The forensic replay bundle is the piece worth hardening most carefully before production use. A BLOCK verdict is only as useful as your ability to prove, after the fact, that it happened exactly as recorded - especially when the agent is acting on behalf of a user in a regulated context (EU AI Act Article 12, DORA). Right now the logs live inside the same runtime that enforces policy, so a compromised host could alter the replay bundle before it hits storage. Anchoring the hash of each verdict in an append-only transparency log (Sigstore Rekor works for this) would shift the claim from "we have a log" to "we have proof this log existed at time T and is unchanged" - a meaningfully different evidentiary position when a blocked connector onboarding ends up in a dispute.
