Evidence-of-quality score, not a cup score. Methodology

Preliminary

Confidence33% coverage / 3 of 7 signals

Score is partially shrunk toward a neutral 50 — read directionally until more source families land.

How confidence affects the score

Coverage measures signal availability, not cup quality. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 18% so one thin signal cannot carry the score on its own.
