Leak precedence

124days 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.
