      "summary": "Reviewed the ARM assembly implementation of P-521 Jacobian scalar multiplication in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/arm/p521/p521_jscalarmul.S` and checked for install-time hooks, subprocess spawning, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence; none were present. The file appears to be self-contained finite-field/elliptic-curve arithmetic with constant-time table selection and no concrete supply-chain indicators.",
