Summary

A feedback controller adjusted activation steering while masked tokens remained revisable.

On ambiguous bias questions, closed-loop steering raised one model's targeted-group preference from 1.8 to 16.7 percentage points and increased stigmatizing answers on another dataset from 17.6% to 58.1%. The attack assumes internal activation access, but it shows that a diffusion model's repeated denoising steps create an intervention surface absent from one-shot token commitment.

Why it matters

A feedback controller adjusted activation steering while masked tokens remained revisable.
