    How to read this

    Activation counts published dossiers, not verified damage. A base rate is k/n comparable historical episodes, with a 95% Wilson interval; fewer than five cases means no percentage. Research examples outside a fixed comparison set are not counted. We never multiply link probabilities. Without whole-chain precedents the chain remains speculative. An indicator value is not a forecast. Forecasts require a dated indicator, threshold and deadline; resolved forecasts remain visible and receive a Brier score (0 is best). We forecast consequences, never attack targets or timing.
