Structural Alternatives to Decoupled Collapse: Mutual Coherence as a Condition of Joint Persistence

Status. Hypothetical framework. This note does not predict extinction, does not issue moral commands, and does not claim that current AI systems are already on an irreversible path.

The argument remains conditional and diagnostic.
