  "summary": "Reviewed the ARM64 assembly implementation of `bignum_montsqr_p521` in `aws-lc/third_party/s2n-bignum/arm/p521/bignum_montsqr_p521.S`. The file is straight-line finite-field arithmetic for P-521 Montgomery squaring, and I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.",
