# 2.6 — Frontend: React Flow topology graph (GREEN)

Phase: 2 — Topology (Surface B)
Stage: GREEN

Depends on: [2.2](2.2-topology-component-test.md), [2.4](2.4-api-topology.md), [2.5](2.5-api-stream.md)

- [ ] Frontend: React Flow, force layout, node -> namespace -> workload
- [ ] Fetch from [/api/topology](../app/api/topology/route.ts) and [/api/stream](../app/api/stream/route.ts) (mock) instead of importing `clusterMock` directly

## Verify

```bash
# trigger a mock delta via /api/stream, observe graph update in <5s without reloading
curl -N http://localhost:3000/api/stream
```
