Arm Short I

The arm category and reach help distinguish machine-adjacent transfers from long-distance movement; count every handoff in a layout.

When it fits: Use it for nearby inputs/outputs and consider a longer arm only when geometry requires it.

The tradeoff: One source recipe run makes 1 and lists 2 Gear, 2 Iron Plate at Assembler I / Assembler II / Assembler III / Assembler IV / Assembler V; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. A short arm cannot solve a distance or belt-capacity problem; construction totals grow with each machine connection.
