Scheduled locality, regular transport, and resources

The theorem is an ancestry bound, not equality with the physical causal past IB,VIIE,En08A. Postselection is not a deterministic intervention. Entangled inputs do not invalidate the theorem, but separate marginals do not determine a joint ancestor–reference input.

Choose a straight developed spatial segment of length $\ell >0$ in the inherited regular convex tube. After readout, lookup, and a positive processing buffer, depart at $t_{\mathrm{d}}$. For $n\ge 1$, place stations

Each station has a $p$-qubit register $A_j$. Initialize $A_1,\dots ,A_n$ in independent blanks $\omega$. At hop $j$, SWAP $A_{j-1}$ and $A_j$ across developed duration $\ell /n$.

The tick-boundary SWAP is a declared finite permission, not a derived microscopic gravitational Hamiltonian. Its cross-port dependencies are null; same-station dependencies are timelike. Classical report wires have their own route certificates.
