Only official sources: state pay plans and salary schedules, union contracts, agency hiring pages, state retirement systems and training-standards rules. Never salary-estimate sites.
Every fact on a page links to the source it came from, with the date we checked it.
Two independent checks: each record is re-read against its sources by a second and third reviewer; a fact ships only when two of three agree.
If we can't find a fact officially, we leave it blank instead of guessing. A state gets a page only when it has at least two state-specific official facts.
Pay is the base scale for the entry title, before overtime, shift differentials and hazard pay.
