-## 5. MVP бизнес-приложения
+## 5. Application HTTP
+`PLBA` поддерживает отдельный прикладной HTTP-слой для пользовательских страниц и API бизнес-приложения. Он не смешивается с `control plane` и поднимается отдельным сервисом внутри того же runtime.
+
+`Control Plane` и `Application HTTP` обслуживают разные контуры:
+- `Control Plane` используется для `/health`, `/actions/*`, `/traces/*`.
+- `Application HTTP` используется для бизнес-маршрутов приложения, например `/estimate`, `/estimate/api/tasks`, `/api/orders`.
+
+### Основные компоненты
+- `ApplicationHttpService` управляет lifecycle прикладного HTTP на уровне runtime.
+- `HttpApplicationChannel` поднимает отдельный `FastAPI` app через `uvicorn`.
+- `HttpRouteRegistrar` регистрирует пользовательские routes и получает `ServiceContainer`.
+- `HttpApplicationAppFactory` собирает `FastAPI(title="PLBA Application API")`, middleware и routes.
+
+### Минимальный пример
+```python
+from fastapi import FastAPI, File, UploadFile
+from fastapi.responses import HTMLResponse
+from plba import ApplicationModule, HttpApplicationChannel, create_runtime
+
+
+class DemoRoutes:
+    def register(self, app: FastAPI, services) -> None:
+        @app.get("/demo")
+        async def demo_page():
+            return HTMLResponse("<h1>Demo</h1>")
+
+        @app.post("/demo/api/tasks")
+        async def create_task(file: UploadFile = File(...)):
+            payload = await file.read()
+            return {"filename": file.filename, "size": len(payload)}
+
+
+class DemoModule(ApplicationModule):
+    @property
+    def name(self) -> str:
+        return "demo"
+
+    def register(self, registry) -> None:
+        registry.add_http_routes(DemoRoutes())
+
+
+runtime = create_runtime(DemoModule(), config_path="config.yml")
+runtime.application_http.register_channel(
+    HttpApplicationChannel(host="0.0.0.0", port=15000, timeout=5)
+)
+runtime.start()
+```
+
+После старта runtime приложение будет обслуживать:
+- `GET /demo`
+- `POST /demo/api/tasks`
+
+### Типовые сценарии
+- `Web UI для фоновых задач`: список задач, запуск, статус, cancel, download result.
+- `Внутренний REST API`: например `POST /jobs`, `GET /jobs/{id}`, `POST /jobs/{id}/cancel`.
+- `Файловый шлюз`: загрузка входного файла, асинхронная обработка через worker, скачивание результата.
+- `Webhook endpoint`: прием callback от внешней системы и передача события в worker pipeline.
+
+### Ограничения и рекомендации
+- Не смешивайте business routes с `control plane`.
+- Держите бизнес-логику в сервисах, а handlers используйте как тонкий HTTP-адаптер.
+- Runtime предоставляет доступ к зависимостям через `services`, поэтому handlers не должны зависеть от `RuntimeManager`.
+- В первой версии `Application HTTP` не решает auth, static files, шаблонизаторы, websocket и OpenAPI customization.
+- Для публичного доступа выносите auth, TLS и reverse proxy на внешний ingress.
