EF-074 · Polling Results Visualizer

The AppleTV-style large display is read-only: it renders poll results, raffle winners, and leaderboards with high contrast, stable framing, and reduced-motion support. Tier-3 tightening: poll pause edit-lock handling now references ui-conflict-resolution-modal as the shared resolution contract.

Happy path

Open display-only station.
Station passcode grants a visualizer session without attendee input controls.
Render the live module.
Poll chart, raffle, or leaderboard receives snapshots and deltas from the EFx station namespace.
Respect stage constraints.
Text is readable at distance, contrast is strong, and reduced-motion preference disables transitions.

Failure modes

Display-only live rubric

All EFx WebSocket resilience probes apply, with capability-specific display-only, contrast, and reduced-motion checks.

Stable test attributes

Visibility teeth. Visualizer regions must be genuinely visible on the large-display viewport; controls that accept input must be absent.
