Review rev_5ddd79c8ce0c45a79992995937c0cf98

{
  "summary": "Reviewed `src/math/libm_math/generic/fminimum.rs`, which implements IEEE 754 `minimum` selection and a final canonicalization multiply. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/int/bswap.rs`, which only defines three byte-swap intrinsics (`__bswapsi2`, `__bswapdi2`, `__bswapti2`) that delegate directly to Rust's `swap_bytes()` for 32-, 64-, and 128-bit integers. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior in this target file.\nReviewed `src/float/mod.rs`, which is a small module-export file that only declares float submodules and conditionally re-exports `Float` and `HalfRep` behind a feature flag. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `src/math/libm_math/generic/fmaximum_num.rs`, which implements IEEE 754 `maximumNumber` selection for floating-point values and a final canonicalization multiply. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering; none are present in this target file.\nReviewed `src/math/libm_math/generic/fminimum_num.rs`, a small IEEE-754 `minimum` helper that selects between two float operands and canonicalizes the result. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
