+## Phase 1 patterns
+
+Patterns that emerged during Canvas Phase 1 — follow these in subsequent phases:
+
+- **`ApiError` class** with `status` property for structured HTTP error handling (`api/client.ts`)
+- **`spliceEdge`** for atomic node-on-edge insertion — removes the old edge and creates two new edges in one store update (`graphSlice.ts`)
+- **`useGraphStore.getState()`** inside callbacks to avoid stale closures from Zustand subscriptions
+- **`useNodePlacement`** hook encapsulating singleton guards + edge splitting for drop/stamp operations
+- **Global toast** via `useUIStore.getState().showToast()` — callable from anywhere (store, hooks, not just components)
+- **`encodeURIComponent(id)`** on all API path params to handle special characters in graph IDs
+
