- Add GET /health route (DB + Redis ping, 200/503) with Dockerfile HEALTHCHECK directive - Replace config.py stub with real pydantic BaseSettings reading directly from env vars; remove external config file mount from docker-compose - Add requirements.lock (pip freeze snapshot for bit-identical builds) - Untrack config.py globally but allow app/config.py via .gitignore negation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
