+
+## Troubleshooting Guide — Where to Look
+
+### "The call desk isn't working"
+**File:** `src/pages/call-desk.tsx`
+This is the orchestrator. It uses `useSip()` for call state, `useWorklist()` for the task queue, and renders either `ActiveCallCard` (in-call) or `WorklistPanel` (idle). Start here, then drill into whichever child component is misbehaving.
+
+### "Calls aren't connecting / SIP errors"
+**File:** `src/providers/sip-provider.tsx` + `src/state/sip-state.ts`
+Check `VITE_SIP_*` env vars. Ozonetel SIP WebSocket runs on **port 444** — VPNs block it. If WebSocket hangs at "connecting", turn off VPN. Also check browser console for SIP.js registration errors.
+
+### "Worklist not loading / empty"
+**File:** `src/hooks/use-worklist.ts`
+This polls `GET /api/worklist` on the sidecar every 30s. Open browser Network tab → filter for `/api/worklist`. Common causes: sidecar is down, auth token expired, or agent name doesn't match any assigned leads.
+
+### "Missed calls not appearing / sub-tabs empty"
+**File:** `src/components/call-desk/worklist-panel.tsx`
+Missed calls come from the sidecar worklist response. The sub-tabs filter by `callbackstatus` field. If all sub-tabs are empty, the sidecar ingestion may not be running (check sidecar logs for `MissedQueueService`).
+
+### "Disposition / appointment not saving"
+**File:** `src/components/call-desk/active-call-card.tsx` → `handleDisposition()`
+Posts to sidecar `POST /api/ozonetel/dispose`. Errors are caught silently (non-blocking). Check browser Network tab for the dispose request/response, then check sidecar logs.
+
+### "Login broken / Failed to fetch"
+**File:** `src/pages/login.tsx` + `src/lib/api-client.ts`
+Login calls `apiClient.login()` → sidecar `/auth/login` → platform GraphQL. Most common cause: wrong `VITE_API_URL` (built with localhost instead of production URL). **Always set env vars at build time.**
+
+### "UI component looks wrong"
+**Files:** `src/components/base/` (primitives), `src/components/application/` (complex)
+These come from the Untitled UI library. Design tokens are in `src/styles/theme.css`. Brand colors were rebuilt from logo blue `rgb(32, 96, 160)`.
+
+### "Navigation / role-based access"
+**File:** `src/components/layout/sidebar.tsx`
+Navigation groups are defined per role (admin, cc-agent, executive). Routes are registered in `src/main.tsx`.
+
+## Data Flow
+
+```
+User action
+    │
+    ▼
+Component (e.g. ActiveCallCard)
+    │
+    ├──▶ Sidecar REST API (via apiClient.post/get)
+    │       e.g. /api/ozonetel/dispose, /api/worklist
+    │
+    ├──▶ Platform GraphQL (via apiClient.graphql)
+    │       e.g. leads, appointments, patients queries
+    │
+    └──▶ SIP.js (via useSip() hook)
+            Call control: answer, hangup, mute, hold
+```
+
+**Key pattern:** The frontend talks to TWO backends:
+1. **Sidecar** (REST) — for Ozonetel telephony operations and worklist
+2. **Platform** (GraphQL) — for entity CRUD (leads, appointments, patients)
+
+## Conventions
+
+- **File naming**: kebab-case (`worklist-panel.tsx`)
+- **Colors**: Semantic tokens only (`text-primary`, `bg-brand-section`)
+- **Icons**: `@fortawesome/pro-duotone-svg-icons` + `faIcon()` wrapper in `src/lib/icon-wrapper.ts`
+- **React Aria**: Always prefix imports (`Button as AriaButton`)
+- **Transitions**: `transition duration-100 ease-linear`
+
+## Git Workflow
+
+- `dev` — active development
+- `master` — stable baseline
+- Always build with production env vars before deploying
