Gantry Twist & Bed Mesh Issues on RatRig V-Core 4 500
Agree with the PEI plate comment, I had bad gantry twist with my provided RatRig 500 plate. I bought a plate from Lukes Laboratory and without any changes, my gantry twist was fixed. I also found that just by adjusting the feet, I could adjust the bed mesh.

VOAC calculating offset wrong by the same amount every time
I had a similar issue where my Y was good for the IDEX and my X was off. I did the IDEX calibration test at all 4 corners of my 500 as well as the center and it was noticeably tracking worse farther away from teh VAOC. In my case, it ended up being that I had my X-axis belt tensioners adjusted differently (trying to get the IS graphs the same). Once I adjusted the belt tensioners to the same length (and have exact same belt lengths as suggested)

Cant bring up the left back corner
Have you tried adjusting the printer feet? I was able to at least level out the corners on mine by adjusting the mounting feet. Didn't resolve the bed/gantry warp at temperature, but improved the twist anyhow. I also saw some improvement swapping to another PEI build plate, improved my gantry twist as well.

Regular surface distortion pattern towards end of larger first layers VC4
You aren't alone, I have also been having first layer issues and figure it's got to be because I am a novice coming from a Bambu. I don't have words of wisdom here since I am still battling the same fight as well, but will be listening to see if some of the smart folks on here can help. I do have high gantry twist at 130 micrometers that may be my issue. I also have struggled with getting a good bed mesh with it cold around .280 on a vc4 500. Will stay tuned to see what helpful advice comes your way.

Just fyi for those that have the same issue, I ended up flashing a new SD card and reloading into the raspberry pi and going through updates again.
