2026-01-05 - Phase 5: Enhanced Schema Validation with Multiple Selection

• ✅ Enhanced schema-list command with numbered references in all formats
• ✅ Implemented schema selection parser supporting:

  • Number range: markitect schema-validate 1-3
  • Number list: markitect schema-validate 1,3,5
  • Keyword: markitect schema-validate --all or all
  • Filename: markitect schema-validate schema.md
  • Filesystem path: markitect schema-validate ./schema.md
• ✅ Implemented schema resolution with registry precedence and filesystem fallback
• ✅ Added batch validation with summary table output
• ✅ Added ValidationResult dataclass for structured results
• ✅ Created helper functions: parse_schema_selector, resolve_schema_source, is_filesystem_path, format_validation_summary
• ✅ Maintained full backward compatibility with existing single-file validation
• ✅ Tested all selection methods successfully

Key Features Delivered:

• Number-based schema selection for quick validation
• Batch validation results displayed as clear summary table
• Registry schemas take precedence over filesystem paths
• Helpful error messages with usage examples
• Exit code 0 for success, 1 for validation failures
• Support for future wildcard/globbing expansion

2026-01-04 - Phase 2: Schema Refinement Tools & Terminology Example

• ✅ Implemented schema-analyze command to detect rigidity issues
• ✅ Implemented schema-refine command with automatic loosening logic
• ✅ Added interactive mode to schema-refine for fine-grained control
• ✅ Created comprehensive test suite (33 unit tests, 100% passing)
• ✅ Wrote user guide documentation with examples and workflows
• ✅ Successfully tested on example schemas (reduced rigidity from 60/100 to 24/100)

• api-documentation → api-documentation-schema-v1.0.md

Schemas Deleted:

• markdown-manpage (duplicate)
• markdown-manpage-schema.json (duplicate)

• ✅ schema-schema-v1.0.md (metaschema)

All schemas validate successfully against the metaschema!
