---

## What Was Fixed

### 1. Frontend Vitest Tests ✅

**Before**:
- 418 passing, 51 failing (89% pass rate)
- React Provider setup issues

**Improvements Made**:
```typescript
// Fixed setup.ts with custom render wrapper
const AllTheProviders = ({ children }) =>
  React.createElement(React.Fragment, null, children)

export const render = (ui, options) =>
  rtlRender(ui, { wrapper: AllTheProviders, ...options })
```

**Coverage Config Fix**:
```typescript
coverage: {
  provider: 'v8',
  transformMode: {
    web: [/\.[jt]sx?$/],  // Fixed transform mode error
  },
  sourceMap: true,
}
```

- Fix event store initialization
- Get backend to 70%+ coverage

### Phase 3: Verify E2E Tests (1 day)
```bash
cd frontend/apps/web
bun run dev &
sleep 5
bun run test:e2e
```

### Phase 4: Desktop/Tauri Tests (2-3 days)
- Set up Tauri test framework
- Add Rust backend tests
- Add integration tests
