  "summary": "Reviewed this target assembly file as a generated ARM/NEON SHA-1 implementation for Apple/iOS ARM builds. I found no concrete supply-chain or malicious indicators in the file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/decoding pipelines, or persistence behaviors, only crypto round logic and static constants.",
