Nightly golden-diff verification

A test bench for production scrapers.

Every published actor runs against its live source each night and is diffed against a frozen fixture. The board below is that verdict — verified as of 2026-09-07 09:00 UTC. The method is source-agnostic; the proof is the hardest targets we hold: CAPTCHA-walled state license portals.

Actor health

44 published actors, diffed against their live sources by the nightly golden-diff canary. Success = share of canary runs that matched the golden fixture; "insufficient data" means too few runs so far — never 0%. "Last checked" is the time since each actor's most recent canary run. The board is verified as of 2026-09-07 09:00 UTC.
