Status: AVAILABLE (contract; verifier-owned completion for agency-origin work). See status labels. A verifier checks a subject and emits a VerificationReceiptV1. It never marks work done.

Architecture contract

Choose the kind (parse, format, lint, typecheck, unit test, integration test, build, semantic rule, requirement, security, regression, diff review or human). Return PASS, FAIL, INCONCLUSIVE or ERROR, evidence references, whether you are deterministic and whether a retry can help. INCONCLUSIVE is never PASS. Deterministic verifiers outrank semantic ones.

Current implementation

Verifier-owned completion is on main for agency-origin work.
