3 listediTime on the board is observed from the annual filings: the IRS files no appointment date, so the bar counts years from the first filing the person appears on - a lower bound, not a filed start date.

The network map shows same-name matches as likely links only, never as confirmed.Tenure and departures are observed across annual filings.
