/**
 * time/bind — which of the person's windows a tool call carries (time
 * design § 5.6, § 7.3): fill from one mention, bind by quote, and record a
 * differing model window and run it.
 *
 * Pattern: Walker over recorded rows. The turn's WINDOWS are read from what
 *          the record already holds — this turn's `time-answer` rows (a
 *          mention the person settled in the time ask), a `model` reader's
 *          `time-reading` rows (a reading, never the person's) and the
 *          `clock` row's `control` window — never from words. A `rule`
 *          reading settles nothing: it is a proposal the person confirms
 *          (the owner's decision "Always confirm", time design TQ29). One call's decision
 *          ({@link callWindowOf}) is a pure function of its arguments, the
 *          tool's forms and those windows.
 * Role:    L0 leaf (the time layer). Imports `convert.ts`, `range.ts`,
 *          `rows.ts`, `resolve.ts`' types and `zone.ts` only. Asked by the
 *          inputs layer (`arguments/resolve.ts`), which files the argument
 *          rows and the `call-window` row the decision implies.
 * Emits:   N/A.
 *
 * ## The laws
 *
 * - **Fill only when the turn has exactly one window.** A message holding two
 *   mentions ("this morning vs yesterday morning") fills nothing: which one a
 *   call means is the model's to say, through the quote. A mention whose
 *   reading is still open (the person has not chosen) is counted and fills
 *   nothing; a refused mention (its quote was not in the message) is not the
 *   person's words and is not counted. A `control` window (`time.window`, set
 *   in a UI) counts as one more mention with no quote.
 * - **Fill only what the model left out — exactly, else wider, never
 *   narrower.** Every argument of every form must be missing; the window goes
 *   into the first form that holds it exactly (`convert.ts` · `convertExact`),
 *   else the first that holds MORE (`convertWidened`: a whole day, the
 *   covering look-back — recorded with what it adds). No such form → the call
 *   is REFUSED, `no-form-holds` (`convert.ts` · `convertForTool`, the one
 *   answer): the tool's own rule never stands in for the person's window, so
 *   an assumed `1h` never silently reads a time the person did not ask about.
 * - **Refuse before dispatch what the tool cannot honestly read (step
 *   T5b).** A window — the person's to fill, or the model's sent — outside
 *   the tool's declared `direction`, wholly beyond its `retention` or wider
 *   than its `maxRange`; a range across days for a tool whose every form is a
 *   `day`; a window of the person's no form can read (`no-form-holds`); a
 *   sent wall time the zone skips. A window only partly beyond `retention`
 *   runs, marked. An open reading the tool can read in NO reading is refused
 *   too, and never asked.
 * - **A present window is never written over.** Bound by quote (the model's
 *   declared `user` quote names a recorded mention) or by value (the sent
 *   value, read back, IS a window of this turn); otherwise it runs as sent and
 *   is recorded `model-chosen` beside the person's window — a drill-down, a
 *   comparison and a baseline call are normal work.
