feat: implement Phase 2 - Markdown Schema Loader

Completed Phase 2 of the schema-of-schemas implementation with full
markdown schema support. This enables schemas to be authored as
markdown files with rich documentation and embedded JSON schemas.

Core Implementation (markitect/schema_loader.py):
- MarkdownSchemaLoader class with comprehensive parsing capabilities
- YAML frontmatter extraction with error handling
- JSON code block extraction with section preference (## Schema Definition)
- Metadata merging with x-markitect-source tracking
- Schema saving with template support and round-trip capability
- Helper methods: list_json_blocks(), validate_schema_structure()

Test Coverage (tests/test_schema_loader.py):
- 35 comprehensive unit tests (100% passing)
- Tests for loading, parsing, saving, round-trip conversion
- Edge case handling (empty files, binary files, malformed blocks)
- Fixed binary file test to use invalid UTF-8 sequences

Example Schema (markitect/schemas/manpage-schema-v1.0.md):
- First markdown schema following naming convention
- Complete manpage schema with frontmatter + documentation + JSON
- Demonstrates section classification and content control
- Shows proper structure for future schema authors

Documentation (roadmap/schema-of-schemas/SCHEMA_LOADER_GUIDE.md):
- Comprehensive user guide (600+ lines)
- API reference with examples
- Best practices and troubleshooting
- Integration patterns for CLI and validator

Progress Tracking:
- Updated TODO.md with Phase 2 completion
- Updated CHANGELOG.md with implementation details
- Next: Phase 3 - Schema-for-Schemas Metaschema

Schema Loader - Extract JSON schemas from markdown files.
This module provides functionality to load schemas from markdown files that
contain embedded JSON schemas in code blocks, along with YAML frontmatter
metadata and rich documentation.

# Schema Title v1.0
## Documentation sections...
## Schema Definition
```json
{

This enables:
- Rich documentation alongside schemas
- Version history in same file
- Human-readable schema files

# Unix Manual Page Schema v1.0
## Overview
This schema defines the structure and validation rules for Unix-style manual pages (manpages) in MarkiTect's markdown format. It includes comprehensive section classification, content control patterns, and quality guidelines to ensure consistent, high-quality documentation.
## Features
- **Section Classification System**: Categorizes manpage sections as required, recommended, optional, discouraged, or improper
- **Content Control**: Validates content patterns, quality metrics, and structural requirements
- **Flexible Section Names**: Supports alternative section names (e.g., "FLAGS" as alternative to "OPTIONS")
- **Quality Enforcement**: Minimum/maximum content requirements for paragraphs, code blocks, and words
## Section Classifications
### Required Sections
- **SYNOPSIS**: Brief command syntax with all options and arguments
- **DESCRIPTION**: Detailed explanation of command purpose and functionality
### Recommended Sections
- **EXAMPLES**: Practical usage examples demonstrating common use cases
- **OPTIONS**: Detailed option descriptions with all flags and behaviors
- **SEE ALSO**: Related commands and documentation references
### Optional Sections
- **BUGS**: Known issues and bug reporting information
- **AUTHORS**: Contributors and maintainers
- **COPYRIGHT**: License information
- **HISTORY**: Historical development information
### Discouraged Sections
- **DEPRECATED**: Legacy content (should move to HISTORY)
- **OLD_SYNTAX**: Outdated syntax (should move to HISTORY or be removed)
### Improper Sections
- **INTERNAL_NOTES**: Development notes (must not appear in published docs)
- **TODO**: Development tasks (remove before publication)
- **DRAFT**: Draft markers (remove before publication)
## Usage
### Validating a Manpage
```bash
markitect validate my-command.1.md --schema manpage-schema-v1.0
```
### Common Validation Errors
1. **Missing Required Sections**: Ensure SYNOPSIS and DESCRIPTION are present
2. **Content Too Brief**: DESCRIPTION should have at least 50 words
3. **No Examples**: While optional, EXAMPLES are highly recommended
4. **Improper Sections**: Remove TODO, DRAFT, and INTERNAL_NOTES before publication
## Content Quality Guidelines
### SYNOPSIS Section
- Show command name in bold: `**command**`
- Use brackets `[]` for optional arguments
- Use italic `*ARG*` for required arguments
- Keep concise (1-5 lines maximum)
- Include 5-150 words
### DESCRIPTION Section
- Start with what the command does
- Explain why users would use it
- Describe main functionality and features
- Minimum 50 words, maximum 1000 words
- At least 3 sentences
### EXAMPLES Section
- Use bash code blocks for commands
- Include comments explaining each example
- Start simple, progress to complex
- Show actual output when helpful
- Cover common use cases first

# Markdown Schema Loader - User Guide
**Version:** 1.0
**Status:** Implemented
**Created:** 2026-01-04
## Overview
The Markdown Schema Loader enables MarkiTect to load JSON schemas from markdown files, combining rich documentation with machine-readable validation rules. This aligns with MarkiTect's markdown-first philosophy while maintaining JSON Schema compatibility.
## Markdown Schema Format
A markdown schema file consists of three parts:
1. **YAML Frontmatter**: Metadata about the schema
2. **Documentation**: Rich markdown content explaining the schema
3. **Schema Definition**: JSON schema in a code block
### Example Structure
```markdown
---
schema-id: "https://markitect.dev/schemas/domain/v1.0"
version: "1.0.0"
status: "stable"
---
# Schema Title v1.0
## Overview
Description of what this schema validates...
## Usage
How to use this schema...
## Schema Definition
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "My Schema",
"type": "object",
...
}
```
## Version History
- v1.0.0 - Initial version
```
## Frontmatter Metadata
### Required Fields
None are strictly required, but these are recommended:
| Field | Type | Description | Example |
|-------|------|-------------|---------|
| `schema-id` | string | Canonical URI for the schema | `https://markitect.dev/schemas/manpage/v1.0` |
| `version` | string | SemVer version | `1.0.0` |
| `status` | string | Lifecycle status | `stable`, `draft`, `deprecated` |
### Optional Fields
| Field | Type | Description |
|-------|------|-------------|
| `domain` | string | Schema domain name |
| `description` | string | Brief schema description |
| `authors` | array | List of authors |
| `created` | string | Creation date (ISO 8601) |
| `updated` | string | Last update date (ISO 8601) |
### Metadata Merging
Frontmatter metadata takes precedence over schema fields:
- `schema-id` → `$id` in the schema
- `version` → `version` in the schema
- `status` → `x-markitect-metadata.status` in the schema
All frontmatter is preserved in `x-markitect-source.frontmatter`.
## JSON Schema Extraction
### Schema Definition Section
The loader prefers JSON blocks under a `## Schema Definition` heading:
```markdown
## Schema Definition
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
...
}
```
```
### Fallback Behavior
If no `## Schema Definition` section exists, the loader uses the **first** JSON code block in the file.
### Multiple JSON Blocks
You can include multiple JSON blocks in documentation:
```markdown
## Example Usage
```json
{
"name": "example",
"version": "1.0"
}
```
## Schema Definition
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
"properties": {
"name": {"type": "string"},
"version": {"type": "string"}
}
}
```
```
The loader will use the schema under `## Schema Definition` heading.
## Using the Loader
### Python API
```python
from pathlib import Path
from markitect.schema_loader import MarkdownSchemaLoader
# Create loader instance
loader = MarkdownSchemaLoader()
# Load schema from markdown
schema_data = loader.load_schema(Path("manpage-schema-v1.0.md"))
# Access components
schema = schema_data['schema'] # JSON Schema dict
metadata = schema_data['metadata'] # Frontmatter dict
docs = schema_data['documentation'] # Full markdown content
source = schema_data['source_file'] # Source file path
# Use the schema
print(f"Loaded: {schema['title']}")
print(f"Version: {schema['version']}")
print(f"Status: {metadata['status']}")
```
### Loading from Markdown
```python
# Load schema
schema_data = loader.load_schema(Path("my-schema-v1.0.md"))
# Check for issues
issues = loader.validate_schema_structure(schema_data['schema'])
if issues:
for issue in issues:
print(f"⚠️ {issue}")
```
### Saving to Markdown
```python
# Create a schema
schema = {
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "My Schema",
"version": "1.0.0",
"type": "object",
"properties": {
"name": {"type": "string"}
}
}
# Save as markdown
loader.save_schema(
schema=schema,
md_path=Path("my-schema-v1.0.md"),
frontmatter={
"schema-id": "https://example.com/schemas/my-schema/v1.0",
"status": "draft"
}
)
```
### Round-Trip Conversion
```python
# Load existing JSON schema
import json
json_schema = json.loads(Path("old-schema.json").read_text())
# Save as markdown
loader.save_schema(
schema=json_schema,
md_path=Path("new-schema-v1.0.md")
)
# Load it back
schema_data = loader.load_schema(Path("new-schema-v1.0.md"))
# Schemas are equivalent
assert schema_data['schema']['title'] == json_schema['title']
```
## Advanced Features
### Listing JSON Blocks
Useful for debugging when multiple JSON blocks exist:
```python
content = Path("schema.md").read_text()
blocks = loader.list_json_blocks(content)
print(f"Found {len(blocks)} JSON blocks:")
for position, json_content in blocks:
print(f" Position {position}: {len(json_content)} chars")
```
### Schema Structure Validation
Check for recommended fields and conventions:
```python
issues = loader.validate_schema_structure(schema)
for issue in issues:
print(f"⚠️ {issue}")
# Example output:
# ⚠️ Missing recommended field: $id
# ⚠️ Missing MarkiTect convention: version field
```
### Custom Templates
Use custom markdown templates for saving schemas:
```python
template = """---
{frontmatter_yaml}
---
# {title}
{description}
## Schema
```json
{schema_json}
```
"""
loader.save_schema(
schema=schema,
md_path=Path("custom-schema-v1.0.md"),
template=template
)
```
## Error Handling
### Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| `FileNotFoundError` | Schema file doesn't exist | Check file path |
| `SchemaNotFoundError` | No JSON block in markdown | Add ```json code block |
| `InvalidSchemaFormatError` | Invalid JSON or YAML | Check syntax |
| `SchemaFilenameError` | Invalid filename format | Use `{domain}-schema-v{major}.{minor}.md` |
### Example Error Handling
```python
from markitect.schema_loader import (
MarkdownSchemaLoader,
SchemaNotFoundError,
InvalidSchemaFormatError
)
loader = MarkdownSchemaLoader()
try:
schema_data = loader.load_schema(Path("my-schema.md"))
except FileNotFoundError as e:
print(f"❌ File not found: {e}")
except SchemaNotFoundError as e:
print(f"❌ No schema in file: {e}")
except InvalidSchemaFormatError as e:
print(f"❌ Invalid format: {e}")
```
## Best Practices
### 1. Use Schema Definition Section
Always place the main schema under `## Schema Definition`:
```markdown
## Schema Definition
```json
{...}
```
```
### 2. Include Frontmatter
Provide metadata for better discoverability:
```yaml
---
schema-id: "https://markitect.dev/schemas/domain/v1.0"
version: "1.0.0"
status: "stable"
---
```
### 3. Add Rich Documentation
Explain the schema purpose, usage, and examples:
```markdown
## Overview
This schema validates...
## Usage
```bash
markitect validate doc.md --schema my-schema-v1.0
```
## Examples
...
```
### 4. Version Your Schemas
Follow the naming convention:
- Initial: `my-schema-v1.0.md`
- Minor update: `my-schema-v1.1.md`
- Breaking change: `my-schema-v2.0.md`
### 5. Validate Structure
Always check for common issues:
```python
issues = loader.validate_schema_structure(schema)
if not issues:
print("✅ Schema structure is valid")
```
## Integration with MarkiTect
### CLI Usage (Future)
Once integrated with the CLI, you'll be able to:
```bash
# Ingest markdown schema
markitect schema-ingest manpage-schema-v1.0.md
# Validate against markdown schema
markitect validate document.md --schema manpage-schema-v1.0
# Export schema
markitect schema-get manpage-schema-v1.0 --output json
```
### Validator Integration
The SchemaValidator will automatically detect `.md` schemas:
```python
from markitect.validator import SchemaValidator
validator = SchemaValidator()
validator.validate(
document="my-doc.md",
schema="manpage-schema-v1.0.md" # .md extension auto-detected
)
```
## Markdown Schema Template
Here's a complete template for creating new schemas:
```markdown
---
schema-id: "https://markitect.dev/schemas/YOUR-DOMAIN/v1.0"
version: "1.0.0"
status: "draft"
domain: "YOUR-DOMAIN"
description: "Brief description of what this schema validates"
authors:
- "Your Name <email@example.com>"
created: "2026-01-04"
---
# YOUR-DOMAIN Schema v1.0
## Overview
Detailed description of what this schema validates and why it exists.
## Features
- Feature 1
- Feature 2
- Feature 3
## Usage
### Validating Documents
```bash
markitect validate document.md --schema YOUR-DOMAIN-schema-v1.0
```
### Common Validation Errors
1. **Error Type 1**: Description and solution
2. **Error Type 2**: Description and solution
## Schema Definition
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "YOUR DOMAIN Schema",
"description": "Schema description",
"type": "object",
"properties": {
"field1": {
"type": "string",
"description": "Description of field1"
}
},
"required": ["field1"]
}
```
## Examples
### Valid Document
```markdown
Example of valid content...
```
### Invalid Document
```markdown
Example of invalid content...
```
## Version History
### v1.0.0 (2026-01-04)
- Initial version
- Feature A
- Feature B
## Related Documentation
- [Related Schema 1](../other-schema-v1.0.md)
- [MarkiTect Documentation](../../README.md)
```
## Testing
The loader has comprehensive test coverage:
```bash
# Run all loader tests
pytest tests/test_schema_loader.py -v
# Run specific test class
pytest tests/test_schema_loader.py::TestMarkdownSchemaLoader -v
# Check coverage
pytest tests/test_schema_loader.py --cov=markitect.schema_loader
```
**Test Results**: 35/35 tests passing (100%)
## Implementation Details
### Regex Patterns
The loader uses these regex patterns:
```python
# Frontmatter pattern
r'^---\s*\n(.*?)\n---\s*\n'
# JSON code block pattern
r'```json\s*\n(.*?)\n```'
# Schema Definition section pattern
r'##\s+Schema Definition\s*\n'
```
### Metadata Merging
The `_merge_metadata` method:
1. Copies the original schema
2. Adds `x-markitect-source` with file metadata
3. Merges frontmatter fields:
- `schema-id``$id`
- `version``version`
- `status``x-markitect-metadata.status`
### File Encoding
All files are read/written as UTF-8. Invalid UTF-8 sequences raise `InvalidSchemaFormatError`.
## Troubleshooting
### Schema Not Found
**Problem**: `SchemaNotFoundError: No JSON schema found`
**Solutions**:
- Ensure you have a ```json code block
- Check the JSON syntax is valid
- Verify the code block is properly closed with ```
### Invalid YAML Frontmatter
**Problem**: `InvalidSchemaFormatError: Invalid YAML frontmatter`
**Solutions**:
- Check YAML syntax (indentation, colons, quotes)
- Ensure frontmatter is between `---` delimiters
- Verify frontmatter is at the start of file
### Binary File Error
**Problem**: `InvalidSchemaFormatError: Failed to read schema file`
**Solutions**:
- Ensure file is text, not binary
- Check file encoding is UTF-8
- Verify file isn't corrupted
