Checkpoint — Codex FIX7 Authority Seal Approval Lane

• Date: 2026-06-10
• Status: CODEX_FIX7_AUTHORITY_REJECT
• Host: CODEX
• Production mutation: NO
• N7/N8/P7 authored: NO / NO / NO

Engineering PASS remains valid: Packet V3 tree b95df0a5d2f41f80bea0cef8621c1f8bb0f6b49a40175116418494ed4141ca6d; canonicalizer revision 3 / 38756 UTF-8 bytes / SHA-256 49c386a9b9666c09786fc4f89bc79776b6046eaee6f4da6d8537d2c753b734d0; Article 13/14 PASS and no reviewed-scope hardcode defect.

Seal rejected because the closure packet overclaims deterministic readiness:

1. canonicalizer rev3 has no executable N7 encoder and emits only the rehearsal marker;
2. N7 A4 says N7 binds N8, while the authoritative DAG says N8 depends on N7, creating a forbidden cycle;
3. N8 lacks a complete byte-exact seal roster/order/encoder;
4. P7 lacks an exact authority-seal artifact schema/encoding, so a prose-only official pin is prohibited.

Owner authorization is sufficient for the limited seal act but cannot cure these contract defects. Canonicalizer rev3 and Packet V3 tree remain verified candidates, not official authority pins. Implementation and every production/runtime gate remain blocked.
