**Analysis:** Selected node override works correctly regardless of zoom level.

### Test 6: Edge LOD Transitions

**Target:** Progressive simplification
**Result:** Smooth
**Status:** ✅ PASS

### Test 7: Maximum Node Count

**Target:** Usable at 10k, degraded at 20k
**Result:** As expected
**Status:** ✅ PASS

**Details:**

## Technical Implementation

### Viewport Culling

**Algorithm:** Spatial filtering with Set-based lookups

**Key Features:**

- Deterministic edge culling
- Stable viewport boundaries
- O(1) node lookups
- Efficient memory usage

**Code Example:**

```typescript
const visibleNodes = useMemo(() => {
  const viewport = reactFlowInstance?.getViewport();
  if (!viewport) return nodes;

  const buffer = 500;
  return nodes.filter((node) => isInViewport(node, viewport, buffer));
}, [nodes, reactFlowInstance]);
```

### LOD System

**Node Detail Levels:**

1. **SkeletonPill** (zoom < 0.3): Colored box only
2. **SimplePill** (zoom 0.3-0.6): Minimal detail
3. **MediumPill** (zoom 0.6-1.2): Moderate detail
4. **RichNodePill** (zoom > 1.2): Full detail

**Edge Detail Levels:**

1. **Tier 1** (zoom > 1.0): Full bezier curves with labels
2. **Tier 2** (zoom 0.5-1.0): Straight lines with labels
3. **Tier 3** (zoom 0.2-0.5): Minimal straight lines
4. **Tier 4** (zoom < 0.2): Ultra-minimal hairlines

**Dynamic Node Type Selection:**

```typescript
const nodeTypes = useMemo(() => {
  const zoom = reactFlowInstance?.getViewport()?.zoom || 1;

  if (zoom > 1.2) return { default: RichNodePill };
  else if (zoom > 0.6) return { default: MediumPill };
  else if (zoom > 0.3) return { default: SimplePill };
  else return { default: SkeletonPill };
}, [reactFlowInstance]);
```
