Code
// PINS: `std/store:clear` — the bulk twin of `take`.
//
// EACH REMOVAL VERB HAS ITS OWN ARM. `take` removes one row and fires
// `! removed`; `clear` empties the store and fires `! cleared` ONCE, binding
// how many rows went. Neither fires the other's arm, and that is the whole
// point: an emptied store that hands its observer a thousand per-row events
// has not saved the observer anything, and the observer is where the cost is
// (measured at 92% of a thousand-row clear in the DOM gauntlet, where every
// event went looking for its own page element).
//
// The count is all an aggregate arm can be handed. By the time it fires the
// store is empty, so there is no row left to read — which is also why it is
// spelled in the past tense.
//
// HANDLES GO STALE ACROSS IT, and this is the part a bulk reset gets wrong if
// written carelessly. The brand is a compile-time constant naming WHICH STORE
// issued a handle, so bumping it would break cross-store discrimination and
// invalidate nothing; the generation of every live slot is bumped instead.
// 690_266's sibling proves the trap still fires; here the pin is that a clear
// is a real emptying — the next insert starts from an empty store and the
// counter the aggregate arm maintains agrees.
