Preliminary

Confidence2 of 7 signals on file

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. This coffee has 30% of the signal universe on file. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 25% so one thin signal cannot carry the score on its own.

The math on file: renormalized base 30.6 shrunk to 35.5 = 35.
