Guide / Every rule

The diagram means something different

The check drawing/semantic-drift, in the group Drawing.

Error

Why it matters

Laying out must move things and change nothing else; an element with a different parent, source or target is a different process.

How to fix it

Undo the change and report it: no layout should ever do this.

Where you see it

The Problems tab lists it under Problems, and outlines the element on the canvas. In a terminal, penstock check --only drawing reports it as SEMANTIC-DRIFT. Auto layout often fixes it for the whole diagram at once.
