Preprint reports certified bounds on record-conditioned third-order interference using quantum methods, highlighting potential for systematic diagnostics.
This preprint reports DAGI-QWH-I3-001, a sealed, power-calibrated superconducting-quantum-hardware campaign measuring record-conditioned third-order Sorkin interference surfaces. The work tests whether order-2 closure of the quantum-measure interference tower survives observer refinement by conditioning on partial-strength which-path records, eraser bases, and record timing. It reports a certified record-conditioned bound, two mechanism-classified trap classes, and a structural-zero instrument methodology for diagnosing systematics. This record includes the manuscript v1.5 and the replication and auditing package v1.0.
