📖What it means

An automatic check that notices work in a suspicious state and raises an alert. Watchdogs are ALERT-ONLY by rule: one that moved work itself would make the status router meaningless, and no watchdog may touch parked work.

📖Easily confused with

[{"term": "Watcher", "distinction": "A watchdog is a specific automatic check; a watcher is the agent role that owns detection."}, {"term": "Gate", "distinction": "A watchdog alerts after the fact; a gate refuses the transition as it is attempted."}, {"term": "Status router", "distinction": "A watchdog may never move status; the router is the only thing that can."}]

📖Also called

- stuck detector
- alarm
