Merge provenance

Method: deterministic
Confidence: 1.00 · above the 0.85 auto-merge floor
Reviewed: operator-confirmed · at least one link edge was human-adjudicated
Audit: Every link edge records its method, confidence and model + prompt versions (100% is the strongest edge).

Merges are reversible — a wrong link can be detached with its audit trail intact. How merging works.

About this clustering

DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
