§3 · Resolution rules
If the President, any member of the Cabinet, any member of the Joint Chiefs of Staff, or any US federal agency definitively states that extraterrestrial life or technology exists before Jan 1, 2027, then the market resolves to Yes.
▸ Depth section using sovereign-store price series (764 bars · effective 350659 bars/year) — annualisation reflects native polling cadence, not upstream timeframes.
§4 · Honest position analytics
A binary-market analytics module framed in horizon time (days to resolution, not annualised). Estimators that need a model probability q as a first-class input (Kelly, KL divergence, Bayesian posterior, Mark-to-Market MC) only render when q is provided externally. Sweep an exploratory q at the interactive simulator →

External model required
The position-economics, Kelly, KL-divergence, Bayesian and Monte-Carlo surfaces require a model probability q as input — a number independent of the market price p.
The previous build defaulted q to a tape-momentum heuristic derived from p; that produces apparent edge that is structurally guaranteed to be small and is not a useful skill signal. The auto-derived path has been removed.
To explore these surfaces with a hypothetical q, open the interactive simulator and drag the MODEL P(YES) slider. To wire a real model, POST to the NOSTRADAMUS hook (TBD) or pass ?q=… on the simulator URL.
