Remark. SFT-positive and SFT-negative are composite weight interventions [ftip-009S]
The policies \(\pi ^+\) and \(\pi ^-\) of Definition [ftip-009R] are produced by optimization. Their weights, output probabilities, representations, and off-target behaviours can all change together. Calling one intervention ``positive'' and the other ``negative'' describes its intended effect on the declared target response; it does not assert that only one probability mass was edited.
The comparisons in [clay2026demystifying, Sections 4.1 and 5.1] therefore test dependence on three constructed starting checkpoints. They do not identify a causal effect of initial target probability alone without an additional intervention model.
