+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+# Screenplay Format Edge Cases
+
+48 original Fountain specimens in 24 contrast pairs — two near-identical inputs
+per pair, at the points where the Fountain syntax leaves a choice. In 17 pairs
+the one difference changes how the lines are classified. In the other 7 it
+changes the surface and the labels hold: a lowercase scene prefix, a cue
+extension, a non-Latin cue, escaped characters, a dual-dialogue caret, an inline
+note and centered-text markers.
+
+**Version:** 1.0.0 · **Maintainer:** Inkwell.
+
+Built by [Inkwell](https://www.inkwell.software/?utm_source=huggingface&utm_medium=referral&utm_campaign=observatory&utm_content=screenplay_format_edge_cases_card_home), the IDE for screenwriters.
+Paste Fountain into the [Fountain validator](https://www.inkwell.software/tools/fountain-validator?utm_source=huggingface&utm_medium=referral&utm_campaign=observatory&utm_content=screenplay_format_edge_cases_card_validator)
+to see the scenes, character cues, dialogue and action it recognizes.
+
+## What's included
+
+`data/cases.jsonl` holds all 48 records; `schema.json` is a JSON Schema for one
+record. Each record carries the Fountain input, its expected line-level element
+types, the contrast pair it belongs to, and a short rationale for the expected
+labels.
+
+## Provenance
+
+Every specimen is original Fountain written for Inkwell and released under
+CC0-1.0.
+
+## How the labels work
+
+The expected labels are line-level screenplay element types. A pair shares a
+`pair_id`, and `split_group` repeats it: keep both variants of a pair in the same
+split, because the point of a pair is the single difference between its two
+inputs.
+
+Forty-two of the 48 specimens fall inside the subset a demonstration Fountain
+parser implements, and `supported_by_demo` marks which. The other six use dual
+dialogue, a note, boneyard, a section, lyrics and centered text — valid Fountain
+that the demonstration exporter stops on rather than guessing. The flag records
+one implementation's coverage.
+
+Two more things the labels assume: an FDX paragraph can group adjacent action or
+dialogue lines, so a paragraph count can differ from the line-level label count;
+and a forced-element marker (`!`, `@`, `.`, `>`) is syntax, not rendered text.
+
+## What it's for
+
+Teaching the syntax contrasts, building regression tests, and watching which
+single edit changes how a line is classified. Extend it with your own cases as
+your parser grows.
+
+## Load the records
+
+```python
+from datasets import load_dataset
+cases = load_dataset("Inkwell-Software/screenplay-format-edge-cases", split="test")
+print(cases[0])
+```
+
+## Citation
+
+Cite "Inkwell, Screenplay Format Edge Cases, version 1.0.0"; the machine-readable
+form is in [`CITATION.cff`](./CITATION.cff).
+
+## Maintenance
+
+Open a discussion with the case ID, the expected behavior, the observed behavior,
+and the relevant part of the [Fountain spec](https://fountain.io/syntax/). A
+change to expected labels is a version increment and a changelog entry.
