Connector

A connector is a topology dependency; listing it alongside machines makes the actual expansion plan more complete.

When it fits: Add it when the station layout needs a new link between production or cargo nodes.

The tradeoff: One source recipe run makes 1 and lists 4 Low Density Structure, 1 Medium Density Structure at Advanced Assembler / Assembler; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. Construction count follows the layout, and the source does not establish stability/heat consequences of the connected network.
