| positive_conditioningopt | CONDITIONING | Optional external positive conditioning. When connected, it overrides Generation Core's internal positive-text encoding. Useful for image-edit encoders that attach reference-image conditioning. | |
| negative_conditioningopt | CONDITIONING | Optional external negative conditioning. When unconnected, Generation Core keeps its existing empty-negative behavior. |
