      "summary": "Reviewed the x86-64 assembly implementation of `p521_jdouble_alt`, which performs P-521 Jacobian point doubling using local field-arithmetic macros, stack temporaries, and register save/restore only. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
