0 of 12 positives; 12.6 false alarms per 100 ordinary pushes (2.1 on changed lines only). The misses come from what the rules and facts express (access control lives in obligations, which do not convert; sources cover request objects only), not from the engine. Comparison arm only: a Semgrep miss is never evidence against a hunter finding. Co-Authored-By: Claude Opus 5.5 <[email protected]>
