In structure review, if packaging structure still means 'engineering owns structure, brand owns graphics,' the result often is: structure is already speaking, graphics say something else. More reliable: run structure proposals through the same brand-principle questions, and lock this choice into structure review.
Packaging structure must first stop being 'engineering owns structure, brand owns graphics.' In structure review, if you can't stop saying this, it directly produces: structure is already speaking, graphics say something else.
The continuing part can be minimal. Minimal is how you hold the line that structure proposals must pass through the same brand-principle questions.
Structure proposals must pass through the same brand-principle questions. Fail here, and packaging structure stays as 'engineering owns structure, brand owns graphics.'
Ambiguity usually leaks from well-meaning additions. People add packaging-structure conditions to cover more cases, and quietly rewrite it back to 'engineering owns structure, brand owns graphics.'
Each addition, if you don't look back at the question, makes the boundary harder to enforce. The question is: structure is already speaking, graphics say something else.
Negative lists beat adjectives. Write when packaging structure cannot be used, and the team knows 'structure proposals must pass through the same brand-principle questions' isn't a slogan.
Keep the list short—short enough to read completely before tooling.
Structure review contains overreach, not collects inspiration. Overreaching ideas can exist, but can't pose as packaging structure.
It holds because design and engineering move together, and both can say no.
When overreach happens, don't just revise one deliverable. Return to structure review and add the condition this time bypassed.
Then re-check with the same question: does this structure answer the questions in brand principle?
From non-negotiable elements to fieldable tools—each layer answers one question, avoiding rewriting packaging structure as 'engineering owns structure, brand owns graphics.'
This layer defines what in packaging structure cannot be negotiated.
This layer reduces packaging structure to checkable conditions.
This layer defines what packaging structure can vary across different contexts.
This layer gives packaging structure to the people using it, with exceptions noted.

In structure review, mark when packaging structure is actually invoked—don't start from rewriting 'engineering owns structure, brand owns graphics.'
Use structure review instead of longer explanation—retain only what supports 'structure proposals must pass through the same brand-principle questions.'
Before tooling, ask only: does this structure answer the questions in brand principle? If you can't answer, it's not yet a decision.
Design and engineering together. Without a maintainer, packaging structure gets quietly altered in conflict.
In imagery guidelines, if photography style is still described by filters and settings, the result is often settings that break on a different device, while the subject was never defined.
In visual system extensions, if illustration is still applied everywhere, the result is often that illustration starts doing the logo's job of recognition.
In an interface or film, adding motion simply because something can move usually interrupts reading without conveying anything new.
