Name-mover head. Isolated in the indirect-object-identification (IOI) circuit — one of the most completely reverse-engineered circuits in a real model. Given “When Mary and John… John gave a drink to ___”, the name-mover attends from the final position to the name that was not repeated as subject (Mary) and moves it into the output slot. Amber tier: the move-the-attended-name mechanism is exact; the prompt is the canonical IOI construction.
