What this Tool does
Compare same, changed, missing and extra deterministic archive records between two catalogs.
Offline query boundary
Phase 78 is a local exact-index/query authority only. A catalog match or absence is not a semantic interpretation, relevance ranking, ownership/authenticity proof, remote-origin proof, trusted timestamp, real-world chronology, legal chain-of-custody proof, compatibility decision, restore authorization, or live-save mutation authority. No remote search, account/cloud lookup, upload, signing/private-key operation or source-evidence embedding is performed.
Input contract
Choose two valid Phase 78 catalog JSON documents. Comparison uses exact archive-record and cryptographic identity sets only; neither catalog is treated as newer or authoritative.
Safe interpretation
Exact indexed equality can locate cryptographic or literal values already present in a deterministic local catalog. It cannot infer intent, meaning, relevance, authorship, provenance truth, chronology, ownership, origin or trust.
