What survives, and where it goes. Uploading is the hardest case the framework can be put to — which is exactly why it is here. This movement is a stress test, not a prospectus.
Navigation: ‹ Every Perspective Is Non-Redundant · Bandwidth Separates Inheritance From Continuation ›
What would it take for a person to continue somewhere else?
Movement III ended with a limit: inheritance is powerful, but narrow channels cannot carry a whole memory layer. A book can preserve a voice. A child can inherit a recipe for a learner. A culture can transmit methods, stories, and warnings. But none of those is automatically personal continuation.
Movement IV asks what would be different if the channel were wide enough, sustained enough, and integrated enough to carry the memory layer itself.
This is why uploading belongs here. It is not introduced as a forecast or a business plan. It is the hardest test case for the account built so far. If the framework can say clearly what would count as continuation, what would count only as inheritance, and what copy routes actually cost, then it has earned its keep.
Continuation requires enough bandwidth and integration to carry the memory layer while preserving the boundary; the strongest routes keep one boundary maintained, while copy routes remain possible but costly because what dies in them is the unsaved delta.
That is the conceptual claim. It does not say current technology can do this. It does not say when it could. It does not promise survival.
It only says what would have to be true.
