The two empty zones and\nthe region between them tile the analytic scope, which yields\nthe reported areas as one identity rather than as separate\ndefinitions: a weakest-component effect, a normalised geometric\nmean of the two components, the share of the scope the claims\njointly rule out, and the data zone they still admit. The\nconjunction is decided by an intersection-union combination of\nthe two directional permutation tests, optionally driven by a\nsingle shared permutation sequence so that a statistic of both\ncomponents can also be tested. These are random-pairing screens\nrather than direct tests of a causal necessary-and-sufficient\nrelation, no magnitude benchmarks are asserted for the joint\nindices, and a dual-threshold table separates outcome levels\nthat are out of reach, admitted, or guaranteed. An ordinary\nleast-squares line can be drawn alongside the two frontiers as\na central-tendency reference; it is an average-effect summary\nand is never treated as a component of either claim.",
