07 — Final Approval Verdict

FIX7_DESIGN_OFFICIALLY_APPROVED_FOR_IMPLEMENTATION_PLANNING

After the final design-approval review of T1's DESIGN_READY_FOR_CODEX_FINAL_APPROVAL, all six checks pass. The CP-06 hash micro-patch resolved T1's P-01..P-04 to a high standard; the single FIX7 acceptance gate — "H04/H05/H02 byte-implementable; every sub-payload key resolves to a named table.column" — is MET; and no contradiction was found in T1's final review. Codex formally approves the FIX7 design.

Check roll-up

Check Result
A — T1 final PASS integrity T1_FINAL_PASS_CONFIRMED
B — CP-06 micro-patch acceptance CP06_PATCH_ACCEPTED
C — non-regression NON_REGRESSION_ACCEPTED
D — zero / disguised hardcode ZERO_HARDCODE_FINAL_ACCEPTED
E — PG-first / native / driven PG_NATIVE_DRIVEN_FINAL_ACCEPTED
F — feasibility / scale FEASIBILITY_SCALE_FINAL_ACCEPTED

Approval rule satisfied: all of A–F pass → approve.

Invariants confirmed at approval

Exactly 27 authority surfaces · 11 non-authority runtime-evidence tables · 0 new readiness gates · 0 new top-level hash contracts (H01..H07 intact) · all live hard-blocks intact.

Scope of this approval — read carefully

  • Approved: the FIX7 design is promoted to the official approved design baseline.
  • Authorizes next: a separate implementation-planning / authoring phase (FIX7_IMPLEMENTATION_PLANNING_AUTHORING) may be initiated when explicitly requested.
  • Does NOT authorize: production implementation, Stage 2.6B, permit, REAL_RUN, QT001 apply, owner/ACL cutover, manifest activation, or any production mutation. Each remains BLOCKED until explicitly authorized at its own gate later.

Residual (non-blocking)

OBS-01 — a rationale-prose nuance in CP-06 patch doc 01 ("equal artifact bytes with equal SHA-256 remain content-equivalent across registry UUIDs") describes a case that the UNIQUE evidence_registry.artifact_sha256 makes unreachable. Editorial only; the deref rule and its determinism are unaffected. Carried forward for optional cleanup when the package is written into the official design; does not gate this approval.

Read-only attestation

This review applied no live SQL, created/mutated no production object, edited no T1 or prior Codex design doc, activated no manifest, opened no permit, and changed no ownership/ACL. Production remained READ-ONLY throughout. Outputs are KB design-approval artifacts only.

Result: FIX7_DESIGN_OFFICIALLY_APPROVED_FOR_IMPLEMENTATION_PLANNING.
