## Wichtige Befehle

```bash
# Entwicklung
pnpm dev
pnpm build

# Migrationen
pnpm payload migrate:create
pnpm payload migrate

# Schema-Sync (wichtig nach Collection-Änderungen!)
./scripts/sync-schema.sh --dry-run   # Zeigt Änderungen
./scripts/sync-schema.sh             # Führt Sync aus

# ImportMap nach Plugin-Änderungen
pnpm payload generate:importmap

# PM2
pm2 status | pm2 logs payload | pm2 restart payload
pm2 logs queue-worker | pm2 restart queue-worker

# Tests
pnpm test                  # Alle Tests
pnpm test:security         # Security Tests
pnpm test:access-control   # Access Control Tests
pnpm test:coverage         # Mit Coverage-Report

# Lint & Format
pnpm lint                  # ESLint
pnpm typecheck             # TypeScript Check (4GB heap)
pnpm format:check          # Prettier Check
pnpm format                # Prettier Auto-Fix

# Direkte DB-Verbindung (umgeht PgBouncer für Migrationen)
./scripts/db-direct.sh migrate
./scripts/db-direct.sh psql

# Backup
/home/payload/backups/postgres/backup-db.sh --verbose
```

## Git Workflow

**Regel:** Immer auf `develop` entwickeln, nach Freigabe nach `main` mergen.

| Branch | Zweck | Deployment |
|--------|-------|------------|
| `develop` | Aktive Entwicklung | Staging (pl.porwoll.tech) |
| `main` | Stabile Version | Production (cms.c2sgmbh.de) |
| `feature/*` | Feature-Branches | PR nach develop |

**Commit-Konventionen:** `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`

**Workflow nach Code-Änderungen:**
1. Code ändern (auf `develop`)
2. `pnpm build` → `pm2 restart payload`
3. Bei Collection-Änderungen zusätzlich: `pnpm payload migrate:create`

## KRITISCH: Neue Collections hinzufügen

Payload CMS verwendet `payload_locked_documents_rels` für Document-Locks. Diese Tabelle benötigt eine `{collection}_id` Spalte für JEDE Collection. Ohne → RSC-Fehler nach Login:

```
column payload_locked_documents_rels.{collection}_id does not exist
```

**Migration MUSS enthalten:**
```sql
ALTER TABLE "payload_locked_documents_rels"
  ADD COLUMN IF NOT EXISTS "{collection}_id" integer
  REFERENCES {collection}(id) ON DELETE CASCADE;

CREATE INDEX IF NOT EXISTS "payload_locked_documents_rels_{collection}_idx"
  ON "payload_locked_documents_rels" ("{collection}_id");
```

Beispiel: `src/migrations/20260109_020000_add_blogwoman_collections.ts`

**Array-Felder:** Collections mit Arrays benötigen zusätzliche `{collection}_{array_field}` Tabellen.

## Bekannte Besonderheiten & Gotchas

- **ES Modules:** `"type": "module"` in package.json → PM2 Config als `.cjs`
- **Plugin ImportMap:** Nach Plugin-Änderungen `pnpm payload generate:importmap`
- **User-Tenant-Zuweisung:** Neue User müssen manuell Tenants zugewiesen bekommen
- **Admin Login:** Custom Route mit Audit-Logging (`src/app/(payload)/api/users/login/route.ts`)
- **Queue Worker:** PM2 nutzt `node_modules/tsx/dist/cli.mjs` direkt (nicht `npx`), `exec_mode: 'fork'`
- **PgBouncer:** Transaction-Mode kann Migrationen stören → `./scripts/db-direct.sh`
- **Tenant SMTP Save (Stand 17.02.2026):** Bei conditional `email.smtp` keine Feld-`required` auf `host/user`; stattdessen Group-`validate` verwenden. Tenant-Audit-Hook darf Admin-Save nicht mit `await` blockieren.
- **TRUST_PROXY=true:** PFLICHT hinter Reverse-Proxy, sonst funktionieren Rate-Limiting und IP-Allowlists nicht
- **CSRF_SECRET:** PFLICHT in Production (oder PAYLOAD_SECRET) - Server startet nicht ohne

## Build-Konfiguration

- `package.json`: `--max-old-space-size=2048` (2GB Heap-Limit)
- `next.config.mjs`: `experimental.cpus: 1`, `workerThreads: false`

**Server hat 8GB RAM ohne Swap.** Bei laufendem VS Code kann Build OOM werden:
```bash
pm2 stop payload
NODE_OPTIONS="--no-deprecation --max-old-space-size=1024" ./node_modules/.bin/next build
pm2 start payload
```

## Security Kurzübersicht

- **Rate-Limiting:** publicApi(60/min), auth(5/15min), email(10/min), search(30/min), form(5/10min)
- **CSRF:** Double Submit Cookie + Origin-Validierung, Token: `GET /api/csrf-token`
- **IP-Allowlist:** `SEND_EMAIL_ALLOWED_IPS`, `ADMIN_ALLOWED_IPS`, `BLOCKED_IPS` (IPs, CIDRs, Wildcards)
- **Data-Masking:** Automatisch in Logs (Passwörter, Tokens, API-Keys)
