"""Test-only in-memory stub connector implementing RelayTransport.
MUST stay under tests/ — never under plugins/ or gateway/ (a CI guard in
test_no_stub_leak.py asserts this). It lets Phase 1 prove the gateway side of
the relay end-to-end with zero dependency on the real (Node) connector.
The stub:
- hands back a fixed CapabilityDescriptor at handshake,
- lets a test push synthetic inbound MessageEvents (push_inbound),
- records every outbound action (sent/interrupts) for assertions,
- answers get_chat_info from a small fixture map.
