      "summary": "Reviewed the generated AArch64 ChaCha20 assembly in `aws-lc/generated-src/ios-aarch64/crypto/chacha/chacha-armv8.S`, which implements `_ChaCha20_ctr32_nohw` and `_ChaCha20_ctr32_neon` as keystream generation/XOR routines for Apple AArch64. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present in this file.",
