If the conditions cannot be built away from below, perhaps they can be cancelled from above: take T, S, and Φ as given and negate them in turn, peeling structure off until nothing structured is left. The attempt defeats itself. Try to negate the conditions one at a time and the negating itself enacts them; press toward total absence and you reach only ∅.

*Dependency.* §[§1.3](<1.3 Change.md>)–1.4 only; fixed-point-asymmetry kin (Russell's foundation, Tarski's hierarchy, Cantor's diagonal). No S5, no conceivability premise, no theology. *Scope:* performative closure at worlds where negation is tokened, not a freestanding proof of □(T ∧ S ∧ Φ).
