+| Repo | Path | Branch | Purpose |
+|------|------|--------|---------|
+| **cts-work** | `/Users/thorsten/AI/cts-work` | `cts-presenter-app` | Laravel app (main codebase) |
+| **propresenter-work** | `/Users/thorsten/AI/propresenter-work/php` | `propresenter-parser` | ProPresenter .pro/.proplaylist parser (composer path dependency) |

+## Code Style -- PHP
 
 - **Formatter**: Laravel Pint (default Laravel preset, no custom config)
-- **Indentation**: 4 spaces
-- **Imports**: Fully qualified, one per line, grouped (PHP classes, then Laravel, then app)
-- **Models**: Use `$fillable` array (not `$guarded`). Use `casts()` method (not `$casts` property). Relationships return typed `HasMany`/`BelongsTo`/etc.
-- **Controllers**: Return type hints (`Response`, `JsonResponse`, `RedirectResponse`). Use route-model binding. Use `Inertia::render()` for page responses.
-- **Migrations**: Anonymous class style: `return new class () extends Migration { ... }`
-- **Error messages**: German. Flash via `->with('success', '...')`. JSON errors use `message` key.
-- **Null safety**: Use nullsafe operator `?->` and null coalescing `??`
-- **DB operations**: Prefer Eloquent, fall back to `DB::table()` for bulk upserts in sync code
-- **SoftDeletes**: Used on `Song` model. Use `whereNull('deleted_at')` in manual queries.
+- **Imports**: Fully qualified, one per line, alphabetical. App\ first, then Illuminate\, then external.
+- **Constructors**: Promoted properties with `private readonly`. Empty body: `{}` on same line.
+  ```php
+  public function __construct(
+      private readonly SongMatchingService $songMatchingService,
+  ) {}
+  ```
+- **Return types**: Always present. Use union types for multiple returns: `Response|JsonResponse`.
+- **String concat**: No spaces around `.` operator: `'Fehler: '.$e->getMessage()`
+- **Null safety**: Nullsafe `?->` and null coalescing `??`. Never suppress with `@`.
+- **Models**: `$fillable` array (never `$guarded`). `casts()` method (never `$casts` property). Typed relationship returns (`HasMany`, `BelongsTo`). `Attribute::get()` for computed accessors.
+- **Migrations**: Anonymous class: `return new class extends Migration {`. Methods: `up(): void`, `down(): void`.
+- **Error messages**: German, Du-form. Flash: `->with('success', '...')`. JSON: `'message'` key.
+- **Validation**: Inline `$request->validate([...])` with `Rule::in()` for enums.
+- **Transactions**: `DB::transaction(function () use (...): void { ... })` for multi-step writes.
+- **Constants**: `private const NAME = [...]` for fixed value sets.
 
-## Code Style — Vue / Frontend
+## Code Style -- Vue / Frontend
 
-- **Vue 3 Composition API** only, always `<script setup>`. No Options API.
-- **Props**: `defineProps({ propName: { type: Type, default: value } })`
-- **Emits**: `defineEmits(['event-name'])`
-- **Imports**: Use `@/` alias for `resources/js/`. Vue imports from `'vue'`, Inertia from `'@inertiajs/vue3'`.
-- **Functions**: Prefer `function name() {}` declarations in components (not `const name = () => {}`)
-- **Styling**: Tailwind CSS v4 utility classes inline. Scoped `<style>` only when necessary (e.g. drag-and-drop).
-- **State**: `ref()` for reactive state, `computed()` for derived. Use `watch()` for side effects.
-- **Routing**: Use `route('name', params)` (Ziggy) for URL generation. Use `router.post/get/delete` from Inertia.
-- **Testing attributes**: Add `data-testid="..."` on interactive elements for Playwright e2e tests.
-- **All user-facing text must be German** (Du-form, not Sie).

-## Code Style — Tests
+## Code Style -- Tests
 
-- **Framework**: Pest v4 (wraps PHPUnit). Feature tests are class-based extending `TestCase` with `RefreshDatabase`.
-- **Naming**: `test_snake_case_german_description` (e.g. `test_service_kann_abgeschlossen_werden`)
+### PHP Tests (Pest v4 + PHPUnit)
+
+Both styles are used:
+- **Function-based Pest**: `test('snake_case german description', function () { ... });` with `beforeEach`
+- **Class-based**: `final class NameTest extends TestCase { use RefreshDatabase; public function test_snake_case(): void {} }`
 - **Auth**: `$this->actingAs(User::factory()->create())`
-- **Vite**: Call `$this->withoutVite()` before testing Inertia page renders
-- **Time**: Use `Carbon::setTestNow('2026-03-01 10:00:00')` for deterministic time
-- **Assertions**: `assertInertia(fn ($page) => $page->component('...')->has('...')->where('...'))` for Inertia responses
-- **DB**: Tests use in-memory SQLite (configured in `phpunit.xml`)
-- **e2e**: Playwright (TypeScript), `tests/e2e/`, baseURL `http://cts-work.test`, auth via `auth.setup.ts`
+- **Vite**: Call `$this->withoutVite()` before Inertia page render tests
+- **Time**: `Carbon::setTestNow('2026-03-01 10:00:00')` for deterministic dates
+- **Inertia assertions**: `$response->assertInertia(fn ($page) => $page->component('...')->has('...')->where('...'))`
+- **DB**: In-memory SQLite (`phpunit.xml`: `DB_CONNECTION=sqlite`, `DB_DATABASE=:memory:`)
+- **Helper functions**: Define at file level for shared test setup (e.g. `function makePngUpload(...)`)
+- **Storage**: `Storage::fake('public')` in `beforeEach` for file upload tests
 
-## Key Conventions
+### ProPresenter Parser Tests (PHPUnit 11)
 
-- **CTS API is READ-ONLY** — never write/modify data via ChurchTools API
-- **Immediate persistence** — all user actions save instantly, no separate "save" button
-- **German locale** — `APP_LOCALE=de`, all UI text in German, Du-form
-- **File uploads** — images convert to JPG 1920x1080 (maintain aspect ratio, no cropping); PPT/PPTX convert to multiple JPGs
-- **Named routes** — all routes have names, use `route('name')` everywhere
-- **ProPresenter (.pro) parser** — placeholder only, not yet implemented
+- Uses `#[Test]` attribute (not `test_` prefix)
+- `setUp()`/`tearDown()` for temp directory management
+- Fixtures in `ref/` directory, loaded via `dirname(__DIR__, 2).'/ref/...'`
+- Strict mode: `failOnRisky`, `failOnWarning`, `beStrictAboutOutputDuringTests`
+
+### E2E Tests (Playwright)
+
+- TypeScript in `tests/e2e/`, baseURL `http://cts-work.test`
+- Auth via `auth.setup.ts` (XSRF token + `/dev-login` endpoint, saves state to `.auth/user.json`)
+- Selectors: `page.getByTestId('...')`, `page.getByText('...')`, `page.getByRole('...')`
+- German text assertions: `await expect(page.getByText('Mit ChurchTools anmelden')).toBeVisible()`
+
+## Key Constraints
+
+- **CTS API is READ-ONLY** -- never write/modify data via ChurchTools API
+- **Immediate persistence** -- all user actions save instantly (no separate save button)
+- **German locale** -- `APP_LOCALE=de`, all UI text German Du-form
+- **File uploads** -- images convert to JPG 1920x1080 (maintain aspect, no crop); PPT/PPTX to multiple JPGs
+- **Named routes** -- all routes have names, use `route('name')` everywhere
+- **No type suppression** -- never use `as any`, `@ts-ignore`, `@ts-expect-error` in frontend
+- **SoftDeletes** -- used on Song and Slide models; use `whereNull('deleted_at')` in manual queries
