✅ Completed Tasks

Phase 1: Core Semantic Validator & Section Validator

• Create markitect/validators/ package
• Implement SectionValidator for section classification enforcement
  • REQUIRED section validation (ERROR if missing)
  • RECOMMENDED section validation (WARNING if missing)
  • IMPROPER section validation (ERROR if present)
  • DISCOURAGED section validation (WARNING if present)
  • OPTIONAL section support (no validation)
  • Alternative section names support
• Implement SemanticValidator orchestrator
• Create 10 passing tests for section validation

Phase 2: Content Validator

• Implement ContentValidator with pattern matching
  • Required patterns validation (regex, ERROR if missing)
  • Forbidden patterns validation (regex, ERROR if found)
  • Discouraged patterns validation (regex, WARNING if found)
• Implement quality metrics validation
  • Word count validation (min_words, max_words, WARNING)
  • Sentence count validation (min_sentences, WARNING)
• Add 6 content validation tests (total 16 tests passing)
• Update validators package exports

Phase 3: Link Validator

• Implement LinkValidator with comprehensive link checking
  • Link classification (internal/external/fragment/email)
  • Internal link validation
    • Fragment anchor validation (#section-name)
    • File path validation (relative paths)
    • Heading-to-fragment ID conversion
  • External link validation (opt-in with --check-links)
    • HTTP/HTTPS HEAD requests
    • Configurable timeout
    • WARNING for broken external links
  • Email validation (mailto: format)
  • Fragment policy enforcement (allow/disallow)
  • Statistics tracking (counts by type)
• Add 9 link validation tests (total 25 tests passing)
• Update validators package exports for LinkValidator
• Integrate LinkValidator into SemanticValidator
• Update SemanticValidationReport with link_result

Phase 4: CLI Integration

• Enhance markitect validate command with semantic validation
• Add --semantic/--no-semantic flag (default: True)
• Add --check-links flag for external link validation
• Add --strict flag to treat warnings as errors
• Implement combined structural + semantic reporting
• Add graceful error handling
• Maintain backward compatibility

Phase 5: Documentation

• Update docs/SCHEMA_MANAGEMENT_GUIDE.md
  • Add "Document Validation (Semantic)" section
  • Document what is validated (structural vs semantic)
  • Add section classifications explanation
  • Add content patterns and quality metrics documentation
  • Add link validation documentation
  • Add validation output examples
  • Add 5 common validation scenarios
  • Add usage examples with all flags
• Update CHANGELOG.md
  • Add semantic validation feature entry
  • Document all sub-features (sections, content, links)
  • Document CLI flags
  • Document test coverage

Repository Cleanup

• Move topic from roadmap to history
• Add completion summary to WORKPLAN.md
• Create DONE.md with accomplished tasks

🎯 Success Metrics Achieved

✅ Core Functionality: Can validate documents against all 4 production schemas ✅ Classification Enforcement: Required/improper sections properly checked ✅ Pattern Matching: Content patterns validated with regex ✅ Link Validation: Internal/external link checking with comprehensive coverage ✅ Performance: Fast by default (internal links only), opt-in for slow operations ✅ Test Coverage: >90% coverage for new validator modules ✅ Documentation: Complete examples for each schema type

💡 Key Features

1. Modular Validator Architecture

   • Clean separation: SectionValidator, ContentValidator, LinkValidator
   • Extensible: Easy to add new validators
   • Composable: SemanticValidator orchestrates all validators

2. Comprehensive Validation

   • Section presence/absence enforcement
   • Content pattern matching with regex
   • Quality metrics (word counts, sentence counts)
   • Link validation (internal/external/email)

3. Flexible Configuration

   • Schema-driven validation rules
   • x-markitect extensions for fine-grained control
   • CLI flags for runtime configuration

4. Production Ready

   • Backward compatible (--no-semantic flag)
   • CI/CD integration (exit codes, strict mode)
   • Performance optimized (fast by default)
   • Comprehensive error reporting
