{
  "summary": "Reviewed `aws-lc/crypto/obj/obj_xref.c`, which is a small lookup table and helper routines for mapping signature algorithm NIDs to digest/public-key NIDs. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `aws-lc/ssl/ssl_text.cc`, which is a C++ helper that formats and prints `SSL_SESSION` fields to a `BIO` for debugging/introspection. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/asn1/tasn_typ.c`, which is a macro-driven ASN.1 type helper source defining string, object, boolean, and sequence/set wrappers. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, hidden subprocess execution, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this ARM NEON assembly routine, which performs a constant-time table row copy into `z` using masking and sequential loads/stores. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed this x86-64 assembly routine implementing `bignum_double_p384`, which doubles a 384-bit field element and conditionally reduces it modulo the P-384 prime using only register arithmetic and memory writes to the output buffer. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
