Drive the Witness Wall, right here.
Like the Lab, for the living-room screen: an Apple TV emulator you steer with the arrow keys or the on-screen remote. Try three profiles — Home, Business and Apartment: a doorbell over your show, a monitoring board, a peek through the peephole. The native Apple TV app is built and tested, but not on the App Store yet.
The real Wall is a web app that works today — open it in your browser; it also packages for Samsung and LG TVs and casts to Chromecast. Its checks come from a verifier that actually runs, never a hardcoded string.
Demo fleet — not connected to a kernel · connect yours
Drive it like an Apple TV
Hover the screen to engage the keyboard (so arrow keys still scroll the page elsewhere). Then explore the three profiles:
- Home — pick Watch a show, then Ring doorbell: the alert takes over your movie as a picture-in-picture — the "your food's here" moment, no phone needed. View shows a coarse peek; raw video never leaves the device.
- Business — flip Glance → Monitor for the heavy ops board: a live feed you can acknowledge, zone status, open incidents wired to dispute-pack, a shift/hours/compliance banner, and a multi-site rollup.
- Apartment — a battery Canary on the peephole. Hit Knock, then Peek to see who's there from the couch — built for anyone who can't easily get to the door.
Coarse events only — a zone and a time, never a face. Flip it on and an alert slides in over whatever's on screen (try it during the screensaver). On a real Apple TV they show in the app and over its screensaver; a HomeKit bridge carries them over other apps.
Connect your fleet experimental
This really fetches a kernel over HTTP and shows its Canaries in place of the demo fleet. Hit Try a live demo kernel, or enter your own kernel's address — a browser can't scan your LAN. It keeps watching the three well-known ones (canary.local:8099, the kernel's own canary.local:8799, then canary.local — a fresh Canary answers there with no hub at all), so when one shows up you get to flip the switch.
Not connected — showing the demo fleet.
Why can't it just find them automatically?
Browsers deliberately can't do mDNS/Bonjour discovery or scan your network, and a page served over https:// can't reach a device that only speaks http:// on your LAN (mixed-content is blocked). So real discovery works when: your kernel exposes a CORS-enabled endpoint over https, or you open this page on the same LAN over http, or you run the SecuraCV desktop app, which does the mDNS discovery natively and bridges it to the UI. When a kernel answers, your real fleet — names and online state — replaces the demo data here; the chain chip stays the emulator's placeholder. The real Wall at /tv shows a verdict only when a hub serves an evidence envelope, which no shipping hub or Canary does today — against every real source it is presence-only and says so. On a Home Assistant add-on hub, enable the 8799 host port in the add-on's Network settings first (it ships disabled) and type http://<hub>:8799 — with the port.
A browser emulator of the native app, which is built and tested but not on the App Store yet. Its checkmarks are staged; the witness kernel, the signed record and the camera integrations it depicts are real.
