IEditorCommand

Remarks

Undo is a command stack, not a snapshot diff. Snapshots are simpler and they cannot represent "renamed this asset, which updated four hundred references" as one step, because the four hundred documents were never opened. A command can: it is the operation, so it knows what it touched.

Everything the editor edits goes through this one vocabulary, which is what makes undo/redo, dirty tracking and the remote inspector work uniformly rather than once per feature. A drawer that mutates a value behind the stack's back is the bug this interface exists to make obvious.
