The goal is to better and more consistently enable backtagging and figuring out pre game-year cr, so academy and promotion ages would be ideal if you are up to providing those (like which of the exams gave her chunin status, and then you can figure out if you knew someone from the exam).

I don't need or expect a timeline of any length. The people who provide that do so for their own sake.

Really what we want is what you have done ingame: test drive or meme threads considered canon.
