Our latest article:
Modern evidentiary breath alcohol testing is driven as much by software as it is by hardware, and the printed test ticket is only a summary of what the instrument chose to report. This article explains what source code is, what it controls inside breath testing systems, and why transparency into software decision rules is essential to understanding the reliability and meaning of a reported breath result.

​A follow-up Counterpoint article will propose a practical transparency standard, including what information must be logged, preserved, and disclosed to support independent evaluation.
