Definitely does not match the event described:
The holographic chart projector was added in Frontiers, which released in 2021. The video in which Kusamoto found the Enzanthe XI system was posted on May 17, 2022. It was the second video in what was supposed to be a series of three (or maybe more). The first video was released on Apr 24, 2022. He definitely recorded both videos after the events of Waking Titan (much of the first video references Waking Titan contacting him in stream.
So yeah, maybe the Galactic Hub founding, maybe something else, but definitely not Kusamoto’s discovery of Enzanthe XI (and as a result, Tuscon)
