      "summary": "Reviewed the ARM assembly routine in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/arm/p521/bignum_mod_n521_9.S`, which performs fixed modular reduction for P-521 using register arithmetic and stores the result. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.",

      "summary": "Reviewed an ARM64 assembly routine that reduces a 9-limb integer modulo the P-521 field prime. The file only performs in-register arithmetic and stores the result; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence.",
