Bill data from LegiScan, licensed CC BY 4.0. The record chooses the bills, writes each stage in its own words and cites the legislature's own page for every bill.
A row's day is the day the event happened, or, where a source gives only its own publication date, that date. The same rows appear on the record pages they belong to; this page is the dated log of them. A row read in a tier 1 query feed is a lead, not an entry, and appears on its record page only.
