Morphology
The meaning 'a demonstration using logical reasoning' is directly and transparently derived from combining 'logical' (relating to logic/reasoning) with 'proof' (a demonstration). This compositional adjective + noun pattern is regular and cross-linguistically common, so a B1 learner who knows both words will readily infer the MWE meaning.
Etymology
Logical proof comes from the simple idea of proving something by clear steps. Think of proof as a test and logical as careful reason, like a staircase where each step follows the last, so a logical proof 'shows' that a statement is 'true'.
