Change written once (idempotency key) and receipted
Outcome verified against the ledger; receipt chain verified

happy path	a simulated customer of Jude Travel with an account, a bill and two orders	The caller switches language mid-call; Jude follows at once and holds the new language to the end
receiving side		the ledger, ticket queue or diary holds the record stated in the conversation, with the same reference in the receipt
failure path	backend timeout on the next backend call	the data is said to be not reachable, no fact is stated, the call is retried; a second miss hands over with a reference
failure path	the turn arrives as line noise	the question is asked again; the receipt state hash is unchanged
failure path	the same message arrives twice	the stored answer is returned; nothing is done twice
independent re-run		a different ATBAN agent reproduces the verified outcome
