Review Summary

Reviewed `src/math/libm_math/arch/i586.rs`, which contains small x86-32 `ceil` and `floor` helpers using `fabs`, integer truncation, and direct numeric comparisons. I checked for install-time hooks, network or exfiltration behavior, secret access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/math/libm_math/atanh.rs`, which is a small deterministic `f64` inverse-hyperbolic-tangent implementation using bit inspection and `log1p` for numeric edge handling. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence/tampering behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/math/libm_math/atanhf.rs`, which is a small pure-Rust `atanhf` implementation using bit manipulation, range checks, `log1pf`, and a signed return path. I found no concrete supply-chain or malicious indicators in this file: no install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution. Reviewed `src/math/libm_math/ilogbf.rs`, which is a compact `f32` `ilogbf` implementation that handles zero, subnormal, NaN, and infinity cases with bit inspection and `force_eval!` to preserve floating-point semantics. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators. Reviewed `src/math/libm_math/roundeven.rs`, which is a small set of IEEE 754 round-to-even wrappers for `f16`/`f32`/`f64`/`f128` that delegate to an internal generic rounding helper. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.
