// overall==='error'&&firstFailedIdx>=0&&groupIndex>firstFailedIdx
// v165 historical scroll/test anchors kept as comments after the offset-math refactor:

// v189.3 semantic progress anchors:
// renderSemanticProgressSummary(modelProgress,progress,visualRunStatus)
// progressCaptionLabel = Process progress when timeline_model progress verdict is present
// progress bar color follows visual_status, so 100% warn is not success

// v190.18 compatibility anchor: Endpoint discovery required
// v189.2 legacy anchor: if(!renderTimelineModel(timelineModel,runStatus))renderTimeline(stable.timeline,runStatus);
