"""End-to-end relay round-trip against the in-memory stub connector.
Proves the gateway side of the relay works with no real connector:
- connect() registers the inbound handler,
- a connector-delivered MessageEvent reaches the adapter's message path,
- SessionSource discriminators (scope_id) drive build_session_key isolation,
- an outbound send round-trips through the transport.
These target the transport contract + session-key derivation (Task 1.2's gate),
not the full agent turn — handle_message is patched to capture the event.
