{
  "summary": "Reviewed this ARM64 assembly helper, which only loads two words from `[x1]`, performs a fixed sequence of multiply/add-with-carry operations, and writes results to registers. I found no concrete indicators of hidden execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed `builder/cc_builder/win_aarch64.rs`, which only defines a static list of Windows AArch64 crypto assembly source paths for the build system. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `builder/prebuilt-nasm.sh`, a small build helper that parses `-o`, derives a basename, and copies a matching local prebuilt `.obj` from `builder/prebuilt-nasm/` to the requested output path. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed aws-lc/include/openssl/siphash.h, a small OpenSSL-compatible public header that only declares the SIPHASH_24 API and includes no implementation logic. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed this 26-line ARM64 assembly file and found it to be straight-line integer/vector arithmetic with register moves and carry propagation only. I checked for install-time hooks, hidden subprocess execution, network or exfiltration, credential access, dynamic code loading, obfuscation/decoding, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
