Methodology versions

Each match is scored under a specific methodology version. Bumping the version means a meaningful change in how scores are computed : a re-balanced axis weight, a different concordance formula, a Glicko config change, an axis added or removed. Silent fixes that don't move scores stay un-versioned.

1. v1.0

   2026-05-10 current
   • · Initial public methodology. 9 quality axes in 3 families (Foundation, Form, Context).
   • · Five verdict labels per axis (A_WINS_CLEARLY, A_WINS_SLIGHTLY, TIE, A_LOSES_SLIGHTLY, A_LOSES_CLEARLY).
   • · Concordance composite : 33% embedding similarity + 33% mean axis relevance + 33% subject-similarity label.
   • · Glicko-2 update per axis, weighted by concordance. Single ContentRank derived from the nine per-axis ratings.
   • · Anti-hallucination check : each cited passage verified against the source text.
   • · Position-bias mitigation : URL matches run twice with A and B swapped.
