What this surface does

This is the manage/edit surface for one wheel record.

It uses the same five-step wizard as create, but the screen loads an existing backend row first and then changes its behavior depending on publish state.

How manage mode behaves

• If the wheel is still unpublished, the final submit action is Publish Wheel.
• If the wheel is already published, the final submit action becomes Save Changes.
• Step action labels change too: published wheels use Save Step, while unpublished wheels still use Complete Step.
• If the backend record cannot be loaded, the screen falls back to Wheel not found plus a button back to the list.
• Segment bonus mapping still points into the reusable bonus catalog, but manage mode does not edit the bonus records themselves.

Common caveats

• Updating a published wheel still re-runs backend publish validation. Missing required title or segment data can block the save.
• Save Step persists partial changes, but the wheel remains unpublished until the publish path succeeds.
• Preview links are still helpers only. They are useful for checking URL composition, not for verifying publish state.
