A lore question about Upwell Structures

Of the current upwell structures that exist, we have ECs and Citadels. Lore-wise, they are the premier products of the Consortium. We can configure them with clone rated medical facilities, powerful reprocessing arrays, and versatile manufacturing centers. Yet, despite this knowledge, we don’t know much of what the internal structuring is aside from the internal docking cradles, and knowing that multi-millions of baseliner populations can live in any given structure.

I’m of the opinion that they are all largely modular in how they can be sectioned, but I’m curious what others think.

So the question is, what would be the quote unqoute ‘standard’ lore configuration internal sectioning for Upwell Structures?
