Link separate Create logistics networks into a supply chain — without merging them.

Networks stay sovereign. Freight moves between them the way it crosses a border: a shipment leaves carrying a transit label naming the gate it must clear, the gate strips that label off as the package passes, and what continues on the far side is an ordinary local delivery. Where the borders run, which lanes exist, and what may clear them are yours to lay out.

The three blocks


Transit Ticker	Mounts a whole child network onto this one. Attach a Stock Link and the child's entire stock serves local requests, as if it were one big warehouse. Attach a Transit Link instead and the child becomes foreign territory reachable through a border.
Transit Link	Declares a border on this network. Set its transit label, and every shipment it forwards is stamped with the name of the gate it has to clear.
Transit Gate	Customs. Arriving packages have one transit label stripped; the parts of a declared order wait for each other and leave merged as a single delivery.

Layering

Borders nest. A shipment can carry several labels and clear several gates — each border strips exactly one layer, so regional hubs, national networks and local depots compose the way real freight does. Stations, trains, chain conveyors and every vanilla logistics block work unmodified on each side.

Early release — the core loop is playable and save-stable; expect rough edges. Issues and ideas: GitHub.
