Remark: Crossings, overlaps, and dimension one

Coincident geometric wires can be transported as distinct private residue lanes, or as a bundled typed register when their skeletons allow it. Crossing geometric segments need no special interaction because their site sets are disjoint.

At an actual payload junction, gathering and dispersal are exactly Lemma lem:junction. In particular, the proof does not rely on a false positive equal-time separation between crossing curves. It applies unchanged in $D=1$.
