- Gateway, Trips, Fitness Dockerfiles: run as non-root (appuser)
- Added HEALTHCHECK to gateway, trips, fitness
- Used --chown=appuser on COPY for correct file permissions
- Created data dirs with proper ownership before USER switch
- Trips Dockerfile no longer copies whole context (only server.py)
Partial fix for #10 — Node services (inventory, budget, frontend) not yet hardened.
- Disable open /api/auth/register endpoint (gateway)
- Require gateway session auth on Immich and Karakeep hooks proxies
- Replace SHA-256 with bcrypt in fitness service (auth + seed)
- Remove hardcoded Telegram user IDs from fitness seed
- Add Secure flag to session cookie
- Add domain allowlist and content-type validation to image proxy
- Strengthen .gitignore (env variants, runtime data, test artifacts)
