Scaffolding Beats Reasoning
A preprint from Salesforce and UIUC shows that a strong model can construct inference-time "harnesses" — structural scaffolds applied to a weaker model at test time — that nearly double Theory-of-Mind accuracy from 0.49 to 0.91 without any fine-tuning. The mechanism isn't more reasoning; it's converting unstable reasoning into deterministic code, routing, and format enforcement.
