iPhone XR — durable-queue worker
Open the private XR link supplied by your main phone. It pairs this Safari page to a temporary test room. No app, wallet, money, or account needed on the XR.
Waiting for a test-room link.
Keep Safari open and your XR awake for execution. The Cloudflare relay stores the queue when this phone is offline, but iOS may suspend the browser. Only a fixed SHA-256 operation is supported; no arbitrary code execution. Reports are not hardware-attested.
