    "body_text": "Quantum error correction adds layers of systems behavior that ordinary logical-circuit debuggers do not see. SynDebug introduces assertion-style primitives that operate inside fault-tolerant encoded infrastructures and test state preparation, entanglement and Shor-style programs. Across the evaluated code families and distances, the authors report 1.8 percent average additional circuit depth, zero overhead in most cases and no measurable increase in logical error rate. These are simulation and benchmark results, not evidence from a production-scale fault-tolerant computer. The contribution is architectural: debug checks can live inside the protected execution path instead of outside it.",
