      "summary": "Reviewed the ARM assembly implementation of `p521_jmixadd_alt`, which performs straight-line P-521 mixed Jacobian point addition with stack/register save and restore plus a zero-input fallback path. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, or persistence tampering in this file.",

      "summary": "Reviewed this header of preprocessor macros that only map symbol names and visibility directives for Apple vs non-Apple builds. I checked the file for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence hooks, and found no concrete malicious or supply-chain indicators.",
