I focus on the z = 1 case, meaning that exactly one circuit is active on each forward pass. This restriction simplifies the setting substantially and allows a construction with zero error, with T = D 2 d 2 , L + 2 layers, and width D ( 1 + 1 d + ⌈ log 2 D d ⌉ D ) . While the construction does not directly
