Rank the Relative Importance of YouRA Components

Determine the relative importance of the MCP tool layer, Stateful Reflection, Verification State Architecture, and Independent Controller in YouRA by establishing whether their contributions can be reliably ranked according to the performance drop caused by removing each component.

Background

The paper evaluates four YouRA components through single-component ablations on a matched set of 30 backbone–task cells spanning three language-model backbones and ten MLR-Bench tasks. Removing each component significantly lowers the Overall score, demonstrating that all four components contribute to system performance.

However, pairwise statistical comparisons of the performance drops caused by removing MCP, Stateful Reflection, the Verification State Architecture, and the Independent Controller yield no reliable differences after Holm correction. The authors therefore leave unresolved whether any component is more important than the others, or whether their contributions should be considered statistically indistinguishable under the current evaluation design.

References

Every pairwise contrast has Holm-adjusted permutation $p{=}1.000$, so this sample cannot support a reliable ranking of components by drop size. The two analyses show that each component contributes while leaving their relative importance open.
