The gateway dials OUT to the connector's relay endpoint over a WebSocket and speaks the newline-delimited JSON frame protocol defined in the connector repo (``gateway-gateway`` ``src/relay/protocol.ts``) and mirrored in ``docs/relay-connector-contract.md``: gateway -> connector : hello, outbound, interrupt connector -> gateway : descriptor, inbound, outbound_result, interrupt_inbound Frames: hello {type, platform, botId} descriptor {type, descriptor} (handshake reply) inbound {type, event, bufferId?} (a normalized MessageEvent) outbound {type, requestId, action} (send/edit/typing/follow_up) outbound_result {type, requestId, result} interrupt {type, session_key, reason?} (gateway egresses /stop) interrupt_inbound{type, session_key, chat_id} (connector -> owning gateway) This is the concrete transport behind the ``RelayTransport`` Protocol; the ``RelayAdapter`` delegates all wire I/O to it. Outbound calls block on a per-request future keyed by ``requestId`` until the matching ``outbound_result`` arrives. A background reader task pumps inbound frames to the registered handler and resolves pending outbound futures. EXPERIMENTAL: the frame schema may change without a deprecation cycle until at least two Class-1 platforms validate it. ) annotationsN) dataclass)AnyDictListOptional) MessageEvent MessageType) SessionSource)CapabilityDescriptor)InboundHandler>@i1c|xsdj}|jdrd|tddz}n"|jdrd|tddz}|jd}|j ds|d}|S) uNormalize a connector URL to the ``ws(s)://…/relay`` dial target. The relay URL is configured once (``GATEWAY_RELAY_URL`` / ``gateway.relay_url``) as the connector's BASE URL (e.g. ``https://connector.example``) and shared by both the provision POST (which needs ``http(s)://…/relay/provision`` — see ``_provision_url``) and the WS dial (which needs ``ws(s)://…/relay``, the path the connector mounts its ``WebSocketServer`` on). Two normalizations, both load-bearing: - scheme: ``https -> wss``, ``http -> ws`` (``websockets.connect`` raises "scheme isn't ws or wss" on an http(s) URL). - path: ensure it ends in ``/relay`` (the connector returns HTTP 400 on an upgrade to any other path, since the WS server is mounted at ``/relay``). Idempotent: an already-``ws(s)://…/relay`` URL is returned unchanged, so a URL configured WITH the scheme and/or ``/relay`` still works. zhttps://zwss://Nzhttp://zws:///z/relay)strip startswithlenrstripendswith)urlraws M/root/.hermes/venv/lib/python3.12/site-packages/gateway/relay/ws_transport.py _ws_dial_urlrAs$ 9"   C ~~j!S_-..

The connector attaches ``context`` as a list of normalized message objects (oldest→newest, same channel) for an addressed turn on a context-capable platform (design relay-channel-context). We flatten each to a ``: `` line so it rides the SAME read-only injection path that history-backfill already uses (run.py prepends ``channel_context`` ahead of the trigger message). This is REFERENCE context only — it never triggers the agent; the trigger decision was already made connector-side on the addressed event alone. Returns None when there is no usable context (absent/empty list, or a connector that doesn't send the field), so ``channel_context`` stays unset and behaviour is byte-identical to today. Never raises — a malformed context payload must not break inbound delivery of the (already-admitted) turn.

Sends ``going_idle`` and awaits the connector's ``going_idle_ack`` — the connector-AUTHORITATIVE confirmation that live delivery has stopped and subsequent inbound buffers durably (Q-5.3c). Returns True on ack, False on timeout / not-connected (the caller proceeds to close anyway — at worst a live event races a closing socket exactly as before §5.3, no regression). The gateway stays serving (the read loop keeps handling inbound) until the ack, so an event landing in the flip window is delivered live, not lost.

Distinct from BOTH ``disconnect()`` and an unexpected close (F14): - ``disconnect()`` sets ``_closing=True`` and CANCELS the reconnect supervisor — terminal, "shutting down for good." A machine suspended after that never re-dials on wake, so its buffered backlog strands. - An unexpected close re-dials IMMEDIATELY (fast backoff) — the socket never stays down, so the platform proxy never sees the connection go away and never suspends the machine. ``go_dormant()`` is the third mode the suspend behaviour needs: 1. ``go_idle()`` → the connector flips this instance to buffered-only and acks (so inbound that arrives while we sleep buffers durably and replays on the next handshake). 2. Close the socket so the platform proxy sees load drop to zero (the precondition for Fly ``autostop:"suspend"``) — but WITHOUT setting ``_closing``. The reader's normal end-of-socket fall-through still arms the reconnect supervisor, so the wake path stays live; the ``_dormant`` flag just makes that supervisor poll on the dormant cadence rather than fight the suspend window. On resume (process unfrozen) the supervisor's pending wait completes, the re-dial succeeds, and the connector drains the buffered backlog on the new handshake. Returns the ``go_idle`` ack result (True on ack); the dormancy close happens regardless (a missed ack at worst races one live event onto a closing socket, exactly as §5.3 already tolerates). No-op-safe: a transport that never connected (``_ws is None``) just returns False without closing.
