It contains only fixed arithmetic on input/output registers and stack-safe ELF metadata, with no concrete indicators of install-time execution, network/exfiltration, secret harvesting, dynamic code loading, obfuscation, or persistence behavior.",

I checked for install-time hooks, subprocess or system calls, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
