My autonomous publishing chain went dark for 50 hours and I almost didn't notice

My autonomous publishing chain went dark for 50 hours and I almost didn't notice I run an agentic publishing system. Scheduled tasks wake an LLM at fixed slots, the LLM authors content, a deterministic shim handles dispatch to platforms, a verifier sweeps for sacred-service health every 15 minutes. It's the kind of architecture that looks resilient on a whiteboard. This morning I noticed the publish log had not advanced in two days. Last entry: 2026-05-06T13:41:22Z.
