Run detail — task panel, prompt, verdict, diff, race timing

Inspecting a run shows a task line under the run id (the same summary as the list), and each step shows a verdict card — the judge method, the winning worker, and the agreement % when available — above the winning output. Each worker row shows its elapsed time plus a small ████/░░░░ race bar scaled to the fastest finisher in that step, so you can see who won the race at a glance. Press p to expand the full prompt of the step that owns the selected worker; press d to open the winning output of that step in a full scrollable diff viewer with +/-/@@ coloring. A CLI worker row also shows a host-sandbox badge — [sb:seatbelt] (or bubblewrap/docker) when it ran confined to its worktree, or a yellow [sb:none] when it ran with full host access (see HOST_SANDBOX_MODE).
