{
  "summary": "Reviewed the `aws-lc/include/openssl/dsa.h` public DSA API header. It contains only declarations, constants, and deprecation notes for DSA signing/parsing/serialization; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden execution behavior in this file.\nReviewed this ARM64 assembly implementation of `bignum_emontredc_8n_base`, which performs local Montgomery reduction and multiply-add loops on big-integer buffers. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, and unrelated system probing, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/x86_att/curve25519/edwards25519_epdouble.S`, which is a standalone x86-64 assembly implementation of Edwards25519 point doubling using only field arithmetic macros and register/stack management. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.",
