# Technical Context

## Architecture Overview

### Stack Components
- **Framework**: Django (MVT Architecture)
- **Frontend**: HTMX + AlpineJS + Tailwind CSS
- **Database**: PostgreSQL with Django ORM
- **Cache**: Redis for application and version control
- **Authentication**: Django Built-in Auth

## Technical Architecture

### Backend (Django)
1. Core Framework Features
   - MVT pattern implementation
   - ORM for data management
   - Template system
   - Authentication & permissions
   - Admin interface
   - URL routing
   - Form processing

2. Data Layer
   - Models & relationships
   - Validation rules
   - Signal handlers
   - Database migrations
   - Version control tracking

3. Version Control System
   - Branching and merging capabilities
   - Change tracking with history
   - Batch processing operations
   - Caching strategy using Redis
   - Performance monitoring
   - Multi-level model versioning

### Frontend Architecture
1. HTMX Integration
   - Dynamic updates
   - Partial page renders
   - Server-side processing
   - Progressive enhancement
   - Version control UI updates

2. AlpineJS Usage
   - UI state management
   - Component behaviors
   - Event handling
   - DOM manipulation
   - Version control interactions

3. Tailwind CSS
   - Utility-first styling
   - Custom theme configuration
   - Responsive design
   - Dark mode support

## Integration Patterns

### Version Control Integration
1. Model Integration
   ```python
   class VersionedModel(HistoricalModel):
       # Base class for version-controlled models
       history = HistoricalRecords()
       version_control = VersionControlManager()
   ```

2. Change Tracking
   ```python
   # Automatic change tracking
   with branch_context(branch):
       model.save()  # Changes tracked in branch
   ```

3. Batch Operations
   ```python
   # Efficient batch processing
   with BatchOperation() as batch:
       batch.process_changes(changes)
   ```

### Template System
1. Structure
   - Base templates
   - Model-specific partials
   - Reusable components
   - Template inheritance
   - Version control components

2. HTMX Patterns
   - Partial updates
   - Server triggers
   - Event handling
   - Response processing
   - Version history display

### State Management
1. Server-side
   - Django sessions
   - Database state
   - Cache management
   - Version control state
   - Branch management

2. Client-side
   - AlpineJS state
   - Local storage
   - HTMX state management
   - Version control UI state

## Performance Requirements
