What this Tool does
Recompute a Phase 75 provenance receipt evidence identity and receipt ID to detect JSON tampering without consulting any external authority.
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 one Phase 75 provenance-receipt JSON. The Tool recomputes its canonical evidence identities and receipt ID without contacting an external registry.
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.
