      "summary": "Reviewed `src/cpu/arm/fuchsia.rs`, which contains Fuchsia-specific ARM feature detection by calling the Zircon `zx_system_get_features` API and mapping returned CPU capability bits to local feature flags. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed the ARM Linux CPU feature detection code in `src/cpu/arm/linux.rs`. It only reads `getauxval`/HWCAP bits to derive local CPU capability flags for aarch64 and 32-bit ARM, and I found no concrete signs of install hooks, network or credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malicious behavior.",

      "summary": "Reviewed `src/cpu/arm/windows.rs`, which only performs Windows ARM CPU feature detection via `IsProcessorFeaturePresent` and maps the result to AES, PMull, and SHA-256 capability flags.
