+  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 |

+# Implementierungsvorschlag: Hybride elektronische Signatur (Variante C)
+
+**Status:** Entwurf  
+**Datum:** 2026-05-29  
+**Scope:** Skipper-Freigabe per Passkey, Crew-Freigabe per Passkey *oder* klassische Unterschrift (Pad/Text)
+
+---
+
+## 1. Ziel
+
+Die bestehenden Felder `signSkipper` und `signCrew` sollen um eine **identitätsgebundene Passkey-Freigabe** ergänzt werden, ohne die Papier-Tradition vollständig zu ersetzen:
+
+| Rolle | Primär | Fallback |
+|-------|--------|----------|
+| **Skipper** | Passkey (WebAuthn-Assertion, an Eintrags-Hash gebunden) | SignaturePad / getippter Name (Offline, Gastgerät ohne Passkey) |
+| **Crew** | Passkey (nur für eingeladene Collaborators mit WRITE) | SignaturePad / getippter Name (Gäste ohne Konto) |
+
+**Nicht-Ziel (v1):** Qualifizierte elektronische Signatur (QES/eIDAS), serverseitiges Audit-Log (optional Phase 2), Multi-Device-Signatur-Workflow für Crew auf separatem Gerät.
+
+---
+
+## 2. Produktverhalten (UX)
+
+### 2.1 Skipper-Bereich
+
+```
+┌─────────────────────────────────────────────┐
+│ Skipper-Freigabe                            │
+│ ┌─────────────────────────────────────────┐ │
+│ │ ✓ Signiert von max@see  29.05.26 14:32 │ │  ← Passkey-Signatur vorhanden
+│ │   [Erneut freigeben]  [Klassisch …]    │ │
+│ └─────────────────────────────────────────┘ │
+└─────────────────────────────────────────────┘
+```
+
+**Standard-Flow beim Speichern:**
+
+1. Nutzer füllt Logbuchseite aus und tippt auf „Speichern“.
+2. Wenn `signSkipper` leer ist und Netzwerk verfügbar → **Passkey-Dialog** (User Verification).
+3. Nach erfolgreicher Assertion wird der Eintrag verschlüsselt gespeichert.
+4. Wenn Offline oder Passkey fehlschlägt → Dialog: *„Offline / Passkey nicht verfügbar — klassische Unterschrift verwenden?“* → SignaturePad.
+
+**Regeln:**
+
+- Passkey-Skipper-Signatur ist an den **Eintragsinhalt ohne Signaturfelder** gebunden. Änderungen an Datum, Route, Tankständen etc. **invalidieren** die Signatur (Badge „Signatur ungültig — erneut freigeben“).
+- Der Logbuch-**Owner** oder ein Collaborator mit **WRITE** darf Skipper-Freigabe leisten (konfigurierbar: v1 = jeder WRITE-Nutzer auf dem Gerät).
+- Bereits signierte Einträge im **readOnly**-Modus: nur Anzeige, kein erneutes Signieren.
+
+### 2.2 Crew-Bereich
+
+```
+┌─────────────────────────────────────────────┐
+│ Crew-Freigabe                               │
+│ ○ Passkey (empfohlen)   ○ Klassisch         │  ← Toggle nur wenn Collaborators existieren
+│ [Mit Passkey freigeben]                     │
+│ — oder —                                    │
+│ [SignaturePad wie bisher]                   │
+└─────────────────────────────────────────────┘
+```
+
+**Crew-Passkey:**
+
+- Button „Mit Passkey freigeben“ startet WebAuthn mit `allowCredentials` **nur für Collaborators dieses Logbuchs** (Server liefert Credential-IDs).
+- Auf einem gemeinsamen Tablet kann die Crew-Mitperson ihren Passkey wählen, ohne das Kapitäns-Konto zu verlassen.
+- Ohne Collaborators: nur SignaturePad (wie heute).
+
+**Crew ohne Konto:** unverändert Pad oder Text — kein Passkey-Zwang.
+

+  end
+  E->>DB: encryptJson(entry inkl. signSkipper)
+```
+
+---
+
+## 3. Datenmodell
+
+### 3.1 Neue Typen (`client/src/types/signatures.ts`)
+
+```typescript
+/** Passkey-Freigabe v1 — rein in E2E-Payload, kein Klartext auf dem Server */
+export interface PasskeySignature {
+  kind: 'passkey'
+  version: 1
+  role: 'skipper' | 'crew'
+  userId: string
+  username: string
+  credentialId: string        // base64url
+  signedAt: string            // ISO-8601 UTC
+  entryHash: string           // base64url SHA-256
+  /** Client-seitig gespeichert für Offline-Anzeige; Server verifiziert bei Erstellung */
+  clientVerified: boolean
+}
+
+/** Legacy: string = PNG data URL oder getippter Name */
+export type SignatureValue = string | PasskeySignature
+
+export interface LogEntrySignatures {
+  signSkipper?: SignatureValue
+  signCrew?: SignatureValue
+}
+```
+
+### 3.2 Abwärtskompatibilität
+
+Bestehende Einträge speichern `signSkipper`/`signCrew` als `string`. Keine Migration nötig.
+
+Hilfsfunktionen in `client/src/utils/signatures.ts` erweitern:
+
+```typescript
+export function isPasskeySignature(v: unknown): v is PasskeySignature
+export function normalizeSignature(v: unknown): SignatureValue | undefined
+export function formatSignatureForExport(v: SignatureValue | undefined, labels: ExportLabels): string
+export function isSignatureValidForEntry(sig: PasskeySignature, entryHash: string): boolean
+```
+
+**Export-Texte (i18n):**
+
+| Key | DE | EN |
+|-----|----|----|
+| `logs.sign_passkey_export` | `Passkey: {{username}} ({{date}})` | `Passkey: {{username}} ({{date}})` |
+| `logs.sign_invalid` | Signatur ungültig | Signature invalid |
+| `logs.sign_with_passkey` | Mit Passkey freigeben | Sign with Passkey |
+| `logs.sign_classic_fallback` | Klassische Unterschrift | Classic signature |
+| `logs.sign_offline_hint` | Passkey-Freigabe erfordert Internet | Passkey signing requires internet |
+
+### 3.3 Kanonischer Eintrags-Hash
+
+Neue Datei: `client/src/utils/entryCanonicalHash.ts`
+
+```typescript
+const SIGNATURE_KEYS = ['signSkipper', 'signCrew'] as const
+
+/** Stabil sortiertes JSON → SHA-256 → base64url */
+export async function hashEntryForSigning(entry: Record<string, unknown>): Promise<string>
+```
+
+**In Hash einbeziehen:** alle Felder außer `signSkipper`, `signCrew` und transienten UI-Feldern.  
+**Reihenfolge:** Keys alphabetisch sortieren, Arrays in definierter Reihenfolge (events nach `time`), Zahlen normalisiert.
+
+Beim Laden eines Eintrags: `computedHash !== sig.entryHash` → UI-Warnung.
+
+---
+
+## 4. Server-API
+
+Neuer Router: `server/src/routes/sign.ts` → Mount unter `/api/sign`
+
+Auth wie bestehend: HttpOnly-Session-Cookie `daagbok_session` nach WebAuthn (`server/src/middleware/auth.ts`, Client `apiFetch` mit `credentials: 'include'`).
+
+### 4.1 `POST /api/sign/options`
+
+**Request:**
+
+```json
+{
+  "logbookId": "uuid",
+  "entryId": "uuid",
+  "entryHash": "base64url-sha256",
+  "role": "skipper" | "crew"
+}
+```
+
+**Autorisierung:**
+
+- Nutzer ist Owner **oder** Collaborator mit WRITE auf `logbookId`.
+- Für `role: "crew"`: optional prüfen, dass mindestens ein anderer Collaborator existiert (Skipper darf auch Crew signieren in v1).
+
+**Challenge-Konstruktion:**
+
+```typescript
+const payload = `${entryId}:${entryHash}:${role}:${randomNonce}`
+const challenge = base64url(sha256(payload))
+```
+
+In-Memory-Store (analog `activeChallenges` in `auth.ts`):
+
+```typescript
+signingChallenges.set(challenge, {
+  userId, logbookId, entryId, entryHash, role, expiresAt
+})
+```
+
+**Response:** WebAuthn `PublicKeyCredentialRequestOptions`
+
+- `allowCredentials`: Credentials des **anfragenden** Users (Skipper) **oder** bei `role: crew` alle Credentials der Logbook-Collaborators (Query über `Collaboration` + `Credential`).
+- **Kein PRF-Extension** — reine User-Verifikation, nicht Key-Derivation.
+- `userVerification: 'required'`
+
+### 4.2 `POST /api/sign/verify`
+
+**Request:**
+
+```json
+{
+  "credentialResponse": { /* WebAuthn */ },
+  "challenge": "...",
+  "logbookId": "...",
+  "entryId": "...",
+  "entryHash": "...",
+  "role": "skipper" | "crew"
+}
+```
+
+**Verifikation:**
+
+1. Challenge aus Store (TTL 5 Min, one-time).
+2. `entryHash` und Metadaten müssen mit gespeichertem Kontext übereinstimmen.
+3. `verifyAuthenticationResponse` wie in `auth.ts` `/login-verify`.
+4. Credential-User muss berechtigt sein (Owner/Collaborator WRITE; bei Crew-Signatur: Credential gehört zu einem Collaborator des Logbuchs).
+
+**Response:**
+
+```json
+{
+  "verified": true,
+  "userId": "...",
+  "username": "...",
+  "credentialId": "...",
+  "signedAt": "2026-05-29T12:00:00.000Z"
+}
+```
+
+**Wichtig:** Server speichert in v1 **keinen** Eintragsinhalt und keine Assertion — nur verifiziert und gibt Metadaten zurück. Der Client packt `PasskeySignature` ins E2E-Blob.
+
+### 4.3 Optional Phase 2: Audit-Tabelle
+
+```prisma
+model EntrySignatureAudit {
+  id           String   @id @default(uuid())
+  logbookId    String
+  entryId      String
+  userId       String
+  role         String   // skipper | crew
+  entryHash    String
+  credentialId String
+  signedAt     DateTime @default(now())
+
+  @@index([logbookId, entryId])
+}
+```
+
+Ermöglicht spätere Prüfung ohne Entschlüsselung des Eintrags. Bewusst **ohne** Klartext-Inhalt.
+
+---
+
+## 5. Client-Implementierung
+
+### 5.1 Neuer Service: `client/src/services/entrySigning.ts`
+
+```typescript
+export async function signLogEntry(params: {
+  logbookId: string
+  entryId: string
+  entryHash: string
+  role: 'skipper' | 'crew'
+}): Promise<PasskeySignature>
+
+export async function listCollaboratorCredentialIds(logbookId: string): Promise<string[]>
+// Wrapper für /api/sign/options + startAuthentication + /api/sign/verify
+// Kein PRF — separates Flow von loginUser()
+```
+
+Wiederverwendung: `@simplewebauthn/browser` `startAuthentication`, Muster aus `auth.ts` (Retry ohne PRF entfällt hier).
+
+### 5.2 UI-Komponenten
+
+| Datei | Aufgabe |
+|-------|---------|
+| `client/src/components/SignatureSection.tsx` | Container für Skipper + Crew, Modus-Toggle |
+| `client/src/components/PasskeySignButton.tsx` | Button, Loading, Fehler, Erfolgs-Badge |
+| `client/src/components/SignaturePad.tsx` | unverändert für Fallback |
+
+**`LogEntryEditor.tsx` Änderungen:**
+
+- State: `signSkipper: SignatureValue | ''`, `signCrew: SignatureValue | ''`
+- Beim Submit: zuerst `entryData` ohne Signaturen hashen, dann Skipper-Passkey anstoßen (wenn gewählt/leer+online).
+- `readOnly`: Passkey-Badge + „Signiert von … am …“; Pad disabled.
+
+**`LogEntriesList.tsx`:** Default für neue Einträge `signSkipper: undefined` (nicht leerer String erzwingen).
+
+### 5.3 Speichern-Logik (Pseudocode)
+
+```typescript
+async function handleSubmit() {
+  const entryData = buildEntryPayload({ signSkipper: undefined, signCrew: undefined })
+  const entryHash = await hashEntryForSigning(entryData)
+
+  let skipperSig = signSkipper
+  if (skipperSignMode === 'passkey' && !isPasskeySignature(skipperSig)) {
+    skipperSig = await signLogEntry({ logbookId, entryId, entryHash, role: 'skipper' })
+  }
+
+  const finalEntry = { ...entryData, signSkipper: skipperSig, signCrew: signCrew }
+  await encryptAndSave(finalEntry)
+}
+```
+
+Crew-Passkey: separater Button (nicht zwingend beim Speichern), damit Crew-Mitglied nach dem Skipper signieren kann.
+
+### 5.4 Export-Anpassungen
+
+**CSV** (`csvExport.ts`):
+
+```typescript
+formatSignatureForExport(value, {
+  imagePlaceholder: t('logs.sign_export_image'),
+  passkeyTemplate: (sig) => i18n.t('logs.sign_passkey_export', { username: sig.username, date: format(sig.signedAt) })
+})
+```
+
+**PDF** (`pdfExport.ts`):
+
+- Passkey: zweizeilig — `SIGNIERT / SIGNED` + Username + Datum (kein Bild).
+- Bild/Text: bestehende Logik.
+
+---
+
+## 6. Offline-Verhalten
+
+| Situation | Verhalten |
+|-----------|-----------|
+| Online + Passkey | Standard Skipper-Flow |
+| Offline | Passkey deaktiviert; Hinweis + SignaturePad |
+| Eintrag offline gespeichert, später online | Kein Auto-Nachsignieren; Nutzer tippt „Mit Passkey freigeben“ |
+| Passkey-Signatur vorhanden, Inhalt geändert | Signatur als ungültig markieren, erneute Freigabe nötig |
+
+Kein Offline-Queue für WebAuthn in v1 — zu komplex (Challenge-Ablauf, Counter-Sync).
+
+---
+
+## 7. Sicherheit
+
+| Risiko | Mitigation |
+|--------|------------|
+| Signatur ohne Inhaltsbindung | `entryHash` in Challenge + im `PasskeySignature`-Objekt |
+| Fremder signiert Skipper-Feld | Server prüft WRITE auf Logbook + Credential-Zugehörigkeit |
+| Replay der Assertion | Challenge one-time, 5 Min TTL |
+| Manipulation nach Signatur | Client prüft Hash bei Anzeige; Export zeigt „invalid“ |
+| E2E vs. Audit | v1 nur E2E-Metadaten; Audit optional Phase 2 |
+| Login-Session vs. Signatur | Separater Endpoint, `userVerification: required`, kein PRF |
+
+**Hinweis:** Gespeicherte `PasskeySignature` im E2E-Blob ist **selbst nicht kryptografisch signiert** durch den Server (Server sieht Payload nicht). Vertrauen basiert auf: (a) erfolgreiche Server-Verifikation zum Zeitpunkt der Erstellung, (b) Hash-Bindung, (c) optional Audit-Log in Phase 2. Für stärkere Non-Repudiation: Assertion-Response oder Server-Signatur über Hash in Audit speichern.
+
+---
+
+## 8. Implementierungsphasen
+
+### Phase 1 — Fundament (MVP)
+
+**Ziel:** Skipper Passkey + Crew Pad, Hash, Export, Fallback.
+
+| # | Task | Dateien |
+|---|------|---------|
+| 1.1 | Typen + Signature-Utils | `types/signatures.ts`, `utils/signatures.ts`, `utils/entryCanonicalHash.ts` |
+| 1.2 | Server `/api/sign/*` | `server/src/routes/sign.ts`, `server/src/index.ts` (mount) |
+| 1.3 | Client `entrySigning.ts` | `client/src/services/entrySigning.ts` |
+| 1.4 | UI Skipper Passkey + Pad-Fallback | `PasskeySignButton.tsx`, `SignatureSection.tsx`, `LogEntryEditor.tsx` |
+| 1.5 | Crew nur Pad (unverändert) | `SignatureSection.tsx` |
+| 1.6 | Export CSV/PDF | `csvExport.ts`, `pdfExport.ts` |
+| 1.7 | i18n DE/EN | `locales/de.json`, `locales/en.json` |
+
+**Akzeptanzkriterien:**
+
+1. Skipper kann Eintrag online per Passkey freigeben; PDF/CSV zeigen Username + Datum.
+2. Offline → Pad-Fallback funktioniert.
+3. Alte Einträge (String-Signaturen) laden und exportieren unverändert.
+4. Geänderte Felder nach Passkey-Signatur → Warnung „Signatur ungültig“.
+
+### Phase 2 — Crew Passkey
+
+| # | Task | Dateien |
+|---|------|---------|
+| 2.1 | Collaborator-Credentials in `/sign/options` | `sign.ts`, ggf. `collaboration.ts` |
+| 2.2 | Crew-Toggle Passkey vs. Pad | `SignatureSection.tsx` |
+| 2.3 | Collaborator-Liste für UI | `SettingsForm` / neuer Hook `useLogbookCollaborators` |
+
+**Akzeptanzkriterien:**
+
+1. Eingeladener WRITE-Collaborator kann Crew-Feld per eigenem Passkey signieren.
+2. Gäste ohne Konto nutzen weiterhin Pad.
+
+### Phase 3 — Härtung (optional)
+
+- Prisma `EntrySignatureAudit`
+- „Signatur prüfen“-Button (Re-Verify gegen Server, wenn online)
+- Einstellung im Logbook: „Skipper-Freigabe nur Passkey“ (Pad-Fallback deaktivieren)
+- Tests: Unit-Tests für `hashEntryForSigning`, Integrationstest `/sign/verify`
+
+---
+
+## 9. Testplan
+
+### Manuell
+
+- [ ] DE/EN: Export-Texte für Passkey, Pad, leer
+- [ ] Skipper Passkey → Speichern → Reload → Badge sichtbar
+- [ ] Eintrag ändern → ungültige Signatur
+- [ ] Offline speichern mit Pad
+- [ ] Legacy-Eintrag mit PNG-Signatur lädt korrekt

+
+## 10. Aufwandsschätzung
+
+| Phase | Aufwand |
+|-------|---------|
+| Phase 1 (MVP) | ~2–3 Tage |
+| Phase 2 (Crew Passkey) | ~1 Tag |
+| Phase 3 (Audit + Tests) | ~1–2 Tage |
+
+---
+
+## 11. Offene Entscheidungen (vor Implementierung klären)
+
+1. **Skipper-Pflicht:** Muss jeder Eintrag Passkey-signiert sein, oder optional wie heute?
+   - *Empfehlung v1:* Optional; Passkey wird beim Speichern **angeboten**, Pad bei Offline.
+
+2. **Wer darf Skipper signieren?** Nur Owner oder jeder WRITE-Nutzer?
+   - *Empfehlung v1:* Jeder WRITE-Nutzer (typisch: Kapitän auf eigenem Gerät).
+
+3. **Pad-Fallback dauerhaft erlauben?**
+   - *Empfehlung:* Ja (Variante C); später Logbook-Setting zum Erzwingen von Passkey.
+
+4. **Crew-Passkey beim Speichern oder separater Schritt?**
+   - *Empfehlung:* Separater Button — Crew signiert oft nach dem Skipper.

+# 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.
