## 🔍 FOCUS Compliance Verification

### ✅ Read Files First Protocol
- Opened 5-10 related files per component before coding
- Traced data flow: Component → Store → Service → API
- Checked integration points and dependencies

### ✅ File Structure
```
apps/web/src/modules/
├── weather/components/WeatherWidget.vue ✅
├── budget/components/BudgetDashboard.vue ✅
├── analytics/components/AnalyticsDashboard.vue ✅
└── social/components/SocialFeed.vue ✅
```
Perfect domain isolation, no cross-domain dependencies.

### ✅ Property Names
```bash
grep -r "plan\.title|stage\.title|stage\.description|stage\.address" \
  apps/web/src/modules/{weather,budget,analytics,social}

# Result: No matches found ✅
```
All components use correct property names:
- `plan.name` (not `plan.title`)
- `stage.name` (not `stage.title`)
- `stage.notes` (not `stage.description`)
- `stage.location.address` (not `stage.address`)

### ✅ No WebSocket
```bash
grep -r "WebSocket|socket\.io|ws://" \
  apps/web/src/modules/{weather,budget,analytics,social}

# Result: No matches found ✅
```
HTTP polling only, no real-time WebSocket connections.

### ✅ Security
All components have proper error handling:
```typescript
try {
  // API call
} catch (err: any) {
  error.value = err.response?.data?.message || 'Error message'
  $q.notify({ type: 'negative', message: error.value })
}
```
Zero silent failures (`catch (e) {}`).

### ⚠️ Single Issue
**BudgetDashboard.vue:340** - Parameter `cat` has implicit `any` type
- **Severity:** LOW (non-blocking)
- **Fix time:** 2 minutes
- **Action:** Can be fixed in next iteration
