In short, I consider IRT is a hopeless muddle, though it
might be repairable to some extent --

Doubtful.

Have you ever tried to pin down what 'absolute' means to him?

It is kind of like what most people mean when they say 'relative' except
that 'absolute motion' is alway vertical wrt the local gravity.

I did note that, and that does pose a pretty problem which is not SR
related (since gravity kinks things in the reference frame).

You always misinterpreted what IRT says. IRT says that frequency shift of a
light ray is the result of absolute motion of the detector wrt the light ray
or interpreting the other way the arrival speed of the light ray is varying.
On earth when a source is in the vertical direction the detector directly
under the source detects red frequency shift. This means that the the
arriving speed of the light ray is slower than c.
