KOKU Anomalous-Force Question Cascade: A Factorial Digital Laboratory for Momentum-Channel Falsification

This technical note turns a speculative non-reaction-propulsion question into a sequence of falsifiable questions. Seven candidate theory classes are screened by momentum-channel accounting. A randomized 256-block factorial design separates a declared device-fixed anomaly signature from magnetic, wiring, thermal, drift and dummy-load signatures. Six injected amplitudes are tested with 600 Monte Carlo trials each. Within the declared synthetic model, the combined false-positive rate is 0.5% and detection probability at an injected 5 nN is 90.5%. All data are synthetic. The 5 nN value is an injected simulation parameter, not an instrument sensitivity or measured output. No physical force or thrust was detected, and non-reaction propulsion is not claimed.
