Paper 2 in the Prioris research series. Evaluates PMI/NPMI, G-test, and Granger causality for observation-level edge detection (INVOLVES_ACTOR, PATTERN_OF). Derives minimum corpus size requirements and threshold selection criteria across four professional domains. Part of the Evidence-Graded Knowledge Graphs research programme (Paper 0: 10.5281/zenodo.19024611).
