Disclosure timing method
Observed filing gaps are not notice-date findings
The reporting deadline is the earlier of 30 days after notice or 45 days after the transaction. Public disclosure rows provide transaction and filing dates, but do not establish when a member received notice. PoliWealth therefore marks only transaction-to-filing gaps over 45 days as an apparent delay for review; 31–45 day gaps are not labeled late from transaction date alone.
