Variant Aggregates

Variant	Mean score	Part MAE	Joint F1	Success	OT diagnostics
Official PAct Released PAct cache, no OT wrapper.	27.91	12.40	0.05	1.00	-
Phase2 mask dropout Mask labels stay as a soft inference prior; training randomly dropped the prior.	27.67	12.40	0.03	1.00	-
Phase2 RGB edge + dropout Mask-prior dropout training plus RGB edge-regularized OT at inference.	27.68	12.40	0.03	1.00	-
Phase2 first-third edge + dropout Wider first-third OT injection trained with stochastic mask-prior dropout.	27.06	12.40	0.01	1.00	-
