Joint-240 SBS Disagreement and One-Step Counterfactual Action Outcomes

Historical exploratory synthetic-simulator dataset from 240 independently seeded Joint-240 scenarios. The release contains 8,886 retained SBS-disagreement state-context records and 21,854 alternative-action terminal outcomes from 236 represented scenarios. Each alternative action is followed by fixed SBS continuation. The release preserves positive, negative, and null effects (2,573 / 3,624 / 15,657 ANWG classes at the original 1e-12 threshold), excludes 98 unresolved historical-overlap keys, and excludes already-public reference utilities and learnability aggregates.

This dataset is not the Performance Evaluation manuscript's production-derived confirmatory evidence (PEVA-D-26-00474). It is historical exploratory simulator evidence used to motivate a fixed SBS reference.
