Enforce one shared shutdown deadline while persisting late digests during blocked sends. Start stall cooldowns from serialized delivery acknowledgements, atomically rewrite cleaned legacy outboxes, retain run summaries for 24 hours, and prevent duplicate history or synthetic post-process start times.
Bind the diagnostics flow to bearer-only authentication and reject query token attempts with controlled responses. Compare bearer token bytes with timing-safe equality, remove wildcard CORS, and mark diagnostics/support responses as no-store.
Move trace configuration mutation behind POST, add method failure handling, add a small per-IP/loopback in-memory request limit, and keep generated setup and support-manifest URLs token-free while pointing support access at a local bridge/tunnel flow.
Sanitize backup remote diagnostics on export and restore so legacy token, endpoint, host mode, and port values are not persisted; restores only keep the allowlist and force local binding.
Tests cover bearer accept/reject, query rejection, GET mutation rejection, no-store/CORS behavior, loopback default binding, rate limiting, token-free hints, and backup sanitation.
