Signal handling and graceful shutdown conventions for long-running processes (SIGTERM/SIGINT, drain in-flight work, idempotent units of work). Applies to servers, workers, and daemons in any language or runtime. TRIGGER when: writing or editing a process entrypoint / `main`, an HTTP or RPC server, a background worker, a queue consumer, or any daemon loop; wiring shutdown, signal handlers, or drain logic; user asks about SIGTERM, SIGINT, graceful shutdown, drain, or interruption safety in this repo. SKIP when: the code is a short-lived one-shot (a CLI that runs and exits, a library, a script) with no long-running loop, and the user isn't asking about shutdown.
