CARBON XIndependent public UI evaluation

Evidence edition / 23 October 2026 / en-US

Explore the evidence. See the limits.

Public discovery works across the sampled journeys. Keyboard focus restoration deserves attention. Access wording needs clarification.

Xbox Cloud Gaming was assessed while signed out in a task-scoped browser. This report connects actual checks to screenshots, DOM records, reproduction steps and residual uncertainty.

What the evidence supports

Known-title discovery, no-results feedback, search recovery, category browsing, three representative game details, direct-route reload and signed-out access links were observed. Narrow-width samples reflowed without measured document overflow.

Inspect expected vs actual →

What merits action

CX-F01: comparison dismissal left focus on BODY in two trials. CX-O02: a game’s purchase-required wording appears alongside included-subscription messaging. One transient media error recovered after reload.

What remains unknown

Real screen readers, complete contrast/zoom, actual touch devices, another engine, controlled performance and all signed-in flows remain untested. No overall quality score, certification or release recommendation is asserted.

Incomplete independent evaluation; all unproven criteria remain unresolved. Auto-selected specialist profiles in native CARBON output are framework attribution, not additional testing agents. Only one browser owner and one planning/design worker ran.

Report validation boundary

All relative file references validated; PDF pages rendered and visually inspected. HTML has responsive CSS, but desktop/mobile browser rendering of the report was not validated: the sandbox denied the loopback preview server bind. This is a report-environment limitation, not an Xbox defect. The PDF has selectable text but is not a tagged accessible PDF.
