      "summary": "Reviewed `src/math/libm_math/cbrtf.rs`, which is a straightforward `f32` cube-root implementation using bit manipulation and two Newton iterations. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `src/math/libm_math/ceil.rs`, which contains small wrapper functions for `ceil` across `f16`, `f32`, `f64`, and `f128` that delegate to `super::generic::ceil` or architecture-specific selection macros. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",

      "summary": "Reviewed `src/math/libm_math/cosf.rs`, which is a straight f32 cosine implementation that does range-based dispatch to `k_cosf`, `k_sinf`, and `rem_pio2f` for argument reduction. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence/tampering logic.",
