What exactly are these "points in time"? This is important for me to
judge what cosmological stages these models refer to, and whether
they correspond to the same stage(s) mentioned in the Astronomy
article.

How much of this "knowledge" is hard empirical facts and how much
is theory?

LH>Two models: M1 and M2.

Which one of the above models is the "non-interventionist' one?

How do they evaluate what is an "error"? Naturalistic assumptions would
make any interventions by an Intelligent Designer look like "errors".

See above re "error bars". Naturalists cannot claim that there was no
intervention while their own non-interventionist models contain errors.

While there is a human inteligent designer's *choice* of initial conditions this
supports an interventionist (*not* a non-interventionist) model.

Disagree. To the extent that the input data at critical points is chosen
by a human intelligent designer, rather than generated by the output of
the previous model, it still supports intervention, rather than non-
intervention.

LH>(Doesn't preclude it, either.)

On the contrary, it is the *non-interventionist* models that are at present
precluded. Your chosen example above requires human intervention at critical
points. When cosmological models require *no* human intervention, then (and
only then) can you claim that such models support non-intervention by an
Intelligent Designer.
