I really like the verbiage of “Pergola Alignment” as a concept. Putting knowledge creation on rails through systemic patterns that lead to insight is a really cool concept.
If you haven’t yet, take a look at the update I did for this year, as I took a similar route to you in terms of adding sub-folders: 2021 Seedbox Update.
It would be interesting to see more concrete examples of how you’re using the “bricks” and “pergola” ideas in practice. I am going to experiment with my understanding of the metaphor as well, and see what happens. 
I hope you’ll report your findings!
