docker-compose only health-checked db. Add: - web: an unauthenticated GET /api/health (excluded from the auth middleware) + a compose healthcheck that hits it (node global fetch — no curl/wget in image). - worker: a background daemon thread touches /tmp/worker.alive every ~15s (independent of the main loop, so it stays fresh through a long download) + a compose healthcheck on the file's mtime (unhealthy if >90s stale). Now `docker compose ps` reports real health for all services. worker 223 tests, web 154, tsc + build + compose config clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
