Final status

FIX7_REFACTOR_BLUEPRINT_T1_PATCHED_AFTER_CODEX_RECHECK_3_READY_FOR_CODEX_RECHECK_4

Summary

Codex recheck 3 accepted the Option-Beta disposition/STUB/DO_NOT_TOUCH-subtraction removal and the 27/11/14/7 + boundary invariants, and raised two narrow blocker classes. T1 patched both directly in the blueprint — no design amendment, Option Beta not reopened:

  1. Set separation: the mixed U_legacy = rule1 ∪ rule2 ∪ rule3 denominator is replaced by three distinct typed universes — U_legacy_object (PG objects; uniform-end-state both-EXCEPT, §H.4.A), U_effective_privilege_principal (roles; object × principal privilege join to #21, §H.4.B), U_entry_vector (trigger/event-trigger/scheduler/DOT/external; fail-closed bypass coverage, §H.4.C). U_legacy ≡ U_legacy_object; no set is a member of another.
  2. Superseded-history boundary: a machine-readable ACTIVE_AUTHORITY vs SUPERSEDED_NON_AUTHORITY boundary (doc 00 registry + per-doc DOC_STATUS markers + SUPERSEDED_NON_AUTHORITY BEGIN/END fences; not Directus-editable); G-LEGACY-NO-DISPOSITION-AUTHORITY re-scoped to ACTIVE_AUTHORITY.

Guards 42 → 47 (+G-U-LEGACY-OBJECT-ONLY, +G-PRINCIPAL-SET-SEPARATE, +G-ENTRY-VECTOR-SEPARATE, +G-ACTIVE-AUTHORITY-SCOPE, +G-NO-SUPERSEDED-CONSUMPTION) + guard-quality rules 7+8. Invariants 27/11/14/7 preserved (0 new authority surface, readiness gate, top-level hash contract, #20 column, or catalog family — the new sets are evaluation constructs and the boundary is document metadata). All hard blocks intact. No fresh live read required (prior pg_roles evidence stands).

Codex-style self-check (required by the macro)

# check verdict basis
1 U_legacy object-only (PG objects only) PASS doc 02 §H.2/§H.4.A; G-U-LEGACY-OBJECT-ONLY
2 principal separation (principals only in U_effective_privilege_principal) PASS §H.4.B; G-PRINCIPAL-SET-SEPARATE
3 entry-vector separation (DOT/scheduler/external only in U_entry_vector) PASS §H.4.C; G-ENTRY-VECTOR-SEPARATE
4 uniform end-state owner/body/#21 proof applies only to U_legacy_object PASS §H.3/§H.4.A; G-U-LEGACY-OPTION-BETA-UNIFORM-ENDSTATE
5 privilege check uses U_legacy_object × U_effective_privilege_principal PASS §H.4.B; G-PRINCIPAL-SET-SEPARATE / G-NOLEGACY-POST
6 bypass checked separately and fail-closed PASS §H.4.C; G-ENTRY-VECTOR-SEPARATE (uncovered vector fails closed)
7 active-authority boundary machine-readable PASS doc 00 registry + DOC_STATUS markers + fences; G-ACTIVE-AUTHORITY-SCOPE
8 no-disposition guard fails on old terms in ACTIVE_AUTHORITY; not on fenced history PASS doc 06 G-LEGACY-NO-DISPOSITION-AUTHORITY re-scoped; rule 8
9 no superseded consumption by implementation packages PASS G-NO-SUPERSEDED-CONSUMPTION; doc 07 sequencing
10 hardcode / PG-native: no pattern/name/owner/manual-history scan is authority PASS doc 08 self-review (11/11)
11 cross-layer: implementation / 2.6B / permit / REAL_RUN / QT001 apply / activation / repoint / cutover blocked PASS doc 09; doc 08 §A

Internal self-check: 11/11 PASS.

Why READY_FOR_CODEX_RECHECK_4 (not the other allowed statuses)

  • Not ..._NEEDS_MORE_T1_WORK: both narrow blockers are fully patched in-blueprint against existing surfaces; the three typed sets and their guards are defined, and the boundary is machine-readable; no residual T1 gap.
  • Not ..._FAIL_HARDCODE_OR_PG_NATIVE_GAP: the patch adds no name/pattern/owner/manual-history authority; membership = PG-object closure, privilege = catalog/pg_auth_members tuple to #21, bypass = catalog entry-vector coverage, boundary = document metadata (not Directus-editable).
  • Not READ_PATH_BLOCKED: the recheck-3 package, the Option-Beta patch, the current blueprint, the amendment/approval sources, and the prior live evidence 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 4 only.
