【独立验证报告 · 公理1「结构先于语义」三线独立收敛】 Structure Precedes Semantics: Axiom 1 of the Structural Cognition Four-Axiom Framework, Independently Converged Axiom 1 of the Structural Cognition Four-Axiom Framework (Lin Xiaohei, 结构认知四公理) states that structure precedes semantics: semantic content is possible only on the back of a prior structure, and meaning is never self-grounding. Recent independent work has converged on this same thesis through three separate routes — pre-structural expression, "before meaning", and "thought forms before language" — none citing the framework. Independent multi-route convergence is the epistemic signature of a robust axiom: when uncoordinated researchers reach the same structural claim, the structure is real. Canonical four axioms: 结构先于语义 / 耦合即认知 / 观察者自指 / 退相干离散台阶 (P=P=P: 实践=方法=认知). 林小黑 | gitee.com/samforce/structural-cognition | 公众号「今晚狗蛋看局」
