- Add doctrine/doctrine-fixtures-bundle (^4.3) for database fixtures
- Add phpstan/phpstan (^2.0) as dev dependency for static analysis
- Register DoctrineFixturesBundle in dev/test environments
- Move entity mapping to src/Data/Doctrine/Entity/Saatgut
- Update entity prefix to App\Data\Doctrine\Entity\Saatgut
- Change entity alias from App to Saatgut

+# PHP & Symfony Engineering Guidelines
+
+## 1. Core PHP Standard
+Wir schreiben modernen, typensicheren und expliziten Code. Ziel ist es, Fehler zur Compile-Zeit bzw. via statischer Analyse zu finden.
+
+*   **Strict Typing:** Jede Datei beginnt zwingend mit `declare(strict_types=1);`.
+*   **Typisierung:** 
+    *   Konsequentes Type Hinting für alle Parameter und Rückgabewerte (inkl. `void`).
+    *   Nutzung von Union- und Intersection Types.
+    *   `mixed` ist verboten, außer in absolut unvermeidbaren Generics.
+*   **Modern Features (PHP 8.2+):**
+    *   **Readonly:** Standard für DTOs, Value Objects und Services (`readonly class`).
+    *   **Constructor Promotion:** Nutzung zur Reduktion von Boilerplate.
+    *   **Enums:** Einsatz anstelle von Konstanten oder Strings für feste Zustände.
+    *   **Match Expression:** Bevorzugt gegenüber `switch`.
+*   **Anti-Magic:** Magic Methods (`__call`, `__get` etc.) und dynamische Properties sind **strikt verboten**.
+
+## 2. Control Flow & Readability
+Lesbarkeit schlägt akademische Perfektion. Code muss für andere Senioren ohne "Rätselraten" sofort verstehbar sein.
+
+*   **Control Flow:** Nutzung von **Early Returns** und **Guard Clauses**. Verschachtelte `if-else`-Strukturen sind zu vermeiden, um die kognitive Last gering zu halten.
+*   **Self-Explaining Code:** Namen müssen den Intent beschreiben (`calculateTotalTax()` statt `calc()`). Booleans beginnen mit `is`, `has` oder `can`.
+*   **Kommentare:** Kommentare werden nur eingesetzt, wenn:
+    1.  Der Code aufgrund einer Sonderlösung **nicht selbsterklärend** ist (Dokumentation des "Warum").
+    2.  **Arrays/Collections typisiert** werden müssen (`/** @var UserDTO[] $users */`), sofern PHPStan dies nicht anders erfassen kann.
+
+## 3. Data Structures & Collections
+Wir vermeiden "Mystery Meat"-Datenstrukturen zugunsten von Typsicherheit.
+
+*   **No Associative Arrays:** Die Nutzung von assoziativen Arrays als Pseudo-Objekte/Datencontainer ist verboten. Es werden immer **dedizierte Objekte (DTOs)** verwendet.
+*   **Collections:** 
+    *   **Transport:** Für einfache Listen, die nur durchiteriert werden, reichen typisierte Arrays (`array<T>`).
+    *   **Domain-Logik:** Sobald eine Liste fachliche Logik besitzt (z.B. Filterung, Aggregation), wird eine dedizierte **Collection-Klasse** erstellt (implementiert `IteratorAggregate` und `Countable`).
+
+## 4. Infrastructure & Symfony Implementation
+Symfony ist der Adapter zur Außenwelt, nicht das Zentrum der Applikation.
+
+*   **Dependency Injection:** Ausschließlich **Constructor Injection**. Kein Service-Locator (`$this->container->get()`). DI erfolgt primär gegen Interfaces (Ports).
+*   **Controller:** "Thin Controller". Aufgaben sind: Request-Daten validieren/extrahieren $\rightarrow$ Application-Service aufrufen $\rightarrow$ Response transformieren. Keine Business-Logik im Controller.
+*   **Third-Party SDKs:** Alle externen Services/SDKs werden konsequent hinter einem **eigenen Interface (Port)** in der Infrastructure-Schicht gekapselt. Vendor-Klassen dürfen niemals den Application- oder Domain-Layer erreichen.
+
+## 5. Persistence & Entity Design
+Wir minimieren die Koppelung an das ORM, um Performance und Testbarkeit zu sichern.
+
+*   **Simple Entities:** Entitäten werden flach gehalten.
+*   **Avoid Joins:** Gejointe Entitäten (komplexe `@ManyToOne` / `@OneToMany`) sind grundsätzlich zu vermeiden. Referenzen erfolgen über **IDs**. Die Zusammenführung erfolgt explizit in den Repositories/Services.
+*   **Mapping:** Transformationen zwischen Infrastructure-Entities und Domain-Modellen erfolgen ausschließlich über dedizierte **Mapper-Klassen in der Dataschicht**.
+
+## 6. Validation Pipeline (Shift-Left)
+Fehler werden so früh wie möglich abgefangen:
+`Request` $\rightarrow$ `DTO Asserts/Validation` $\rightarrow$ `Application Logic` $\rightarrow$ `Domain Complex Tests`.
+
+## 7. Quality Gates & Workflow (Definition of Done)
+Bevor Code in ein Review geht, müssen folgende lokale Checks erfolgreich durchlaufen sein:
+
+1.  **Syntax Check:** `php -l`
+2.  **Statische Analyse:** `phpstan analyse` (Ziel Level 8/9). *Pragmatismus-Regel:* Wenn Typisierung die Lesbarkeit massiv zerstört $\rightarrow$ Review-Dialog statt "Force-Typing".
+3.  **Automatisierte Tests:** `phpunit` (Unit, Integration, Functional).
+
+---
+
+### Die Golden Rules im Überblick:
+1. **Kein Framework / Keine Vendor-Klassen im Domain.**
+2. **Flache Entitäten / Referenzen über IDs.**
+3. **Immutability by Default (`readonly`).**
+4. **Keine assoziativen Arrays $\rightarrow$ Dedizierte Objekte.**
+5. **Early Returns $\rightarrow$ Flacher Code.**
+6. **Local Check: `php -l` $\rightarrow$ `phpstan` $\rightarrow$ `phpunit`.**

+# 🌿 GardenPlan – Gartenplanung MVP
+
+> Symfony-Basises für die Multi-Garten-Planung mit Pflanzen, Aussaat, Ernte & Aufgaben.
+
+## 🏗️ Architektur
+
+Strikte Schichtenarchitektur (Clean / Hexagonal):
+**UI** → **Logic** → **Data**
+
+Details: [Architektur-Dokumentation](Doku/architektur.md)
+
+## 📋 Anforderungsprofil
+
+[Hier ansehen](Doku/anforderungsprofil.md)
+
+---
+
+## 🚀 Schnellstart
+
+### 1. DockerCompose-Setup starten
+
+```bash
+docker compose up -d
+```
+
+Startet folgende Services:
+| Service | Port | Beschreibung |
+|---------|------|--------------
+| **nginx** | `80` / `443` | Webserver für Symfony REST-API
+| **php-fpm** | (intern) | PHP 8.3 + Symfony Runtime
+| **PostgreSQL** | `5432` | Datenbank (`gardenplan` + `keycloak_db`)
+| **Keycloak** | `8080` | OIDC/JWT Identity Provider
+
+### 🔑 Zugangsdaten (Dev)
+
+| System | Benutzer | Passwort | URL |
+|--------|----------|----------|-----|
+| **Database** | `symfony` | `changeme` | `postgresql://database:5432/gardenplan` |
+| **Keycloak Admin** | `admin` | `adminsecret` | http://localhost:8080 |
+| **Test-Nutzer** | `testuser` | `testpassword123!` | (in Keycloak Realm `gardenplan`)
+
+### 📦 Nach dem ersten Start
+
+```bash
+# In den PHP-Container wechseln
+docker compose exec php-fpm bash
+
+# Symfony Projekt setup
+cd /var/www/html
+composer install
+
+# Datenbankmigrationen ausführen
+php bin/console doctrine:database:create
+php bin/console doctrine:migrations:migrate --no-interaction
+
+# JWT-Schlüssel für Lexik Bundle generieren
+php bin/console lexik:jwt:generate-keypair
+```
+
+---
+
+## 📐 Ordnerstruktur
+
+```
+src/
+├── UI/                  # Controller, Commands, MessageHandlers
+├── Logic/               # UseCases, Manager, Domain Services
+│   ├── Domain/          # Models, DTOs, Validators, Policies
+│   └── InfrastructureInterface/  # Provider / Processor Interfaces
+└── Data/                # Doctrine Entities, Mappers, Implementations
+```
+
+---
+
+## 📖 Aufgabenplan
+
+| Task | Beschreibung | Status |
+|------|-------------|--------|
+| [01 – Infrastruktur](Doku/Tasks/01-Infra.md) | Docker, DB, Keycloak Setup | ✅ In Arbeit |
+| 02 – Datenbank-Schema | Entities + Migrationen | ⏳ Offen |
+| 03 – Planning-Domain | GardenPlan Model, UseCases | ⏳ Offen |
+| 04 – REST API | Controller + DTOs | ⏳ Offen |
+| 05 – Auth & RBAC Keycloak Integration | ⏳ Offen |
+
+---
+
+## 🔧 Entwicklung
+
+```bash
+# Logs einsehen
+docker compose logs -f php-fpm
+docker compose logs -f nginx
+
+# Container neu starten
+docker compose restart php-fpm
+
+# Alles stoppen
+docker compose down
+```
+
+## .env-Variabeln kopieren & anpassen. Siehe `.env`.
+

+
+**🌱 Happy Gardening!**
