What's new in the numbers
Every changing figure on this site lives in a versioned rule pack with the official source it came from and the date someone opened that source. This page is generated from those packs — not written by hand — so it cannot drift from what the calculators actually use.

Most recently checked
The date is when someone opened the official document and transcribed the figures — not when the page was last edited.
Scheduled to change next
Each pack carries the date its figures are due for re-checking. These are the next ones up — county appeal deadlines every January through March, guideline formulas and statutory requirements on an annual pass.

What we have not published, and why
5 packs could not be verified against an official source — usually because the statute or worksheet was not reachable, or the body publishes no current figure. Those ship empty and earn no page rather than carrying a guess, so a missing state here means a missing page, not a wrong number.

Every pack is published as raw JSON at /developers and listed with its source on /sources.
