useChannel

Raw-events escape hatch. Subscribes to one or more channels at a namespace and returns a bounded buffer of raw protocol events.

The buffer keeps accumulating across serial runs for the lifetime of the thread, so this is the hook to use for an event log / stream of a custom channel (e.g. ["custom:redaction-stats"]). When you only need the latest payload of a single custom:<name> channel, prefer useExtension. For the common message/tool/value cases prefer useMessages / useToolCalls / useValues.
