/**
 * act — PUBLIC. One bundle for every place a rule may speak.
 *
 * Pattern: Facade over five doors, with the facade's KEYS type-locked to the
 *          list of moments they cover.
 * Role:    core/ layer. `.act()` builds nothing new: it validates a bundle
 *          and calls `.messageMiddleware()`, `.toolMiddleware()` and
 *          `.window()` with exactly what a person would have passed by hand.
 *          Everything about a run is decided by those doors, here and there
 *          alike.
 * Emits:   N/A.
 *
 * ## Why a bundle at all, when the doors already exist
 *
 * Because the doors are findable one at a time and the POSTURE is not. An
 * agent's governance currently reads as four unrelated calls scattered
 * through a builder chain, and the question a reviewer actually has —
 * "what does this agent do at each point in its loop?" — has no place to be
 * answered. `.act({ … })` is that place: five optional keys, named for the
 * five moments, so autocomplete on an empty object teaches the loop.
 *
 * ## The completeness lock
 *
 * The keys of {@link ActOptions} are pinned, at compile time, against
 * `ActKey<LoopMoment>` — the moment list, camel-cased. Add a sixth moment to
 * `LOOP_MOMENTS` and this file stops compiling until the bundle grows the key
 * for it; delete a key and the same. A surface that claims to be complete has
 * to be made unable to fall behind, or the claim is just a sentence in a doc.
 *
 * The runtime half is derived from the same list: the accepted key set is
 * `LOOP_MOMENTS.map(actKeyFor)`, so a typo'd key is refused by a validator
 * that cannot drift from the type it is validating.
