Review rev_3e4414173b29445da253fd1691fb02cf

{
  "summary": "Reviewed `src/math/libm_math/expo2.rs`, which contains a small pure-math helper for `exp(x)/2` implemented with constant arithmetic and a call to `exp`/`combine_words`. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `src/math/libm_math/k_expo2.rs`, a small Rust math helper that computes a scaled exponential using fixed floating-point constants. I found no concrete malicious or supply-chain indicators in this file: no install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `src/math/libm_math/k_expo2f.rs`, which is a small floating-point math helper that computes a scaled `expf` approximation using fixed constants. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `src/hexagon/func_macro.s`, a small assembler macro file that only defines `FUNCTION_BEGIN` and `FUNCTION_END` wrappers for symbol declaration, text section setup, alignment, and size metadata. I checked for install-time execution, hidden subprocesses, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.\nReviewed `src/math/libm_math/generic/copysign.rs`, which is a small pure arithmetic helper that copies the sign bit from one floating-point value to another via bit masking and reconstruction. I checked for install hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found none in this file.",
