Interface ActiveBridgeSession

The voicing agent's MJ: AI Agents id — stamped on this agent's transcript lines for attribution.

The names/aliases this agent answers to (moderator roster + addressed-only fallback).

A short role/description of the voiced agent (moderator relevance context).

The voiced agent's MJ: AI Agent Runs id — tied to each moderator prompt run for observability.

The MJ: AI Agent Sessions row id the bridge is attached to.

This session's own bot participant id on the endpoint — the speaker label on its own transcript lines.

The concrete driver instance transporting media.

The server-side channel host wired for this session (Part A), or undefined when the caller supplied none. Held so teardown can close the session's channels.

Epoch-ms when this session connected — drives the max-session-duration cap of the stale sweep.

The context user the session runs as (for participant upserts / teardown writes).

Whether the model's blind auto-response is OFF for this session (multi-agent meeting). When true the bridge is the sole speech trigger — a Speak decision issues one RequestSpokenUpdate. When false the model auto-responds and the engine stays hands-off (forcing would double-fire).

Executes ONE server-channel tool call for this session, routed through the channel host. Bound by the runner-constructing layer to RealtimeSessionRunner.ExecuteServerChannelTool. undefined when no channel host was supplied. Never throws — resolves to a structured failure.

Safety timer that force-releases a held floor after FLOOR_MAX_HOLD_MS in case the agent's final transcript never arrives — so one agent can't wedge the room's floor closed. Cleared on a normal release.

Whether at least one HUMAN participant has been seen in the room. Auto-leave only fires after a human was present and then all humans left — so a bot that joins ahead of anyone (or a momentarily bot-only roster at startup) is never reaped prematurely. Set by the occupancy check off the driver roster.

Whether this session currently holds the room's speaking floor (multi-agent floor control). Set when the engine claims the floor before triggering speech in meeting mode, cleared when the agent's own final transcript lands (it finished) or on teardown. Single-agent rooms always hold trivially.

Whether THIS session is the room's transcript scribe. Exactly one session per room writes the unified meeting transcript (its own speech + everything it hears), so a multi-agent room records one copy, not N. Elected at connect (first session in the room); re-elected if the scribe leaves.

Epoch-ms of the last inbound activity (transcript) — drives the idle cap of the stale sweep.

The participant identity of the most-recent inbound AUDIO frame (when the provider diarizes). Used to attribute a 'user' transcript to the speaker who produced it — since the model transcript itself has no speaker label. Approximate (single-speaker-at-a-time); undefined until the first diarized frame.

Pending grace timer started when the last human leaves. If a human rejoins within the grace window (e.g. a page refresh) it is cleared; otherwise it fires AIBridgeEngine.StopBridgeSession so the bot leaves the empty room and its co-agent run finalizes. Cleared on any teardown.

The metadata provider bound to this session's entity operations.

This agent's participation style for the room moderator ('proactive' | 'addressed-only').

The provider row backing this session.

The realtime session the driver's media plane is wired to.

The room key (driver ExternalConnectionId) this session is in — the unified-transcript room grouping.

The server-executed tool definitions the session's channels contributed at connect (e.g. the Meeting Controls facilitator tools). Empty when no channel host / no contributing channels. The runner-constructing layer registers these as RealtimeSessionRunner.ServerChannelTools.

The AIAgentSessionBridge row id (the durable record).

The TARGET agent this co-agent voices (role/identity source for the moderator), when distinct from ActiveBridgeSession.AgentID.

The per-session turn-taking policy gating generation.
