 - **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.
