  "summary": "Reviewed the x86-64 assembly routine in `aws-lc/third_party/s2n-bignum/x86_att/p384/bignum_montinv_p384.S`, which implements Montgomery inversion for the P-384 field using straight-line arithmetic and stack/register management. I found no concrete indicators of malicious supply-chain behavior: no install hooks, no syscalls or process spawning, no network/exfiltration, no credential access, no dynamic code loading, no obfuscation/deobfuscation payloads, and no persistence or environment tampering.",
