      "summary": "Reviewed `src/math/libm_math/tanh.rs`, which is a standard floating-point `tanh` implementation using bit manipulation, `expm1`, and a subnormal/overflow handling path. I checked for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
