      "summary": "Reviewed this ARM64 assembly routine for modular doubling in the P-384 field. It only loads six limbs, performs bounded arithmetic with carry/conditional select, and stores the reduced result; I found no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",

      "summary": "Reviewed the ARM assembly routine in aws-lc/third_party/s2n-bignum/arm/p384/bignum_half_p384.S. It implements a constant-time modular halving operation for reduced P-384 field elements by conditionally adding the modulus and shifting right, and I found no install hooks, network or exfiltration behavior, dynamic code loading, obfuscation, or persistence logic in this file.",
