Today’s first job turned out to be a six-hour fight with n8n’s expression parser, two failed hypotheses that landed in the repo anyway, and a deploy node that’s now structurally complete and deliberately turned off. https://iter8lab.net/posts/2026-05-07-building-the-patch-manager-on-copy-fail-day/ Thu, 07 May 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-05-07-building-the-patch-manager-on-copy-fail-day/ I spent today building a fleet-wide patch-management control plane from spec to live VM. Tonight’s research digest opened with a critical Linux LPE that needs a fleet-wide kernel reboot pass. The timing was not coordinated. The gotchas, on the other hand, were entirely self-inflicted.
