The hand-raise queue in RAISE ORDER (oldest first) — who is waiting and for how long.
The participant ids the agent has muted via the channel (best-effort mirror of mute state).
The current roster (every known participant, agents included).
The participant ids currently speaking (diarized), in no particular order.
The active agenda/meeting timer, or null when none is set.
The full perception payload the channel serializes back to the model — the facilitator's situational awareness in one object: the roster, the ordered hand-raise queue, who is speaking, and the timer.
