03 — CHECK C: Non-Regression Final Acceptance

Verdict: NON_REGRESSION_ACCEPTED

What CHECK C requires

27 authority surfaces; 11 non-authority runtime-evidence tables; 0 new readiness gates; 0 new hash contracts; no RP-01..08 regression; no CP-01..09 regression; Stage 2.6B blocked; permit/apply/REAL_RUN/QT001 apply blocked.

Evidence (T1 doc 05 ⋈ CP-06 patch doc 05 ⋈ index rev 25)

Invariant Required Observed Result
Authority surfaces exactly 27 27, unchanged (DDL "net new = 0"; index rev 25; CP-06 patch self-review) ACCEPTED
Runtime-evidence tables 11, non-authority 11 physical tables (signoff_binding, capability_run [env folded in], capability_measurement, capability_artifact, gate_fact_result, bypass_vector_fact_result, quorum_vote, denied_attempt_evidence, dashboard_export, level_b_packet_execution, post_activation_verifier_state); owner qt001_cp_owner; Directus/PUBLIC-inaccessible; typed #20 enumeration ACCEPTED
New readiness gates 0 0 ACCEPTED
New hash contracts 0 0; H01..H07 intact; H01 recomputes transitively; H03/H06/H07 unchanged ACCEPTED
RP-01..RP-08 no regression intact; RP-06 STRENGTHENED by P-02 (slot now provably hash-bound) ACCEPTED
CP-01..CP-09 no regression intact (retention #05; expected-constraints typed #20; catalog families; item_payload descriptive-only; Directus sealed read-contract) ACCEPTED
Stage 2.6B blocked blocked ACCEPTED
permit blocked blocked ACCEPTED
REAL_RUN blocked blocked ACCEPTED
QT001 apply blocked blocked ACCEPTED

Two in-patch corrections = improvements, not regressions

  1. H02 signoff order alias target_id → real column signoff_binding.target_manifest_id (DDL-confirmed) — required for byte-implementability.
  2. Undefined "expected verifier set" → defined membership (valid post_activation_verifier_state rows for executed manifest_activation at H02.control_epoch, ≥1 per executed activation). Both stay inside existing runtime-evidence tables; introduce no new surface, gate, or contract.

Determination

The micro-patch was hash-spec-only. No authority surface, readiness gate, hash contract, runtime table, or Directus authority was added; the surface count and all hard blocks are unchanged; RP/CP positions are intact (RP-06 improved). No regression.

Result: NON_REGRESSION_ACCEPTED.
