Hi Jochen,
My May 6 response to your question -- "Your notions regarding---if I interpret you correctly---an inherent thermal 'noise' making the acquiring of perfect information about a system impossible remind me of Nelsonian stochastic mechanics. Is there a connection?" -- was at best misleading.
Thermal randomness applies to random fluctuations in energy levels, as defined by Boltzmann's partition function at a given temperature. In my dissipative dynamics conceptual model, thermal randomness is contextually defined at the system's positive ambient temperature(*). The randomness of ground-state energy is "irreducible," meaning its statistical description is complete and reflects perfect information. There are no hidden variables. So--I do not see any connection with Nelson's stochastic mechanics. Further discussion can be found in my Medium essay, Reinventing Time.

(*) Conventional interpretations (conceptual models) define thermal randomness either at absolute zero (deterministic mechanics) or at the system temperature (thermodynamics) in order to avoid contextuality.
