Model and Evidence Laboratory
Compare reconstructions event by event, ask what changes when an assumption is rejected, distinguish plotted coordinates from defensible historical ranges, and trace the formal propositions and rules behind major conclusions.
Side-by-side reconstruction
Chronology model comparison
Only chronology-sensitive core events are compared. A difference may concern visibility, date, title, confidence, coordinate role, or interpretation.
What changes if this is wrong?
Counterfactual assumption impact
The formal engine reruns the selected preset after changing one proposition. New contradictions, removed findings, and surviving conclusions remain separate.
Coordinate versus evidence
Historical uncertainty registry
Every core event is assigned a coordinate role. Exact external anchors, representative points, model coordinates, relative sequences, schematic periods, two-option windows, and undated material are not displayed as equivalent.
