Agent-drafted interpretation, pending human review

The strongest robust result in this collection is normalization. It produces the clearest positive alignment shift in a matched contrast while preserving the answer-quality gate. That result survives the larger extended dataset and remains the safest intervention to carry forward.

The more ambitious claims are more conditional. The specific twr2 contrast is inconclusive in the extended dataset, and the jsd0.5 contrast is only directionally positive. At the same time, the expanded run set reveals that beta0p1_norm_twr3_jsd0 is the strongest tested overall default. So the collection does not support a simple “TWR works” or “JSD works” binary claim; it supports a narrower statement that stronger normalized settings can help, and that the best TWR level in this study is not the one isolated by the original matched contrast.

The task-specific winner map also matters. No universal winner emerges, which means later sweeps should keep both a strong default and a task-conditional view rather than collapsing too early to one supposedly universal setting.
