Did some quick research on "architecture terms", since I feel like this is a good metaphor. The word Juncture came up and is interesting. Here's the description:

Juncture: This is how different materials intersect, which ultimately influences how the building will age or if any maintenance issues will come up. If the juncture between the building siding and a window isn’t correct, it’ll cause leaking.

I think there's an interesting parallel there – where different materials meet – and how design and code meet.
