      "summary": "Reviewed `src/hexagon/umoddi3.s`, a Hexagon assembly implementation of 64-bit unsigned modulo with a public alias for `__qdsp_umoddi3`. It contains only arithmetic/branching control flow and no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain payload behavior.",

      "summary": "Reviewed the Hexagon assembly implementation of `__hexagon_umodsi3`, which performs unsigned modulo arithmetic and aliases `__qdsp_umodsi3` to the same routine. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
