- Replaced hardcoded keys in `activity_data_canon.py` with a dynamic retrieval method from the module registry, ensuring that `ACTIVITY_MODULE_REGISTRY_FIELD_KEYS` reflects the current configuration.
- Updated `activity_persistence_orchestrator.py` to utilize the new dynamic field retrieval function, enhancing consistency across the data layer.
- Modified `activity_session_metrics.py` to reference the dynamic field keys, improving maintainability and reducing redundancy in the codebase.
