I disagree about your claim re: decoherence. Decoherence is just when any informational aspect of a system leaks such that the mind of an observer can update it’s state of knowledge to know which Everett branch it had been on all along. Nothing “splits” .. you just discover which version of “you” that you are.. which of the continuum of possible outcomes your personal measurement happened to see. Likewise I think you are incorrect about your discreteness claim. I agree with you that QM suggests the nature of reality is fundamentally discrete, but that reality also places the Born rule as a continuous mixture model across discrete states, and this is specifically what allows there to be a continuum of universes of every measurement regardless of whether the outcome is continuous or discrete.. like reality’s own Lesbesgue-Stieltjes measure.
