      "summary": "Reviewed `src/math/libm_math/atan2f.rs`, which is a straightforward `atan2f` floating-point math implementation derived from FreeBSD/libm and contains only branch-based numeric edge-case handling. I checked for install-time hooks, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.",
