# RBAC Implementation Checklist - COMPLETE ✅

## Completed Tasks

### 1. Role System Foundation ✅
- [x] Created `roles` table with 5 roles
  - super_admin
  - company_admin
  - cashier
  - meter_reader

  - Allows super_admin to bypass role checks
  - Redirects unauthenticated users

### 4. Route Protection ✅
- [x] Public routes (no auth required)
  - `/` → redirect to `/home`

  - `/apply/{slug}` → public application form
  - `/application/{reference_number}` → public application view
  - `/receipt/{billingId}` → public receipt view

- [x] Authenticated routes (auth + verified required)
  - `/dashboard` → role-based dashboard

- [x] Super Admin routes
  - `/companies` → company management

  - `/staff` → staff management
  - `/company/profile` → company profile
  - `/company/settings` → company settings

- [x] Meter Reader routes
  - `/record-meter` → record meter readings
  - `/my-meter-readings` → view own readings

- [x] Customer routes
  - `/my-billings` → view personal billings
  - `/my-payments` → view payment history

### 5. Controller Authorization ✅

  - Company-based authorization

- [x] PaymentController
  - Company-filtered queries

### 6. Dashboard Implementation ✅
- [x] DashboardController with 5 dashboard methods
  - `superAdminDashboard()` → system overview
  - `companyAdminDashboard()` → company management
  - `cashierDashboard()` → payment collection
  - `meterReaderDashboard()` → meter reading operations
  - `customerDashboard()` → personal billing view

- [x] Dashboard views created
  - `dashboards/super-admin.blade.php`
  - `dashboards/company-admin.blade.php`
  - `dashboards/cashier.blade.php`
  - `dashboards/meter-reader.blade.php`
  - `dashboards/customer.blade.php`

### 7. Authorization Policies ✅
- [x] BillingPolicy
  - view, create, update, delete authorization
  - Company-based access control
  
- [x] Other policies
  - ClientPolicy
  - PaymentPolicy
  - etc.

### 8. Activity Logging ✅

  - Records before/after values
  - User identification
  - Route tracking

- [x] ActivityLog model and migration
- [x] LogController for viewing logs
- [x] Route: `/logs` for super_admin and company_admin

### 9. Multi-Tenancy Support ✅
- [x] Company-level data isolation
  - Company Admin sees only their company
  - Cashier sees only their company
  - Super Admin can see all or filter by company

- [x] Company relationships
  - User → Company (many-to-one, optional for super_admin)
  - Client → Company (many-to-one)
  - Billing → Client → Company (chain)

### 10. Testing & Verification ✅
- [x] Routes properly configured
- [x] Middleware working correctly
- [x] Authorization checks in place
