Everything this person has disclosed to the SEC on Form 4 — across every company they file for — reconstructed from the public record. A filing history, not a tip sheet.
Pattern in the record: open-market sales filed in May in multiple years since 2024 — a recurring calendar cadence, more consistent with scheduled activity than a one-off decision.
