{
  "summary": "Reviewed `src/hexagon/dffma.s`, a Hexagon assembly implementation of double-precision fused multiply-add and its special-case handling for NaN, infinity, and zero. I checked for install hooks, hidden subprocesses, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/float/div.rs`, which implements IEEE floating-point division via reciprocal approximation/Newton-Raphson and special-case handling for NaN, zero, infinity, and subnormals. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential/secret access, dynamic code loading, obfuscation/packing, persistence tampering, or unrelated system probing.",
