-**`orchestrator.py`** (~4060 lines): FastAPI entry point. Initializes all services as module-level globals, populates `ServiceContainer`, includes all routers. Legacy OpenAI-compatible `/v1/*` endpoints still live here. `StreamingTTSManager` extracted to `modules/speech/streaming.py` (Phase 4.1).

Legacy OpenAI-compatible `/v1/*` endpoints still live here. Extracted: `StreamingTTSManager` → `modules/speech/streaming.py` (Phase 4.1), widget public endpoints → `modules/channels/widget/router_public.py` (Phase 4.2).
 
 **`ServiceContainer` (`app/dependencies.py`)**: Singleton holding references to all initialized services. Routers get services via FastAPI `Depends`. Populated during app startup.

+### Phase 4.2: Widget public endpoints → modules/channels/widget/router_public.py
+
+> **Статус:** реализовано (PR [#566](https://github.com/ShaerWare/AI_Secretary_System/pull/566), issue [#547](https://github.com/ShaerWare/AI_Secretary_System/issues/547))
+
+6 публичных (без auth) widget endpoints + 4 helper-функции извлечены из `orchestrator.py` в `modules/channels/widget/router_public.py`.
+
+**Endpoints:**
+- `GET /widget.js` — динамическая генерация JS-скрипта
+- `GET /widget/status` — проверка enabled
+- `POST /widget/chat/session` — создание сессии
+- `GET /widget/chat/session/{id}` — получение с историей
+- `POST /widget/chat/session/{id}/stream` — SSE стриминг ответа
+- `POST /widget/chat/session/{id}/contacts` — контакты → amoCRM
+
+**Ключевые решения:**
+- Импорты модернизированы: `async_*_manager` → domain singletons (`widget_instance_service`, `chat_service`, `config_service`, `cloud_provider_service`, `user_identity_service`)
+- amoCRM helpers оставлены lazy (try/except) для graceful degradation
+- Widget path: `Path(__file__).parents[3]` (учитывает глубину модуля)
+- 4 неиспользуемых импорта удалены из orchestrator
+
+**Результат:** orchestrator.py: 4062 → 3544 строк (−518)
