{
  "summary": "Reviewed the ARM assembly in `aws-lc/third_party/s2n-bignum/arm/p521/p521_jadd.S`, which implements P-521 Jacobian point addition with local field multiply/square/sub routines and constant-time conditional moves. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
