OrthoDrift 0.1.0

OrthoDrift 0.1.0 is the first complete deterministic vertical slice.

Highlights:

• strict, bounded, versioned case and experiment-run contracts
• typed grapheme provenance and registered rule validation
• deterministic Unicode-word BM25 retrieval and globally minimal supplied-edit proofs
• exact runtime/engine replay verification
• standalone verified offline report
• 13 source-bound CLI, UI, GIF, chart, diagram, artifact, and manifest evidence files
• hash-locked Python/browser environments and read-only visual drift verification
• tested on exact CPython 3.11.15, 3.12.13, 3.13.14, and 3.14.6
• CodeQL Actions/Python, Dependabot, secret scanning, push protection, and protected linear main

Verified synthetic result: target rank 1 → 2; global minimum 1/3 edits, U+015E → U+0053 U+0327.

Claim boundary: this is a synthetic lexical counterexample, not a broad multilingual benchmark, native-language review, or dense-retrieval evaluation.
