/**
 * .what = runs one attempt's body against a time budget, and reports how it ended
 * .why = a repeatable attempt must be able to withhold any failure — a throw or an
 *        overrun alike. the runner's own timer fails a test from outside any catch, so
 *        the wrapper owns the deadline and turns an overrun into a returned error
 *
 * .note = an overrun does not cancel the body; it cannot be cancelled. the body may
 *         still settle later, and its result or rejection is dropped on purpose
