I checked for install-time hooks, subprocess launches, network or secret access, dynamic code loading, obfuscation, persistence tampering, and other supply-chain indicators; none were present.",

      "summary": "Reviewed an ARM assembly routine that zeroes the destination and then copies the selected table row into place using constant-time masking based on `idx`. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.",
