Reflection is looking back at something you did, working out why it went the way it did, and deciding what to do differently. It is how experience turns into knowledge you can use again.
Something you will recognise in three months' time, such as “The bug that reached the main branch”.
It may have been deleted, or the link may belong to a different browser. Reflections are stored only in the browser they were written in, so they do not travel between devices unless you export and import them yourself.
