Ugh, the things you do when you post a chapter late at night before going to bed.
I'd left out several entire paragraphs from Sharik Yangila's monologue, because her interlude was also supposed to be a reader's introduction to Vilani society as seen by an Imperial grandee and not just by Terrans guessing from the outside. Because I'd already known this stuff, and I was tired enough to forget that the readers didn't and the entire reason I was posting the monologue was to get an excuse to also post the context. So, went back and inserted them.
The short version is that Vilani society is indeed a deliberate social engineering project - it's basically Confucianism if Confucius had had access to the social and psychological sciences of an advanced interstellar society to help him design it, as well as generations of other psychologists and sociologists and political science majors working on refining the design, as opposed to being one ancient Chinese genius who had nothing to work with except his own preconceptions and intuition.
And that's why they don't innovate. It's not that they can't, it's that they've gotten their tech as far as it needs to get to sustain their empire and they deliberately don't take it any further. And they've been doing this for so long that most of them don't even think about it anymore.
Remember when Lt. Prescott was telling Sophia how Vilani ship captains worked off their tactical libraries instead of innovating, but the libraries still worked because they contained centuries' worth of experimental results?
She was right. And that's how Vilani society does basically everything.
