fix: use @example.com in test emails, .local rejected by email-validator

fix: pin bcrypt==3.2.2 for passlib 1.7.4 compatibility
fix: use sync setup_database + NullPool per test to avoid event loop issues

-## Offene Arbeit
+## Phase 1 – Status: ABGESCHLOSSEN ✓

- [ ] Techstack festlegen
- [ ] feature/grundstruktur → develop mergen (wenn Techstack entschieden)
+Alle Dateien implementiert und gepusht. System ist startbereit.

-## Zuletzt abgeschlossen
+## Offene Arbeit – nächste Session

- Repo-Infrastruktur aufgebaut (CLAUDE.md, Standards, Branching, README, PR-Template)
- .gitattributes, bump.sh, new-feature.sh, session-context.md eingeführt
- Branch Protection + Squash-Merge serverseitig konfiguriert
+Phase 1 ist fertig. Nächste Schritte nach Rücksprache mit Nutzer:
+
+1. **System testen** – `docker compose -f docker-compose.dev.yml up` ausführen und manuell prüfen
+2. **Ersten Superadmin anlegen** – Es gibt noch kein UI dafür, muss per DB-Insert oder API-Skript erfolgen
+3. **Phase 2 starten** – Testing & CI/CD (Gitea Actions, pytest, Vitest, Playwright)
+
+## Hinweis: Superadmin erstellen
+
+Noch kein UI vorhanden. Seed-Skript oder direkt per Python:
+```bash
+docker compose exec backend python3 -c "
+import asyncio
+from app.db.session import AsyncSessionLocal
+from app.models.user import User
+from app.core.security import get_password_hash
+import uuid
+
+async def create():
+    async with AsyncSessionLocal() as db:
+        user = User(id=uuid.uuid4(), email='admin@example.com',
+                    hashed_password=get_password_hash('changeme'),
+                    full_name='Superadmin', is_superadmin=True)
+        db.add(user)
+        await db.commit()

 This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

-## Projekt
+## Verhaltensregeln

-**Gartenmanager** – Anwendung zur Verwaltung von Gartenaktivitäten (Pflanzen, Beete, Aussaatkalender, Aufgaben, Bewässerung).
+- Kein erklärender Text bei Routineaufgaben (Commits, Pushes, Branch-Wechsel)
+- Bei Fehlern: erst 2x selbst versuchen, dann fragen
+- Branches selbstständig wechseln wie benötigt

-## Dokumente – wo was steht
+## Sprache & Konventionen

-| Dokument | Inhalt |
-|---|---|
-| [docs/development-standards.md](docs/development-standards.md) | **Alle Regeln:** Branching, Versionierung, Workflow, Coding, Testing |
-| [docs/project-structure.md](docs/project-structure.md) | **Alle Module & Funktionen** – hier zuerst lesen, bevor Quellcode geöffnet wird |
-| [docs/branching-strategy.md](docs/branching-strategy.md) | Branch-Diagramm |
-| [CHANGELOG.md](CHANGELOG.md) | Versionshistorie |
-| [VERSION](VERSION) | Aktuelle Versionsnummer |
-| [.claude/session-context.md](.claude/session-context.md) | **Sessionstart hier lesen:** aktiver Branch, Version, offene Arbeit |
-| [.claude/scripts/](.claude/scripts/) | Automatisierungsscripts (bump, new-feature) |
+- **Code-Bezeichner, Commit-Messages:** Englisch, Imperativ (`Add`, `Fix`, `Refactor`)
+- **Dokumentation & Kommentare:** Deutsch
+- **Commit-Format:** `<type>: <short description>` (max. 72 Zeichen)  
+  Types: `feat` | `fix` | `refactor` | `test` | `docs` | `chore`
+- Nach jedem Commit sofort pushen
+- Keine `console.log`/`print` in Produktionscode, keine auskommentierten Code-Blöcke

-## Techstack
+## Projektkontext (Schnelleinstieg)

-> Noch festzulegen – diese Sektion aktualisieren, sobald der Stack definiert ist.
+**Gartenmanager** – Docker-basierte Gartenverwaltung. Multi-User, Multi-Tenant, Rollensystem.  
+**Stack:** Vue 3 + PrimeVue → FastAPI (Python 3.11) → PostgreSQL 15  
+**Phase:** 1 abgeschlossen (Auth, Beete, Pflanzen, Bepflanzung). Phase 2 = Testing & CI/CD.  
+**Version:** `cat VERSION` | **Branch:** `git branch --show-current`  
+**Sessionstart:** [.claude/session-context.md](.claude/session-context.md) lesen.  
+**Modulreferenz:** [docs/project-structure.md](docs/project-structure.md) – vor Quellcode-Reads.

-## Build & Entwicklung
+## CI/CD Workflow

-> Befehle eintragen, sobald Build-System definiert ist.
+**Pflicht vor jedem Merge nach `develop`:**

 ```bash
-# Abhängigkeiten installieren
-# <install-command>
-
-# Entwicklungsserver starten
-# <dev-command>
-
-# Tests ausführen
-# <test-command>
-
-# Einzelnen Test ausführen
-# <single-test-command>
-
-# Linting
-# <lint-command>
-
-# Build für Produktion
-# <build-command>
-
-# Version bumpen + commit + push (patch/minor/major)
-bash .claude/scripts/bump.sh patch "Beschreibung der Änderung"
-
-# Neuen Feature-Branch erstellen
-bash .claude/scripts/new-feature.sh <name>
+# 1. Auf ci/staging mergen und pushen
+git checkout ci/staging
+git merge feature/<name>
+git push
+# 2. Warten bis alle Actions grün sind (.gitea/workflows/test.yml)
+# 3. Erst dann nach develop mergen
+```
+
+**Gitea Actions:**
+- `test.yml` – läuft auf `ci/**`, `develop`, PRs nach `develop`/`main`
+- `publish.yml` – baut + pusht Container bei Push nach `develop` und `main`
+- Registry: `tea.jr-family.de` | Images: `admin/gartenmanager-backend`, `admin/gartenmanager-frontend`
+- develop → Tag `:dev` | main → Tag `:latest` + Versionsnummer
+
+## Scripts (immer diese verwenden)
+
+```bash
+bash .claude/scripts/git-commit.sh "message"              # stage all + commit + push
+bash .claude/scripts/git-switch.sh <branch>               # branch wechseln
+bash .claude/scripts/git-switch.sh <branch> from <base>   # neuer branch aus base
+bash .claude/scripts/git-pr.sh create <head> <base> "titel"  # PR erstellen
+bash .claude/scripts/git-pr.sh merge <nr> squash          # PR mergen
+bash .claude/scripts/git-pr.sh list                       # offene PRs
+bash .claude/scripts/bump.sh [patch|minor] "beschreibung" # version + commit + push

+**Tenant-Kontext:** Header `X-Tenant-ID` bei allen Nicht-Auth-Requests.  
+**Rollen:** `READ_ONLY` < `READ_WRITE` < `TENANT_ADMIN` < `is_superadmin`
+
+## Pflichtregeln
+
+1. **Nie direkt nach `main`** – nur PR, nur auf Anweisung
+2. **Arbeit in `feature/`, `fix/` oder `chore/`** unter `develop`
+3. **Nach jeder Änderung:** `bump.sh` ausführen (MINOR bei Features, PATCH bei Fixes)
+4. **MAJOR-Version** niemals selbstständig erhöhen
+5. **Vor Merge/PR:** CHANGELOG, README, `docs/project-structure.md` prüfen
+6. **In `develop` mergen erst** wenn alle Tests grün sind
+
+## Testing
+
+- Integrationstests testen gegen echte DB (keine DB-Mocks)
+- Backend: pytest in `backend/tests/` | Frontend: Vitest neben Quelldateien oder `__tests__/`
+- Run: `docker compose exec backend pytest` / `cd frontend && npm run test`
+
+## Build
+
+```bash
+docker compose -f docker-compose.dev.yml up   # Dev (hot-reload)
+docker compose up -d                           # Prod
+docker compose exec backend alembic upgrade head
+docker compose exec backend python -m app.seeds.initial_data
+cd frontend && npm run dev

+```
+is_superadmin=True  → alles erlaubt, Tenant-Prüfung wird übersprungen
+TENANT_ADMIN        → alles im eigenen Tenant (inkl. Beet löschen)
+READ_WRITE          → lesen + schreiben, kein Beet löschen
+READ_ONLY           → nur GET-Endpoints

+
+`require_min_role(TenantRole.READ_WRITE)` in `deps.py` gibt `(user, tenant_id, role)` zurück.

-> **Format pro Funktion:**
-> `funktionsname(param: Typ): Rückgabetyp` – Ein-Satz-Beschreibung

+plant_compat.   → plant_id_a, plant_id_b, rating, reason

-| Entität | Felder (geplant) | Beziehungen |
-|---|---|---|
-| `Plant` | name, sowingStart, sowingEnd, waterInterval, spacing | gehört zu Bed |
-| `Bed` | name, width, length, location | enthält viele Plants |
-| `SowingCalendar` | year, plantId, sowDate, plantDate | referenziert Plant |
-| `Task` | title, dueDate, done, bedId? | optional zu Bed |
-| `WateringSchedule` | bedId/plantId, intervalDays, lastWatered | referenziert Bed oder Plant |
