 "input_matching":"The same four-channel candidate events per seed are mapped to mirror targets for A and B. Quiet uses the same candidate events with gate0. All8 potential HS/H2 inputs use refractory0ms per the original author's stimulation convention; no descending output is directly stimulated.",
 "criterion":"For every new seed, DNp15 left>right under A, right>left under B; quiet outputs0. Preserve the same anatomical readout signs. Report DNa02 secondarily with no output selection. No gain fitting.",
 "interpretation":"A diagnostic only. A pass would show that this direct upstream drive can access both channels, without establishing the unique reason the visual bridge failed. A failure would not distinguish anatomical asymmetry, absent electrical connections, model dynamics or annotation assumptions. No visual perception, autonomous behavior, plasticity or body control is tested here."
