Emergence in Effective Field Theories - Philsci
... An effective field theory (EFT) of a physical system is a description of the system at energies low, or distances large, compared to a given cutoff. EFTs are constructed via a process in which degrees of freedom are eliminated from a high-energy/short-distance theory. Formulating a concept of emerge ...

The saving grace is that the family of dynamical trajectories through a given point, although they in general disagree radically about which point represents the future state of the system at a given time, do agree about which gauge orbit this point lies in.
