Topology Reads Circuit Logic: IRDME Identifies Carry Propagation Hubs from Wiring Alone
A pre-registered experiment on a 4-bit ripple carry adder: IRDME, given only the physical wiring topology and exhaustive simulation state correlations, correctly recovers the carry propagation chain as the structural hub -- without any symbolic circuit description. Pearson r = 0.5117 (p = 0.004, large effect). The carry bits are persistent betweenness hubs across both layers (cross-layer betweenness r = 0.7714).
