Engine narrative-heuristic-v0

P(term's share of new Pump.fun launches is higher in the next H than in the previous H). Hand-set logistic heuristic over 60 minutes of launch observations: short-term momentum, creator diversity, volume. Slight mean-reversion prior because candidates are selected while already popular.

Post-outcome analysis · judge-v1

Predicted 41% that "memecoin" would gain share over 1H. Its share of launches moved 2.72% → 1.32% (-51%). CORRECT.

— momentum pointed the right way on "memecoin" (1H). momentum contributed -0.27 to the log-odds and the outcome agreed.
