Evidence levels describe source coverage, not the probability that a report is true. Price moves and their timing cannot establish a cause; minute samples show an observed interval and alert thresholds are heuristics. Explanations are model-assisted, with citations and figures checked. Source titles stay in their original language; full articles are not republished.
