+# Backup-Format v2 — Design
+
+**Status:** Implementiert in `feature/backup-format-v2` (`BACKUP_VERSION = 2`, Datei `*.daagbok`).
+
+**Ziel:** Logbuch-Backups skalieren für viele Reisetage, Fotos, Voice-Memos und GPS-Tracks — ohne den gesamten Inhalt als eine große JSON-Datei im Browser-RAM zu halten.
+
+**Ausgangslage:** v1 (`BACKUP_VERSION = 1`, Datei `*.daagbok.json`) serialisiert alle Payloads in ein einziges JSON-Objekt mit Pretty-Print. Binärdaten stecken doppelt als Base64-Strings in `encryptedData`. Import nutzt `file.text()` + `JSON.parse()` auf der vollen Datei.
+
+**Entscheidung:** Keine Abwärtskompatibilität zu v1 — es gibt noch keine produktiven User-Backups. v1-Code und `-json`-Dateiendung wurden durch v2 ersetzt.
+
+---
+
+## 1. Anforderungen
+
+### Funktional
+
+| ID | Anforderung |
+|----|-------------|
+| B-01 | Export enthält **alle** lokalen Logbuch-Payloads: yacht, deviation, crews, entries, photos, voiceMemos, gpsTracks, **logbookCrewSelection**, **logbookVesselSelection**, **nmeaArchives**. |
+| B-02 | E2E-Verschlüsselung bleibt: Logbuch-Key mit Backup-Passphrase (PBKDF2) gewrappt; Payload-Blobs unverändert wie in Dexie (AES-GCM über `encryptJson`). |
+| B-03 | Medien (Fotos, Voice-Memos) als **binäre Blob-Dateien** im Archiv, nicht als Base64 in JSON. |
+| B-04 | Strukturdaten (Manifest, kleine Metadaten) als **kompaktes JSON** (ein Zeile, kein Pretty-Print). |
+| B-05 | Gesamtarchiv **DEFLATE-komprimiert** (ZIP). |
+| B-06 | Preview (Titel, Counts, Export-Datum) ohne vollständiges Entpacken aller Medien — nur Manifest + Key-Entschlüsselung. |
+| B-07 | Restore-Optionen wie heute: `overwrite`, `assignNewId`, Konflikt bei gleicher ID. |
+| B-08 | Nach Restore: Sync-Queue wie heute befüllen, optional `syncLogbook` wenn online. |
+| B-09 | Export vor Download optional mit **Fortschrittsanzeige** (Anzahl Blobs / Bytes). |
+
+### Nicht-Ziele (v2)
+
+- Inkrementelles / dedupliziertes Backup über mehrere Dateien.
+- Backup auf dem Server (nur lokaler Download wie heute).
+- Klartext-Manifest oder unverschlüsselte Medien.
+- Account-weites Multi-Logbuch-Archiv (weiterhin **ein Logbuch pro Datei**).
+
+### Akzeptanzkriterien (UAT)
+
+1. Logbuch mit 50 Fotos + 20 Voice-Memos exportieren → Datei `.daagbok` deutlich kleiner als vergleichbares v1-JSON (Kompression + kein Pretty-Print + binäre Blobs).
+2. Restore auf frischem Gerät (eingeloggt) → alle Einträge, Medien abspielbar, Crew/Vessel-Selection vorhanden.
+3. Falsches Passphrase → `BACKUP_WRONG_PASSPHRASE` (wie heute).
+4. Beschädigtes ZIP / fehlende Manifest → `BACKUP_INVALID_FORMAT`.
+5. v1-Datei (`version: 1`) → `BACKUP_VERSION_UNSUPPORTED` mit Hinweis.
+
+---
+
+## 2. Container: ZIP-Archiv
+
+| Eigenschaft | Wert |
+|-------------|------|
+| MIME-Typ (Download) | `application/vnd.kapteins-daagbok+zip` (Fallback: `application/zip`) |
+| Dateiendung | `.daagbok` (kein `.json`) |
+| Kompression | ZIP mit DEFLATE (Level 6 — Balance Größe/Geschwindigkeit) |
+| Magic / Erkennung | ZIP-Signatur `PK\x03\x04` + `manifest.json` mit `format` + `version: 2` |
+
+**Bibliothek (Client):** [`fflate`](https://github.com/101arrowz/fflate) (klein, ESM, ZIP sync/async). Als direkte `dependencies`-Eintrag in `client/package.json`, nicht nur transitiv.
+
+**Warum ZIP und nicht nur gzip auf einer JSON-Datei?**
+
+- Viele unabhängige Blobs → paralleles Entpacken, Preview ohne alle Medien zu lesen.
+- Manifest bleibt klein (< 100 KB typisch).
+- Standard-Tooling (optional manuelle Inspektion mit `unzip -l`).

+    "gpsTracks": [ … ],
+    "nmeaArchives": [ … ]
+  }
+}
+```
+
+- **`appVersion`:** optional, aus Client-Build (PWA-Version) — nur für Support/Debug.
+- **`totalUncompressedBytes`:** Summe der Blob-Größen vor ZIP — für UI („~120 MB“) und Speicher-Warnung vor Import.
+- **Keine** `encryptedData` / IV / Tag im Manifest für große Blobs — nur im Binärformat (siehe 3.2).
+
+### 3.2 Binärformat `.enc` (einheitlich für alle Payloads)
+
+Jede `.enc`-Datei ist **roh**, kein JSON:
+
+```
+Offset  Size     Inhalt
+0       4        Magic ASCII "KDAB" (Kaptein's Daagbok)
+4       1        Format version = 1
+5       12       IV (AES-GCM, wie heute)
+17      16       Auth tag (AES-GCM)
+33      N        Ciphertext (identisch mit heutigem decryptJson-Eingang:
+                  Base64-decode von encryptedData + concat mit tag in decryptBuffer)
+```
+
+**Migration von Dexie:** Beim Export aus `encryptedData` (Base64-String) + `iv` + `tag` (Base64) → einmal decodieren → `.enc`-Datei schreiben. Beim Import umgekehrt → Dexie-Felder wie heute.
+
+Vorteil: ~33 % weniger Speicher als Base64-in-JSON; Parser liest nur Header + Länge.
+
+**`key.enc`:** Gleiches Binärformat, Inhalt = `encryptBuffer(logbookKey, passphraseDerivedKey)` — ersetzt das JSON-Objekt `logbookKey: { ciphertext, iv, tag }` aus v1.
+
+**`logbook.meta.json`:** Unverändert kleines JSON (nur `encryptedTitle`, `updatedAt`, `isDemo`) — kein Binärbedarf.
+
+### 3.3 Optionale Sidecars (Phase 2, nicht blocking v2)
+
+Für Photos/Voice-Memos könnte `{id}.meta.json` nur `{ entryId, updatedAt }` enthalten, falls das Manifest zu groß wird (>10k Medien). v2 startet mit **allen Metadaten im Manifest** — ausreichend bis ~einige tausend Dateien.
+
+---
+
+## 4. Kryptographie (unverändert in der Semantik)
+
+| Element | v1 | v2 |
+|---------|----|----|
+| Logbuch-Key im Backup | PBKDF2 + AES-GCM (`KapteinsDaagbokBackupFileSalt_v1`) | **Gleich** (Salt-String beibehalten für gleiche Passphrase → gleicher Key) |
+| Payload-Verschlüsselung | `encryptJson` mit Logbuch-Key | **Byte-für-byte gleicher Ciphertext** in `.enc` |
+| Passphrase-Mindestlänge | 8 Zeichen | 8 Zeichen |
+
+Optional in v2.1 (nicht v2): PBKDF2-Iterationen erhöhen (z. B. 310_000) mit neuem Salt `…_v2` und Feld `keyWrap: "pbkdf2-v2"` in Manifest — nur wenn gewünscht.

+  Svc->>ZIP: manifest.json + key.enc + logbook.meta.json
+  Svc->>UI: Blob + filename.daagbok
+```
+
+### Implementierungsdetails
+
+1. **Pre-sync:** wie heute `syncLogbook(logbookId)` wenn online.
+2. **Sammlung:** `collectLogbookPayloadsV2()` — alle Tabellen aus Abschnitt B-01; Batches à 20 für Medien.
+3. **ZIP-Erzeugung:** `fflate` `zipSync` oder `zip` mit Streaming-Callback; **nicht** das gesamte Archiv als ein Array im RAM, wenn `totalUncompressedBytes > 80_000_000` → Warnung in UI + ggf. `requestIdleCallback` zwischen Blobs.
+4. **Fortschritt:** `onProgress({ phase, current, total, bytes })`.
+5. **Download:** `downloadBackupBlob(blob, `${safeTitle}-${date}.daagbok`)`.
+
+### Speicher-Richtwerte (UI-Warnung)
+
+| Uncompressed | Empfehlung |
+|--------------|------------|
+| < 50 MB | Normal exportieren |
+| 50–150 MB | Hinweis: Import kann auf schwachen Geräten dauern |
+| > 150 MB | Bestätigungsdialog; Export trotzdem erlauben |
+
+ZIP reduziert typisch Medien-Anteil um **20–40 %** (JPEG/WebM komprimieren schlecht in ZIP, aber Base64-Overhead entfällt).
+
+---
+
+## 6. Ablauf Import / Preview
+
+### Preview (Passphrase-Check)
+
+1. ZIP öffnen (nur zentrales Directory lesen — `fflate` `unzip`).
+2. `manifest.json` parsen → `version === 2` prüfen.
+3. `key.enc` laden → Passphrase → Logbuch-Key.
+4. `logbook.meta.json` → Titel entschlüsseln.
+5. Counts aus Manifest anzeigen — **keine** Medien-Blobs dekodieren.
+
+### Restore
+
+1. Vollständig entpacken in **temporäre Struktur** (Object-URLs / `Map<path, Uint8Array>`) — bei >150 MB Warnung.
+2. `writeBackupToDexieV2()` — analog v1, aber aus `.enc` Bytes.
+3. `queueRestoredLogbookForSync()` — unveränderte Sync-Queue-Semantik.
+4. `listCache` auf Entries: nach Restore optional aus Entry-Payload neu ableiten (wie bei normalem Decrypt) oder beim Export mit speichern — **Design:** listCache beim Export **nicht** sichern (bleibt abgeleitetes Feld); nach Restore beim ersten Öffnen neu berechnen.
+
+### Fehlercodes (neu/angepasst)
+
+| Code | Bedeutung |
+|------|-----------|
+| `BACKUP_VERSION_UNSUPPORTED` | `version !== 2` (inkl. v1) |
+| `BACKUP_INVALID_ARCHIVE` | Kein ZIP / kein manifest |
+| `BACKUP_MISSING_BLOB` | Index verweist auf fehlende Datei |
+| `BACKUP_INVALID_ENC` | Magic/ Länge ungültig |
+| *(bestehend)* | `BACKUP_WRONG_PASSPHRASE`, `BACKUP_ID_CONFLICT`, … |
+

+
+## 7. Code-Struktur (Implementierung)

+
+**v1 entfernen:** `BACKUP_VERSION = 1`, `LogbookBackupFile`-Monolith, `JSON.stringify(…, null, 2)`, `normalizeBackupPayloads` für voiceMemos — löschen, nicht parallel halten.
+
+---
+
+## 8. Vergleich v1 → v2
+
+| Aspekt | v1 | v2 |
+|--------|----|----|
+| Container | Eine JSON-Datei | ZIP `.daagbok` |
+| Medien im Export | Base64 in JSON-Strings | Binäre `.enc`-Dateien |
+| Manifest | Alles in einem Objekt | Schlankes `manifest.json` + Blobs |
+| Kompression | Keine (+ Pretty-Print) | DEFLATE |
+| RAM Import | `file.text()` + full parse | ZIP directory + gezieltes Entpacken; Preview nur Manifest |
+| Fehlende Payloads | Kein crew/vessel selection, kein NMEA | Vollständig |
+| Abwärtskompatibel | — | Nein (bewusst) |
+
+### Größenbeispiel (Schätzung)
+
+100 Fotos à ~250 KB verschlüsselt (≈190 KB Ciphertext):
+
+- **v1 JSON:** ~100 × (190 KB × 4/3 Base64) ≈ **25 MB** nur Fotos-Ciphertext-Strings + JSON-Escaping + Pretty-Print → oft **35+ MB**
+- **v2 ZIP:** ~100 × 190 KB + Kompression ≈ **19–22 MB** Archiv
+
+---
+
+## 9. Implementierungsplan (Phasen)
+
+### Phase 1 — Kern (MVP v2)
+
+- [x] `encBlob` + `manifest` + `zipArchive` Module
+- [x] Export/Import/Preview/Restore auf v2
+- [x] Alle Dexie-Tabellen inkl. crew/vessel selection + nmeaArchives
+- [x] UI: `.daagbok`, Fehler `BACKUP_VERSION_UNSUPPORTED` für v1-JSON
+- [x] Tests: `encBlob` unit tests
+
+### Phase 2 — UX & Robustheit
+
+- [x] Export-Fortschritt
+- [x] Größen-Warnung vor Import (>150 MB)
+- [ ] `onProgress` während Restore
+
+### Phase 3 — Optional
+
+- [ ] Streaming-Export für sehr große Archive (fflate async + Chunk-Schreiben)
+- [ ] PBKDF2 v2 mit höheren Iterationen
+- [ ] Sidecar-Metadaten wenn Manifest > 2 MB
+
+---
+
+## 10. Testplan
+
+| Test | Typ |
+|------|-----|
+| `encBlob`: round-trip Dexie-Felder ↔ Bytes | Unit |
+| Manifest-Validator: version 2, fehlende paths | Unit |
+| Export → unzip → Manifest-Counts = DB-Counts | Integration (Vitest + IndexedDB fake) |
+| Restore → decrypt photo/voice → gültige Data-URL | Integration |
+| v1-JSON-Datei → `BACKUP_VERSION_UNSUPPORTED` | Unit |
+| Korruptes ZIP → `BACKUP_INVALID_ARCHIVE` | Unit |
+
+---
+
+## 11. Dokumentation & Analytics
+
+- Nutzer-Texte: „Sicherungsdatei `.daagbok`“ statt `.daagbok.json`.
+- Plausible **Backup Exported / Restored:** Properties `bytes`, `photos`, `voiceMemos` (Anzahlen, keine Inhalte).
+- Deployment: **kein Server-Change** — Backup ist rein clientseitig.
+
+---
+
+## 12. Offene Punkte (für Review)
+
+1. **Schwellwert Speicher-Warnung:** 150 MB uncompressed — anpassen nach ersten Real-Logbüchern?
+2. **NMEA-Archive:** oft groß — eigenes Subdirectory ausreichend; später ggf. „NMEA nicht ins Backup“ als Opt-out?
+3. **Geteilte Logbücher (`isShared === 1`):** Export weiterhin nur Owner — unverändert.
