“You’re booked for Tuesday at 3” only counts if there is a booking for Tuesday at 3.
This reads what an AI phone agent told each customer, then checks every claim it made against the agent’s own tool logs. Below is a fictional home-services company, 154 labelled synthetic calls.
Each one opens to the claim, the evidence it was checked against, and the transcript. Agree or override — that click is the loop closing.
