A habitable zone moves with its star
The present-day orbit is only one frame. MIST stellar tracks and three named Kopparapu boundary prescriptions test whether a planet stays inside a modelled irradiation range through time.

What the analysis found
Most planets cannot support a time-resolved claim
The dominant climate result is missing support. Only a subset has the stellar age, mass, metallicity, luminosity and uncertainties needed for a continuous history. Among supported systems, model agreement and disagreement remain explicit rather than being averaged away.
