One-click end-to-end demo

One click. Full flow. Signed end to end.

Live demoRun this demo at sandbox.kyeprotocol.com/demo.html; the same governed flow also runs in the terminal and the lab.

Runs a sample Action Request through every production Worker in the KYE™ runtime chain — kye-gateway → kye-pdp → back to your browser — and shows the response from each hop. No sign-up. No install. Uses the same public URLs you would use from your own code.
