WHY IT NEEDS A POLICY

Why remove_qrcode_logo needs a policy

This tool modifies an existing QR code by removing its center logo. While destructive in a narrow sense, the QR code itself remains intact and functional — only the logo is removed. This is a reversible modification (the logo could be re-added), placing it in the Write category rather than Destructive. Misuse could unintentionally alter branded QR codes, giving it a medium severity.
