00 — T1 FIX7 Final Short-Review After CP-06 Hash Micro-Patch — Readme First

Date: 2026-06-08 Reviewer: T1 (production Agent for Agent Data) Mode: READ-ONLY production / AUTHOR_MODE_ONLY. No production DB/role/grant/trigger/function/scheduler/UI mutation; no DB object creation; no live SQL; no manifest activation; no ownership/ACL change; no permit; no Stage 2.6B; no REAL_RUN; no QT001 apply; no Codex-doc edit. KB review artifacts only.

Scope

Final short-review of Codex's CP-06 hash micro-patch (codex-fix7-cp06-hash-micro-patch-from-t1-proposals-2026-06-07/00..06), which applied T1's four prior proposals P-01..P-04 from t1-fix7-rp-corrected-design-short-review-2026-06-07/14. Four narrow items + non-regression. Old issues were NOT reopened — the patch introduces no new contradiction.

Headline

DESIGN_READY_FOR_CODEX_FINAL_APPROVAL. All four proposals verified against the real runtime-evidence DDL (codex-fix7-design-correction-…/02 rev 2). The single FIX7 acceptance gate — "H04/H05/H02 byte-implementable; every sub-payload key resolves to a named table.column" — is now MET. Zero blocking proposals remain.

What was verified (one line each)

• P-01: H04 evidence hashes deref evidence_registry.artifact_sha256 via the real NOT NULL reviewer_evidence_id/binding_evidence_id FKs. P01_VERIFIED.
• P-02: H04_SCOPE_V1 = exactly 8 keys, all real NOT NULL signoff_binding columns. P02_VERIFIED.
• P-03: H05 measurements/artifacts + H02 capability-hashes/post-activation-state membership + PK-terminated total orders pinned against real columns. P03_VERIFIED.
• P-04: every extra index fails OBJECT_AUTHORITY_IMMUTABLE; legitimize only via a new sealed #20 manifest version. P04_VERIFIED.
• Non-regression: exactly 27 authority surfaces; 11 non-authority runtime-evidence tables; 0 new gates; 0 new hash contracts; hard blocks intact. NON_REGRESSION_VERIFIED.
