This paper develops a structural account of collapse, arguing that collapse is not a failure of individuals, ideology, or competence but a predictable consequence of degraded relational architecture. The paper identifies three structural invariants—orientation, signal integrity, and responsibility alignment—and shows how their breakdown produces drift, fragmentation, and loss of corrective capacity. Collapse is presented as a geometric phenomenon: a system loses the architecture required to sustain coherence. The paper concludes by outlining the principles of structural correction and the conditions under which collapse can be reversed.
