HTTP Services & Proxies The Pattern Problem: You need a web service that does more than serve requests — it has a background loop reconciling state, it proxies WebSocket connections to a backend process, and it must start reliably even when the previous instance didn't exit cleanly. Approach: FastAPI lifespan for startup/shutdown, asyncio.createtask for background loops, bidirectional WebSocket relay for proxying, and pre-bind port cleanup to prevent systemd crash-loops. Pattern proven in production across multiple Python CLI tools and web services. Key Design Decisions 1. Pre-bind port cleanup — preventing the restart crash-loop When systemd restarts a service, the old process may still hold the port in TIMEWAIT. The new process fails to bind, exits with status=1, systemd restarts it, repeat. In one production deployment, 2,075+ systemd restarts occurred before manual intervention. The fix runs before uvicorn.run(): python def killstaleportholder(port: int) - None: """Kill any existin
