An idea lands best when it says what you were trying to do, not only what to build.
What you were doing. The task, in your own words, with the notes and the vault it involved.
Where numen got in the way. The step that was slower or clumsier than it should have been.
What you would have wanted instead. A shape, not a specification. We will argue about the details here.
What you do today. The workaround, if you have one. It tells us how much the gap costs.
One idea per topic. Two ideas in one topic get one reply and the second is forgotten.
