What this Tool does
Compare exact casebook/report/catalog/operation identifier-set differences between two valid Phase 81 matrices.
Offline review boundary
Phase 81 creates deterministic local exact-identifier relationship matrices only. It does not establish semantic similarity, duplicate evidence, shared origin, causality, chronology, relevance, collaboration/account authority, authorship, ownership, authenticity, legal custody, authoritative-copy status, compatibility, restore priority, trusted time, remote trust, signature validity or production acceptance.
Input contract
Choose two valid Phase 81 matrices. Comparison reports exact identifier-set differences only; side order is not chronology, trust or authority.
Safe interpretation
A valid matrix proves deterministic local cross-indexing of exact identifiers derived from strictly revalidated Phase 80 casebooks. Identifier co-occurrence is cryptographic relationship evidence only and is not semantic similarity, chronology, shared origin, duplication, trust or authority.
