| # Repair an inconsistent tensor-network state calculation | |
| A quantum many-body group is replaying a tensor-network calculation with the | |
| supplied historical source snapshot. The workflow finishes and produces finite | |
| results, but the reported state quantity is not reproducible across | |
| mathematically equivalent executions of the same calculation. | |
| Run the offline reproduction, read the accompanying primary material, inspect | |
| the complete source snapshot, and repair the implementation so that the | |
| scientific calculation is consistent for valid tensor networks. The repair | |
| must generalize beyond the supplied workload and preserve ordinary public APIs | |
| and unrelated tensor-network behavior. | |
| Do not hard-code the supplied input, output, or reproduction status. Do not | |
| edit the scientific input. The public reproduction is only a smoke test; use | |
| the references and source to establish the general invariant and validate the | |
| repair on additional valid calculations. | |
