  "summary": "Reviewed the generated AArch64 ChaCha20 assembly in `pregenerated/chacha-armv8-win64.S` and found it to be a straightforward cryptographic implementation with constants, register shuffling, and plaintext/tail handling only. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
