-- Modernes, dunkles UI mit Header-Steuerung (Start, Pause, Stop, Speed, ETA)
+## Why this tool?
-- Tabs: **Linksammler**, **Downloads**, **Settings**
-- Paketbasierte Queue mit Datei-Status, Progress, Speed, Retries
-- Paket-Abbruch waehrend laufender Downloads inklusive sicherem Archiv-Cleanup
-- `.dlc` Import (Dateidialog und Drag-and-Drop)
-- Session-Persistenz (robustes JSON-State-Management)
-- Auto-Resume beim Start (optional)
-- Reconnect-Basislogik (429/503, Wartefenster, resumable priorisiert)
-- Integritaetscheck (SFV/CRC32/MD5/SHA1) nach Download
-- Auto-Retry bei Integritaetsfehlern
-- Cleanup-Trigger fuer fertige Tasks:
-  - Nie
-  - Sofort
-  - Beim App-Start
-  - Sobald Paket fertig ist
 
-## Voraussetzungen
+- Familiar download-manager workflow: collect links, start, pause, resume, and finish cleanly.
+- Multiple debrid providers in one app, including automatic fallback.
+- Built for stability with large queues: session persistence, reconnect handling, resume support, and integrity verification.
 
-- Node.js 20+ (empfohlen 22+)
+## Core features
-- Windows 10/11 (fuer Release-Build)
+
-- Optional: 7-Zip/UnRAR fuer RAR/7Z Entpacken
+### Queue and download engine
+
+- Package-based queue with file status, progress, ETA, speed, and retry counters.
+- Start, pause, stop, and cancel for both single items and full packages.
+- Multi-select via Ctrl+Click for batch operations on packages and items.
+- Duplicate handling when adding links: keep, skip, or overwrite.
+- Session recovery after restart, including optional auto-resume.
+- Circuit breaker with escalating backoff cooldowns to handle provider outages gracefully.
+
+### Debrid and link handling
+
+- Supported providers: `realdebrid`, `megadebrid`, `bestdebrid`, `alldebrid`.
+- Configurable provider order: primary + secondary + tertiary.
+- Optional automatic fallback to alternative providers on failures.
+- `.dlc` import via file picker and drag-and-drop.
+
+### Extraction, cleanup, and quality
+
+- JVM-based extraction backend using SevenZipJBinding + Zip4j (supports RAR, 7z, ZIP, and more).
+- Automatic fallback to legacy UnRAR/7z CLI tools when JVM is unavailable.
+- Auto-extract with separate target directory and conflict strategies.
+- Hybrid extraction: simultaneous downloading and extracting with smart I/O priority throttling.
+- Nested extraction: archives within archives are automatically extracted (one level deep).
+- Pre-extraction disk space validation to prevent incomplete extracts.
+- Right-click "Extract now" on any package with at least one completed item.
+- Post-download integrity checks (`CRC32`, `MD5`, `SHA1`) with auto-retry on failures.
+- Completed-item cleanup policy: `never`, `immediate`, `on_start`, `package_done`.
+- Optional removal of link artifacts and sample files after extraction.
+
+### Auto-rename
+
+- Automatic renaming of extracted files based on series/episode patterns.
+- Multi-episode token parsing for batch renames.
+
+### UI and progress
+
+- Visual progress bars with percentage overlay for packages and individual items.
+- Real-time bandwidth chart showing current download speeds.
+- Persistent download counters: all-time totals and per-session statistics.
+- Download history for completed packages.
+- Vertical sidebar with organized settings tabs.
+- Hoster display showing both the original source and the debrid provider used.
+
+### Convenience and automation
+
+- Clipboard watcher for automatic link detection.
+- Minimize-to-tray with tray menu controls.
+- Speed limits globally or per download.
+- Bandwidth schedules for time-based speed profiles.
+- Built-in auto-updater via `git.24-music.de` Releases.
+- Long path support (>260 characters) on Windows.
 
 ## Installation
 
+### Option A: prebuilt releases (recommended)
+
+1. Download a release from the `git.24-music.de` Releases page.
+2. Run the installer or portable build.
+3. Add your debrid tokens in Settings.
+
+Releases: `https://git.24-music.de/Administrator/real-debrid-downloader/releases`
+
+### Option B: build from source
+
+Requirements:
+
+- Node.js `20+` (recommended `22+`)
+- npm
+- Windows `10/11` (for packaging and regular desktop use)
+- Java Runtime `8+` (for SevenZipJBinding sidecar backend)
+- Optional fallback: 7-Zip/UnRAR if you force legacy extraction mode
+
 ```bash
 npm install

-## Entwicklung
-
-```bash
 npm run dev
 ```
 
-## Build
+## NPM scripts
+
+| Command | Description |
+| --- | --- |
+| `npm run dev` | Starts main process, renderer, and Electron in dev mode |
+| `npm run build` | Builds main and renderer bundles |
+| `npm run start` | Starts the app locally in production mode |
+| `npm test` | Runs Vitest unit tests |
+| `npm run self-check` | Runs integrated end-to-end self-checks |
+| `npm run release:win` | Creates Windows installer and portable build |
+| `npm run release:gitea -- <version> [notes]` | One-command version bump + build + tag + release upload to `git.24-music.de` |
+| `npm run release:codeberg -- <version> [notes]` | Legacy path for old Codeberg workflow |
+
+### One-command git.24-music release
 
 ```bash
-npm run build
+npm run release:gitea -- 1.6.31 "- Maintenance update"
 ```
 
-Danach liegen die Artefakte in:
+This command will:
 
-- `build/main`
+1. Bump `package.json` version.
-- `build/renderer`
+2. Build setup/portable artifacts (`npm run release:win`).
+3. Commit and push `main` to your `git.24-music.de` remote.
+4. Create and push tag `v<version>`.
+5. Create/update the Gitea release and upload required assets.
 
-## Start (Production lokal)
+Required once before release:
 
 ```bash
-npm run start
+git remote add gitea https://git.24-music.de/<user>/<repo>.git
 ```
 
-## Tests
+PowerShell token setup:
 
-```bash
+```powershell
-npm test
+$env:GITEA_TOKEN="<dein-token>"
-npm run self-check
 ```
 
-- `npm test`: Unit-Tests fuer Parser/Cleanup/Integrity
+## Typical workflow
-- `npm run self-check`: End-to-End-Checks mit lokalem Mock-Server (Queue, Pause/Resume, Reconnect, Paket-Cancel)
 
-## Projektstruktur
+1. Add provider tokens in Settings.
+2. Paste/import links or `.dlc` containers.
+3. Optionally set package names, target folders, extraction, and cleanup rules.
+4. Start the queue and monitor progress in the Downloads tab.
+5. Review integrity results and summary after completion.
 
-- `src/main`: Electron Main Process + Download/Queue Logik
+## Project structure
-- `src/preload`: sichere IPC Bridge
-- `src/renderer`: React UI
-- `src/shared`: gemeinsame Typen und IPC-Channel
-- `tests`: Unit- und Self-Check Tests
 
-## Hinweise
+- `src/main` - Electron main process, queue/download/provider logic
+- `src/preload` - secure IPC bridge between main and renderer
+- `src/renderer` - React UI
+- `src/shared` - shared types and IPC contracts
+- `tests` - unit tests and self-check tests
+- `resources/extractor-jvm` - SevenZipJBinding + Zip4j sidecar JAR and native libraries
 
-- Runtime-Dateien liegen im Electron `userData` Verzeichnis:
+## Data and logs
-  - `rd_downloader_config.json`
-  - `rd_session_state.json`
-  - `rd_downloader.log`
 
-- Das Repository enthält jetzt nur noch die aktive Node/Electron-Codebasis.
+The app stores runtime files in Electron's `userData` directory, including:
+
+- `rd_downloader_config.json`
+- `rd_session_state.json`
+- `rd_downloader.log`
+
+## Troubleshooting
+
+- Download does not start: verify token and selected provider in Settings.
+- Extraction fails: check archive passwords and native extractor installation (7-Zip/WinRAR). Optional JVM extractor can be forced with `RD_EXTRACT_BACKEND=jvm`.
+- Very slow downloads: check active speed limit and bandwidth schedules.
+- Unexpected interruptions: enable reconnect and fallback providers.
+- Stalled downloads: the app auto-detects stalls within 10 seconds and retries automatically.
+
+## Changelog
+
+Release history is available on [git.24-music.de Releases](https://git.24-music.de/Administrator/real-debrid-downloader/releases).
+
+### v1.6.61 (2026-03-05)
+
+- Fixed leftover empty package folders in `Downloader Unfertig` after successful extraction.
+- Resume marker files (`.rd_extract_progress*.json`) are now treated as ignorable for empty-folder cleanup.
+- Deferred post-processing now clears resume markers before running empty-directory removal.
+
+### v1.6.60 (2026-03-05)
+
+- Added package-scoped password cache for extraction: once the first archive in a package is solved, following archives in the same package reuse that password first.
+- Kept fallback behavior intact (`""` and other candidates are still tested), but moved empty-password probing behind the learned password to reduce per-archive delays.
+- Added cache invalidation on real `wrong_password` failures so stale passwords are automatically discarded.
+
+### v1.6.59 (2026-03-05)
+
+- Switched default extraction backend to native tools (`legacy`) for more stable archive-to-archive flow.
+- Prioritized 7-Zip as primary native extractor, with WinRAR/UnRAR as fallback.
+- JVM extractor remains available as opt-in via `RD_EXTRACT_BACKEND=jvm`.
+
+### v1.6.58 (2026-03-05)
+
+- Fixed extraction progress oscillation (`1% -> 100% -> 1%` loops) during password retries.
+- Kept strict archive completion logic, but normalized in-progress archive percent to avoid false visual done states before real completion.
+
+### v1.6.57 (2026-03-05)
+
+- Fixed extraction flow so archives are marked done only on real completion, not on temporary `100%` progress spikes.
+- Improved password handling: after the first successful archive, the discovered password is prioritized for subsequent archives.
+- Fixed progress parsing for password retries (reset/restart handling), reducing visible and real gaps between archive extractions.

+# JVM extractor runtime
+
+This directory contains the Java sidecar runtime used by `src/main/extractor.ts`.
+
+## Included backends
+
+- `sevenzipjbinding` for the primary extraction path (RAR/7z/ZIP and others)
+- `zip4j` for ZIP multipart handling (JD-style split ZIP behavior)
+
+## Layout
+
+- `classes/` compiled `JBindExtractorMain` classes
+- `lib/` runtime jars required by the sidecar
+- `src/` Java source for the sidecar
+
+## Rebuild notes
+
+The checked-in classes are Java 8 compatible and built from:
+
+`resources/extractor-jvm/src/com/sucukdeluxe/extractor/JBindExtractorMain.java`
+
+If you need to rebuild, compile against the jars in `lib/` with a Java 8-compatible compiler.
