-## Build & Run Commands
-
-| Command | Purpose |
-|---------|---------|
-| `npm run build` | Compile TypeScript (`tsc` → `dist/`) |
-| `npm start` | Build + launch Electron app |
-| `npm run test:unit` | Vitest Unit-Tests (`src/**/*.test.ts`) |
-| `npm run test:unit:watch` | Vitest Watch-Mode |
-| `npm run test:e2e:update-logic` | Unit test for version comparison logic (fast, no Playwright) |
-| `npm run test:e2e` | Basic Playwright smoke test |
-| `npm run test:e2e:guide` | Template guide smoke test |
-| `npm run test:e2e:full` | Full end-to-end test suite |
-| `npm run test:e2e:release` | Full pre-release verification (build + unit + update-logic + 3 Playwright-Stages) |
-| `npm run dist:win` | Run all tests then build Windows NSIS installer |
-| `npm run release:gitea` | Upload release assets to Gitea (requires `GITEA_TOKEN` env var) |
-
-## Architecture
-
-**Electron app** (TypeScript, no UI framework — vanilla HTML/CSS/JS in renderer).
-
-### Process Model
-
-- **Main process** (`src/main.ts`, ~7300 lines): Core logic — Twitch API, download queue, streamlink/ffmpeg orchestration, config persistence, auto-updater, caching
-- **Preload** (`src/preload.ts`): Context bridge exposing a controlled `window.api` IPC surface
-- **Renderer** (`src/renderer*.ts`): UI split across multiple files by concern (queue, settings, updates, streamers, localization)
-- **Extrahierte Module** (`src/main/`): v5-Architektur-Umbau im Gang. Reine Helpers bereits ausgelagert nach `src/main/infra/` (fs-atomic, duration) und `src/main/domain/` (update-version-utils, i18n-backend, config-normalize). Roadmap fuer den vollstaendigen Split: `tasks/v5.0.0-roadmap.md`.
-
-### Key Patterns
-
-- **IPC via context bridge only** — all main↔renderer communication goes through `preload.ts`. Never use `ipcRenderer` directly.
-- **State**: Global variables in both processes. Main process is source of truth; renderer syncs via IPC events.
-- **Persistence**: JSON files in `C:\ProgramData\Twitch_VOD_Manager\` (config, queue, debug log) bleiben Source-of-Truth. Config auto-saves with debounce. Seit v5.0.0-alpha.1 spiegelt der Migrator (`src/main/domain/migrator.ts`) Konfiguration, Queue, downloaded_vod_ids und Streamer-Listen einmalig nach `app.db` (SQLite, better-sqlite3). Schema: `src/main/infra/schema-v5.ts`. Cutover (SQLite wird Master) in spaeterem Plan.
-- **Queue sync throttling**: Adaptive refresh rates based on window visibility (900ms active → 9000ms hidden).
-- **Caching**: Multi-tier in-memory caches (user IDs, VOD lists, clip info) with configurable TTL and periodic cleanup.
-- **Error classification**: Errors categorized as network/rate_limit/auth/tooling/integrity/io/validation/unknown with retry scheduling.
-- **Secrets**: OAuth-Token (Twitch + spaeter) landen verschluesselt via Electron `safeStorage` (Win Credential Manager) in `oauth_accounts` Tabelle der SQLite. Zugriff ueber `src/main/domain/token-store.ts`. Memory-Impl fuer Tests.
-- **Smart-Resume**: HLS-Chunk-sha1-Hashes koennen in `chunk_index` Tabelle protokolliert werden (`src/main/domain/chunk-index-store.ts`, `src/main/infra/chunk-hash.ts`). Vorbereitung fuer Crash-Recovery + Integrity-Check; Integration in Live-Recorder folgt post-5.0.
-- **OAuth (Twitch)**: Authorization Code Flow + PKCE via System-Browser + Loopback (127.0.0.1:PORT). Module: `src/main/domain/{pkce,twitch-oauth}.ts`, `src/main/infra/loopback-server.ts`. IPC-Handler + Renderer-Button + Client-ID-Config in 5.1.x — Module sind in 5.0.0 scaffold-complete, brauchen lediglich Twitch-Dev-App-Registration.
-- **Localization**: EN (`renderer-locale-en.ts`) and DE (`renderer-locale-de.ts`) string tables.
-
-### External Tools
-
-Downloads depend on **streamlink** and **ffmpeg** being available. The app caches their paths with 10-second TTL.
-
-## Release Process
-
-Documented in `README_AI_RELEASE.md`. Key points:
-- Hosted on Gitea at `git.24-music.de`
-- Auto-updater requires 3 assets per release: `.exe`, `.exe.blockmap`, `latest.yml`
-- Version set via `npm version X.Y.Z --no-git-tag-version`, commit as `release: X.Y.Z`, tag as `vX.Y.Z`
-- Never commit tokens; use `$env:GITEA_TOKEN` in PowerShell
-
-## TypeScript Config
-
-- Target: ES2022, strict mode enabled
-- Source in `src/`, compiled to `dist/`
-- No linter configured — TypeScript strict mode is the primary safety net

- *   Token:     https://id.twitch.tv/oauth2/token
- *   Validate:  https://id.twitch.tv/oauth2/validate
- *   Helix /users (whoami): https://api.twitch.tv/helix/users

- * Flow:
- *   1. startLoginFlow({clientId, scopes}) → { authUrl, ... }
- *   2. shell.openExternal(authUrl) im Caller (main.ts hat shell)
- *   3. await completeLoginFlow(state) → wartet auf Loopback-Redirect
- *   4. Exchange code+verifier gegen token via fetch
- *   5. Helix /users mit Bearer-Token → twitch_user_id + login + display_name
- *
- * Plan 03b liefert NUR Module + Tests. Eigentlicher login-flow IPC handler
- * + Renderer-Button kommt in Folgeplan, weil das Twitch-Account-Setup
- * (Client-ID in Twitch Dev Console mit korrektem Redirect-URI) erst

-# Twitch VOD Manager — v5.0.0 Goal
-
-**Baseline:** v4.6.155 (Stand 2026-05-11)
-**Target:** v5.0.0
-**Status:** Draft / nicht freigegeben
-**Sprache:** Deutsch (Stack-Begriffe englisch)
-
----
-
-## 1. Executive Summary
-
-Nach 155 Patches im 4.6er-Zyklus ist das Produkt poliert, aber im Kern unverändert seit 4.0: monolithische `main.ts` (~3700 Zeilen), JSON-File-Persistenz, Vanilla-DOM-Renderer, kein Live-Recording, keine sub-only Unterstützung, keine Tests jenseits Playwright-Smoke.
-
-**v5.0.0 ist der Bruch:** Aufnahme statt nur Download, SQLite statt JSON, modulare Domain-Architektur, Twitch-OAuth, optionales Web-Worker-Offloading für grosse Listen. Sieben Feature-Pillars, drei harte Breaking Changes, klarer Migrationspfad von 4.6.x.
-
-**Was 5.0.0 NICHT ist:** kein React/Vue-Rewrite, kein Plattform-Hop (bleibt Electron + Win), kein neues Bezahlmodell. Es bleibt der gleiche Single-User-Desktop-Client — nur deutlich erwachsener.
-
----
-
-## 2. Why Major Bump?
-
-Ein Major-Sprung ist gerechtfertigt, wenn **mindestens zwei** Kriterien erfuellt sind:
-
-| Kriterium | 5.0.0 trifft zu? | Belege |
-|---|---|---|
-| Breaking Change im Config-/Datenformat | Ja | JSON → SQLite Migration, Schema v4 → v5 |
-| Neues Kern-Feature (nicht Inkrement) | Ja | Live-Stream-Recording (sub-only via OAuth), Scheduled-Recording |
-| Architektur-Bruch | Ja | main.ts Split in 6+ Domain-Module |
-| Min-OS-/Runtime-Bump | Ja | Electron 28 → 32, Node 18 → 22, Drop Win < 10 1809 |
-| User-spuerbare UI-Verschiebung | Ja | Virtual-List, Mini-Player, Theme-Engine |
-
----
-
-## 3. Themes & Vision
-
-Drei Leitthemen ueber allen Features:
-
-### 3.1 Vom Downloader zum Recorder
-v4 reagiert: VOD existiert auf Twitch → wir laden runter. v5 agiert proaktiv: Stream geht live → wir nehmen direkt mit. Damit fallen Sub-Only-VODs (oft 60 Tage Retention), 7-Tage-Standard-Retention und geloeschte VODs als Verlust-Szenarien weg.
-
-### 3.2 Vom Tool zur Platform
-Domain-Module mit klaren Schnittstellen statt einem 3700-Zeilen-Monolith. Optionaler Plugin-Hook fuer Post-Download-Actions (z. B. Auto-Upload-Skript, Custom-Rename, Notify-Discord). Spaeter wartbar, leichter testbar.
-
-### 3.3 Vom Hobby zum stabilen Daily-Driver
-SQLite + Crash-Recovery + Chunk-Hashing + echte Unit-Tests. Wer 500 VODs queued, soll nicht in JSON-Lock-Konflikte laufen oder beim Crash 4 Stunden Download verlieren.
-
----
-
-## 4. Feature-Pillars
-
-### Pillar 1 — Live Stream Recording (P0)
-
-**Was:** App kann laufende Streams in Echtzeit mitschneiden, nicht nur VODs post-hoc downloaden.
-
-**Warum:** Sub-only Streams haben oft keine VOD-Retention oder Sub-only-VODs werden nach 60 Tagen geloescht. Recording ist der einzige Weg, sie dauerhaft zu sichern.
-
-**Scope:**
-- Streamlink-basierte Aufnahme aktiver Live-Streams (Quality-Selector wie bei VODs)
-- Auto-Start: "wenn Streamer X live geht, Recording starten" (Polling-Intervall pro Streamer konfigurierbar, default 60s)
-- Auto-Stop bei Stream-Ende + Final-Mux mit ffmpeg
-- Resume bei Mid-Stream-Disconnect (neuer HLS-Segment-Pointer, append-Mode)
-- Sub-only Streams: nutzt OAuth-Token aus Pillar 2
-
-**Acceptance:**
-- 4-Stunden-Test-Stream wird ohne Datenverlust aufgenommen
-- Disconnect-Wiederherstellung in < 15s
-- File-Output ist mux-fertig MP4 (kein .ts-Reste, kein orphan-Index)
-- UI zeigt "LIVE REC" Badge + Recording-Dauer im Streamer-Eintrag
-
-### Pillar 2 — Twitch-OAuth (Device Code Flow) (P0)
-
-**Was:** Native Anmeldung mit Twitch-Account, OAuth-Token wird verschluesselt in OS-Keychain (Win Credential Manager) gespeichert.
-
-**Warum:** Sub-only Inhalte, hoehere Rate-Limits (Helix mit User-Token > App-Token in vielen Endpoints), private Follow-Liste fuer Auto-Discovery, korrekte Mature-Content-Gating-Behandlung.
-
-**Scope:**
-- Device Code Flow (kein Browser-Embed, kein localhost-Callback noetig — sauberer fuer Desktop)
-- Multi-Account: bis zu 3 parallele Accounts (Haupt, Alt, Auto-Sub)
-- Token-Refresh automatisch, Fail-Soft auf App-Token
-- Settings-Tab "Accounts" mit Liste, Login/Logout, "Default fuer Recording"
-
-**Acceptance:**
-- Login dauert < 60s vom Klick bis Token in Keychain
-- Sub-only Test-Channel laesst sich aufnehmen mit eingeloggtem Sub-Account
-- Logout entfernt Token sauber aus Keychain (audit per Tool: kein orphan-Entry)
-
-### Pillar 3 — SQLite-Migration (P0, Breaking)
-
-**Was:** Alle App-Daten (Queue, Stats, Archiv-Index, Streamer-Liste, Recording-History) wandern von JSON-Files nach `app.db` (better-sqlite3 oder besser-im-Bundle-Alternative).
-
-**Warum:** JSON wird ab ~1000 VODs spuerbar lahm (Full-File-Rewrite bei jedem Save). SQLite gibt indexed lookups, atomic transactions, kein Lock-Konflikt bei parallelen Writes, einfache Migrationen.
-
-**Scope:**
-- Schema v5 mit Tabellen: `queue`, `archive`, `streamers`, `recordings`, `stats_daily`, `clip_index`, `config_blob`
-- Migrator-Script: liest alle `C:\ProgramData\Twitch_VOD_Manager\*.json` und schreibt in `app.db`
-- Backup vor Migration: `.json` → `.json.v4-backup`
-- Read-Path bleibt API-kompatibel fuer Renderer (IPC-Surface unveraendert)
-- WAL-Mode + busy-timeout 5000ms
-
-**Acceptance:**
-- Migrator laeuft idempotent (zweimal aufrufen = gleicher Endzustand, kein Daten-Duplikat)
-- Failure-Rollback: bei Migrator-Crash bleibt App auf JSON, kein Daten-Verlust
-- Query "alle VODs eines Streamers" < 50ms bei 10k Archiv-Eintraegen (gemessen)
-
-### Pillar 4 — Architektur-Refactor: main.ts Split (P1)
-
-**Was:** `main.ts` (3700 LoC) wird in Domain-Module zerlegt.
-
-**Ziel-Struktur:**
-```
-src/main/
-  index.ts              Entry, app lifecycle, BrowserWindow
-  domain/
-    twitch-api.ts       Helix + GraphQL Calls, Rate-Limit-Handling
-    downloader.ts       Streamlink/ffmpeg Orchestration (VOD + Live)
-    recorder.ts         Live-Stream-Recording (NEU)
-    queue.ts            Queue-State-Machine, persistence-call
-    config.ts           Settings-Schema, defaults, validation
-    auth.ts             OAuth, Token-Storage, Keychain (NEU)
-    cache.ts            In-Memory-TTL-Caches
-    updater.ts          electron-updater Wrapper
-  infra/
-    db.ts               SQLite-Wrapper, prepared statements
-    logger.ts           Strukturiertes Logging (JSON-Lines)
-    ipc.ts              Channel-Registry, type-safe Handler
-  ipc-bridge.ts         exportiert nur die API-Surface fuer preload.ts
-```
-
-**Constraint:** Renderer-IPC-Surface bleibt rueckwaertskompatibel — kein Renderer-Rewrite noetig.
-
-**Acceptance:**
-- Kein Modul groesser als 800 LoC
-- Zyklische Imports = 0 (`madge --circular` oder aequivalent)
-- E2E-Tests gruen ohne Anpassung
-
-### Pillar 5 — UI Power-Features (P1)
-
-**Was:** Renderer-seitige Spruenge, die User direkt sehen.
-
-**Scope:**
-- **Virtualized List** fuer Queue/Archive (react-window-aequivalent vanilla, oder `@tanstack/virtual-core` vanilla-Adapter) — 10k Eintraege ohne Lag
-- **Mini-Player Panel**: HLS-Stream in App-eigenem `<video>` (hls.js), kollabierbar, fuer Recording-Live-Preview + VOD-Vorschau
-- **Theme-Engine**: drei eingebaute Themes (Default, Dark High-Contrast, Light) + Custom-CSS-Slot mit Live-Reload
-- **Template-Preview live**: Title-Template aendert sich, Beispiel-Output rendert in Echtzeit unter dem Input
-- **Drag-Reorder** in Queue (HTML5-DnD, persistiert Position-Index in DB)
-- **Command-Palette** (Ctrl+K): Schnellaktionen, Streamer-Suche, Settings-Jump
-
-**Acceptance:**
-- Scroll-Performance bei 5000 Eintraegen: 60fps (Chrome DevTools Performance-Trace)
-- Theme-Switch ohne Reload
-- Command-Palette < 100ms First-Result-Latency
-
-### Pillar 6 — Smart-Resume & Integrity (P1)
-
-**Was:** Downloads/Recordings ueberleben Crash, Disconnect, Reboot.
-
-**Scope:**
-- Jeder HLS-Segment-Chunk bekommt sha1, geschrieben in DB-Tabelle `chunk_index`
-- Bei Resume: vergleicht local-chunk-hash mit Manifest, ueberspringt valide Chunks, faengt am ersten Mismatch an
-- Crash-Recovery beim Startup: scannt `recordings`-Tabelle nach `state=running` und bietet Resume-Dialog an
-- Final-Integrity-Check: ffprobe-Aufruf auf fertige Datei, schreibt `verified=1` in DB
-
-**Acceptance:**
-- App-Kill mid-download → Neustart → Resume genau ab Abbruch-Chunk (manueller Test)
-- Korrupte Chunk-Datei wird erkannt und neu geladen (per Mutation-Test: zufaelliges Byte flippen)
-
-### Pillar 7 — Scheduled Recording & Auto-Discovery (P2)
-
-**Was:** Automatisierungs-Layer ueber Pillar 1+2.
-
-**Scope:**
-- Pro Streamer: "Auto-Record on Live: ja/nein" + Quality-Preset
-- Zeit-Plan: "nur zwischen 18-02 Uhr aufnehmen" (vermeidet Reruns/Marathons)
-- **Top-Clip-Crawler**: pro Streamer alle X Tage die N besten Clips (Helix `/clips`) downloaden
-- **Follow-Sync**: importiert eingeloggte Follow-Liste als Streamer-Eintraege (opt-in)
-
-**Acceptance:**
-- 3-Streamer-Auto-Record-Test ueber 24h ohne Eingriff, kein Doppelaufnahme bei Stream-Reconnect
-

-## 5. Breaking Changes
-
-| # | Was bricht | Migration | User-Impact |
-|---|---|---|---|
-| BC-1 | Config-Speicherort | Migrator on first 5.0 start, `.v4-backup` der JSONs bleibt liegen | Einmalig 5-30s Migrations-Dialog |
-| BC-2 | Min-Windows: Win10 1809 (Oktober 2018) | Installer-Check, blockiert Setup auf alten OS | Sehr wenige User betroffen |
-| BC-3 | Node-API-Version: Plugins die auf Node 18 N-API gebaut sind muessen rebuild (relevant fuer better-sqlite3, evtl. fsevents) | Pre-built Binaries im Bundle | Transparent fuer User |
-| BC-4 | Streamer-Eintrag-Format aendert sich (neue Felder: `oauth_account_id`, `auto_record`, `record_quality`) | Auto-Default bei Migration | Transparent |
-| BC-5 | Auto-Updater Channel: alte 4.x-Clients sehen 5.0 nicht im stable-Channel, sondern in `next` (opt-in) | User muss bewusst Channel wechseln; nach 4 Wochen Beta: 5.0 → stable | Bewusste User-Aktion |
-
----
-
-## 6. Tech-Stack Upgrades
-
-| Komponente | 4.6 | 5.0 | Grund |
-|---|---|---|---|
-| Electron | 28.x | 32.x (oder LTS aktuell) | Security-Patches, Chromium-Upgrade |
-| Node | 18 | 22 | LTS, V8 perf |
-| TypeScript | 5.3 | 5.6+ | satisfies / decorators stable |
-| ESLint | 10 | aktueller flat-config | passt |
-| Neu: better-sqlite3 | — | latest | SQLite-Persistenz |
-| Neu: hls.js | — | latest | Mini-Player |
-| Neu: keytar (oder Electron safeStorage) | — | latest | OAuth-Token-Storage |
-| Playwright | 1.59 | aktuell | E2E |
-| Neu: vitest | — | latest | Unit-Tests |
-
----
-
-## 7. Quality & DevX
-
-- **Unit-Tests (Vitest):** mind. 60% Coverage in `src/main/domain/*` zum 5.0.0-GA. Reine Logik-Tests, kein Electron-Boot.
-- **E2E (Playwright):** bestehende Suite plus drei neue Szenarien (Login, Live-Record-Start, SQLite-Migration).
-- **CI:** weiterhin lokal (Solo-Projekt), aber `npm run check:all` = build + lint + vitest + e2e in einem Skript.
-- **Logging:** strukturiert JSONL in `logs/app-YYYY-MM-DD.jsonl`, 14-Tage-Retention, mit Level (debug/info/warn/error) und Trace-IDs pro Download/Recording.
-- **Crash-Reports:** opt-in Sentry (oder einfacher: lokaler Crash-Log-Export + Copy-to-Clipboard-Button). Default: aus, kein Telemetrie-Surprise.
-

-
-## 8. Release-Phasen
-
-| Phase | Version | Was rein | Wann (relativ) |
-|---|---|---|---|
-| Alpha-1 | 5.0.0-alpha.1 | SQLite-Migrator + Architektur-Split | T+0 |
-| Alpha-2 | 5.0.0-alpha.2 | OAuth + Live-Recording (Baseline) | T+2 Wo |
-| Beta-1 | 5.0.0-beta.1 | UI Power-Features, Smart-Resume | T+4 Wo |
-| Beta-2 | 5.0.0-beta.2 | Scheduled/Auto-Discovery, Bug-Fixes | T+6 Wo |
-| RC | 5.0.0-rc.1 | nur noch Bugfixes, kein Feature-Add | T+8 Wo |
-| GA | 5.0.0 | Public, `next`-Channel → `stable` | T+10 Wo |
-
-Konkret Daten setze ich nicht — die haengen davon ab, wie eng du das fahren willst.
-
----
-
-## 9. Out-of-Scope (bewusst NICHT in 5.0.0)
-
-- React/Vue/Svelte-Rewrite des Renderers (Risiko zu gross, Vanilla bleibt)
-- macOS/Linux-Builds (Electron-Builder kann, aber kein Test-Setup → erst 5.1+)
-- Cloud-Sync (Queue/Settings ueber Geraete) — eigener Major-Bump waert
-- Chat-Recording / Chat-Renderer (TwitchDownloaderCLI Integration) — verlockend, aber Scope-Creep → 5.1
-- Mobile-Companion-App
-- Plugin-API fuer Dritte (Hooks koennen wir intern bauen, aber kein public-API-Versprechen in 5.0)
-- AI-Highlight-Detection (lokales LLM) — Forschung, kein Produkt-Feature 2026
-
----
-
-## 10. Definition of Done (5.0.0 GA)
-
-Alle Punkte erfuellt:
-
-1. [ ] Pillars 1-6 implementiert und in E2E-Tests abgedeckt (Pillar 7 darf teilweise sein, mind. Auto-Record-on-Live)
-2. [ ] SQLite-Migrator getestet auf realer 4.6-Installation mit 5k+ Archive-Eintraegen, idempotent, mit Rollback-Path
-3. [ ] OAuth-Token landet in Keychain, audit zeigt sauberen Logout
-4. [ ] Vitest-Coverage `src/main/domain` >= 60%
-5. [ ] Playwright-Suite gruen, inkl. drei neue Szenarien
-6. [ ] Mini-Player + Theme-Engine + Virtual-List manuell verifiziert (Demo-Video)
-7. [ ] Auto-Updater: bestehende 4.6-Installation kriegt 5.0 ueber `next`-Channel, Migration laeuft, App startet
-8. [ ] README + CLAUDE.md aktualisiert (neue Architektur, neue Commands, neue Settings)
-9. [ ] CHANGELOG-Eintrag mit allen Breaking Changes prominent oben
-10. [ ] Frische Installation aus `Twitch-VOD-Manager-Setup-5.0.0.exe` auf clean Win11-VM: erstes Recording lauft binnen 5 Minuten User-Klicks
-
----
-
-## 11. Naechste Schritte (wenn du dieses Goal annimmst)
-
-1. Goal mit eigenem Realitaetscheck lesen — was streichen, was zuerst
-2. Pillar 3 (SQLite) zuerst, weil es Voraussetzung fuer 1, 6, 7 ist
-3. Branch `feat/v5-foundation` aufmachen, dort Architektur-Split + SQLite parallel
-4. Nach Alpha-1 entscheiden, ob OAuth vor UI-Refactor oder umgekehrt
-5. Eigenes `tasks/v5.0.0-checklist.md` aus Pillar-Acceptance-Criteria generieren, abhakbar

-# Plan 02: SQLite-Foundation (Pillar 3)
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** SQLite-Infrastruktur ins Projekt einbauen + Migrator, der bestehende JSON-Daten aus `C:\ProgramData\Twitch_VOD_Manager\*.json` nach `app.db` ueberfuehrt. JSON-Pfade bleiben Source-of-Truth — SQLite laeuft als Shadow-Schreibziel. Cutover (SQLite wird Master) erfolgt in einem spaeteren Plan.
-
-**Architecture:** `better-sqlite3` (sync embedded). Schema-First via Inline-Konstante (`schema-v5.ts`) damit `tsc` keine SQL-Files kopieren muss. WAL-Mode, busy_timeout 5000ms, foreign_keys ON. Migrator ist idempotent (Marker in `migrations_applied` Tabelle). Bei Crash bleibt JSON-Pfad funktionsfaehig.
-
-**Tech Stack:** better-sqlite3 + @types/better-sqlite3, vitest mit echten temp-DB-Files.
-
-**Verifikation pro Task:** `npm run build` + `npm run test:unit` gruen.
-
----
-
-## Out of Scope fuer Plan 02
-
-- Reads aus SQLite umstellen (Renderer/IPC bleibt auf JSON)
-- electron-rebuild fuer better-sqlite3 (Workaround in Plan 02, voller Pipeline-Fix in spaeterem Plan)
-- Schema-Migrationen v5 → v6
-- Sub-only-Tabellen (kommen mit OAuth in Plan 03)
-
----
-
-## File Structure
-
-**Neu:**
-- `src/main/infra/schema-v5.ts` — Schema als TypeScript-String-Konstante
-- `src/main/infra/db.ts` — better-sqlite3 Wrapper
-- `src/main/infra/db.test.ts`
-- `src/main/domain/migrator.ts` — JSON to SQLite
-- `src/main/domain/migrator.test.ts`
-
-**Modifiziert:**
-- `package.json`

-### Task 3: db.ts Wrapper + 5 Tests
-
-**Public DbHandle Interface:**
-- `run(sql, params?)` — single-statement execute
-- `get<T>(sql, params?)` — first row or undefined
-- `all<T>(sql, params?)` — alle Rows
-- `transaction<R>(fn)` — atomares Bracket
-- `runBatch(sql)` — multi-statement (intern via `_db.exec(sql)`, fuer Schema-Bootstrap)
-- `close()`
-- `raw` getter
-
-**openDatabase(filePath: string): DbHandle**
-- Erstellt File (better-sqlite3 default-Verhalten)

-### Task 4: Migrator + 8 Tests
-
-**MigratorOptions:**
-- `db: DbHandle`
-- `appDataDir: string`
-
-**MigrationResult:**
-- `alreadyApplied: boolean`
-- `configMigrated: boolean`
-- `queueMigrated: boolean`
-- `downloadedVodsCount: number`
-- `streamersCount: number`
-- `errors: MigrationError[]` (`{ source, message }`)
-
-**migrateJsonToSqlite(opts):**
-1. Check `migrations_applied` fuer `name='v4-to-v5-jsons'` → wenn vorhanden → return `alreadyApplied: true`
-2. Lies `appDataDir/config.json` falls vorhanden:
-   - Parse, in `db.transaction(() => { ... })`:
-     - Whitelisted Keys (siehe Liste unten) → `INSERT OR REPLACE INTO config_kv(key, value, updated_at) VALUES (?, ?, strftime('%s','now'))` mit `value = JSON.stringify(config[key])`
-     - `downloaded_vod_ids` (Array of String) → `INSERT OR IGNORE INTO downloaded_vods(vod_id) VALUES (?)`
-     - `auto_record_streamers` → normalizeLogin + `INSERT...ON CONFLICT DO UPDATE auto_record=1`
-     - `auto_vod_download_streamers` → normalizeLogin + `INSERT...ON CONFLICT DO UPDATE auto_vod_download=1`
-   - Bei Erfolg: `.v4-backup` Copy schreiben (`fs.copyFileSync`)
-   - Bei Fehler: error pushen, continue
-3. Lies `appDataDir/download_queue.json` falls vorhanden:
-   - Parse, fuer jedes Item (mit `id`-Feld): `INSERT OR REPLACE INTO queue_items(...) VALUES (...)`
-   - Fields: id, streamer→normalizeLogin, vod_id, clip_id, title, output_path, status (default 'pending'), progress_pct, error_message, created_at, updated_at, completed_at, payload_json=JSON.stringify(item)
-   - Bei Erfolg: `.v4-backup` Copy
-4. Schreibe Marker: `INSERT INTO migrations_applied(name, payload) VALUES ('v4-to-v5-jsons', JSON.stringify({summary}))`

-# Plan 03: OAuth Foundation (Pillar 2 — Storage-Layer)
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans.
-
-**Goal:** OAuth-Token-Speicher in SQLite + verschluesseltes Persistieren via Electron `safeStorage`. Keine eigentliche OAuth-Flow-Implementierung in Plan 03 — die kommt in einem Folgeplan (Plan 03b), nachdem die Flow-Entscheidung (Authorization Code mit PKCE via System-Browser + localhost-Redirect, oder Implicit via embedded BrowserWindow) bestaetigt ist.
-
-**Architecture:** Schema-Extension via additives `CREATE TABLE IF NOT EXISTS`. Crypto-Layer abstrahiert hinter `SecureStorage` Interface — Electron-safeStorage in Production, In-Memory in Tests. Token-CRUD ueber `token-store.ts` modul. Twitch ist der erste/einzige Provider in Plan 03 — Interface ist provider-agnostisch fuer spaeter.
-
-**Tech Stack:** Electron `safeStorage` (Win Credential Manager im Hintergrund), better-sqlite3, vitest.
-
----
-
-## Aenderung vs Goal.md
-
-Goal sagt "Device Code Flow". Twitch unterstuetzt das nicht — nur Authorization Code + PKCE, Implicit, oder Client Credentials. Plan 03 macht den Storage-Layer flow-agnostisch fertig. Konkrete Flow-Wahl + Implementation = Plan 03b (separat).
-
----
-
-## Out of Scope fuer Plan 03
-
-- Eigentliche OAuth-Flow-Implementation (Browser-Window oder System-Browser + Loopback)
-- Twitch Helix-Endpunkte mit Token (zB `/users/me`) — kommt mit Flow
-- IPC-Handler `login/logout/whoami` — kommt mit Flow
-- Renderer-UI fuer Multi-Account — kommt mit UI-Plan
-- Sub-only-Stream-Aufnahme — kommt mit Live-Rec-Plan
-
----
-
-## File Structure

-## Tasks
-
-### Task 1: Schema-Extension oauth_accounts
-
-In `schema-v5.ts` an das Ende der Tabellen-Deklarationen (vor `migrations_applied`) anhaengen:
-
-```sql
-CREATE TABLE IF NOT EXISTS oauth_accounts (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    provider TEXT NOT NULL,
-    twitch_user_id TEXT,
-    login TEXT,
-    display_name TEXT,
-    encrypted_access_token TEXT NOT NULL,
-    encrypted_refresh_token TEXT,
-    expires_at INTEGER,
-    scopes_json TEXT,
-    is_default INTEGER NOT NULL DEFAULT 0,
-    created_at INTEGER NOT NULL DEFAULT (strftime('%s','now')),
-    updated_at INTEGER NOT NULL DEFAULT (strftime('%s','now')),
-    UNIQUE(provider, twitch_user_id)
-);
-
-CREATE INDEX IF NOT EXISTS idx_oauth_provider ON oauth_accounts(provider);
-CREATE INDEX IF NOT EXISTS idx_oauth_default ON oauth_accounts(is_default);
-```
-
-- [ ] Schema-Konstante erweitern
-- [ ] db.test.ts: 1 Test adden — `oauth_accounts` Tabelle existiert nach openDatabase
-- [ ] `npm run test:unit` gruen

-
-### Task 2: secure-storage Modul + 4 Tests
-
-**Public Interface:**
-```typescript
-export interface SecureStorage {
-    isEncryptionAvailable(): boolean;
-    encrypt(plaintext: string): string;   // base64-encoded ciphertext
-    decrypt(ciphertext: string): string;
-}
-
-export class MemorySecureStorage implements SecureStorage { ... }  // for tests
-export function createElectronSecureStorage(): SecureStorage;       // requires app.whenReady fired
-```
-
-**MemoryImpl:** verschluesselt nicht, gibt plaintext unveraendert zurueck. Liefert `isEncryptionAvailable() === false`. Markiert klar im Logger, dass kein Crypto greift — fuer Tests OK.
-
-**ElectronImpl:** wrappt `electron.safeStorage`. `isEncryptionAvailable()` ruft `safeStorage.isEncryptionAvailable()`. `encrypt()` ruft `safeStorage.encryptString(plaintext)` → Buffer → base64-string. `decrypt()` inverse.
-
-**Tests** (`secure-storage.test.ts`):
-- MemoryImpl: `isEncryptionAvailable()` returns false
-- MemoryImpl: `decrypt(encrypt('hello')) === 'hello'`
-- MemoryImpl: roundtrip mit multi-byte (`'aeoeue-test'`)
-- MemoryImpl: empty string roundtrip
-- ElectronImpl: skip in vitest-env (Electron nicht verfuegbar), aber Existence-Check via `typeof createElectronSecureStorage === 'function'`

-    provider: string;
-    twitchUserId: string | null;
-    login: string | null;
-    displayName: string | null;
-    expiresAt: number | null;
-    scopes: string[];
-    isDefault: boolean;
-    createdAt: number;
-    updatedAt: number;
-}
-
-export interface TokenWriteInput {
-    provider: string;
-    twitchUserId?: string;
-    login?: string;
-    displayName?: string;
-    accessToken: string;     // plaintext, wird verschluesselt geschrieben
-    refreshToken?: string;
-    expiresAt?: number;
-    scopes?: string[];
-    isDefault?: boolean;
-}
-
-export interface TokenStore {
-    upsert(input: TokenWriteInput): TokenRecord;
-    list(provider?: string): TokenRecord[];
-    getDefault(provider: string): TokenRecord | null;
-    setDefault(id: number): void;
-    getAccessToken(id: number): string;   // entschluesselt
-    getRefreshToken(id: number): string | null;
-    delete(id: number): void;
-}
-
-export function createTokenStore(db: DbHandle, storage: SecureStorage): TokenStore;
-```
-
-**Tests (mit MemorySecureStorage):**
-1. `upsert` neuer Account → record returned mit id > 0
-2. `upsert` same provider + twitch_user_id → updated, kein neuer record
-3. `list()` liefert alle accounts
-4. `list('twitch')` filtert nach provider
-5. `getDefault('twitch')` liefert isDefault=1, oder null
-6. `setDefault(id)` setzt is_default=1 fuer id, 0 fuer alle anderen mit gleichem provider
-7. `getAccessToken` entschluesselt korrekt
-8. `delete` entfernt record
-
-(Mind. 6 Tests — gerne mehr.)

-- `src/main/infra/chunk-hash.test.ts`
-- `src/main/domain/chunk-index-store.ts` — CRUD auf chunk_index
-- `src/main/domain/chunk-index-store.test.ts`
-
-**Modifiziert:**
-- `src/main/infra/schema-v5.ts` — neue Tabelle `chunk_index`
-- `src/main/infra/db.test.ts` — 1 Test fuer neue Tabelle
-- `CLAUDE.md`
-- `tasks/v5.0.0-roadmap.md`

-## Tasks
-
-### Task 1: Schema-Extension chunk_index
-
-In schema-v5.ts vor `migrations_applied`:
-
-```sql
-CREATE TABLE IF NOT EXISTS chunk_index (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    item_id TEXT NOT NULL,
-    chunk_seq INTEGER NOT NULL,
-    sha1_hex TEXT NOT NULL,
-    bytes INTEGER NOT NULL,
-    created_at INTEGER NOT NULL DEFAULT (strftime('%s','now')),
-    UNIQUE(item_id, chunk_seq)
-);
-
-CREATE INDEX IF NOT EXISTS idx_chunk_item ON chunk_index(item_id);
-CREATE INDEX IF NOT EXISTS idx_chunk_sha1 ON chunk_index(sha1_hex);
-```
-
-- [ ] Schema-Konstante erweitern
-- [ ] db.test.ts: 1 neuer Test fuer chunk_index
-- [ ] Commit: `feat(db): add chunk_index table (sha1 of recorded HLS segments)`
-
----
-
-### Task 2: chunk-hash Modul
-
-**API:**
-```typescript
-export function hashBuffer(b: Buffer): string;          // sha1 hex
-export function hashFile(filePath: string): Promise<string>;  // streaming sha1
-```
-
-**Tests:**
-- known input → known sha1 (fixture: `'hello'` → `aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d`)
-- empty buffer → `da39a3ee5e6b4b0d3255bfef95601890afd80709`
-- File hash via tmp file matches buffer hash for same content
-- Large file (1MB+) hashes successfully
-
-- [ ] Tests + Modul
-- [ ] Commit: `feat(resume): chunk-hash sha1 helpers (4 tests)`
-
----
-
-### Task 3: chunk-index-store Modul
-
-**API:**
-```typescript
-export interface ChunkRecord {
-    id: number;
-    itemId: string;
-    chunkSeq: number;
-    sha1Hex: string;
-    bytes: number;
-    createdAt: number;
-}
-
-export interface ChunkIndexStore {
-    record(itemId: string, chunkSeq: number, sha1Hex: string, bytes: number): ChunkRecord;
-    listForItem(itemId: string): ChunkRecord[];
-    countForItem(itemId: string): number;
-    lookupBySha1(sha1Hex: string): ChunkRecord[];
-    deleteForItem(itemId: string): number;  // returns deleted-row count
-}
-
-export function createChunkIndexStore(db: DbHandle): ChunkIndexStore;
-```
-
-**Tests (mit MemorySecureStorage NICHT noetig — kein encryption hier):**
-1. record + listForItem
-2. UNIQUE(item_id, chunk_seq) — zweimal gleicher (itemId, chunkSeq) → INSERT OR REPLACE (latest wins)
-3. countForItem
-4. lookupBySha1 (dedupe-Erkennung)
-5. deleteForItem
-6. Ordering — listForItem nach chunk_seq ASC
-7. Bytes-Roundtrip
-
-- [ ] Tests + Modul
-- [ ] Commit: `feat(resume): chunk-index-store CRUD (7 tests)`
-
----
-
-### Task 4: Full Verification + Bump 5.0.0-alpha.3
-
-- [ ] `npm run test:e2e:release` Exit 0 (unit jetzt >= 138)
-- [ ] `npm version 5.0.0-alpha.3 --no-git-tag-version`
-- [ ] Commit + Tag v5.0.0-alpha.3
-
----
-
-### Task 5: Docs
-
-CLAUDE.md "Smart-Resume" Notiz:
-> Recorded HLS-Segments koennen mit sha1-Hash in `chunk_index` Tabelle protokolliert werden (`src/main/domain/chunk-index-store.ts`). Vorbereitung fuer Crash-Recovery + Integrity-Check; eigentliche Integration in den Recorder kommt in Folgeplan.
-
-Roadmap: Plan 04 → DONE, Plan 04b "Resume Integration" als naechster Eintrag.
-
----
-
-## Done-Definition
-
-1. `chunk_index` Tabelle existiert nach openDatabase
-2. hashBuffer + hashFile getestet (known-input + roundtrip)
-3. ChunkIndexStore CRUD getestet
-4. test:e2e:release Exit 0
-5. >= 12 neue unit tests
-6. v5.0.0-alpha.3 getaggt

-# v5.0.0 Roadmap (Reality-Aligned)
-
-**Baseline:** v4.6.155
-**Spec:** `tasks/v5.0.0-goal.md`
-**Last verified:** 2026-05-11

-## Reality Check vs. Goal
-
-Beim Vergleich der echten Codebase (`src/main.ts` 7485 LoC mit 30+ Sektionen) gegen die Goal-Annahmen zeigt sich: einige "neu zu bauenden" Features existieren teilweise schon.
-
-| Pillar | Goal sagt | Reality | Restarbeit % |
-|---|---|---|---|
-| P1 — Live Stream Recording | "neu" | Auto-Record-Poller, Live-Recording-Events-Log, Live-Chat-Capture existieren | ~30% (Polish + Sub-only-Pfad nach OAuth) |
-| P2 — Twitch OAuth | "neu" | App nutzt nur public Web-Client-ID, keine User-Auth | 100% |
-| P3 — SQLite-Migration | "Breaking" | Config + Queue + Stats sind JSON-Files | 100% |
-| P4 — main.ts Split | "neu" | 7485 LoC Monolith, 30 Sektionen, schon klar getrennt | 100% (mechanische Arbeit) |
-| P5 — UI Power-Features | "neu" | Vanilla DOM, keine Virtualisierung, kein Mini-Player, ein Theme | 90% |
-| P6 — Smart-Resume | "neu" | `auto_resume_live_recording` Flag existiert, `auto_merge_resumed_parts`, Crash-Recovery rudimentaer | ~60% (Chunk-Hash + Integrity-Check fehlen) |
-| P7 — Scheduled/Auto-Discovery | "neu" | Auto-VOD-Download-Poller + Live-Status-Batch-Poller schon implementiert | ~30% (Top-Clip-Crawler, Follow-Sync fehlen) |
-
-**Konsequenz:** Reihenfolge der Plane orientiert sich am Restarbeits-Volumen und Dependencies.

-Plan 01: Foundation — Vitest + Pure-Utility-Extraction          [DONE — v5.0.0-alpha.0]
-  └─> Plan 02: SQLite-Foundation (P3)                            [DONE — v5.0.0-alpha.1]

-                 └─> DB-Singleton Lift + Plan 03b: OAuth Flow Scaffold   [DONE — v5.0.0]
-
-Post-5.0 (5.1.x):
-  Plan 04b Resume Integration (recorder hook) — touches main.ts state
-  Plan 05  Live-Rec Polish + Sub-only — needs user-supplied Twitch Client ID
-  Plan 06  UI Power (virtual list, mini-player, command palette) — renderer work
-  Plan 07-09 Architektur-Split Rest (Pillar 4) — state-strategy zuerst
-            └─> Plan 04: Live-Recording Polish + Sub-only (P1)
-                 ├─> Plan 05: Auto-Discovery Erweiterung (P7)
-                 └─> Plan 06: UI Power-Features (P5)
-                      └─> Plan 07: Smart-Resume Finalisierung (P6)
-                           └─> Plan 08: Architektur-Split Pt. 1 (state-coupled modules)
-                                └─> Plan 09: Architektur-Split Pt. 2 (final split)
-                                     └─> Plan 10: v5.0.0-rc.1 → GA
-```
-
-**Begruendung der Umordnung:** Plan 01 hat das Pure-Extraktion-Pattern validiert (Pillar 4 Teil-1).
-Weiter splitten der state-gekoppelten Module braucht zuerst eine State-Container-Strategie — das ist
-besser informiert nachdem Features (SQLite, OAuth, Live-Rec) ins System gehen und die echten
-Querverbindungen sichtbar sind. Bis dahin lebt das Pattern aus Plan 01 weiter (neue Module landen
-in `src/main/{infra,domain}/`), nur die alten in main.ts steckenden Stateful-Funktionen bleiben dort.
-
-Plan 02 = Pillar 3 (SQLite).
-Plan 03 = Pillar 2 (OAuth).
-Plan 04 = Pillar 1.
-Plan 05 = Pillar 7.
-Plan 06 = Pillar 5.
-Plan 07 = Pillar 6.
-Plan 08-09 = Pillar 4 Rest.
-Plan 10 = Release.
