Approved brainstorming design: a Workflow tab that splits a loaded
workflow's unresolved nodes into Missing (defer to Manager) and Disabled
(enable temporarily under a 7 distinct-boot-day rolling trial, or
permanently). Backend tracks trial state and counts boot-days; frontend
drives Manager enable/disable (Approach A).
