+# Curio HMS — Production deploy checklist
+
+Target: [https://curio.applaude.net/dashboard.html](https://curio.applaude.net/dashboard.html)
+
+## Pre-deploy (local)
+
+- [ ] Confirm dashboard files are saved as **UTF-8** (no `₹` / `ðŸ` in source).
+- [ ] Smoke-test locally:
+  ```powershell
+  cd c:\Users\sunde\proxmox\curaflow-hms
+  node backend/server.js
+  ```
+  Open `http://localhost:3000/dashboard.html` — sidebar must not overlap the queue table; emojis and ₹ must render correctly.
+- [ ] Bump cache-bust query strings if you changed static assets (`dashboard.css?v=`, `dashboard.js?v=` in `dashboard.html`).
+
+## Deploy (CI → registry → Kubernetes)
+
+This repo builds on **push** via `.gitea/workflows/build.yaml` (Kaniko → `192.168.8.250:5000/curio:latest`).
+
+1. **Commit and push** all changes (including `backend/server.js` UTF-8 headers and dashboard UI fixes).
+2. **Wait for the Gitea Actions build** to finish successfully.
+3. **Roll out Kubernetes** (pick one):
+   ```bash
+   # Restart pods to pull :latest
+   kubectl rollout restart deployment/curio-app -n curio
+
+   # Or patch redeploy annotation (see k8s/app.yaml)
+   kubectl apply -f k8s/app.yaml -n curio
+   kubectl rollout status deployment/curio-app -n curio
+   ```
+4. **Confirm pods are new**:
+   ```bash
+   kubectl get pods -n curio -l app=curio-app
+   kubectl logs -n curio -l app=curio-app --tail=50
+   ```
+
+## Post-deploy verification
+
+Open production in a **private/incognito** window (avoids stale cache).
+
+| Check | Expected |
+|-------|----------|
+| Nav labels | 👥 Queue, 💊 Pharmacy (not `ðŸ` / `₹`) |
+| Sidebar layout | Sidebar on the left; main content not covered |
+| Overview stats | `↑ 4 since last hour` (not `â†'`) |
+| Doctor workspace | Log in as Doctor → **Queue** → **Start Recording** visible |
+| Response headers | DevTools → Network → `dashboard.html` → `Content-Type: text/html; charset=utf-8` |
+| Recording | Chrome/Edge, allow microphone; button toggles to **Pause Scribe** |
+
+### Quick header check (PowerShell)
+
+```powershell
+(Invoke-WebRequest -Uri "https://curio.applaude.net/dashboard.html" -Method Head).Headers["Content-Type"]
+```
+
+Should include `charset=utf-8`.
+
+### Doctor role (for Zen / recording UI)
+
+In browser console on production:
+
+```javascript
+localStorage.setItem('userRole', 'DOCTOR');
+location.reload();
+```
+
+Then open **Queue** — clinical workspace with SOAP notes and **Start Recording**.
+
+## If encoding is still broken after deploy
+
+1. **Files on disk** — Re-save `dashboard.html` (and other HTML) as UTF-8 in the editor; redeploy.
+2. **Reverse proxy** — Ensure nginx/ingress does not force `charset=iso-8859-1` on static files.
+3. **CDN/cache** — Purge edge cache for `*.html`, `*.css`, `*.js`.
+4. **Hard refresh** — `Ctrl+Shift+R` on the dashboard.
+
+## Rollback
+
+```bash
+# If you tag images per release, redeploy the previous tag instead of :latest
+kubectl set image deployment/curio-app curio=192.168.8.250:5000/curio:<previous-tag> -n curio
+kubectl rollout status deployment/curio-app -n curio
+```
+
+## Files that must ship for the dashboard UX fix
+
+- `dashboard.html`
+- `dashboard.css`
+- `dashboard.js`
+- `globals.css`
+- `settings.css`
+- `backend/server.js` (UTF-8 `Content-Type` headers)
