Reversal agent resolves disputed trip fees on MongoDB Atlas. It reads the complaint, walks the trip graph, recalls only the memories that actor is allowed to see, checks the ledger, and refuses to move money until policy allows it. A small route dispute is dismissed because a stored rule changes the outcome. A charge above 25 CAD waits for an elevated operator. A cancellation-fee reversal survives a crash without posting twice. A bad memory can be forgotten and stays out of the next recall. Every tool call is an audit row tied to an actor.
