Physical Spacetime Reconstruction
Can an expanding physical spacetime be generated from ACRF-type registration dynamics, rather than assumed?
ACRF-4 now has exact node-block nonautonomy and strict retained-edge densification, but its complete positive K-support graph does not derive sparse primitive-neighbor locality. The forward-generated boundary-growth and inter-host transfer structure required for physical spacetime remains unresolved.

Reconstruction of physical spacetime from registration dynamics
ACRF-4 now has exact node-block nonautonomy and strict retained-edge densification, but its complete positive K-support graph does not derive sparse primitive-neighbor locality. Deriving physical spacetime still requires a forward-generated boundary-growth and inter-host transfer structure whose complete dynamics remain unresolved.

Densification and Node-Block Nonautonomy in Canonical ACRF-4: An Exact Zero-Cut Destruction Theorem and Generated Cross-Cut Retained Coupling
An exact canonical ACRF-4 theorem package: every zero cross-cut is destroyed in one update, every retained edge becomes strictly positive, and the node update is not globally autonomous across a nontrivial node block.
