A nonempty regular transport route

Choose a straight developed spatial segment of length $\ell >0$ in the inherited regular convex tube, with a time reserve after readout, lookup, and a positive processing buffer. At $n+1$ target-adapted stations put $p$-qubit payload registers $A_0,\dots ,A_n$. Registers $A_1,\dots ,A_n$ start in independent blank states $\omega$. At hop $j$, SWAP $A_{j-1}$ with $A_j$ across developed duration $\ell /n$.

These are declared tick-boundary finite permissions, not instantaneous equal-time interactions or a derived gravitational Hamiltonian.
