A div with header-only CSS never renders its bar: match element to selector. Subagent-killing gateway 529s on big-read briefs: resume once, then take the enumerated fix-list work over inline — docs/copy is orchestrator-legal and immune to the churn."

The ICP persona workflow (icp-user-test) caught a keyboard blocker 82 jest tests called correct."
