      "summary": "Reviewed the ARM assembly implementation of P-521 Jacobian point doubling in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/arm/p521/p521_jdouble.S`. It contains only fixed arithmetic and local routine calls for field operations; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise signals.",
