Start with the PowerBI Dashboard and compare the fortunes, json, and single_query benchmark runs listed in the issue, including their reported deviations and dependency changes. Reproduce the affected scenarios, identify the source of the regression, and consider the work done when the benchmark results no longer show the reported degradation.
