The gateway was the composition root, device registry, inbound-call policy, and call-operations service in one class, with core↔services circular imports papered over by function-local imports, wiring done by assigning private attributes, and MCP tools duplicating REST query logic against their own sessions. Composition: - main.py's lifespan now builds every service and wires them by constructor/registration. gateway.from_config() is gone; core/ no longer imports services/ anywhere — the cycle is dead. - Inbound-call policy moved to ReceptionistService.on_inbound_call (routing evaluation, reject/answer, screening dispatch); wired as the engine's on_incoming_call by the lifespan. Receptionist deps (tts/transcription/recording/routing) are constructor-injected — no more gateway._tts reach-through or importing hold_slayer's private _get_llm (now services.llm_client.get_llm, shared). - Hold-slayer launch goes through a mode-handler registry (register_mode_handler); the gateway no longer knows the service's type. CallManager takes on_call_ended in its constructor. - build_sip_engine() is a pure function taking explicit callbacks. - api/routing.py uses the routing service from app.state via a proper dependency instead of gateway._routing. Shared data layer: - db.session_scope() is the one session convention (get_db wraps it). - services/call_persistence.py gains the query/write functions and the single StoredCallFlow→CallFlow mapper; api/call_flows.py, api/call_history.py, and the six DB-touching MCP tools are thin wrappers over them — the two surfaces can't drift. - legs_for_call() replaces the three private _call_legs scans (gateway transfer/hangup, REST dtmf, MCP dtmf). 7 new tests (mode-handler launch, on_call_ended hook, receptionist inbound answer/reject, call-flow CRUD round-trip and history routes against real SQLite through the shared layer). aiosqlite added to dev deps for that.
