Require complete design artifacts at the finish handoff

Name token-bearing DESIGN.md and its sidecar in the parent handoff while shortening the paragraph. Keep spec, token, sidecar and write-boundary gates; report wrapper coverage separately.

Validation: one Claude redesign retest wrote both artifacts; saved-output replay passed artifact checks (live assertion first failed on wrapper coverage). Default tests, source build and skill validator passed. Remaining token-accuracy limitations are documented.

AI assistance: Codex, under maintainer direction.
