Gate cannot pass: the task's strict.rs walks 28 wire fixtures but 16
(approvals/approve/refuse/ok/grants_report/turn_event_* and friends) do not
exist on the m3a branch and are created by task 02. The audit types were
implemented exactly as specified and records passes; only the unrelated
wire-envelope test blocks the gate. Committed only this log row.
