Cherry's Pick

Preliminary

Confidence33% coverage / 3 of 7 signals

Score is partially shrunk toward a neutral 50 — read directionally until more source families land. Coverage is signal availability, not cup quality; missing sources are dropped, the remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 18% so a single thin signal can’t carry the score on its own.
