  handleRejectTimesheet: (id: string) => void
  handleAdjustTimesheet: (id: string, adjustmentData: TimesheetAdjustment) => void
  // ... 11 more properly typed methods
}

Status: ✅ Complete and correct

---

2. NewNotification Interface ✅

Location: /src/lib/types.ts (Lines 342-348)

  type: NotificationType
  priority: NotificationPriority
  title: string
  message: string
  relatedId?: string
}

Status: ✅ Complete and correct

---

3. use-app-actions Hook ✅

Location: /src/hooks/use-app-actions.ts

Fixes Confirmed:

• ✅ Line 25: addNotification: (notification: NewNotification) => void
• ✅ Line 26: Return type ): AppActions
• ✅ Line 71: adjustment: TimesheetAdjustment (no any)
• ✅ Line 83: adjustment.newRate ?? t.rate ?? 0 (proper null coalescing)
• ✅ Line 325: creditNote: CreditNote parameter properly typed

Status: ✅ All fixes in place, no any types

---

4. ViewRouter Component ✅

Location: /src/components/ViewRouter.tsx (Line 65)

interface ViewRouterProps {
  // ...other props
  actions: AppActions  // ✅ Properly typed, not 'any'
}

Status: ✅ Properly typed

---

5. use-app-data Hook ✅

Location: /src/hooks/use-app-data.ts (Line 57)

// ✅ CORRECT - No unsafe type assertion
const monthlyPayroll = payrollRuns.reduce((sum, pr) => 
  sum + (pr.totalAmount || 0), 0)

// ❌ OLD CODE (removed):
// sum + (pr.totalAmount || (pr as any).totalGross || 0), 0)

Status: ✅ Unsafe assertion removed

🚀 Recommendations

Immediate: None Required ✅

All TypeScript type safety issues have been resolved. No immediate action needed.

Ongoing Monitoring

1. Prevent Regression: Watch for new any types in code reviews
2. Expand Type Coverage: Consider stricter TypeScript config in future
3. Type Testing: Add type tests when test infrastructure is implemented

Future Enhancements (Low Priority)

1. Enable strict: true in tsconfig.json
2. Add JSDoc comments for complex types
3. Create type utility helpers for common patterns
