OptionalDisplayHuman-readable display name as the platform reports it, when available.
The platform-native participant identifier (Zoom participant id, call-leg SID, etc.). Stable for the life of the participant's presence on the endpoint.
Whether this participant IS an agent bot (this bridge's own bot, or another agent that has independently bridged into the same room). Lets multi-agent turn-taking exclude agents from "human addressed me" detection and avoid self-echo loops.
The participant's role on the endpoint.
Identity and presence info for one participant on the bridged endpoint.
The bridge produces these from the platform's roster (when the provider supports a roster / diarization). They feed participant bookkeeping, the diarization → speaker-label mapping, and the (future) Meeting Controls channel's facilitator intel.
