I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `src/math/libm_math/coshf.rs`, a standalone `f32` hyperbolic cosine implementation that uses bit masking and magnitude thresholds to dispatch to `expm1f`, `expf`, or `k_expo2f` with a small forced-evaluation path for underflow-sensitive inputs. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.",
