 * Hold the task's first prompt back: `ref.reason` is `text` in the engine's reminder frame, `ref.detail` names `cause`.

 * bounded, envelope tags defused, with no reminder frame and no session mark; a reason that folds to nothing leaves the
 * key out. For every other cause `text` is the engine's sentence about the hook's ending and `hookReason` is never minted.
