What this Tool does
Verify whether one strictly revalidated Phase 79 report is present byte-for-byte in a valid Phase 80 casebook.
Offline review boundary
Phase 80 creates deterministic local review collections only. It does not establish semantic findings, annotations with authority, collaboration/account authority, authorship, ownership, authenticity, origin, chronology, legal custody, authoritative-copy status, compatibility, restore priority, trusted time, remote trust, signature validity or production acceptance.
Input contract
Choose one valid Phase 80 casebook plus one valid Phase 79 report. The source report is strictly revalidated before exact report-ID/document-digest membership comparison.
Safe interpretation
A valid casebook proves deterministic local grouping and exact cryptographic binding to revalidated Phase 79 reports. Report ordering is cryptographic, not chronological, and aggregate counts may overlap across reports.
