Worth separating two things here: the OPH technical papers (particle mass derivations, overlap consistency axioms, IBM quantum benchmarks) are very interesting and deserve scrutiny on their merits.
But Mueller has published addenda that go well beyond physics — Rapture, a "Karma Engine" where future observers implement hell for bad actors, Jesus as an "inserted observer," named public figures facing cosmic justice.
These aren't derived from the axioms; they're a messianic belief system wearing physics vocabulary.
The technical work may or may not hold up under peer review.
The addenda are a red flag about the whole project's epistemiology.
The problem is right in the prologue. “Every piece of evidence we have for objective reality is itself a subjective experience.” But people do independent experiments. And the results agree. That’s a much stronger statement.
OPH is a reconstruction program for fundamental physics. Spacetime, gauge structure, particles, records, and observer synchronization are treated as consequences of the OPH package rooted in overlap consistency on a finite holographic screen, together with the explicit branch premises stated in the papers.
