Inputs and bounds, outputs, invariants and tolerances, refusal names and meanings, the published reference, and a worked example for one solver. With form "short" the answer is a page, enough to write a first request: what the model is of, how it did against measurement, each input with its unit and range, the names of its stops, and a worked request. Read the full form, the answer when form is left out, when a request is refused or before relying on a result: only it has each bound's reason, the validation record and each stop's meaning.
