Final status

DESIGN_READY_FOR_CODEX_FINAL_APPROVAL

Codex's CP-06 hash micro-patch (codex-fix7-cp06-hash-micro-patch-from-t1-proposals-2026-06-07/00..06) resolves T1's prior P-01..P-04. All four verified against the ground-truth runtime-evidence DDL (codex-fix7-design-correction-…/02 rev 2). The single FIX7 acceptance gate — "H04/H05/H02 byte-implementable; every sub-payload key resolves to a named table.column" — is now MET. Zero blocking proposals remain. Genuine advance — not a hardcode / PG-native / scale / read-path failure.

Per-track verdicts

• P-01 H04 evidence deref: P01_VERIFIED — reviewer_evidence_hash/binding_evidence_hash deref signoff_binding.{reviewer,binding}_evidence_id → evidence_registry.evidence_id → evidence_registry.artifact_sha256; both are real NOT NULL FKs; no *_evidence_hash column exists (the prior contradiction was real; the deref is the fix). UUID never hashed; missing evidence fails (NOT NULL FK + ON DELETE RESTRICT).
• P-02 H04_SCOPE_V1: P02_VERIFIED — exactly 8 ordered keys (activation_id, target_manifest_id, plan_content_hash, quorum_profile_id, required_principal_class_id, slot_ordinal, action_id, control_epoch), ALL real NOT NULL signoff_binding columns; closed set; consumed consistently by signoff_binding UNIQUE + H04 + RP-06; stronger than T1's 4-key minimum; domain incomex.qt001.signoff-scope.v1; not a new top-level contract.
• P-03 H05/H02 total orders: P03_VERIFIED — 5 aggregates (H05 measurements/artifacts; H02 capability-hashes/post-activation-state; + signoffs); each order PK-terminated against DDL (contains/ends the table PK); membership pinned & bounded (run_id / control_epoch); tier_id NULLS FIRST, finalized_at non-NULL via "finalized runs" membership; UTC / COLLATE "C" / missing-extra-fail / empty-only-if-source-empty.
• P-04 extra-index: P04_VERIFIED — every extra index/constraint fails OBJECT_AUTHORITY_IMMUTABLE; no benign exemption; legitimize only via a new sealed #20 manifest version + quorum (exceeds the advisory ask).
• Non-regression: NON_REGRESSION_VERIFIED — 27 authority surfaces; 11 runtime-evidence tables (count-verified from DDL); 0 new gates; 0 new hash contracts (H01..H07 intact, H01 recomputes transitively, H03/H06/H07 unchanged); hard blocks intact; no RP-01..08 / CP-01..09 regression; 2 in-patch corrections (target_id→target_manifest_id alias fix; defined verifier membership) are improvements within existing tables.
• Zero-hardcode: ZERO_HARDCODE_VERIFIED (incl. disguised). PG-native-driven: PG_NATIVE_DRIVEN_VERIFIED (Codex PG_NATIVE_PASS_DESIGN_OPERATOR_GATED_LIVE consistent). Feasibility/scale: FEASIBILITY_SCALE_VERIFIED (object-count-independent; bounded membership; no new apply path).
• Proposals: 0 blocking. One optional editorial observation OBS-01 (P-01 rationale prose vs UNIQUE artifact_sha256) — non-blocking.

Law alignment (prompt-muc-tieu-mo v1.3)

§3.4 (no Authority Pack ⇒ read-only/author-mode only), §4H (design-only forbids mutation), §4I (implementation only after design acceptance), §4F/§4G (surgical follow-up; stop on semantic/governance drift), §5/§6 (no fake PASS, no production mutation without gate) all confirm the READ-ONLY posture and the do-not-advance stance. §4K Queue Law N/A (no queue/messaging/trigger design). Hash-contract / total-order / authority-surface-count / disguised-hardcode concepts are T1/Codex review discipline (not law clauses), applied as discipline.

Hard blocks unchanged

Implementation, Stage 2.6B, permit, REAL_RUN, QT001 apply — all BLOCKED. Production READ-ONLY throughout.

Next

Codex final-approves the FIX7 design → promotes to official design. THEN (later authorized phases only, each still BLOCKED now and each requiring its own gate): implementation macro → Stage 2.6B (permit/run/keyset/resume + authority revoke) → permit → REAL_RUN → QT001 apply.
