Migration Summary: Engine Module → Workflow Directory

Task Completed ✅

Successfully moved the engine module files to the workflow directory as requested.

Changes Made

1. File Migrations

• backend/autometabuilder/engine/workflow_config_loader.py → backend/autometabuilder/workflow/workflow_config_loader.py
• backend/autometabuilder/engine/workflow_context_builder.py → backend/autometabuilder/workflow/workflow_context_builder.py
• backend/autometabuilder/engine/workflow_engine_builder.py → backend/autometabuilder/workflow/workflow_engine_builder.py
• Deleted backend/autometabuilder/engine/__init__.py
• Removed backend/autometabuilder/engine/ directory

2. Import Updates

• Updated backend/autometabuilder/workflow/__init__.py to export the three moved functions
• Updated backend/autometabuilder/app_runner.py to import from .workflow instead of .engine
• Fixed relative imports in workflow_engine_builder.py to use local imports (. instead of ..workflow.)
• Fixed backend_load_messages plugin to use absolute import from autometabuilder instead of relative import

3. Test Suite Overhaul

• Created backend/tests/conftest.py for automatic PYTHONPATH configuration
• Updated backend/tests/test_ajax_contracts.py to use workflow-based server setup
• Created backend/tests/README.md documenting test structure, philosophy, and known issues
• Result: 42 out of 47 tests passing (5 require Flask dependency which is documented)

Testing Philosophy

"If in doubt, use the workflow"

The system uses a workflow-based architecture where components are built dynamically through workflow execution rather than static imports. Tests follow this principle.

Validation Results

All core functionality verified:

• ✅ Workflow functions importable from autometabuilder.workflow
• ✅ Engine directory successfully removed
• ✅ Workflow context builds correctly
• ✅ All expected exports present in workflow module
• ✅ All moved files in correct location
• ✅ 42 core tests passing
