01
Explain the kind of agreement intended
Two diagrams can agree in position, shape, labels or scale, and those are different conditions. The name’s suggestion of coordination becomes useful when a page identifies which agreement matters. A translation exercise concerns position under a fixed shift; it does not correct a rotated or stretched drawing. A future product description could list those capabilities separately. Showing a small counterexample alongside the supported case helps readers understand the boundary through the diagram itself, without turning the introduction into an unsupported promise of universal alignment.
02
Keep source coordinates available
Once a transformed drawing looks convenient, it can be tempting to retain only the new coordinates. Keeping the source values and the applied transformation makes the result easier to inspect and reverse. A TopoSyn notebook could display these in adjoining columns. For each point, the reader sees the original pair, the shift and the resulting pair. This structure also helps distinguish an edit to the source from a change in the transformation, which would otherwise appear as unexplained movement in the final picture.
03
Use correspondence labels consistently
Point labels identify which source and target positions are intended to represent the same location. A mistaken correspondence can produce a mathematically valid transformation that answers the wrong question. The example therefore retains P, Q and R across both lists. A real workflow would need a way to review those pairings before calculation. The name can support a careful coordination identity through such small interface choices: stable labels, visible pairings and a record of which correspondences were used to propose or check the mapping.
