One challenge I've always had with having many concurrent project tracks is how to name them so they are distinct in my head. I made instrumental music so there's no lyrical line to hook into. Using "created at" datestamps for filenames is not great, but neither is obscure codenames.
I also make instrumental music, and I have this same problem. What I do is: find a word or phrase that matches the rhythmic phrasing of my main melody. That becomes the working title.
An example is how Paul McCartney’s original title for “Yesterday” was “Scrambled Eggs,” since those words fit naturally over the start of the melody.
You can follow the "correct horse battery staple" method the author referred to in the article. Another handy tool is a BIP39 seed generator (https://iancoleman.io/bip39/), but use the generated seed as a small pool of candidates that might catch your fancy. "hockey rival" or "pepper garment" or "frozen artwork" could be project names.
You can always go full Danger and just title tracks with the time you finished them at
