+# 🤖 JARVIS - Übergabe Dokumentation
+
+**Projekt:** JARVIS KI-Assistent + Business Automation
+**Erstes Deployment:** 12.09.2026
+**Status:** ✅ Live auf VPS 72.61.186.98 (Postgres, Redis, Ollama, n8n, JARVIS-API, JARVIS-Web)
+**Owner:** Jonny (MBO-Tech-IT)
+
+---
+
+## 📋 Übersicht
+
+JARVIS ist ein **vollständig selbst gehosteter AI-Assistant + Business Automation Stack** auf einem VPS mit Docker-Orchestrierung. Chat-Zugriff läuft über eine eigene Web-Oberfläche (React) und spricht über Claude Tool Use direkt mit Kalender und E-Mail-Postfach.
+
+**Kernkomponenten:**
+- 🤖 **KI-Backend**: Claude API (Chat + Tool Use) + Ollama (lokale Embeddings)
+- 💾 **Datenbank**: PostgreSQL mit `pgvector`-Extension (strukturierte Daten + Vector Search in einer DB, kein separates Milvus)
+- ⚡ **Cache**: Redis (aktuell nur fürs Health-Check vorbereitet, noch nicht aktiv genutzt)
+- 🔄 **Automation**: n8n (Workflow Engine) - Wetter- und E-Mail-Cache laufen bereits darüber
+- 📡 **API**: FastAPI (Python Backend, `main.py`)
+- 🌐 **Web-Frontend**: React/Vite, nginx-served
+- 🔌 **Externe Integrationen**: Nextcloud-Kalender (CalDAV), E-Mail-Postfach (IMAP/SMTP)
+- 🌐 **Reverse Proxy**: bereits vorhandener, JARVIS-fremder Traefik auf dem VPS (siehe unten)
+- 🐳 **Container**: 6 Docker-Container (siehe "Docker Container Status")
+
+---
+
+## 🔑 Zugriffsdaten
+
+```
+VPS IP:        72.61.186.98
+User:          jarvis-core
+SSH Key:       ~/.ssh/jarvis_core_key
+Domain:        jarvis.mbo-tech-it.de
+Location:      /home/jarvis-core/jarvis
+```
+
+### SSH-Zugriff
+```bash
+ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98
+```
+Die Flags `-F /dev/null -o IdentitiesOnly=yes` sind nötig, damit die globale
+lokale `~/.ssh/config` nicht in die Schlüsselauswahl reinpfuscht.
+
+**Wichtig:** `jarvis-core` muss in `/etc/ssh/sshd_config` unter `AllowUsers` stehen, sonst wird jeder Key mit "Permission denied" abgelehnt, obwohl der Key korrekt ist (passiert am 12.09.2026, gefixt durch Ergaenzen von `jarvis-core` in der `AllowUsers`-Zeile + `systemctl reload ssh`).
+
+### n8n-Zugriff
+```
+URL:   https://n8n.jarvis.mbo-tech-it.de
+User:  jonny@mbo-tech-it.de (Owner-Account, Passwort nicht in dieser Doku)
+```
+API-Keys fuer die n8n-REST-API werden unter Settings -> n8n API verwaltet
+(pro Key eigenes Ablaufdatum). Aktuell existieren: "JARVIS Weather Workflow"
+(Ablauf 12.10.2026) und "JARVIS Email Workflow Runtime" (Ablauf 13.10.2026,
+fuer den E-Mail-Cache-Workflow angelegt). Die Key-Werte selbst sind nirgends
+dauerhaft gespeichert (nur beim Erstellen einmalig sichtbar) - bei Bedarf
+einfach einen neuen erstellen.
+
+### Database Credentials
+```
+PostgreSQL User:     jarvis
+PostgreSQL Database: jarvis (n8n hat eine eigene DB "n8n" in derselben Instanz)
+PostgreSQL Port:     5432
+Password:            in .env (DB_PASSWORD)
+```
+
+### Externe Dienste (Zugangsdaten in `.env` auf dem VPS)
+- **Nextcloud-Kalender** (`NEXTCLOUD_CALDAV_URL`, `NEXTCLOUD_USER`, `NEXTCLOUD_APP_PASSWORD`): `https://cloud.ffw-onza.de/.../ffw-onza-alle/`, App-Passwort-Auth
+- **E-Mail-Postfach** (`EMAIL_USER`, `EMAIL_PASSWORD`, `EMAIL_IMAP_HOST/PORT`, `EMAIL_SMTP_HOST/PORT`): `kontakt@mbo-tech-it.de` auf `mx2f35.netcup.net` (IMAP 143 STARTTLS, SMTP 465 implizites TLS)
+- **Claude API** (`CLAUDE_API_KEY`): console.anthropic.com, separat vom Claude-Pro-Abo

+## 📍 Services & Ports
+
+| Service | URL | Port | Status | Notes |
+|---------|-----|------|--------|-------|
+| **Web-Frontend** | https://jarvis.mbo-tech-it.de | 80 (intern, nginx) | 🟢 Live | Chat + Dashboard, Shared-Secret-Login mit `API_KEY_ADMIN` |
+| **API** | https://api.jarvis.mbo-tech-it.de | 8000 (intern) | 🟢 Live | FastAPI Swagger UI: `/docs`. Alle `/api/v1/*` Routen ausser `/health` brauchen Header `X-Admin-Key` |
+| **n8n** | https://n8n.jarvis.mbo-tech-it.de | 5678 (intern) | 🟢 Live | Workflow Automation - 2 aktive Workflows (Wetter, E-Mail-Cache) |
+| **Traefik** | - | 80/443 | 🟢 Genutzt (fremd) | Server hat bereits einen eigenen Traefik fuer andere Projekte. JARVIS-eigener Traefik-Service wurde entfernt (Port-Konflikt), stattdessen haengt JARVIS per Labels + externem Netzwerk `proxy-network` am bestehenden Traefik. TLS ueber Let's-Encrypt-Resolver `netcup` (DNS-01) |
+| **PostgreSQL** | localhost | 5432 | 🟢 Live | Hauptdatenbank + Vector Search, Image `pgvector/pgvector:pg16` |
+| **Redis** | localhost | 6379 | 🟢 Live | Läuft und wird im Health-Check geprüft, im Code aber noch nicht aktiv fürs Caching genutzt |
+| **Ollama** | http://72.61.186.98:11434 | 11434 | 🟢 Live | Local LLM Runtime, genutzt für Embeddings (`nomic-embed-text` gepullt) |
+| **Milvus** | - | - | ⛔ Nie deployt | Ersetzt durch `pgvector` direkt in Postgres (siehe Phase 3a). Platzhalter-Services `milvus`/`etcd` stehen noch in `docker-compose.yml`, laufen aber nicht |
+
+**Traefik-Integration (12.09.2026):** JARVIS ist am bestehenden VPS-weiten Traefik
+(`docker-compose.yml` Projekt `traefik`, `/data/docker/compose/traefik/`) angehaengt:
+externes Docker-Netzwerk `proxy-network`, Labels an `jarvis-api`, `jarvis-web` und `n8n`
+(`traefik.docker.network=proxy-network`, `entrypoints=websecure`,
+`tls.certresolver=netcup`). DNS (`jarvis` A-Record + `*.jarvis` Wildcard) liegt
+bei Netcup. Falls eine neue Subdomain (z.B. `foo.jarvis.mbo-tech-it.de`) mal
+nicht auflöst, obwohl der Wildcard existiert: pruefen, ob ein expliziter
+(auch leerer) Eintrag exakt fuer diesen Namen existiert - der blockiert laut
+DNS-Wildcard-Regeln (RFC 1034) die Wildcard-Aufloesung nur fuer diesen einen
+Namen. **Beobachtet (12.09.2026):** Auch ohne sichtbaren blockierenden
+Eintrag im Netcup-Panel kann die Aufloesung eines frisch fuer eine
+DNS-01-Challenge verwendeten Namens (z.B. `api.jarvis...`) deutlich laenger
+brauchen als ein unberuehrter Wildcard-Name (bis zu ~20 Minuten beobachtet,
+vermutlich Netcup-interner Nebeneffekt der ACME-TXT-Record-Erstellung) -
+einfach abwarten, es loest sich von selbst.

+`milvus`/`etcd` stehen zwar noch als Service-Definitionen in
+`docker-compose.yml` (Platzhalter, nie funktionsfähig konfiguriert), werden
+aber mit `docker compose up -d` normalerweise nicht mit hochgezogen, wenn man
+gezielt einzelne Services neu startet (`docker compose up -d jarvis-api` etc.,
+so wie es in diesem Projekt durchgängig gemacht wird statt einem globalen
+`up -d`).

+
+---
+
+## 🔧 Wichtige Befehle
+
+**Hinweis:** Die installierte Docker-Compose-Version ist v2 (Plugin-Syntax
+`docker compose`, ohne Bindestrich) - das alte `docker-compose` (mit
+Bindestrich) ist auf dem VPS nicht garantiert vorhanden.
+
+### Container Management
+```bash
+cd /home/jarvis-core/jarvis
+
+# Alle starten
+docker compose up -d
+
+# Alle stoppen
+docker compose down
+
+# Logs anschauen
+docker compose logs -f
+
+# Spezifischen Service neustarten (Backend-Codeänderung reicht ein restart,
+# da main.py per Volume gemountet ist und uvicorn mit --reload läuft)
+docker compose restart jarvis-api
+
+# Frontend-Änderung braucht einen echten Rebuild (Multi-Stage-Dockerfile)
+docker compose build jarvis-web && docker compose up -d jarvis-web
+
+# In Container gehen
+docker compose exec jarvis-api bash
+docker compose exec postgres bash
+```
+
+### Database Management
+```bash
+# PostgreSQL CLI öffnen
+docker exec -it jarvis-postgres psql -U jarvis -d jarvis
+
+# Query ausführen
+docker exec jarvis-postgres psql -U jarvis -d jarvis -c "SELECT * FROM users;"
+
+# Migration anwenden (nach scp der .sql-Datei nach migrations/)
+docker exec -i jarvis-postgres psql -U jarvis -d jarvis < migrations/00X_name.sql
+
+# Backup erstellen
+docker exec jarvis-postgres pg_dump -U jarvis jarvis > jarvis_backup.sql
+
+# Backup wiederherstellen
+docker exec -i jarvis-postgres psql -U jarvis jarvis < jarvis_backup.sql
+```
+
+### API Testing
+```bash
+# Health Check (kein Header noetig)
+curl http://localhost:8000/health
+
+# Admin Stats (Header noetig)
+curl -H "X-Admin-Key: $API_KEY_ADMIN" http://localhost:8000/api/v1/admin/stats
+
+# Swagger UI im Browser
+https://api.jarvis.mbo-tech-it.de/docs
+```
+
+### Backend-Tests lokal ausführen (vor jedem Deploy)
+Lokales Python (3.14) kann `psycopg2-binary` nicht bauen (kein Wheel) - Tests
+laufen deshalb in einem `python:3.11-slim`-Container per SSH:
+```bash
+scp -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key \
+  "Claude outputs/main.py" "Claude outputs/requirements.txt" \
+  "Claude outputs/requirements-dev.txt" "Claude outputs/pytest.ini" \
+  jarvis-core@72.61.186.98:/tmp/jarvis-test/
+scp -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key \
+  "Claude outputs/tests/"*.py jarvis-core@72.61.186.98:/tmp/jarvis-test/tests/
+ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98 \
+  "docker run --rm -v /tmp/jarvis-test:/app -w /app python:3.11-slim bash -c \
+   'pip install -q -r requirements-dev.txt -r requirements.txt && python -m pytest tests/ -v'"
+```
+
+---
+
+## ⚙️ Konfiguration (.env, auf dem VPS unter `/home/jarvis-core/jarvis/.env`)

+
+## 🔌 Datenbankschema
+
+### PostgreSQL Tables (Datenbank `jarvis`)
+
+**users** (`init-db.sql`)
+- Felder: id, username, email, password_hash, api_key, role, is_active
+- Es gibt kein echtes Login-System pro Nutzer (siehe "Security" unten) - die
+  einzige vorhandene Zeile ist ein Seed-User `admin@jarvis.local` aus
+  `init-db.sql`. `ensure_default_user()` in `main.py` nimmt schlicht den
+  ersten User per ID als `DEFAULT_USER_ID` für alle Chat-Aktivität (in der
+  Praxis also dieser `admin`-Seed-User, nicht ein separat angelegter
+  "jarvis-service"-User, obwohl der Code-Pfad dafür existiert)
+
+**conversations** / **messages** (`init-db.sql`)
+- Chat-Verlauf, Multi-Turn über `conversation_id`
+- `messages.tokens_used` trackt Claude-Token-Verbrauch pro Antwort
+
+**tasks** (`init-db.sql`)
+- Tabelle existiert, wird aber von den `/api/v1/tasks`-Endpoints noch NICHT
+  genutzt (die sind aktuell Stubs mit hartcodierten Werten, siehe "API
+  Endpoints" unten) - offener Punkt für Phase 4b
+
+**documents** + **document_chunks** (`init-db.sql` + `migrations/002_document_chunks.sql`)
+- Knowledge Base fürs RAG: `documents` hält Titel/Volltext,
+  `document_chunks` die 768-dim `pgvector`-Embeddings (Ollama
+  `nomic-embed-text`) pro Chunk
+- `ivfflat`-Index wurde wieder entfernt (`003_drop_low_data_ivfflat_index.sql`),
+  da er bei wenig Daten 0 Treffer lieferte - aktuell Sequential Scan
+
+**weather_cache** (`migrations/004_weather_cache.sql`)
+- Wird ausschließlich vom n8n-Workflow "Wetter Crailsheim" befüllt (Cache,
+  kein Live-API-Call aus `main.py`)
+
+**email_cache** (`migrations/005_email_cache.sql`)
+- Wird ausschließlich vom n8n-Workflow "Neue E-Mails Cache" befüllt
+  (Absender/Betreff/Empfangsdatum, keine Volltexte). Der Chat greift für
+  Live-Anfragen separat direkt per IMAP zu, nicht über diesen Cache
+
+**audit_logs** (`init-db.sql`)
+- Tabelle existiert, wird aber aktuell von keinem Code-Pfad beschrieben
+  (vorbereitet für spätere Compliance-Anforderungen)
+
+### Redis
+- Läuft und wird im Health-Check geprüft (`check_redis()`), im Code aber
+  noch nirgends für Sessions/Caching/Queues genutzt - reiner Platzhalter für
+  spätere Erweiterung
+
+---
+
+## 🚀 API Endpoints
+
+Alle `/api/v1/*`-Routen (ausser keine - `/health` ist die einzige offene
+Route) verlangen den Header `X-Admin-Key: <API_KEY_ADMIN>`.
+
+### Health
+```
+GET  /health                          # Oeffentlich, kein Header noetig
+GET  /api/v1/admin/stats              # Conversations/Tasks/Documents-Zaehler
+GET  /api/v1/admin/health/detailed    # Postgres/Redis/Milvus(TCP-Check)/Ollama/n8n
+```
+
+### Chat (Claude, mit Tool Use für Kalender + E-Mail)
+```
+POST /api/v1/chat
+  Body: {"conversation_id": 1, "message": "...", "context": {}}
+  -> {"conversation_id", "response", "tokens_used", "timestamp"}
+
+GET  /api/v1/conversations/{id}       # Voller Nachrichtenverlauf
+```
+Claude kann in `run_chat_completion()` bis zu `MAX_TOOL_ROUNDS = 5` Tool-Runden
+hintereinander ausführen: `list_calendar_events`, `create_calendar_event`,
+`update_calendar_event`, `delete_calendar_event` (Löschen nur nach expliziter
+Chat-Bestätigung), `list_recent_emails`, `send_email` (Senden nur nach
+expliziter Chat-Bestätigung).
+
+### Kalender
+```
+GET  /api/v1/calendar/events?days=14  # Naechste Termine (Nextcloud CalDAV)
+```
+
+### Wetter
+```
+GET  /api/v1/weather                  # Neuester Cache-Eintrag (503 wenn leer)
+```
+
+### E-Mail
+```
+GET  /api/v1/emails?limit=10          # Neueste gecachte Mails ([] wenn leer, kein 503)
+```
+
+### Tasks (⚠️ noch nicht mit Postgres verbunden - TODO)
+```
+POST /api/v1/tasks                    # Stub: gibt immer id=1 zurueck, speichert nichts
+GET  /api/v1/tasks?status=pending     # Stub: gibt immer leere Liste zurueck
+```
+
+### Documents (Knowledge Base)
+```
+POST /api/v1/documents?title=...&content=...&document_type=...
+  # Chunking + Ollama-Embedding + Insert
+
+GET  /api/v1/documents?query=...&limit=10
+  # Vector-Similarity-Suche ueber document_chunks
+```
+
+### Workflows (⚠️ noch nicht mit n8n verbunden - TODO)
+```
+POST /api/v1/workflows/trigger        # Stub: ruft n8n nicht wirklich auf
+```
+
+---
+
+## 🔐 Security
+
+Es gibt **kein** vollwertiges Auth-System mit Login pro Nutzer. Stattdessen:
+- Frontend-Login = ein geteiltes Secret (`API_KEY_ADMIN`), das im Browser in
+  `localStorage` liegt und bei jedem Request als `X-Admin-Key`-Header
+  mitgeschickt wird (`require_admin_key`-Dependency in `main.py`)
+- Der `admin`-User in der `users`-Tabelle (aus `init-db.sql`) ist nur ein
+  DB-Seed für die `user_id`-Fremdschluessel, kein aktives Login - das Feld
+  `password_hash` wird von keinem Code-Pfad geprüft
+- Für ein echtes Multi-User-System (eigene Logins, Rollen) wäre eine
+  separate Architektur-Runde nötig - bewusst "Out of Scope" laut Frontend-Spec
+
+### Secrets (alle in `.env` auf dem VPS, nicht im Repo)
+- **API_KEY_ADMIN**: Shared Secret fürs Frontend-Login + alle geschützten API-Routen
+- **DB_PASSWORD**: Postgres-Passwort
+- **CLAUDE_API_KEY**: Anthropic API Key
+- **NEXTCLOUD_APP_PASSWORD**: Nextcloud CalDAV App-Passwort
+- **EMAIL_PASSWORD**: IMAP/SMTP-Passwort für kontakt@mbo-tech-it.de

+## 📊 Monitoring & Logs
+
+```bash
+# Real-time Logs
+docker compose logs -f
+
+# Logs für spezifischen Service
+docker compose logs -f jarvis-api
+
+# Alte Logs anschauen
+docker logs --tail 100 jarvis-api
+
+# System Resources
+docker stats
+```
+
+---
+
+## 🛠️ Troubleshooting
+
+### Container startet nicht
+```bash
+docker compose logs jarvis-api
+docker compose restart jarvis-api
+docker compose down && docker compose up -d
+```
+
+### Database Connection Error
+```bash
+docker exec jarvis-postgres pg_isready -U jarvis
+docker exec jarvis-postgres psql -U jarvis -d jarvis -c "SELECT 1"
+```
+
+### API antwortet nicht
+```bash
+docker compose ps
+curl -v http://localhost:8000/health
+docker compose logs jarvis-api
+```
+
+### Frontend zeigt eine neue Aenderung nicht an, obwohl deployt
+`web/nginx.conf` setzt `index.html` auf `no-cache` und `/assets/*` auf
+`immutable` - trotzdem: harter Reload (Strg+Shift+R) probieren, bevor man
+tiefer sucht. Ursache war einmal ein fehlender Cache-Header (siehe Phase 4d).
+
+### n8n-Workflow läuft nicht wie erwartet

+
+## 📈 Entwicklungsverlauf (chronologisch)
+
+### Phase 1: Grundsetup ✅
+- [x] Docker Stack deployed, alle Kern-Services laufen, Datenbank initialisiert, API verfügbar
+
+### Phase 2: KI-Integration ✅
+- [x] Claude API Key eingetragen (console.anthropic.com, separat vom Claude Pro Abo)
+- [x] Claude Integration in API (Multi-Turn ueber `conversation_id`)
+- [x] Token-Tracking implementiert (`tokens_used` pro Message + Response)
+- [x] Postgres-Persistenz fuer Conversations/Messages
+- [x] Echte Health-Checks (Postgres, Redis, Ollama, n8n; Milvus als TCP-Check vorbereitet)
+
+### Phase 3a: Knowledge Base ✅
+- [x] pgvector-Extension in Postgres (Image gewechselt auf `pgvector/pgvector:pg16`)
+- [x] `document_chunks`-Tabelle (768-dim Embeddings, Chunking 1000/100 Zeichen Overlap)
+- [x] Embeddings via Ollama `nomic-embed-text` (lokal, keine externen Kosten)
+- [x] `POST/GET /api/v1/documents` funktionsfaehig
+- [x] Bug gefunden+gefixt: `ivfflat`-Index lieferte bei wenig Daten 0 Treffer - Index vorerst entfernt, Sequential Scan aktiv
+- [ ] Follow-up: `ivfflat`/`hnsw`-Index neu anlegen, sobald genug Dokumente vorhanden sind
+
+### Phase 3b: Frontend ✅
+- [x] React/Vite Web UI (`jarvis-web` Container, nginx-served) unter https://jarvis.mbo-tech-it.de
+- [x] Shared-Secret-Login (wiederverwendet `API_KEY_ADMIN`, Header `X-Admin-Key`)
+- [x] Chat Interface (Multi-Turn) + Dashboard (Stats + Health-Tabelle)
+- [x] API auf eigene Subdomain umgezogen: https://api.jarvis.mbo-tech-it.de
+- [x] Bug gefixt (13.09.2026): Chat verlor Verlauf bei Tab-Wechsel/Reload, da
+      `conversationId` nur im React-State lag. Fix: `conversationId` in
+      `localStorage`, Verlauf wird beim Mounten via `GET /api/v1/conversations/{id}`
+      wiederhergestellt (`web/src/components/Chat.tsx`)
+- [ ] Vollwertiges User-/Auth-System (Login pro Nutzer, Rollen) - weiterhin offen
+
+### Phase 4a: Wetter-Widget ✅ (erster echter n8n-Workflow)
+- [x] n8n Owner-Account eingerichtet (`jonny@mbo-tech-it.de`)
+- [x] n8n-Workflow "Wetter Crailsheim" (id `BwNCJ2TkuZfqUzst`): Schedule-Trigger
+      (alle 30 Min) -> Open-Meteo API (kein Key noetig) -> Code-Node (WMO-Code
+      -> deutscher Text) -> Postgres-Insert in `weather_cache`
+- [x] n8n-Credential "JARVIS Postgres" (zeigt auf dieselbe `jarvis`-DB wie die API)
+- [x] `GET /api/v1/weather` liest die neueste Zeile
+- [x] `WeatherWidget` oben rechts in der Frontend-Nav-Leiste
+
+### Phase 4d: Nextcloud-Kalender-Integration ✅
+- [x] CalDAV-Zugriff auf `https://cloud.ffw-onza.de/.../ffw-onza-alle/` via
+      App-Passwort, Python-Library `caldav`
+- [x] `GET /api/v1/calendar/events` + "Naechste Termine"-Widget im Dashboard
+- [x] Chat kann Kalender abfragen, Termine anlegen und verschieben (direkt,
+      ohne Rueckfrage) sowie loeschen (nur nach Bestaetigung im Chat) -
+      Claude Tool Use mit `list_calendar_events` / `create_calendar_event` /
+      `update_calendar_event` / `delete_calendar_event`
+- [x] Bug gefixt (13.09.2026): `run_chat_completion` unterstuetzte nur eine
+      Tool-Runde - "Termin verschieben" braucht aber zwei (erst uid per
+      `list_calendar_events` finden, dann `update_calendar_event`), die
+      zweite Runde wurde still verworfen (leere Antwort). Jetzt eine echte
+      Schleife (`MAX_TOOL_ROUNDS = 5`)
+- [x] Bug gefixt: neu angelegte Termine landeten als UTC statt Europe/Berlin
+      (2h Verschiebung) - naive Datumswerte werden jetzt explizit lokalisiert
+      (`_as_calendar_local`)
+- [x] Bug gefixt: `web/nginx.conf` hatte keine Cache-Header - `index.html`
+      wurde vom Browser gecacht, wodurch ein Deploy im Browser nicht ankam,
+      obwohl der Server bereits den neuen Build auslieferte. Jetzt:
+      `index.html` = `no-cache`, `/assets/*` = `immutable`
+
+### Phase 4e: Sprach-Ein-/Ausgabe im Chat ✅
+- [x] Mikrofon-Button (🎤) nutzt die Browser-eigene Web Speech API
+      (`SpeechRecognition`, `de-DE`) - reine Frontend-Loesung, blendet sich
+      selbst aus, wenn der Browser das nicht unterstuetzt (v.a. Firefox)
+- [x] Assistant-Antworten werden automatisch per `SpeechSynthesis`
+      vorgelesen, Standard "an"; Mute-Button (🔊/🔇) merkt sich Zustand in
+      `localStorage` (`jarvis_speech_muted`)
+- [x] Neues Modul `web/src/speech.ts` buendelt beide APIs (nach Vorbild von `api.ts`)
+- [x] Bug gefixt (13.09.2026): `continuous=false` beendete die Erkennung bei
+      jeder Sprechpause. Jetzt `continuous=true` mit automatischem Neustart
+      bei Chrome's internem Session-Timeout (akkumuliert Text ueber
+      Neustarts hinweg, damit nichts verloren geht)
+- [x] Sprachausgabe filtert vor dem Vorlesen: Emojis (inkl. Zahlen-Emoji wie
+      1⃣2⃣3⃣), Markdown-Formatierung (`**fett**`, `#Ueberschriften`) und
+      dekorative Trennlinien/Tabellenzeichen (`---`, `═══`, `|`) - siehe
+      `cleanForSpeech()` in `web/src/speech.ts`
+
+### Phase 4f: E-Mail-Integration ✅
+- [x] Postfach `kontakt@mbo-tech-it.de` (IMAP `mx2f35.netcup.net:143` STARTTLS,
+      SMTP `mx2f35.netcup.net:465` implizites TLS) via Python-Standardbibliothek
+      (`imaplib`, `smtplib`, `email`) angebunden - keine neue Dependency
+- [x] Chat-Tools `list_recent_emails` (liest live per IMAP, `BODY.PEEK` damit
+      der Lese-Status nicht veraendert wird, RFC-2047-Betreffs dekodiert) und
+      `send_email` (SMTP_SSL) in `run_chat_completion()`, analog zum Kalender.
+      `send_email` verlangt wie `delete_calendar_event` immer erst eine
+      Bestaetigung im Chat, bevor tatsaechlich versendet wird
+- [x] n8n-Workflow "Neue E-Mails Cache" (id `VaAQdw18ElYWkEfr`, aktiv):
+      eingebauter `Email Trigger (IMAP)`-Node (`postProcessAction: "nothing"`,
+      damit das Cachen den echten Lese-Status im Postfach nicht veraendert)
+      -> Postgres-Insert in `email_cache` (nur Metadaten, keine Volltexte)
+- [x] `GET /api/v1/emails` liest die neuesten Zeilen; leerer Cache liefert
+      `[]` statt 503 (anders als beim Wetter kein Fehlerzustand)
+- [x] `EmailWidget` ("Neue E-Mails") im Dashboard, nach demselben Muster wie
+      `CalendarWidget`/`WeatherWidget`
+- [x] Live end-to-end getestet: Chat hat echte Inbox-Mails aufgelistet,
+      Testmail per Chat mit Bestaetigungsdialog versendet und im Postfach
+      verifiziert, n8n-Workflow hat dieselbe Mail in `email_cache` erfasst,
+      Dashboard-Widget zeigt sie an
+- [x] Kleiner Fix waehrend der Verifikation: von JARVIS selbst versendete
+      Mails hatten keinen `Date`-Header (smtplib/EmailMessage setzt den nicht
+      automatisch) - `_send_email_sync` setzt jetzt `Date` und `Message-ID`
+- Out of Scope (siehe Spec): Anhaenge, Antworten/Weiterleiten, Loeschen/
+  Verschieben von Mails, mehrere Postfaecher/Ordner
+
+### Phase 4b: Weitere Automation ⏳ (offen)
+- [ ] `POST/GET /api/v1/tasks` an die vorhandene `tasks`-Tabelle anbinden (aktuell Stub)
+- [ ] `POST /api/v1/workflows/trigger` tatsaechlich an die n8n-API anbinden (aktuell Stub)
+- [ ] Weitere n8n Business-Workflows definieren (Kundenbericht-Automation o.ä.)
+
+### Phase 5: Production ⏳ (offen)
+- [ ] Backup-Strategie (Postgres-Dumps automatisieren, aktuell nur manuell per `pg_dump`)
+- [ ] Monitoring & Alerts (aktuell nur manuelles Ansehen von `/api/v1/admin/health/detailed`)
+- [ ] Sicherheits-Hardening / echtes Multi-User-Auth-System

+
+```bash
+# Domain
+DOMAIN=jarvis.mbo-tech-it.de
+
+# Database
+DB_PASSWORD=SecurePassword123!
+
+# KI / LLM
+CLAUDE_API_KEY=sk-ant-...
+OLLAMA_MODEL=mistral
+
+# Security
+JWT_SECRET=random-secret-key
+API_KEY_ADMIN=admin-api-key
+
+# Logging
+LOG_LEVEL=info
+```
+
+## Häufige Befehle
+
+```bash
+cd /home/jarvis-core/jarvis
+
+# Alle Container starten
+docker-compose up -d
+
+# Spezifischen Service neu starten
+docker-compose restart jarvis-api
+
+# Logs ansehen
+docker-compose logs -f jarvis-api
+
+# In Container gehen
+docker-compose exec jarvis-api bash
+
+# Database mit psql verbinden
+docker-compose exec postgres psql -U jarvis -d jarvis
+
+# Alle Container stoppen
+docker-compose down
+
+# Mit Daten löschen (Vorsicht!)
+docker-compose down -v
+```
+
+## Integration mit Claude API
+
+### Python-Client Beispiel
+
+```python
+import os
+import anthropic
+
+client = anthropic.Anthropic(api_key=os.getenv("CLAUDE_API_KEY"))
+
+message = client.messages.create(
+    model="claude-3-5-sonnet-20241022",
+    max_tokens=1024,
+    messages=[
+        {"role": "user", "content": "Deine Frage"}
+    ]
+)
+
+print(message.content[0].text)
+```
+
+## n8n Workflows
+
+### Beispiel-Automation: Kundenbericht generieren
+1. Trigger: Zeitplan (täglich)
+2. Node: PostgreSQL - Daten abrufen
+3. Node: Claude API - Bericht generieren
+4. Node: PDF generieren
+5. Node: Email versenden
+
+## Security Best Practices
+
+✅ **Production Ready:**
+- [ ] HTTPS/SSL konfigurieren (Let's Encrypt)
+- [ ] Firewall-Regeln (nur erlaubte IPs)
+- [ ] Secrets in .env nicht in Git
+- [ ] Regelmäßige DB-Backups
+- [ ] Monitoring & Alerts einrichten
+- [ ] Rate Limiting aktivieren
+- [ ] API-Keys rotieren
+
+⚠️ **Aktuell (Test):**
+- HTTP nur lokal/intern
+- Standard-Passwörter (ÄNDERN!)
+- Keine Authentifizierung erzwungen
+
+## Troubleshooting
+
+### Container startet nicht
+```bash
+docker-compose logs jarvis-api
+# → Fehlerlog prüfen
+```
+
+### Datenbank nicht erreichbar
+```bash
+docker-compose exec postgres psql -U jarvis -d jarvis -c "SELECT 1"
+```
+
+### Redis Cache Fehler
+```bash
+docker-compose exec redis redis-cli ping
+# → PONG = OK
+```
+
+### Milvus Vector DB Fehler
+```bash
+docker-compose exec milvus curl http://localhost:9091/healthz
+```
+
+## Monitoring
+
+```bash
+# System-Stats
+docker stats
+
+# Container Logs (real-time)
+docker-compose logs -f
+
+# Health Check
+curl http://localhost:8000/health
+curl http://localhost:8000/api/v1/admin/health/detailed
+```
+
+## Nächste Schritte
+
+1. ✅ Docker-Stack deployed
+2. ⏳ Claude API Integration (Python)
+3. ⏳ Web-Frontend (React/Vue)
+4. ⏳ n8n Workflows konfigurieren
+5. ⏳ Knowledge Base aufbauen
+6. ⏳ Production Deployment (SSL, Backups, etc.)

+# JARVIS Knowledge Base (Phase 3) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the TODO-stub `POST/GET /api/v1/documents` endpoints with a real document-upload + semantic-search knowledge base, backed by pgvector in the existing Postgres instance and Ollama for embeddings.
+
+**Architecture:** Documents are chunked (character-based, with overlap) on upload, each chunk is embedded via Ollama's `nomic-embed-text` model, and stored in a new `document_chunks` table (pgvector column). Search embeds the query the same way and ranks chunks by cosine distance (`<=>`).
+
+**Tech Stack:** FastAPI, psycopg2 (existing `db_query` helper), pgvector Postgres extension, aiohttp (existing Ollama HTTP pattern), pytest (new, local-only dev dependency).
+
+**Spec:** `docs/superpowers/specs/2026-09-12-knowledge-base-design.md`
+
+## Global Constraints
+
+- No dedicated git repository exists for this project yet (the working directory sits inside an unrelated, very large home-directory-level repo that must not be touched). **Every "Commit" step below is replaced by "confirm the file is saved" — do not run `git add`/`git commit`.**
+- Runtime is the live VPS at `72.61.186.98`, container `jarvis-api` (image `python:3.11-slim`, code bind-mounted from `/home/jarvis-core/jarvis/api`, `uvicorn --reload`). SSH: `ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98`. Local files live in `Claude outputs/` (note the space — quote the path in shell commands) and must be scp'd to `/home/jarvis-core/jarvis/...` to take effect.
+- Reuse the existing `db_query(query, params, fetch)` async helper in `main.py` for all DB access — do not introduce an ORM.
+- Follow the existing code style in `main.py`: section comments (`# ============ X ============`), try/except around endpoint bodies that logs and raises `HTTPException`, async endpoints.
+- Embedding model: `nomic-embed-text` (768 dimensions) — this fixes the `vector(768)` column width used below.
+- Chunking: ~1000 characters, 100 character overlap (from the spec) — do not change these defaults without updating the spec.
+
+---
+
+### Task 1: pgvector extension + `document_chunks` table
+
+**Files:**
+- Modify: `Claude outputs/docker-compose.yml` (postgres image)
+- Create: `Claude outputs/migrations/002_document_chunks.sql`
+
+**Interfaces:**
+- Produces: Postgres table `document_chunks(id, document_id, chunk_index, content, embedding vector(768), created_at)`, used by Task 4 and Task 5's DB helpers.
+
+**Context:** the plain `postgres:16-alpine` image does not ship the pgvector extension. `pgvector/pgvector:pg16` is a drop-in image (built from postgres:16) with the extension precompiled — swapping the image and recreating the container is safe, the existing `postgres_data` volume is untouched.
+
+- [ ] **Step 1: Swap the Postgres image to the pgvector-enabled build**
+
+Edit `Claude outputs/docker-compose.yml`:
+
+```yaml
+  postgres:
+    image: pgvector/pgvector:pg16
+```
+
+(only the `image:` line under the `postgres:` service changes — everything else stays as-is).
+
+- [ ] **Step 2: Deploy the compose change and recreate the postgres container**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+scp $SSHOPTS "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs\docker-compose.yml" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/docker-compose.yml
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose up -d postgres && sleep 5 && docker compose ps postgres"
+```
+
+Expected: `jarvis-postgres` shows `Up ... (healthy)` with the new image.
+
+- [ ] **Step 3: Write the migration file**
+
+Create `Claude outputs/migrations/002_document_chunks.sql`:
+
+```sql
+CREATE EXTENSION IF NOT EXISTS vector;
+
+CREATE TABLE document_chunks (
+    id SERIAL PRIMARY KEY,
+    document_id INTEGER NOT NULL REFERENCES documents(id) ON DELETE CASCADE,
+    chunk_index INTEGER NOT NULL,
+    content TEXT NOT NULL,
+    embedding vector(768) NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_document_chunks_document_id ON document_chunks(document_id);
+CREATE INDEX idx_document_chunks_embedding ON document_chunks
+    USING ivfflat (embedding vector_cosine_ops) WITH (lists = 100);
+```
+
+- [ ] **Step 4: Apply the migration to the live database**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+scp $SSHOPTS "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs\migrations\002_document_chunks.sql" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/migrations/002_document_chunks.sql
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker exec -i jarvis-postgres psql -U jarvis -d jarvis < /home/jarvis-core/jarvis/migrations/002_document_chunks.sql"
+```
+
+Expected output ends with `CREATE INDEX` (no errors). If `CREATE EXTENSION` fails with "could not open extension control file", Step 1/2 didn't take effect — re-check the image was actually swapped (`docker inspect jarvis-postgres | grep Image`).
+
+- [ ] **Step 5: Verify**
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker exec jarvis-postgres psql -U jarvis -d jarvis -c '\d document_chunks'"
+```
+
+Expected: column list showing `embedding | vector(768)` among others.
+
+- [ ] **Step 6: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 2: Chunking function (TDD)
+
+**Files:**
+- Modify: `Claude outputs/main.py` (add `chunk_text`)
+- Test: `Claude outputs/tests/test_chunking.py`
+- Create: `Claude outputs/requirements-dev.txt`
+
+**Interfaces:**
+- Produces: `chunk_text(text: str, chunk_size: int = 1000, overlap: int = 100) -> list[str]` in `main.py`, consumed by Task 4's upload endpoint.
+
+- [ ] **Step 1: Add pytest as a local-only dev dependency**
+
+Create `Claude outputs/requirements-dev.txt`:
+
+```
+pytest==8.3.3
+```
+
+- [ ] **Step 2: Install it locally**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+python -m pip install -r requirements-dev.txt -r requirements.txt
+```
+
+- [ ] **Step 3: Write the failing tests**
+
+Create `Claude outputs/tests/test_chunking.py`:
+
+```python
+import sys
+import os
+
+sys.path.insert(0, os.path.join(os.path.dirname(__file__), ".."))
+
+from main import chunk_text
+
+
+def test_chunk_text_empty_returns_empty_list():
+    assert chunk_text("") == []
+
+
+def test_chunk_text_shorter_than_chunk_size_returns_single_chunk():
+    assert chunk_text("hello", chunk_size=1000, overlap=100) == ["hello"]
+
+
+def test_chunk_text_exact_multiple_of_chunk_size():
+    text = "a" * 20
+    chunks = chunk_text(text, chunk_size=10, overlap=2)
+    assert chunks == [text[0:10], text[8:18], text[16:20]]
+```
+
+- [ ] **Step 4: Run tests to verify they fail**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+python -m pytest tests/test_chunking.py -v
+```
+
+Expected: FAIL with `ImportError: cannot import name 'chunk_text'` (or similar — `chunk_text` doesn't exist yet). Note: importing `main.py` will also try to import `psycopg2`, `redis`, `anthropic`, `aiohttp` — these must already be installed locally via Step 2 for the import to get far enough to fail on `chunk_text` specifically, not on a missing package.
+
+- [ ] **Step 5: Implement `chunk_text`**
+
+In `Claude outputs/main.py`, add near the other pure helpers (e.g. above `# ============ DB HELPERS ============`):
+
+```python
+def chunk_text(text: str, chunk_size: int = 1000, overlap: int = 100) -> list:
+    if not text:
+        return []
+    if len(text) <= chunk_size:
+        return [text]
+    chunks = []
+    step = chunk_size - overlap
+    start = 0
+    while start < len(text):
+        end = start + chunk_size
+        chunks.append(text[start:end])
+        if end >= len(text):
+            break
+        start += step
+    return chunks
+```
+
+- [ ] **Step 6: Run tests to verify they pass**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+python -m pytest tests/test_chunking.py -v
+```
+
+Expected: 3 passed.
+
+- [ ] **Step 7: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 3: Ollama embedding helper
+
+**Files:**
+- Modify: `Claude outputs/main.py` (add `OLLAMA_EMBED_MODEL` config + `get_embedding`)
+- Modify: `Claude outputs/docker-compose.yml` (jarvis-api environment)
+
+**Interfaces:**
+- Consumes: `OLLAMA_HOST` (already defined in `main.py`), `aiohttp` (already imported).
+- Produces: `async def get_embedding(text: str) -> list` in `main.py`, consumed by Task 4 and Task 5.
+
+- [ ] **Step 1: Add the embed-model config constant**
+
+In `Claude outputs/main.py`, next to the other `# ============ CONFIG ============` constants:
+
+```python
+OLLAMA_EMBED_MODEL = os.getenv("OLLAMA_EMBED_MODEL", "nomic-embed-text")
+```
+
+- [ ] **Step 2: Add `get_embedding`**
+
+In `Claude outputs/main.py`, add after `chunk_text`:
+
+```python
+async def get_embedding(text: str) -> list:
+    timeout = aiohttp.ClientTimeout(total=30)
+    async with aiohttp.ClientSession(timeout=timeout) as session:
+        async with session.post(
+            f"{OLLAMA_HOST}/api/embeddings",
+            json={"model": OLLAMA_EMBED_MODEL, "prompt": text},
+        ) as resp:
+            if resp.status != 200:
+                body = await resp.text()
+                raise RuntimeError(f"Ollama embedding failed ({resp.status}): {body}")
+            data = await resp.json()
+            return data["embedding"]
+```
+
+- [ ] **Step 3: Add `OLLAMA_EMBED_MODEL` to the deployed environment**
+
+In `Claude outputs/docker-compose.yml`, under `jarvis-api: environment:`, add a line next to `OLLAMA_HOST`:
+
+```yaml
+      - OLLAMA_EMBED_MODEL=nomic-embed-text
+```
+
+- [ ] **Step 4: Confirm files saved** (no automated test here — `get_embedding` is verified end-to-end in Task 4; see Global Constraints for why there's no commit step)
+
+---
+
+### Task 4: Wire up document upload
+
+**Files:**
+- Modify: `Claude outputs/main.py` (`insert_document`, `insert_document_chunks`, `upload_document`)
+
+**Interfaces:**
+- Consumes: `chunk_text` (Task 2), `get_embedding` (Task 3), `db_query` (existing), `DEFAULT_USER_ID` (existing global).
+- Produces: DB helpers `insert_document(title, content, document_type) -> int` and `insert_document_chunks(document_id: int, chunks: list) -> None`, where `chunks` is `list[tuple[str, list]]` of `(chunk_text, embedding)` pairs.
+
+- [ ] **Step 1: Add a vector-literal formatting helper and the DB helpers**
+
+In `Claude outputs/main.py`, add near the other DB helpers (after `save_message`):
+
+```python
+def _vector_literal(embedding: list) -> str:
+    return "[" + ",".join(repr(float(x)) for x in embedding) + "]"
+
+
+async def insert_document(title: str, content: str, document_type: str) -> int:
+    row = await db_query(
+        "INSERT INTO documents (user_id, title, content, document_type) VALUES (%s, %s, %s, %s) RETURNING id",
+        (DEFAULT_USER_ID, title, content, document_type),
+        fetch="one",
+    )
+    return row["id"]
+
+
+async def insert_document_chunks(document_id: int, chunks: list):
+    for index, (content, embedding) in enumerate(chunks):
+        await db_query(
+            """

+            (document_id, index, content, _vector_literal(embedding)),
+        )
+```
+
+- [ ] **Step 2: Replace the `upload_document` endpoint**
+
+In `Claude outputs/main.py`, replace the existing stub:
+
+```python
+@app.post("/api/v1/documents")
+async def upload_document(title: str, content: str, document_type: str = "general"):
+    """Upload document to knowledge base"""
+    if not pg_pool:

+        document_id = await insert_document(title, content, document_type)
+        chunks = chunk_text(content)
+        embedded_chunks = [(c, await get_embedding(c)) for c in chunks]
+        await insert_document_chunks(document_id, embedded_chunks)

+
+### Task 5: Wire up document search + end-to-end verification
+
+**Files:**
+- Modify: `Claude outputs/main.py` (`search_chunks`, `search_documents`)
+
+**Interfaces:**
+- Consumes: `get_embedding` (Task 3), `db_query` (existing).
+- Produces: DB helper `search_chunks(query_embedding: list, limit: int) -> list[dict]`.
+
+- [ ] **Step 1: Add the search DB helper**
+
+In `Claude outputs/main.py`, add next to `insert_document_chunks`:

+# JARVIS Weather Widget Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Expose the weather data the new n8n workflow writes to Postgres via a protected API endpoint, and show it top-right in the frontend nav bar.
+
+**Architecture:** `GET /api/v1/weather` reads the newest row from `weather_cache` (already populated by the "Wetter Crailsheim" n8n workflow, verified working). A new `WeatherWidget` React component polls that endpoint and renders in the nav bar.
+
+**Tech Stack:** FastAPI (existing `db_query`/`require_admin_key` patterns), React (existing `apiFetch` pattern).
+
+**Spec:** `docs/superpowers/specs/2026-09-12-weather-widget-design.md`
+
+## Global Constraints

+- No dedicated git repository for this project (see prior plans) — every "Commit" step is replaced by "confirm the file is saved".
+- SSH: `ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98`. Local backend files: `Claude outputs/` (quote the path). Local frontend files: `web/`.
+- The n8n workflow "Wetter Crailsheim" (id `BwNCJ2TkuZfqUzst`), its Postgres credential "JARVIS Postgres", and the `weather_cache` table already exist and are verified working (one row present from a manual test run) — this plan does not touch them.
+- `weather_cache` schema: `id, location, temperature_c NUMERIC, condition_code INTEGER, condition_text VARCHAR(100), fetched_at TIMESTAMP`.
+- The endpoint must use `dependencies=[Depends(require_admin_key)]` like every other `/api/v1/*` route (see `Claude outputs/main.py`).

+    with patch.object(main, "pg_pool", "not-none"), patch.object(
+        main, "get_latest_weather", new=AsyncMock(return_value=row)
+    ):
+        response = client.get("/api/v1/weather", headers=HEADERS)
+    assert response.status_code == 200
+    assert response.json()["location"] == "Crailsheim"
+
+
+def test_weather_requires_admin_key(client):
+    response = client.get("/api/v1/weather")
+    assert response.status_code == 401
+```
+
+Note: `patch.object(main, "pg_pool", "not-none")` stands in for "database configured" — the endpoint only checks `if not pg_pool`, so any truthy value works without needing a real connection pool.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "mkdir -p /tmp/jarvis-test/tests"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" "$OUT/requirements.txt" "$OUT/requirements-dev.txt" jarvis-core@72.61.186.98:/tmp/jarvis-test/
+scp $SSHOPTS "$OUT/tests/test_weather.py" jarvis-core@72.61.186.98:/tmp/jarvis-test/tests/
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker run --rm -v /tmp/jarvis-test:/app -w /app python:3.11-slim bash -c 'pip install -q -r requirements-dev.txt -r requirements.txt && python -m pytest tests/test_weather.py -v'"
+```
+
+Expected: FAIL — `get_latest_weather` doesn't exist / `/api/v1/weather` is 404.
+
+- [ ] **Step 3: Add the DB helper and endpoint**
+
+In `Claude outputs/main.py`, add near the other DB helpers (after `search_chunks`):
+
+```python
+async def get_latest_weather():
+    return await db_query(
+        """
+        SELECT location, temperature_c, condition_text, fetched_at
+        FROM weather_cache ORDER BY fetched_at DESC LIMIT 1
+        """,
+        fetch="one",
+    )
+```
+
+Add the endpoint near the other admin/status endpoints (after `detailed_health`):
+
+```python
+@app.get("/api/v1/weather", dependencies=[Depends(require_admin_key)])
+async def get_weather():
+    """Latest cached weather reading, populated by the n8n 'Wetter Crailsheim' workflow"""
+    if not pg_pool:
+        raise HTTPException(status_code=503, detail="Database is not configured")
+
+    row = await get_latest_weather()
+    if not row:
+        raise HTTPException(status_code=503, detail="Weather data not available yet")
+
+    return {
+        "location": row["location"],
+        "temperature_c": float(row["temperature_c"]),
+        "condition_text": row["condition_text"],
+        "fetched_at": row["fetched_at"].isoformat(),
+    }
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Re-run the Step 2 command. Expected: 3 passed.
+
+- [ ] **Step 5: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/api/main.py
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose restart jarvis-api && sleep 8 && docker logs --tail 15 jarvis-api"
+```
+
+Expected: log ends with `Application startup complete.` (no traceback). Then:
+
+```bash
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -H 'X-Admin-Key: $ADMIN_KEY' http://localhost:8000/api/v1/weather; echo"
+```
+
+Expected: JSON with `"location":"Crailsheim"` and the temperature/condition from the test run done during n8n workflow setup.
+
+- [ ] **Step 6: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 2: `WeatherWidget` in the nav bar
+
+**Files:**
+- Create: `web/src/components/WeatherWidget.tsx`
+- Modify: `web/src/App.tsx` (render the widget in the nav)
+- Modify: `web/src/index.css` (right-align the widget in the nav)
+
+**Interfaces:**
+- Consumes: `apiFetch` from `./api` (existing), `GET /api/v1/weather` (Task 1).
+- Produces: `WeatherWidget` default export, no props, rendered inside the existing `<nav className="nav">` in `App.tsx`.
+
+- [ ] **Step 1: Add the nav CSS for right-alignment**
+
+In `web/src/index.css`, add after the `.nav button` rule:
+
+```css
+.weather-widget { margin-left: auto; font-size: 0.9rem; color: #94a3b8; align-self: center; }
+```
+
+- [ ] **Step 2: Create the component**
+
+Create `web/src/components/WeatherWidget.tsx`:
+
+```tsx
+import { useEffect, useState } from "react";
+import { apiFetch } from "../api";
+
+type Weather = { location: string; temperature_c: number; condition_text: string };
+
+const REFRESH_MS = 5 * 60 * 1000;
+
+export default function WeatherWidget() {
+  const [weather, setWeather] = useState<Weather | null>(null);
+  const [failed, setFailed] = useState(false);
+
+  useEffect(() => {
+    let cancelled = false;
+
+    async function load() {
+      try {
+        const response = await apiFetch("/api/v1/weather");
+        if (!response.ok) {
+          if (!cancelled) setFailed(true);
+          return;
+        }
+        const data = await response.json();
+        if (!cancelled) {
+          setWeather(data);
+          setFailed(false);
+        }
+      } catch {
+        if (!cancelled) setFailed(true);
+      }
+    }
+
+    load();
+    const interval = setInterval(load, REFRESH_MS);
+    return () => {
+      cancelled = true;
+      clearInterval(interval);
+    };
+  }, []);
+
+  if (failed) {
+    return <span className="weather-widget">Wetter nicht verfuegbar</span>;
+  }
+  if (!weather) {
+    return null;
+  }
+
+  return (
+    <span className="weather-widget">
+      {`${weather.location}: ${weather.temperature_c.toFixed(1)}\u00b0C \u00b7 ${weather.condition_text}`}
+    </span>
+  );
+}
+```
+
+- [ ] **Step 3: Render it in the nav bar**
+
+In `web/src/App.tsx`, add the import next to the other component imports:
+
+```tsx
+import WeatherWidget from "./components/WeatherWidget";
+```
+
+Change the `<nav>` block from:
+
+```tsx
+      <nav className="nav">
+        <button onClick={() => setView("chat")} disabled={view === "chat"}>Chat</button>
+        <button onClick={() => setView("dashboard")} disabled={view === "dashboard"}>Dashboard</button>
+        <button onClick={() => logout()}>Logout</button>
+      </nav>
+```
+
+to:
+
+```tsx
+      <nav className="nav">
+        <button onClick={() => setView("chat")} disabled={view === "chat"}>Chat</button>
+        <button onClick={() => setView("dashboard")} disabled={view === "dashboard"}>Dashboard</button>
+        <button onClick={() => logout()}>Logout</button>
+        <WeatherWidget />
+      </nav>
+```
+
+- [ ] **Step 4: Verify the build works**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm run build
+```
+
+Expected: exits 0.
+
+- [ ] **Step 5: Deploy**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS"
+scp $SSHOPTS -r "$OUT\web\src" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/web/
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose build jarvis-web && docker compose up -d jarvis-web"
+```
+
+- [ ] **Step 6: End-to-end browser verification**
+
+Using the claude-in-chrome browser tools: open `https://jarvis.mbo-tech-it.de`, log in with the real `API_KEY_ADMIN`, confirm the weather text (e.g. "Crailsheim: 20.9°C · Bewoelkt") appears top-right of the nav bar on both the Chat and Dashboard views.
+
+- [ ] **Step 7: Confirm files saved** (no git repo for this project — see Global Constraints)

+# JARVIS Web Frontend (Phase 3b) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a React/Vite web frontend (Chat + Dashboard) for JARVIS, protected by a shared-secret gate, served on `jarvis.mbo-tech-it.de` while the API moves to `api.jarvis.mbo-tech-it.de`.
+
+**Architecture:** A shared-secret FastAPI dependency (`require_admin_key`) protects the existing API endpoints. A separate React/Vite SPA (new `jarvis-web` Docker service, nginx-served) calls that API from the browser, storing the shared secret in `localStorage` and attaching it as `X-Admin-Key` on every call.
+
+**Tech Stack:** FastAPI (existing), React + Vite + TypeScript (new), Vitest (frontend unit tests), pytest + FastAPI TestClient + httpx (backend unit test), nginx:alpine (static serving), Docker multi-stage build.
+
+**Spec:** `docs/superpowers/specs/2026-09-12-web-frontend-design.md`
+
+## Global Constraints
+
+- No dedicated git repository for this project (see prior plans' Global Constraints) — every "Commit" step below is replaced by "confirm the file is saved"; do not run `git add`/`git commit`.
+- Runtime is the live VPS at `72.61.186.98`. SSH: `ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98`. Local backend files live in `Claude outputs/` (note the space — quote the path), local frontend files go in a new `web/` directory at the project root (`C:\Users\Jonny\Projekte\Claude\JARVIS\web`).
+- Reuse the existing `API_KEY_ADMIN` secret already generated in the deployed `.env` — do not create a new secret.
+- Auth header name is `X-Admin-Key` (exact casing as written; HTTP headers are case-insensitive but FastAPI's `Header()` parameter name `x_admin_key` maps to it automatically).
+- Domain split: `jarvis.mbo-tech-it.de` → frontend, `api.jarvis.mbo-tech-it.de` → API. Both are covered by the existing `*.jarvis.mbo-tech-it.de` wildcard DNS record — no new DNS entries needed.
+- `GET /health` stays unprotected (monitoring). Every other `/api/v1/*` route gets the auth dependency.
+- Local toolchain confirmed available: Node v24.14.0 / npm 11.9.0 (frontend, runs natively on this Windows machine); Python 3.14 locally cannot build `psycopg2-binary` (no wheel yet) — backend tests that import `main.py` must run inside a `python:3.11-slim` container, same pattern as the knowledge-base plan: `docker run --rm -v <dir>:/app -w /app python:3.11-slim bash -c '...'` (or via SSH on the VPS, which already has this image cached, if local Docker Desktop isn't running).
+
+---
+
+### Task 1: Backend access control
+
+**Files:**
+- Modify: `Claude outputs/main.py` (CORS, `API_KEY_ADMIN` config, `require_admin_key` dependency, route decorators)
+- Modify: `Claude outputs/docker-compose.yml` (jarvis-api environment)
+- Create: `Claude outputs/requirements-dev.txt` (add `httpx` if not already present)
+- Test: `Claude outputs/tests/test_auth.py`
+
+**Interfaces:**
+- Produces: `require_admin_key` FastAPI dependency in `main.py`, applied via `dependencies=[Depends(require_admin_key)]` on every protected route. Later tasks (frontend) rely on the header name `X-Admin-Key` and on `GET /health` remaining open.
+
+- [ ] **Step 1: Add `httpx` to the dev requirements** (needed for FastAPI's `TestClient`)
+
+Read `Claude outputs/requirements-dev.txt` first (it currently contains `pytest==8.3.3` from the knowledge-base plan). Append:
+
+```
+httpx==0.27.2
+```
+
+- [ ] **Step 2: Write the failing tests**
+
+Create `Claude outputs/tests/test_auth.py`:
+
+```python
+import os
+import sys
+
+sys.path.insert(0, os.path.join(os.path.dirname(__file__), ".."))
+
+import pytest
+from fastapi.testclient import TestClient
+
+import main
+
+main.API_KEY_ADMIN = "test-secret"
+
+
+@pytest.fixture()
+def client():
+    with TestClient(main.app) as c:
+        yield c
+
+
+def test_missing_key_returns_401(client):
+    response = client.get("/api/v1/admin/stats")
+    assert response.status_code == 401
+
+
+def test_wrong_key_returns_401(client):
+    response = client.get("/api/v1/admin/stats", headers={"X-Admin-Key": "nope"})
+    assert response.status_code == 401
+
+
+def test_correct_key_passes_auth_gate(client):
+    response = client.get("/api/v1/admin/stats", headers={"X-Admin-Key": "test-secret"})
+    assert response.status_code != 401
+
+
+def test_health_stays_open_without_key(client):
+    response = client.get("/health")
+    assert response.status_code != 401
+```
+
+- [ ] **Step 3: Run tests to verify they fail**
+
+Using a local Docker container (fastest path if Docker Desktop is running):
+
+```bash
+docker run --rm -v "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs:/app" -w /app python:3.11-slim bash -c "pip install -q -r requirements-dev.txt -r requirements.txt && python -m pytest tests/test_auth.py -v"
+```
+
+If Docker Desktop isn't running locally, run the same command over SSH against the VPS instead (copy the files to a scratch dir first, matching the pattern used for the chunking tests):
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "mkdir -p /tmp/jarvis-test/tests"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" "$OUT/requirements.txt" "$OUT/requirements-dev.txt" jarvis-core@72.61.186.98:/tmp/jarvis-test/
+scp $SSHOPTS "$OUT/tests/test_auth.py" jarvis-core@72.61.186.98:/tmp/jarvis-test/tests/
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker run --rm -v /tmp/jarvis-test:/app -w /app python:3.11-slim bash -c 'pip install -q -r requirements-dev.txt -r requirements.txt && python -m pytest tests/test_auth.py -v'"
+```
+
+Expected: FAIL — `require_admin_key` doesn't exist yet, or (once it exists but isn't wired up) the 401 assertions fail because routes aren't protected yet.
+
+- [ ] **Step 4: Add the config constant and dependency**
+
+In `Claude outputs/main.py`, change the fastapi import line:
+
+```python
+from fastapi import FastAPI, HTTPException
+```
+
+to:
+
+```python
+from fastapi import FastAPI, HTTPException, Depends, Header
+```
+
+Add the config constant next to the other `# ============ CONFIG ============` constants:
+
+```python
+API_KEY_ADMIN = os.getenv("API_KEY_ADMIN")
+```
+
+Add the dependency function right after the CORS `app.add_middleware(...)` block:
+
+```python
+async def require_admin_key(x_admin_key: Optional[str] = Header(default=None)):
+    if not API_KEY_ADMIN or x_admin_key != API_KEY_ADMIN:
+        raise HTTPException(status_code=401, detail="Invalid or missing admin key")
+```
+
+- [ ] **Step 5: Tighten CORS**
+
+In `Claude outputs/main.py`, change:
+
+```python
+app.add_middleware(
+    CORSMiddleware,
+    allow_origins=["*"],
+    allow_credentials=True,
+    allow_methods=["*"],
+    allow_headers=["*"],
+)
+```
+
+to:
+
+```python
+app.add_middleware(
+    CORSMiddleware,
+    allow_origins=["https://jarvis.mbo-tech-it.de"],
+    allow_credentials=True,
+    allow_methods=["*"],
+    allow_headers=["*"],
+)
+```
+
+- [ ] **Step 6: Protect every `/api/v1/*` route**
+
+In `Claude outputs/main.py`, change each of these decorator lines (leave the function bodies untouched):
+
+```python
+@app.post("/api/v1/chat", response_model=ChatResponse)
+```
+→
+```python
+@app.post("/api/v1/chat", response_model=ChatResponse, dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.get("/api/v1/conversations/{conversation_id}")
+```
+→
+```python
+@app.get("/api/v1/conversations/{conversation_id}", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.post("/api/v1/tasks", response_model=TaskResponse)
+```
+→
+```python
+@app.post("/api/v1/tasks", response_model=TaskResponse, dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.get("/api/v1/tasks")
+```
+→
+```python
+@app.get("/api/v1/tasks", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.post("/api/v1/documents")
+```
+→
+```python
+@app.post("/api/v1/documents", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.get("/api/v1/documents")
+```
+→
+```python
+@app.get("/api/v1/documents", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.post("/api/v1/workflows/trigger")
+```
+→
+```python
+@app.post("/api/v1/workflows/trigger", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.get("/api/v1/admin/stats")
+```
+→
+```python
+@app.get("/api/v1/admin/stats", dependencies=[Depends(require_admin_key)])
+```
+
+```python
+@app.get("/api/v1/admin/health/detailed")
+```
+→
+```python
+@app.get("/api/v1/admin/health/detailed", dependencies=[Depends(require_admin_key)])
+```
+
+Leave `@app.get("/health")` exactly as-is (unprotected).
+
+- [ ] **Step 7: Run tests to verify they pass**
+
+Re-run the same command from Step 3. Expected: 4 passed.
+
+- [ ] **Step 8: Wire `API_KEY_ADMIN` into the deployed container environment**
+
+In `Claude outputs/docker-compose.yml`, under `jarvis-api: environment:`, add a line next to `CLAUDE_API_KEY`:
+
+```yaml
+      - API_KEY_ADMIN=${API_KEY_ADMIN:-}
+```
+
+- [ ] **Step 9: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/api/main.py
+scp $SSHOPTS "$OUT/docker-compose.yml" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/docker-compose.yml
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose up -d jarvis-api && sleep 8 && docker logs --tail 20 jarvis-api"
+```
+
+Expected: log ends with `Application startup complete.` (no traceback).
+
+Then confirm the gate is live (replace `<ADMIN_KEY>` with the real value from the deployed `.env`'s `API_KEY_ADMIN`):
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -o /dev/null -w 'no key: %{http_code}\n' http://localhost:8000/api/v1/admin/stats"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -o /dev/null -w 'health (open): %{http_code}\n' http://localhost:8000/health"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env"
+```
+
+Take the printed `API_KEY_ADMIN` value and confirm it now works:
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -o /dev/null -w 'with key: %{http_code}\n' -H 'X-Admin-Key: <ADMIN_KEY>' http://localhost:8000/api/v1/admin/stats"
+```
+
+Expected: `no key: 401`, `health (open): 200`, `with key: 200`.
+
+- [ ] **Step 10: Confirm files saved** (no git repo for this project — see Global Constraints)
+

+
+### Task 2: Frontend scaffold + API client
+
+**Files:**
+- Create: `web/package.json`, `web/tsconfig.json`, `web/vite.config.ts`, `web/index.html`, `web/.env.production`
+- Create: `web/src/main.tsx`, `web/src/App.tsx` (placeholder), `web/src/index.css`
+- Create: `web/src/api.ts`
+- Test: `web/src/api.test.ts`
+
+**Interfaces:**
+- Produces: `apiFetch(path, options?, keyOverride?)`, `getStoredKey()`, `storeKey(key)`, `clearKey()`, `logout()`, `onUnauthorized(handler)`, `UnauthorizedError` — all exported from `web/src/api.ts`. Task 3 (Login/App) and Tasks 4-5 (Chat/Dashboard) import these.
+
+- [ ] **Step 1: Create the project scaffold**
+
+Create `web/package.json`:

+
+```typescript
+import { describe, it, expect, beforeEach, vi } from "vitest";
+import { apiFetch, storeKey, getStoredKey, UnauthorizedError } from "./api";
+

+
+- [ ] **Step 4: Run tests to verify they fail**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm test
+```
+
+Expected: FAIL — `./api` module doesn't exist yet.
+
+- [ ] **Step 5: Implement `api.ts`**
+
+Create `web/src/api.ts`:
+
+```typescript
+const STORAGE_KEY = "jarvis_admin_key";
+const UNAUTHORIZED_EVENT = "jarvis:unauthorized";
+
+export class UnauthorizedError extends Error {}
+
+function getApiBase(): string {

+  if (key) {
+    headers.set("X-Admin-Key", key);
+  }
+  const response = await fetch(`${getApiBase()}${path}`, { ...options, headers });
+  if (response.status === 401) {
+    clearKey();
+    window.dispatchEvent(new Event(UNAUTHORIZED_EVENT));
+    throw new UnauthorizedError("Invalid or missing admin key");
+  }
+  return response;
+}
+```
+
+- [ ] **Step 6: Run tests to verify they pass**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm test
+```
+
+Expected: 2 passed.
+
+- [ ] **Step 7: Verify the build works end to end**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm run build
+```
+
+Expected: exits 0, produces a `dist/` directory.
+
+- [ ] **Step 8: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 3: Login screen + app gate
+
+**Files:**
+- Create: `web/src/components/Login.tsx`
+- Modify: `web/src/App.tsx` (replace placeholder)
+
+**Interfaces:**
+- Consumes: `apiFetch`, `storeKey`, `getStoredKey`, `onUnauthorized`, `logout`, `UnauthorizedError` from `./api` (Task 2).
+- Produces: `App` default export used by `main.tsx` (Task 2, unchanged); `Login` component with props `{ onSuccess: () => void }`, used by `App.tsx` and later referenced by Tasks 4-5's parent (`App.tsx` renders `Chat`/`Dashboard` once authenticated — those components take no props).
+
+- [ ] **Step 1: Create the Login component**
+
+Create `web/src/components/Login.tsx`:
+
+```tsx
+import { useState, FormEvent } from "react";
+import { apiFetch, storeKey, UnauthorizedError } from "../api";
+
+export default function Login({ onSuccess }: { onSuccess: () => void }) {
+  const [password, setPassword] = useState("");
+  const [error, setError] = useState<string | null>(null);
+  const [checking, setChecking] = useState(false);
+
+  async function handleSubmit(e: FormEvent) {
+    e.preventDefault();
+    setError(null);
+    setChecking(true);
+    try {
+      const response = await apiFetch("/api/v1/admin/stats", {}, password);
+      if (response.ok) {
+        storeKey(password);
+        onSuccess();
+      } else {
+        setError("Login fehlgeschlagen.");
+      }
+    } catch (err) {
+      if (err instanceof UnauthorizedError) {
+        setError("Falsches Passwort.");
+      } else {
+        setError("Server nicht erreichbar.");
+      }
+    } finally {
+      setChecking(false);
+    }
+  }
+
+  return (
+    <form onSubmit={handleSubmit} className="login">
+      <h1>JARVIS</h1>
+      <input
+        type="password"
+        value={password}
+        onChange={(e) => setPassword(e.target.value)}
+        placeholder="Passwort"
+        autoFocus
+      />
+      <button type="submit" disabled={checking || password.length === 0}>
+        {checking ? "Pruefe..." : "Anmelden"}
+      </button>
+      {error && <p className="error">{error}</p>}
+    </form>
+  );
+}
+```
+
+- [ ] **Step 2: Replace the `App.tsx` placeholder**
+
+Replace the contents of `web/src/App.tsx`:
+
+```tsx
+import { useState, useEffect } from "react";
+import { getStoredKey, onUnauthorized, logout } from "./api";
+import Login from "./components/Login";
+import Chat from "./components/Chat";
+import Dashboard from "./components/Dashboard";
+
+type View = "chat" | "dashboard";
+
+export default function App() {
+  const [authenticated, setAuthenticated] = useState<boolean>(() => getStoredKey() !== null);
+  const [view, setView] = useState<View>("chat");
+
+  useEffect(() => onUnauthorized(() => setAuthenticated(false)), []);
+
+  if (!authenticated) {
+    return <Login onSuccess={() => setAuthenticated(true)} />;
+  }
+
+  return (
+    <div className="app">
+      <nav className="nav">
+        <button onClick={() => setView("chat")} disabled={view === "chat"}>Chat</button>
+        <button onClick={() => setView("dashboard")} disabled={view === "dashboard"}>Dashboard</button>
+        <button onClick={() => logout()}>Logout</button>
+      </nav>
+      {view === "chat" ? <Chat /> : <Dashboard />}
+    </div>
+  );
+}
+```
+
+Note: this references `./components/Chat` and `./components/Dashboard`, which don't exist until Tasks 4 and 5. The build will fail until both exist — that's expected; Step 3 below uses a temporary stub to verify Login in isolation first.
+
+- [ ] **Step 3: Verify with temporary stubs, then leave real work to Tasks 4-5**
+
+Create temporary placeholder files so the build can succeed and Login can be verified in isolation (Tasks 4 and 5 will overwrite these with the real implementation):
+
+Create `web/src/components/Chat.tsx`:
+
+```tsx
+export default function Chat() {
+  return <p>Chat placeholder</p>;
+}
+```
+
+Create `web/src/components/Dashboard.tsx`:
+
+```tsx
+export default function Dashboard() {
+  return <p>Dashboard placeholder</p>;
+}
+```
+
+- [ ] **Step 4: Verify the build works**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"

+- Produces: `Chat` default export, no props (rendered by `App.tsx` from Task 3).
+
+- [ ] **Step 1: Replace the Chat placeholder**

+### Task 6: Docker packaging, Traefik routing, deploy, end-to-end verification
+
+**Files:**
+- Create: `web/Dockerfile`, `web/nginx.conf`
+- Modify: `Claude outputs/docker-compose.yml` (jarvis-api router rule, new `jarvis-web` service)
+
+**Interfaces:**
+- Consumes: `web/` (Tasks 2-5), `Claude outputs/docker-compose.yml`'s existing `proxy-network` external network (already defined from the knowledge-base/Traefik-integration work).
+
+- [ ] **Step 1: Create the Dockerfile**
+
+Create `web/Dockerfile`:
+
+```dockerfile
+FROM node:20-slim AS build
+WORKDIR /app
+COPY package.json package-lock.json* ./
+RUN npm install
+COPY . .
+RUN npm run build
+
+FROM nginx:alpine
+COPY --from=build /app/dist /usr/share/nginx/html
+COPY nginx.conf /etc/nginx/conf.d/default.conf
+EXPOSE 80
+```
+
+- [ ] **Step 2: Create the nginx SPA config**
+
+Create `web/nginx.conf`:
+
+```nginx
+server {
+    listen 80;
+    server_name _;
+    root /usr/share/nginx/html;
+    index index.html;
+
+    location / {

+
+- [ ] **Step 3: Move the API's Traefik router to `api.jarvis.mbo-tech-it.de`**
+
+In `Claude outputs/docker-compose.yml`, under the `jarvis-api` service's `labels:`, change:
+
+```yaml
+      - "traefik.http.routers.jarvis-api.rule=Host(`${DOMAIN:-localhost}`)"

+```yaml
+      - "traefik.http.routers.jarvis-api.rule=Host(`api.${DOMAIN:-localhost}`)"
+```
+
+- [ ] **Step 4: Add the `jarvis-web` service**
+
+In `Claude outputs/docker-compose.yml`, add a new service after `jarvis-api` (before the `networks:` top-level key):
+
+```yaml
+  jarvis-web:
+    build:
+      context: ./web
+      dockerfile: Dockerfile

+```
+
+Expected: both containers `Up`.
+
+- [ ] **Step 6: Verify the API moved correctly**
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -o /dev/null -w 'api.jarvis health: %{http_code}\n' https://api.jarvis.mbo-tech-it.de/health --max-time 15"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -o /dev/null -w 'old jarvis root (should now 404 from Traefik or serve web): %{http_code}\n' https://jarvis.mbo-tech-it.de/health --max-time 15"
+```
+
+Expected: `api.jarvis health: 200`. The second call hits the new web frontend's nginx (not the API), so `/health` there returns nginx's SPA fallback (`index.html`, HTTP 200) rather than the JSON health payload — that's expected, since `/health` is an API route, not a frontend route.
+
+- [ ] **Step 7: Verify the web frontend loads**
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s https://jarvis.mbo-tech-it.de --max-time 15 | grep -o '<title>[^<]*</title>'"
+```
+
+Expected: `<title>JARVIS</title>`.
+
+- [ ] **Step 8: End-to-end browser verification**
+
+Using the claude-in-chrome browser tools (load them via `ToolSearch` with query `select:mcp__claude-in-chrome__tabs_context_mcp,mcp__claude-in-chrome__navigate,mcp__claude-in-chrome__computer,mcp__claude-in-chrome__read_page,mcp__claude-in-chrome__tabs_create_mcp` if not already loaded):
+
+1. Create a new tab, navigate to `https://jarvis.mbo-tech-it.de`.
+2. Enter a wrong password and submit — confirm "Falsches Passwort." appears.
+3. Enter the real `API_KEY_ADMIN` value (from `Claude outputs/.env` fetched in Task 1 Step 9, or re-fetch with `ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env"`) and submit — confirm the Chat view appears (nav bar with Chat/Dashboard/Logout).
+4. Type a message (e.g. "Sag in einem Satz, dass du JARVIS bist.") and send — confirm a user bubble and an assistant reply both appear.
+5. Click "Dashboard" — confirm the three stat cards render with numbers and the health table shows rows for `postgres`, `redis`, `ollama`, `n8n`, `milvus` (milvus expected `error`, matching current infra state), `api`.
+6. Click "Logout" — confirm the app returns to the login screen.
+

+# JARVIS Nextcloud Calendar Integration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Give JARVIS read/write access to the Nextcloud "FFW-Onza-Alle" CalDAV calendar: a dashboard widget listing upcoming events, and chat-driven querying + confirmed event creation via Claude tool use.
+
+**Architecture:** A `caldav`-backed helper pair (`list_upcoming_events`, `create_event`) wrapped in `asyncio.to_thread` (same pattern as the existing Postgres `db_query` helper). A new protected `GET /api/v1/calendar/events` endpoint serves the dashboard widget. `/api/v1/chat` gains two Claude tools that call the same helpers, with a system-prompt rule requiring explicit user confirmation before any write.
+
+**Tech Stack:** `caldav` + `icalendar` (Python, new dependencies), FastAPI (existing `require_admin_key`/`db_query` patterns), Anthropic Messages API tool use, React (existing `apiFetch` pattern).
+
+**Spec:** `docs/superpowers/specs/2026-09-13-calendar-integration-design.md`
+
+## Global Constraints
+
+- No dedicated git repository for this project — every "Commit" step is replaced by "confirm the file is saved".
+- SSH: `ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98`. Backend files: `Claude outputs/`. Frontend files: `web/`.
+- CalDAV connectivity is already verified working (13.09.2026): read found 11 real events, a test event was created and deleted successfully using the exact credentials below.
+- Credentials (already provided, put in `.env` — never hardcode in source): `NEXTCLOUD_CALDAV_URL=https://cloud.ffw-onza.de/remote.php/dav/calendars/jonny/ffw-onza-alle/`, `NEXTCLOUD_USER=jonny`, `NEXTCLOUD_APP_PASSWORD=j9Ywc-9Pnbk-8rQQw-Qnkb2-ZoqQJ`.
+- The DAV client root is derived from the calendar URL by splitting on `/calendars/`: `dav_root = NEXTCLOUD_CALDAV_URL.split("/calendars/")[0] + "/"` — this produces `https://cloud.ffw-onza.de/remote.php/dav/`, verified against the real server.
+- An all-day event's `dtstart` is a plain `date`, not `datetime` — `isinstance(dtstart, datetime)` is `False` for those (datetime is a subclass of date, so this check is reliable both ways).
+- `create_calendar_event` must never be called by Claude without the user first confirming in the conversation — enforced via system-prompt instruction (see spec's "Sicherheit" section), not a technical gate.
+- Tool-use intermediate turns (the `tool_use`/`tool_result` exchange) are never persisted to the `messages` table — only the final visible user/assistant pair, matching existing persistence behavior.
+
+---
+
+### Task 1: CalDAV helpers + config + unit tests
+
+**Files:**
+- Modify: `Claude outputs/main.py` (imports, config constants, `_caldav_calendar`, `list_upcoming_events`, `create_event`)
+- Modify: `Claude outputs/requirements.txt` (add `caldav`, `icalendar`)
+- Modify: `Claude outputs/docker-compose.yml` (jarvis-api environment)
+- Test: `Claude outputs/tests/test_calendar.py`
+
+**Interfaces:**
+- Produces: `async def list_upcoming_events(days_ahead: int) -> list` returning `[{"summary": str, "start": iso_str, "end": iso_str, "description": str, "all_day": bool}, ...]` sorted by start; `async def create_event(summary: str, start: str, end: str, description: str = "") -> dict` returning `{"summary", "start", "end", "description"}`. Consumed by Task 2 (endpoint) and Task 3 (chat tools).
+
+- [ ] **Step 1: Add dependencies**
+
+In `Claude outputs/requirements.txt`, add two lines:
+
+```
+caldav
+icalendar
+```
+
+(Unpinned, like `anthropic` — these are new enough that a pinned version chosen without checking PyPI risks picking one that doesn't exist; pip resolves the current compatible release at container build time.)
+
+- [ ] **Step 2: Write the failing tests**
+
+Create `Claude outputs/tests/test_calendar.py`:
+
+```python
+import os
+import sys
+from datetime import datetime, date
+from unittest.mock import MagicMock, patch
+
+sys.path.insert(0, os.path.join(os.path.dirname(__file__), ".."))

+    comp["dtstart"] = _Val(dtstart_value)
+    comp["dtend"] = _Val(dtend_value)

+    def get(key, default=None):
+        return comp.get(key, default)

+    fake = MagicMock()
+    fake.get = get

+
+
+def test_list_upcoming_events_maps_timed_and_all_day_events():

+    )
+    all_day = MagicMock()
+    all_day.icalendar_component = _fake_component(
+        "Volksfestwache", date(2026, 9, 19), date(2026, 9, 20)
+    )
+
+    fake_calendar = MagicMock()
+    fake_calendar.search.return_value = [all_day, timed]  # unsorted on purpose
+
+    with patch.object(main, "_caldav_calendar", return_value=fake_calendar):
+        events = main._list_upcoming_events_sync(14)
+
+    assert [e["summary"] for e in events] == ["THL FM LS", "Volksfestwache"]
+    assert events[0]["all_day"] is False
+    assert events[1]["all_day"] is True
+
+
+def test_create_event_calls_save_event_with_parsed_dates():
+    fake_calendar = MagicMock()
+
+    with patch.object(main, "_caldav_calendar", return_value=fake_calendar):
+        result = main._create_event_sync(
+            "JARVIS Testtermin", "2026-09-20T10:00:00", "2026-09-20T11:00:00", "desc"
+        )
+
+    fake_calendar.save_event.assert_called_once()
+    _, kwargs = fake_calendar.save_event.call_args
+    assert kwargs["summary"] == "JARVIS Testtermin"
+    assert kwargs["dtstart"] == datetime(2026, 9, 20, 10, 0, 0)
+    assert result["summary"] == "JARVIS Testtermin"
+```
+
+- [ ] **Step 3: Run tests to verify they fail**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "mkdir -p /tmp/jarvis-test/tests"

+```
+
+Expected: FAIL — `_caldav_calendar`/`_list_upcoming_events_sync`/`_create_event_sync` don't exist yet.
+
+- [ ] **Step 4: Add config constants**
+
+In `Claude outputs/main.py`, change the datetime import line:
+
+```python
+from datetime import datetime
+```
+
+to:
+
+```python
+from datetime import datetime, timedelta
+```
+
+Add near the top, after the other `import` lines (after `import aiohttp`):
+
+```python
+import caldav
+```
+
+Add near the other `# ============ CONFIG ============` constants:
+
+```python
+NEXTCLOUD_CALDAV_URL = os.getenv("NEXTCLOUD_CALDAV_URL")
+NEXTCLOUD_USER = os.getenv("NEXTCLOUD_USER")
+NEXTCLOUD_APP_PASSWORD = os.getenv("NEXTCLOUD_APP_PASSWORD")
+```
+
+- [ ] **Step 5: Add the CalDAV helpers**
+
+In `Claude outputs/main.py`, add after `get_latest_weather` (the last DB helper):
+
+```python
+def _caldav_calendar():
+    dav_root = NEXTCLOUD_CALDAV_URL.split("/calendars/")[0] + "/"
+    client = caldav.DAVClient(url=dav_root, username=NEXTCLOUD_USER, password=NEXTCLOUD_APP_PASSWORD)
+    return client.calendar(url=NEXTCLOUD_CALDAV_URL)
+
+
+def _list_upcoming_events_sync(days_ahead: int) -> list:
+    calendar = _caldav_calendar()
+    start = datetime.now()
+    end = start + timedelta(days=days_ahead)
+    results = calendar.search(start=start, end=end, event=True, expand=True)
+    events = []
+    for result in results:
+        comp = result.icalendar_component
+        dtstart = comp.get("dtstart").dt
+        dtend_prop = comp.get("dtend")
+        dtend = dtend_prop.dt if dtend_prop else dtstart
+        events.append(
+            {
+                "summary": str(comp.get("summary", "")),
+                "start": dtstart.isoformat(),
+                "end": dtend.isoformat(),
+                "description": str(comp.get("description", "")),
+                "all_day": not isinstance(dtstart, datetime),
+            }
+        )
+    events.sort(key=lambda e: e["start"])
+    return events
+
+
+async def list_upcoming_events(days_ahead: int) -> list:
+    return await asyncio.to_thread(_list_upcoming_events_sync, days_ahead)
+
+
+def _create_event_sync(summary: str, start: str, end: str, description: str = "") -> dict:
+    calendar = _caldav_calendar()
+    calendar.save_event(
+        dtstart=datetime.fromisoformat(start),
+        dtend=datetime.fromisoformat(end),
+        summary=summary,
+        description=description,
+    )
+    return {"summary": summary, "start": start, "end": end, "description": description}
+
+
+async def create_event(summary: str, start: str, end: str, description: str = "") -> dict:
+    return await asyncio.to_thread(_create_event_sync, summary, start, end, description)
+```
+
+- [ ] **Step 6: Run tests to verify they pass**
+
+Re-run the Step 3 command. Expected: 2 passed.
+
+- [ ] **Step 7: Wire the CalDAV env vars into the deployed container**
+
+In `Claude outputs/docker-compose.yml`, under `jarvis-api: environment:`, add after `API_KEY_ADMIN`:
+
+```yaml
+      - NEXTCLOUD_CALDAV_URL=https://cloud.ffw-onza.de/remote.php/dav/calendars/jonny/ffw-onza-alle/
+      - NEXTCLOUD_USER=jonny
+      - NEXTCLOUD_APP_PASSWORD=${NEXTCLOUD_APP_PASSWORD:-}
+```
+
+Then add the actual password to the deployed `.env` (not `docker-compose.yml`, which stays committed-safe with the `${...}` reference):
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "grep -q NEXTCLOUD_APP_PASSWORD /home/jarvis-core/jarvis/.env || echo 'NEXTCLOUD_APP_PASSWORD=j9Ywc-9Pnbk-8rQQw-Qnkb2-ZoqQJ' >> /home/jarvis-core/jarvis/.env"
+```
+
+- [ ] **Step 8: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 2: `GET /api/v1/calendar/events` endpoint
+
+**Files:**
+- Modify: `Claude outputs/main.py` (add the endpoint)
+
+**Interfaces:**
+- Consumes: `list_upcoming_events` (Task 1).
+- Produces: `GET /api/v1/calendar/events?days=14` returning `{"events": [...]}`, `503` on CalDAV failure. Consumed by Task 4's frontend widget.
+
+- [ ] **Step 1: Add the endpoint**
+
+In `Claude outputs/main.py`, add after the `get_weather` endpoint (end of file, before `if __name__ == "__main__":`):
+
+```python
+@app.get("/api/v1/calendar/events", dependencies=[Depends(require_admin_key)])
+async def get_calendar_events(days: int = 14):
+    """Upcoming events from the FFW-Onza-Alle Nextcloud calendar"""
+    try:
+        events = await list_upcoming_events(days)
+        return {"events": events}
+    except Exception as e:
+        logger.error(f"Calendar fetch error: {str(e)}")
+        raise HTTPException(status_code=503, detail=f"Calendar unavailable: {str(e)}")
+```
+
+- [ ] **Step 2: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" "$OUT/requirements.txt" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/api/

+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose up -d jarvis-api && sleep 10 && docker logs --tail 20 jarvis-api"
+```
+
+Expected: log ends with `Application startup complete.` (no traceback — the container reinstalls `requirements.txt` on every start, so `caldav`/`icalendar` get pulled in automatically).
+
+```bash
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -H 'X-Admin-Key: $ADMIN_KEY' 'http://localhost:8000/api/v1/calendar/events?days=30'; echo"
+```
+
+Expected: JSON with an `events` array containing real entries (e.g. "THL FM LS", "Volksfestwache" — the same events found during the connectivity check).
+
+- [ ] **Step 3: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 3: Chat tool use (query + confirmed create)
+
+**Files:**
+- Modify: `Claude outputs/main.py` (imports, tool definitions, `execute_tool`, `run_chat_completion`, rewire `chat()`)
+- Test: `Claude outputs/tests/test_chat_tools.py`
+
+**Interfaces:**
+- Consumes: `list_upcoming_events`, `create_event` (Task 1), `claude_client`, `CLAUDE_MODEL` (existing).
+- Produces: `async def run_chat_completion(claude_messages: list) -> tuple[str, int, int]` returning `(response_text, output_tokens, total_tokens)`. Replaces the inline `claude_client.messages.create` call in `chat()`.
+
+- [ ] **Step 1: Write the failing test**
+
+Create `Claude outputs/tests/test_chat_tools.py`:
+
+```python

+```
+
+Note: this test file needs `pytest-asyncio` to run `async def test_...` functions — add it to `Claude outputs/requirements-dev.txt` in this step (append `pytest-asyncio==0.24.0`), and create `Claude outputs/pytest.ini` with:

+- [ ] **Step 3: Add `import json`**
+
+In `Claude outputs/main.py`, add `import json` next to `import logging`.

+
+- [ ] **Step 6: Run tests to verify they pass**
+
+Re-run the Step 2 command. Expected: 2 passed.
+
+- [ ] **Step 7: Rewire `chat()` to use it**
+
+In `Claude outputs/main.py`, inside `chat()`, replace:
+
+```python
+        completion = await asyncio.to_thread(
+            claude_client.messages.create,

+
+        await save_message(conversation_id, DEFAULT_USER_ID, "assistant", response_text, output_tokens)
+```
+
+- [ ] **Step 8: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"
+scp $SSHOPTS "$OUT/main.py" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/api/main.py

+```
+
+Expected: log ends with `Application startup complete.` (no traceback). Then:
+
+```bash
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -X POST http://localhost:8000/api/v1/chat -H 'Content-Type: application/json' -H 'X-Admin-Key: $ADMIN_KEY' -d '{\"message\": \"Was steht in den naechsten 30 Tagen im Kalender an?\"}'; echo"
+```
+
+Expected: a natural-language response mentioning real events from the calendar (e.g. "THL FM LS", "Volksfestwache") — proof the tool round-trip actually executed against the live Nextcloud calendar, not a hallucinated answer.
+
+- [ ] **Step 9: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 4: "Nächste Termine" dashboard widget
+
+**Files:**
+- Create: `web/src/components/CalendarWidget.tsx`
+- Modify: `web/src/components/Dashboard.tsx` (render it)
+
+**Interfaces:**
+- Consumes: `apiFetch` (existing), `GET /api/v1/calendar/events` (Task 2).
+- Produces: `CalendarWidget` default export, no props, rendered inside `Dashboard`.
+
+- [ ] **Step 1: Create the widget**
+
+Create `web/src/components/CalendarWidget.tsx`:
+
+```tsx
+import { useEffect, useState } from "react";
+import { apiFetch } from "../api";
+
+type CalendarEvent = { summary: string; start: string; all_day: boolean };
+
+export default function CalendarWidget() {
+  const [events, setEvents] = useState<CalendarEvent[] | null>(null);
+  const [error, setError] = useState<string | null>(null);
+
+  useEffect(() => {
+    async function load() {
+      try {
+        const response = await apiFetch("/api/v1/calendar/events?days=14");
+        if (!response.ok) {
+          setError("Kalender nicht verfuegbar");
+          return;
+        }
+        const data = await response.json();
+        setEvents(data.events);
+      } catch {
+        setError("Kalender nicht verfuegbar");
+      }
+    }
+    load();
+  }, []);
+
+  function formatEvent(e: CalendarEvent): string {
+    const date = new Date(e.start);
+    const dateStr = date.toLocaleDateString("de-DE", { day: "2-digit", month: "2-digit" });
+    if (e.all_day) return `${dateStr}: ${e.summary}`;
+    const timeStr = date.toLocaleTimeString("de-DE", { hour: "2-digit", minute: "2-digit" });
+    return `${dateStr} ${timeStr}: ${e.summary}`;
+  }
+
+  return (
+    <div className="calendar-widget">
+      <h3>N\u00e4chste Termine</h3>
+      {error && <p className="error">{error}</p>}
+      {events && events.length === 0 && <p>Keine Termine in den n\u00e4chsten 14 Tagen.</p>}
+      {events && events.length > 0 && (
+        <ul>
+          {events.map((e, i) => (
+            <li key={i}>{formatEvent(e)}</li>
+          ))}
+        </ul>
+      )}
+    </div>
+  );
+}
+```
+
+- [ ] **Step 2: Render it in the Dashboard**
+
+In `web/src/components/Dashboard.tsx`, add the import next to the other imports:
+
+```tsx
+import CalendarWidget from "./CalendarWidget";
+```
+
+Add `<CalendarWidget />` right after the closing `</table>` of the health table, still inside the outer `<div className="dashboard">`.
+
+- [ ] **Step 3: Verify the build works**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm run build
+```
+
+Expected: exits 0.
+
+- [ ] **Step 4: Deploy**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS"
+scp $SSHOPTS -r "$OUT\web\src" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/web/
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose build jarvis-web && docker compose up -d jarvis-web"
+```
+
+- [ ] **Step 5: End-to-end browser verification**
+
+Using the claude-in-chrome browser tools: log in at `https://jarvis.mbo-tech-it.de`, open Dashboard, confirm "Nächste Termine" lists real events (e.g. "THL FM LS"). Then in Chat, ask "Was steht diese Woche im Kalender an?" and confirm a real-data answer. Then say something like "Leg einen Termin 'JARVIS Verbindungstest' am 25.09.2026 von 14 bis 15 Uhr an" and confirm JARVIS asks for confirmation before creating anything; confirm it, then verify the event actually appears (re-query the widget or the calendar endpoint) — afterwards delete that test event directly against the calendar (reuse the connectivity-check pattern: a one-off `caldav` script via `docker run python:3.11-slim`, searching by summary and calling `.delete()`) so the real organisation calendar stays clean.

+# JARVIS Email Integration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Give JARVIS read/send access to the `kontakt@mbo-tech-it.de` mailbox: chat-driven live reading and confirmed sending, plus an n8n-cached "new emails" dashboard widget.
+
+**Architecture:** `imaplib`/`smtplib` (Python stdlib, no new dependency) power two new Claude tools in `run_chat_completion` (`list_recent_emails`, `send_email`). A separate n8n workflow using the built-in `Email Trigger (IMAP)` node caches new-message metadata into a new `email_cache` table for a dashboard widget, independent of the chat tools.
+
+**Tech Stack:** `imaplib`, `smtplib`, `email` (all Python stdlib), FastAPI (existing patterns), Anthropic tool use (existing `run_chat_completion` loop), n8n REST API, React.
+
+**Spec:** `docs/superpowers/specs/2026-09-13-email-integration-design.md`
+
+## Global Constraints
+
+- No dedicated git repository — every "Commit" step is replaced by "confirm the file is saved".
+- SSH: `ssh -F /dev/null -o IdentitiesOnly=yes -i ~/.ssh/jarvis_core_key jarvis-core@72.61.186.98`. Backend: `Claude outputs/`. Frontend: `web/`.
+- Credentials (already verified working 13.09.2026): `EMAIL_IMAP_HOST=mx2f35.netcup.net`, `EMAIL_IMAP_PORT=143` (STARTTLS), `EMAIL_SMTP_HOST=mx2f35.netcup.net`, `EMAIL_SMTP_PORT=465` (implicit SSL), `EMAIL_USER=kontakt@mbo-tech-it.de`, `EMAIL_PASSWORD=E%21gq10i` (literal string, not URL-encoded).
+- `send_email` must never be called by Claude without the user first confirming recipient/subject/body in the conversation — enforced via system-prompt instruction, same pattern as `delete_calendar_event`.
+- n8n already has a credential "JARVIS Postgres" (id `8b6g9X080UhxUgLv`) pointing at the `jarvis` database, and a fresh credential "JARVIS Email IMAP" (id `4rU5KYIv1sKCJkAd`) already created with the above IMAP settings (`secure: false`, since STARTTLS on port 143 is used, not implicit TLS) — reuse both, don't recreate.
+- The n8n API key from the weather workflow setup is expired/inaccessible; a new one ("JARVIS Email Workflow") was created during spec verification but its value wasn't persisted anywhere durable — generate a fresh one via the n8n UI (Settings → n8n API) when Task 4 needs it, same procedure as the weather workflow.
+- n8n's `n8n-nodes-base.emailReadImap` (Email Trigger IMAP) node is confirmed present in this n8n version, with a `postProcessAction: "nothing"` option that must be used so caching doesn't mark real business emails as read.
+
+---
+
+### Task 1: IMAP/SMTP helpers + config + unit tests
+
+**Files:**
+- Modify: `Claude outputs/main.py` (imports, config constants, `_decode_mime_words`, `_list_recent_emails_sync`/`list_recent_emails`, `_send_email_sync`/`send_email`)
+- Modify: `Claude outputs/docker-compose.yml` (jarvis-api environment)
+- Test: `Claude outputs/tests/test_email.py`
+
+**Interfaces:**
+- Produces: `async def list_recent_emails(limit: int = 10) -> list` returning `[{"from": str, "subject": str, "date": str, "unread": bool}, ...]`, newest first; `async def send_email(to: str, subject: str, body: str) -> dict` returning `{"to", "subject", "sent": True}`. Consumed by Task 3 (chat tools).
+
+- [ ] **Step 1: Write the failing tests**
+
+Create `Claude outputs/tests/test_email.py`:

+
+Expected: FAIL — `_list_recent_emails_sync`/`_send_email_sync` don't exist yet.
+
+- [ ] **Step 3: Add imports and config constants**
+
+In `Claude outputs/main.py`, add near the other imports (after `import caldav`):

+- [ ] **Step 6: Wire the email env vars into the deployed container**
+
+In `Claude outputs/docker-compose.yml`, under `jarvis-api: environment:`, add after `NEXTCLOUD_APP_PASSWORD`:
+
+```yaml
+      - EMAIL_IMAP_HOST=mx2f35.netcup.net
+      - EMAIL_IMAP_PORT=143
+      - EMAIL_SMTP_HOST=mx2f35.netcup.net
+      - EMAIL_SMTP_PORT=465
+      - EMAIL_USER=kontakt@mbo-tech-it.de
+      - EMAIL_PASSWORD=${EMAIL_PASSWORD:-}
+```
+
+Add the password to the deployed `.env`:
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ssh $SSHOPTS jarvis-core@72.61.186.98 "grep -q EMAIL_PASSWORD /home/jarvis-core/jarvis/.env || echo 'EMAIL_PASSWORD=E%21gq10i' >> /home/jarvis-core/jarvis/.env"
+```
+
+- [ ] **Step 7: Confirm files saved** (no git repo for this project — see Global Constraints)
+

+
+### Task 2: `email_cache` table + `GET /api/v1/emails` endpoint
+
+**Files:**
+- Create: `Claude outputs/migrations/005_email_cache.sql`
+- Modify: `Claude outputs/main.py` (add `get_latest_emails` DB helper + endpoint)
+
+**Interfaces:**
+- Produces: `GET /api/v1/emails?limit=10` returning `{"emails": [...]}`, each `{"sender", "subject", "received_at"}`. Consumed by Task 5's dashboard widget. Populated by Task 4's n8n workflow.
+
+- [ ] **Step 1: Create and apply the migration**
+
+Create `Claude outputs/migrations/005_email_cache.sql`:
+
+```sql
+CREATE TABLE email_cache (
+    id SERIAL PRIMARY KEY,
+    sender VARCHAR(255) NOT NULL,
+    subject VARCHAR(500) NOT NULL,
+    received_at TIMESTAMP NOT NULL,
+    cached_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_email_cache_received_at ON email_cache(received_at);
+```
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+scp $SSHOPTS "C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs\migrations\005_email_cache.sql" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/migrations/005_email_cache.sql
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker exec -i jarvis-postgres psql -U jarvis -d jarvis < /home/jarvis-core/jarvis/migrations/005_email_cache.sql"
+```
+
+Expected output: `CREATE TABLE`, `CREATE INDEX`.
+
+- [ ] **Step 2: Add the DB helper and endpoint**
+
+In `Claude outputs/main.py`, add near the other DB helpers (after `get_latest_weather`):
+
+```python
+async def get_latest_emails(limit: int = 10):
+    return await db_query(
+        "SELECT sender, subject, received_at FROM email_cache ORDER BY received_at DESC LIMIT %s",
+        (limit,),
+        fetch="all",
+    )
+```
+
+Add the endpoint after `get_calendar_events`:
+
+```python
+@app.get("/api/v1/emails", dependencies=[Depends(require_admin_key)])
+async def get_cached_emails(limit: int = 10):
+    """Recently cached emails, populated by the n8n 'Neue E-Mails Cache' workflow"""
+    if not pg_pool:
+        raise HTTPException(status_code=503, detail="Database is not configured")
+
+    rows = await get_latest_emails(limit)
+    return {
+        "emails": [
+            {
+                "sender": row["sender"],
+                "subject": row["subject"],
+                "received_at": row["received_at"].isoformat(),
+            }
+            for row in rows
+        ]
+    }
+```
+
+- [ ] **Step 3: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"

+```
+
+Expected: log ends with `Application startup complete.`.
+
+```bash
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -H 'X-Admin-Key: $ADMIN_KEY' http://localhost:8000/api/v1/emails; echo"
+```
+
+Expected: `{"emails":[]}` (table is empty until Task 4's workflow runs).
+
+- [ ] **Step 4: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 3: Chat tool use (read + confirmed send)
+
+**Files:**
+- Modify: `Claude outputs/main.py` (tool definitions, `execute_tool`, system-prompt instructions)
+- Test: `Claude outputs/tests/test_chat_tools.py` (extend)
+
+**Interfaces:**
+- Consumes: `list_recent_emails`, `send_email` (Task 1).
+- Produces: two new entries in `CALENDAR_TOOLS` (kept in that list/constant name to avoid a second near-identical tools array — rename is out of scope) and matching branches in `execute_tool`.
+
+- [ ] **Step 1: Add the tool definitions**
+
+In `Claude outputs/main.py`, add two entries to the `CALENDAR_TOOLS` list (after `delete_calendar_event`'s closing `},`):
+
+```python
+    {
+        "name": "list_recent_emails",
+        "description": "List the most recent emails in the kontakt@mbo-tech-it.de inbox.",
+        "input_schema": {
+            "type": "object",
+            "properties": {
+                "limit": {"type": "integer", "description": "How many recent emails to list, e.g. 10"}
+            },
+            "required": ["limit"],
+        },
+    },
+    {
+        "name": "send_email",
+        "description": (
+            "Send an email from kontakt@mbo-tech-it.de. Only call this after "
+            "the user has explicitly confirmed recipient, subject and body "
+            "in the conversation."
+        ),
+        "input_schema": {
+            "type": "object",
+            "properties": {
+                "to": {"type": "string", "description": "Recipient email address"},
+                "subject": {"type": "string", "description": "Email subject"},
+                "body": {"type": "string", "description": "Plain text email body"},
+            },
+            "required": ["to", "subject", "body"],
+        },
+    },
+```
+
+- [ ] **Step 2: Extend the system-prompt instructions**
+
+In `Claude outputs/main.py`, change the `CALENDAR_ASSISTANT_INSTRUCTIONS` string (append to the existing text, keep everything before it unchanged):
+
+```python
+CALENDAR_ASSISTANT_INSTRUCTIONS = (
+    "Du hast Zugriff auf den Kalender 'FFW-Onza-Alle' ueber die Tools "
+    "list_calendar_events, create_calendar_event, update_calendar_event und "
+    "delete_calendar_event. create_calendar_event und update_calendar_event "
+    "kannst du direkt aufrufen, sobald du die noetigen Angaben hast - keine "
+    "Rueckfrage noetig. Bevor du delete_calendar_event aufrufst, frage den "
+    "Nutzer aber immer explizit im Klartext nach Bestaetigung und rufe das "
+    "Tool erst auf, nachdem der Nutzer im naechsten Chat-Beitrag zugestimmt "
+    "hat. Fuer update_calendar_event und delete_calendar_event brauchst du "
+    "die uid des Termins - ruf dafuer zuerst list_calendar_events auf, falls "
+    "du sie noch nicht aus dem Gespraech kennst.\n\n"
+    "Du hast ausserdem Zugriff auf das Postfach kontakt@mbo-tech-it.de ueber "
+    "die Tools list_recent_emails und send_email. list_recent_emails kannst "
+    "du direkt aufrufen. Bevor du send_email aufrufst, zeige dem Nutzer "
+    "Empfaenger, Betreff und Text zur Kontrolle und rufe das Tool erst auf, "
+    "nachdem der Nutzer im naechsten Chat-Beitrag zugestimmt hat - "
+    "kontakt@mbo-tech-it.de ist die offizielle Firmenadresse, eine "
+    "versendete Mail laesst sich nicht zurueckholen."
+)
+```
+
+- [ ] **Step 3: Wire the dispatcher**
+
+In `Claude outputs/main.py`, add to `execute_tool` (after the `delete_calendar_event` branch, before `raise ValueError`):
+
+```python
+    if name == "list_recent_emails":
+        emails = await list_recent_emails(tool_input.get("limit", 10))
+        return json.dumps(emails)
+    if name == "send_email":
+        result = await send_email(tool_input["to"], tool_input["subject"], tool_input["body"])
+        return json.dumps(result)
+```
+
+- [ ] **Step 4: Extend the chat-tools regression test**
+
+In `Claude outputs/tests/test_chat_tools.py`, add at the end of the file:
+
+```python
+@pytest.mark.asyncio
+async def test_run_chat_completion_lists_recent_emails():
+    first = MagicMock()
+    first.stop_reason = "tool_use"
+    first.content = [_tool_use_block("list_recent_emails", {"limit": 5}, "tool_1")]
+    first.usage = _usage(15, 6)
+
+    second = MagicMock()
+    second.stop_reason = "end_turn"
+    second.content = [_text_block("Du hast 5 neue Mails.")]
+    second.usage = _usage(20, 8)
+
+    main.claude_client = MagicMock()
+    main.claude_client.messages.create.side_effect = [first, second]
+
+    with patch.object(main, "list_recent_emails", new=AsyncMock(return_value=[])):
+        text, output_tokens, total_tokens = await main.run_chat_completion(
+            [{"role": "user", "content": "Was ist neu im Postfach?"}]
+        )
+
+    assert text == "Du hast 5 neue Mails."
+    assert output_tokens == 6 + 8
+    assert total_tokens == 15 + 6 + 20 + 8
+```
+
+- [ ] **Step 5: Run all backend tests**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"

+```
+
+Expected: all tests pass (should be 21 total: 17 previous + 3 email + 1 new chat-tools).
+
+- [ ] **Step 6: Deploy and verify against the live API**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS\Claude outputs"

+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose restart jarvis-api && sleep 10 && docker logs --tail 20 jarvis-api"
+```
+
+Expected: log ends with `Application startup complete.`.
+
+```bash
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -X POST http://localhost:8000/api/v1/chat -H 'Content-Type: application/json' -H 'X-Admin-Key: $ADMIN_KEY' -d '{\"message\": \"Was ist neu im Postfach kontakt@mbo-tech-it.de? Zeig die letzten 5 Mails.\"}'; echo"
+```
+
+Expected: a natural-language response listing real subjects/senders from the live inbox (proof the tool round-trip actually hit IMAP).
+
+Then test the confirmation gate:
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -X POST http://localhost:8000/api/v1/chat -H 'Content-Type: application/json' -H 'X-Admin-Key: $ADMIN_KEY' -d '{\"message\": \"Schick eine Testmail an kontakt@mbo-tech-it.de mit Betreff JARVIS Test und Text Hallo aus JARVIS.\"}'; echo"
+```
+
+Expected: JARVIS asks for confirmation, does NOT send yet (no `is_error` and no immediate "gesendet" claim). Confirm in a follow-up (`conversation_id` from the response) with `{"conversation_id": <id>, "message": "Ja, senden."}` and expect a real send confirmation - then check the inbox arrived (e.g. re-run `list_recent_emails` via chat, or check via the Task 1 IMAP test pattern).
+
+- [ ] **Step 7: Confirm files saved** (no git repo for this project — see Global Constraints)
+
+---
+
+### Task 4: n8n "Neue E-Mails Cache" workflow
+
+**Files:** none (n8n workflow lives in n8n's own database, not in this repo)
+
+**Interfaces:**
+- Consumes: n8n credentials "JARVIS Email IMAP" (id `4rU5KYIv1sKCJkAd`) and "JARVIS Postgres" (id `8b6g9X080UhxUgLv`), both already created.
+- Produces: rows in `email_cache` (Task 2's table), consumed by Task 5's widget.
+
+- [ ] **Step 1: Generate a fresh n8n API key**
+
+Via browser: log in at `https://n8n.jarvis.mbo-tech-it.de` (owner account `jonny@mbo-tech-it.de`), Settings → n8n API → Create API key, label "JARVIS Email Workflow Runtime", scope "All". Copy the value into a page-local JS variable immediately (it's only shown once) — same procedure as the weather workflow setup: paste into a visible input (e.g. the API-key-list search box) and read `.value` via `javascript_exec`, since the creation dialog's own field is CSS-truncated.
+
+- [ ] **Step 2: Create the workflow via the n8n REST API**
+
+Using `fetch` in the browser page context with `X-N8N-API-KEY` set to the key from Step 1 (POST to `/api/v1/workflows`):
+
+```json
+{
+  "name": "Neue E-Mails Cache",
+  "nodes": [
+    {
+      "id": "trigger1",
+      "name": "Email Trigger IMAP",
+      "type": "n8n-nodes-base.emailReadImap",
+      "typeVersion": 2,
+      "position": [240, 300],
+      "parameters": {
+        "mailbox": "INBOX",
+        "postProcessAction": "nothing",
+        "format": "simple",
+        "options": {}
+      },
+      "credentials": {
+        "imap": { "id": "4rU5KYIv1sKCJkAd", "name": "JARVIS Email IMAP" }
+      }
+    },
+    {
+      "id": "pg1",
+      "name": "Insert Email",
+      "type": "n8n-nodes-base.postgres",
+      "typeVersion": 2.5,
+      "position": [460, 300],
+      "parameters": {
+        "operation": "insert",
+        "schema": { "__rl": true, "value": "public", "mode": "list" },
+        "table": { "__rl": true, "value": "email_cache", "mode": "list" },
+        "columns": {
+          "mappingMode": "defineBelow",
+          "value": {
+            "sender": "={{ $json.from }}",
+            "subject": "={{ $json.subject }}",
+            "received_at": "={{ $json.date }}"
+          },
+          "matchingColumns": [],
+          "schema": []
+        }
+      },
+      "credentials": {
+        "postgres": { "id": "8b6g9X080UhxUgLv", "name": "JARVIS Postgres" }
+      }
+    }
+  ],
+  "connections": {
+    "Email Trigger IMAP": { "main": [[{ "node": "Insert Email", "type": "main", "index": 0 }]] }
+  },
+  "settings": { "executionOrder": "v1" }
+}
+```
+
+Note: the exact field name for the sender on the IMAP trigger's "simple" format output is unconfirmed (could be a plain string or an object like `{text, value}}` depending on the mail parser) — this is discovered and corrected in Step 4 below using a real test email, the same way the weather workflow's node parameters were verified against the live API before finalizing.
+
+- [ ] **Step 3: Activate the workflow**
+
+```
+POST /api/v1/workflows/<id>/activate
+```
+
+with the same API key.
+
+- [ ] **Step 4: Send a real test email and verify the cache row**
+
+Use the already-deployed and tested `send_email` (Task 3) to send a message to the inbox itself, so the new trigger has something to catch:
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+ADMIN_KEY=$(ssh $SSHOPTS jarvis-core@72.61.186.98 "grep API_KEY_ADMIN /home/jarvis-core/jarvis/.env" | cut -d= -f2-)
+ssh $SSHOPTS jarvis-core@72.61.186.98 "curl -s -X POST http://localhost:8000/api/v1/chat -H 'Content-Type: application/json' -H 'X-Admin-Key: $ADMIN_KEY' -d '{\"message\": \"Schick eine Testmail an kontakt@mbo-tech-it.de mit Betreff JARVIS n8n Cache Test und Text Test.\"}'; echo"
+```
+
+Confirm the send in a follow-up chat message (see Task 3 Step 6's confirmation pattern). Wait ~30-60s for the IMAP trigger to poll, then check:
+
+```bash
+ssh $SSHOPTS jarvis-core@72.61.186.98 "docker exec jarvis-postgres psql -U jarvis -d jarvis -c 'SELECT sender, subject, received_at FROM email_cache ORDER BY id DESC LIMIT 3;'"
+```
+
+Expected: a row with subject "JARVIS n8n Cache Test". If the `sender`/`subject`/`received_at` columns are empty or malformed, inspect the actual execution data in the n8n UI (Executions tab on the workflow) to see the real output shape from the "Email Trigger IMAP" node, and adjust the Postgres node's `columns.value` expressions accordingly (e.g. `$json.from.text` instead of `$json.from`) via a `PATCH /api/v1/workflows/<id>` call, then resend a test email to reverify.
+
+- [ ] **Step 5: Confirm the workflow is saved** (lives in n8n's own DB, not this repo — no file to save)
+
+---
+
+### Task 5: "Neue E-Mails" dashboard widget
+
+**Files:**
+- Create: `web/src/components/EmailWidget.tsx`
+- Modify: `web/src/components/Dashboard.tsx` (render it)
+
+**Interfaces:**
+- Consumes: `apiFetch` (existing), `GET /api/v1/emails` (Task 2).
+- Produces: `EmailWidget` default export, no props, rendered inside `Dashboard`.
+
+- [ ] **Step 1: Create the widget**
+
+Create `web/src/components/EmailWidget.tsx`:
+
+```tsx
+import { useEffect, useState } from "react";
+import { apiFetch } from "../api";
+
+type CachedEmail = { sender: string; subject: string; received_at: string };
+
+export default function EmailWidget() {
+  const [emails, setEmails] = useState<CachedEmail[] | null>(null);
+  const [error, setError] = useState<string | null>(null);
+
+  useEffect(() => {
+    async function load() {
+      try {
+        const response = await apiFetch("/api/v1/emails?limit=5");
+        if (!response.ok) {
+          setError("Postfach-Cache nicht verfuegbar");
+          return;
+        }
+        const data = await response.json();
+        setEmails(data.emails);
+      } catch {
+        setError("Postfach-Cache nicht verfuegbar");
+      }
+    }
+    load();
+  }, []);
+
+  return (
+    <div className="email-widget">
+      <h3>Neue E-Mails</h3>
+      {error && <p className="error">{error}</p>}
+      {emails && emails.length === 0 && <p>Noch keine gecachten E-Mails.</p>}
+      {emails && emails.length > 0 && (
+        <ul>
+          {emails.map((e, i) => (
+            <li key={i}>
+              {`${new Date(e.received_at).toLocaleDateString("de-DE")}: ${e.sender} \u2013 ${e.subject}`}
+            </li>
+          ))}
+        </ul>
+      )}
+    </div>
+  );
+}
+```
+
+- [ ] **Step 2: Render it in the Dashboard**
+
+In `web/src/components/Dashboard.tsx`, add the import next to `CalendarWidget`'s:
+
+```tsx
+import EmailWidget from "./EmailWidget";
+```
+
+Add `<EmailWidget />` right after `<CalendarWidget />`.
+
+- [ ] **Step 3: Verify the build works**
+
+```bash
+cd "C:\Users\Jonny\Projekte\Claude\JARVIS\web"
+npm run build
+```
+
+Expected: exits 0.
+
+- [ ] **Step 4: Deploy**
+
+```bash
+SSHOPTS="-F /dev/null -o IdentitiesOnly=yes -i /c/Users/Jonny/.ssh/jarvis_core_key"
+OUT="C:\Users\Jonny\Projekte\Claude\JARVIS"
+scp $SSHOPTS -r "$OUT\web\src" jarvis-core@72.61.186.98:/home/jarvis-core/jarvis/web/
+ssh $SSHOPTS jarvis-core@72.61.186.98 "cd /home/jarvis-core/jarvis && docker compose build jarvis-web && docker compose up -d jarvis-web"
+```
+
+- [ ] **Step 5: End-to-end browser verification**
+
+Using the claude-in-chrome browser tools: log in at `https://jarvis.mbo-tech-it.de` (append a cache-busting query param like `?nocache=1` on first load after deploy if the page looks stale, per the known nginx/browser-cache behavior documented in `JARVIS_HANDOFF.md`), open Dashboard, confirm "Neue E-Mails" lists the test email(s) from Task 4.
+
+- [ ] **Step 6: Confirm files saved** (no git repo for this project — see Global Constraints)

+# JARVIS Knowledge Base (Phase 3) - Design
+
+**Datum:** 2026-09-12
+**Status:** Approved, bereit fuer Implementierungsplan
+
+## Kontext
+
+Phase 2 (Claude-Chat-Integration, Postgres-Persistenz, Health-Checks) ist live
+auf dem VPS (72.61.186.98). Die JARVIS-API hat bereits Platzhalter-Endpunkte
+fuer eine Knowledge Base (`POST/GET /api/v1/documents`), die aktuell nur
+TODO-Stubs sind. Diese Spec beschreibt die echte Implementierung.
+
+Die urspruengliche Architektur (siehe `JARVIS_HANDOFF.md`) sah Milvus als
+Vector-DB vor. Das dafuer vorbereitete `docker-compose.yml` referenziert
+`milvusdb/milvus:v0.4.0`, ein nicht existierendes Image, und ein veraltetes
+Config-Format (nur etcd, kein MinIO) das mit modernem Milvus-Standalone nicht
+kompatibel ist. Statt das nachzubauen, wird stattdessen `pgvector` in der
+bereits laufenden Postgres-Instanz verwendet - siehe Entscheidung unten.
+
+## Entscheidung: pgvector statt Milvus
+
+| | pgvector (gewaehlt) | Milvus |
+|---|---|---|
+| Neue Container | keine | etcd, minio, milvus (3) |
+| Betriebsaufwand | keiner (nutzt laufenden Postgres) | hoch (3 zusaetzliche Services) |
+| Konsistenz | Transaktional mit `documents`/`conversations` | separates System, kein 2PC |
+| Skalierung | ausreichend bis mehrere 100k Chunks | besser bei Millionen Vektoren |
+
+Fuer eine Business-Knowledge-Base in diesem Umfang ist pgvector die
+pragmatischere Wahl (YAGNI). Milvus bleibt als unbenutzter Platzhalter im
+`docker-compose.yml` dokumentiert, falls spaetere Skalierung es noetig macht.
+
+## Embeddings: Ollama (`nomic-embed-text`)
+
+Anthropic bietet keine Embedding-API an. Da Ollama bereits im Stack laeuft,
+wird lokal embedded statt ueber einen weiteren externen Anbieter (OpenAI/
+Voyage) mit eigenem Key und laufenden Kosten:
+
+- Modell: `nomic-embed-text` (768 Dimensionen), einmalig per
+  `docker exec jarvis-ollama ollama pull nomic-embed-text` zu laden.
+- Aufruf ueber Ollama's `/api/embeddings` HTTP-Endpoint (aiohttp, analog zum
+  bestehenden Health-Check-Pattern in `main.py`).
+
+## Datenmodell
+
+Neue Tabelle `document_chunks`:
+
+```sql
+CREATE EXTENSION IF NOT EXISTS vector;
+
+CREATE TABLE document_chunks (
+    id SERIAL PRIMARY KEY,
+    document_id INTEGER NOT NULL REFERENCES documents(id) ON DELETE CASCADE,
+    chunk_index INTEGER NOT NULL,
+    content TEXT NOT NULL,
+    embedding vector(768) NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_document_chunks_document_id ON document_chunks(document_id);
+CREATE INDEX idx_document_chunks_embedding ON document_chunks
+    USING ivfflat (embedding vector_cosine_ops) WITH (lists = 100);
+```
+
+Die bestehende `documents`-Tabelle speichert weiterhin Titel/Volltext/
+Metadaten; `embedding_id` (bisher ungenutzt) bleibt vorerst unangetastet, da
+die Beziehung jetzt ueber `document_chunks.document_id` laeuft.
+
+## Datenfluss
+
+**Upload (`POST /api/v1/documents`):**
+1. Dokument-Zeile in `documents` anlegen (title, content, document_type).
+2. Text in Chunks teilen: ~1000 Zeichen, 100 Zeichen Overlap (einfaches
+   Character-Chunking, kein Tokenizer noetig - ausreichend fuer Business-
+   Dokumente in diesem Umfang).
+3. Pro Chunk: Embedding via Ollama holen, Zeile in `document_chunks`
+   einfuegen.
+4. Response: `document_id`, Anzahl Chunks, Status `indexed`.
+
+Passiert synchron im Request (kein Background-Queue-Mechanismus) - bei den
+erwarteten Dokumentgroessen (Business-FAQs, Anleitungen) unkritisch fuer die
+Latenz. Wird das spaeter zum Problem, ist ein Queue-basierter Ansatz ein
+separates Follow-up.
+
+**Suche (`GET /api/v1/documents?query=...`):**
+1. Suchanfrage ueber Ollama embedden.
+2. `document_chunks` per Cosine-Distanz (`<=>`-Operator) sortieren, Top N
+   (Parameter `limit`, Default 10).
+3. Pro Treffer: Chunk-Inhalt, Distanz-Score, zugehoeriger Dokumenttitel.
+
+## Fehlerbehandlung
+
+- Ollama nicht erreichbar oder Modell nicht gepullt -> `503` mit klarer
+  Fehlermeldung (analog zum bestehenden `CLAUDE_API_KEY`-Check in `chat()`).
+- Leerer/zu kurzer Query-String -> `422` (Pydantic-Validierung).
+- Dokument ohne Inhalt -> `422`.
+
+## Testing
+
+- Unit-Test fuer die Chunking-Funktion (Grenzfaelle: leerer Text, Text
+  kuerzer als Chunk-Groesse, Text mit exaktem Vielfachen der Chunk-Groesse).
+- Manueller End-to-End-Test nach Deployment: Dokument hochladen, danach mit
+  einer thematisch passenden Frage suchen und pruefen, dass der richtige
+  Chunk als Top-Treffer kommt (analog zum manuellen Chat-Test aus Phase 2,
+  da auf dem VPS kein automatisierter Test-Runner etabliert ist).
+
+## Nachtrag (gefunden bei der Umsetzung, 2026-09-12)
+
+Der in diesem Dokument spezifizierte `ivfflat`-Index auf `document_chunks.embedding`
+hat bei sehr wenig Daten (getestet mit 1 Zeile) eine so geringe Recall-Rate,
+dass `ORDER BY ... LIMIT` Anfragen **keine** Treffer zurückgeben (bestätigt:
+funktioniert erst mit `SET ivfflat.probes = 10`). Genau das kündigt Postgres
+schon beim Anlegen des Index an ("This will cause low recall... Drop the
+index until the table has more data").
+
+**Ruling:** Index per Migration `003_drop_low_data_ivfflat_index.sql` wieder
+entfernt. Ein Sequential Scan ist bei der aktuellen Datenmenge korrekt und
+schnell genug. Sobald `document_chunks` eine relevante Groessenordnung an
+Zeilen hat (Richtwert pgvector-Doku: `lists ~= sqrt(row_count)`), sollte der
+Index mit einem zur dann aktuellen Zeilenzahl passenden `lists`-Wert neu
+angelegt werden - das ist ein eigenes Follow-up, keine sofortige Aufgabe.
+
+## Out of Scope (bewusst nicht Teil dieser Phase)
+
+- RAG-Integration in den Chat-Endpoint (automatisches Anreichern von
+  Claude-Antworten mit Suchtreffern) - eigenes Follow-up.
+- Re-Embedding bei Dokument-Update/-Loeschung ausserhalb von `ON DELETE
+  CASCADE`.
+- Zugriffskontrolle pro Nutzer (kein Auth-System vorhanden, siehe Phase 3
+  in `JARVIS_HANDOFF.md`).

+# JARVIS Weather Widget (Phase 4a) - Design
+
+**Datum:** 2026-09-12
+**Status:** Approved, bereit fuer Implementierungsplan
+
+## Kontext
+
+Phase 3b (Web-Frontend mit Chat + Dashboard) ist live. `n8n` laeuft bereits im
+Stack seit Phase 2/3, wurde aber noch nie konfiguriert (kein Owner-Account,
+keine Workflows). Diese Spec macht n8n zum ersten Mal produktiv nutzbar: ein
+Workflow holt periodisch das Wetter fuer Crailsheim (Firmenstandort laut
+`JARVIS_HANDOFF.md`) und das Frontend zeigt es oben rechts in der Nav-Leiste
+an.
+
+## Datenfluss
+
+```
+n8n (Schedule-Trigger, alle 30 Min)
+  -> HTTP Request: Open-Meteo API (kein API-Key noetig)
+  -> Code-Node: WMO-Wettercode -> deutscher Text
+  -> Postgres-Node: INSERT INTO weather_cache
+
+JARVIS-API: GET /api/v1/weather liest die neueste Zeile aus weather_cache
+
+Frontend: WeatherWidget faengt beim Laden + alle 5 Min neu ab
+```
+
+## Wetterquelle: Open-Meteo
+
+Kein API-Key noetig (kostenlos, keine Registrierung). Endpoint:
+
+```
+https://api.open-meteo.com/v1/forecast?latitude=49.1372&longitude=10.0674&current=temperature_2m,weather_code&timezone=Europe%2FBerlin
+```
+
+Antwortformat (Auszug):
+```json
+{
+  "current": {
+    "time": "2026-09-12T16:00",
+    "temperature_2m": 18.4,
+    "weather_code": 3
+  }
+}
+```
+
+WMO-Wettercode-Mapping (Open-Meteo-Standard, Teilmenge fuer die haeufigsten
+Faelle - vollstaendige Tabelle im Code-Node):
+
+| Code | Text |
+|------|------|
+| 0 | Klarer Himmel |
+| 1-2 | Ueberwiegend klar |
+| 3 | Bewoelkt |
+| 45, 48 | Nebel |
+| 51-57 | Nieselregen |
+| 61-67 | Regen |
+| 71-77 | Schnee |
+| 80-82 | Regenschauer |
+| 95-99 | Gewitter |
+| (sonst) | Unbekannt |
+
+## Datenmodell
+
+Neue Tabelle `weather_cache`:
+
+```sql
+CREATE TABLE weather_cache (
+    id SERIAL PRIMARY KEY,
+    location VARCHAR(100) NOT NULL,
+    temperature_c NUMERIC NOT NULL,
+    condition_code INTEGER NOT NULL,
+    condition_text VARCHAR(100) NOT NULL,
+    fetched_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_weather_cache_fetched_at ON weather_cache(fetched_at);
+```
+
+Jeder n8n-Lauf fuegt eine neue Zeile ein (kein Update/Upsert - einfacher,
+und die Tabelle bleibt klein bei 30-Minuten-Intervall; alte Zeilen aufraeumen
+ist ein spaeteres Follow-up, kein akutes Problem bei diesem Datenvolumen).
+
+## n8n-Workflow: "Wetter Crailsheim"
+
+n8n wurde bisher nie initialisiert (kein Owner-Account, kein API-Key fuer die
+n8n-REST-API). Einmaliger Setup-Schritt (per Browser, da n8n das beim ersten
+Aufruf erzwingt): Owner-Account anlegen, dann unter Settings -> API einen
+API-Key generieren. Danach wird der Workflow per n8n-REST-API (`POST
+/rest/workflows` bzw. `/api/v1/workflows` je nach n8n-Version, siehe Plan)
+als JSON-Definition angelegt und aktiviert - kein manuelles Zusammenklicken
+der Nodes.
+
+Workflow-Nodes:
+1. **Schedule Trigger**: Intervall 30 Minuten.
+2. **HTTP Request**: GET auf die Open-Meteo-URL oben.
+3. **Code** (JavaScript): mapped `weather_code` auf `condition_text` (Tabelle
+   oben), reicht `temperature_2m`, `weather_code` und `condition_text` weiter.
+4. **Postgres**: `INSERT INTO weather_cache (location, temperature_c,
+   condition_code, condition_text) VALUES ('Crailsheim', ..., ..., ...)`.
+   n8n's Postgres-Credential zeigt auf dieselbe `jarvis`-Datenbank, die die
+   API auch nutzt (gleicher Host/User/Passwort wie `DATABASE_URL` der API,
+   siehe `.env`).
+
+## Backend: `GET /api/v1/weather`
+
+Neuer Endpoint in `main.py`, durch `require_admin_key` geschuetzt (wie alle
+anderen `/api/v1/*`-Routen ausser `/health`):
+
+```json
+{
+  "location": "Crailsheim",
+  "temperature_c": 18.4,
+  "condition_text": "Bewoelkt",
+  "fetched_at": "2026-09-12T16:00:03.123456"
+}
+```
+
+Wenn `weather_cache` leer ist (Workflow lief noch nicht): `503` mit
+Fehlermeldung "Weather data not available yet" - kein stiller Platzhalter,
+das Frontend zeigt das dann sichtbar als Fehler statt falscher Daten.
+
+## Frontend: `WeatherWidget`
+
+Kleine Komponente, in der Nav-Leiste rechtsbuendig (per CSS `margin-left:
+auto` auf dem Widget-Container, bestehende Nav-Buttons bleiben linksbuendig).
+Sichtbar in beiden Ansichten (Chat + Dashboard), da die Nav-Leiste immer
+gerendert wird.
+
+- Beim Mount: `GET /api/v1/weather` laden.
+- Danach alle 5 Minuten neu laden (`setInterval`, aufgeraeumt in
+  `useEffect`-Cleanup) - haeufiger als noetig waere reine Verschwendung,
+  seltener als der 30-Minuten-Workflow waere unnoetig zurueckhaltend; 5
+  Minuten ist ein vernuenftiger Mittelweg fuer eine UI-Anzeige.
+- Anzeige: `18.4°C · Bewoelkt`. Bei Fehler (503 o.ae.): unauffaellige
+  Kurzmeldung statt der Wetteranzeige (kein Popup/Alert), da es sich um ein
+  Nice-to-have-Widget handelt, keine kritische Funktion.
+
+## Fehlerbehandlung
+
+- Open-Meteo nicht erreichbar: n8n-Workflow-Lauf schlaegt fehl, naechster
+  Lauf in 30 Minuten versucht es erneut. Kein Retry innerhalb eines Laufs
+  (YAGNI - Schedule-Trigger uebernimmt das ohnehin).
+- `weather_cache` leer: Backend liefert `503`, Frontend zeigt Kurzmeldung.
+- n8n/Postgres-Verbindung fehlerhaft: sichtbar im n8n-Execution-Log (manuell
+  pruefbar in der n8n-UI), keine gesonderte Behandlung noetig fuer dieses
+  Nice-to-have-Feature.
+
+## Testing
+
+- Backend: Unit-Test fuer `GET /api/v1/weather` - leere Tabelle -> 503,
+  vorhandene Zeile -> korrektes JSON (mit einer eingefuegten Testzeile via
+  `TestClient` + einer echten Test-Postgres-Instanz ist hier zu viel Aufwand
+  fuer dieses kleine Feature; stattdessen wird die Query-Logik direkt
+  getestet, indem die DB-Helper-Funktion mit einer gemockten `db_query`
+  aufgerufen wird - siehe Plan fuer die konkrete Test-Strategie).
+- Frontend: kein gesonderter Unit-Test (das Widget ist eine einfache
+  Fetch-und-Anzeige-Komponente, gleiches Muster wie `Dashboard.tsx`, das
+  auch keinen Unit-Test hat) - Build-Check (`npm run build`) reicht,
+  passend zum bisherigen Muster in diesem Projekt.
+- Manueller End-to-End-Test nach Deployment: n8n-Workflow einmal manuell
+  ausloesen (n8n-UI "Execute Workflow" oder Warten auf den ersten
+  Schedule-Lauf), pruefen dass `weather_cache` eine Zeile hat, `GET
+  /api/v1/weather` testen, Widget im Browser sehen.
+
+## Out of Scope (bewusst nicht Teil dieser Phase)
+
+- Mehrere Standorte / nutzerkonfigurierbarer Standort.
+- Wettervorhersage (nur aktuelles Wetter, kein Forecast-Display).
+- Aufraeumen alter `weather_cache`-Zeilen (Retention-Policy) - spaeteres
+  Follow-up, kein Problem bei aktuellem Datenvolumen.
+- Wetter-Icons/Grafiken - nur Text.

+# JARVIS Web Frontend (Phase 3b) - Design
+
+**Datum:** 2026-09-12
+**Status:** Approved, bereit fuer Implementierungsplan
+
+## Kontext
+
+Phase 2 (Claude-Chat) und Phase 3a (Knowledge Base via pgvector) sind live auf
+`https://jarvis.mbo-tech-it.de` (API) mit Traefik-Routing ueber den bereits
+vorhandenen, geteilten Reverse-Proxy des VPS. `JARVIS_HANDOFF.md` listet
+Phase 3 "Frontend" mit vier Punkten (React/Vue Web UI, Authentication UI,
+Chat Interface, Dashboard) - das wurde bewusst aufgeteilt: eine
+"Authentication UI" braucht ein Auth-System, das serverseitig nicht
+existiert (kein Login/JWT-Flow). Diese Spec deckt Chat + Dashboard als eine
+gemeinsame Web-App ab; ein vollwertiges Auth-System bleibt ein separates
+Follow-up.
+
+## Sicherheitsproblem, das diese Phase mitloest
+
+`/api/v1/chat` hat aktuell keinerlei Zugriffsschutz und CORS steht auf `*`.
+Eine oeffentlich erreichbare Chat-UI unter einer bekannten Domain waere ohne
+Schutz von jedem nutzbar, der die Domain findet, und wuerde Claude-API-
+Guthaben verbrauchen. Diese Spec fuehrt deshalb einen einfachen
+Shared-Secret-Schutz ein (kein vollwertiges User-System - das ist bewusst
+YAGNI fuer den aktuellen Umfang, siehe Out of Scope).
+
+## Domain-Aufteilung
+
+- `jarvis.mbo-tech-it.de` -> Web-Frontend (neu, dieser Service)
+- `api.jarvis.mbo-tech-it.de` -> JARVIS-API (Umzug von der Hauptdomain)
+
+Kein neuer DNS-Eintrag noetig: der Wildcard-Record `*.jarvis.mbo-tech-it.de`
+(siehe Traefik-Integration in `JARVIS_HANDOFF.md`) deckt `api.jarvis...`
+bereits ab.
+
+## Zugriffsschutz: Shared Secret statt vollwertiges Auth-System
+
+Wiederverwendung des bereits in `.env` vorhandenen `API_KEY_ADMIN` (kein
+neues Secret noetig). Ablauf:
+
+1. Neue FastAPI-Dependency `require_admin_key` prueft den Header
+   `X-Admin-Key` gegen `API_KEY_ADMIN`. Fehlt der Header oder stimmt der Wert
+   nicht -> `401 Unauthorized`.
+2. Angewendet auf: `POST /api/v1/chat`, `GET /api/v1/conversations/{id}`,
+   `POST/GET /api/v1/documents`, `POST/GET /api/v1/tasks`,
+   `POST /api/v1/workflows/trigger`, `GET /api/v1/admin/stats`,
+   `GET /api/v1/admin/health/detailed`.
+3. **Nicht** geschuetzt: `GET /health` (wird fuer einfaches Monitoring/
+   Uptime-Checks offen gehalten - liefert ohnehin keine sensiblen Daten).
+4. CORS wird von `allow_origins=["*"]` auf
+   `allow_origins=["https://jarvis.mbo-tech-it.de"]` eingeschraenkt, da wir
+   an dieser Stelle ohnehin an der Zugriffskontrolle arbeiten.
+
+Im Frontend: Login-Screen mit einem Passwort-Feld. Eingabe wird nicht
+client-seitig validiert, sondern per Testaufruf gegen
+`GET /api/v1/admin/stats` mit dem eingegebenen Wert als `X-Admin-Key`
+geprueft. Bei `200` wird der Wert in `localStorage` (Key
+`jarvis_admin_key`) gespeichert und die Hauptansicht angezeigt. Bei `401`
+Fehlermeldung im Login-Screen. Jeder weitere API-Call haengt den
+gespeicherten Wert als `X-Admin-Key`-Header an; ein `401` auf irgendeinem
+Call loescht den `localStorage`-Eintrag und zeigt wieder den Login-Screen.
+
+## Frontend-Architektur
+
+React + Vite, kein zusaetzliches Routing (nur zwei Views, ein einfacher
+State-Switch reicht - YAGNI). Struktur:
+
+```
+web/
+  src/
+    main.tsx              # Einstiegspunkt
+    App.tsx                # Login-Gate + Nav zwischen Chat/Dashboard
+    api.ts                 # fetch-Wrapper: haengt X-Admin-Key an, wirft
+                            # bei 401 einen speziellen Fehler, den App.tsx
+                            # abfaengt um zurueck zum Login zu wechseln
+    components/
+      Login.tsx             # Passwort-Feld, Testaufruf, Fehleranzeige
+      Chat.tsx              # Nachrichtenliste + Eingabefeld
+      Dashboard.tsx         # Stats-Karten + Health-Tabelle
+  index.html
+  package.json
+  vite.config.ts
+  Dockerfile              # Multi-Stage: node:20-slim build -> nginx:alpine serve
+  nginx.conf              # SPA-Fallback (alle Routen -> index.html)
+```
+
+`VITE_API_URL` (Build-Zeit-Env-Var) zeigt auf
+`https://api.jarvis.mbo-tech-it.de`.
+
+### Chat (`Chat.tsx`)
+
+- Lokaler State: `messages: {role, content}[]`, `conversationId: number | null`.
+- Eingabefeld + Senden-Button (auch Enter-Taste). Waehrend eine Antwort
+  aussteht: Eingabe gesperrt, Ladeindikator.
+- Sendet `POST /api/v1/chat` mit `{conversation_id: conversationId, message}`.
+  Antwort haengt User- und Assistant-Nachricht an `messages` an, setzt
+  `conversationId` aus der Response.
+- Fehler (z.B. 503 wegen fehlendem Claude-Guthaben) werden als Systemzeile
+  im Chatverlauf angezeigt, nicht stillschweigend verschluckt.
+
+### Dashboard (`Dashboard.tsx`)
+
+- Beim Mount: `GET /api/v1/admin/stats` und
+  `GET /api/v1/admin/health/detailed` parallel laden.
+- Stats als drei Zahlen-Karten (Conversations/Tasks/Documents).
+- Health als Tabelle: Service-Name, Status (ok/error als farbiges Badge),
+  Response-Time. Manueller "Aktualisieren"-Button (kein Auto-Polling - fuer
+  den aktuellen Umfang unnoetig, YAGNI).
+
+## Fehlerbehandlung
+
+- Netzwerkfehler (API nicht erreichbar): Inline-Fehlermeldung statt
+  unbehandeltem Absturz, sowohl in Chat als auch Dashboard.
+- 401 an beliebiger Stelle: zentral in `api.ts` behandelt (siehe oben),
+  nicht in jeder Komponente einzeln.
+- Leere Eingabe im Chat: Senden-Button deaktiviert, kein Request.
+
+## Testing
+
+- Backend: Unit-Test fuer `require_admin_key` (gueltiger Key -> durchgelassen,
+  fehlender Key -> 401, falscher Key -> 401) mit FastAPI `TestClient`.
+- Frontend: Unit-Test (Vitest) fuer `api.ts` - prueft, dass der
+  `X-Admin-Key`-Header aus `localStorage` gesetzt wird und dass eine
+  401-Antwort den `localStorage`-Eintrag entfernt.
+- Manueller End-to-End-Test im Browser nach Deployment: Login mit falschem
+  Passwort (Fehler sichtbar), Login mit richtigem Passwort, eine
+  Chat-Nachricht senden und Antwort sehen, zum Dashboard wechseln und Stats/
+  Health sehen (passend zum bisherigen Muster in diesem Projekt - kein
+  automatisierter Browser-Test-Runner vorhanden).
+
+## Out of Scope (bewusst nicht Teil dieser Phase)
+
+- Vollwertiges User-/Auth-System (Login pro Benutzer, JWT, Rollen) - das ist
+  weiterhin offener Punkt in Phase 3 von `JARVIS_HANDOFF.md`, unabhaengig von
+  dieser Spec.
+- Tasks/Documents-Verwaltung im Frontend (Erstellen/Anzeigen ueber die UI) -
+  nur Chat + Dashboard in dieser Phase.
+- Auto-Refresh/Live-Updates im Dashboard.
+- Mobile-optimiertes Layout ueber einfache Responsivitaet hinaus.

+# JARVIS Nextcloud-Kalender-Integration (Phase 4c) - Design
+
+**Datum:** 2026-09-13
+**Status:** Approved, bereit fuer Implementierungsplan
+
+## Kontext
+
+Naechste Erweiterung nach dem Wetter-Widget: Zugriff auf einen bestehenden
+Nextcloud-Kalender ("FFW-Onza-Alle", ein geteilter Organisations-Kalender der
+Freiwilligen Feuerwehr Onza) via CalDAV. JARVIS soll Termine anzeigen, im
+Chat abfragbar machen und - nach Bestaetigung im Chat - neue Termine anlegen
+koennen.
+
+**Verbindung verifiziert (13.09.2026):**
+- CalDAV-URL: `https://cloud.ffw-onza.de/remote.php/dav/calendars/jonny/ffw-onza-alle/`
+- Auth: HTTP Basic mit Nextcloud-App-Passwort (User `jonny`)
+- Python-Library `caldav` (+ `icalendar` als Abhaengigkeit) liest und
+  schreibt erfolgreich gegen diesen Kalender (Testtermin angelegt und wieder
+  geloescht)
+- Kalender-Timezone: Europe/Berlin
+- Enthaelt sowohl Termine mit Uhrzeit (`dtstart` als `datetime`) als auch
+  ganztaegige Termine (`dtstart` als `date` ohne Uhrzeit, z.B. "Volksfestwache")
+
+## Sicherheit: Schreibzugriff nur nach Bestaetigung
+
+Der Kalender ist ein geteilter Organisations-Kalender, kein privater. Direkte,
+unbestaetigte Termin-Erstellung durch ein LLM (Halluzinationsrisiko) waere in
+einem geteilten Kalender riskanter als in einem privaten. Deshalb:
+
+- Der Chat-System-Prompt weist Claude explizit an, vor jedem Aufruf von
+  `create_calendar_event` im Klartext nachzufragen ("Soll ich den Termin XY
+  am [Datum] anlegen?") und das Tool erst aufzurufen, nachdem der Nutzer im
+  naechsten Chat-Turn zugestimmt hat.
+- Das ist Prompt-Steuerung, kein hartes technisches Gate (kein separates
+  Freigabe-UI) - Standardmuster fuer LLM-Tool-Use mit Human-in-the-loop bei
+  diesem Umfang. Ein hartes Gate (z.B. ein Bestaetigungs-Endpoint) waere fuer
+  diese Phase Overengineering (YAGNI) und ist ein moegliches Follow-up, falls
+  sich in der Praxis zeigt, dass die Prompt-Steuerung nicht ausreicht.
+
+## Architektur
+
+Neues Modul-internes CalDAV-Setup in `main.py` (kein eigenes File noetig bei
+diesem Umfang - passt zur bestehenden Ein-Datei-Struktur des Projekts):
+
+```
+NEXTCLOUD_CALDAV_URL = os.getenv("NEXTCLOUD_CALDAV_URL")
+NEXTCLOUD_USER = os.getenv("NEXTCLOUD_USER")
+NEXTCLOUD_APP_PASSWORD = os.getenv("NEXTCLOUD_APP_PASSWORD")
+```
+
+Zwei synchrone Helper-Funktionen (die `caldav`-Library ist nicht async-nativ,
+daher ueber `asyncio.to_thread` aufgerufen - gleiches Muster wie die
+bestehenden Postgres-Helper via `db_query`):
+
+- `list_upcoming_events(days_ahead: int) -> list[dict]` - liest Termine der
+  naechsten N Tage, sortiert nach Start, gibt `{summary, start, end,
+  description, all_day}` pro Termin zurueck (Datumswerte als ISO-Strings).
+- `create_event(summary: str, start: str, end: str, description: str = "") ->
+  dict` - legt einen neuen Termin an (ISO-8601-Datums-/Zeitstrings als Input,
+  vom Aufrufer bzw. von Claude im Tool-Call geliefert), gibt die
+  gespeicherten Werte zurueck.
+
+## Backend-Endpoint (fuer das Dashboard-Widget)
+
+`GET /api/v1/calendar/events?days=14` (geschuetzt wie alle anderen Routen)
+ruft `list_upcoming_events` auf und gibt `{"events": [...]}` zurueck. Bei
+Verbindungs-/Auth-Fehler zu Nextcloud: `503` mit Fehlermeldung statt
+stillem leerem Array - ein leeres Array waere nicht von "wirklich keine
+Termine" unterscheidbar.
+
+## Chat-Integration: Claude Tool Use
+
+`/api/v1/chat` bekommt einen `tools`-Parameter mit zwei Tool-Definitionen:
+
+1. `list_calendar_events` - Parameter `days_ahead` (Ganzzahl). Ruft
+   `list_upcoming_events` auf.
+2. `create_calendar_event` - Parameter `summary`, `start` (ISO-8601),
+   `end` (ISO-8601), optional `description`. Ruft `create_event` auf.
+
+Ablauf pro Chat-Request: Claude wird mit den Tools aufgerufen. Antwortet
+Claude mit einem `tool_use`-Block, fuehrt das Backend die entsprechende
+Python-Funktion aus, haengt das Ergebnis als `tool_result` an die
+Konversation an und ruft Claude ein zweites Mal auf, um die finale,
+natuerlichsprachige Antwort zu bekommen (ein Tool-Call-Zyklus reicht fuer die
+hier vorgesehenen Anwendungsfaelle - keine mehrstufige Tool-Verkettung noetig,
+YAGNI). Der System-Prompt wird um die Bestaetigungs-Regel (siehe oben)
+ergaenzt.
+
+Die vom Tool-Use erzeugten Zwischennachrichten (der `tool_use`- und
+`tool_result`-Turn) werden **nicht** in der `messages`-Tabelle gespeichert -
+nur die sichtbare finale Nutzer-/Assistant-Nachricht, wie bisher. Das haelt
+die Persistenz-Logik unveraendert und die Chat-Historie fuer das Frontend
+weiterhin einfach (reine user/assistant-Paare).
+
+## Frontend: "Nächste Termine"-Widget im Dashboard
+
+Neue Sektion in `Dashboard.tsx` (oder eigene Komponente `CalendarWidget`,
+analog zu `WeatherWidget`): laedt `GET /api/v1/calendar/events?days=14` und
+zeigt eine einfache Liste (Datum + Uhrzeit falls vorhanden + Titel). Kein
+eigenes Erstellen/Bearbeiten im Dashboard (das laeuft ueber den Chat) - YAGNI
+fuer diese Phase.
+
+## Fehlerbehandlung
+
+- Nextcloud nicht erreichbar/Auth ungueltig: `list_upcoming_events`/
+  `create_event` werfen eine Exception mit klarer Meldung. Im
+  Dashboard-Endpoint wird daraus ein `503`. Im Chat-Tool-Use-Pfad wird die
+  Fehlermeldung als `tool_result` mit `is_error: true` an Claude
+  zurueckgegeben, das sie dann verstaendlich im Chat formuliert (kein roher
+  Stacktrace fuer den Nutzer).
+- Ganztaegige Termine (kein `dtstart`-Zeitanteil): werden mit `all_day: true`
+  markiert, Frontend zeigt dafuer nur das Datum ohne Uhrzeit.
+
+## Testing
+
+- Backend: Unit-Tests fuer `list_upcoming_events` und `create_event` mit
+  gemocktem `caldav.DAVClient` (keine echten Netzwerkaufrufe im Test).
+- Manueller End-to-End-Test nach Deployment: Dashboard-Widget zeigt echte
+  Termine (bereits verifiziert: 11 vorhandene Termine im Kalender), im Chat
+  nach "was steht diese Woche an?" fragen, dann testweise einen Termin
+  anlegen lassen inkl. Bestaetigungs-Nachfrage - danach den Test-Termin
+  wieder aus dem echten Kalender loeschen (manuell oder per Skript), damit
+  der Organisations-Kalender sauber bleibt.
+
+## Out of Scope (bewusst nicht Teil dieser Phase)
+
+- Bearbeiten/Loeschen bestehender Termine ueber Chat oder Dashboard.
+- Mehrere Kalender/Kalenderauswahl (nur der eine angegebene Kalender).
+- Wiederkehrende Termine anlegen (nur einmalige Termine ueber
+  `create_calendar_event`).
+- Hartes technisches Freigabe-Gate fuer Termin-Erstellung (siehe
+  "Sicherheit" oben) - Prompt-Steuerung reicht fuer den Start.

+# JARVIS E-Mail-Integration (Phase 4f) - Design
+
+**Datum:** 2026-09-13
+**Status:** Approved, bereit fuer Implementierungsplan
+
+## Kontext
+
+Naechste Integration nach Wetter (n8n-Cache) und Kalender (direktes CalDAV
+Tool-Use): Zugriff auf das Postfach `kontakt@mbo-tech-it.de`. JARVIS soll
+E-Mails lesen/zusammenfassen koennen (Chat, live) und - nach Bestaetigung -
+E-Mails versenden koennen, plus ein Dashboard-Widget fuer neu eingegangene
+Mails (n8n-Cache, wie beim Wetter).
+
+**Zugangsdaten verifiziert (13.09.2026):**
+- IMAP: `mx2f35.netcup.net:143`, STARTTLS, User `kontakt@mbo-tech-it.de`
+  (Login + INBOX-Zugriff erfolgreich getestet, 14 vorhandene Nachrichten)
+- SMTP: `mx2f35.netcup.net:465`, implizites SSL/TLS, gleiche Zugangsdaten
+  (Login erfolgreich getestet, kein Test-Versand)
+- Passwort ist woertlich `E%21gq10i` (kein URL-encodetes `!` - beide
+  Interpretationen getestet, nur die woertliche Variante funktioniert)
+
+## Sicherheit: Versand nur nach Bestaetigung
+
+`kontakt@mbo-tech-it.de` ist die offizielle Firmenadresse. Nach aussen
+versendete E-Mails sind schwerer zu widerrufen als ein interner
+Kalendereintrag. Deshalb - analog zum Kalender-Loeschen -: der System-Prompt
+weist Claude an, vor jedem `send_email`-Aufruf Empfaenger/Betreff/Text im
+Chat zur Bestaetigung vorzulegen und das Tool erst nach Zustimmung
+aufzurufen.
+
+## Architektur: zwei Wege, wie beim Kalender/Wetter kombiniert
+
+**Chat (live, wie beim Kalender):** Zwei neue Claude-Tools in
+`run_chat_completion`:
+- `list_recent_emails(limit)` - liest live per IMAP (`imaplib`, Python-
+  Standardbibliothek, keine neue Abhaengigkeit) die letzten N Nachrichten
+  aus INBOX (nur Header: From/Subject/Date, `BODY.PEEK[...]` damit der
+  ungelesen-Status nicht veraendert wird), gibt `{from, subject, date,
+  unread}` pro Mail zurueck. Betreffzeilen werden mit
+  `email.header.decode_header` dekodiert (RFC 2047, z.B. `=?utf-8?B?...?=`).
+- `send_email(to, subject, body)` - versendet per SMTP (`smtplib`,
+  Standardbibliothek) ueber Port 465 (implizites TLS). Nur nach
+  Chat-Bestaetigung aufzurufen (siehe oben).
+
+**Dashboard-Widget (gecacht, wie beim Wetter):** Neuer n8n-Workflow mit dem
+eingebauten Trigger-Node `Email Trigger (IMAP)`
+(`n8n-nodes-base.emailReadImap`, verifiziert vorhanden in dieser
+n8n-Version), der selbststaendig neue Nachrichten erkennt (kein eigener
+Schedule-Trigger noetig, das uebernimmt der Node):
+- `postProcessAction: "nothing"` - markiert Mails NICHT als gelesen, damit
+  das automatische Cachen den tatsaechlichen Lese-Status im Postfach nicht
+  verfaelscht
+- `format: "simple"` reicht (nur Header/Text, keine Anhaenge noetig)
+- Schreibt pro neuer Mail eine Zeile in eine neue Tabelle `email_cache`
+  (sender, subject, received_at)
+
+`GET /api/v1/emails` (geschuetzt wie alle anderen Routen) liest die
+neuesten Zeilen daraus fuer das Dashboard-Widget "Neue E-Mails".
+
+## Datenmodell
+
+```sql
+CREATE TABLE email_cache (
+    id SERIAL PRIMARY KEY,
+    sender VARCHAR(255) NOT NULL,
+    subject VARCHAR(500) NOT NULL,
+    received_at TIMESTAMP NOT NULL,
+    cached_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_email_cache_received_at ON email_cache(received_at);
+```
+
+Nur Metadaten (Absender/Betreff/Datum) werden dauerhaft gespeichert - keine
+E-Mail-Inhalte/Volltexte, um die Menge an gespeicherter Geschaeftskorrespondenz
+gering zu halten (die Chat-Tools lesen bei Bedarf live, ohne Zwischenspeicherung).
+
+## Fehlerbehandlung
+
+- IMAP/SMTP nicht erreichbar oder Login fehlgeschlagen: Chat-Tools werfen
+  eine Exception mit klarer Meldung, die als `tool_result` mit
+  `is_error: true` an Claude zurueckgeht (gleiches Muster wie beim Kalender).
+- `GET /api/v1/emails` bei leerem Cache: gibt ein leeres Array zurueck (kein
+  503) - anders als beim Wetter ist "noch keine neue Mail seit Start des
+  Workflows" ein normaler, kein Fehlerzustand.
+
+## Testing
+
+- Backend: Unit-Tests fuer die IMAP-Parsing-Funktion (RFC-2047-Betreffs
+  dekodieren, unread-Flag aus FLAGS-Antwort ableiten) und fuer den
+  SMTP-Sende-Aufruf, jeweils mit gemocktem `imaplib`/`smtplib`.
+- Manueller End-to-End-Test nach Deployment: Chat nach "was ist neu im
+  Postfach?" fragen (echte IMAP-Daten), eine Test-Mail an die eigene
+  Adresse per Chat versenden lassen (inkl. Bestaetigungs-Dialog), n8n-
+  Workflow aktivieren und pruefen, dass die Test-Mail in `email_cache`
+  auftaucht, Dashboard-Widget ansehen.
+
+## Out of Scope (bewusst nicht Teil dieser Phase)
+
+- Anhaenge (weder lesen noch versenden).
+- Antworten/Weiterleiten als eigene Aktion (nur neues `send_email`).
+- Loeschen/Verschieben von E-Mails.
+- Mehrere Postfaecher/Ordner (nur INBOX von kontakt@mbo-tech-it.de).
