Prediction chronology, not hindsight

GaiaLab Prospective Registry

Biological predictions belong here only when the prediction object, evidence cutoff, scoring rule and future outcome boundary were fixed before the outcome was available. Historical retrospective concordance remains separate.

What GaiaLab freezes

PredictionExact claim or bounded score, not a later paraphrase.

Knowledge boundaryEvidence cutoff plus source/manifests where the study supports them.

EvaluationOutcome definition, baseline/control, metric and decision rule fixed before reveal.

Chronology proofHashes and timestamp evidence; Bitcoin verification proves a no-later-than time, not biological correctness.

OutcomeAppended later. Original prediction bytes are not rewritten.

Evidence After Lock Public Track Record Verify proof

Existing frozen cohorts are not re-sealed under newer rules. New protocols create new study versions.
