📖What it means

A long-running program the operating system supervises: it is started at boot, restarted if it dies, and stopped on command. This is the machine's sense of the word — plumbing, not business. Carolverse's shared machinery (the relay, the grounding layer, the status router) is registered as system services so that the parts nobody 'owns' as a product still have an owner and a watcher.

📖Easily confused with

[{"term": "Service", "distinction": "A system service is machinery on the box; a service is a line of business with a budget. The words are identical and the meanings do not overlap at all."}, {"term": "Daemon", "distinction": "Every system service is a daemon, but a daemon nobody registered with the OS is not a system service \u2014 and nothing restarts it when it dies."}, {"term": "App", "distinction": "A system service has no face; an app is a page a person opens."}]
