Current State — Codex Recheck 9 V3 FIX7 Packet Authority Blocked

Status: CODEX_RECHECK_9_V3_AUTHORITY_BLOCKED
Production mutation: NO
Engineering evidence: PASS
N7/N8/P7: NOT SEALED
Blueprint approval: NOT AUTHORIZED

Codex independently fresh-fetched and reconstructed Packet V3. Tree hash b95df0a5d2f41f80bea0cef8621c1f8bb0f6b49a40175116418494ed4141ca6d; 13-gate RERUN PASS; manifest verify observed six real CLI runs; black-box suite 10/10; fail-open regression 6/6; adversarial suite 25/25.

The exact V2 fail-open/laundering attack is now blocked: a copied SUT mutated from sys.exit(4) to sys.exit(0) made missing-doc CLI exit 0, but V3 --emit, --verify, RERUN, black-box suite, and adversarial suite all failed nonzero. R9-B6, Article 13, and Article 14 pass. No engineering/hardcode defect remains in the reviewed V3 scope.

Canonicalizer rev3 identity is verified as candidate: revision 3, 38756 UTF-8 bytes, SHA-256 49c386a9b9666c09786fc4f89bc79776b6046eaee6f4da6d8537d2c753b734d0.

Final seal/approval remains authority-blocked only: N7 needs authorized sealed approval-event inputs; N8 is Codex-authored after the authority event; P7 needs authorized re-seal; owner standing do-not-approve remains. FIX7 implementation and all prohibited runtime actions remain blocked.
