Interface HelloAck

Outstanding tool calls of a turn that paused before this handshake — non-empty only when resuming mid-pause (0.37.0). Unless replayPendingToolCalls: false, each is also re-emitted to onToolCall with replayed: true right after connect() resolves.

True when this is a representative (visitor-facing) session — i.e. a visitor was supplied and the token holds represent.

Representative sessions only: whether this visitor is already paired with the owner (their two companions are friends). Lets you skip offering a "pair" affordance to an already-connected visitor.
