  "$comment": "Reference strings must resolve to existing canonical Work/Role/Runtime records in a later binding. They are not new identities. Authenticated principal and authority are checked independently of self-reported protocol metadata. Idempotency record is durable and bound to payload hash; reconcile unknown effects instead of blind retry."
