  "summary": "Reviewed this target assembly file, which implements a fixed-size Karatsuba-style big-number multiplication routine for `aws-lc`/`s2n-bignum`. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in the file itself.",
