An audit is a photograph, a test suite is a habit

A smart contract audit acts as a photograph, covering only one specific commit at a single moment. While valuable, it cannot account for subsequent changes, such as updated dependencies, adjusted fee parameters, or last-minute deployment script edits. In contrast, a test suite is a habit. Unit, fork, and invariant tests integrated into CI ensure that every following commit remains reliable, providing continuous security that a static audit report from months prior cannot offer.
