      "summary": "Reviewed the x86-64 assembly in `p521_jadd_alt.S`, which implements P-521 Jacobian point addition and associated field-math helpers using fixed carry-propagating arithmetic, stack temporaries, and conditional moves. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess behavior.",
