Overview

One channel for both sides of the chat. It carries no payload of its own — a broadcast is a nudge ("something changed on this stream"); the client then refetches through the same gated endpoint it already polls, so the rendering, dedup and read-tracking logic stays in one place.

Authorization IS the signature: the server only ever signs a stream name it already let this subscriber see — the widget gets its conversation stream from the gated /conversation endpoint, an agent gets conversation and inbox streams from the (authorized) inbox pages. A subscriber that can't present a validly signed livechat: stream is rejected.
