Anatomy of a dark factory

A 'dark factory' runs lights-out — no humans on the floor. Mine is a Claude harness brain on a VPS with a task queue (backlog → current → done), a security gate that scans for secrets and runs a language-agnostic SAST, a QA gate that runs tests and checks an ontology for consistency, plus a kill switch and a circuit breaker. You drop a task; the brain works in small verifiable steps; the gates block anything unsafe or broken; only then does it ship. This post went through all of it before you could read it.
