These suggestions sound conflicting but I'll first try moving the piston without bleading the valve and hoping the piston stays depressed after I remove the spreader (on order 2 day Amazon).

This sounds accurate. I'm 100% sure the groove on the rotors is OEM. The ridge on the pads seems to be there to align them with the rotors. I think I busted some of the ridge off on the pads removing them originally, but 99% of the surface area for stopping is the flat part of the pads.
