Review Summary

Reviewed `src/math/libm_math/k_tanf.rs`, which is a small trigonometric helper implementing a polynomial approximation for `tan` with no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior. The file appears to be a direct port of FreeBSD/libm math code and only performs local floating-point arithmetic. Reviewed `src/hexagon/dfminmax.s`, which contains two Hexagon assembly routines implementing floating-point min/max helpers (`__hexagon_mindf3` and `__hexagon_maxdf3`) with simple conditional moves and returns. I checked for install-time execution, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators. Reviewed `src/hexagon/modsi3.s`, which is a small Hexagon assembly implementation of signed 32-bit modulo with a symbol alias to `__qdsp_modsi3`. 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. Reviewed `src/math/libm_math/arch/mod.rs`, which is a small architecture-dispatch module that conditionally re-exports math routines for wasm32, x86 SSE2, aarch64/arm64ec NEON, and a fallback x86 path. I checked it for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators, and found no concrete malicious or supply-chain compromise signals. Reviewed src/math/libm_math/hypotf.rs, which is a pure floating-point hypot implementation using bit manipulation and sqrtf for numerical edge cases. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.
