+# Projektkonventionen
+
+## Architektur: Actions (Request-Command-Response)
+
+Jede fachliche Operation wird in eine eigene Action ausgelagert, die aus drei Klassen besteht.
+Pfad: `app/Domains/{Domain}/Actions/{ActionName}/`
+
+### Struktur
+{ActionName}Request.php → Eingabedaten (Konstruktor oder Factory-Methoden) {ActionName}Command.php → Logik, ruft execute(): {ActionName}Response auf {ActionName}Response.php → Rückgabedaten (public Properties)
+
+
+### Regeln
+- Der Controller enthält **keine** fachliche Logik – nur Absicherung, Action-Aufruf und HTTP-Response
+- Commands sind nicht statisch und werden immer instanziiert
+- Hat ein Request mehrere Varianten, werden **Factory-Methoden** (`forX()`) statt mehrerer Konstruktoren verwendet
+- Aufrufreihenfolge im Controller: `new Request → new Command(request) → command->execute() → Response verwenden`
+
+---
+
+## Controller
+
+- Alle Controller erben von `App\Scopes\CommonController`
+- `CommonController` stellt folgende Repositories bereit (keine eigene Instanziierung nötig):
+    - `$this->eventParticipants` → `EventParticipantRepository`
+    - `$this->events` → `EventRepository`
+    - `$this->invoices` → `InvoiceRepository`
+    - `$this->costUnits` → `CostUnitRepository`
+    - `$this->users` → `UserRepository`
+    - `$this->tenant` → aktueller `Tenant`
+
+---
+
+## Repositories
+
+- Datenbankzugriffe gehören **immer** ins Repository, nie direkt in Controller oder Actions
+- Sicherheitschecks (z. B. „gehört diese Teilnahme dem eingeloggten User?") werden als eigene Repository-Methoden gekapselt
+- Tenant-Filter: `app('tenant')->slug`
+- Eingeloggter User: `auth()->user()`
+
+---
+
+## Models / Ressourcen
+
+- Models erben von `App\Scopes\InstancedModel` (mit globalem `SiteScope`)
+- `$model->toResource()->toArray($request)` liefert das aufbereitete Array über die zugehörige Resource-Klasse
+- Resource-Klassen liegen in `app/Resources/{ModelName}Resource.php`
+
+---
+
+## Tenant
+
+- Der aktuelle Tenant ist per `app('tenant')` verfügbar (gesetzt durch `IdentifyTenant`-Middleware)
+- Tenant-Slug: `app('tenant')->slug`
+- Jede tenant-spezifische DB-Abfrage filtert auf `['tenant' => app('tenant')->slug]`
+
+---
+
+## Routing
+
+- API-Routen liegen in `app/Domains/{Domain}/Routes/api.php`
+- Alle Routen sind in `IdentifyTenant::class`-Middleware gewrappt
+- Authentifizierte Routen zusätzlich in `['auth']`-Middleware
+
+---
+
+## Mails
+
+- Mails erben von `Illuminate\Mail\Mailable`
+- Attachments werden über `Attachment::fromData(fn () => $content, $filename)->withMime(...)` angehängt
+- Werden Daten sowohl in `content()` als auch in `attachments()` benötigt, wird eine **private Hilfsmethode mit Lazy-Caching** verwendet (einmaliges Berechnen, Ergebnis in private Property speichern)
+- Blade-Templates referenzieren Mail-Attachments per `cid:`-Link: `<a href="cid:{{ $filename }}">...</a>`
