The record by year
On the record as of October 27, 2026.
An act sits on the day it happened: the day its own sentence names, or the day its source gives for it. An act the record knows only from the date of the article that reported it sits under that article's month, one tap away, marked Reported with the article's date. So do background, plans and statements, which are not acts. The same act reported by several sources is one line with the reports behind it, on its day where any of them dates it. The milestones alone, for every state, are on the timeline.
19 acts on the line for Wyoming, from 56 dated lines in the records' histories and the scorecard. 12 more acts are dated only by the article that reported them and sit under their month. 3 lines report an act already listed. 22 lines are background, plans or statements. 8 lines sit on a date other than the one they were filed under, because their own sentence names the day, the month or the year it happened; each says so. Where a line sits is read from its own words and the row is never changed (how dates are read).
2026 18 acts on the line from 21 reports; 12 reported, dated only by the article; 22 lines of background, plans and statements
September 2026 8 acts on the line; 6 reported; 16 lines of background, plans and statements
