  "summary": "Reviewed the x86-64 P-521 Jacobian point-add assembly in `aws-lc/third_party/s2n-bignum/x86_att/p521/p521_jadd_alt.S`. It is a self-contained big-number arithmetic routine with register/stack setup and constant-time field operations; I found no concrete signs of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
