13 - Final Verdict (T1 FIX7 Blueprint Patch After Codex Recheck - Owner Semantics)

Verdict

FIX7_REFACTOR_BLUEPRINT_T1_PATCHED_AFTER_CODEX_RECHECK_READY_FOR_CODEX_RECHECK_2

T1 patched all recheck blockers (A-H) directly in the blueprint, grounded on fresh read-only live evidence and the approved byte-level DDL, then self-reviewed against Codex's exact failed checks. No production mutation; no implementation; no hardcode; no PG-native gap; no DDL drift; no design amendment required; read path open.

Self-review against Codex's 10 recheck checks

#	check	verdict
1	PostgreSQL owner semantics: directus effective EXECUTE only expected 0 after it is no longer owner	PASS (S15.1 transfer precedes S15.2 revoke precedes S15.3 verify; directus non-superuser)
2	No phase deadlock: PRE before action, POST after action	PASS (PRE structural/no-revoke; POST after transfer+revoke)
3	No mixed authority: ACTIVE authority cannot coexist with executable legacy	PASS (STAGED at S14; activate at S15.4 after neutralization; G-NOMIXED keys on ACTIVE route fact)
4	No DDL drift: no column added to approved byte DDL without amendment	PASS (0 new #20 column; approved columns + computed disposition; manifest-seal integrity)
5	Closed legacy denominator: sealed/manifest/hash-bound, not name-pattern	PASS (U_legacy closed universe; G-LEGACY-TARGET-CLOSED-DENOMINATOR)
6	Rollback source: any body change has a real source artifact, or is not allowed	PASS (sealed evidence_registry body; no-artifact ⇒ REVOKE_ONLY)
7	Operator authorization clearly separated from qt001_backfill_permit	PASS (evidence_registry non-authority evidence; G-NO-QT001-PERMIT-DURING-FIX7)
8	Hardcode: no pattern/name/owner scan acts as authority	PASS (diagnostic-only scans; final authority PG-native)
9	PG-native/driven: final authority is PG-native/manifest-bound	PASS (catalog/ACL/closure/manifest-seal; owner-transfer obeys PG semantics)
10	Cross-layer: 2.6B / QT001 apply / permit / REAL_RUN / governance / registry-pivot remain blocked	PASS (all blocked/later; unchanged)

Why this status (and not the others)

• Not FIX7_REFACTOR_BLUEPRINT_PATCH_AFTER_RECHECK_NEEDS_MORE_T1_WORK: every recheck blocker was directly fixable and fixed in-blueprint; the self-review passes all 10 checks; the decisive PG owner-semantics root cause is resolved by reordering the phases (owner transfer first), not by hand-waving.
• Not FIX7_REFACTOR_BLUEPRINT_PATCH_AFTER_RECHECK_REQUIRES_DESIGN_AMENDMENT: every fix binds to an already-approved surface/column (approved #20 columns, #27, manifest seal, evidence_registry, #11, #22, PG roles). No new column, surface, hash contract, readiness gate, or catalog family is added. The lone design-owner item is a CONFIRMATION of the LEGACY_*-in-#20 semantic scope, which needs no byte-DDL change (BLOCKER-C option 1).
• Not FIX7_REFACTOR_BLUEPRINT_PATCH_AFTER_RECHECK_FAIL_HARDCODE_OR_PG_NATIVE_GAP: checks 8/9 PASS - the closed denominator removes implementer-selectable "live-relevant"; disposition is computed (no vocabulary); the set-hash is replaced by the governed manifest seal; final authority is PG-native throughout and obeys PostgreSQL owner/superuser semantics.
• Not READ_PATH_BLOCKED: all Codex recheck docs, the prior patch docs, the current blueprint, the approved byte-level DDL (#20/#26/#27/evidence_registry/catalog), the design index, and live production (pg_roles superuser status, ownership) were all readable read-only.

PostgreSQL owner-semantics verdict

OBEYED. directus is non-superuser; ownership transfer off directus (S15.1) precedes the REVOKE (S15.2), so directus effective EXECUTE = 0 is reachable at S15.3. The superuser workflow_admin is explicitly dispositioned (inherently ACL-bypassing, outside FIX7's removable scope). No guard expects an owner's effective privilege to be zero without an ownership transfer.

Boundaries (unchanged)

Official FIX7 design remains approved. The blueprint and implementation-authoring planning are NOT approved. 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; no object was created, altered, owned, granted, revoked, or executed. The only writes were the blueprint-doc revisions, this report, and the two checkpoints.

Do not claim implementation approval. Next after this PASS is Codex recheck 2 only.
