Checkpoint — Codex FIX7 Final Authority Seal N7/N8/P7

• Execution date: 2026-06-11 Asia/Ho_Chi_Minh
• Final status: CODEX_FIX7_FINAL_AUTHORITY_SEAL_REJECT
• Production mutation: NO
• N7/N8/P7 authored: NO / NO / NO

Decision

The supplied harnesses are internally consistent in secondary local reconstruction, but the final authority seal is rejected.

Blocking facts:

1. Required actual governed-KB rehearsal files are missing (404), including commands.sh, HASH_MANIFEST.txt, packet_tree.sha256, summary, exit-code, stdout, and stderr artifacts.
2. Direct adversarial probes prove fail-open acceptance of empty/non-hex/invalid N7, N8, and P7 values, empty report sets, and duplicate report records.
3. Proposed N6 active_corpus_sha256 is classified REHEARSAL, while the encoder performs no authority-provenance validation.

Protocol verdict

• AS-P1: PARTIALLY_CLOSED / FAIL
• AS-P2: CLOSED
• AS-P3: NOT_CLOSED
• AS-P4: NOT_CLOSED
