+The app runs with `youdis.py`.
+This starts the backend first, waits for health, then starts each enabled adapter explicitly.
+
+Test components directly with uvicorn:
+```
+python3 -m uvicorn youdis.main:app --host 127.0.0.1 --port 8000
+python3 -m youdis.adapters.discord
+```
+

+```
+YOUDIS_ENABLE_BACKEND=1  #default enabled, dont disable unless testing
+YOUDIS_BACKEND_HOST=127.0.0.1

+```
+
+to add a new adapter:
+1. add `youdis/adapters/<adapter>.py`
+2. make it independently runnable
+3. add `start_<adapter>()` to `youdis.py`
+4. register it in the explicit adapter starter map in `youdis.py`

+Build a simple Python orchestration layer in youdis.py so the standard app stack can be launched from one entrypoint while backend and adapters remain independently runnable for testing.
+
+** pm notes
+- keep components independently runnable
+- youdis.py as app-level orchestrator; let Docker just run python3 /app/youdis.py
+- no plugin discovery or hot-loading
+- Docker should package and launch the app, not decide internal process topology
+- preserve the ability to run backend or adapters directly for debugging
+- optimize for one obvious default run path
+
+** Acceptance Criteria
+1. define the default app startup path
+   - youdis.py launches the standard stack for v2
+   - backend and Discord adapter startup order is explicit
+   - shutdown behavior is coherent enough for local/dev use
+2. preserve modular run paths
+   - backend can still be run directly
+   - Discord adapter can still be run directly
+   - orchestration layer does not bury component-level testing
+3. keep orchestration simple
+   - no dynamic adapter discovery
+   - no hot reloading framework
+   - configured components are started explicitly
+4. document runtime ownership
+   - clarify what Python orchestrates vs what Docker orchestrates
+   - identify env vars or flags that control which components start
+   - leave room for future Zulip/XMPP adapters without redesigning the runner

+- `youdis.py` is now the default v2 app runner and starts the standard stack explicitly rather than dynamically discovering adapters
+- backend starts first and must pass a health check before the Discord adapter is launched
+- backend and Discord adapter remain directly runnable for debugging and tests
+- Docker is intended to invoke `python3 /app/youdis.py`; Python owns app orchestration while Docker owns packaging and runtime environment
+- adapter startup remains explicit in `youdis.py`, while each adapter gets its own `ENABLE_<ADAPTER>` flag
+- adding an adapter means creating `youdis/adapters/<adapter>.py`, adding `start_<adapter>()` in `youdis.py`, wiring its `ENABLE_<ADAPTER>` flag, and documenting any supporting env vars in `.env.example`
+- runner flags currently include `YOUDIS_RUN_BACKEND`, `YOUDIS_BACKEND_HOST`, `YOUDIS_BACKEND_PORT`, and `ENABLE_DISCORD`
