 ## Network
 
 All services share the default network. The network is marked `attachable: true` to allow external containers (like Authentik) to join.
 
-## Caddy profile
-
-Caddy (ports 80 and 443) is **optional** and behind the `caddy` profile so it does not conflict with an existing reverse proxy (e.g. Coolify, Traefik, nginx).
-
-- **With Caddy** (you want Reflector to handle SSL):
-  `docker compose -f docker-compose.prod.yml --profile caddy up -d`
-- **Without Caddy** (Coolify or another proxy already on 80/443):
-  `docker compose -f docker-compose.prod.yml up -d`
-  Then configure your proxy to send traffic to `web:3000` (frontend) and `server:1250` (API).

-Hatchet child workflow: TrackProcessing
-
-Handles individual audio track processing: padding and transcription.
-Spawned dynamically by the main diarization pipeline for each track.
-
-Architecture note: This is a separate workflow (not inline tasks in DailyMultitrackPipeline)
-because Hatchet workflow DAGs are defined statically, but the number of tracks varies
-at runtime. Child workflow spawning via `aio_run()` + `asyncio.gather()` is the
-standard pattern for dynamic fan-out. See `process_tracks` in daily_multitrack_pipeline.py.
-
-Note: This file uses deferred imports (inside tasks) intentionally.
-Hatchet workers run in forked processes; fresh imports per task ensure
-storage/DB connections are not shared across forks.
