The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We present a controlled multidimensional pairwise evaluation framework for multilingual TTS that combines linguistic control with perceptually grounded annotation.

C2weakest assumption

That the 120K pairwise comparisons from 1900 native raters, despite acknowledged high variance in speech perception, yield reliable signals for Bradley-Terry leaderboard construction and SHAP interpretation after linguistic controls.

C3one line summary

A controlled pairwise evaluation framework for multilingual TTS in 10 Indic languages produces a preference leaderboard using Bradley-Terry modeling and SHAP analysis on 120K+ comparisons.
