The current package conclusion is +that generic SHA-style preimage search does not gain more than the known +Grover-style square-root speedup, and that resource costs dominate long before +full-round attack relevance. + +## Why It Exists + +The project is useful because it draws a clean boundary between: + +- invariant-preserving quantum models, +- braid compilation and logical-qubit accounting, +- constraint/proof-directed search, +- and real cryptanalytic claims that require much stronger evidence. + +The goal is not hype. The goal is a falsifiable research artifact that can be +audited, extended, rejected, or archived based on explicit gates. + +## Package Status + +Version `1.0.1` is a staged research release.
