Diagnostic visibility · current policy

Technical diagnostics are aggregated on this page so driver authors and tool builders can compare what multiple testers saw, including Windows and Linux runs for the same VID:PID. They use closed result names and path-redacted errors; the only private field is the tester's free-text response notes.

What's NOT on this page

The one private field

The only thing kept off this page is the per-effect free-text notes — what the tester typed in the answer text box. Everything else — capability flags, supported effects, OS breakdown, chip labels, result codes, failed effects, run errors — can be published in aggregate or as a latest-per-platform snapshot.
