+# VITE FRONTEND (src/api) KNOWLEDGE BASE
+
+## OVERVIEW
+API client layer. Wraps axios and normalizes backend responses (`{ code, msg, data }`).
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Axios wrapper | `vite-frontend/src/api/network.ts` | Sets `axios.defaults.baseURL`; adds `Authorization` header |
+| BaseURL init (WebView vs web) | `vite-frontend/src/api/network.ts` | WebView mode calls `getPanelAddresses()` |
+| Endpoint functions | `vite-frontend/src/api/index.ts` | Mostly `Network.post("/…")` |
+
+## CONVENTIONS
+- Default baseURL is `/api/v1/` (or `${VITE_API_BASE}/api/v1/`).
+- In WebView mode, baseURL is derived from the selected panel address; if unset, requests return `code: -1` with a “set panel address” message.
+- 401 responses clear localStorage and redirect to `/`.
