Thank you for your comment.

The idea of time as fundamentally deterministic and reversible is deeply ingrained. It is a consequence of assuming that physical reality is non-contextual, meaning it is independent of the surroundings (or of the vacuum state). This is different from assuming objectivity from observers (which I certainly do).

In my Preprints article (linked in article), I propose a conceptual framework, in which exergy and ambient heat are objective but contextual properties of state, and irreversible time is fundamental. System time is a complex property of state comprising imaginary "mechanical" (reversible) time and real thermodynamic (irreversible) time. (In the Preprints article, I incorrectly describe thermodynamic time as measured by the production of generalized WCM entropy, but in my current submission to MDPI/Entropy, I correct this to the dissipation of exergy, which is equivalent to the 2nd Law's production of thermodynamic entropy.)

The time measured by an observer's clock is irreversible Reference Time. This is the time across which we measure velocities and events, and it is distinct from System Time.

All this is to say that Cramer's, Hawking's, and other interpretations that do not recognize fundamental irreversible time because they are non-contextual are, in my opinion, incomplete. Non-contextual interpretations are idealized special cases in which dissipation and irreversibility do not exist. Relativity assumes absolute-zero ambient temperature, and quantum mechanics assumes equilibrium. The WYSIWYG conceptual model generalizes these idealized special-case interpretations and adds objective contextual properties of state. it also defines irreversible dissipative processes as fundamental.
