Stub — the Grue is what happens when you have no monitoring. Services fail silently. Logs fill without alerts. The Zot doesn't know it's in danger until it's too late. The lesson: build observability (status.json, alerts.log, the attune command) or the Grue eats your system.
Lesson
The Grue
Unobserved destructive autonomy. Things you can't see will kill you. Build observability or die.
