So, that was excellent fun.
I think my favorite parts were the individual awakenings. They gave a clear and defined sense of the differences in each Vocaloid, and were imo quite powerful and engaging, particularly Gumi's. I also have to give significant props for the concept of the logs files acting as essentially residual memories. That was really well done.
I also deeply appreciate the deliberate lack of a "villain" in this. You'd already told us in the Featured Documents post that such was the case, but I was still definitely left wondering whether there wouldn't be at least some attempted shenanigans when Dr. Tsuji showed up at the final hearing. That, as well as Hinamura's response when Miku asked why he'd decided to join in on their side were fantastic. (As an aside, the annotation for how Gryph and Zoner intended to "handle" any potential complications was absolute gold)
