To aid in my understanding, could you at a high-level document what classes and relationships of LabKey may map to known Design Patterns?

One Design Patterns book I've thinking of in particular that you could compare with is:
 Patterns of Enterprise Application Architecture bye Martin Fowler.

And you need not worry about documenting the design patterns used by other frameworks that LabKey buils on - Spring, Struts, etc. - because those are documented other places.

Thanks.
