      "summary": "Reviewed `src/math/libm_math/expm1.rs`, which is a pure Rust port of the standard `expm1` floating-point routine with a small sanity test. I checked for install-time hooks, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
