What this Tool does
Report same-path content changes and unchanged members between explicit before and after evidence sets using SHA-256 and byte length.
Evidence boundary
Phase 75 is a local evidence-recording layer. SHA-256 binds selected bytes, paths, declarations and chain links, but no surface proves legal chain of custody, creator identity, account ownership, authenticity, trusted timestamp, remote/cloud origin, real-world chronology, platform compatibility or semantic save validity. No digital signature, certificate, private key, remote registry, account access, upload, restore or file mutation is performed.
Input contract
Select explicit before and after local evidence sets. Phase 75 reports exact SHA-256/path/size differences and unambiguous renamed-copy candidates without asserting cause, actor or chronology.
Safe interpretation
Use these receipts to preserve deterministic local evidence and comparison history. A hash-bound label records exactly what was declared; it does not independently establish the identity of the declarant, a trusted timestamp, remote source, ownership, or legal custody.
