What this Tool does
Fail closed if an interchange bundle repeats an exact local artifact path or contains a path outside the strict relative-path contract.
Interchange boundary
Phase 76 is a portable local JSON interchange and consistency layer. SHA-256 proves only equality to the canonical bytes calculated locally. It is not a digital signature, trusted timestamp, ownership/authenticity proof, remote-registry attestation, legal chain of custody, account/provider identity, cloud origin, game compatibility or semantic save-validity authority. No source save bytes are embedded and no source artifact or save is modified.
Input contract
Choose one Phase 76 interchange bundle JSON. Every manifest row, embedded canonical artifact digest, manifest SHA-256 and bundle ID is recomputed locally; supported Phase 75 receipts/chains are revalidated canonically.
Safe interpretation
Use Phase 76 to move and compare deterministic local evidence JSON without weakening the Phase 75 authority boundary. Hash continuity is useful evidence of exact equality, but it does not authenticate a person, service, device, timestamp, origin or legal custody event.
