  "summary": "Reviewed the ARM64 assembly in `aws-lc/third_party/s2n-bignum/arm/p521/p521_jmixadd.S`, which implements P-521 mixed Jacobian point addition plus local field multiply/square/sub helpers. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/packing, persistence tampering, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
