Most counties are audited by a state agency or an independent firm, and those reports are public record. We haven't yet obtained and machine-read one for Arlington County — so this is a dead end in our sense of the word: not navigable here yet, never hidden. When a report is in hand it's quoted and cited on this page, with the regulatory-basis note up front so boilerplate isn't misread as scandal.
