Final status

FIX7_REFACTOR_BLUEPRINT_T1_PATCHED_AFTER_CODEX_RECHECK_4_READY_FOR_CODEX_RECHECK_5

Summary

Codex recheck 4 accepted the recheck-3 set separation + boundary and 27/11/14/7, leaving one blocker class: the ACTIVE_AUTHORITY corpus was classified only by mutable KB markers/registry/fences and not pinned to the exact reviewed revisions/content hashes (a mutable authoring-authority denominator / disguised hardcode), which also kept the no-disposition guard, the hardcode-final check, and authoring-planning blocked. T1 patched it in-blueprint — no runtime design amendment, nothing accepted reopened.

The fix: an immutable, content-addressed ACTIVE_AUTHORITY_APPROVAL_ENVELOPE (doc 00) pinning every ACTIVE doc/section + KB revision + normalized SHA-256, plus marker-fence / registry / guard-set / membership / manifest hashes, anchored to the Codex recheck checkpoint, sealed at the Codex recheck; four fail-closed guards (G-ACTIVE-AUTHORITY-APPROVAL-ENVELOPE / -HASH-MATCH / -REVISION-MATCH / -CHANGE-FAIL-CLOSED); the no-disposition / no-superseded / scope guards re-bound to the sealed envelope; guard-quality rule 9; PKG-A gated on a SEALED, verified envelope.

Guards 47 → 51. Invariants 27/11/14/7 preserved — the envelope is a non-runtime construction-document content-address (it pins the docs being authored from), explicitly NOT a runtime authority surface, readiness gate, #20 column, catalog family, or 8th top-level runtime hash contract (H01..H07 stay 7). All hard blocks intact. No fresh live read required.

Self-check (Codex-style)

# check verdict
1 approval envelope defined, machine-readable, all required fields PASS (doc 02)
2 revision + SHA-256 per ACTIVE doc/section; membership hash real now; body hashes seal at recheck-5 PASS (doc 02)
3 fail-closed on revision / content / marker-fence / registry / guard-set / section-identity / membership / doc-status PASS (doc 03; G-ACTIVE-AUTHORITY-CHANGE-FAIL-CLOSED)
4 G-ACTIVE-AUTHORITY-APPROVAL-ENVELOPE / -HASH-MATCH / -REVISION-MATCH / -CHANGE-FAIL-CLOSED added PASS (doc 03)
5 G-NO-SUPERSEDED-CONSUMPTION + G-LEGACY-NO-DISPOSITION-AUTHORITY depend on the sealed envelope PASS (docs 04, 05)
6 no silent post-approval drift; mismatch → Codex recheck, not "continue authoring" PASS (docs 03, 05; rule 9)
7 adversarial self-audit (11 scenarios, incl. the self-reference hole) all fail closed PASS (doc 06)
8 hardcode/PG-native: mutable denominator content-addressed; no runtime authority added PASS (doc 07)
9 cross-layer: implementation / 2.6B / permit / REAL_RUN / QT001 apply / activation / repoint / cutover blocked PASS (doc 08)
10 non-runtime: no new surface / gate / #20 col / catalog family / runtime hash contract PASS (docs 07, 08)
11 accepted items not reopened (Option Beta, set separation, STUB removal, DO_NOT_TOUCH, 27/11/14/7, PG-native, cross-layer) PASS

Internal self-check: 11/11 PASS.

Why READY_FOR_CODEX_RECHECK_5 (not the other allowed statuses)

  • Not ..._NEEDS_MORE_T1_WORK: the single blocker class is patched in-blueprint; the content-addressed envelope + four fail-closed guards + the re-bound guards + rule 9 are in place; the 11-scenario adversarial self-audit passes.
  • Not ..._FAIL_HARDCODE_OR_PG_NATIVE_GAP: the patch REMOVES a disguised hardcode (mutable authoring denominator) by content-addressing it; it adds no runtime authority/surface; Codex's PG_NATIVE_FINAL_ACCEPTED / INVARIANTS_BOUNDARY_FINAL_ACCEPTED are preserved.
  • Not READ_PATH_BLOCKED: the recheck-4 package, the recheck-3 patch, the current blueprint, and the approval sources were all readable read-only.

Boundaries

Do not claim implementation approval. Implementation, Stage 2.6B, qt001_backfill_permit, REAL_RUN, QT001 apply, manifest activation, repoint, and owner/ACL cutover all remain BLOCKED. Production was READ-ONLY throughout. Next is Codex recheck 5 only — which seals the ACTIVE_AUTHORITY_APPROVAL_ENVELOPE (computes + records the per-document hashes over the approved content, flips envelope_state to SEALED, records it in the recheck-5 checkpoint).
