Introduction, target, and scope

The exact causal-cone theorem of En05-A separates three objects: scheduled ancestry, its metric envelope, and actual operational influence CheungEn05A. Its continuum conclusions require additional realization hypotheses. In particular, an upper envelope does not establish boundary transport, and separately convergent experiments need not have locally matched realizations.

The immediate construction problem is therefore:

Construct a family whose Euclidean upper cone and attainable transport cone converge to the same cone, while preserving complete finite experiments and local interventions.

A fixed finite periodic transport model cannot solve the isotropy problem by uniform rescaling alone: its asymptotic velocity set is a polytope Fritz. The cardinal instance is the diamond discussed in En03-A, VII-E, VII-J, and En05-A CheungEn03,CheungVIIE,CheungVIIJ,CheungEn05A. Here the directional set, the quotient size, and the microscopic interfaces are allowed to grow.

scheduling mechanism. A junction is not permitted to participate in several blocks at one tick. Instead, every incident lane has its own endpoint site. All endpoint sites belonging to a junction, together with its memory site, form one small-diameter junction block. The interiors of different lanes are disjoint. Consequently all directions can be served in parallel during a transport frame.

This construction uses the permission in En05-A to admit arbitrary finite complete block channels without a uniform bound on block cardinality or within-block gate depth. It would not establish an existence theorem with those additional bounds.
