This commit closes the schema-evolution topic (260105) by adding the final
deliverable (ADR schema) and fixing markdown schema support across commands.
**ADR Schema Created**:
- Comprehensive Architecture Decision Record validation schema
- 12 section classifications (7 required, 2 recommended, 2 optional, 3 improper/discouraged)
- Content pattern validation for ADR formatting rules (status dates, decision statements, rationale structure)
- Quality metrics for completeness (word counts, sentence counts)
- Follows title case naming convention (Status, Context, Decision, etc.)
**Markdown Schema Support Fixed**:
- Fixed `markitect validate` command to support .md schemas
- Added load_schema_from_path() for both .json and .md files
- Updated structural and semantic validation to use schema dict
- Fixed `markitect generate-stub` command to support .md schemas
- Uses load_schema_from_path() instead of direct JSON loading
- Created DocumentWrapper class in semantic_validator.py
- Extracts headings from AST tokens (heading_open, inline)
- Provides get_headings_by_level() interface expected by validators
- Enables section validation to work with real documents
**Topic Closure**:
- Updated SCHEMA_EVOLUTION_WORKPLAN.md with completion summary
- Phases 1-3: 100% complete (via Schema-of-Schemas and Semantic Validation)
- Phase 4: Deferred as future enhancement (15-20 sessions)
- Phase 5: 70% complete (docs done, CI/CD templates deferred)
- Created DONE.md with comprehensive task checklist
- Generated ADR template stub (examples/templates/adr-template.md)
- Moved topic from roadmap/ to history/260105-schema-evolution/
**Files Changed**:
- markitect/cli.py: Added markdown schema support to validate and generate-stub
- markitect/semantic_validator.py: Added DocumentWrapper class for AST parsing
- markitect/schemas/adr-schema-v1.0.md: New ADR validation schema (560 lines)
- examples/templates/adr-template.md: Generated ADR template stub
- history/260105-schema-evolution/: Moved completed topic to history
**Status**: Schema evolution topic successfully closed with ADR schema as final deliverable.
All schema commands now support markdown schemas. Section validation working correctly.
