There were no problems before starting the work other than the brakes were just worn
Now I’m thinking that maybe the master cylinder decided to bite it. So, I put a new master cylinder in it (bench bled before install) and while in there paid attention to the booster and it was clean…no fluid in it either in the bay or cabin (as a reminder everything worked just fine before the brake job). Rinse and repeat bleed steps. Ran the DSC bleed schedule several times until I was happy with the lack of air coming out of the lines. Started car and once again it flew the finger and kicked me in the jimmy….still no brake pedal.
I am still researching across the forums and in the next couple of days will have my own machine running the GT1 suite so maybe I can utilize the TIS for info, but for now I am really leaning on you guys. Please, I’m literally about to pull the hair out of my head and at this age in life I’m afraid that it will stop growing back at any minute!
Thank you guys for any and all advice!!

There is probably just air still caught.
I would get a long length of clear tube and go from each bleeder in turn, with the tube going back to the master cylinder. Then open up the bleeder, and pump continuously watching the fluid until there are no bubbles.
You can do it endlessly without having to worry about running out of fluid, and you’ve got all new fluid and most of the components ( except abs) so isn’t much a risk of contamination.
Eventually you’ll get the air out.
It’s possible when you left it open for so long air got into abs or other hard to reach places, but doing it a loop will get it out eventually
