• Entrypoint configuration (Python, v1_0_0/node.py)
• Capabilities list (derived from PRD + node type)
• Protocols supported (node-type specific)
• Version Management via x_extensions:

• Logging configuration (level, format, audit events)
• Tags (domain, node type, keywords from PRD)

4. version_manifest_template.yaml (75 lines)

Version-specific implementation details (Tier 3):

• Version identity (semver, status, release date, security profile)
• Implementation files tracking:
  • contract_file, main_implementation, module_init
  • model_files (input, output, config, contract model)
  • enum_files
  • contract_files
• Validation requirements (contract compliance, testing requirements)
• Deployment configuration (execution constraints, runtime requirements)
• Security context (input validation, output sanitization)
• API surface (primary entry point, model contracts)
• Quality metrics (code coverage, cyclomatic complexity, maintainability index, technical debt ratio)

🧪 Test Fixes

OnexError Assertion Fixes

Fixed test assertions to access error.details directly instead of error.model.context:

• test_validate_enum_code_missing_imports - PASSING ✅
• test_validate_enum_code_missing_methods - PASSING ✅

ONEX Compliance Fixes

• Removed spurious ONEX naming convention warning from enum_generator.py
• Updated mixin test to reflect ONEX-compliant mixin initialization (mixins handle their own __init__)

⚠️ Deprecation Warning Fixes

Replaced datetime.utcnow() with datetime.now(timezone.utc) across 4 files:

• omninode_template_engine.py - 3 occurrences (lines 1028, 1103, 1281)
• codegen_events.py - 1 occurrence (line 18)

Result: 237 warnings → 24 warnings (90% reduction)

Remaining 24 warnings are in test fixtures (datetime.utcnow() in SimplePRDAnalysisResult creation) - not Phase 6 code.

📦 Generated Artifacts Per Node

Each generated node now includes:

Existing Files:

1. Main node file (v1_0_0/node.py)
2. Input model (v1_0_0/models/model_{name}_input.py)
3. Output model (v1_0_0/models/model_{name}_output.py)
4. Config model (v1_0_0/models/model_{name}_config.py)
5. Operation enum (v1_0_0/enums/enum_{name}_operation_type.py)
6. All __init__.py files

NEW Files (Phase 6):
7. Contract model (v1_0_0/models/model_{name}_{type}_contract.py) ← Python Pydantic
8. Contract YAML (v1_0_0/contract.yaml) ← ONEX-compliant YAML (enhanced)
9. Node manifest (node.manifest.yaml) ← Tool-level manifest
10. Version manifest (v1_0_0/version.manifest.yaml) ← Version-specific manifest

✅ ONEX Compliance

All generated artifacts follow ONEX architectural patterns from omnibase_core PR #58:

• ✅ Strong typing (zero Any types)
• ✅ Contract-driven development
• ✅ Protocol-based interfaces
• ✅ Proper naming conventions
• ✅ Subcontract composition (5 standard subcontracts)
• ✅ Interface version locking (INTERFACE_VERSION)
• ✅ Validation enforcement
• ✅ Quality metrics tracking

• ✅ Contract YAML structure matches canary_compute examples
• ✅ Node manifest follows tool manifest pattern
• ✅ Version manifest matches tier 3 specification
• ✅ Contract models follow ModelRetrySubcontract pattern
• ✅ Subcontract integration matches established patterns
• ✅ Version management via x_extensions

🎯 Next Steps (Future Enhancements)

1. Add validation for generated contracts against JSON schemas
2. Implement contract model validators (similar to ModelRetrySubcontract)
3. Add support for custom subcontracts based on PRD analysis
4. Generate contract test suites automatically
5. Integrate with omnibase_spi validators when available

Poem

In burrows of docs I hop with glee,
New rules sprout tall like meadowry.
Hooks hum, selectors swiftly choose,
Debug stars map the trails we use.
Indices bloom, configs align—
I thump: “Ship shape, on the vine!” 🐇✨
