Review groups changes by element and shows the requested value, original value, scope, source evidence, mapping confidence, and affected instance count. You can edit, include, reject, or permanently delete an unapplied change. Deleting removes it from the local batch and restores its recorded original value on the canvas.
A preview is not a source edit. Unresolved mappings must be resolved before a change can be included in an Apply run. Keep the included changes scoped to the direction you actually want to implement.
Compare temporarily returns to the canvas for before and after toggling, continuous scrubbing, side-by-side inspection, or element isolation. Returning to Review preserves approvals and edited values.
