+**MANDATORY**: Create backup before ANY code changes:
+```bash
+./create_full_backup.sh
+```
+- Creates full server backup and pushes to GitHub automatically
+- Local copy remains for quick rollback
+- Restore if needed: `./restore_full_backup.sh server_backup_YYYYMMDD_HHMMSS`
+
+### 2. GITHUB BACKUPS ARE PERMANENT
+- **NEVER DELETE** backups from GitHub repository (hetzner-backup)
+- Only local backups can be deleted after successful upload
+- GitHub serves as permanent backup archive
+
+### 3. BACKUP TROUBLESHOOTING
+If `create_full_backup.sh` fails to push:
+- SSH key configured at: `~/.ssh/github_backup`
+- Fix "Author identity unknown": `git -c user.email="backup@intelsight.de" -c user.name="Backup System" commit -m "..."`
+- Repository: `git@github.com:UserIsMH/hetzner-backup.git`
+
+### 4. BACKUP SCHEDULE
+- Manual backups: Before EVERY change using `./create_full_backup.sh`
+- Automatic backups: Daily at 3:00 AM via Admin Panel
+- Admin Panel backup interface: https://admin-panel-undso.intelsight.de/backups
+
+## SYSTEM OVERVIEW
+
+Production license management system at intelsight.de with:
+- **Admin Panel** (Flask): Web interface for customer/license/resource management
+- **License Server** (FastAPI): API for license validation and heartbeat monitoring  
+- **PostgreSQL**: Database with partitioned tables for performance
+- **Nginx**: SSL termination and routing
+
+## KEY FEATURES
+
+### 1. License Management
+- **Device Limit**: Each license has a `device_limit` (1-10 devices)
+- **Concurrent Sessions**: Each license has a `concurrent_sessions_limit` (max simultaneous users)
+- **Constraint**: concurrent_sessions_limit ≤ device_limit
+- **Resource Allocation**: Domains, IPv4 addresses, phone numbers per license
+
+### 2. Device Management
+- **Single Table**: `device_registrations` stores all device information
+- **Device Fields**: `hardware_fingerprint` (unique ID), `device_name`, `device_type`
+- **Tracking**: First activation, last seen, active status
+- **No automatic termination**: When session limit reached, new sessions are denied
+
+### 3. Authentication & Security
+- **API Authentication**: X-API-Key header (format: AF-YYYY-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX)
+- **API Key Management**: Admin Panel → "Lizenzserver Administration" → "System-API-Key generieren"
+- **2FA Support**: TOTP-based two-factor authentication for admin users
+- **Audit Logging**: All changes tracked in audit_log table
+
+### 4. Session Management
+- **Heartbeat**: 30-second intervals (configurable)
+- **Timeout**: 60 seconds without heartbeat = automatic cleanup
+- **Single Device Resume**: Same device can resume existing session
+- **Session Token**: UUID v4 for session identification
+
+### 5. Database Structure
+- **Partitioned Tables**: license_heartbeats (monthly partitions)
+- **Resource Pools**: Centralized management of domains/IPs/phones
+- **Session History**: Complete tracking with end reasons
+- **Lead CRM**: Institution and contact management system

+# Resource Management API Implementation Plan
+
+## Executive Summary
+
+This plan outlines the implementation of a **Dynamic Resource Pool API** for the License Server that allows client applications to:
+1. View available resources from their license's pool
+2. Reserve resources for their active session
+3. Automatically release resources when session ends
+4. Prevent resource conflicts between concurrent sessions
+
+The system works like a "hotel room" model - resources are assigned to a license (the hotel), but individual sessions (guests) reserve specific resources during their stay.
+
+## Current State Analysis
+
+### Existing Infrastructure
+- **Database**: Complete resource management tables (`resource_pools`, `license_resources`, `resource_history`)
+- **Admin Panel**: Full CRUD operations for resource management
+- **License Server**: No resource endpoints (critical gap)
+- **Resource Types**: domain, ipv4, phone
+- **Limits**: 0-10 resources per type per license
+
+### Gap Analysis
+- Clients cannot retrieve their assigned resources
+- No validation endpoint for resource ownership
+- Resource data not included in license activation/verification
+
+## Proposed API Architecture
+
+### Resource Pool Concept
+
+**Key Principles**: 
+- Resources belong to a license pool, but reservation rules differ by type
+- **Domains**: Can be shared (soft reservation) - prefer free, but allow sharing
+- **IPv4 & Phone**: Exclusive use (hard reservation) - one session only
+
+```
+License Pool (Admin-defined)
+├── 5 Domains total
+│   ├── 2 Used by Session A (can be shared)
+│   ├── 1 Used by Session B (can be shared)
+│   ├── 1 Used by both A & B (shared)
+│   └── 1 Completely free
+├── 3 IPv4 Addresses total
+│   ├── 1 Reserved by Session A (exclusive)
+│   └── 2 Available
+└── 2 Phone Numbers total
+    ├── 1 Reserved by Session B (exclusive)
+    └── 1 Available
+```
+
+**Reservation Rules**:
+- **Domains**: `prefer_exclusive = true` - Try to get unused domain first, but allow sharing if needed
+- **IPv4**: `exclusive_only = true` - Fail if none available
+- **Phone**: `exclusive_only = true` - Fail if none available
+

+    "ipv4_addresses": 1,
+    "phone_numbers": 0
+  }
+}
+```
+
+## Implementation Strategy
+
+### Phase 1: Database Schema Extension
+
+1. **New Table: resource_reservations**
+   ```sql
+   CREATE TABLE resource_reservations (
+       id SERIAL PRIMARY KEY,
+       resource_id INTEGER REFERENCES resource_pools(id) ON DELETE CASCADE,
+       session_token VARCHAR(255) NOT NULL,
+       license_id INTEGER REFERENCES licenses(id) ON DELETE CASCADE,
+       reserved_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+       last_accessed TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+       UNIQUE(resource_id, session_token)
+   );
+   
+   CREATE INDEX idx_reservations_session ON resource_reservations(session_token);
+   CREATE INDEX idx_reservations_resource ON resource_reservations(resource_id);
+   
+   -- View for usage counts
+   CREATE VIEW resource_usage_counts AS
+   SELECT 
+       rp.id,
+       rp.resource_type,
+       rp.resource_value,
+       COUNT(rr.id) as usage_count,
+       CASE 
+           WHEN rp.resource_type = 'domain' AND COUNT(rr.id) > 0 THEN true
+           ELSE false
+       END as is_shared
+   FROM resource_pools rp
+   LEFT JOIN resource_reservations rr ON rp.id = rr.resource_id
+   WHERE rp.status = 'allocated'
+   GROUP BY rp.id, rp.resource_type, rp.resource_value;
+   ```
+
+2. **Automatic Cleanup Trigger**
+   ```sql
+   -- When session ends, release all reserved resources
+   CREATE OR REPLACE FUNCTION release_session_resources()
+   RETURNS TRIGGER AS $$
+   BEGIN
+       DELETE FROM resource_reservations 
+       WHERE session_token = OLD.session_token;
+       RETURN OLD;
+   END;
+   $$ LANGUAGE plpgsql;
+   
+   CREATE TRIGGER cleanup_session_resources
+   AFTER DELETE ON license_sessions
+   FOR EACH ROW EXECUTE FUNCTION release_session_resources();
+   ```
+
+### Phase 2: License Server Backend (Week 1)
+
+1. **Create Resource Models** (`v2_lizenzserver/app/models/resource.py`)
+   ```python
+   class ResourceReservation(BaseModel):
+       id: int
+       resource_id: int
+       resource_type: ResourceType
+       value: str
+       session_token: str
+       reserved_at: datetime
+       
+   class PoolStatus(BaseModel):
+       total: int
+       reserved: int
+       available: int
+       reserved_by_you: int
+   ```
+
+2. **Create Resource Schemas** (`v2_lizenzserver/app/schemas/resource.py`)
+   ```python
+   class ResourcesResponse(BaseModel):
+       success: bool
+       resources: Dict[str, List[AssignedResource]]
+       limits: Dict[str, int]
+   ```
+
+3. **Create Resource Service** (`v2_lizenzserver/app/services/resource_service.py`)
+   - Query resource_pools and license_resources tables
+   - Implement caching for performance
+   - Add resource validation logic
+
+4. **Create Resource API Routes** (`v2_lizenzserver/app/api/resource.py`)
+   - Implement all new endpoints
+   - Add proper error handling
+   - Include rate limiting
+
+### Phase 2: Security & Authentication (Week 1)
+
+1. **Multi-Factor Authentication**
+   - Require API Key + License Key + Session Token
+   - Validate session is active and belongs to license
+   - Rate limit: 100 requests/minute per license
+
+2. **Data Access Control**
+   - Resources only visible to owning license
+   - No cross-license data leakage
+   - Audit log all resource API access
+
+3. **Caching Strategy**
+   - Cache resource assignments for 5 minutes
+   - Invalidate on Admin Panel changes
+   - Use Redis if available, in-memory fallback
+
+### Phase 3: Integration & Testing (Week 2)
+
+1. **Integration Tests**
+   - Test all resource endpoints
+   - Verify security boundaries
+   - Load test with multiple concurrent requests
+
+2. **Client SDK Updates**
+   - Update Python client example
+   - Update C# client example
+   - Create resource caching example
+
+3. **Documentation**
+   - Update API_REFERENCE.md
+   - Create resource API examples
+   - Add troubleshooting guide
+
+### Phase 4: Monitoring & Optimization (Week 2)
+
+1. **Metrics**
+   - Resource API request count
+   - Cache hit/miss ratio
+   - Response time percentiles
+
+2. **Performance Optimization**
+   - Database query optimization
+   - Add indexes if needed
+   - Implement connection pooling
+
+## Security Considerations
+
+1. **Authentication Layers**
+   - API Key (system-level)
+   - License Key (license-level)
+   - Session Token (session-level)
+
+2. **Rate Limiting**
+   - Per-license: 100 req/min
+   - Per-IP: 1000 req/min
+   - Burst allowance: 10 requests
+
+3. **Data Isolation**
+   - Strict license-based filtering
+   - No enumeration attacks possible
+   - Resource IDs not sequential
+
+4. **Audit Trail**
+   - Log all resource API access
+   - Track abnormal access patterns
+   - Alert on suspicious activity
+
+## Client Integration Guide
+
+### Python Example
+```python
+class AccountForgerClient:

+                        break
+        
+        return reserved
+```
+
+### Resource Reservation Flow Example
+```python
+# 1. Start session
+session = client.start_session(license_key)
+
+# 2. Check available resources
+available = client.get_available_resources()
+print(f"Available domains: {available['pool_status']['domains']['available']}")
+
+# 3. Reserve what you need
+if available['available_resources']['domains']:
+    domain = available['available_resources']['domains'][0]
+    client.reserve_resource('domain', domain['id'])
+
+# 4. Use the resources...
+
+# 5. Resources auto-released when session ends
+client.end_session()  # Triggers automatic cleanup
+```
+
+### Handling Resource Conflicts
+```python
+def reserve_with_retry(client, resource_type, resource_id, max_retries=3):
+    """Handle race conditions when multiple sessions reserve simultaneously"""
+    for attempt in range(max_retries):
+        try:

+
+## Database Migrations
+
+### Required Indexes
+```sql
+-- Optimize resource queries
+CREATE INDEX idx_license_resources_active_license 
+ON license_resources(license_id, is_active) 
+WHERE is_active = TRUE;
+
+CREATE INDEX idx_resource_pools_allocated 
+ON resource_pools(allocated_to_license, resource_type) 
+WHERE status = 'allocated';
+```
+
+## Rollout Plan
+
+1. **Week 1**: Backend implementation + Security
+2. **Week 2**: Testing + Client integration
+3. **Week 3**: Staged rollout (10% → 50% → 100%)
+4. **Week 4**: Monitoring + Optimization
+
+## Success Metrics
+
+- API response time < 100ms (p95)
+- Cache hit ratio > 80%
+- Zero security incidents
+- Client adoption > 90% within 30 days
+
+## Risk Mitigation
+
+1. **Performance Risk**: Pre-emptive caching and query optimization
+2. **Security Risk**: Multi-layer authentication and rate limiting
+3. **Compatibility Risk**: Maintain backward compatibility
+4. **Scalability Risk**: Horizontal scaling ready architecture
+
+## Future Enhancements
+
+1. **Webhook Notifications**: Notify clients of resource changes
+2. **Resource Usage Analytics**: Track actual resource utilization
+3. **Dynamic Resource Allocation**: Auto-assign based on usage patterns
+4. **Resource Sharing**: Allow resource sharing between licenses

UserIsMH	ffc6aa744a	Fix version check endpoint authentication Changed version check endpoints to use X-API-Key authentication instead of Bearer token authentication. This makes them consistent with all other license server endpoints. Changes: - Updated /api/version/check to use validate_api_key dependency - Updated /api/version/latest to use validate_api_key dependency - Both endpoints now expect X-API-Key header instead of Authorization Bearer - Fixes HTTP 403 errors reported by client applications This resolves the issue where session heartbeat worked but version check failed with 403 Forbidden. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-07-02 21:37:58 +00:00
