-# Lizenzserver Konfiguration Implementation
-
-## Overview
-✅ COMPLETED: Implemented client configuration management and single-session enforcement for Account Forger software.
-
-## Implementation Status (2025-06-21)
-✅ License activation works (consumes device slots)
-✅ Basic verification exists at `/api/license/verify`
-✅ Heartbeat system implemented (30-second intervals)
-✅ Single-session enforcement implemented
-✅ Admin panel has full UI and backend for "Lizenzserver Konfiguration"
-✅ Session management and monitoring
-✅ Automatic cleanup of expired sessions
-
-## Requirements
-1. **Single Session Enforcement**: Only one device can run the software at a time (even if activated on multiple devices)
-2. **Heartbeat System**: 30-second heartbeats to track active sessions
-3. **Version Management**: Control minimum supported version and update notifications
-4. **Client Configuration**: Manage Account Forger settings from admin panel
-
-## Completed Features
-
-### 1. Database Schema ✅
-
-#### Admin Panel Database
-```sql
--- Client configuration (one row for Account Forger)
-CREATE TABLE client_configs (
-    id SERIAL PRIMARY KEY,
-    client_name VARCHAR(100) NOT NULL DEFAULT 'Account Forger',
-    api_key VARCHAR(255) NOT NULL,
-    heartbeat_interval INTEGER DEFAULT 30, -- seconds
-    session_timeout INTEGER DEFAULT 60, -- seconds (2x heartbeat)
-    current_version VARCHAR(20) NOT NULL,
-    minimum_version VARCHAR(20) NOT NULL,
-    download_url TEXT,
-    whats_new TEXT,
-    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
-);
-
--- Active sessions tracking
-CREATE TABLE active_sessions (
-    id SERIAL PRIMARY KEY,
-    license_id INTEGER REFERENCES licenses(id) ON DELETE CASCADE,
-    hardware_id VARCHAR(255) NOT NULL,
-    ip_address INET,
-    client_version VARCHAR(20),
-    session_token VARCHAR(255) UNIQUE NOT NULL,
-    started_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    last_heartbeat TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    UNIQUE(license_id) -- Only one active session per license
-);
-
--- Session history for debugging
-CREATE TABLE session_history (
-    id SERIAL PRIMARY KEY,
-    license_id INTEGER REFERENCES licenses(id) ON DELETE CASCADE,
-    hardware_id VARCHAR(255) NOT NULL,
-    ip_address INET,
-    client_version VARCHAR(20),
-    started_at TIMESTAMP,
-    ended_at TIMESTAMP,
-    end_reason VARCHAR(50) -- 'normal', 'timeout', 'forced', 'replaced'
-);
-```
-
-### 2. License Server Endpoints ✅
-
-#### Implemented endpoints in `/v2_lizenzserver/app/api/license.py`:
-
-1. **POST /api/license/session/start**
-   - Input: license_key, machine_id, hardware_hash, version
-   - Check: License valid? Already active session?
-   - If active session exists: Return error "Es ist nur eine Sitzung erlaubt, stelle sicher, dass nirgendwo sonst das Programm läuft"
-   - If no session: Create session, return session_token and version info
-   - Response includes: session_token, whats_new (if newer version), download_url
-
-2. **POST /api/license/session/heartbeat**
-   - Input: session_token, license_key
-   - Update last_heartbeat timestamp
-   - Return: success status
-
-3. **POST /api/license/session/end**
-   - Input: session_token
-   - Mark session as ended
-   - Log to session_history
-
-4. **Background job**: Clean up sessions older than 60 seconds without heartbeat
-
-### 3. Admin Panel Implementation ✅
-
-#### Implemented routes in `/v2_adminpanel/routes/admin_routes.py`:
-
-1. **GET /lizenzserver/config**
-   - Show current client configuration
-   - Display active sessions count
-
-2. **POST /lizenzserver/config/update**
-   - Update version, download URL, what's new
-   - Update minimum supported version
-
-3. **GET /lizenzserver/sessions**
-   - List all active sessions
-   - Show: License key, Customer name, Hardware ID, IP, Started at, Last heartbeat
-
-4. **POST /lizenzserver/sessions/{session_id}/terminate**
-   - Force close a session (admin only: rac00n, w@rh@mm3r)
-
-5. **GET /lizenzserver/config/client/new** ✅
-   - Shows client configuration page
-   - Handles initial client config and updates
-
-### 4. Security
-
-- API key required for all client requests
-- License key validates ownership  
-- Hardware ID ensures device authenticity
-- Session tokens prevent replay attacks
-
-### 5. Client Flow
-
-1. **Startup**:
-   ```
-   POST /api/license/session/start
-   -> Get session_token or error
-   -> Show version update if available
-   ```
-
-2. **Running** (every 30 seconds):
-   ```
-   POST /api/license/session/heartbeat
-   -> Keep session alive
-   ```
-
-3. **Shutdown**:
-   ```
-   POST /api/license/session/end
-   -> Clean session exit
-   ```
-
-### 6. Error Handling
-
-- Network interruption: Session expires after 60s
-- Software crash: Session expires after 60s
-- Multiple launch attempts: Show error message
-- Version too old: Block with message to update
-
-### 7. Admin Features
-
-- View active sessions
-- Force terminate sessions
-- Update version requirements
-- View session history (last 24h)
-- Manage client configuration
-
-## Implementation Completed

-1. ✅ Created database tables (client_configs, license_sessions, session_history)
-2. ✅ Implemented session management in license server
-3. ✅ Added heartbeat endpoint
-4. ✅ Created admin panel routes for configuration
-5. ✅ Implemented session viewing/management with terminate capability
-6. ✅ Added background cleanup job (runs every 60 seconds)
-7. ⏳ Ready for testing with Account Forger client
