But yeah, it would make the most sense for her to write it down for her descendants to prepare for it after she died, assuming that she wrote it pre-fruit, so before she's immortal, or something like that. That would go against what the databook said when the otsutsuki clan came to earth and the clan migrating to the moon after kaguya's defeat. This series is no stranger to retcons though, so it's possible. I personally think she kept documents of her enemies(I still don't think shiki's are strong enough to take down kaguya, so there being stronger beings makes some sense)
