Positions stored in `position?: { x: number; y: number }` (line 27). No new fields needed on the graph model. + +2. **Manual position coexistence:** Architecture explicitly states: "Manual repositioning must coexist with auto-layout" (line 42). ELK layout's `resolvePositions()` already skips `manuallyPositioned` nodes (elk-layout.ts line 133-134). This was pre-implemented in Story 2.2. + +3. **Selection state for Epic 3 badge system:** Architecture specifies that "selected nodes appear as badge candidates (for Epic 3 integration)". The `selectedNodeIds` array in the Zustand store provides this bridge. + +4. **No position overrides map:** Architecture suggests "Manual position overrides, if any, should be stored as a separate overrides map" (line 156). However, the implementation already stores `manuallyPositioned` directly on DiagramNode along with `position` — this is simpler and matches the existing pattern. The dev agent should follow the existing implementation, NOT create a separate overrides map. + +5. **Component Structure:** All changes are in existing files (`DiagramCanvas.tsx`, `useGraphStore.ts`, `graph-converter.ts`, `globals.css`). No new component files needed for this story. + +### Current State Analysis — What Already Works + +**Already implemented (from Stories 2.1-2.8):** + +| Feature | Status | Where | +|---------|--------|-------| +| `manuallyPositioned` field on DiagramNode | Defined | `graph.ts` line 28 | +| `position` field on DiagramNode | Defined | `graph.ts` line 27 | +| ELK skips `manuallyPositioned` nodes | Implemented | `elk-layout.ts` lines 133-134 | +| `onNodesChange` with `applyNodeChanges` | Implemented | `useGraphStore.ts` lines 53-56 | +| `onEdgesChange` with `applyEdgeChanges` | Implemented | `useGraphStore.ts` lines 58-60 | +| `--node-selected` CSS variable | Defined | `globals.css` lines 16, 44 | +| `--edge-selected` CSS variable | Defined | `globals.css` lines 20, 47 | +| Nodes draggable (default) | Active | `` default prop | +| Elements selectable (default) | Active | `` default prop | +| Shift+drag rectangle selection | Active | `` default behavior | +| BFS path highlighting on click | Active | `DiagramCanvas.tsx` lines 238-286 | +| `onPaneClick` clear highlight | Active | `DiagramCanvas.tsx` line 298 | + +**What's MISSING (this story's scope):** + +| Feature | What Needs to Happen | +|---------|---------------------| +| `manuallyPositioned` flag set on drag | Add `onNodeDragStop` handler in DiagramCanvas | +| `manuallyPositioned` preserved in roundtrip | Fix `flowNodeToGraphNode` in graph-converter.ts | +| Selection visual feedback (CSS) | Add `.react-flow__node.selected` and `.react-flow__edge.selected` styles | +| Drag visual feedback (CSS) | Add `.react-flow__node.dragging` style | +| `selectedNodeIds` in store | Add to GraphState for Epic 3 bridge | +| `onSelectionChange` wiring | Track selection state in store | + +### `onNodeDragStop` Handler Pattern + +```typescript +// In DiagramCanvas.tsx — CanvasInner component +const handleNodeDragStop = useCallback( + (_event: React.MouseEvent, _node: Node, draggedNodes: Node[]) => { + const store = useGraphStore.getState();
