Walks a whole purchase in the order a buyer asks the questions, stopping at the first that objects. Nothing is signed and nothing is spent. The payment check asks the narrower question, about a payment you have already decided on.
Over the endpoints WE have knocked on, which is our reach and not the catalogue. A disagreement is between two statements by the SAME party, their listing and their endpoint, so it is theirs to explain and never ours to resolve; it is not evidence of fraud and a seller may simply have moved their payee and not relisted. `comparable` is the denominator: an endpoint that names no payee, or whose listing names none, cannot disagree and is not counted either way.
Which endpoints, and whose, needs a plan. Any single endpoint you name is free: search for it above and its own reading is on the row.
The rehearsal could not be run. That is not the same as it saying no: nothing here objected, and nothing here was established either.
