      "summary": "Reviewed `src/math/libm_math/remquo.rs`, which implements the `remquo` floating-point remainder/quotient routine and a small test. I checked it for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior.",
