The API image ran four uvicorn workers, and each one built a full flow controller — four sets of MQTT subscriptions, cron ticks and webhooks. Runs one worker now; scaling out is the worker split, not more processes. Adds a loop-lag watchdog and a deep /utils/health/ that fails when the event loop is wedged or Redis is unreachable, the two failure modes a process-alive check never sees. Autoheal restarts on that signal, behind a compose profile because it mounts the Docker socket. The private user-seeding routes now need an explicit opt-in rather than just ENVIRONMENT=local, so a deployment that kept the default never exposes them.
