Compute a 0-100 weighted momentum score for an emerging target or modality from conference share-of-voice (AACR/ASCO/ASH/ESMO abstract share, JPM January agenda), financing and NewCo-formation flows, and Altmetric as a calibrated high-noise tripwire. Treats reflexivity as structural and pairs the score with a contrarian froth-vs-merit overlay plus an orthogonal Consensus evidence-maturity gate. Activate when sizing where scientific attention and capital are flowing, whether a theme is pre- or post-consensus, and whether momentum is durable merit or reflexive hype.
