Leak precedence
150days before filing

Days between the first sighting of the earliest-seen leak-site claim and the first regulatory filing. Measured from when the aggregator first saw the post, not the crew's own (often earlier) date. 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.
