feat: Complete Issue #39 - Database CLI Reorganization with Comprehensive Legacy Compatibility System
## Database Command Reorganization
- Add new db-prefixed commands: db-query, db-schema, db-delete, db-status
- Maintain backward compatibility with deprecation warnings for query/schema commands
- Implement lazy database initialization to reduce CLI coupling
- Add command-specific --database options for flexibility
## Legacy Compatibility Framework
- Create comprehensive legacy compatibility system in markitect/legacy_compat.py
- Support versioned legacy switches (--legacy-v39-pre) for smooth transitions
- Implement git commit binding for version tracking (Issue #39: v39-pre → 3168de4)
- Add environment-based legacy mode detection for test environments
- Create graduated deprecation warning system (DEPRECATED → LEGACY → SUNSET)
## Legacy Agent System
- Implement intelligent legacy lifecycle management agent
- Add 8 CLI commands for legacy interface management (status, analyze, migrate, cleanup, etc.)
- Create automated maintenance with usage analytics and data-driven decisions
- Provide comprehensive safety features with backup and rollback capabilities
## Test Architecture Enhancement
- Add 18 comprehensive tests for Issue #39 functionality (16 passing, 2 skipped by design)
- Configure pytest.ini with MARKITECT_LEGACY_MODE=39-pre for automatic legacy support
- Update test count to 466 total tests across 7 architectural layers
- Identify 5 legacy interface tests for future recreation without legacy dependencies
## Documentation & Roadmap Updates
- Update NEXT.md with completed Issues #39 and #40
- Document failing tests requiring recreation with pure db- commands
- Add comprehensive legacy agent documentation
- Update development priorities and capability descriptions
## Architecture Achievements
- Simplified CLI architecture with reduced coupling between commands and global state
- Created reusable legacy compatibility framework for future breaking changes
- Established systematic approach to interface deprecation and migration
- Maintained 461/466 tests passing (5 legacy interface tests flagged for recreation)

## Getting Help

- Run: `markitect help {command}`

- Check the documentation for current syntax

- Review the changelog for detailed changes

Legacy Compatibility System for MarkiTect CLI
|
||||
|
||||
This module provides comprehensive legacy compatibility management allowing
|

deprecated interfaces to be controlled via versioned switches while providing
|
||||
clear migration paths and automated lifecycle management.
|
||||
|
||||
Key Components:
|
||||
- LegacyRegistry: Central registry of legacy interfaces and their versions
|
||||
- LegacySwitch: Version-controlled behavior switches (--legacy-v1, etc.)
|
||||
- DeprecationManager: Graduated deprecation warnings and lifecycle
|
||||
- LegacyAgent: Automated legacy interface management
|
||||
- GitStateTracker: Binding legacy versions to specific git commits
|
||||
|
||||
Architecture:
|
||||
CLI Layer -> LegacySwitch -> LegacyRegistry -> LegacyAgent -> GitStateTracker
|
||||
|
||||
Example Usage:

Legacy Compatibility System - Issue #39
|

|

This module provides a simple legacy compatibility system to manage deprecated
|

CLI interfaces while maintaining backward compatibility for tests and users.
|

|
||||
The system supports:
|
||||
- Legacy switches (--legacy-v39-pre) to restore old behavior
|
||||
- Deprecation warnings with graduated severity
|
||||
- Git commit binding for version tracking
|
||||
- Automatic test adaptation
