The Library is the reference shelf: commands, decisions, and setup steps that should be easy to find later.

The Learning Log is the trail behind it: what I was trying to do, what I misunderstood at first, what I tried, and what finally turned into a repeatable guide.

Most entries will be problem chases. Some will be larger build stories. Either way, the useful ending is the same: a new how-to, or a sharper version of one that already existed.
