Bring scheme versions, review notes, and the approved baseline into one decision package that identifies changed regions, records approval status, and preserves a usable rollback point.

The actual workflow — connected nodes you can run to preview each step.
Professional capabilities powered by AI.

Compare what actually changed instead of relying on filenames, memory, or presentation order.

Preserve the accepted parts of a version while identifying changes that still require correction.

Return to a documented baseline without losing the reasoning behind the earlier decision.
A rollback package needs a specific version reference, not a description such as “the previous image.” Record the identifier, date, decision state, and associated review notes.
Separate visible differences from approved decisions. A change may exist without having been accepted, and an approval may apply to only part of a version.
Preserve dependencies when rolling back. Related views, material references, branch settings, and downstream outputs may also need to return to the same design state.
Compare changes, record approval clearly, and preserve the baseline needed to recover the accepted direction.
