Update YAML schema documentation to reflect actual capabilities

[milliondreams]

Summary

Documentation: Update the YAML schema documentation and JSON schema to accurately reflect the test harness's actual capabilities rather than the incomplete YAML parsing exposure.

Background

The current YAML schema documentation was created based on YAML examples, but investigation revealed that many "documented" features either:

1. Are fully implemented but not exposed through YAML parsing (67% of features)
2. Need minor wiring (17% of features)
3. Actually need implementation (17% of features)

The schema should reflect the roadmap and actual capabilities. See analysis: cursor_workspace/implemented-vs-missing-analysis.md

Required Updates

1. Schema Documentation (cursor_workspace/yaml-test-spec-schema.md)

Mark Implementation Status:

• ✅ Implemented: Features ready for use after Expose implemented functionality through YAML parsing struct fields #347
• 🟡 Partial: Features available after Wire up partially implemented features to YAML configuration #348
• ❌ Missing: Features requiring Implement missing subscription testing and server management features #349

Update Feature Descriptions:

• Add implementation status indicators
• Reference GitHub issues for missing features
• Provide realistic timelines
• Include workaround suggestions

2. JSON Schema (cursor_workspace/yaml-test-spec.schema.json)

Reflect Current Reality:

• Mark unimplemented properties with warnings
• Add implementation status annotations
• Provide clear error messages for unsupported features
• Reference issue numbers for missing functionality

Schema Categories:

{
  "properties": {
    "field_validations": {
      "properties": {
        "contains": {
          "type": "string",
          "description": "✅ IMPLEMENTED: Available after #347",
          "x-implementation-status": "ready"
        },
        "subscription_expected": {
          "type": "boolean", 
          "description": "❌ NOT IMPLEMENTED: Requires #349",
          "x-implementation-status": "missing"
        }
      }
    }
  }
}

3. Updated Feature Matrix

Create comprehensive status table:

Feature	YAML Property	Status	Issue	ETA
String validation	contains	✅ Ready	#347	Immediate
Performance testing	max_execution_time_ms	✅ Ready	#347	Immediate
Script validation	script_config	🟡 Partial	#348	Medium
Subscription testing	subscription_expected	❌ Missing	#349	Later

4. Migration Guide

Add migration instructions:

• How to use current limited functionality
• What to expect after each issue is resolved
• Backward compatibility guarantees
• Feature deprecation timeline

Files to Update

Documentation Files:

• cursor_workspace/yaml-test-spec-schema.md - Add implementation status
• cursor_workspace/yaml-test-spec.schema.json - Mark unsupported features
• cursor_workspace/README.md - Update capability summary
• cursor_workspace/missing-features-analysis.md - Add resolution tracking

Schema Validation:

• cursor_workspace/validate-example.js - Add implementation warnings
• cursor_workspace/package.json - Update for new validation features

Implementation Tasks

Phase 1: Status Annotation

• Add implementation status to all schema properties
• Mark features with GitHub issue references
• Add realistic capability descriptions
• Update examples with working features only

Phase 2: JSON Schema Enhancement

• Add x-implementation-status annotations
• Provide helpful error messages for unimplemented features
• Add issue references in descriptions
• Create validation warnings for missing features

Phase 3: Documentation Restructure

• Create "Current Capabilities" section
• Add "Roadmap" section with issue timeline
• Update examples to use only working features
• Add migration guide for each capability level

Phase 4: Validation Enhancement

• Update validator to warn about unimplemented features
• Add "--strict" mode for current capabilities only
• Provide helpful suggestions for unsupported features
• Add "--future" mode for roadmap validation

Example Updates

Schema Property Documentation:

#### Field Validation Properties

##### `contains` (✅ Available after #347)
**Type**: string  
**Status**: Fully implemented, needs YAML exposure  
**Usage**: Validates that field content contains specified text  
**ETA**: Immediate (once #347 is resolved)

##### `subscription_expected` (❌ Not implemented - #349)
**Type**: boolean  
**Status**: Requires full implementation  
**Usage**: Will validate subscription lifecycle when implemented  
**ETA**: Future milestone (requires subscription infrastructure)

Validation Warning Example:

// In validate-example.js
if (yamlContent.includes('subscription_expected')) {
  console.warn('⚠️  WARNING: subscription_expected is not yet implemented');
  console.warn('    Track progress: https://github.com/rustic-ai/codeprism/issues/349');
  console.warn('    Current workaround: Test subscription manually');
}

Testing

Validation Testing:

• Run validator against existing YAML examples
• Verify warnings appear for unimplemented features
• Test that implemented features validate correctly
• Ensure helpful error messages for unsupported properties

Documentation Testing:

• Verify all examples use only supported features
• Test that migration guide is accurate
• Validate issue references are correct
• Ensure timeline information is realistic

Success Criteria

• Schema accurately reflects actual capabilities
• Clear implementation status for all features
• Helpful warnings for unsupported functionality
• Migration guide for each capability level
• Realistic timeline expectations
• GitHub issue integration for tracking

Impact

Prevents user confusion by providing accurate capability documentation. Enables users to understand what's available now vs. what's planned, and how to track progress on missing features.

Dependencies

• Should be updated as Expose implemented functionality through YAML parsing struct fields #347, Wire up partially implemented features to YAML configuration #348, Implement missing subscription testing and server management features #349 are completed
• Requires coordination with implementation timeline
• Should reflect actual merge status of capability issues

Status Update - Ready for Implementation ✅

Analysis Completed: The test harness has extensive implemented functionality that just needs documentation updates to reflect reality.

Current Situation

• 67% of features documented as "missing" are actually fully implemented in code
• Schema documentation was created from YAML examples, not actual capabilities
• Issues Expose implemented functionality through YAML parsing struct fields #347 & Wire up partially implemented features to YAML configuration #348 completed - most missing YAML parsing now resolved

Key Findings from Codebase Review

• Advanced field validation: ✅ Implemented in - just needs YAML exposure
• Performance monitoring: ✅ Full system in - comprehensive implementation
• Script validation: ✅ Multi-language support (Lua/JS/Python) - production ready

Implementation Status Matrix

Feature Category	Code Status	YAML Status	Action Needed
Field validation	✅ Complete	✅ Exposed (#347)	Document as available
Performance tests	✅ Complete	✅ Exposed (#347)	Document as available
Script validation	✅ Complete	✅ Exposed (#348)	Document as available
Subscription testing	❌ Missing	❌ Missing	Mark as future work

Next Steps

1. Update schema documentation to reflect actual implementation status
2. Mark features with GitHub issue references for tracking
3. Add implementation status indicators (✅/🟡/❌)
4. Create migration guide for different capability levels

Estimated Effort: 2-3 hours of documentation updates
No code changes required - this is purely documentation synchronization.

Ready to proceed - no blockers identified.
