chore: release v0.1.0.110

Disable backup export until passphrases match.
The download button stays inactive until both fields agree and meet the minimum length, so users cannot start export with a mismatch. Co-authored-by: Cursor <cursoragent@cursor.com>

+  Merge Git branches safely — fetch latest, merge or rebase onto master, resolve
+  conflicts intelligently, and verify the result. Use when the user asks to merge
+  branches, sync with master, resolve merge conflicts, or bring a feature branch
+  up to date.
+---
+
+# Git Merge
+
+Führe Branch-Merges sicher und nachvollziehbar aus. Für PR-Review, CI und
+Comment-Triage siehe den **babysit**-Skill — dieser Skill deckt die Git-Merge-
+Operation selbst ab.
+
+## Projekt-Kontext
+
+- **Basis-Branch:** `master` (nicht `main`)
+- **Monorepo:** `client/` (React PWA) und `server/` (Express API) — Konflikte
+  können in beiden liegen
+
+## Sicherheitsregeln (immer einhalten)
+
+- **Niemals** `git config` ändern
+- **Niemals** `--no-verify`, `--no-gpg-sign` o.ä. ohne explizite Anfrage
+- **Niemals** `push --force` auf `master` — bei Bedarf warnen und abbrechen
+- **Niemals** destruktive Befehle (`reset --hard`, `clean -fd`) ohne explizite Anfrage
+- **Niemals** interaktive Git-Befehle (`-i`-Flags) — nicht unterstützt
+- **Kein Commit** ohne explizite Anfrage des Users
+- **Kein Push** ohne explizite Anfrage des Users
+
+## Workflow
+
+### 1. Ausgangslage klären
+
+Parallel ausführen:
+
+```bash
+git status
+git branch -vv
+git log --oneline -5
+```
+
+Ermittle:
+
+- Aktueller Branch
+- Ziel-Branch (Standard: `master`)
+- Ob uncommittete Änderungen vorliegen
+- Ob der Branch einen Remote-Tracking-Branch hat
+
+**Bei uncommitteten Änderungen:** Stashen (`git stash push -m "pre-merge"`) nur
+mit Zustimmung oder wenn der User es verlangt hat. Sonst stoppen und melden.
+
+### 2. Merge-Strategie wählen
+
+| Situation | Empfehlung |
+|-----------|------------|
+| Feature-Branch aktuell halten | `git merge origin/master` (Merge-Commit) |
+| Linearer Verlauf gewünscht | `git rebase origin/master` (nur wenn User Rebase verlangt) |
+| Zwei Feature-Branches zusammenführen | `git merge <branch>` auf Ziel-Branch |
+
+**Standard:** Merge (nicht Rebase), es sei denn der User verlangt Rebase.
+
+### 3. Remote aktualisieren
+
+```bash
+git fetch origin
+```
+
+Vor dem Merge prüfen, wie weit der Branch hinter `origin/master` liegt:
+
+```bash
+git log --oneline HEAD..origin/master
+git log --oneline origin/master..HEAD
+```
+
+### 4. Merge ausführen
+
+**Feature-Branch mit master synchronisieren** (häuigster Fall):
+
+```bash
+git checkout <feature-branch>
+git merge origin/master
+```
+
+**Branch in master mergen** (nur wenn User das ausdrücklich will — normalerweise
+passiert das via PR):
+
+```bash
+git checkout master
+git pull origin master
+git merge <feature-branch>
+```
+
+Merge-Commit-Nachricht kurz und sachlich halten, z.B.:
+`Merge branch 'master' into feature/push-notifications-owner`
+
+### 5. Konflikte lösen
+
+Konfliktdateien finden:
+
+```bash
+git diff --name-only --diff-filter=U
+```
+
+**Pro Konfliktdatei:**
+
+1. Datei lesen und beide Seiten verstehen (HEAD = eigener Branch, incoming = gemergter Branch)
+2. Intent beider Änderungen erhalten — nicht blind eine Seite wählen
+3. Konfliktmarker entfernen (`<<<<<<<`, `=======`, `>>>>>>>`)
+4. Bei widersprüchlicher Intent: Merge abbrechen und User fragen
+
+```bash
+git merge --abort   # oder: git rebase --abort
+```
+
+**Typische Konflikt-Muster in diesem Projekt:**
+
+| Bereich | Hinweis |
+|---------|---------|
+| `package-lock.json` | Nach manueller Lösung `npm install` im betroffenen Paket (`client/` oder `server/`) ausführen |
+| i18n (`client/src/i18n/`) | Beide Sprachkeys (DE + EN) behalten, keine Keys verlieren |
+| Prisma/Schema | Migrationen beider Seiten zusammenführen, nicht überschreiben |
+| Verschlüsselung/Auth | Vorsichtig — keine Sicherheitslogik stillschweigend vereinfachen |
+
+Nach jeder gelösten Datei:
+
+```bash
+git add <file>
+```
+
+Merge abschließen (nur wenn User Commit verlangt hat):
+
+```bash
+git commit -m "$(cat <<'EOF'
+Merge branch 'master' into <feature-branch>
+
+EOF
+)"
+```
+
+### 6. Verifizieren
+
+Nach erfolgreichem Merge:
+
+```bash
+git status
+git log --oneline -5
+```
+
+Relevante Checks je nach betroffenen Bereichen:
+
+```bash
+# Client
+cd client && npm run build
+
+# Server
+cd server && npm run build
+```
+
+Bei Lockfile-Konflikten oder Dependency-Änderungen: Build in beiden Paketen prüfen.
+
+### 7. Abschluss
+
+- Ergebnis dem User mitteilen: welche Branches, wie viele Konflikte, was gelöst wurde
+- Bei `git stash`: erinnern, Stash wieder anzuwenden (`git stash pop`)
+- Push nur auf explizite Anfrage: `git push origin <branch>`
+
+## Wann abbrechen und fragen
+
+- Widersprüchliche fachliche Intent (z.B. beide Seiten ändern dieselbe Logik unterschiedlich)
+- Konflikte in Krypto-, Auth- oder Sync-Kernlogik ohne klares „richtig“
+- Merge würde `.env`, Credentials oder Secrets einschließen
+- User wollte nur Status prüfen, nicht tatsächlich mergen
+
+## Abgrenzung zu anderen Skills
+
+| Skill | Wann |
+|-------|------|
+| **merge** (dieser) | Git merge/rebase, Konflikte, Branch sync |
+| **babysit** | PR merge-ready: Comments, CI, PR-Konflikte im PR-Kontext |
+| **creating-pull-requests** | PR erstellen und pushen |

+# Kapteins Daagbok
+
+Digitales Yacht-Logbuch als Progressive Web App (PWA) — **kostenlos**, **werbefrei**, offline-fähig, End-to-End-verschlüsselt und mit Passkey-Anmeldung.
+
+**Live:** [kapteins-daagbok.eu](https://kapteins-daagbok.eu) · **Demo:** [kapteins-daagbok.eu/demo](https://kapteins-daagbok.eu/demo)
+
+## Überblick
+
+Kapteins Daagbok richtet sich an private Skipper und Yachtbesitzer, die ihr Bordlogbuch digital führen möchten. Die App speichert Schiffsdaten, Crew-Profile und Reisetage (Törns) in einem Format, das an übliche nautische Logbuch-Vorlagen angelehnt ist.
+
+Alle sensiblen Inhalte werden **clientseitig verschlüsselt** (Web Crypto API). Der Server sieht nur ciphertext — eine Zero-Knowledge-Architektur. Daten liegen zusätzlich lokal in IndexedDB (Dexie.js) und synchronisieren im Hintergrund, sodass die App **auch offline** auf See nutzbar ist.
+
+## Funktionen
+
+- **Passkey-Authentifizierung** (WebAuthn) mit optionaler Recovery-Phrase und lokalem PIN-Fallback
+- **Mehrere Logbücher** pro Benutzerkonto — eigene Logbücher und per Einladung geteilte Logbücher (Crew-Zugang) klar getrennt
+- **Reisetage** mit Hafen, Wetter, Tankständen, Ereignissen und Tagesnummer
+- **Kompass-Dial** für MgK- und RwK-Kurse — Ring-Eingabe, Gradfeld, Schrittweite 1°/5°/10° (maritime Orientierung: 0° = Nord)
+- **GPS-Tracks** (GPX/KML/GeoJSON-Upload, Karte, Statistiken)
+- **Foto-Anhänge** pro Reisetag
+- **Passkey-Signaturen** für Skipper und Crew (hybride elektronische Signatur)
+- **Schiffsdaten** und **Crew-Profile** (Skipper + Mitglieder)
+- **Statistik-Dashboard** — Strecken, Verbrauch, Segel/Motor, Hafenkette (pro Logbuch oder accountweit)
+- **Benutzerprofil** — kontoweite Einstellungen: Darstellung (Theme, Hell/Dunkel), OpenWeatherMap-API-Key, Web Push, PWA-Installation, Onboarding-Tour, Passkey-Verwaltung, Account-Statistik
+- **Kollaboration** — Crew per Einladungslink einladen (Schreib- oder Lesezugriff)
+- **Push-Benachrichtigungen** (optional) — Logbuch-Eigner per Web Push informieren, wenn Crew Änderungen synchronisiert (ohne Klartext-Inhalte; Opt-in im Benutzerprofil)
+- **Read-only-Freigabe** — öffentlicher Lese-Link für Dritte
+- **Export** — PDF pro Reisetag, CSV-Download/-Teilen
+- **Backup & Wiederherstellung** — vollständiges verschlüsseltes Logbuch-Backup (Einträge, Fotos, GPS, Crew, Schiff) als `.daagbok.json`; Restore auf gleichem oder neuem Account
+- **Feedback** — Bug-, Feature- und allgemeine Rückmeldungen aus der App (serverseitig via [Ntfy](https://ntfy.sh) oder self-hosted)
+- **PWA** — installierbar auf iOS/Android, Offline-Modus, Update-Hinweise
+- **Mehrsprachig** — Deutsch und Englisch
+- **Demo-Logbuch & Onboarding-Tour** für neue Nutzer (auch unter `/demo` ohne Anmeldung)
+
+### Benutzerprofil vs. Logbuch-Einstellungen
+
+| Bereich | Inhalt |
+|---------|--------|
+| **Benutzerprofil** | Theme, Farbschema, Wetter-API-Key, Push, PWA, Tour, Passkeys, Account löschen |
+| **Logbuch-Einstellungen** | Crew-Einladungen, öffentliche Freigabe, Backup & Wiederherstellung (nur Eigner) |
+
+## Architektur
+
+```
+┌─────────────────┐     HTTPS/API        ┌─────────────────┐
+│  React PWA      │ ◄──────────────────► │  Express API    │
+│  Vite + Dexie   │   (nur ciphertext)   │  Prisma + PG    │
+│  IndexedDB      │                      │  PostgreSQL     │
+└─────────────────┘                      └─────────────────┘
+```
+
+| Schicht | Technologie |
+|---------|-------------|
+| Frontend | React 19, TypeScript, Vite, vite-plugin-pwa |
+| Lokaler Speicher | Dexie.js (IndexedDB), Hintergrund-Sync |
+| Backend | Node.js, Express, Prisma |
+| Datenbank | PostgreSQL 16 |
+| Auth | WebAuthn (Passkeys) + signiertes HttpOnly-Session-Cookie (`daagbok_session`) |
+| Krypto | Web Crypto API (AES-GCM), BIP39 Recovery |
+| Push (optional) | Web Push (VAPID), Custom Service Worker (`injectManifest`) |
+| Feedback (optional) | Ntfy (HTTP Publish) |
+
+### Rollen & Zugriff
+
+| Rolle | Bedeutung |
+|-------|-----------|
+| **Owner** | Logbuch angelegt; voller Zugriff, Einladungen, Backup, Löschen; optional Push bei Crew-Änderungen |
+| **Collaborator (WRITE)** | Per Einladung; Einträge bearbeiten und als Crew signieren |
+| **Collaborator (READ)** | Nur Lesen (z. B. öffentlicher Share-Link) |
+
+Skipper- und Crew-Profile im Logbuch sind **Inhaltsdaten** (verschlüsselt), nicht an den Account gebunden. Ein Account kann gleichzeitig Owner eines eigenen und Collaborator in fremden Logbüchern sein.
+
+### Authentifizierung & Session
+
+| Schicht | Verhalten |
+|---------|-----------|
+| **Login** | WebAuthn (`/api/auth/login-verify`) — danach HttpOnly-Cookie, 7 Tage gültig |
+| **API-Aufrufe** | Cookie `credentials: 'include'` (Client: `apiFetch`) — kein `X-User-Id` |
+| **Master-Key** | Nur im RAM; nach Reload Entsperren per Passkey oder lokalem PIN |
+| **Step-up** | Konto löschen, PRF-Enrollment: frische Passkey-Bestätigung (`/api/auth/reauth-*`) |
+| **Sync WRITE** | Server lehnt Schreib-Sync für Collaborator mit `READ` ab |
+
+Öffentliche Routen (ohne Session): Registrierung/Login-Optionen, Einladungsdetails, Read-only-Share (`share-pull`), Health-Check, VAPID-Public-Key.
+
+## Backup & Wiederherstellung
+
+Nur der **Logbuch-Eigner** kann unter **Logbuch-Einstellungen → Backup & Wiederherstellung** ein vollständiges Backup erstellen:
+
+1. Backup-Passphrase wählen (min. 8 Zeichen, getrennt von der Datei aufbewahren)
+2. Download als `.daagbok.json` — enthält alle verschlüsselten Payloads inkl. **Fotos** und GPS-Tracks
+3. **Wiederherstellen** in einem beliebigen Account (nach Registrierung/Login): Datei + Passphrase
+
+Vor dem Löschen eines Logbuchs weist die App auf diese Funktion hin. Crew-Einladungen und Passkey-Signaturen werden nicht mitübertragen — Inhalte bleiben lesbar, Signaturen auf neuem Account ggf. nicht mehr verifizierbar.
+
+## Push-Benachrichtigungen (optional)
+
+Logbuch-**Eigner** können im **Benutzerprofil** Web Push aktivieren. Sobald ein eingeladenes Crewmitglied mit Schreibrechten (`WRITE`) Änderungen synchronisiert, erhält der Owner eine **generische** Benachrichtigung — der Server kennt keine Logbuch-Inhalte (Zero-Knowledge).
+
+| Aspekt | Verhalten |
+|--------|-----------|
+| Auslöser | Erfolgreicher Sync-Push durch Collaborator (`create`/`update`) |
+| Aggregation | Mehrere Änderungen in einem Sync → eine Benachrichtigung pro Logbuch |
+| Drosselung | Max. eine Push-Nachricht pro Logbuch alle 3 Minuten |
+| Klick | Öffnet die App auf dem betroffenen Logbuch |
+
+**Voraussetzungen:**
+
+- HTTPS (Produktion)
+- VAPID-Schlüssel auf dem Server (`VAPID_PUBLIC_KEY`, `VAPID_PRIVATE_KEY`, `VAPID_SUBJECT`)
+- Browser-Berechtigung „Benachrichtigungen“; auf **iOS** installierte PWA ab iOS 16.4+
+
+Schlüssel erzeugen: `npx web-push generate-vapid-keys` (im `server/`-Verzeichnis oder global).
+
+Ausführlicher Implementierungs- und Testplan: [docs/push-notifications-plan.md](docs/push-notifications-plan.md).
+
+## Feedback (optional)
+
+Eingeloggte Nutzer können über das Feedback-Formular in der App Rückmeldungen senden. Der Server leitet sie an einen **Ntfy**-Topic weiter (kein Klartext-Logbuch auf dem Server).
+
+| Variable | Bedeutung |
+|----------|-----------|
+| `NTFY_SERVER` | Basis-URL (Standard: `https://ntfy.sh`) |
+| `NTFY_TOPIC` | Topic-Name (ohne URL) |
+| `NTFY_TOKEN` | Optional: Access-Token für geschützte Topics |
+
+Ohne `NTFY_TOPIC` antwortet die API mit „nicht konfiguriert“. Rate-Limiting und einfacher Spam-Schutz sind serverseitig aktiv.

+
+## Voraussetzungen
+
+- **Node.js** 20+
+- **npm**
+- **Docker** (für PostgreSQL in der Entwicklung oder den vollständigen Stack)
+- Optional: eigener OpenWeatherMap-API-Key im **Benutzerprofil** (sonst serverseitiger Key aus `.env`)
+- Optional: VAPID-Schlüssel für Web Push (siehe Abschnitt Push-Benachrichtigungen)
+- Optional: Ntfy-Topic für Feedback (siehe Abschnitt Feedback)
+
+## Lokale Entwicklung
+
+### 1. Abhängigkeiten installieren
+
+```bash
+cd server && npm ci && cd ..
+cd client && npm ci && cd ..
+```
+
+### 2. Umgebungsvariablen
+
+```bash
+cp .env.example .env
+```
+
+Kopiere `.env.example` nach `.env` und passe mindestens an:
+
+| Variable | Dev (Vite) | Produktion |
+|----------|------------|------------|
+| `RP_ID` | `localhost` | `kapteins-daagbok.eu` |
+| `ORIGIN` | `http://localhost:5173` | `https://kapteins-daagbok.eu` |
+| `SESSION_SECRET` | empfohlen (≥ 32 Zeichen) | **Pflicht** |
+
+`ORIGIN` muss **exakt** der Frontend-URL entsprechen (CORS + Session-Cookie). Das Backend lädt `.env` aus dem Projektroot und optional `server/.env`.
+
+```
+DATABASE_URL="postgresql://postgres:postgres@localhost:5432/daagbox?schema=public"
+OpenWeatherMapAPIKey=          # Fallback für Wetter-Abruf, wenn Nutzer keinen eigenen Key hat
+RP_ID=localhost
+ORIGIN=http://localhost:5173
+SESSION_SECRET=                 # openssl rand -base64 48 (in Prod Pflicht)
+# Optional — Web Push (npx web-push generate-vapid-keys)
+VAPID_PUBLIC_KEY=
+VAPID_PRIVATE_KEY=
+VAPID_SUBJECT=mailto:support@kapteins-daagbok.eu
+# Optional — Feedback via Ntfy
+NTFY_SERVER=https://ntfy.sh
+NTFY_TOPIC=
+NTFY_TOKEN=
+```
+
+`./scripts/start-dev.sh` prüft `ORIGIN` und `SESSION_SECRET` beim Start und gibt Hinweise aus.
+
+### 3. Datenbank & Schema
+
+Das Dev-Skript startet PostgreSQL in Docker (`postgres-daagbox`). Schema anwenden:
+
+```bash
+cd server && npx prisma db push && cd ..
+```
+
+### 4. Dev-Server starten
+
+```bash
+./scripts/start-dev.sh
+```
+
+| Dienst | URL |
+|--------|-----|
+| Frontend (Vite) | http://localhost:5173 |
+| Backend API | http://localhost:5000 |
+| Health Check | http://localhost:5000/api/health |
+| Public Demo | http://localhost:5173/demo |
+
+### 5. Qualität & Tests
+
+Vor jedem Deploy auf [kapteins-daagbok.eu](https://kapteins-daagbok.eu/) (kein externes CI):
+
+```bash
+npm run check
+# oder: ./scripts/predeploy-check.sh
+```
+
+Einzeln: `npm test` (Client + Server) · `npm run build` · optional `npm run lint` (Client, noch nicht in `check`)
+
+- **Client:** Vitest für Utils, i18n, Services
+- **Server:** Smoke-Tests (`/api/health`, Auth-Guards) mit Supertest — siehe `server/src/api.smoke.test.ts`
+
+## Docker (produktionsnah)
+
+Gesamten Stack lokal bauen und starten:
+
+```bash
+./scripts/start-dev-docker.sh
+```
+
+Frontend: http://localhost · API: http://localhost/api/health · Demo: http://localhost/demo
+
+Umgebungsvariablen in `.env` setzen — mindestens `RP_ID`, `ORIGIN` (z. B. `http://localhost`), `SESSION_SECRET` und für Docker Compose `POSTGRES_PASSWORD`. Für Push die VAPID-Variablen an den Backend-Container durchreichen (`docker-compose.yml` → `backend.environment`). Für Feedback `NTFY_*` setzen.
+
+## Deployment
+
+Produktions-Update auf den Server (konfigurierbar via Umgebungsvariablen). Führt vor dem SSH-Deploy automatisch [`predeploy-check.sh`](scripts/predeploy-check.sh) aus (`npm run check`):
+
+
+```bash
+./scripts/update-prod.sh
+```
+
+Standard-Ziel: `root@10.0.0.25:/opt/kapteins-daagbok` — per `REMOTE_HOST`, `REMOTE_USER`, `REMOTE_DIR` überschreibbar.
+
+Auf dem Server müssen `.env` u. a. `POSTGRES_PASSWORD`, `RP_ID`, `ORIGIN` (`https://kapteins-daagbok.eu`), `SESSION_SECRET` (≥ 32 Zeichen), `TRUST_PROXY` (NPM, z. B. `172.16.10.10` oder `1`) und bei Push `VAPID_*` enthalten. Optional `NTFY_*` für Feedback. Nach Schema-Änderungen: `npx prisma db push` im Backend-Container.
