      "summary": "Reviewed this generated AArch64 assembly file, which implements `bn_add_words` and `bn_sub_words` as straight-line big-number arithmetic loops with no install hooks, subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence logic. The file is a conventional OpenSSL/BoringSSL-style crypto primitive wrapper and I found no concrete malicious or supply-chain indicators.",

      "summary": "This target file is generated AArch64 NEON assembly for GHASH/GCM operations (`gcm_init_neon`, `gcm_gmult_neon`, `gcm_ghash_neon`) with embedded mask constants and no runtime scripting. I checked it for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain compromise indicators, and found none.",
