Proof receipts and experimental rewrite lab
- Added visible Proof Receipt v2 results with exact SHA-256 fingerprints, capability states, and authorship left undetermined
- Added privacy-safe JSON downloads and copyable proof summaries without including source or cleaned text
- Added the same versioned proof contract to the single-scan API with accurate browser-local versus server generation labels
- Added an off-by-default local iterative rewrite experiment with one to three capped attempts
- Preserved the immutable original and rejected candidates that change numbers, URLs, or too much wording
- Added explicit inconclusive states, evaluator details, attempt evidence, and zero remote-model cost
- Published versioned experiment fixtures and prohibited provider-removal or authorship claims
