Review effective restrictions and configuration warnings.
Local policy linting, not a bypass-proof CSP audit. Test report-only mode and application compatibility before enforcing. No automatic deployment.
Privacy and trust boundaries
Inputs remain in this browser. No online reputation, account, DNS or remote key lookup is performed. A static inspection is not a security certification.
Use the sample to learn the workflow. Clear sensitive input after use; private exports and clipboard contents require careful handling.
