FCA Hubs

Evidence-derived hubs are ranked from coverage artifacts, not static graph scores.

Substrate hubs

Substrate hubs are foundational concepts whose intent includes at least 90% of all collected tests. The percentage is breadth, not a quality score. They are auto-suppressed from PR impact summaries because they describe shared plumbing rather than a specific behavior.
