      "summary": "Reviewed the AArch64 assembly in `aws-lc/third_party/s2n-bignum/arm/fastmul/bignum_emontredc_8n.S`, which implements in-place extended Montgomery reduction over 8-word blocks and only performs arithmetic plus register save/restore. I found no concrete indicators of install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.",
