The inherited regular route

Choose a straight developed spatial segment of length $\ell >0$ inside the inherited regular convex tube. After readout, local lookup, and a positive processing buffer, depart at developed time $t_{\mathrm{d}}$. All selected events remain in the available laboratory time reserve.

Install $n+1$ stations

with payload factors $A_j\cong {\mathbb{C}}^{2^p}$. Initialize $A_1,\dots ,A_n$ in independent blank states $\omega$. At hop $j$, exchange $A_{j-1}$ and $A_j$, using developed tick duration $\ell /n$.

A two-register SWAP on these declared tick-boundary ports is an explicit inherited permission. Cross-port dependencies are null and same-station dependencies are timelike. A microscopic interaction Hamiltonian is not inferred. Classical report wires have their own causal certificates.
