Jev Document Classifier

These are Jev Playground’s local demo thresholds, not TypeSafe recommendations or validated production policy. Display only · no new request. Suspicious content takes precedence; confidentiality does not change the status.

One same-origin request, three questions. Categories are judgments; any subsequent action belongs to separate application code.
