LassaAI · prospective scientific record

Predictions first. Outcomes later. Nothing rewritten.

This page publishes the auditable receipt stream for the frozen 2026–27 national Lassa fever forecasting study. A forecast is committed before its four-week outcome window resolves. When the outcome becomes available, it is attached as a separate hash-chained record.

Study status
Scientific boundary. The frozen protocol defines the endpoint, threshold, model, features, training rule, comparators, calibration, uncertainty procedure and success/neutral/failure rules. The freeze establishes anteriority and integrity; it does not establish forecasting skill or clinical/public-health utility.

Prospective receipt stream

Each receipt preserves forecast time → information set → model probability → baselines → hashes → outcome horizon. When resolved, the separate outcome record adds observed burden and score contributions without altering the forecast bytes.
