One way is to try to summarize the project as you see it from the now, then use links to those pieces as support for the exploration. These could be created using certain words (as pretty links) within your summary connecting to new notes where you curate collections of the relevant pieces within specific contexts, or even using similar summary methods recursively, or directly embedding headings from those daily notes. And if the daily notes aren’t delineated with headings, either add them or use block references.
I guess what I am trying to say is that I often make this same process harder on myself by becoming more concerned with having the past notes do the talking and it ends up obscuring the true newfound message, which may be more important than its history.
Good question and good luck luck! Thanks!
