feat: implement Phase 4 - Schema Migration
Completed Phase 4 of the schema-of-schemas implementation with successful migration of all legacy schemas to the new markdown format following the naming convention. Migration Script (scripts/migrate_schemas.py - 240 lines): - Automated schema migration from JSON to markdown format - Updates version and $id fields to follow conventions - Generates proper frontmatter metadata - Dry-run mode for safe testing - Database cleanup functionality - Comprehensive progress reporting Schemas Migrated (2): - terminology-schema.json → terminology-schema-v1.0.md - Fixed missing version field - Updated $id from /terminology-v1.json to /terminology/v1.0 - Validates successfully against metaschema - api-documentation → api-documentation-schema-v1.0.md - Added version: 1.0.0 - Updated $id to follow /api-documentation/v1.0 format - Validates successfully against metaschema Schemas Deleted (3): - markdown-manpage (duplicate of manpage-schema-v1.0.md) - markdown-manpage-schema.json (duplicate of manpage-schema-v1.0.md) - enhanced-manpage (replaced by manpage-schema-v1.0.md) CLI Enhancement (markitect/cli.py): - Updated schema-ingest to support markdown (.md) files - Auto-detects file type and uses MarkdownSchemaLoader for .md files - Extracts JSON schema from markdown for database storage - Maintains backward compatibility with JSON files Final Schema Registry (4 schemas): ✅ terminology-schema-v1.0.md - Terminology validation ✅ api-documentation-schema-v1.0.md - API documentation structure ✅ manpage-schema-v1.0.md - Unix manual pages ✅ schema-schema-v1.0.md - Metaschema for validating schemas All schemas: - Follow naming convention: {domain}-schema-v{major}.{minor}.md - Include proper frontmatter with schema-id, version, status - Validate successfully against schema-schema-v1.0.md metaschema - Stored in database and ready for use Progress Tracking: - Updated TODO.md with Phase 4 completion - Updated CHANGELOG.md with migration details - Next: Phase 5 - CLI & Documentation Updates 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
