{
  "summary": "Reviewed the x86-64 assembly implementation of `p521_jmixadd_alt`, which is a hand-written P-521 mixed Jacobian point-add routine with local stack temporaries, register save/restore, and a normal `ret` epilogue. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
