/**
 * A gap counts as repaired only when there is REAL evidence: the repair pipeline
 * marked it `repaired` AND it carries a concrete signal, one or more promoted
 * facts, or one or more accepted new sources. A node merely going `stale`
 * (superseded) or being marked `not_applicable` (deemed non-repairable) is NOT
 * repair evidence; those gaps stay open honestly instead of being auto-resolved
 * with an invented reason. (Invariant 4 / honesty.)
