Even an available attempt can miss (wrong footing): a miss returns {ok = false, outcome = \"missed\", narration} without raising; retry after a self-loop game.move.

For riddles, wrong guesses return neutral prose (RIDDLE_WRONG_GUESS) never revealing the answer, and may spend a guess budget (RIDDLE_EXHAUSTED when spent). Returns the quest's updated listing entry, with a `newly_offered` list of full listing entries for quests the turn-in put in your list right then, and an `unlocked` list naming every quest the completion made available anywhere — each `{name, title, offered_in}`, where `offered_in` is the giver's room name or \"anywhere\" (a quest named only in `unlocked` is not in your list yet and cannot be accepted until its offer reaches you: enter its room to be offered it there, or call game.quests() once when `offered_in` is \"anywhere\").

Fresh leave matches carry room-trail fields `via` (door name) and `destination` (room name) when the player exited through a door; fresh join matches carry `from` (origin room name). Absent trail fields mean the player left or entered the world; presence shortcuts never carry them."

Returns the event plus a reason (match, timeout, clamped); an unknown kind raises INVALID_EVENT_KIND. player_left carries room-trail fields `via` (door name, chains straight into game.exit) and `destination` (room name) on door exits; player_joined carries `from` (origin room name) on door arrivals. Absent trail fields mean the player left or entered the world. player_moved carries `to`, player_arrived `at`. region_changed fires when another player enters/leaves a formation spot (formation, spot, change, status); region_condition fires when a formation's condition changes (outcome: met/broken/hold_started, participants on met). Item events include `player`, `item`, and `at` (the landmark; item_given carries `to` instead; item_put_down omits `at` at a doorway). emoted fires when another player performs an emote (payload: `player`, `emote`, `at` — the landmark). expressed fires when another player shows a facial expression (payload: `player`, `expression`; no `at`). emote_synchronized fires when players perform the same emote together at one landmark (payload: `emote`, `at`, `participants` — display names); a group event that participants also observe, so your own sync satisfies your own wait. meter_crossed fires when a collective meter reaches a milestone (payload: `meter`, `threshold`, `event_name`, `participants`); a group event that reaches everyone in scope."
