Unserious Exocolonist Theory

The Convergent Domain is somehow the Vertumna human colony itself, trapped in a much longer time loop than the one Sol is experiencing. The Gardeners know this but do not want the human colonists to know this so they keep up the pretense that their actions with regards to the colony are invasive species control rather than trying to stop the time loop before it begins again.

Sol's actions on a golden playthrough stop the humans from becoming the Convergent Domain again. The Tangent's Cure/Destroyed the Array endings accelerate it.

Thoughts on this? I'm aware it's not exactly canon compliant but I woke up with it rattling about in my brainpan and had to get it out.
