## Architecture Overview
|
||
|
|
|
||
|
|
Provisioning has evolved to support a dual-organization approach:
|
||
|
|
|
||
|
|
- **`src/`**: Development-focused structure with build tools and core components
|
||
|
|
- **`workspace/`**: Development workspace with isolated environments and tools
|
||
|
|
- **Legacy**: Preserved existing functionality for backward compatibility
|
||
|
|
|
||
|
|
## Key Features
