The merge graph now shows impacted targets directly on nodes and edges, so you can see exactly why PRs are connected and which targets they share.
Toggle "Show targets on hover" in the graph toolbar to see per-PR impacted targets on each node, shared targets between connected nodes, and intra-batch overlaps. You can also view the full impacted target list for any PR via a "View Impacted Targets" modal with a downloadable JSON export.
