 # internal-platform

+
+### Patch Changes
+
+- Named side channels on a Session: durable, two-way realtime streams that outlive a single run and are shared across runs. Open a channel with `sessions.open(id).channel(name)` (or `chat.channel(name)` inside a `chat.agent`) to get an `.in`/`.out` pair addressed by name rather than the reserved default pair. Writing a side channel's `.in` does not wake or trigger a run, so a channel can carry out-of-band data (a stream of frames, a control signal) that many clients read while the agent produces it. ([#4815](https://github.com/triggerdotdev/trigger.dev/pull/4815))
+
+  ```ts
+  // Inside a chat.agent: stream frames on a named channel, wakes nothing
+  const frames = chat.channel("screenshots");
+  await frames.out.append(frame);
+  frames.in.on((control) => {
+    /* client control, no suspend */
+  });
+  ```
+
+  Declare channel record types once with `sessions.defineChannel(...)` and infer them on both the producer and the consumer, including `useSessionStreamChannel` in React. Channels get a default retention that keeps them bounded, overridable per channel.
