Notes on the experimental data (data/runs/*.json):

  * Each run record includes the IBM Quantum backend name, qiskit version,
    timestamp (JST), shot count, and raw measurement counts.

  * IBM Quantum API tokens, account identifiers, and any
    personally-identifiable session metadata are intentionally REDACTED
    from all committed JSON files. Only `session_id` and `job_id` strings
    (which are public IBM Quantum job references and contain no
    credentials) are retained for reproducibility.

  * If you reproduce these experiments on your own IBM Quantum account,
    your results will differ due to hardware noise, calibration drift, and
    backend availability. This is expected and documented in each
    experiment's README.

  * NEGATIVE RESULTS: Some runs under data/runs/ — particularly anything
    referenced from src/quantum_flex/experiments/_wip/ — are deliberately
    preserved failures. They are part of the dataset's scientific value,
    not bugs to fix.
