ProvenanceOverlapSignalScorer

class ProvenanceOverlapSignalScorer constructor(weight: Double = 0.5) : CollectorSignalScorer

Scores how much two propositions' rich provenance overlaps, as Jaccard similarity of their com.embabel.dice.provenance.SourceLocators. Locators compare by structural equality, so this catches "same source material" even when grounding chunk ids differ or are absent.

Abstains when either side has no provenance entries at all — there's no evidence to compare. Weighted conservatively (0.5), same reasoning as grounding overlap: corroborating, not conclusive on its own.

Parameters
