>I just think before 2mugi, there was something else
That's kind of where I'm at too, if we're going with pure hypothesizing. Nothing to back it up at all, but I had a thought that Ring-hime was perhaps like a prototype control AI made before Mugi, but based upon the popular AiPri at the time (young Wanko-sensei). Her loss of memory would be due to wiping her memory before switching over to Mugi, like wiping your drive before installing a new OS, but some fragments remained and after a while they reconstructed into the Ring-hime we see now. Similar to Himari's affinity with Mugi, Wanko-sensei and Sarashina would have that same affinity with Ring-hime due to being based on the (young) old hag.

Throwing darts at a dartboard here, but hey, never know.
