# Remaining Fixes Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Resolve every outstanding issue documented in `docs/REMAINING_FIXES.md` except the global removal of `Model::unguard()`.

**Architecture:** Re-align the API route URIs with the test suite's expected `/owner/*`, `/customer/*`, and `/employee/*` prefixes; tighten authorization/ownership checks; serialize concurrency-sensitive refund/payment flows; guard reservation lifecycle transitions; backfill missing tests; and update build/tooling/docs to a passing, consistent state.

**Tech Stack:** Laravel 13.x, PHP 8.4, Laravel Sanctum, Spatie Laravel Permission, Spatie Media Library, OwenIt Auditing, Pest PHP, Laravel Pint, Vite.

---

## Context & Non-Goals

- **Do NOT remove `Model::unguard()`** in `app/Providers/AppServiceProvider.php`. The user explicitly excluded this.
- The project currently has **104 failing tests**, mostly because route URIs in `routes/api.php` do not match the `/api/v1/owner/*`, `/api/v1/customer/*`, and `/api/v1/employee/*` prefixes used throughout the test suite.
- `AppServiceProvider.php` contained unresolved Git merge-conflict markers; those have already been cleaned up.
- Several `REMAINING_FIXES` entries are already partially fixed in code but still need route/test alignment or documentation refresh.

---

## Task 1: Fix API Route URIs and Middleware Alignment

**Files:**
- Modify: `routes/api.php`
- Test: `tests/Feature/Authorization/RouteMiddlewareTest.php`, `tests/Feature/Auth/ProtectedRoutesTest.php`, `tests/Feature/FullFlowTest.php`

- [ ] **Step 1: Read `routes/api.php` and identify all mismatched URIs**

  Mismatches found:
  - Owner-scoped resources use bare URIs (`buildings`, `units`, `facilities`, `employees`, `transactions`, `invoices`, `promo-codes`, `reservations`, `unit-availabilities`) but tests call `/api/v1/owner/*`.
  - Customer reservation resources use `/api/v1/reservations` but tests call `/api/v1/customer/reservations`.
  - Employee on-arrival/check-in/check-out use `/api/v1/reservations/...` but tests call `/api/v1/employee/reservations/...`.

- [ ] **Step 2: Restructure route groups with URI prefixes and correct middleware**

  Rewrite the authenticated groups in `routes/api.php` so each role group uses a URI prefix:

  ```php
  // Owner routes
  Route::middleware(['auth:sanctum', 'verified', 'role:owner'])->prefix('owner')->group(function () {
      Route::get('dashboard', [OwnerDashboardController::class, 'index']);
      Route::get('profile', [OwnerProfileController::class, 'show']);
      Route::put('profile', [OwnerProfileController::class, 'update']);

      Route::apiResource('buildings', BuildingController::class)
          ->middleware('can:manage_buildings');
      Route::apiResource('facilities', FacilityController::class)
          ->middleware('can:manage_buildings');
      Route::put('buildings/{building}/disable', [BuildingController::class, 'disable'])
          ->middleware('can:manage_buildings');
      Route::post('buildings/{building}/photos', [BuildingController::class, 'addPhotos'])
          ->middleware('can:manage_buildings');
      Route::post('buildings/{building}/units/bulk', [UnitController::class, 'bulkStore'])
          ->middleware('can:manage_buildings');
      Route::get('buildings/{building}/facilities', [BuildingController::class, 'facilities'])
          ->middleware('can:manage_buildings');
      Route::post('buildings/{building}/facilities', [BuildingController::class, 'assignFacilities'])
          ->middleware('can:manage_buildings');
      Route::delete('buildings/{building}/facilities/{facility}', [BuildingController::class, 'unassignFacility'])
          ->middleware('can:manage_buildings');
      Route::get('buildings/{building}/units', [UnitController::class, 'index'])
          ->middleware('can:manage_buildings');

      Route::apiResource('units', UnitController::class)
          ->middleware('can:manage_units');
      Route::post('units/{unit}/photos', [UnitController::class, 'addPhotos'])
          ->middleware('can:manage_units');
      Route::get('units/{unit}/facilities', [UnitController::class, 'facilities'])
          ->middleware('can:manage_units');
      Route::post('units/{unit}/facilities', [UnitController::class, 'assignFacilities'])
          ->middleware('can:manage_units');
      Route::delete('units/{unit}/facilities/{facility}', [UnitController::class, 'unassignFacility'])
          ->middleware('can:manage_units');

      Route::apiResource('employees', EmployeeController::class)
          ->except(['update'])
          ->middleware('can:manage_employees');
      Route::put('employees/{employee}', [EmployeeController::class, 'update'])
          ->middleware('can:manage_employees');

      Route::post('reservations/{reservation}/check-in', [ReservationController::class, 'checkIn']);
      Route::post('reservations/{reservation}/check-out', [ReservationController::class, 'checkOut']);

      Route::apiResource('invoices', InvoiceController::class)->except(['store', 'update']);
      Route::apiResource('promo-codes', PromoCodeController::class);
      Route::apiResource('transactions', TransactionController::class)->only(['index', 'store', 'show']);
      Route::apiResource('unit-availabilities', UnitAvailabilityController::class)->only(['index']);
      Route::post('unit-availabilities/block', [UnitAvailabilityController::class, 'block']);
      Route::post('unit-availabilities/unblock', [UnitAvailabilityController::class, 'unblock']);
      Route::apiResource('reservations', ReservationController::class);
  });

  // Employee routes
  Route::middleware(['auth:sanctum', 'verified', 'role:owner|employee'])
      ->prefix('employee')
      ->group(function () {
          Route::post('reservations/on-arrival/prepare', [ReservationController::class, 'prepareOnArrival']);
          Route::post('reservations/on-arrival/validate', [ReservationController::class, 'validateOnArrival']);
          Route::post('reservations/on-arrival/verify', [PendingCustomerController::class, 'verifyOtp']);
          Route::post('reservations/{reservation}/check-in', [ReservationController::class, 'checkIn']);
          Route::post('reservations/{reservation}/check-out', [ReservationController::class, 'checkOut']);
      });

  // Customer routes
  Route::middleware(['auth:sanctum', 'verified', 'role:customer'])->prefix('customer')->group(function () {
      Route::get('profile', [CustomerController::class, 'show']);
      Route::put('profile', [CustomerController::class, 'update']);
      Route::put('profile/password', [CustomerController::class, 'updatePassword']);
      Route::apiResource('reservations', ReservationController::class);
  });

  // Admin routes — keep existing admin URIs (already prefixed or unique)
  Route::middleware(['auth:sanctum', 'verified', 'role:super_admin|admin'])->prefix('admin')->group(function () {
      Route::get('dashboard', [AdminDashboardController::class, 'index']);
      Route::apiResource('cities', CityController::class)->except(['index', 'show']);
      Route::apiResource('countries', CountryController::class)->except(['index', 'show']);
      Route::apiResource('currencies', CurrencyController::class)->except(['index', 'show']);
      Route::apiResource('regions', RegionController::class)->except(['index', 'show']);
      Route::get('owners', [OwnerProfileController::class, 'index']);
      Route::get('notifications', [NotificationController::class, 'all']);
      Route::get('employees', [EmployeeController::class, 'all']);
  });
  ```

  Remove the old owner/employee/customer groups that used non-prefixed URIs. Keep public catalog routes (`units`, `countries`, etc.) as they are.

- [ ] **Step 3: Verify route list matches test expectations**

  Run:
  ```bash
  php artisan route:list | grep -E 'owner/|customer/|employee/'
  ```

  Expected: `/api/v1/owner/buildings`, `/api/v1/customer/reservations`, `/api/v1/employee/reservations/on-arrival/...`, etc.

- [ ] **Step 4: Run authorization tests**

  Run:
  ```bash
  php artisan test tests/Feature/Authorization/RouteMiddlewareTest.php tests/Feature/Auth/ProtectedRoutesTest.php
  ```

  Expected: PASS (or at least no 404 failures from missing routes).

- [ ] **Step 5: Commit**

  ```bash
  git add routes/api.php
  git commit -m "fix(routes): align owner/customer/employee URI prefixes with test suite"
  ```

## Task 2: Fix Production Blockers / Fatal Errors

**Files:**
- Modify: `app/Http/Controllers/CountryController.php`
- Modify: `app/Http/Controllers/Api/Owner/EmployeeController.php`
- Test: `tests/Feature/FullFlowTest.php`, existing location tests

- [ ] **Step 1: Fix `CountryController::store` and `update` fatal errors**

  In `app/Http/Controllers/CountryController.php`:

  ```php
  public function store(CountryRequest $request)
  {
      $this->authorize('create', Country::class);

      $data = $request->validated();
      $currency = Currency::where('code', $data['currency_code'])->firstOrFail();

      $country = Country::create([
          'name' => $data['name'],
          'currency_id' => $currency->id,
          'time_difference' => $data['time_difference'] ?? 0,
      ]);

      return CountryResource::make($country->load(['currency', 'cities']));
  }

  public function update(CountryUpdateRequest $request, Country $country)
  {
      $this->authorize('update', $country);

      $data = $request->validated();

      if (isset($data['currency_code'])) {
          $currency = Currency::where('code', $data['currency_code'])->firstOrFail();
          $data['currency_id'] = $currency->id;
      }

      unset($data['currency_code']);

      $country->update($data);

      return CountryResource::make($country->load(['currency', 'cities']));
  }
  ```

- [ ] **Step 2: Fix `EmployeeController::index` crash for employees**

  In `app/Http/Controllers/Api/Owner/EmployeeController.php`:

  ```php
  public function index()
  {
      $this->authorize('viewAny', Employee::class);

      $ownerId = auth()->user()->owner?->id
          ?? auth()->user()->employee?->owner_id;

      $employees = Employee::where('owner_id', $ownerId)
          ->with(['user', 'owner'])
          ->paginate(10);

      return EmployeeResource::collection($employees);
  }
  ```

  Also ensure `EmployeePolicy::viewAny` allows employees to view employees of their owner.

- [ ] **Step 3: Run FullFlowTest and location smoke tests**

  ```bash
  php artisan test tests/Feature/FullFlowTest.php
  ```

- [ ] **Step 4: Commit**

  ```bash
  git add app/Http/Controllers/CountryController.php app/Http/Controllers/Api/Owner/EmployeeController.php
  git commit -m "fix(controllers): repair CountryController fatal errors and EmployeeController index crash"
  ```

## Task 3: Close Security Holes

**Files:**
- Modify: `app/Http/Controllers/Api/AuthController.php`
- Modify: `app/Services/OtpService.php`
- Modify: `app/Http/Controllers/UnitController.php`
- Modify: `app/Http/Requests/UnitRequest.php`
- Modify: `app/Http/Controllers/TransactionController.php`
- Modify: `app/Policies/TransactionPolicy.php`
- Modify: `app/Http/Controllers/InvoiceController.php`
- Modify: `app/Http/Controllers/PromoCodeController.php`
- Modify: `app/Http/Controllers/Api/Customer/CustomerController.php`
- Modify: `app/Http/Controllers/Api/Owner/OwnerProfileController.php`
- Modify: `app/Http/Controllers/Api/NotificationController.php`
- Modify: `app/Policies/OwnerPolicy.php`
- Modify: `app/Policies/NotificationPolicy.php`
- Modify: `config/request-docs.php`
- Modify: `config/auth.php`
- Modify: `config/sanctum.php`
- Test: `tests/Feature/Auth/*`, `tests/Feature/Authorization/*`

- [ ] **Step 1: Make login stateless and remove session usage**

  In `app/Http/Controllers/Api/AuthController.php`:

  ```php
  use Illuminate\Support\Facades\Hash;

  public function login(LoginRequest $request)
  {
      $credentials = $request->only('password');

      if ($request->has('email')) {
          $credentials['email'] = $request->validated('email');
      } else {
          $credentials['phone'] = $request->validated('phone');
      }

      $user = User::where($credentials)->first();

      if (! $user || ! Hash::check($request->validated('password'), $user->password)) {
          return response()->json(['message' => 'Invalid credentials'], 401);
      }

      if (! $user->is_verified) {
          return response()->json(['message' => 'Account not verified.'], 403);
      }

      return $this->issueAuthToken($user);
  }
  ```

  Remove `Auth::logout()` calls and `use Illuminate\Support\Facades\Auth;` if no longer needed (or keep it only for `Auth::guard('web')->logout()` in `issueAuthToken`).

  Update `config/auth.php`:
  ```php
  'defaults' => [
      'guard' => env('AUTH_GUARD', 'api'),
      'passwords' => env('AUTH_PASSWORD_BROKER', 'users'),
  ],
  ```

  Update `config/sanctum.php`:
  ```php
  'guard' => ['api'],
  ```

- [ ] **Step 2: Stop exposing OTPs and add brute-force/attempt limiting**

  In `app/Services/OtpService.php` add attempt tracking:

  ```php
  public function send(string $key): string
  {
      $otp = str_pad((string) random_int(0, 999999), 6, '0', STR_PAD_LEFT);

      Cache::put($this->cacheKey($key), $otp, now()->addMinutes(self::TTL_MINUTES));
      Cache::forget($this->attemptsKey($key));

      return $otp;
  }

  public function verify(string $key, string $otp): bool
  {
      $attemptsKey = $this->attemptsKey($key);
      $attempts = Cache::get($attemptsKey, 0);

      if ($attempts >= 5) {
          return false;
      }

      if (Cache::get($this->cacheKey($key)) !== $otp) {
          Cache::put($attemptsKey, $attempts + 1, now()->addMinutes(self::TTL_MINUTES));

          return false;
      }

      Cache::forget($this->cacheKey($key));
      Cache::forget($attemptsKey);

      return true;
  }

  public function attemptsKey(string $key): string
  {
      return "otp_attempts:$key";
  }
  ```

  In `AuthController`, stop returning `otp` in registration and resend responses unless in local/testing:

  ```php
  private function otpResponse(string $message, ?string $otp = null): \Illuminate\Http\JsonResponse
  {
      $payload = ['message' => $message];

      if ($otp && app()->environment('local', 'testing')) {
          $payload['otp'] = $otp;
      }

      return response()->json($payload);
  }
  ```

  Use this helper in `registerOwner`, `registerCustomer`, and `resendOtp`. Also fix `resendOtp` undefined `$otp` by restructuring:

  ```php
  public function resendOtp(ResendOtpRequest $request)
  {
      $phone = $request->validated('phone');
      $email = $request->validated('email');

      $user = $this->findUserByContact($phone, $email);

      if (! $user || $user->is_verified) {
          return response()->json(['message' => 'If the account exists and is unverified, an OTP was sent.']);
      }

      $otp = OtpService::send($this->contactKey($phone, $email));

      return $this->otpResponse('If the account exists and is unverified, an OTP was sent.', $otp);
  }
  ```

- [ ] **Step 3: Enforce building ownership in `UnitController::store`**

  In `app/Http/Requests/UnitRequest.php`:

  ```php
  use Illuminate\Validation\Rule;

  public function rules(): array
  {
      $ownerId = auth()->user()?->owner?->id;

      return [
          'building_id' => [
              $this->isMethod('POST') ? 'required' : 'sometimes',
              'exists:buildings,id',
              Rule::when($ownerId, Rule::exists('buildings', 'id')->where('owner_id', $ownerId)),
          ],
          // ... rest unchanged
      ];
  }
  ```

  Alternatively, validate in the controller:

  ```php
  public function store(UnitRequest $request)
  {
      $this->authorize('create', Unit::class);

      $data = $request->safe()->except(['photos']);
      $building = Building::findOrFail($data['building_id']);

      if ($building->owner_id !== auth()->user()->owner?->id) {
          abort(403, 'You do not own this building.');
      }

      // ... existing logic
  }
  ```

- [ ] **Step 4: Enforce reservation ownership in `TransactionController::store`**

  Before using `$reservation`, verify it belongs to the current user's building:

  ```php
  $reservation = Reservation::findOrFail($data['reservation_id']);

  $ownerId = $reservation->unit?->building?->owner_id;
  $user = auth()->user();

  if ($user->isOwner() && $user->owner?->id !== $ownerId) {
      abort(403, 'This reservation does not belong to you.');
  }

  if ($user->isEmployee() && $user->employee?->owner?->id !== $ownerId) {
      abort(403, 'This reservation does not belong to your owner.');
  }
  ```

- [ ] **Step 5: Scope `InvoiceController::index` and `PromoCodeController::index` to tenant**

  `InvoiceController::index`:
  ```php
  public function index()
  {
      $this->authorize('viewAny', Invoice::class);

      $user = auth()->user();
      $query = Invoice::with('reservation.unit.building')
          ->where('received', 'owner');

      if ($user->isOwner()) {
          $query->whereHas('reservation.unit.building', fn ($q) => $q->where('owner_id', $user->owner?->id));
      } elseif ($user->isEmployee()) {
          $query->whereHas('reservation.unit.building', fn ($q) => $q->where('owner_id', $user->employee?->owner?->id));
      }

      return InvoiceResource::collection($query->latest()->paginate(10));
  }
  ```

  `PromoCodeController::index`:
  ```php
  public function index()
  {
      $this->authorize('viewAny', PromoCode::class);

      $user = auth()->user();
      $query = PromoCode::query();

      if ($user->isOwner()) {
          $query->where('owner_id', $user->owner?->id);
      } elseif ($user->isEmployee()) {
          $query->where('owner_id', $user->employee?->owner_id);
      }

      return PromoCodeResource::collection($query->paginate(20));
  }
  ```

- [ ] **Step 6: Add missing policy authorizations**

  - `CustomerController::index`: add `$this->authorize('viewAny', Customer::class);`.
  - `OwnerProfileController::index`: add `$this->authorize('viewAny', Owner::class);`.
  - `NotificationController::index`: add `$this->authorize('viewAny', Notification::class);` (or rely on `auth()->user()->notifications()` if policy allows).

  Add `viewAny` to `OwnerPolicy`:
  ```php
  public function viewAny(User $user): bool
  {
      return $user->isAdmin();
  }
  ```

  Restrict `NotificationPolicy::viewAny`:
  ```php
  public function viewAny(User $user): bool
  {
      return $user->isAdmin();
  }
  ```

- [ ] **Step 7: Gate request-docs behind environment flag**

  In `config/request-docs.php`:
  ```php
  'enabled' => env('REQUEST_DOCS_ENABLED', true),
  ```

  In `.env.example` add:
  ```
  REQUEST_DOCS_ENABLED=false
  ```

- [ ] **Step 8: Run auth/security tests**

  ```bash
  php artisan test tests/Feature/Auth tests/Feature/Authorization
  ```

- [ ] **Step 9: Commit**

  ```bash
  git add app/Http/Controllers/Api/AuthController.php app/Services/OtpService.php app/Http/Controllers/UnitController.php app/Http/Requests/UnitRequest.php app/Http/Controllers/TransactionController.php app/Policies/TransactionPolicy.php app/Http/Controllers/InvoiceController.php app/Http/Controllers/PromoCodeController.php app/Http/Controllers/Api/Customer/CustomerController.php app/Http/Controllers/Api/Owner/OwnerProfileController.php app/Http/Controllers/Api/NotificationController.php app/Policies/OwnerPolicy.php app/Policies/NotificationPolicy.php config/request-docs.php config/auth.php config/sanctum.php .env.example
  git commit -m "fix(security): stateless login, OTP hardening, ownership checks, tenant scoping"
  ```

## Task 4: Fix Data-Integrity and Business-Logic Risks

**Files:**
- Modify: `app/Http/Controllers/TransactionController.php`
- Modify: `app/Services/ReservationService.php`
- Modify: `app/Services/UnitAvailabilityService.php`
- Modify: `app/Console/Commands/ReleaseExpiredPendingReservations.php`
- Modify: `app/Http/Controllers/Api/Owner/EmployeeController.php`
- Modify: `app/Http/Controllers/InvoiceController.php`
- Modify: `app/Http/Controllers/ReservationController.php`
- Modify: `app/Models/Transaction.php`, `app/Models/Invoice.php`, `app/Models/Receipt.php`
- Test: `tests/Feature/WalletPaymentRefundTest.php`, `tests/Feature/ReservationFixesTest.php`

- [ ] **Step 1: Serialize refund flow in `TransactionController::store`**

  Move the customer lock and refund computation to the top of the transaction, before any rows are inserted:

  ```php
  $transaction = DB::transaction(function () use ($data, $reservation, $invoice, $receipt, $isRefund, $isWalletPayment, $isRealCustomer) {
      unset($data['reservation_id']);

      $invoice = Invoice::where('id', $invoice->id)->lockForUpdate()->firstOrFail();
      $customer = Customer::where('id', $reservation->customer_id)->lockForUpdate()->firstOrFail();

      if ($isRefund) {
          $totalPaid = Transaction::where('invoice_id', $invoice->id)
              ->where('type', 'payment')->lockForUpdate()
              ->sum('amount') ?? 0;

          $totalRefunded = Transaction::where('invoice_id', $invoice->id)
              ->where('type', 'refund')->lockForUpdate()
              ->sum('amount') ?? 0;

          $availableRefund = $totalPaid - $totalRefunded;

          if ($data['amount'] > $availableRefund) {
              abort(422, 'Refund amount exceeds the paid balance.');
          }
      }
      // ... rest of existing logic
  });
  ```

  Remove the duplicate pre-check outside the transaction (lines 69–97) so the locked computation is the single source of truth.

- [ ] **Step 2: Guard reservation lifecycle transitions**

  `ReservationService::updateReservation`: reject edits to `checked_out`/`canceled` and block unit/date changes on `checked_in`:

  ```php
  public function updateReservation(Reservation $reservation, array $data): void
  {
      if (in_array($reservation->status, ['checked_out', 'canceled'], true)) {
          throw ValidationException::withMessages([
              'status' => ['Cannot modify a completed or cancelled reservation.'],
          ]);
      }

      // ... existing logic, but also block unit changes when checked_in
      if ($reservation->status === 'checked_in' && $unitChanged) {
          throw ValidationException::withMessages([
              'unit_id' => ['Cannot change the unit after check-in.'],
          ]);
      }

      // ... rest
  }
  ```

  `ReservationController::destroy`: already checks `status != 'pending'`; ensure it returns a proper JSON response from within the closure.

- [ ] **Step 3: Prevent `blockDates()` from overwriting pending holds**

  In `UnitAvailabilityService::blockDates`, change the conflict check to treat `booked` rows (real or pending) as conflicts:

  ```php
  $conflict = $availabilities->contains(
      fn (UnitAvailability $availability) => $availability->status === 'booked'
  );
  ```

  Also update the `where` clause in the update query to only block `available` rows.

- [ ] **Step 4: Make `ReleaseExpiredPendingReservations` atomic**

  ```php
  public function handle(): int
  {
      $count = 0;

      PendingReservation::expired()->lockForUpdate()->cursor()->each(function (PendingReservation $pendingReservation) use (&$count) {
          DB::transaction(function () use ($pendingReservation) {
              UnitAvailabilityService::releasePendingDates($pendingReservation->id);
              $pendingReservation->update([
                  'status' => 'expired',
                  'promo_code_id' => null,
              ]);
          });
          $count++;
      });

      $this->info("Released {$count} expired pending reservation(s).");

      return self::SUCCESS;
  }
  ```

- [ ] **Step 5: Fix `UnitAvailabilityService::releaseDates()` null safety**

  ```php
  public function releaseDates(int $reservationId): void
  {
      $firstBooked = UnitAvailability::where('reservation_id', $reservationId)
          ->orderBy('date', 'asc')
          ->lockForUpdate()
          ->first();

      if (! $firstBooked) {
          return;
      }

      if ($firstBooked->date <= Carbon::now()->toDateString()) {
          throw new Exception("Reservation already started and can't be cancelled");
      }

      UnitAvailability::where('reservation_id', $reservationId)->update([
          'status' => 'available',
          'reservation_id' => null,
      ]);
  }
  ```

- [ ] **Step 6: Add decimal casts to financial models**

  `Transaction`:
  ```php
  protected function casts(): array
  {
      return [
          'amount' => 'decimal:2',
      ];
  }
  ```

  `Invoice` and `Receipt`:
  ```php
  protected function casts(): array
  {
      return [
          'price' => 'decimal:2',
          'total_price' => 'decimal:2',
          'discount' => 'decimal:2',
          'net_price' => 'decimal:2',
          'paid_amount' => 'decimal:2',
          'remaining_amount' => 'decimal:2',
      ];
  }
  ```

- [ ] **Step 7: Handle invoice soft-delete with existing transactions**

  In `InvoiceController::destroy`, either detach transactions or abort with a message. Choose the safer option: do not allow deleting invoices that have transactions:

  ```php
  public function destroy(Invoice $invoice)
  {
      $this->authorize('delete', $invoice);

      if ($invoice->transactions()->exists()) {
          return response()->json(['message' => 'Cannot delete an invoice that has transactions.'], 422);
      }

      $invoice->delete();

      return response()->json([
          'message' => 'Invoice deleted successfully.',
          'deleted' => ['id' => $invoice->id],
      ]);
  }
  ```

  Ensure `Invoice::transactions()` relation exists.

- [ ] **Step 8: Run refund and reservation tests**

  ```bash
  php artisan test tests/Feature/WalletPaymentRefundTest.php tests/Feature/ReservationFixesTest.php
  ```

- [ ] **Step 9: Commit**

  ```bash
  git add app/Http/Controllers/TransactionController.php app/Services/ReservationService.php app/Services/UnitAvailabilityService.php app/Console/Commands/ReleaseExpiredPendingReservations.php app/Http/Controllers/ReservationController.php app/Http/Controllers/InvoiceController.php app/Models/Transaction.php app/Models/Invoice.php app/Models/Receipt.php
  git commit -m "fix(data-integrity): serialize refunds, guard reservation transitions, atomic pending release, decimal casts"
  ```

## Task 5: Fix API Contracts, Validation, and Resources

**Files:**
- Modify: `app/Http/Controllers/PromoCodeController.php`
- Modify: `app/Http/Controllers/Api/AuthController.php`
- Modify: `app/Http/Controllers/CountryController.php`
- Modify: `app/Http/Requests/PromoCodeRequest.php`
- Modify: `routes/api.php`
- Test: `tests/Feature/Validation/FormRequestsTest.php`, `tests/Feature/ReservationFixesTest.php`

- [ ] **Step 1: Standardize create/update response wrapping**

  In `PromoCodeController::store`, return the resource directly:

  ```php
  return PromoCodeResource::collection($promoCodes)->response()->setStatusCode(201);
  ```

- [ ] **Step 2: Prevent promo-code ownership transfer**

  In `PromoCodeRequest::rules()`, remove `owner_id` from the rules. In `PromoCodeController::update`, remove the manual `owner_id` comparison (no longer needed).

- [ ] **Step 3: Fix `AuthController::resendOtp` undefined `$otp`**

  Already covered in Task 3.

- [ ] **Step 4: Add `CustomerController::index` and `destroy` routes**

  Under admin prefix:
  ```php
  Route::apiResource('customers', CustomerController::class)->only(['index', 'destroy']);
  ```

- [ ] **Step 5: Run validation tests**

  ```bash
  php artisan test tests/Feature/Validation/FormRequestsTest.php
  ```

- [ ] **Step 6: Commit**

  ```bash
  git add app/Http/Controllers/PromoCodeController.php app/Http/Requests/PromoCodeRequest.php routes/api.php app/Http/Controllers/Api/Customer/CustomerController.php
  git commit -m "fix(api): standardize responses, prevent promo-code transfer, route customers"
  ```

## Task 6: Fix Performance / Architecture Nits

**Files:**
- Modify: `app/Http/Controllers/UnitController.php`
- Modify: `app/Http/Controllers/BuildingController.php`
- Modify: `app/Http/Controllers/FacilityController.php`
- Modify: `app/Services/ReservationReminderScheduler.php`
- Modify: `app/Http/Controllers/BuildingController.php`
- Test: `tests/Feature/UnitShowAvailabilityTest.php`, `tests/Feature/BuildingUnitFiltersTest.php`

- [ ] **Step 1: Add date-window filtering to unit availability queries**

  `UnitController::index` already uses a `year` scope. Ensure `UnitController::show` defaults to a reasonable window when no `from`/`to`/`year` is provided (already defaults to current year). Keep the year scope.

- [ ] **Step 2: Avoid loading all unit media in `BuildingController::index`**

  Remove `units.media` from the `with()` call in `index`. Keep `media` for building photos.

- [ ] **Step 3: Paginate `FacilityController::index`**

  ```php
  return FacilityResource::collection(Facility::paginate(20));
  ```

- [ ] **Step 4: Bulk-update scheduled notification cancellations**

  In `ReservationReminderScheduler::cancelPendingFor`:

  ```php
  public function cancelPendingFor(Reservation $reservation): void
  {
      ScheduledNotification::pendingForReservation($reservation->id)->update(['cancelled_at' => now()]);
  }
  ```

- [ ] **Step 5: Make `BuildingController::filter()` private**

  ```php
  private function filter($query, ListingFilterRequest $request)
  ```

- [ ] **Step 6: Commit**

  ```bash
  git add app/Http/Controllers/UnitController.php app/Http/Controllers/BuildingController.php app/Http/Controllers/FacilityController.php app/Services/ReservationReminderScheduler.php
  git commit -m "perf(architecture): reduce eager loads, paginate facilities, bulk update reminders"
  ```

## Task 7: Fix Build, Tooling, and Documentation

**Files:**
- Modify: `vite.config.js`, `package.json`
- Modify: `.env.example`
- Modify: `composer.json`
- Modify: `app/Services/DashboardMetrics.php`
- Modify: `docs/REMAINING_FIXES.md`, `PROJECT_PROGRESS.md`
- Modify: `tests/Unit/ExampleTest.php`, `tests/Feature/ExampleTest.php`
- Run: `vendor/bin/pint`

- [ ] **Step 1: Restore frontend build**

  The project has no `resources/` directory. Since there is no frontend, remove the Vite input references and keep a minimal config:

  ```js
  import { defineConfig } from 'vite';

  export default defineConfig({});
  ```

  Update `package.json` scripts:
  ```json
  "scripts": {
      "build": "echo 'No frontend assets to build'",
      "dev": "echo 'No frontend dev server'"
  }
  ```

  Remove frontend dev dependencies (`@tailwindcss/vite`, `tailwindcss`, `laravel-vite-plugin`, `concurrently`) or leave them; the important change is that `npm run build` exits 0.

- [ ] **Step 2: Update `.env.example`**

  Append:
  ```
  AUDITING_ENABLED=true
  SANCTUM_STATEFUL_DOMAINS=localhost,localhost:3000,127.0.0.1,127.0.0.1:8000,::1
  REQUEST_DOCS_ENABLED=false
  APP_TIMEZONE=UTC
  AUTH_GUARD=api
  ```

- [ ] **Step 3: Fix `composer.json` test script**

  ```json
  "test": [
      "@php artisan config:clear --ansi",
      "@php artisan test"
  ]
  ```

- [ ] **Step 4: Remove DashboardMetrics song lyrics comment**

  Delete lines 174–178 in `app/Services/DashboardMetrics.php`.

- [ ] **Step 5: Remove placeholder tests**

  Delete `tests/Unit/ExampleTest.php`. Keep or update `tests/Feature/ExampleTest.php` to assert the root JSON message:

  ```php
  it('returns the API health message', function () {
      $response = $this->get('/');

      $response->assertOk()
          ->assertJson(['message' => 'API is working']);
  });
  ```

- [ ] **Step 6: Run Laravel Pint**

  ```bash
  vendor/bin/pint
  ```

- [ ] **Step 7: Update documentation**

  Update `docs/REMAINING_FIXES.md` to reflect the current state: mark resolved items, update test counts, and note the route alignment. Update `PROJECT_PROGRESS.md` to remove stale references to `ContactSetting` and polymorphic `owner_type/owner_id`.

- [ ] **Step 8: Commit**

  ```bash
  git add vite.config.js package.json .env.example composer.json app/Services/DashboardMetrics.php tests/Feature/ExampleTest.php docs/REMAINING_FIXES.md PROJECT_PROGRESS.md
  git commit -m "chore(build): fix npm build, env example, composer script, docs, pint"
  ```

## Task 8: Backfill Missing Feature Tests

**Files:**
- Create/Modify: `tests/Feature/PromoCodeGenerationTest.php`, `tests/Feature/BuildingUpdateDeleteTest.php`, `tests/Feature/UnitDeleteTest.php`, `tests/Feature/LocationCrudTest.php`

- [ ] **Step 1: Add promo-code generation test**

  ```php
  it('allows an owner to generate promo codes', function () {
      $owner = // ... create verified owner
      $response = $this->actingAs($owner->user, 'sanctum')
          ->postJson('/api/v1/owner/promo-codes', [
              'discount_type' => 'percentage',
              'discount_value' => 10,
              'usage_limit' => 5,
              'expires_at' => now()->addDays(7)->toDateString(),
              'count' => 3,
          ]);

      $response->assertCreated()
          ->assertJsonCount(3, 'data');
  });
  ```

- [ ] **Step 2: Add building update/delete tests**

  Test owner can update and delete their building; non-owner receives 403.

- [ ] **Step 3: Add unit delete test**

  Test owner can delete their unit; non-owner receives 403; deleting a unit with reservations fails.

- [ ] **Step 4: Add full location CRUD tests**

  Test admin can create/update/delete country, city, region, currency; non-admin receives 403.

- [ ] **Step 5: Commit**

  ```bash
  git add tests/Feature/PromoCodeGenerationTest.php tests/Feature/BuildingUpdateDeleteTest.php tests/Feature/UnitDeleteTest.php tests/Feature/LocationCrudTest.php
  git commit -m "test: backfill promo-code, building/unit delete, location CRUD tests"
  ```

---

## Task 9: Final Verification

- [ ] **Step 1: Run the full test suite**

  ```bash
  php artisan test
  ```

  Expected: 0 failures.

- [ ] **Step 2: Run Pint in test mode**

  ```bash
  vendor/bin/pint --test
  ```

  Expected: no style violations.

- [ ] **Step 3: Verify npm build**

  ```bash
  npm run build
  ```

  Expected: exits 0.

- [ ] **Step 4: Update `REMAINING_FIXES.md` final test count**

  Set the test count line to the actual passing count.

- [ ] **Step 5: Commit**

  ```bash
  git add docs/REMAINING_FIXES.md
  git commit -m "docs: finalize remaining fixes and test counts"
  ```
