How to use: keep chrome://extensions → VIYUH BDR → service worker open. Click open on a case → it loads the real test page → the extension should do what the Expected column says. Mark PASS (matched) or FAIL (didn't). POS = must detect · NEG = must stay silent · LIVE = needs a real host / backend (see README). Detections also land on your dashboard scoped to this PC's BDR id.
VIYUH BDR Tester Suite · cases load from your existing fixtures under bdr/testing/ · serve via the test server (e.g. :4005), not file://
