      "summary": "Reviewed the ARM assembly implementation of `aes_hw_xts_encrypt`, which performs local AES-XTS block encryption and cipher-stealing tail handling using on-CPU crypto instructions and stack/register saves. 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.",
