Current operating documentation and repeated customer results separating realized gains, classical computation and any quantum execution.
What evidence would help
A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Does the result count sampling, mitigation and classical processing costs?
What would resolve it?
An editorial review must explain which part of this question the evidence resolves. A roadmap or an announcement alone does not close it.
No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.
