A Targeted Causal-Break Test for Engineered History Dependence on a Superconducting Quantum Processor

This archive contains the Version 1 public release of the targeted causal-break testing protocol together with the manuscript, supplementary material, registered experimental protocols, QASM circuits, analysis procedures, and documentation associated with the study. The work demonstrates a low-setting experimental methodology for testing engineered history dependence on superconducting quantum hardware while explicitly preserving preregistration records, failed controls, confirmatory replications, calibration experiments, and protocol revisions.
