software testing

AI writes code fast — but a 2025 Veracode study found models chose insecure code 45% of the time, and a METR trial found developers 19% slower. Here is the gap.

CRUCIBLE is a governance protocol that audits whether an AI agent's own test-and-coverage system provides evidence not controlled by the same producer. Three forensic cases: 3,277 passing tests hid silent data loss; a 77% coverage badge masked an audit estimate of ~15%; 4,726 passing tests could not prove real-database reachability.
