What this Tool does
Verify that a selected child custody chain preserves an exact parent prefix and adds exactly one canonical link bound to the parent head.
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 a parent and child Phase 75 custody-chain JSON. A valid extension must preserve the entire parent prefix and add exactly one link bound to the parent head.
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.
