{
  "summary": "Reviewed `src/math/libm_math/j1.rs`, which is a standard Rust port of the FreeBSD `j1`/`y1` Bessel-function implementation using polynomial approximations and helper math routines. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and hidden subprocess behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/libm_math/mod.rs`, which is a Rust module hub for libm-style math routines, macro helpers, conditional re-exports, and bit-manipulation utilities. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, or persistence in this file.\n`src/math/libm_math/exp2.rs` is a self-contained `f64` base-2 exponential implementation with a large constant lookup table, polynomial approximation, and explicit overflow/underflow handling. I checked for install-time hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden execution indicators, and found no concrete malicious or supply-chain signals in this file.",
