 "method_note": "Each scenario run perturbs only the model's visible 16-event context window at the anchor (removing matching events and letting earlier real corpus events fill the window, or duplicating them in place of the oldest other events, with the window-internal time gaps recomputed) and re-runs the actual trained StructuredStateJEPA checkpoint forward pass to get a new context latent. That latent is mapped to 25-year label shares by the run's frozen ridge readout over the anchor's trailing-25-event persistence — the same projection pipeline behind the public forecast cards, verified here by reproducing the run's sealed frontier forecast before any scenario runs. The 25-year horizon matches the site's forecast cards (the model's native prediction horizon is 8 events, not years). These are descriptive sensitivity probes of the model, not alternate-history claims: no alternate ground truth exists.",
