  "summary": "Hand-written x86-64 assembly implementing P-521 Jacobian point doubling for AWS-LC/s2n-bignum, consisting of deterministic field-arithmetic macros and a single exported routine. I checked for install hooks, subprocess or system calls, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
