I have put your 4232 hold-out machines through my Deciders, and got the number down to 694. See bbchallenge/Holdouts at main · TonyGuil/bbchallenge · GitHub for details, including Decider Verification Files.
My broader segment-matching criterion for the HaltingSegments Decider fails to find any new non-halting machines here. So if @UncombedCoconut’s results are correct, there is no need for it.
