Every browser 'online' event reset the display host to its loading state and mounted the module again: a fresh viewer session, a fresh stage, and every cached object URL released, on each Wi-Fi blip. And a device revoked while its display was open never noticed; it kept playing cached content and polling 403s until someone reloaded the page. The host now re-resolves its descriptor in the background (ADR 0043) and only replaces the frame when the answer actually changed: a new version or principal remounts, a refusal returns the screen to pairing (ADR 0036), and any other failure keeps the running display. A module request refused with 401/403 prompts the same revalidation, throttled, so revocation is noticed within one heartbeat. The offline indicator waits ten seconds before appearing, so a momentary blip shows nothing, and no longer names the platform on a lobby wall. Co-Authored-By: Claude Opus 5.5 <[email protected]>
