  "summary": "Reviewed the target x86-64 assembly implementation of P-256 Montgomery-Jacobian scalar multiplication, including its control flow, stack usage, helper calls, and constant-time table selection. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering logic.",
