How it works

Evidence

Maricopa County · evidence records supporting the roll

Evidence exists, verifies, and is accepted

Every value the report relies on resolves to a dated artifact whose hash still matches and which the engineer has accepted.

Every judgment has an author and a reason

Engineer-owned changes and basis values are attributable, so a reviewer can ask a person why a number is what it is.

Where this stands

An artifact is captured from the same county navigation that reads the value, hashed on arrival, and verified against that hash on every later read. Acceptance is a separate, accountable act by the engineer. A captured document is not evidence until it verifies and is accepted.
