I always keep a text file in the repo I'm working in, containing all my notes, and I'll periodically copy that document over to here. I'll link between the notes, the PR that i'll make soon, and more. This is spiritually similar to me speeding up the OpenStreetMap website test harness by 70% (sorta working in public/teaching/explaining/creating collateral)
PR associated with this work: @mastodon, Help the test harness run more speedily #29992
