I think the JS SDK has the same issue. Could you follow up with that?

Description
Eval stores base_experiment_id correctly on the experiment but the final summary does not pass it as the explicit comparison ID. As a result, summary comparison can fall back to project/default baseline resolution and show wrong diffs.
Fix
Pass
evaluator.base_experiment_idintoexperiment.summarize(comparison_experiment_id=...), so score and metric diffs are computed against the explicit experiment baseline.Also resolve the explicit comparison experiment name so the returned summary displays the correct “compared to” name. Previously,
comparison_experiment_idwasNone, sosummarize()calledPOST /api/base_experiment/get_id; that resolver can apply UI/default-baseline behavior, including letting a project default baseline override the experiment’s explicitbase_exp_id.
