The board has two fictional revision states and three reference questions: drawing, sample and supply file. A marker can be unknown, attached in the demonstration or carried from a previous revision. When the selected revision changes, an attached marker becomes stale. This makes the missing review step visible without declaring any actual document received, any part accepted or any manufacturing release completed.
Keep the change itself and the reference response distinguishable. Ask the provider what changed in the controlled definition, which records remain relevant and which must be replaced. Preserve the earlier file identities in the actual project history instead of silently relabelling them as current. A useful sourcing website can organise that handoff while leaving the real review and approval with the responsible parties and their current evidence.
