The Draft step stays reachable after you generate
If you skipped workspace scanning and then generated a draft, the Draft step in the PRD editor could lock itself the moment you moved on to Publish, leaving no way back. A generated draft now keeps that step open so you can always return to it.
In the stepped PRD editor, step 3 (Draft) unlocks once you've gathered workspace context. But if you chose to skip scanning and generated a draft anyway, the step stayed flagged as locked. It looked fine while you were on it, but as soon as you advanced to Publish, the Draft step greyed out and you couldn't click back to keep editing.
Now a generated draft always keeps the Draft step reachable, whether or not you scanned your workspace. Move on to Publish and back as many times as you like, the step you've already filled in stays open.
