• Final status: FIX7_CODEX_RECHECK_9_HANDOFF_READY

Done this session (all command-backed)

1. P-EXT-1 applied exactly to SSOT .md (owner-authorized) → KB rev2; old 8f80f9f02cec…a1f12 → new 144eb3d9f44b…412a (post-apply content_length=31301 verified == local md2).
2. Packet refreshed post-patch: evidence .md→patched; materialized .py==extended (196d9801…, one canonical identity); RERUN.sh updated (step 2 22/22→36/36; +step 6 fail-closed verify); logs/expected-outputs regenerated by command; HASH_MANIFEST rebuilt (shasum -c all OK).
3. Anti-hardcode hardening (owner-driven): manifest.json is now command-generated (manifest_tool.py --emit) + fail-closed verified (--verify, exit 1 on tamper proven); codex_sealed_values_present: false; only literal is labelled historical ssot_old_sha256.
4. KB packet synced: manifest.json (rev3 generated+verified), manifest_tool.py uploaded, README_FOR_CODEX (post-patch banner + corrected stale values + demoted to NON_AUTHORITY + verify command).
5. Deliverables: report (TKT-OBJ-064), final handoff (065), blocker ledger (066), this checkpoint (067), governance update (068); registry md+json rev3→rev4; index rev89→90.

Evidence (command + exit + hash)

• bash packet/RERUN.sh → exit 0; RERUN_RESULT: PASS.
• python3 manifest_tool.py --verify → exit 0; MANIFEST_VERIFY: OK (33 literals); tamper → exit 1 (fail-closed proven).
• shasum -a 256 -c HASH_MANIFEST.txt → 25/25 OK.
• selftest 36/36 exit 0; produce membership_frozen_ok True, cand 144eb3d9…, exit 0; cross-tool membership f2bda8…fe251.

NOT done (forbidden / out of scope)

NO Codex consult · NO FIX7 approval/seal · NO production/PG/Directus/registry/system_issues mutation · NO REAL_RUN/QT001 apply/permit · NO activation/repoint/cutover · NO registries-pivot · NO auto-birth/scanner/trigger/taxonomy repair. N7/N8 NOT fabricated.

Cross-impact (Track 16)

Governance not weakened; birth-first not bypassed (new objects KB-governed, no production registry insertion); no parallel authority created (one canonical SSOT identity); auto-birth untouched; production not unblocked; registries-pivot not resumed; FIX7 approval NOT misstated (still owner/Codex-gated).

NEXT

Route the refreshed packet to Codex Recheck-9 to seal N7/N8/P7 + authoritative canonicalizer_sha256/revision. Owner separately decides the standing do-not-approve. See blocker ledger TKT-OBJ-066.
