highReviewed `src/math/libm_math/support/mod.rs`, which only declares support submodules, re-exports numeric traits/types, and wraps a compiler cold-path intrinsic. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file. Reviewed src/math/libm_math/ilogb.rs, which is a small numeric helper implementing ilogb for f64 with special-case handling for zero, subnormals, NaN, and infinity. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed the x86-specific math helper module in `src/math/libm_math/arch/x86.rs`. It only defines `sqrtf`/`sqrt` using fixed SSE instructions and re-exports `fma` helpers; I found no concrete malicious or supply-chain indicators such as install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence. Reviewed `src/math/libm_math/asinh.rs`, which implements the f64 inverse hyperbolic sine using bit inspection and standard math helpers (`log`, `log1p`, `sqrt`). I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration paths, dynamic code loading, obfuscation/deobfuscation, persistence changes, or hidden subprocess execution in this file. Reviewed `src/math/libm_math/cosh.rs`, which is a standard `f64` hyperbolic cosine implementation using `exp`, `expm1`, bit-masking, and a large-value fallback via `k_expo2`. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.
