Class SessionWithRecv

Snapshot actions currently tracked as in-flight.

Attach and drive one transport endpoint.

The returned status covers the stream startup handshake. The session keeps pumping it afterwards; await done for connection-wide completion.

Await all actions observed during the wait and aggregate their failures.

Request cooperative cancellation of one active action.

Request cancellation of every action without waiting for teardown.

Resolve, acknowledge, and start one inbound registered action call.

Apply a received fragment, including reserved action-status nodes.

Dispatch every action and fragment in one validated inbound message.

Await full cleanup and receive the session's terminal status.

Begin clean shutdown and half-close every active stream with OK trailers. Existing inbound work may still arrive and attached streams must still finish before done resolves.

Whether either endpoint has ended the session for new work.

Whether every attached stream has completed and state is fully quiescent.

Queue a message on a named stream or round-robin across active streams.

Replace the registry and rebind active actions for later name resolution. Prefer configuring it before dispatch so one operation does not observe registrations from different registry versions.

Replace the node map and rebind active actions. Existing fragments remain in the old map, so prefer configuring this before traffic starts rather than splitting a live action's state.

Snapshot the streams currently attached to this session.

Track an action so concurrency, cancellation, and shutdown include it.
