Leftover-map axes name persisted leftover-map axis share when finite. The comparison variant keeps exact persisted σ and share together and right-bounds both axis captions inside the SVG.

The leftover-map graphic display sits above the pair buttons when coordinates are finite, leftover-map axes name persisted leftover-map axis share, leftover-map axis ticks name persisted coordinates, pair segments name persisted leftover-map distance, pair segments name persisted leftover-map reconstruction, pair segments name persisted leftover-map explained leftover share, pair segments name persisted leftover-map unexplained leftover share, pair segments name persisted leftover-map cross share, pair segments name persisted leftover-map unexplained leftover, pair segments name persisted leftover residual, pair segments name persisted leftover observed, pair segments name persisted leftover expected, and pair segments name persisted leftover-map rank. The pair-list note names leftover-map complete-case coverage only when leftoverMapCoverageCounts returns usable complete-case integers, leftover-map item complete-case coverage, leftover-map incomplete post coverage, and leftover-map incomplete item coverage when persisted. The grouping comparison strip names leftover-map complete-case coverage, leftover-map item complete-case coverage, leftover-map incomplete post coverage, and leftover-map incomplete item coverage with distinct comparison labels when leftoverMapCoverageCounts / leftoverMapItemCoverageCounts / leftoverMapIncompletePostCount / leftoverMapIncompleteItemCount return usable integers. | `LeftoverPairList`, `LeftoverMapPlot`, `ticket-list`, `post-badge` |
 | `Workspace/OperationsDashboard` | Compare Event and post counts, inspect external-information coverage, then open the cited source behind a claim, handover, or repeat-issue fact. `EvidenceReady`, `NarrowViewport`, `AnalysisPendingAndMissingEvidence`, `AnalysisFailed`, and `LoadError` cover populated, mobile, unavailable-evidence, analysis-pending, retryable failure, and transport-error states. | `--color-dashboard-*`, `OperationsDashboard` |
