-- Authored post-escape cinematic states; exact native completion/skip incidents advance once.
--
-- An authored region is `sliceSetIndex + stateOrdinal`, so apex gameplay (region 0) and both
-- ending bookends (regions 1 and 2) are sibling states of one slice set. Selecting a bookend
-- instantiates no new world, so no slice-set teleport is armed for it -- and that also means the
-- client never sends another region report. Waiting for one leaves the movie unstarted forever,
-- which is exactly what a run with the teleport removed showed: the state was selected and no
-- cinematic was ever enqueued.
--
-- So the activation is queued with the selection instead of on a later callback. Intents are
-- dispatched in order and a state selection completes only once its own roster revision has
-- published, so the cinematic Auth always follows the seed that carries its slot. Slot handles
-- resolve against the static SDK definition table, not the selected state, so naming the
-- bookend before its state is live is safe.
