Fernbank Operations needs a short production-readiness review for its request flow. It handles new and repeated references, writes a tracking item, notifies the owner and leaves an audit trail. A green email card doesn't establish that the tracking key is unique, and a failed later action doesn't automatically undo an earlier write.
These tasks revisit keyed create-or-update logic, ownership settings and recovery scope. They also ask you to identify which evidence remains uncertain after a timeout. Use the current destination state in the hidden fixture instead of assuming every incoming event is new. A good handoff lets another maintainer identify a request, inspect the effects already completed and recover the missing work without creating another copy of the business event.
