Review Summary

Reviewed the x86-64 assembly implementation of `p521_jmixadd` in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/x86_att/p521/p521_jmixadd.S`. It is a self-contained P-521 mixed Jacobian addition routine built from arithmetic macros, stack temporaries, and conditional moves; no concrete malicious or supply-chain indicators were found, and I did not see install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.
