Record where each product rule comes from.
A reviewable source is easier to maintain than an unexplained restriction.

Give the rule a product reason
A dimension limit or option dependency should have an agreed source. Name the relevant product sheet, approved range, or product owner. The configuration team then has a way to check the rule without turning a remembered sales conversation into a specification.
Include a useful example
Write a valid example and a case that should be rejected or sent for review. These examples make the rule easier to discuss across product, sales, and implementation teams. Keep the expected explanation beside the case so the interface can describe the restriction clearly.
Plan the update responsibility
Decide who reviews a change when the range develops. Product information, price logic, and customer wording should be updated together where they depend on the same rule. Recheck the relevant examples before the revised range is made available.
One useful question.
Choose one dependency in your range. Can the reviewer find its source and two example cases?
