| 1 | """A live room (docs/games.md §8): one game of kaggle-environments' Werewolf with people, agents and bots at the seven |
| 2 | seats, speaking the room protocol through kit/room.py. Seat "0"-"6" is Player 1-7 and the engine deals the roles |
| 3 | (seeded by SS_ROOM's seed, else at random). A bot runs a route's or a field folder's main.py in a process of its own per |
| 4 | seat, as in the checks, 3 s a move; a seat on auto, a person out of time and a bot that fails or answers out of turn |
| 5 | are played by the offline evidence-based computer, with a private journal per seat. Public things are events; what one seat alone may know (its role, the |
| 6 | wolves' picks, the seer's results, the doctor's heals) is told to that seat. At the end the game is left in replays/ in |
| 7 | the practice replays' format with a matches.json entry, so it lists as a match. |

| 16 | seconds} before a person's or an agent's speech or day vote |
| 17 | to a seat {kind: heal|saved|inspect|wolf_vote|wolf_pick, ...}: the doctor's, the seer's and the wolves' own night |
| 18 | request {to, version, obs: {seat, player, role, team, wolves, day, phase, request, alive, known, events, seconds, |
| 19 | raw}, legal}: request is chat, vote, kill, heal or inspect; known is what was told to the seat, events the public |
| 20 | ones so far (the last 40), raw Kaggle's own raw_observation, so a Kaggle agent can play from it |
| 21 | chat: legal [{type: chat, message: ""}], answered with the message filled in (trimmed, at most 600 characters; |
| 22 | left empty, the seat passes) |
| 23 | kill|heal|inspect|vote: legal [{type, target: seat}], day and night votes also {type: vote|kill, target: null} to abstain |
| 24 | an answer may add "reasoning" (kept for the replay), or be the Kaggle agent's own action, as main.py returns it |
| 25 | event {kind: over, winner, reason, roles, out}, then end {result, scores}: 1 for each seat of the winning team |
