 ## Telemetry architecture
 
-The repository includes a full Prometheus → ClickHouse metric pipeline as a git submodule at `telemetry/`. Each ZeaVis Edu service exposes a `GET /metrics` endpoint:
+The telemetry stack lives as a git submodule at `telemetry/` (repo `MythEclipse/Telemetry`). Architecture:
+
+| Layer | Service | Role |
+|-------|---------|------|
+| Collector & Storage | **Prometheus** | Metric scraping & TSDB storage |
+| System metrics | **Node Exporter** | CPU, memory, disk per host |
+| Query | **Query Proxy** | REST API over Prometheus HTTP API |
+| Visualization | **Grafana** | OSS dashboard & PromQL |
+| Entry point | **Telemetry UI** | nginx + Vue 3 SPA |
+
+Data flow: Node Exporter → Prometheus scrape (every 15s) → Grafana (PromQL) / Query Proxy (/api/metrics).
+
+Each ZeaVis Edu service exposes a `GET /metrics` endpoint:
 
 - **Web app** (`apps/web`): In dev mode, a Vite plugin serves client-side session metrics (page views, Web Vitals). In production, nginx proxies `/metrics` to the API service. Source: `apps/web/src/lib/telemetry.ts`, `apps/web/vite-plugin-metrics.ts`.
 - **API** (`apps/api`): Uses `prom-client` for Node.js default metrics plus custom HTTP, auth, classification, and diagnosis counters/histograms. Source: `apps/api/src/lib/telemetry.ts`, exposed via `apps/api/src/routes/metrics.ts`.
 - **ML service** (`apps/ml-service`): Uses the `prometheus` Rust crate for HTTP metrics, prediction counts, and model load status. Source: `apps/ml-service/src/telemetry.rs`.
 
-All three share the `zeavis_` metric prefix and are scraped by the Telemetry Prometheus instance via `file_sd_configs` (see `telemetry/prometheus/targets/zeavis-edu.json`).

-**IMPORTANT — Production architecture:** ZeaVis Edu apps and the Telemetry stack run on **separate VPS instances** connected via **Tailscale** (mesh VPN). Prometheus scrapes the API and ML service through their **Tailscale IPs** (e.g. `100.x.x.a:3000`), not via Docker hostnames. The target file `telemetry/prometheus/targets/zeavis-edu.json` has `__CHANGE_ME__` placeholders — before deploying, replace with the actual Tailscale IPs of the app VPS.

+## Android Google OAuth (Tauri) — known issues & fixes
+
+The Tauri Android app uses Chrome's `intent://` protocol to bounce back from Google's OAuth browser page. Three bugs were found and fixed in commit `c75cba2`:
+
+### 1. API base URL falls back to `http://tauri.localhost`
+
+**Symptom:** Google login button navigates to `http://tauri.localhost/api/v1/auth/google` → 404.
+**Root cause:** `auth-form.tsx` used `import.meta.env.VITE_API_BASE_URL || window.location.origin`. In Android WebView the origin is `http://tauri.localhost` (Vite dev server), not the API server.
+**Fix:** Import shared `apiBaseUrl` from `api-client.ts` which already has the correct fallback: `import.meta.env.VITE_API_BASE_URL ?? 'https://zeavisedu.asepharyana.my.id'`.
+
+### 2. `deep-link:get_current` IPC promise orphaned on SPA navigation
+
+**Symptom:** `Cannot read properties of undefined (reading 'runCallback')` floods log; OAuth never completes.
+**Root cause:** `plugin:deep-link|get_current` returns a JS promise that stays pending. When React Router's `navigate()` changes the URL (SPA, no page reload), the Tauri IPC bridge invalidates the pending callback reference — but the promise never resolves or rejects cleanly, so `.runCallback` is undefined.
+**Fix (cold start):** `get_current` resolves via `window.location.href = target` (full reload). At boot there is no SPA state to lose, so a hard redirect is safe.
+**Fix (warm start / `deep-link://new-url` event):** Store target in `sessionStorage` + dispatch a custom DOM event. A `<DeepLinkRouterHandler>` root layout route listens for the event and calls React Router's `navigate()`, keeping SPA state alive.
+
+### 3. LoginPage `?token=` effect does not re-run on SPA navigation
+
+**Symptom:** App navigates to `/login?token=xxx` but stays on the login form.
+**Root cause:** The `useEffect` that reads `?token` and exchanges it for a session only listed `[setUser, queryClient, navigate]` as deps. React Router SPA navigation changes `location.search` but does not remount the component — so the effect never re-runs.
+**Fix:** Added `location.search` to the effect's dependency array. Also added `visibilitychange` and `focus` event listeners as a backup — when the user returns from the Google OAuth browser tab, the app picks up the token from the URL even if the deep-link plugin's event was missed.
+
+### Design rule for Tauri deep-link handlers
+
+- **Cold start** (app was not running) → safe to use `window.location.href` (full reload). The React app has just booted, no state to lose.
+- **Warm start** (app was running, user returns from system browser) → use React Router `navigate()` via custom events / sessionStorage. Do NOT use `window.location.href` — it triggers a full page unload which orphan Tauri IPC promises.

 ## Notes for future changes
