      "summary": "Reviewed `src/math/libm_math/jnf.rs`, which is a direct Rust port of the `jnf` and `ynf` Bessel function implementations from libm/FreeBSD. I checked for install-time hooks, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `src/math/libm_math/k_cos.rs`, which is a straight port of the FreeBSD/libm kernel cosine approximation for `f64`. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
