- I-1: evaluate_shadow counts dropped rows by cause (unparseable /
unknown_tier / explicit / duplicate) with the identity
audit_rows_total == routed_task_n + dropped_total; the shadow
endpoint passes created_at/id through and reports audit totals
next to sample counts.
- I-2 (option b): parse logs a warning naming each tier dropped for
an invalid mode/requires; load attaches partial_failures to the
policy; the worker records a task-level
worker_routing_policy_load_failed audit for partial failures
(same action as full failure, detail says failure=partial);
the shadow report carries the policy fingerprint, dropped tiers
and partial failures (no task context on that path, so no
task-level audit there).
- I-5: coordinator gate audit lookup failure now raises
_CoordGateLookupFailed and the merge converts it to escalate
(no requeue, no round consumed); persisted-model lookup failure
and required-tools check failure each write a named audit row
before falling through to dispatch/allow; audit-loop evaluate
failure stays escalate (regression test).
- Test fixtures: coordinator suites build audit_log via AuthStore
as production's first real audit does, since their stubbed
_audit never creates the table.
