Abstract
The impossibility of describing measurement in quantum mechanics while using a quantum mechanical model for the measurement machine, remains one of its central problems. Objective collapse theories attempt to resolve this problem by proposing alterations to Schrodinger's equation. Here, we present a minimal model for an objective collapse theory that, in contrast to previous proposals, does not employ state dependent stochastic terms in its construction. It is an explicit proof of principle that it is possible for Born's rule to emerge from a stochastic evolution in which no properties of the stochastic process depend on the state being evolved. We propose the presented model as a basis from which more realistic objective collapse theories can be constructed.

Report
This is an excellent paper. The authors ideas are novel and compelling. The manuscript is well written and the citations are logical and plenty for a paper of this size.
I only $\textbf{suggest}$ the two changes listed below. However, the paper would be good with or without the suggestions.
1: Specify and elaborate specific experiments of interest to the authors. Although the citations are specific experiments, it would be helpful if the authors could summarize briefly how the experiment can shed light on their collapse theory. Even one single example so that the reader doesn't have to read and process multiple citations. One of the unique things about this method, is how connected perturbations of the Schrodinger equations are to experiment. I think slightly more emphasis on this would go a long way.
2: The second to last paragraph in section IV is quite remarkable, yet easily lost! I might suggest splitting this paragraph into two separate paragraphs or possibly another subsection, for any reader that is skimming. A graph of N vs. $\varepsilon \tau_r$ might be a really exciting way to see the relationship of system size and correlation time, and how these numbers actually stack up.
