Tests use ONLY the `ax` fixture
+(the host launches the app — reference OR recreation) and the shared erbele_helpers,
+so the SAME suite drives both. Nothing here spawns the app or hardcodes a path.
+
+recon.md notes honored here:
+  - Main document window opens automatically on launch (no reveal gesture needed).
+  - Two text_area's: the editor's AXValue is settable; the line-number gutter's is not.
+  - Edit▸Copy / Edit▸Cut are DISABLED with no selection, ENABLED once text is selected.
+  - Toolbar 'New' adds a document row (Documents-list 1→2).
+  - Erbele▸Settings… opens the Preferences window (panes General/…/Appearance/Advanced).
+  - Text▸To UPPERCASE on a selection: 'hello world' → 'HELLO WORLD' (deterministic via AX).
+Never triggers Save/Open/Print/Close dialogs; never presses Quit/Delete/Revert.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.
+      2. name match, for launch.sh setups that run the app from a build/DerivedData

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The
+         reference (.pipeline_refapp) and helpers are excluded here.
+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_audit_depth('<testgen_dir>','<results_dir>')"

+"""AX COMPUTATION tests for MaciASL (macos-acidanthera-maciasl).
+
+Every expected value in this module is an OBSERVED input -> output pair taken from
+recon.md `## COMPUTATION` (rows C1-C14) and the `## STATE` rows that describe how an
+iASL preference changes compiler output.
+
+The app's "computation" surfaces are:
+  * the iASL compiler        : source text  -> Compiler Summary banner + notice table
+  * the editor transformations: selection   -> rewritten line (hex / comment / case)
+  * the patcher              : patch script -> status arithmetic + Before/After preview
+  * the SSDT generator       : 4 numbers    -> a generated ASL document
+
+All driving goes through the portable `rb_maciasl` helper (`mac`) and the `ax` fixture,
+so the identical file drives the reference app and any recreation.

+"""test_ax_menus.py — MENU lane for MaciASL (macos-acidanthera-maciasl).
+
+Behavioural coverage of the macOS menu bar: structure gates for the menu tree that
+`recon.md ## MENUS` / `## AX_TREE` recorded verbatim, then the SAFE menu items that
+cross into a real surface (Preferences, iASL Log, Device Properties, the Jump-to-Line
+sheet, the find bar, a new ACPI-table document, the Fonts panel) and the two editor
+transformations that change document text.
+
+Rules honoured here:
+  * every test takes the `ax` fixture (a fresh app instance per test) and starts with
+    `mac.wait_app_ready(ax, timeout=22)`;
+  * every test declares `@pytest.mark.rb(depth=, jump_kind=, expect=)` and every
+    depth>=1 / jump_kind="reach" claim is backed by a real `mac.rb_enter_*()` call;
+  * verdicts go through `kit.rb_reach` / `kit.rb_flip` / `kit.rb_value`;
+  * DESTRUCTIVE / BLOCKING items are never pressed — `File > Open…/Save…/Save As…/
+    Rename…/Move To…/Export Tableset.../Page Setup…/Print…`, `Help > MaciASL Help`,
+    `Check for Updates...`, any `Quit*` or `Close*`.  They are only ever read.

+
+Owns CHECKED / ENABLED / SELECTED / focus assertions ONLY.  Every fact asserted here
+was observed on the reference app and is recorded in recon.md `## STATE`.
+
+Contract:
+  * pytest methods on Test* classes taking the `ax` fixture (the fixture launches a
+    FRESH app instance per test and hands over an AXHelper bound to it).
+  * all driving goes through `rb_maciasl` (`mac`) so the SAME test drives the
+    reference app AND a recreation — no install path, no pid, no bundle id here.
+  * every test declares @pytest.mark.rb(depth=, jump_kind=, expect=);
+    depth>=1 is backed by a real mac.rb_enter_*() call, every `transition` is backed
+    by kit.rb_flip(before, after, ...) and every `value` by kit.rb_value(...).
+  * nothing on the never-press list is ever pressed.  `Check for Updates...` is
+    READ ONLY (it is disabled on the reference).

+"""AX TEXT lane -- MaciASL (macos-acidanthera-maciasl).
+
+Every string asserted here was OBSERVED on the reference app and is recorded in
+recon.md `## TEXT` / `## AX_TREE` / `## VISUAL`.  Nothing is read from source.
+
+Contract (recon.md `## HOW TO WRITE TESTS`):
+  * pytest module, `Test*` classes, `test_*` methods take the `ax` fixture
+    (NOT `ax_with_reset` -- this app has no popover and the Escape teardown can
+    close a sheet/panel a test still needs).
+  * every test starts with `wid = mac.wait_app_ready(ax, timeout=22)` -- that is
+    the reveal step for this app (a regular document app whose window is opened
+    automatically at launch; the helper blocks until the editor has text).
+  * widgets are located by SEMANTICS (AXTitle / AXDescription / visible value +
+    role) through `rb_maciasl`, never by child index or tree path.
+  * never presses anything on the never-press list (toolbar `Print`, `File >
+    Open.../Save...`, patch-sheet `Open`, `Quit/Close`, document close buttons).
+  * never asserts on a timestamp, a temp `iASLxxxxxx.aml` filename, a wall-clock
+    date, or the exact About version string (only the `Version \\d+\\.\\d` shape).

+# build.sh — Reproducible build for JSONExport (macOS, Swift/Xcode app)
+#
+# This project (github.com/Ahmed-Ali/JSONExport) is a self-contained Xcode
+# project written in Swift 4.2 with an Objective-C bridging header. It has NO
+# third-party dependencies: no CocoaPods (no Podfile), no Swift Package Manager
+# packages, no npm. The only build tool required is Xcode's command line tools.
+#
+# The one fix needed to build under modern Xcode (15.x) is raising the macOS
+# deployment target. The project ships with MACOSX_DEPLOYMENT_TARGET = 10.10,
+# which triggers:
+#     clang: error: SDK does not contain 'libarclite' ...
+# because Xcode 15 removed the legacy ARC runtime support library that old
+# deployment targets link against. We override the deployment target to 10.13
+# on the xcodebuild command line (a pure build-setting override — no source
+# code is modified), which resolves the error.

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The

+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+"""AX behavioural tests for the window buttons and the option checkboxes.
+
+Scope (recon §6 / §7 / §12):
+  * `Save`            — disabled at launch, enabled iff the last JSON parse succeeded,
+                        opens a directory-chooser NSOpenPanel **sheet** when pressed.
+  * `Open .json File` — always enabled, opens an NSOpenPanel **sheet** whose prompt
+                        button reads `Choose JSON file`; Escape dismisses it.
+  * window checkboxes `Constructors` / `Utility methods` — each press regenerates the
+                        model files, adding/removing the constructor and the
+                        `toJsonObject()` utility method.
+  * per-row checkboxes inside the generated-file preview rows.
+
+Every test declares its navigation depth + jump rigor with @pytest.mark.rb(...).
+Buttons and checkboxes are located by visible label (AXTitle/AXDescription) + role —
+never by child index or tree path — so the same module drives the reference and a
+recreation regardless of the UI framework used.
+
+NEVER pressed here: the window close/minimise/full-screen widgets, any Quit/Close/Delete
+menu item, or an open/save panel's `Choose` / `Choose JSON file` button. Sheets are always
+dismissed with Escape inside a `finally:`.

+"""AX COMPUTATION tests — JSON text IN -> generated model source files OUT.
+
+This is the app's real "computation": the JSON editor on the left is parsed on every

+currently selected target language, shaped by 4 option text fields (Root class name,
+Parent class name, Package name / first line, Classes prefix) and 2 checkboxes.
+
+Every test declares its navigation depth + jump rigor with @pytest.mark.rb(...) so the
+runner can fold depth/jump/tier/expect into computation_results.json.
+
+Facts asserted here were observed on the reference app (see recon.md §2/§3/§5/§8):

+"""test_ax_menus.py — menu-bar structure / shortcuts / activation for JSONExport.
+
+Golden model: recon.md §9 (full menu inventory + AXMenuItemCmdChar / modifier masks),
+§10 (About window), §12 (which rb_reach targets actually work).
+
+KEY AX FACT (verified): macOS exposes EVERY menu item in the AX tree even while the
+menu is CLOSED. So the structure tests below read `menu_item`s scoped to the
+`menu_bar_item` WITHOUT opening anything — fast and reliable. The flip side is that
+`kit.rb_reach()` cannot prove "a menu/submenu opened" (the tree does not change), so the
+only `reach` in this module is  JSONExport ▸ About JSONExport → the About window.
+
+Destructive items (Quit, Close, Delete, Clear Menu, New, Open…, Save…, Save As…,
+Print…, Page Setup…, Hide, Minimize, Start Speaking, Show Fonts, Show Colors,
+JSONExport Help, …) are READ ONLY — never activated.

+"""test_ax_states.py — AX STATE verification for the JSON-to-model-class converter app.
+
+Scope (recon.md §2 / §6 / §7 / §11):
+  * enabled / checked state of every interactive window widget (Save, Open .json File,
+    the two window-level checkboxes, the language pop-up, the option text fields)
+  * the per-language FIELD VISIBILITY rule: a hidden NSTextField is REMOVED from the AX
+    tree, so visibility is asserted by key presence/absence in `field_map(ax)` — there is
+    no AXHidden attribute to read.
+  * before -> after state flips (Save enable cycle, checkbox toggles, status label)
+  * per-row widget states inside the generated-files preview table
+
+Every test declares navigation depth + jump rigor via @pytest.mark.rb(...).
+The app is relaunched (and its defaults reset) by the `ax` fixture for every test, so the
+launch state asserted below is deterministic. Budget: <= 5 UI operations per test.

+"""test_ax_structure.py — JSONExport AX widget inventory / structure module.
+
+Presence + inventory of the single standard window described in recon.md §1:
+named buttons (`Save`, `Open .json File`), the four option text fields identified by
+their placeholder, the two window-level checkboxes, the static labels, the two
+scroll areas (JSON editor + generated-file preview table), the NoodleLineNumberView
+rulers, the top-level menu-bar menus, role diversity and real tree nesting.
+
+Plus the two required tree-shape `transition` tests:
+  * preview rows 0 -> 2 -> 0 as JSON is entered and cleared
+  * option fields 4 -> 2 when the language pop-up switches to `Swift - Struct`
+
+Every test declares depth + jump rigor with @pytest.mark.rb(...) (RB TestGen kit).
+The app is reached ONLY through the `ax` fixture — no app path, no direct AX app
+handle, so the same module drives the reference and any recreation.

+"""test_ax_text.py — TEXT CONTENT verification for JSONExport (AppKit, JSON -> model classes).
+
+Focus (recon.md §1 labels / §3 generated header + status strings / §4 status label /
+§5 option-field placeholders / §10 About-window text / §11 text-view attributes):
+read the EXACT text every text-bearing widget exposes (AXValue / AXTitle /
+AXPlaceholderValue / AXDescription) and compare it against the app-authored strings.
+
+Rules honoured here:
+  * pytest only — Test* classes, test_* methods taking the `ax` fixture, plain asserts.
+    No argparse, no __main__, no self-written results JSON (the runner scores via pytest).
+  * every test declares @pytest.mark.rb(depth=, jump_kind=, expect=).
+  * widgets are located by SEMANTICS (AXTitle / AXDescription / AXPlaceholderValue /
+    visible text + AXRole scoped to a named container), never by child index or tree path.
+  * visible label text is compared on WHITESPACE-NORMALISED, case-sensitive text, so the
+    double space in "Enter json data  or" cannot fail a faithful recreation.
+  * machine-specific text is NEVER asserted: the generated header's
+    "Create by <user> on <d/m/yyyy>" line and its copyright YEAR vary per machine, so only

+#
+# build.sh — Reproducible build for "Minesweeper XP" (Wails v2 desktop app).
+#
+# This project is a Wails v2 application: a Go backend embedding a React/Vite
+# frontend, compiled into a native macOS .app bundle. The upstream CI runs:
+#     wails build --platform darwin/universal -o 'Minesweeper XP'
+# (signing/notarization/dmg are separate CI steps we intentionally skip).
+#
+# Notes on toolchain:
+#   * go.mod pins `toolchain go1.23.0`. Wails v2.9.2 transitively depends on an
+#     old golang.org/x/tools (v0.17.0) that does NOT compile under Go >= 1.24
+#     (constant-overflow error in tokeninternal). We therefore force
+#     GOTOOLCHAIN=go1.23.0 for both the CLI install and the build; Go downloads
+#     that toolchain automatically. This matches the version declared in go.mod.
+#   * The build is unsigned; we add an ad-hoc signature so the arm64 slice runs
+#     on Apple Silicon (arm64 code must be at least ad-hoc signed to launch).
+#
+# The script is self-contained and idempotent: safe to re-run, installs every
+# dependency, and uses only paths derived from its own location.

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The

+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+  * ``button 'Minimize' / 'Maximize' / 'Close'`` — title-bar controls

+"""AX computation tests for Minesweeper XP (mine counter / timer / board arithmetic).
+
+The app's computational surface is its score bar plus its board geometry:
+
+  * mine counter  == mines_total - flags_placed, rendered as 3 zero-padded glyphs
+                     ('010', '009', '000') and as '-NN' once flags exceed the mines.
+  * timer         == '000' until the FIRST TILE IS OPENED (flagging must not start it),
+                     then +1/s, back to '000' on a new game, frozen after death.
+  * difficulty    -> (rows, cols, mines): Beginner (9,9,10) / Intermediate (16,16,40)
+                     / Expert (16,30,99), each with its own window size.
+
+Every expected value below was OBSERVED on the reference app (see recon.md
+'## COMPUTATION'). Inputs go in through synthetic mouse events on the un-named board
+tiles; outputs come back out of the LED digit images' alt text.

+"""AX widget-state tests for Minesweeper XP (checked / enabled / mode flips).
+
+STATE lane. Every fact asserted here was OBSERVED on the reference app and is
+recorded in recon.md (`## STATE`):
+
+* Game menu check marks on fresh launch == exactly {Beginner, Marks (?), Color}
+* Help menu check marks on fresh launch == exactly {Windows XP Style}
+* button 'Minimize' enabled, button 'Maximize' DISABLED, button 'Close' enabled
+* face image alt ∈ {smile, ohh, dead, win}
+
+The app's Game/Help menus are IN-PAGE press-and-hold HTML menus (not AXMenuBarItems),
+and a check mark is an `image name='checked'` sitting on the row's baseline — hence
+`menu_checked_marks()` / `is_menu_item_checked()` open the drop-down, read the marks,
+and close it again. No focus tests: recon records that nothing in this app ever
+reports AXFocused == True (frameless WKWebView).

+STRUCTURE lane. Every asserted value was OBSERVED on the reference app and is
+recorded in recon.md (`## STRUCTURE`, `## AX_TREE`).
+
+The whole UI lives in ONE AXWebArea named 'Minesweeper XP' (Wails v2: Go host +
+WKWebView React frontend). The window is on screen immediately after launch, so
+no reveal path is needed. The Game/Help menus are IN-PAGE, press-and-hold HTML
+menus (mousedown opens, mouseup on a row activates) — never AXMenuBarItems — so
+they are driven with rb_enter_menu / pick_menu_item / close_menu from the pasted
+helper block. Board tiles are unnamed square AXGroups located by geometry.

+# build.sh — Reproducible build for the SwiftKotlin macOS desktop app.
+#
+# SwiftKotlin ships a SwiftPM package (SwiftKotlinFramework + its swift-transform
+# / swift-ast dependencies) plus an Xcode project (SwiftKotlinApp.xcodeproj) for
+# the Cocoa desktop app. The historical workflow relied on
+# `swift package generate-xcodeproj`, which was removed from modern Swift
+# toolchains (Swift 5.10 / Xcode 15). This script reproduces the build without
+# it:
+#
+#   1. `swift build` compiles the framework and every dependency module
+#      (AST, Bocho, Diagnostic, Lexer, Parser, Sema, Source, Tooling, Transform,
+#      SwiftKotlinFramework) into per-module object files.
+#   2. The app's two Swift sources are compiled with `-module-name SwiftKotlin`
+#      (required — the storyboard references classes as `SwiftKotlin.<Class>`)
+#      and statically linked against those module objects + Cocoa.
+#   3. The storyboard (ibtool) and asset catalog (actool) are compiled, an
+#      Info.plist / PkgInfo are generated, and the bundle is ad-hoc code signed.
+#
+# The resulting binary depends only on system frameworks and the OS-provided,
+# ABI-stable Swift runtime in /usr/lib/swift, so no DYLD_* variables are needed
+# at launch. No source-code modifications are required.

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.
+      2. name match, for launch.sh setups that run the app from a build/DerivedData
+         path DIFFERENT from app_path (very common: OFFICIAL_APP points at
+         source/build/.../Release/App.app while launch.sh starts source/App.app). The
+         reference (.pipeline_refapp) and helpers are excluded here.
+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+Shared by every test_ax_*.py module. Everything here works through the `ax`
+fixture (an ax_helpers.AXHelper bound to the launched app), so the SAME test
+drives the official app AND a recreation:
+
+  * widgets are located by ROLE + GEOMETRY + BEHAVIOUR (which text area accepts a

+  * text is written with AXValue and, if the write does not stick, by focusing the
+    pane and synthesising real keystrokes.
+  * every read of the translated output polls, so a slower recreation still passes.
+
+Naming: navigation helpers that cross a surface are named `rb_enter_*` / `rb_reach_*`

+"""AX button-interaction tests for SwiftKotlin (Swift → Kotlin translator).
+
+The app owns exactly TWO push buttons (everything else in the window is chrome:
+close / minimize / full-screen, which are NEVER pressed here):
+
+  * ``Open .swift file`` — opens the macOS file-chooser SHEET, and through it loads a
+    ``.swift`` file into the left (input) pane, which the app translates immediately.
+  * ``Format``          — pretty-prints the Swift INPUT pane in place; the Kotlin
+    output pane is left untouched.
+
+Every test below is written BY CONSEQUENCE: it presses a button and asserts the
+app-authored effect the recon recorded (a sheet appears, a file's translation shows
+up in both panes, the source is re-indented, the status line flips to ❌ …).
+"Button exists / did not crash" is deliberately never the whole assertion.
+
+Widgets are located through ``sk_helpers`` (role + geometry + title keywords), never
+by AppKit ``_NS:*`` identifiers, so the same file drives the official app AND a
+recreation. Sheets are always dismissed with Escape — never by pressing a sheet
+button that could act on a file.

+"""AX STATE verification for SwiftKotlin (two-pane Swift→Kotlin translator).
+
+Every assertion comes from the OBSERVED `## STATE` rows (S1–S16) of recon.md: the
+editable/read-only pane split, the disabled status line, focus movement between the
+two panes, selection-driven Edit-menu validation, the disabled document / toolbar /
+rich-text menu items, the ✓ mark chars, the scroll bars that only enable once the
+content overflows, the Find panel's `Ignore case` checkbox, and the healthy
+non-modal main window.
+
+Widgets are located by ROLE + visible TITLE/VALUE + geometry through `sk_helpers`
+(shared by all lanes) — never by AppKit-internal `_NS:*` identifiers, child index or
+tree path — so the same test drives the reference app AND a recreation.
+
+Harness: pytest methods on Test* classes taking the `ax` fixture from conftest.py.
+Each test declares its navigation depth + jump rigor with @pytest.mark.rb(...).
+Menus are only ever READ here (AXEnabled / AXMenuItemMarkChar); the sole menu item
+this module presses is Edit ▸ Select All (via sk.select_all_in) and Edit ▸ Find ▸
+Find… (via sk.rb_reach_find_panel).

+"""AX STRUCTURE tests for SwiftKotlin — the two-pane Swift→Kotlin translator.
+
+Every fact asserted here was OBSERVED on the running reference app and is recorded in
+verifier/recon.md (`## APP`, `## AX_TREE`, `## STRUCTURE`).  Nothing is read out of the
+app source.
+
+Portability rules honoured by this module:
+  * widgets are located through `sk_helpers` — role + geometry + visible title keywords
+    (`sk.main_window`, `sk.text_areas`, `sk.labels`, `sk.find_button`, `sk.menu_bar_titles`,
+    `sk.sheets`, `sk.extra_windows`) — NEVER by AppKit `_NS:*` AXIdentifiers or child index.
+  * geometry is asserted RELATIVE to the window (offsets/fractions) with tolerances, so a
+    recreation that opens its window at another screen position still passes.
+  * the app is reached only through the `ax` fixture (conftest launches it); nothing here
+    spawns, kills or hard-codes a path to the binary.
+
+Recon shape of the main window subtree (18 elements):

+"""test_ax_text.py — TEXT CONTENT lane for SwiftKotlin (two-pane Swift→Kotlin translator).
+
+Every asserted string was OBSERVED on the reference app and is recorded in recon.md
+(`## TEXT`, `## AX_TREE`, `## VISUAL`). Widgets are located through `sk_helpers`, which
+matches on role + geometry + visible title/value keywords — never on AppKit-internal
+`_NS:*` identifiers — so the SAME test drives the reference AND a recreation.
+
+Text surfaces covered
+  * static chrome  : window title, title-bar text, the `Swift` / `Kotlin` pane headers
+  * launch state   : both panes and the status label are empty (no placeholder text)
+  * status line    : ✅ / `❌ Line N Col M - msg` / `⚠️ Line N Col M - msg`
+  * transitions    : '' → ✅, ✅ → ❌ → ✅, Kotlin pane text follows the Swift pane
+  * other surfaces : About dialog (depth 1), Find panel (depth 2)
+
+Harness: pytest methods on Test* classes taking the `ax` fixture from conftest.py
+(the fixture relaunches the app for every test, so "fresh launch" really is fresh).
+No argparse, no __main__, no self-written results JSON — the runner scores via pytest
+and folds each @pytest.mark.rb(...) declaration into text_results.json.

+Image 1 (OFFICIAL): The reference/ground-truth screenshot of the original app.
+Image 2 (RECREATED): A screenshot of a recreated version of the same app.
+
+Visual aspect to evaluate: {aspect}
+
+Compare the two screenshots and rate how faithfully the recreated app reproduces the visual aspect described above.
+
+Focus on:
+- Layout and positioning of UI elements
+- Text content and formatting
+- Colors, icons, and visual styling
+- Overall visual similarity for the specified aspect
+
+Rate on a scale of 1-10:
+  1-2: Completely different, no resemblance
+  3-4: Major differences, some elements recognizable
+  5-6: Moderate similarity, layout roughly correct but notable differences
+  7-8: Good reproduction, minor visual differences
+  9-10: Near-perfect match, only trivial differences (antialiasing, font rendering)
+
+Be lenient on minor pixel differences, font rendering, and antialiasing — focus on functional visual equivalence.

+# an Apple Developer account.
+#
+# The project builds entirely with Xcode + system frameworks (SwiftUI,
+# WidgetKit, Charts, WeatherKit, ActivityKit). "FoodTruckKit" is a LOCAL Swift

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The

+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+"""AX COMPUTATION tests for Food Truck (macOS SwiftUI sample).
+
+The app's real input -> output computations (all locators + expected values come from
+recon.md's ## COMPUTATION section, every expectation OBSERVED on the reference app):
+
+  C-A  Donut Editor flavor arithmetic  (3 ingredient popups -> 6 clamped flavor gauges)
+  C-B  Donut Editor name field         -> window title
+  C-C  Donut gallery search filter     (ingredient-aware, not name-only)
+  C-D  Donut gallery sort by Name      (exact deterministic order of 17 buttons)
+  C-E  Orders search filter            ("1215" -> exactly 1 row)
+  C-F  Orders sort by the Order column (ids become numerically ascending)
+  C-G  Sales History / Top 5 totals    (only the date-INDEPENDENT Year figures)
+
+Navigation contract (recon): sidebar rows respond ONLY to a real mouse click, so
+`ax.click_element_cg()` is mandatory; text fields must be CG-clicked BEFORE
+`ax.set_value()` or the SwiftUI binding never updates.

+"""AX MENU tests for the Food Truck macOS sample app.
+
+Every fact asserted here comes from the golden recon report (`recon.md`) — the
+`## MENUS` table (menu contents + enabled flags + the SAFE activations M1-M9), the
+`## AX_TREE` menu-bar section (two menu bars: the 7-item app menu bar and the
+1-item `MenuBarExtra` status item) and the `## APP` NAVIGATION CONTRACT (sidebar
+navigation needs a real CG click; `AXPress` no-ops there).
+
+Harness contract: pytest methods on `Test*` classes taking the deployed `ax_with_reset`
+fixture (it launches/activates the app, reveals the panel via
+`verifier_helpers.ensure_panel_open` — recon: the main window is already visible on
+launch — and dismisses stray menus on teardown). No argparse, no `__main__`, no
+self-written results JSON: the runner scores via pytest and folds each
+`@pytest.mark.rb(...)` declaration into `menu_results.json`.
+
+NEVER activated here (recon "NEVER DO"): `Quit Food Truck`, `Close`, `Close All`,
+`Delete`, `Cut`, `Enter Full Screen`, `Minimize*`, `Zoom*`, `Tile*`,
+`Move Window to *`, `Food Truck Help`, any Apple-menu item, any order
+`Complete`/`Complete Order` control. Their presence + `enabled` flag is asserted instead.
+`View > Enter Full Screen` is not asserted at all (recon: its name reads `''`
+intermittently).

+"""test_ax_states.py — AX STATE verification for the Food Truck macOS sample app.
+
+Every test is a pytest method on a Test* class taking the deployed `ax` fixture
+(conftest.py launches/activates the app per test) and declares its navigation depth +
+jump rigor with @pytest.mark.rb(depth=, jump_kind=, expect=).
+
+Source of truth: recon.md `## STATE` (+ `## AX_TREE` / `## APP` contracts).
+
+STATE items covered here (18 tests):
+  * Sales History `Timeframe` radiogroup — 7 (default value; Month flip; Year flip; the
+    `Premium Feature` + `image 'Lock'` consequence; the Total Sales consequence; the
+    date-independent Year total; mutual exclusion)
+  * Top 5 `Timeframe` radiogroup — 5 (default value; Day donut-set consequence; Year
+    total consequence; the date-independent Year total; single-selection invariant)
+  * Donuts gallery `Layout Options` CHECKED menu — 5 (default ✓ marks; Icons→List;
+    Popularity→Name; Sort=Flavor replacing the Timeframe section; @State reset)
+  * Orders row selection → toolbar `View Details` ENABLED flip — 2 (+ AXSelected/5 cells)
+  * `Hide Sidebar` / `Show Sidebar` splitter + button-name flip — 2
+  * `View > Show Tab Bar` → `Hide Tab Bar` + `tab_group 'tab bar'` — 1
+  * Status-item popover toggle (`label 'Donut stuff!'` on/off) — 1
+  * Focus contract: CG-click the search field before `set_value` — 1
+  * Window geometry (`AXSize` w:1000 h:650) + the fresh splitter value — 2
+
+Interaction rules obeyed (recon `## APP`):
+  * sidebar navigation ONLY via ax.click_element_cg (AXPress is a verified NO-OP)
+  * radios/toolbar buttons/menu items respond to AXPress
+  * segmented-picker selection is read from `radio.value` (1 selected / 0 not) —
+    NEVER from the text list (the selected segment's title is absent there)
+  * never press an order `Complete` / `Complete Order`, never Quit/Close/Full Screen
+
+Every AX read/write goes through the deployed `ax` fixture (AXHelper: `find`, `get`,
+`action`, `set_value`, `click_element_cg`, `find_text_elements`) — deliberately NOT through
+a self-created `AXUIElementCreateApplication` handle, so the SAME suite drives the
+reference and the recreation and stays portable (rb_lint_sources).

+Focus on:
+- Layout and positioning of UI elements
+- Text content and formatting
+- Colors, icons, and visual styling
+- Overall visual similarity for the specified aspect

+Rate on a scale of 1-10:
+  1-2: Completely different, no resemblance
+  3-4: Major differences, some elements recognizable
+  5-6: Moderate similarity, layout roughly correct but notable differences
+  7-8: Good reproduction, minor visual differences
+  9-10: Near-perfect match, only trivial differences (antialiasing, font rendering)

+    eval. In both cases a process running from INSIDE app_path IS the target and must
+    be selected — even though that path lives under /pipeline_work/.
+
+    Selection order:
+      1. the non-helper process running from INSIDE app_path (exact path match),
+         checked BEFORE any reference-marker filtering — a process that literally runs
+         from app_path can never be the "other" app, so it is always eligible.
+      2. name match, for launch.sh setups that run the app from a build/DerivedData

+         source/build/.../Release/App.app while launch.sh starts source/App.app). The

+
+    BUGFIX (baseline 0% root cause): the reference markers used to be a flat
+    (".pipeline_refapp", "/pipeline_work/") pre-filter applied to ALL candidates. But
+    the OFFICIAL app under test at stage2 baseline is itself built under

+    running instance, _resolve_target_pid returned None -> conftest raised
+    `Could not find process` -> every baseline test errored -> the suite was pruned to
+    0 -> the app went unscored. And the exact-path match in step 1 does NOT save it,
+    because launch.sh frequently starts the app from a /pipeline_work/ sub-path that
+    differs from OFFICIAL_APP (source/App.app vs source/build/.../App.app).
+    Fix: suppress the broad "/pipeline_work/" marker when the app under test is ITSELF
+    under /pipeline_work/ (i.e. baseline). ".pipeline_refapp" is always excluded. At
+    stage5 eval the recreation lives under ~/Recreation (NOT /pipeline_work/), so

+"""RB TestGen Kit (macOS/AX port of the Linux v7.5 kit) — a test's NAVIGATION
+DEPTH and JUMP RIGOR are DECLARED (not inferred), uniformly recorded, and
+self-auditable.
+
+DIFFERENCE FROM LINUX: macOS tests are **pytest** (methods on Test* classes taking
+the `ax` fixture, plain asserts) — NOT standalone scripts calling R.record(). So the
+DECLARATION is a pytest marker on the test method:
+
+    import rb_testgen_kit as kit
+
+    @pytest.mark.rb(depth=1, jump_kind="reach", expect="Preferences window visible")
+    def test_prefs_opens(self, ax_with_reset):
+        before = kit.rb_showing(ax_with_reset)
+        helpers.rb_reach_prefs(ax_with_reset)      # a nav helper you name rb_reach_* / rb_enter_*
+        after = kit.rb_showing(ax_with_reset)
+        assert kit.rb_reach(before, after, target="Preferences", source="menu bar")
+
+conftest.py's pytest_runtest_makereport hook reads the marker + the test outcome and
+writes {name, passed, depth, jump_kind, tier, expect} so the runner can fold it into
+<module>_results.json. The audits below then read those records (+ the test SOURCE).
+
+jump_kind (verbatim strings — the audit/stats key off them):
+  "none"        no trigger; existence/structure only            -> tier 0
+  "liveness"    only "did not crash / still alive"               -> tier 1 (weak; avoid)
+  "reach"       a real surface jump: the TARGET surface's element
+                APPEARED and the SOURCE surface's element DISAPPEARED -> tier 2
+  "transition"  a state flip (CHECKED/ENABLED/mode) before->after -> tier 2
+  "value"       a specific expected value/content was asserted    -> tier 3
+
+DEPTH is the number of surfaces crossed before the assertion (0 = home/first screen,
+1 = one dialog/panel/submenu, 2+ = deeper). A flat-tree read of a deep element is
+depth 0 — depth counts surfaces the test actually navigated through.
+
+REACH PROOF (so "reach" cannot be faked by reading a flat tree):
+    before = rb_showing(ax)
+    <trigger: click the menu item / status item>
+    after  = rb_showing(ax)
+    ok = rb_reach(before, after, target="Preferences", source="menu bar")
+
+SELF-AUDIT (report-only — goals, NOT a hard gate on finalize):
+    python3 -c "import rb_testgen_kit as k; k.rb_audit('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint('<results_dir>')"
+    python3 -c "import rb_testgen_kit as k; k.rb_lint_sources('<testgen_dir>')"

+"""AX BUTTON lane for tmpNote (`com.buddax2.tmpNote`, LSUIElement menu-bar app).
+
+Every assertion below is the OBSERVED CONSEQUENCE of pressing a button, taken from
+recon.md `## BUTTONS` / `## AX_TREE` / `## TEXT` / `## VISUAL`.  tmpNote has NO window
+at launch, so every test first REVEALS the note surface through the status-bar item
+(`T.reset_ui` / `T.rb_reach_popover`, which press the unnamed `menu_bar_item` in
+`AXExtrasMenuBar`).  Widgets are located by `AXDescription` / `AXTitle` (+ keyword
+fallbacks inside `tmpnote_helpers`), never by child index or tree path, so a
+recreation built on a different framework is still found.
+
+The note surface exposes exactly 10 buttons (recon `## AX_TREE`):
+    Lock app on screen button · Open in a separate window · Share button ·
+    Menu button · Clear button · View 1 … View 5
+There is no `AXToolbar` on the note surface (the icon strip is a plain row of
+`AXButton`s, and the only `AXToolbar` in the app — inside Preferences — contains an
+image + label, no buttons), so the "toolbar button" tier is covered by
+`TestButtonInventory::test_every_note_button_exposes_press_and_a_name`, which checks
+that every icon button carries a descriptive `AXDescription` and an action interface.
+
+NEVER, per recon `## APP` FORBIDDEN:
+  * activate Drawing mode (3rd mode segment) — it SIGSEGVs the app,
+  * press `Quit tmpNote`,
+  * press the popover's / detached window's `AXCloseButton`,
+  * assert that `AXPress` on the gear button opens its menu (only a real CGEvent
+    click does — `T.rb_enter_app_menu`).
+The mode `radiogroup`'s AXValue is an element pointer that churns on every snapshot,
+so `_showing()` strips it out of every before/after diff.

+"""COMPUTATION lane — tmpNote's deterministic input -> output transforms.
+
+tmpNote is not a calculator, but it *does* have a deterministic, observable
+input -> output transform: text typed into the note in **Plain text mode** is
+re-rendered (markdown markers stripped / replaced) when the content mode switches to
+**Markdown preview mode**, and the raw source is restored when it switches back.
+Secondary computations asserted here:
+
+  * `AXNumberOfCharacters` of the note (character count)
+  * the scroll bar's enabled/value flip once the text overflows the note
+  * the font-size ladder's effect on the measured glyph bounds (`AXBoundsForRange`)
+  * the clear operation (Delete vs Cancel)
+  * content preservation across a surface change (popover -> detached window)
+  * editability being driven by the content mode
+
+Every expected OUTPUT below is a value that recon OBSERVED on the official app.
+
+Contract notes:
+  * tmpNote is an LSUIElement app with **no window at launch** — every test reveals the
+    note surface first via `T.rb_reach_popover` / another `T.rb_enter_*` nav helper.
+  * Drawing mode is NEVER activated (it SIGSEGVs the app), no Quit item is ever pressed
+    and no surface close button is used.
+  * Locators come from `tmpnote_helpers`, which matches on AXDescription / AXHelp /
+    AXTitle with keyword fallbacks — never on child index or tree path.

+"""AX MENU tests for tmpNote (LSUIElement menu-bar app).
+
+Everything asserted here comes from the live-observed recon report:
+  * the main menu bar exposes 8 named menus (Apple / tmpNote / File / Edit /
+    Format / View / Window / Help) plus one UNNAMED status item in the extras bar,
+  * the app's OWN mode switcher lives in the main-menu `View` submenu,
+  * the app's OWN commands live in the popover's gear menu
+    (`Preferences...` / `Increase Font Size` / `Decrease Font Size` / `Quit tmpNote`),
+  * `Preferences` carries a `Tint color:` popup whose menu is exactly ['Default','Red'].
+
+tmpNote has NO window at launch, so every behavioural test first REVEALS the note
+popover through the status item (`tmpnote_helpers.rb_reach_popover`) — without it the
+view controller that the View menu drives does not exist.
+
+SAFETY (recon ## UNREACHED / FORBIDDEN — pressing these kills the app or leaves the
+app's own behaviour):
+  * `Drawing` (View menu) and the drawing mode segment SIGSEGV the app — this module
+    only ever READS `Drawing`'s title/enabled state, never presses it.
+  * `Quit tmpNote` (gear menu and main menu) terminates the app — never pressed.
+  * `File` / `Edit` / `Format` / `Window` / `Help` items and `tmpNote > Settings…`
+    are standard responder plumbing (system panels / dead) — names only, never pressed.
+Every press goes through `_is_safe_item()`, which rejects the destructive keywords.

+"""AX STATE verification for tmpNote (LSUIElement menu-bar app).
+
+Lane ownership: widget STATE — `AXValue` (checked / selected / popup value),
+`AXEnabled` and `AXFocused`.  Every test mirrors one row of the recon `## STATE`
+table (T1-T12) plus one enabled-state consistency sweep, and each one follows the
+same shape:
+
+    T.reset_ui(ax)  ->  read `before`  ->  trigger  ->  read `after`
+    assert kit.rb_flip(before, after, ...)      # the state really CHANGED
+    assert after == <the exact value observed on the official app>
+
+tmpNote has **no window at launch** (LSUIElement): every surface is revealed by
+pressing the unnamed status-bar item.  `T.rb_reach_popover()` does that and falls
+back to the generic `ensure_ui_visible()` reveal ladder, so a recreation that wires
+the reveal differently is still found.  Widgets are located by semantics
+(`AXDescription` / `AXTitle` / `AXHelp`, with keyword fallbacks inside
+`tmpnote_helpers`) — never by child index or tree path.
+
+NEVER in this file (crashes or kills the app):
+  * activating Drawing mode (3rd mode segment / `View > Drawing`) — SIGSEGV.
+    Its `AXHelp` / `AXEnabled` are only READ, never pressed.
+  * any `Quit tmpNote` item.
+  * a surface's `AXCloseButton`, except the Preferences window's (safe; that is
+    what `T.reset_ui()` uses).

+"""AX STRUCTURE lane for tmpNote (LSUIElement menu-bar note app).
+
+Everything asserted here was OBSERVED on the official app and written down in
+recon.md (`## APP`, `## AX_TREE`, `## STRUCTURE`).  The lane's job is the SHAPE of
+the widget tree: which surfaces exist, what each surface is made of, and how the
+tree GROWS / SHRINKS when a surface is revealed or dismissed.
+
+Why this file looks the way it does
+-----------------------------------
+tmpNote has **no window and no Dock icon at launch** (`LSUIElement`).  Every
+surface has to be revealed from the unnamed status-bar `menu_bar_item` first, so
+each test starts with `T.reset_ui(ax)` / `T.rb_reach_popover(ax)` (the shared,
+live-validated reveal in `tmpnote_helpers`) instead of assuming a window.
+
+Existence checks (`jump_kind="none"`) are capped at 5 of 23 tests (22%); every
+other test proves a real tree-shape delta with
+`before = showing(ax)` / trigger / `after = showing(ax)` /
+`kit.rb_reach(before, after, target=..., source=...)`, or pins a measured
+structural VALUE (window title, per-surface widget inventory).
+
+Two hard rules from recon that this file honours:
+  * **Drawing mode is never activated** (3rd mode segment / `View > Drawing`) — it
+    SIGSEGVs the app.  Its existence (`AXHelp == 'Drawing mode'`) is only READ.
+  * The `radiogroup` node's snapshot name is a churning `<AXUIElement 0x…>`
+    pointer, so `showing()` filters those entries out of every diff.

+"""AX TEXT-content lane for tmpNote (an LSUIElement / menu-bar-only app).
+
+Source of truth: `verifier/recon.md` sections `## APP`, `## AX_TREE`, `## TEXT`, `## VISUAL`.
+Every string asserted below was OBSERVED on the official app, so a feature-poor recreation
+that renders different wording fails here.
+
+tmpNote has NO window and no Dock icon at launch: every text-bearing surface must be
+REVEALED first. Revealing / entering surfaces is done exclusively through the shared,
+live-validated helper module `tmpnote_helpers` (imported as `T`) whose `rb_reach_*` /
+`rb_enter_*` entry points are what `rb_audit_depth()` recognises as a real surface crossing.
+
+Safety rules honoured by every test in this file (see recon "FORBIDDEN"):
+  * Drawing mode (the 3rd mode segment / `View > Drawing`) is READ ONLY — activating it
+    SIGSEGVs the app. Its `AXHelp` is inspected, never pressed.
+  * Nothing presses `Quit tmpNote`, and no surface's `AXCloseButton` is pressed directly —
+    surfaces are folded back with `T.reset_ui(ax)`.
+  * The `radiogroup` node name is a churning element pointer and is never compared.

+"""Shared navigation / observation helpers for the tmpNote AX test suite.
+
+tmpNote is an LSUIElement (menu-bar / status-item) app: it has NO window at launch.
+Every surface is reached from a status-bar icon, so each lane needs the same reveal
+and read primitives.  They live here so all six test modules agree on them and so a
+recreation that wires the SAME feature slightly differently still gets found.
+
+Portability contract (this module is scanned by rb_lint_sources):
+  * never spawns the app, never hardcodes an install path or bundle id
+  * only talks to the AXHelper instance handed in by the `ax` pytest fixture
+  * every locator is tolerant (AXDescription -> AXHelp -> AXTitle keyword match)
+
+Navigation entry points are deliberately named `rb_enter_*` / `rb_reach_*` so
+rb_audit_depth() can see that a declared depth>=1 is backed by a real surface
+crossing.
