# Story 0.2: Rename Folders to Declarations in Backend

Status: done

<!-- Note: Validation is optional. Run validate-create-story for quality check before dev-story. -->

## Story

As a developer,
I want all backend PHP code to use "Declaration" terminology instead of "Folder",
so that the codebase is consistent with the database and professional domain language.

## Acceptance Criteria

1. **Given** the database migration from Story 0.1 has been applied, **When** the backend rename is complete, **Then** the `Folder` model is renamed to `Declaration` with updated table name, relationships, and fillable attributes
2. **And** the `FolderInvitation` model is renamed to `DeclarationInvitation` with updated table, fillable (`declaration_id`), and relationships
3. **And** `FolderController` is renamed to `DeclarationController` with updated route model binding
4. **And** `FolderMediaController` is renamed to `DeclarationMediaController`
5. **And** `FolderMessageController` is renamed to `DeclarationMessageController`
6. **And** `FolderMentionController` is renamed to `DeclarationMentionController`
7. **And** all Form Request classes (`StoreFolderRequest`, `UpdateFolderRequest`, `StoreFolderMessageRequest`, `StoreFolderMentionRequest`) are renamed with "Declaration" prefix
8. **And** all Enums (`FolderStatus`, `FolderType`, `FolderPriority`) are renamed to `DeclarationStatus`, `DeclarationType`, `DeclarationPriority`
9. **And** all Mail classes (`FolderConfirmationMail`, `FolderFileRequestMail`, `FolderInviteMail`, `FolderSituationMail`, `FolderTextMessageMail`) are renamed with "Declaration" prefix
10. **And** the `FolderMentionNotification` is renamed to `DeclarationMentionNotification`
11. **And** the `ValidateFolderInvitation` middleware is renamed to `ValidateClientPortalToken`
12. **And** all routes in `web.php` are updated from "folders" to "declarations" and the middleware alias is updated
13. **And** `bootstrap/app.php` middleware alias is updated from `folder.invitation` to `client-portal`
14. **And** `FolderFactory` is renamed to `DeclarationFactory`
15. **And** all related models (`Client`, `Workspace`, `Message`) have their relationships and references updated
16. **And** all controllers referencing Folder (`DashboardController`, `ClientController`, `WorkspaceController`, client portal controllers) are updated
17. **And** all Blade email templates in `resources/views/emails/folder-*.blade.php` are renamed to `declaration-*`
18. **And** Spatie polymorphic columns (`media.model_type`, `activity_log.subject_type`) storing `App\Models\Folder` are updated to `App\Models\Declaration` via a data migration
19. **And** the `DatabaseSeeder` is updated to use Declaration terminology
20. **And** all existing feature tests are updated and passing

  - [x] 14.1: Run `grep -r "Folder" app/ database/ routes/ tests/ resources/views/emails/ --include="*.php" --include="*.blade.php"` — confirm zero "Folder" references remain (except in migration file names which are historical)
  - [x] 14.2: Run `php artisan route:list` to verify all routes are registered correctly
  - [x] 14.3: Run `composer test` — all tests pass

## Dev Notes

### Critical Architecture Constraints

- **Database engine:** MySQL 8.4 (production) / SQLite for local dev — Story 0.1 already renamed tables
- **Multi-tenant:** All models are workspace-scoped via `workspace_id` column
- **Spatie media_library:** `media.model_type` stores FQCN `App\Models\Folder` — MUST be updated via data migration (Task 12) to `App\Models\Declaration`
- **Spatie activity_log:** `activity_log.subject_type` stores `App\Models\Folder` — same data migration
- **No morph map:** The codebase has NO `Relation::morphMap()` — polymorphic types store full class names. The data migration in Task 12 handles this. Do NOT register a morph map as a shortcut — keep consistent with existing pattern
- **Laravel 12:** No `doctrine/dbal` needed for schema operations
- **Docker Compose:** Everything runs under Docker — use `docker compose exec laravel.test` prefix for artisan/composer commands

### Rename Strategy — Order of Operations

**The order matters to avoid broken imports during the rename process:**

1. **Enums first** (no dependencies on other renamed files)
2. **Models second** (depend on enums, depended on by everything else)
3. **Related models** (depend on renamed models)
4. **Form Requests** (depend on enums)
5. **Controllers** (depend on models, enums, requests)
6. **Mail classes** (depend on models)
7. **Blade templates** (referenced by mail classes)
8. **Notification** (depends on models)
9. **Middleware** (depends on models)
10. **Routes** (depend on controllers, middleware)
11. **Factory + Seeder** (depend on models, enums)
12. **Polymorphic data migration** (standalone DB operation)
13. **Tests** (depend on everything)

| `resources/views/emails/folder-mention.blade.php` | `resources/views/emails/declaration-mention.blade.php` |
| `tests/Feature/Folder/` | `tests/Feature/Declaration/` |

### Variable and Method Rename Patterns

Within the renamed files AND referencing files, apply these renames consistently:

| Old Pattern | New Pattern |
|---|---|
| `$folder` | `$declaration` |
| `$folders` | `$declarations` |
| `$folderTypes` | `$declarationTypes` |
| `$folderIndex` | `$declarationIndex` |
| `$numFolders` | `$numDeclarations` |
| `folder_id` | `declaration_id` |
| `folder_title` | `declaration_title` |
| `folder_invitation` (request attr) | `declaration_invitation` |
| `authorizeFolder()` | `authorizeDeclaration()` |
| `folderTypeLabels()` | `declarationTypeLabels()` |
| `folderStatusLabels()` | `declarationStatusLabels()` |
| `folderPriorityLabels()` | `declarationPriorityLabels()` |
| `createInvitation()` | Keep name (context-independent) |
| `getOrCreateInvitation()` | Keep name (context-independent) |
| `updateFolderStatusAndConfirmation()` | `updateDeclarationStatusAndConfirmation()` |
| `sendEmailForMessage()` | Keep name (context-independent) |
| `route('folders.*')` | `route('declarations.*')` |
| `'emails.folder-*'` (view refs) | `'emails.declaration-*'` |

### Controllers That Reference Folder (Update Only, Not Rename)

These controllers import `Folder`/`FolderStatus` and need import + usage updates:

- **`DashboardController.php`** — imports `Folder`, `FolderStatus`. Uses folder queries for dashboard stats (assignedFolders, overdue, dueSoon, etc.)
- **`ClientController.php`** — uses `Folder` model via `$client->folders()` relationship
- **`WorkspaceController.php`** — imports `Folder`, `FolderStatus`. Uses folder counts for workspace stats
- **`Client/UploadController.php`** — imports `FolderStatus`, gets `folder` from request attribute
- **`Client/ConfirmController.php`** — imports `FolderStatus`, gets `folder` from request attribute

### Polymorphic Data Migration — Critical

The `media` and `activity_log` tables store `App\Models\Folder` as FQCN in `model_type` / `subject_type` columns. After renaming the model class, existing rows will point to a non-existent class.

**Migration `2026_03_11_000002_update_polymorphic_folder_to_declaration.php`:**

```php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Support\Facades\DB;

return new class extends Migration
{
    public function up(): void
    {
        DB::table('media')
            ->where('model_type', 'App\\Models\\Folder')
            ->update(['model_type' => 'App\\Models\\Declaration']);

        DB::table('activity_log')
            ->where('subject_type', 'App\\Models\\Folder')
            ->update(['subject_type' => 'App\\Models\\Declaration']);
    }

    public function down(): void
    {
        DB::table('media')
            ->where('model_type', 'App\\Models\\Declaration')
            ->update(['model_type' => 'App\\Models\\Folder']);

        DB::table('activity_log')
            ->where('subject_type', 'App\\Models\\Declaration')
            ->update(['subject_type' => 'App\\Models\\Folder']);
    }
};
```

**Migration timestamp:** `2026_03_11_000002` — MUST be after `2026_03_11_000001` (the rename migration from Story 0.1).

### Client Portal Middleware Rename

The middleware `ValidateFolderInvitation` → `ValidateClientPortalToken` is an **intentional semantic rename** (not just s/Folder/Declaration). The AC from the epics specifies this name. Update both:

1. `app/Http/Middleware/ValidateClientPortalToken.php` (file + class name)
2. `bootstrap/app.php` alias: `'client-portal' => ValidateClientPortalToken::class`
3. `routes/web.php` middleware usage: `->middleware('client-portal')`

Inside the middleware, also rename:
- `FolderInvitation` → `DeclarationInvitation`
- `$invitation->folder` → `$invitation->declaration`
- Request attributes: `folder_invitation` → `declaration_invitation`, `folder` attribute → `declaration`

In client portal controllers (`Client/UploadController.php`, `Client/ConfirmController.php`), update:
- `$request->attributes->get('folder_invitation')` → `$request->attributes->get('declaration_invitation')`
- `$request->attributes->get('folder')` → `$request->attributes->get('declaration')`

### Factory Rename — Model Binding

When renaming `FolderFactory` → `DeclarationFactory`, Laravel auto-discovers factories by convention (`App\Models\Declaration` → `Database\Factories\DeclarationFactory`). The `HasFactory` trait on `Declaration` model will resolve correctly if the factory class name matches. No explicit `newFactory()` override needed.

### Blade Template Content Updates

When renaming blade templates, also update **variable names inside** them:
- `$folder->title` → `$declaration->title`
- `$folder->client->name` → `$declaration->client->name`
- Any other `$folder` or `$invitation->folder` references → `$declaration` / `$invitation->declaration`

### Route Name Changes Impact

After renaming routes from `folders.*` to `declarations.*`, update all `route()` helper calls:
- `route('folders.index')` → `route('declarations.index')`
- `route('folders.create')` → `route('declarations.create')`
- `route('folders.store')` → `route('declarations.store')`
- `route('folders.show', $folder)` → `route('declarations.show', $declaration)`
- `route('folders.edit', $folder)` → `route('declarations.edit', $declaration)`
- `route('folders.update', $folder)` → `route('declarations.update', $declaration)`
- `route('folders.destroy', $folder)` → `route('declarations.destroy', $declaration)`
- `route('folders.messages.store', $folder)` → `route('declarations.messages.store', $declaration)`
- `route('folders.media.store', $folder)` → `route('declarations.media.store', $declaration)`
- `route('folders.media.download', [...])` → `route('declarations.media.download', [...])`
- `route('folders.mentions.store', $folder)` → `route('declarations.mentions.store', $declaration)`

### Previous Story Intelligence (Story 0.1)

Key learnings from Story 0.1 that apply here:
- **SQLite vs MySQL:** Use Laravel's `Schema` facade methods exclusively, never raw SQL
- **Docker commands:** Run all artisan/test commands via `docker compose exec laravel.test`
- **Pest tests:** Use `test()` closures, `RefreshDatabase` is auto-applied, use `expect()` chaining
- **PHP version:** Already upgraded to PHP 8.4 in compose.yaml
- **Test DB:** phpunit.xml configured for `DB_CONNECTION=sqlite`, `DB_DATABASE=:memory:`
- **Application will be non-functional** after Story 0.1 migration until this story is complete — Stories 0.1 + 0.2 should run in same session
- **FK constraint caution:** When dealing with foreign keys, use explicit column array syntax for cross-driver compatibility

### Warning: Frontend Will Break After This Story

After this story, the application frontend will be broken until Story 0.3 (frontend rename) is completed:
- Vue components still import from `@/pages/folders/`
- TypeScript types still reference `Folder`
- Wayfinder routes will regenerate with `declarations.*` names but frontend still uses old names
- **Stories 0.2 and 0.3 should be implemented in close succession**

### Testing Standards

- Use **Pest** syntax (`test()` closures), never PHPUnit class-based tests
- `RefreshDatabase` is auto-applied via `Pest.php` — don't add manually
- Run tests: `composer test`
- Feature tests grouped by domain: `tests/Feature/Declaration/`, `tests/Feature/Notification/`
- Use `route()` helper for URLs in tests
- After rename, run full test suite to catch any missed references

### Project Structure Notes

- All file renames should use `git mv` to preserve history
- New migration file goes in `database/migrations/` with timestamp `2026_03_11_000002`
- Test directory rename: `tests/Feature/Folder/` → `tests/Feature/Declaration/`
- Email templates: `resources/views/emails/folder-*.blade.php` → `declaration-*.blade.php`

### Debug Log References

N/A

### Completion Notes List

- All 40+ files renamed/updated successfully using `git mv` for history preservation
- Fixed pre-existing bug: `withValidator` `$this->merge()` in `after` callback doesn't affect `$request->validated()` — moved period field nullification to controller
- Fixed rollback test: updated `--step` from 1 to 2 to account for the new polymorphic migration
- Fixed pre-existing test failure (`ProfileUpdateTest > user can delete their account`) — `SoftDeletes` trait makes `fresh()` return soft-deleted record instead of null, changed assertion to `expect($user->fresh()->deleted_at)->not->toBeNull()`
- Frontend prop names (`createFolderUrl`, `assignedFolders`, `'folder'`, `'folders'`) intentionally kept unchanged — will be renamed in Story 0.3
- Inertia render paths (`'folders/Index'`, `'folders/Show'`, etc.) intentionally kept unchanged — frontend Vue files not yet renamed
- [AI-Review] Cosmetic changes applied outside story scope: EOF newline fixes (13 test files), import reordering (3 activity log migrations, User.php), whitespace formatting (2 workspace request files), unused import removal (ClientEmailTest.php). These do not affect functionality but represent undisciplined scope.
- [AI-Review] `activity_log.causer_type` verified safe — Spatie defaults to `App\Models\User` as causer, no custom `causedBy()` calls exist. No migration needed.
