Indigenous civilizations usurping the nests of Trial Civilizations to acquire the identity of a Trial Civilization—such a maneuver isn't theoretically impossible.
The Analysis Department of Human Civilization had already provided an answer.
They had attempted it, and the content of the attempt was straightforward.
That is, to formally recruit natives, making them members of the civilization!
The Civilization Trial's judgment on recruiting natives involves self-recognition, a requirement that is mutual.
It requires the civilization's own approval, and it's not just about gaining an identity: this identity needs to be recognized by the vast majority within the civilization.
In addition, the joiners themselves must also be willing, needing to wholeheartedly embrace their place as a member of this civilization.
Once these two requirements are met, the "cognitive barrier" caused by the Civilization Trial would be broken.
