refactor: Change logging level from info to debug for download and JS messages

- Introduced multiple JavaScript scripts for handling drag & drop functionality:
  - `bridge_script.js`: Original implementation with popup prevention.
  - `bridge_script_debug.js`: Debug version with extensive logging for troubleshooting.
  - `bridge_script_v2.js`: Enhanced version extending DataTransfer for better integration.
  - `bridge_script_hybrid.js`: Hybrid approach allowing parallel native file drag.
  - `bridge_script_drop_intercept.js`: Intercepts drop events for custom handling.
  - `bridge_script_intercept.js`: Prevents browser drag for ALT+drag, using Qt for file drag.

- Added detailed documentation in `SCRIPT_VARIANTS.md` outlining usage, status, and recommended workflows for each script.
- Implemented logging features to capture drag events, DataTransfer modifications, and network requests for better debugging.
- Enhanced DataTransfer handling to support Windows-specific file formats and improve user experience during drag & drop operations.

 ## Code Standards
 
 ### Python Style
-- **Formatter**: Black (100 character line length)
-- **Linter**: Ruff
-- **Type Hints**: Required for all public APIs
-- **Docstrings**: Google-style format
+- **Formatter**: Black (88 character line length)
+- **Import Sorter**: isort (black-compatible profile)
+- **Linter**: Ruff (checks style, security, complexity)
+- **Type Checker**: mypy (strict mode for core modules)
+- **Type Hints**: Required for all public APIs and core modules
+- **Docstrings**: Google-style format (module, class, function level)
 
 ### Example
 ```python
+"""Module for path validation."""

 ## Before Making Changes
 
-1. **Check the development plan**: See `DEVELOPMENT_PLAN.md` for current phase and priorities
-2. **Understand the architecture**: Read `docs/ARCHITECTURE.md`
-3. **Follow the structure**: Keep code organized in appropriate modules (core/, ui/, utils/)
-4. **Write tests first**: Use TDD approach - write tests before implementing
+1. **Check the development plan**: See [DEVELOPMENT_PLAN.md](../../DEVELOPMENT_PLAN.md) - currently Phase 4 Complete, Phase 5 in planning
+2. **Understand the architecture**: Read [docs/ARCHITECTURE.md](../../docs/ARCHITECTURE.md)
+3. **Review actual implementation**: Look at existing modules in core/, ui/, utils/
+4. **Follow the structure**: Keep code organized in appropriate modules
+5. **Write tests**: Use pytest - write tests for new functionality
 
 ## Making Changes
 
-1. **Run existing tests first**: `pytest tests -v`
-2. **Create test file**: `tests/unit/test_*.py`
-3. **Write failing test**: Verify it fails before implementing
-4. **Implement feature**: Follow code standards above
-5. **Run tests**: `pytest tests -v --cov`
-6. **Run quality checks**: `tox -e lint,type`
-7. **Update docs**: Add docstrings and update README if needed
+1. **Run existing tests first**: `pytest tests -v` (should pass)
+2. **Create test file**: `tests/unit/test_*.py` or `tests/integration/test_*.py`
+3. **Write test**: Verify test executes (may fail if feature incomplete)
+4. **Implement feature**: Follow code standards (black, ruff, isort, mypy)
+5. **Format code**: `tox -e format` (auto-formats with black/isort)
+6. **Run all checks**: `tox -e lint,type` (ruff, mypy validation)
+7. **Run tests with coverage**: `pytest tests --cov=src/webdrop_bridge`
+8. **Update docs**: Add/update docstrings, README if needed
 
 ## Development Environment
 
 **Virtual Environment**: `.venv` (already created)

 ## What NOT to Do
 
-❌ Change architecture without discussion
-❌ Add dependencies without updating pyproject.toml
-❌ Merge without tests passing
-❌ Remove type hints or docstrings
-❌ Commit without running `tox -e lint,type`
-❌ Add platform-specific code without tests
+❌ Change architecture without reviewing DEVELOPMENT_PLAN.md first
+❌ Add dependencies without updating requirements-dev.txt and pyproject.toml
+❌ Commit without running `tox -e format,lint,type`
+❌ Remove type hints or docstrings from public APIs
+❌ Add imports without running `tox -e format` (isort cleanup)
+❌ Add platform-specific code without tests marked with @pytest.mark.windows or @pytest.mark.macos
+❌ Modify path validation logic without security review
+❌ Force-push to main or release branches
 
 ## Notes for Modifications
 
 - This is a production-quality application, not a PoC
-- Code quality and testing are non-negotiable
-- Cross-platform support (Windows + macOS) is required
-- User security (path validation) is critical
-- Documentation must keep pace with code
+- Code quality, testing, and documentation are non-negotiable

-# Configuration System Overhaul - Summary
-
-## Problem Identified
-
-The application was **not bundling the `.env` configuration file** into built executables. This meant:
-
-❌ End users received applications with **no configuration**
-❌ Hardcoded defaults in `config.py` were used instead
-❌ No way to support different customers with different configurations
-❌ Users had to manually create `.env` files after installation
-
-## Solution Implemented
-
-Enhanced the build system to **bundle `.env` files into executables** with support for customer-specific configurations.
-
-### Key Changes
-
-#### 1. **Windows Build Script** (`build/scripts/build_windows.py`)
-- Added `--env-file` command-line parameter
-- Validates `.env` file exists before building
-- Passes `.env` path to PyInstaller via environment variable
-- Provides helpful error messages if `.env` is missing
-- Full argument parsing with `argparse`
-
-**Usage:**
-```bash
-# Default: uses .env from project root
-python build_windows.py --msi
-
-# Custom config for a customer
-python build_windows.py --msi --env-file customer_configs/acme.env
-```
-
-#### 2. **macOS Build Script** (`build/scripts/build_macos.sh`)
-- Added `--env-file` parameter (shell-based)
-- Validates `.env` file exists before building
-- Exports environment variable for spec file
-- Same functionality as Windows version
-
-**Usage:**
-```bash
-# Default: uses .env from project root
-bash build_macos.sh
-
-# Custom config
-bash build_macos.sh --env-file customer_configs/acme.env
-```
-
-#### 3. **PyInstaller Spec File** (`build/webdrop_bridge.spec`)
-- Now reads environment variable `WEBDROP_ENV_FILE`
-- Defaults to project root `.env` if not specified
-- **Validates .env exists** before bundling
-- Includes `.env` in PyInstaller's `datas` section
-- File is placed in application root, ready for `Config.from_env()` to find
-
-**Changes:**
-```python
-# Get env file from environment variable (set by build script)
-# Default to .env in project root if not specified
-env_file = os.getenv("WEBDROP_ENV_FILE", os.path.join(project_root, ".env"))
-
-# Verify env file exists
-if not os.path.exists(env_file):
-    raise FileNotFoundError(f"Configuration file not found: {env_file}")
-
-# Include in datas
-datas=[
-    ...
-    (env_file, "."),  # Include .env file in the root of bundled app
-]
-```
-
-#### 4. **Documentation** (`docs/CONFIGURATION_BUILD.md`)
-- Complete guide on configuration management
-- Examples for default and custom configurations
-- Multi-customer setup examples
-- Build command reference for Windows and macOS
-
-## How It Works
-
-### At Build Time
-1. User specifies `.env` file (or uses default from project root)
-2. Build script validates the file exists
-3. PyInstaller bundles the `.env` into the application
-4. Users receive a pre-configured executable
-
-### At Runtime
-1. Application starts and calls `Config.from_env()`
-2. Looks for `.env` in the current working directory
-3. Finds the bundled `.env` file
-4. Loads all configuration (URLs, paths, logging, etc.)
-5. Application starts with customer-specific settings
-
-## Benefits
-
-✅ **Multi-customer support** - Build different configs for different clients
-✅ **No user setup** - Configuration is included in the installer
-✅ **Safe builds** - Process fails if `.env` doesn't exist
-✅ **Override capability** - Users can edit `.env` after installation if needed
-✅ **Clean deployment** - Each customer gets exactly what they need
-
-## Example: Multi-Customer Deployment
-
-```
-customer_configs/
-├── acme_corp.env
-│   WEBAPP_URL=https://acme.example.com
-│   ALLOWED_ROOTS=Z:/acme_files/
-├── globex.env
-│   WEBAPP_URL=https://globex.example.com
-│   ALLOWED_ROOTS=C:/globex_data/
-└── initech.env
-    WEBAPP_URL=https://initech.example.com
-    ALLOWED_ROOTS=D:/initech/
-```
-
-Build for each:
-```bash
-python build_windows.py --msi --env-file customer_configs/acme_corp.env
-python build_windows.py --msi --env-file customer_configs/globex.env
-python build_windows.py --msi --env-file customer_configs/initech.env
-```
-
-Each MSI includes the customer's specific configuration.
-
-## Files Modified
-
-1. ✅ `build/scripts/build_windows.py` - Enhanced with `.env` support
-2. ✅ `build/scripts/build_macos.sh` - Enhanced with `.env` support
-3. ✅ `build/webdrop_bridge.spec` - Now includes `.env` in bundle
-4. ✅ `docs/CONFIGURATION_BUILD.md` - New comprehensive guide
-
-## Build Command Quick Reference
-
-### Windows
-```bash
-# Default configuration
-python build/scripts/build_windows.py --msi
-
-# Custom configuration
-python build/scripts/build_windows.py --msi --env-file path/to/config.env
-
-# Without MSI (just EXE)
-python build/scripts/build_windows.py
-
-# With code signing
-python build/scripts/build_windows.py --msi --code-sign
-```
-
-### macOS
-```bash
-# Default configuration
-bash build/scripts/build_macos.sh
-
-# Custom configuration
-bash build/scripts/build_macos.sh --env-file path/to/config.env
-
-# With signing
-bash build/scripts/build_macos.sh --sign
-
-# With notarization
-bash build/scripts/build_macos.sh --notarize
-```
-
-## Testing
-
-To test the new functionality:
-
-```bash
-# 1. Verify default build (uses project .env)
-python build/scripts/build_windows.py --help
-
-# 2. Create a test .env with custom values
-# (or use existing .env)
-
-# 3. Try building (will include .env)
-# python build/scripts/build_windows.py --msi
-```
-
-## Next Steps
-
-- ✅ Configuration bundling implemented
-- ✅ Multi-customer support enabled
-- ✅ Documentation created
-- 🔄 Test builds with different `.env` files (optional)
-- 🔄 Document in DEVELOPMENT_PLAN.md if needed
-
-## Backward Compatibility
-
-✅ **Fully backward compatible**
-- Old code continues to work
-- Default behavior (use project `.env`) is the same
-- No changes required for existing workflows
-- New `--env-file` parameter is optional

+# WebDrop Bridge Configuration Guide
+
+## Configuration File Location
+
+WebDrop Bridge supports two configuration methods:
+
+1. **JSON Configuration File** (Recommended for Azure URL mapping)
+   - Windows: `%APPDATA%\webdrop_bridge\config.json`
+   - macOS/Linux: `~/.config/webdrop_bridge/config.json`
+
+2. **Environment Variables** (`.env` file in project root)
+   - Used as fallback if JSON config doesn't exist
+
+## JSON Configuration Format
+
+Create a `config.json` file with the following structure:
+
+```json
+{
+  "app_name": "WebDrop Bridge",
+  "webapp_url": "https://wps.agravity.io/",
+  "url_mappings": [
+    {
+      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
+      "local_path": "Z:"
+    }
+  ],
+  "allowed_roots": [
+    "Z:\\"
+  ],
+  "allowed_urls": [],
+  "check_file_exists": true,
+  "auto_check_updates": true,
+  "update_check_interval_hours": 24,
+  "log_level": "INFO",
+  "log_file": "logs/webdrop_bridge.log",
+  "window_width": 1024,
+  "window_height": 768,
+  "enable_logging": true
+}
+```
+
+## Configuration Options
+
+### Core Settings
+
+- **`webapp_url`** (string): URL of the web application to load
+  - Example: `"https://wps.agravity.io/"`
+  - Supports `http://`, `https://`, or `file:///` URLs
+
+- **`url_mappings`** (array): Azure Blob Storage URL to local path mappings
+  - Each mapping has:
+    - `url_prefix`: Azure URL prefix (must end with `/`)
+    - `local_path`: Local drive letter or path
+  - Example:
+    ```json
+    {
+      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
+      "local_path": "Z:"
+    }
+    ```
+
+- **`allowed_roots`** (array): Whitelisted root directories for file access
+  - Security feature: Only files within these directories can be dragged
+  - Example: `["Z:\\", "C:\\Users\\Public"]`
+
+### Azure URL Mapping Example
+
+When the web application provides a drag URL like:
+```
+https://wpsagravitystg.file.core.windows.net/wpsagravitysync/aN5PysnXIuRECzcRbvHkjL7g0/Hintergrund_Agravity.png
+```
+

+```
+
+### Security Settings
+
+- **`check_file_exists`** (boolean): Validate files exist before allowing drag
+  - Default: `true`
+  - Set to `false` only for testing
+
+- **`allowed_urls`** (array): Allowed URL patterns for web content
+  - Empty array = no restriction
+  - Example: `["wps.agravity.io", "*.example.com"]`
+
+### Update Settings
+
+- **`auto_check_updates`** (boolean): Automatically check for updates on startup
+  - Default: `true`
+
+- **`update_check_interval_hours`** (number): Hours between update checks
+  - Default: `24`
+
+### UI Settings
+
+- **`window_width`**, **`window_height`** (number): Initial window size in pixels
+  - Default: `1024` x `768`
+
+- **`log_level`** (string): Logging verbosity
+  - Options: `"DEBUG"`, `"INFO"`, `"WARNING"`, `"ERROR"`, `"CRITICAL"`
+  - Default: `"INFO"`
+
+- **`enable_logging`** (boolean): Whether to write logs to file
+  - Default: `true`
+
+## Quick Start
+
+1. Copy `config.example.json` to your config directory:
+   ```powershell
+   # Windows
+   mkdir "$env:APPDATA\webdrop_bridge"
+   copy config.example.json "$env:APPDATA\webdrop_bridge\config.json"
+   ```
+
+2. Edit the configuration file with your Azure URL mappings and local paths
+
+3. Restart WebDrop Bridge
+
+## Multiple URL Mappings
+
+You can configure multiple Azure storage accounts:
+
+```json
+{
+  "url_mappings": [
+    {
+      "url_prefix": "https://storage1.file.core.windows.net/container1/",
+      "local_path": "Z:"
+    },
+    {
+      "url_prefix": "https://storage2.file.core.windows.net/container2/",
+      "local_path": "Y:"
+    }
+  ],
+  "allowed_roots": [
+    "Z:\\",
+    "Y:\\"
+  ]
+}
+```
+
+## Environment Variable Fallback
+
+If no JSON config exists, WebDrop Bridge will load from `.env`:
+
+```env
+APP_NAME=WebDrop Bridge
+WEBAPP_URL=https://wps.agravity.io/
+ALLOWED_ROOTS=Z:/
+LOG_LEVEL=INFO
+WINDOW_WIDTH=1024
+WINDOW_HEIGHT=768
+```
+
+**Note:** Environment variables don't support `url_mappings`. Use JSON config for Azure URL mapping.
+
+## Troubleshooting
+
+### "No mapping found for URL"
+- Check that `url_prefix` matches the Azure URL exactly (including trailing `/`)
+- Verify `url_mappings` is configured in your JSON config file
+- Check logs in `logs/webdrop_bridge.log`
+
+### "Path is not within allowed roots"
+- Ensure the mapped local path (e.g., `Z:`) is listed in `allowed_roots`
+- Make sure the drive is mounted and accessible
+
+### "File does not exist"
+- Verify the Azure sync is working and files are available locally
+- Set `check_file_exists: false` temporarily for testing
+- Check that the path mapping is correct
+
+## Example Configurations
+
+### Production (Agravity WPS)
+
+```json
+{
+  "webapp_url": "https://wps.agravity.io/",
+  "url_mappings": [
+    {
+      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
+      "local_path": "Z:"
+    }
+  ],
+  "allowed_roots": ["Z:\\"],
+  "log_level": "INFO"
+}
+```
+
+### Development (Local Testing)
+
+```json
+{
+  "webapp_url": "file:///./webapp/index.html",
+  "url_mappings": [
+    {
+      "url_prefix": "https://test.blob.core.windows.net/test/",
+      "local_path": "C:\\temp\\test"
+    }
+  ],
+  "allowed_roots": ["C:\\temp\\test"],
+  "check_file_exists": false,
+  "log_level": "DEBUG"
+}

-# Forgejo Releases Distribution Guide
-
-This guide explains how to distribute WebDrop Bridge builds using **Forgejo Releases** with binary assets.
-
-## Overview
-
-**Forgejo Releases** is the standard way to distribute binaries. Attach exe/dmg and checksum files to releases.
-
-```
-1. Build locally (Windows & macOS)
-2. Create Release (v1.0.0)
-3. Upload exe + dmg as release assets
-4. UpdateManager downloads from release
-5. Users verify with SHA256 checksums
-```
-
-## Setup Requirements
-
-### 1. Use Your Existing Forgejo Credentials
-
-You already have HTTP access to Forgejo. Just use the same username and password you use to log in.
-
-Set environment variables with your Forgejo credentials:
-
-**Windows (PowerShell):**
-```powershell
-$env:FORGEJO_USER = "your_forgejo_username"
-$env:FORGEJO_PASS = "your_forgejo_password"
-```
-
-**macOS/Linux:**
-```bash
-export FORGEJO_USER="your_forgejo_username"
-export FORGEJO_PASS="your_forgejo_password"
-```
-
-### 2. Build Scripts
-
-Upload scripts are already created:
-- Windows: `build/scripts/upload_to_packages.ps1`
-- macOS: `build/scripts/upload_to_packages.sh`
-
-## Release Workflow
-
-### Step 1: Build Executables
-
-**On Windows:**
-```powershell
-cd C:\Development\VS Code Projects\webdrop_bridge
-python build/scripts/build_windows.py
-# Output: build/dist/windows/WebDropBridge.exe
-#         build/dist/windows/WebDropBridge.exe.sha256
-```
-
-**On macOS:**
-```bash
-cd ~/webdrop_bridge
-bash build/scripts/build_macos.sh
-# Output: build/dist/macos/WebDropBridge.dmg
-#         build/dist/macos/WebDropBridge.dmg.sha256
-```
-
-### Step 2: Upload to Release
-
-After setting your environment variables (see Setup Requirements above), creating a release is simple:
-
-**Windows Upload:**
-```powershell
-$env:FORGEJO_USER = "your_username"
-$env:FORGEJO_PASS = "your_password"
-.\build\scripts\create_release.ps1 -Version 1.0.0
-```
-
-**macOS Upload:**
-```bash
-export FORGEJO_USER="your_username"
-export FORGEJO_PASS="your_password"
-bash build/scripts/create_release.sh -v 1.0.0
-```
-
-Or set the environment variables once and they persist for all future releases in that terminal session.
-
-The script will:
-1. Create a release with tag `v1.0.0`
-2. Upload the executable as an asset
-3. Upload the checksum as an asset
-
-### Step 3: Commit the Tag
-
-The release script creates the git tag automatically. Push it:
-
-```bash
-git push upstream v1.0.0
-```
-
-## Forgejo Releases API
-
-### Get Latest Release
-
-```bash
-curl https://git.him-tools.de/api/v1/repos/HIM-public/webdrop-bridge/releases/latest
-```
-
-Response includes assets array with download URLs for exe, dmg, and checksums.
-
-### Download URLs
-
-After creating a release, assets are available at:
-```
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe.sha256
-```
-
-### Direct Release Page
-
-```
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases
-```
-
-## UpdateManager Integration (Phase 4.1)
-
-The auto-update system will query the Releases API:
-
-```python
-async def check_for_updates(self) -> Optional[UpdateInfo]:
-    """Query Forgejo Releases for new version."""

-
-## Troubleshooting
-
-### Release creation fails with "409 Conflict"
-
-- Tag already exists
-- Use a different version number
-
-### Release creation fails with "401 Unauthorized"
-
-- Verify credentials are correct
-- Check you have write access to repo
-
-### Asset upload fails
-
-- Check file exists and is readable
-- Verify file isn't too large (Forgejo may have limits)
-- Try again, transient network issues can occur
-
-### Where are my releases?
-
-View all releases at:
-```
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases
-```
-
-Each release shows:
-- Version/tag name
-- Release date
-- Release notes
-- Attached assets with download links
-
-## Manual Download
-
-Users can download directly from releases:
-```
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.dmg
-```
-
-Or via Releases page UI:
-```
-https://git.him-tools.de/HIM-public/webdrop-bridge/releases

-✅ **Simple**: No special setup needed  
-✅ **Flexible**: Build when you want  
-✅ **Standard**: Same as most open-source projects  
-✅ **Auto-Update Ready**: UpdateManager queries easily  
-✅ **User Friendly**: Download from releases page  
-
-
-## Release Script Details
-
-### Windows Script (`create_release.ps1`)
-
-**Basic Usage:**
-```powershell
-# Set your Forgejo credentials
-$env:FORGEJO_USER = "your_username"
-$env:FORGEJO_PASS = "your_password"
-
-# Create release
-.\build\scripts\create_release.ps1 -Version 1.0.0
-```
-
-**Parameters:**
-- `-Version` - Version number (required, e.g., "1.0.0")
-- `-ForgejoUser` - Forgejo username (optional if `$env:FORGEJO_USER` set)
-- `-ForgejoPW` - Forgejo password (optional if `$env:FORGEJO_PASS` set)
-- `-ForgejoUrl` - Forgejo server URL (default: https://git.him-tools.de)
-- `-Repo` - Repository (default: HIM-public/webdrop-bridge)
-- `-ExePath` - Path to exe file (default: build\dist\windows\WebDropBridge.exe)
-- `-ChecksumPath` - Path to checksum file
-- `-ClearCredentials` - Clear saved credentials from this session
-
-**Script flow:**
-1. Check for credentials in: parameter → environment variables → prompt user
-2. Save credentials to environment for future use
-3. Create release with tag `v{Version}`
-4. Upload exe as asset
-5. Upload checksum as asset
-6. Show success message with release URL
-
-### macOS Script (`create_release.sh`)
-
-**Basic Usage:**
-```bash
-# Set your Forgejo credentials
-export FORGEJO_USER="your_username"
-export FORGEJO_PASS="your_password"
-
-# Create release
-bash build/scripts/create_release.sh -v 1.0.0
-```
-
-**Options:**
-- `-v, --version` - Version number (required, e.g., "1.0.0")
-- `-u, --url` - Forgejo server URL (default: https://git.him-tools.de)
-- `--clear-credentials` - Clear saved credentials from this session
-
-**Script flow:**
-1. Check for credentials in: environment variables → prompt user
-2. Export credentials for future use
-3. Create release with tag `v{Version}`
-4. Upload dmg as asset
-5. Upload checksum as asset
-6. Show success message with release URL
-
-### Credential Resolution
-
-Both scripts use HTTP Basic Authentication with your Forgejo username/password:
-- Same credentials you use to log into Forgejo
-- Same credentials git uses when cloning over HTTPS
-- No special token creation needed
-- First run prompts for credentials, saves to session
-

-   
-   manager = UpdateManager(
-       repo_url="https://git.him-tools.de/HIM-public/webdrop-bridge",
-       current_version="0.0.2"
-   )
-   
-   if manager.update_available():
-       manager.download_and_install()
-       manager.restart_app()
-   ```
-
-3. **Forgejo API Endpoint**
-   ```

-   # Install WiX Toolset first
-   python build/scripts/build_windows.py --msi
-   # Output: WebDropBridge-Setup.exe
-   ```
-
-### Deferred Tasks
-
-4. **GitHub Actions CI/CD Pipeline** (`.github/workflows/build.yml`)
-   - Automated Windows builds on release tag
-   - macOS builds on release tag
-   - Checksum generation
-   - Upload to releases
-
-5. **Code Signing & Notarization**
-   - Windows: Requires code signing certificate
-   - macOS: Requires Apple Developer ID and notarization credentials
-
----
-
-## Configuration Files Added
-
-### For Windows Builds
-```python
-# build/scripts/build_windows.py
-class WindowsBuilder:
-    def __init__(self, project_root: Path):
-        self.project_root = project_root
-        self.build_dir = project_root / "build"
-        ...
-```
-
-### For macOS Builds
-```bash
-# build/scripts/build_macos.sh
-PROJECT_ROOT="$(dirname "$(dirname "$( cd "$(dirname "${BASH_SOURCE[0]}")" && pwd )")")"
-APP_NAME="WebDropBridge"
-DMG_NAME="WebDropBridge.dmg"
-```
-
-### PyInstaller Configuration
-```python
-# build/webdrop_bridge.spec
-SPECPATH = os.path.dirname(os.path.abspath(spec_file))
-project_root = os.path.dirname(SPECPATH)
-
-a = Analysis(
-    [os.path.join(project_root, 'src/webdrop_bridge/main.py')],
-    ...
-    datas=[
-        (os.path.join(project_root, 'webapp'), 'webapp'),
-        (os.path.join(project_root, 'resources'), 'resources'),
-    ],
-)
-```
-
----
-
-## Technical Decisions & Rationale
-
-### 1. PyInstaller Spec File (Not CLI Arguments)
-- **Decision**: Use .spec file instead of CLI args
-- **Rationale**: Better cross-platform compatibility, easier to maintain, supports complex bundling
-- **Result**: Unified spec works for both Windows and macOS
-
-### 2. Separate Build Scripts (Windows Python, macOS Bash)
-- **Decision**: Python for Windows, Bash for macOS
-- **Rationale**: Windows Python is most portable, macOS scripts integrate better with shell tools
-- **Result**: Platform-native experience, easier CI/CD integration
-
-### 3. Large Executable Size (195.66 MB)
-- **Expected**: Yes, includes:
-  - Python runtime (~50 MB)
-  - PySide6/Qt6 libraries (~80 MB)
-  - Embedded Chromium browser (~50 MB)
-  - Application code and resources (~15 MB)
-- **Mitigation**: Users get single-file download, no external dependencies
-
-### 4. Cross-Platform Data File Bundling
-- **Decision**: Include webapp/ and resources/ in executables
-- **Rationale**: Self-contained distribution, no external file dependencies
-- **Result**: Users can place executable anywhere, always works

-# Update Feature Fixes - Final Summary
-
-## Problem Identified
-The update feature was causing the application to hang indefinitely when clicked. The issue had two components:
-
-1. **UI Thread Blocking**: The original code was running download operations synchronously on the UI thread
-2. **Network Timeout Issues**: Even with timeouts set, the socket-level network calls would hang indefinitely if the server didn't respond
-
-## Solutions Implemented
-
-### 1. Background Threading (First Fix)
-- Created `UpdateDownloadWorker` class to run download operations in a background thread
-- Moved blocking network calls off the UI thread
-- This prevents the UI from freezing while waiting for network operations
-
-### 2. Aggressive Timeout Strategy (Second Fix)
-Applied timeouts at multiple levels to ensure the app never hangs:
-
-#### A. Socket-Level Timeout (Most Important)
-- **File**: `src/webdrop_bridge/core/updater.py`
-- Reduced `urlopen()` timeout from 10 seconds to **5 seconds**
-- This is the first line of defense against hanging socket connections
-- Applied in `_fetch_release()` method
-
-#### B. Asyncio-Level Timeout
-- **File**: `src/webdrop_bridge/ui/main_window.py` and `src/webdrop_bridge/core/updater.py`
-- `UpdateCheckWorker`: 10-second timeout on entire check operation
-- `UpdateDownloadWorker`: 300-second timeout on download, 30-second on verification
-- `check_for_updates()`: 8-second timeout on async executor
-- These catch any remaining hangs in the asyncio operations
-
-#### C. Qt-Level Timeout (Final Safety Net)
-- **File**: `src/webdrop_bridge/ui/main_window.py`
-- Update check: **30-second QTimer** safety timeout (`_run_async_check()`)
-- Download: **10-minute QTimer** safety timeout (`_perform_update_async()`)
-- If nothing else works, Qt's event loop will forcefully close the operation
-
-### 3. Error Handling Improvements
-- Added proper exception handling for `asyncio.TimeoutError`
-- Better logging to identify where hangs occur
-- User-friendly error messages like "no server response" or "Operation timed out"
-- Graceful degradation: operations fail fast instead of hanging
-

-```
-
-## Files Modified
-1. **src/webdrop_bridge/ui/main_window.py**
-   - Updated `UpdateCheckWorker.run()` with timeout handling
-   - Updated `UpdateDownloadWorker.run()` with timeout handling
-   - Added QTimer safety timeouts in `_run_async_check()` and `_perform_update_async()`
-   - Proper event loop cleanup in finally blocks
-
-2. **src/webdrop_bridge/core/updater.py**
-   - Reduced socket timeout in `_fetch_release()` from 10s to 5s
-   - Added timeout to `check_for_updates()` async operation
-   - Added timeout to `download_update()` async operation
-   - Added timeout to `verify_checksum()` async operation
-   - Better error logging with exception types
-
-## Testing
-- All 7 integration tests pass
-- Timeout verification script confirms all timeout mechanisms are in place
-- No syntax errors in modified code
-
-## Result
-The application will no longer hang indefinitely when checking for or downloading updates. Instead:
-- Operations timeout quickly (5-30 seconds depending on operation type)
-- User gets clear feedback about what went wrong
-- User can retry or cancel without force-killing the app
-- Background threads are properly cleaned up to avoid resource leaks

VERSIONING_SIMPLIFIED.md

-# Simplified Versioning System
-
-## Problem Solved
-
-Previously, the application version had to be manually updated in **multiple places**:
-1. `src/webdrop_bridge/__init__.py` - source of truth
-2. `pyproject.toml` - package version
-3. `.env.example` - environment example
-4. Run `scripts/sync_version.py` - manual sync step
-
-This was error-prone and tedious.
-
-## Solution: Single Source of Truth
-
-The version is now defined **only in one place**:
-
-```python
-# src/webdrop_bridge/__init__.py
-__version__ = "1.0.0"
-```
-
-All other components automatically read from this single source.
-
-## How It Works
-
-### 1. **pyproject.toml** (Automatic)
-```toml
-[tool.setuptools.dynamic]
-version = {attr = "webdrop_bridge.__version__"}
-
-[project]
-name = "webdrop-bridge"
-dynamic = ["version"]  # Reads from __init__.py
-```
-
-When you build the package, setuptools automatically extracts the version from `__init__.py`.
-
-### 2. **config.py** (Automatic - with ENV override)
-```python
-# Lazy import to avoid circular imports
-if not os.getenv("APP_VERSION"):
-    from webdrop_bridge import __version__
-    app_version = __version__
-else:
-    app_version = os.getenv("APP_VERSION")
-```
-
-The config automatically reads from `__init__.py`, but can be overridden with the `APP_VERSION` environment variable if needed.
-
-### 3. **sync_version.py** (Simplified)
-The script now only handles:
-- Updating `__init__.py` with a new version
-- Updating `CHANGELOG.md` with a new version header
-- Optional: updating `.env.example` if it explicitly sets `APP_VERSION`
-
-It **no longer** needs to manually sync pyproject.toml or config defaults.
-
-## Workflow
-
-### To Release a New Version
-
-**Option 1: Simple (Recommended)**
-```bash
-# Edit only one file
-# src/webdrop_bridge/__init__.py:
-__version__ = "1.1.0"  # Change this
-
-# Then run sync script to update changelog
-python scripts/sync_version.py
-```
-
-**Option 2: Using the Sync Script**
-```bash
-python scripts/sync_version.py --version 1.1.0
-```
-
-The script will:
-- ✅ Update `__init__.py`
-- ✅ Update `CHANGELOG.md`
-- ✅ (Optional) Update `.env.example` if it has `APP_VERSION=`
-
-### What Happens Automatically
-
-When you run your application:
-1. Config loads and checks environment for `APP_VERSION`
-2. If not set, it imports `__version__` from `__init__.py`
-3. The version is displayed in the UI
-4. Update checks use the correct version
-
-When you build with `pip install`:
-1. setuptools reads `__version__` from `__init__.py`
-2. Package metadata is set automatically
-3. No manual sync needed
-
-## Verification
-
-To verify the version is correctly propagated:
-
-```bash
-# Check __init__.py
-python -c "from webdrop_bridge import __version__; print(__version__)"
-
-# Check config loading
-python -c "from webdrop_bridge.config import Config; c = Config.from_env(); print(c.app_version)"
-
-# Check package metadata (after building)
-pip show webdrop-bridge
-```
-
-All should show the same version.
-
-## Best Practices
-
-1. **Always edit `__init__.py` first** - it's the single source of truth
-2. **Run `sync_version.py` to update changelog** - keeps release notes organized
-3. **Use environment variables only for testing** - don't hardcode overrides
-4. **Run tests after version changes** - config tests verify version loading
-
-## Migration Notes
-
-If you had other places where version was defined:
-- ❌ Remove version from `pyproject.toml` `[project]` section  
-- ✅ Add `dynamic = ["version"]` instead
-- ❌ Don't manually edit `.env.example` for version  
-- ✅ Let `sync_version.py` handle it
-- ❌ Don't hardcode version in config.py defaults
-- ✅ Use lazy import from `__init__.py`
-
-## Testing the System
-
-Run the config tests to verify everything works:
-```bash
-pytest tests/unit/test_config.py -v
-```
-
-All tests should pass, confirming version loading works correctly.
-
----
-
-**Result**: One place to change, multiple places automatically updated. Simple, clean, professional.

-# WebApp Loading - Issue & Fix Summary
-
-## Problem
-
-When running the Windows executable, the embedded web view displayed:
-
-```
-Error
-Web application file not found: C:\Development\VS Code Projects\webdrop_bridge\file:\webapp\index.html
-```
-
-### Root Causes
-
-1. **Path Resolution Issue**: When the app runs from a bundled executable (PyInstaller), the default webapp path `file:///./webapp/index.html` is resolved relative to the current working directory, not relative to the executable location.
-
-2. **No Fallback UI**: When the webapp file wasn't found, users saw a bare error page instead of a helpful welcome/status page.
-
-## Solution
-
-### 1. Improved Path Resolution (main_window.py)
-
-Enhanced `_load_webapp()` method to:
-- First try the configured path as-is
-- If not found, try relative to the application package root
-- Handle both development mode and PyInstaller bundled mode
-- Work with `file://` URLs and relative paths
-
-```python
-def _load_webapp(self) -> None:
-    if not file_path.exists():
-        # Try relative to application package root
-        # This handles both development and bundled (PyInstaller) modes
-        app_root = Path(__file__).parent.parent.parent.parent
-        relative_path = app_root / webapp_url.lstrip("file:///").lstrip("./")
-        
-        if relative_path.exists():
-            file_path = relative_path
-```
-
-### 2. Beautiful Default Welcome Page
-
-Created `DEFAULT_WELCOME_PAGE` constant with professional UI including:
-- **Status message**: Shows when no web app is configured
-- **Application info**: Name, version, description
-- **Key features**: Drag-drop, validation, cross-platform support
-- **Configuration guide**: Instructions to set up custom webapp
-- **Professional styling**: Gradient background, clean layout, accessibility
-
-### 3. Updated Error Handling
-
-When webapp file is not found, the app now:
-- Shows the welcome page instead of a bare error message
-- Provides clear instructions on how to configure a web app
-- Displays the version number
-- Gives users a professional first impression
-
-## Files Modified
-
-### `src/webdrop_bridge/ui/main_window.py`
-- Added `DEFAULT_WELCOME_PAGE` HTML constant with professional styling
-- Enhanced `_load_webapp()` method with multi-path resolution
-- Added welcome page as fallback for missing/error conditions
-
-### `tests/unit/test_main_window.py`
-- Renamed test: `test_load_nonexistent_file_shows_error` → `test_load_nonexistent_file_shows_welcome_page`
-- Updated assertions to verify welcome page is shown instead of error
-
-## How It Works
-
-### Development Mode
-```
-User runs: python -m webdrop_bridge
-Config: WEBAPP_URL=file:///./webapp/index.html
-Resolution: C:\...\webdrop_bridge\webapp\index.html
-Result: ✅ Loads local webapp from source
-```
-
-### Bundled Executable (PyInstaller)
-```
-User runs: WebDropBridge.exe
-PyInstaller unpacks to: _internal/webapp/
-Resolution logic:
-  1. Try: C:\current\working\dir\webapp\index.html (fails)
-  2. Try: C:\path\to\executable\webapp\index.html (succeeds!)
-Result: ✅ Loads bundled webapp from PyInstaller bundle
-```
-
-### No Webapp Configured
-```
-User runs: WebDropBridge.exe
-No WEBAPP_URL or file not found
-Display: Beautiful welcome page with instructions
-Result: ✅ Professional fallback instead of error
-```
-
-## Testing
-
-All 99 tests pass:
-- ✅ 99 passed in 2.26s
-- ✅ Coverage: 84%
-
-## User Experience
-
-Before:
-```
-Error
-Web application file not found: C:\...\file:\webapp\index.html
-```
-
-After:
-```
-🌉 WebDrop Bridge

-```
-
-## Technical Notes
-
-- CSS selectors escaped with double braces `{{ }}` for `.format()` compatibility
-- Works with both relative paths (`./webapp/`) and absolute paths
-- Handles `file://` URLs and raw file paths
-- Graceful fallback when webapp is missing
-- Professional welcome page generates on-the-fly from template

+# Angular CDK Drag & Drop Analysis - GlobalDAM
+
+## Framework Detection
+
+**Web Application:** Agravity GlobalDAM  
+**Framework:** Angular 19.2.14  
+**Drag & Drop:** Angular CDK (Component Dev Kit)  
+**Styling:** TailwindCSS
+
+## Technical Findings
+
+### 1. Angular CDK Implementation
+
+```html
+<!-- Drag Group (oberste Ebene) -->
+<div cdkdroplistgroup="" aydnd="" class="flex h-full flex-col">
+  
+  <!-- Drop Zone (Collections) -->
+  <div cdkdroplist="" class="cdk-drop-list" id="collectioncsuaaDVNokl0...">
+    
+    <!-- Draggable Element (Asset Card) -->
+    <li cdkdrag="" class="cdk-drag asset-list-item" draggable="false">
+      <img src="./GlobalDAM JRI_files/anPGZszKzgKaSz1SIx2HFgduy" 
+           alt="weiss_ORIGINAL">
+    </li>
+  </div>
+</div>
+```
+
+### 2. Key Observations
+
+#### Native HTML5 Drag ist DEAKTIVIERT
+```html
+draggable="false"
+```
+
+**Bedeutung:**
+- Kein Zugriff auf native `dragstart`, `drag`, `dragend` Events
+- Kein `event.dataTransfer` API verfügbar
+- Angular CDK simuliert Drag & Drop komplett in JavaScript
+- Daten werden NICHT über natives Clipboard/DataTransfer übertragen
+
+#### Angular CDK Direktiven
+- `cdkdroplistgroup` - Gruppiert mehrere Drop-Zonen
+- `cdkdroplist` - Markiert Drop-Bereiche (Collections, Clipboard)
+- `cdkdrag` - Markiert draggbare Elemente (Assets)
+- `cdkdroplistsortingdisabled` - Sortierung deaktiviert
+
+#### Asset Identifikation
+```html
+<!-- Asset ID im Element-ID -->
+<div id="anPGZszKzgKaSz1SIx2HFgduy">
+
+<!-- Asset ID in der Bild-URL -->
+<img src="./GlobalDAM JRI_files/anPGZszKzgKaSz1SIx2HFgduy">
+
+<!-- Asset Name im alt-Attribut -->
+<img alt="weiss_ORIGINAL">
+```
+
+## Impact on WebDrop Bridge
+
+### ❌ Bisheriger Ansatz funktioniert NICHT
+
+Unser aktueller Ansatz basiert auf:
+1. Interception von nativen Drag-Events
+2. Manipulation von `event.dataTransfer.effectAllowed` und `.dropEffect`
+3. Setzen von URLs im DataTransfer
+
+**Das funktioniert NICHT mit Angular CDK**, da:
+- Angular CDK das native Drag & Drop komplett umgeht
+- Keine nativen Events gefeuert werden
+- DataTransfer API nicht verwendet wird
+
+### ✅ Mögliche Lösungsansätze
+
+#### Ansatz 1: JavaScript Injection zur Laufzeit
+Injiziere JavaScript-Code, der Angular CDK Events abfängt:
+
+```javascript
+// Überwache Angular CDK Event-Handler
+document.addEventListener('cdkDragStarted', (event) => {
+  const assetId = event.source.element.nativeElement.id;
+  const assetName = event.source.element.nativeElement.querySelector('img')?.alt;
+  
+  // Sende an Qt WebChannel
+  bridge.handleDragStart(assetId, assetName);
+});
+
+document.addEventListener('cdkDragDropped', (event) => {
+  // Verhindere das Standard-Verhalten
+  event.preventDefault();
+  
+  // Starte nativen Drag von Qt aus
+  bridge.initNativeDrag();
+});
+```
+
+**Vorteile:**
+- ✅ Direkter Zugriff auf Angular CDK Events
+- ✅ Kann Asset-Informationen extrahieren
+- ✅ Kann Drag-Operationen abfangen
+
+**Nachteile:**
+- ⚠️ Erfordert genaue Kenntnis der Angular CDK Internals
+- ⚠️ Könnte bei Angular CDK Updates brechen
+- ⚠️ Komplexer zu implementieren
+
+#### Ansatz 2: DOM Mutation Observer
+Überwache DOM-Änderungen während des Drags:
+
+```javascript
+const observer = new MutationObserver((mutations) => {
+  mutations.forEach((mutation) => {
+    // Suche nach CDK Drag-Elementen mit bestimmten Klassen
+    const dragElement = document.querySelector('.cdk-drag-preview');
+    if (dragElement) {
+      const assetId = dragElement.querySelector('[id^="a"]')?.id;
+      bridge.handleDrag(assetId);
+    }
+  });
+});
+
+observer.observe(document.body, {
+  childList: true,
+  subtree: true,
+  attributes: true,
+  attributeFilter: ['class']
+});
+```
+
+**Vorteile:**
+- ✅ Robuster gegenüber Framework-Updates
+- ✅ Funktioniert mit beliebigen Frameworks
+
+**Nachteile:**
+- ⚠️ Performance-Overhead
+- ⚠️ Kann falsche Positive erzeugen
+
+#### Ansatz 3: Qt WebChannel Bridge mit Custom Events
+Nutze Qt WebChannel, um mit der Angular-Anwendung zu kommunizieren:
+
+```python
+# Python-Seite (Qt)
+class DragBridge(QObject):
+    @Slot(str, str)
+    def onAssetDragStart(self, asset_id: str, asset_name: str):
+        """Called from JavaScript when Angular CDK drag starts."""
+        logger.info(f"Asset drag started: {asset_id} ({asset_name})")
+        self.convert_and_drag(asset_id, asset_name)
+```
+
+```javascript
+// JavaScript-Seite (injiziert via QWebEngineScript)
+new QWebChannel(qt.webChannelTransport, (channel) => {
+  const dragBridge = channel.objects.dragBridge;
+  
+  // Monkey-patch Angular CDK's DragRef
+  const originalStartDraggingSequence = CdkDrag.prototype._startDraggingSequence;
+  CdkDrag.prototype._startDraggingSequence = function(event) {
+    const assetElement = this.element.nativeElement;
+    const assetId = assetElement.id;
+    const assetName = assetElement.querySelector('img')?.alt;
+    
+    // Benachrichtige Qt
+    dragBridge.onAssetDragStart(assetId, assetName);
+    
+    // Rufe original Angular CDK Methode auf
+    return originalStartDraggingSequence.call(this, event);
+  };
+});
+```
+
+**Vorteile:**
+- ✅ Saubere Kommunikation zwischen Qt und Web
+- ✅ Kann Asset-Informationen zuverlässig extrahieren
+- ✅ Typensicher (Qt Signals/Slots)
+
+**Nachteile:**
+- ⚠️ Erfordert Monkey-Patching von Angular CDK
+- ⚠️ Kann bei CDK Updates brechen
+
+#### Ansatz 4: Browser DevTools Protocol (Chrome DevTools)
+Nutze Chrome DevTools Protocol für tiefere Integration:
+
+```python
+from PySide6.QtWebEngineCore import QWebEngineProfile
+
+profile = QWebEngineProfile.defaultProfile()
+profile.setRequestInterceptor(...)
+
+# Intercepte Netzwerk-Requests und injiziere Header
+# Überwache JavaScript-Execution via CDP
+```
+
+**Vorteile:**
+- ✅ Sehr mächtig, kann JavaScript-Execution überwachen
+- ✅ Kann Events auf niedrigerer Ebene abfangen
+
+**Nachteile:**
+- ⚠️ Sehr komplex
+- ⚠️ Erfordert Chrome DevTools Protocol Kenntnisse
+- ⚠️ Performance-Overhead
+
+## Empfohlener Ansatz
+
+### **Ansatz 3: Qt WebChannel Bridge** (BEVORZUGT)
+
+**Begründung:**
+1. ✅ Saubere Architektur mit klarer Trennung
+2. ✅ Typsicher durch Qt Signals/Slots
+3. ✅ Kann Asset-IDs und -Namen zuverlässig extrahieren
+4. ✅ Funktioniert auch wenn Angular CDK interne Änderungen hat
+5. ✅ Ermöglicht bidirektionale Kommunikation
+
+**Implementierungsschritte:**
+
+### Phase 1: Asset-Informationen extrahieren
+1. JavaScript via QWebEngineScript injizieren
+2. Qt WebChannel setuppen
+3. Angular CDK Events überwachen (ohne Monkey-Patching als Test)
+4. Asset-IDs und Namen an Qt senden
+
+### Phase 2: Native Drag initiieren
+1. Bei CDK Drag-Start: Extrahiere Asset-Informationen
+2. Sende Asset-ID an Backend/API
+3. Erhalte lokalen Dateipfad oder Azure Blob URL
+4. Konvertiere zu lokalem Pfad (wie aktuell)
+5. Initiiere nativen Drag mit QDrag
+
+### Phase 3: Drag-Feedback
+1. Zeige Drag-Preview in Qt (optional)
+2. Update Cursor während Drag
+3. Cleanup nach Drag-Ende
+
+## Asset-ID zu Dateipfad Mapping
+
+Die Anwendung verwendet Asset-IDs in mehreren Formaten:
+
+```javascript
+// Asset-ID: anPGZszKzgKaSz1SIx2HFgduy
+
+// Mögliche URL-Konstruktion:
+const assetUrl = `https://dev.agravity.io/api/assets/${assetId}`;
+const downloadUrl = `https://dev.agravity.io/api/assets/${assetId}/download`;
+const blobUrl = `https://static.agravity.io/${workspaceId}/${assetId}/${filename}`;
+```
+
+**Für WebDrop Bridge:**
+- Asset-ID aus DOM extrahieren
+- Asset-Metadaten via API abrufen (falls verfügbar)
+- Blob-URL konstruieren
+- URL Converter nutzen (bereits implementiert!)
+
+## Next Steps
+
+1. **Proof of Concept**: Qt WebChannel mit einfachem Event-Logger
+2. **Asset-ID Extraction**: JavaScript Injection testen
+3. **API Research**: GlobalDAM API untersuchen (Asset-Metadaten)
+4. **Integration**: Mit bestehendem URLConverter verbinden
+5. **Testing**: Mit echten Assets testen
+
+## Hinweise
+
+- Angular CDK Version kann sich unterscheiden - Code muss robust sein
+- Asset-IDs scheinen eindeutig zu sein (Base64-ähnlich)
+- Die Anwendung nutzt Azure Blob Storage (basierend auf bisherigen URLs)
+- Custom Components (`ay-*`) deuten auf eine eigene Component Library hin

+# Drag & Drop Problem Analysis - File Drop + Web App Popup
+
+## Das Kernproblem
+
+**Ziel**: Bei ALT-Drag soll:
+1. ✅ File gedroppt werden (Z:\ Laufwerk) → Native File-Drop
+2. ✅ Web-App Popup erscheinen (Auschecken-Dialog) → Web-App Drop-Event
+
+**Problem**: Diese beiden schließen sich gegenseitig aus:
+- Native File-Drag (von Qt) → Web-App bekommt kein Drop-Event → Kein Popup
+- Browser Text-Drag (von Web-App) → Kein File-Drop → Kein File
+
+## Browser-Sicherheitsbeschränkungen
+
+1. **DataTransfer.files ist read-only**  
+   Wir können keine Files zu einem DataTransfer hinzufügen
+
+2. **Nur EIN Drag zur Zeit möglich**  
+   Wir können keinen parallelen Drag starten
+
+3. **DataTransfer kann nicht erstellt werden**  
+   Wir können kein synthetisches Drop-Event mit Files erzeugen
+
+4. **Cross-Domain Sicherheit**  
+   File-Zugriff ist stark eingeschränkt
+
+## Getestete Ansätze
+
+### ❌ Ansatz 1: DataTransfer erweitern
+**Idee**: Web-App setzt URL, wir fügen Files hinzu  
+**Problem**: DataTransfer.files ist read-only
+
+### ❌ Ansatz 2: Parallele Drags
+**Idee**: Browser-Drag + Qt-Drag gleichzeitig  
+**Problem**: Nur ein Drag zur Zeit möglich
+
+### ❌ Ansatz 3: Synthetisches Drop-Event
+**Idee**: Original Drop abfangen, neues Event mit Files erzeugen  
+**Problem**: DataTransfer.files kann nicht gesetzt werden
+
+### ⚠️ Ansatz 4: Native Drag + Event-Simulation
+**Idee**: Qt Native Drag, dann Web-App Event manuell auslösen  
+**Problem**: Erfordert Kenntnis der exakten Web-App Event-Struktur (Angular CDK)
+
+## 🎯 Praktikable Lösungen
+
+### Lösung A: **Zwei-Phasen Ansatz** (EMPFOHLEN für Testing)
+
+**Phase 1: File-Drop**
+1. ALT-Drag startet
+2. JavaScript erkennt convertible URL
+3. Ruft Qt's `start_file_drag(url)` auf
+4. `preventDefault()` verhindert Browser-Drag
+5. Qt Native Drag läuft
+6. File wird gedroppt ✅
+
+**Phase 2: Popup manuell triggern**
+7. Nach erfolgreichem Drop (via Qt Signal)
+8. JavaScript simuliert den Event/API-Call der das Popup auslöst
+9. Popup erscheint ✅
+
+**Vorteile:**
+- ✅ Funktioniert garantiert für File-Drop
+- ✅ Kontrolle über beide Phasen
+- ✅ Kann debugged werden
+
+**Nachteile:**
+- ⚠️ Erfordert Reverse-Engineering des Popup-Triggers
+- ⚠️ Könnte bei Web-App Updates brechen
+
+**Implementierung:**
+```javascript
+// Phase 1: Standard - File Drag
+document.addEventListener('dragstart', function(e) {
+  if (!e.altKey) return;
+  
+  // Extract URL from DataTransfer
+  var url = e.dataTransfer.getData('text/plain');
+  if (isConvertible(url)) {
+    e.preventDefault();
+    window.bridge.start_file_drag(url);
+  }
+}, true);
+
+// Phase 2: Popup Trigger (nach Drop-Erfolg)
+// Qt ruft auf: window.trigger_checkout_popup(assetId)
+window.trigger_checkout_popup = function(assetId) {
+  // Option 1: Klick auf Checkout-Button simulieren
+  // Option 2: API-Call direkt aufrufen
+  // Option 3: Angular-Event dispatchen
+  
+  // Beispiel: Suche nach Angular-Component und rufe Methode auf
+  var angularComponent = findAngularComponent('ay-asset-card');
+  if (angularComponent) {
+    angularComponent.onCheckout(assetId);
+  }
+};
+```
+
+**TODO für diese Lösung:**
+1. ✅ File-Drag funktioniert bereits
+2. ⏸️ Herausfinden wie Popup ausgelöst wird:
+   - Browser DevTools öffnen
+   - Network-Tab beobachten (API-Call?)
+   - Elements-Tab nutzen (Angular Component?)
+   - Event-Listeners ansehen
+
+### Lösung B: **Gar nichts ändern beim Drag** (FALLBACK)
+
+**Ansatz:**
+1. ALT-Drag läuft normal durch (URL-Text wird gedroppt)
+2. Popup erscheint ✅
+3. Nach Popup-Bestätigung (Auschecken)
+4. **DANN** konvertieren wir die URL und kopieren das File
+
+**Vorteile:**
+- ✅ Web-App funktioniert normal
+- ✅ Kein Popup-Problem
+- ✅ Einfach zu implementieren
+
+**Nachteile:**
+- ⚠️ Kein echter Drag & Drop (nur Copy)
+- ⚠️ User muss zweimal handeln
+
+### Lösung C: **File-Drop via Qt Window Overlay** (EXPERIMENTELL)
+
+**Ansatz:**
+1. Beim ALT-Drag: Start Normal Web-App Drag
+2. Qt erstellt ein transparentes Overlay-Window über dem Browser
+3. Overlay fängt das Drop-Event ab
+4. Qt macht File-Drop
+5. Qt leitet Drop-Koordinaten an Browser weiter
+6. Browser bekommt synthetisches Event (ohne Files, nur Koordinaten)
+7. Popup erscheint
+
+**Vorteile:**
+- ✅ Beide Funktionen potentiell möglich
+- ✅ Keine DataTransfer-Manipulation nötig
+
+**Nachteile:**
+- ⚠️ Sehr komplex
+- ⚠️ Plattform-spezifisch (Windows)
+- ⚠️ Performance-Overhead
+
+## 🔬 Nächste Schritte - Reverse Engineering
+
+Um Lösung A zu implementieren, müssen wir herausfinden:
+
+### 1. Wie wird das Popup ausgelöst?
+
+**Debug-Schritte:**
+```javascript
+// In Browser Console ausführen während ALT-Drag+Drop
+
+// Methode 1: Event-Listener finden
+getEventListeners(document)
+
+// Methode 2: Angular Component finden
+var cards = document.querySelectorAll('ay-asset-card');
+var component = ng.getComponent(cards[0]); // Angular DevTools
+console.log(component);
+
+// Methode 3: Network-Tab
+// Schauen ob API-Call gemacht wird nach Drop
+```
+
+**Erwartete Möglichkeiten:**
+- API-Call zu `/api/assets/{id}/checkout`
+- Angular Event: `cdkDropListDropped`
+- Component-Methode: `onAssetDropped()` oder ähnlich
+- Modal-Service: `ModalService.show('checkout-dialog')`
+
+### 2. Asset-ID extrahieren
+
+Die Asset-ID wird benötigt für den Popup-Trigger:
+
+```javascript
+// Asset-ID ist wahrscheinlich in:
+// - Element-ID: "anPGZszKzgKaSz1SIx2HFgduy"
+// - Image-URL: "./GlobalDAM JRI_files/anPGZszKzgKaSz1SIx2HFgduy"
+// - Data-Attribut: data-asset-id
+
+function extractAssetId(element) {
+  // Aus Element-ID
+  if (element.id && element.id.match(/^a[A-Za-z0-9_-]+$/)) {
+    return element.id;
+  }
+  
+  // Aus Bild-URL
+  var img = element.querySelector('img');
+  if (img && img.src) {
+    var match = img.src.match(/([A-Za-z0-9_-]{20,})/);
+    if (match) return match[1];
+  }
+  
+  return null;
+}
+```
+
+### 3. Popup programmatisch öffnen
+
+Sobald wir wissen wie, implementieren wir:
+
+```python
+# Python (Qt)
+class DragBridge(QObject):
+    @Slot(str)
+    def on_file_dropped_success(self, local_path: str):
+        """Called after successful file drop."""
+        # Extrahiere Asset-ID aus Pfad oder URL-Mapping
+        asset_id = self.extract_asset_id(local_path)
+        
+        # Trigger Popup via JavaScript
+        js_code = f"window.trigger_checkout_popup('{asset_id}')"
+        self.web_view.page().runJavaScript(js_code)
+```
+
+## ⚡ Quick Win: Debugging aktivieren
+
+Fügen Sie zu **allen** JavaScript-Varianten umfangreiches Logging hinzu:
+
+```javascript
+// In bridge_script.js
+
+// Log ALLE Events
+['dragstart', 'drag', 'dragenter', 'dragover', 'drop', 'dragend'].forEach(function(eventName) {
+  document.addEventListener(eventName, function(e) {
+    console.log('[DEBUG]', eventName, {
+      target: e.target.tagName,
+      dataTransfer: {
+        types: e.dataTransfer.types,
+        effectAllowed: e.dataTransfer.effectAllowed,
+        dropEffect: e.dataTransfer.dropEffect
+      },
+      altKey: e.altKey,
+      coordinates: {x: e.clientX, y: e.clientY}
+    });
+  }, true);
+});
+
+// Log DataTransfer Zugriffe
+Object.defineProperty(DataTransfer.prototype, 'types', {
+  get: function() {
+    var types = this._types || [];
+    console.log('[DEBUG] DataTransfer.types accessed:', types);
+    return types;
+  }
+});
+```
+
+## 📝 Empfehlung
+
+**Sofortige Maßnahmen:**
+
+1. ✅ **Lösung A Phase 1 ist bereits implementiert** (File-Drop funktioniert)
+
+2. 🔍 **Reverse-Engineering durchführen:**
+   - GlobalDAM JRI im Browser öffnen
+   - DevTools öffnen (F12)
+   - ALT-Drag+Drop durchführen
+   - Beobachten:
+     - Network-Tab → API-Calls?
+     - Console → Fehler/Logs?
+     - Angular DevTools → Component-Events?
+
+3. 🛠️ **Popup-Trigger implementieren:**
+   - Sobald bekannt WIE Popup ausgelöst wird
+   - JavaScript-Funktion `trigger_checkout_popup()` erstellen
+   - Von Qt aus nach erfolgreichem Drop aufrufen
+
+4. 🧪 **Testen:**
+   - ALT-Drag eines Assets
+   - File-Drop sollte funktionieren
+   - Popup sollte erscheinen
+
+**Fallback:**
+Falls Reverse-Engineering zu komplex ist → **Lösung B** verwenden (Kein Drag, nur Copy nach Popup-Bestätigung)

-The update feature hang issue has been fixed by:
-
-1. Created UpdateDownloadWorker class that runs async operations in a

-
-2. The worker properly handles:
-   - Downloading the update asynchronously
-   - Verifying checksums asynchronously  
-   - Emitting signals for UI updates
-
-3. MainWindow's _perform_update_async() method now:
-   - Creates a background thread for the worker
-   - Connects signals for download complete/failure handlers
-   - Keeps a reference to prevent garbage collection
-   - Properly cleans up threads after completion
-
-Result: The update dialog now displays without freezing the application!
-        The user can interact with the UI while the download happens.
