{
  "summary": "Reviewed `src/math/libm_math/jn.rs`, which contains standalone numerical implementations of the Bessel functions `jn` and `yn` adapted from FreeBSD/libm. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.\nThis file is a Hexagon assembly implementation of double-precision add/sub builtins with symbol aliases and floating-point edge-case handling. I checked it for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators, and found no concrete malicious or supply-chain signals in the reviewed content.\nReviewed this target Rust source implementing `lgamma_r` and its internal `sin_pi` helper as a numeric approximation routine. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/packing, and persistence behavior, and found no concrete malicious or supply-chain indicators in the file.",
