      "summary": "Reviewed the x86-64 assembly implementation of P-384 Montgomery-Jacobian scalar multiplication in `aws-lc/third_party/s2n-bignum/x86_att/p384/p384_montjscalarmul_alt.S`. It consists of arithmetic, constant-time table selection, and local calls to add/double helpers; I found no concrete indicators of install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload execution.",
