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

Development Efficiency

• Comprehensive Build System: 40+ Makefile targets for all development needs
• Workspace Isolation: Per-developer isolated environments
• Hot Reloading: Development-time hot reloading support

Production Reliability

• Backward Compatibility: All existing functionality preserved
• Hybrid Architecture: Rust orchestrator + Nushell business logic
• Configuration-Driven: Complete migration from ENV to TOML configuration
• Zero-Downtime Deployment: Seamless integration and migration strategies

Extensibility

• Template-Based Development: Comprehensive templates for all extension types
• Type-Safe Configuration: KCL schemas with validation
• Multi-Platform Support: Cross-platform compilation and distribution
• API Versioning: Backward-compatible API evolution

Development Tools

Build System (src/tools/)

• Makefile: 40+ targets for comprehensive build management
• Cross-Compilation: Support for Linux, macOS, Windows
• Distribution: Automated package generation and validation
• Release Management: Complete CI/CD integration

Workspace Tools (workspace/tools/)

• workspace.nu: Unified workspace management interface
• Path Resolution: Smart path resolution with workspace awareness
• Health Monitoring: Comprehensive health checks with automatic repairs
• Extension Development: Template-based extension development

Migration Tools

• Configuration Migration: ENV to TOML migration utilities
• Data Migration: Database migration strategies and tools
• Validation: Comprehensive migration validation and verification

Best Practices

Code Quality

• Configuration-Driven: Never hardcode, always configure
• Comprehensive Testing: Unit, integration, and end-to-end testing
• Error Handling: Comprehensive error context and recovery
• Documentation: Self-documenting code with comprehensive guides

Development Process

• Test-First Development: Write tests before implementation
• Incremental Migration: Gradual transition without disruption
• Version Control: Semantic versioning with automated changelog
• Code Review: Comprehensive review process with quality gates

Deployment Strategy

• Blue-Green Deployment: Zero-downtime deployment strategies
• Rolling Updates: Gradual deployment with health validation
• Monitoring: Comprehensive observability and alerting
• Rollback Procedures: Safe rollback and recovery mechanisms

Support and Troubleshooting

Each guide includes comprehensive troubleshooting sections:

• Common Issues: Frequently encountered problems and solutions
• Debug Mode: Comprehensive debugging tools and techniques
• Performance Optimization: Performance tuning and monitoring
• Recovery Procedures: Data recovery and system repair

Contributing

When contributing to provisioning:

1. Follow the Development Workflow Guide
2. Use appropriate Extension Development patterns
3. Ensure Build System compatibility
4. Maintain Integration standards
