OK so after digging through the code, I have at least a rough guide for all the endings:
-Submission needs 60 paranoia, 15 eyes, and less than 20 certainty when you buy "Let it in"
-Control you need either 35 control and under 30 paranoia, or your control has to be higher than paranoia x1.5 when you buy "define reality"
-Refusal, the clickable square will start glowing and beg you to keep going. just don't do anything for a minute and the ending triggers.
-Integration, you need like 20-40 fragments to buy the upgrade that gives that ending
-"Final" ending once you get the first 4, you'll need a lot more fragments to buy a few more upgrades.(might also need to buy the 3 upgrades for integration, submission, and control to get it to fire as well, I'm unsure.
still uncovering the new fracture endings, will add to it later.
