Leak precedence
128days before filing

Days between the first leak-site claim and the first regulatory filing. Positive = the claim came first (public exposure before disclosure). Negative = the claim trailed the filing, so there was no pre-disclosure leak. Counts regulatory filings only — press coverage is not a regulatory disclosure.

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. This page states only what the linked filings agree on; each filing's own account stays on its own record, linked from the timeline below.
