A QFT organized as all local operators allowed by chosen degrees of freedom and symmetries, ordered by powers of a high-energy scale.

This is an authored directed relation from the source endpoint to the target endpoint.
EFT power counting is organized by ratios of physical scales.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Effective field theory is a scale-organized use of QFT with a specified cutoff and degrees of freedom.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.

This is an authored directed relation from the source endpoint to the target endpoint.
Fermi-liquid theory is an effective low-energy framework for interacting fermions near a stable Fermi surface, organized around quasiparticles and symmetry-allowed residual interactions. Systems without long-lived quasiparticles do not lie in this specialization.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.

A Wilsonian effective action is a scale-dependent action representation of an EFT after integrating out modes above a cutoff.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
