Since issue 372 the router answers the same answer again from the same account with 'You already chose Approve at HH:MM: recorded.', on the tap's acknowledgement rather than in the chat. The proof from #74 still waited for a chat refusal, so it failed on every mesh-lab pull request. The lab's phone now keeps a tap's acknowledgement words, and the replay subtest waits for them; its checks that nothing more is done stay.
