As John Tan said before,

“When we authenticate radiance clarity directly, we have a first hand experiential taste of what is called the "ultimate free from all conceptual elaborations" but mind is not "free from conceptual elaborations".”

Wrote some time back:

Seeing selfness or cognizance as a subject and phenomena as objects is the fundamental elaboration that prevents the taste of appearances as radiance clarity.. then even after anatta, there are still the subtle cognitive obscurations that reified phenomena, arising and ceasing, substantial cause and effect, inherent production and so on.

So elaboration is not just coarse thinking like labelling but to me is like a veil of reification projecting and distorting radiant appearances and its nature.

Another way to put it is that the fundamental conceptual elaboration that obscures reality/suchness is to reify self and phenomena in terms of the extremes of existence and non existence through not apprehending the nature of mind/appearance.

….

If you mean just authenticate radiance clarity like I AM, then it’s just nonconceptual taste and realisation of presence.

That moment is nondual and nonconceptual and unfabricated but it doesnt mean the view of inherency is seen through. Since fundamental ignorance is untouched the radiance will continue to be distorted into a subject and object.

"The process of eradicating avidyā (ignorance) is conceived… not as a mere stopping of thought, but as the active realization of the opposite of what ignorance misconceives. Avidyā is not a mere absence of knowledge, but a specific misconception, and it must be removed by realization of its opposite. In this vein, Tsongkhapa says that one cannot get rid of the misconception of 'inherent existence' merely by stopping conceptuality any more than one can get rid of the idea that there is a demon in a darkened cave merely by trying not to think about it. Just as one must hold a lamp and see that there is no demon there, so the illumination of wisdom is needed to clear away the darkness of ignorance." - Napper, Elizabeth, 2003, p. 103"

It is important however to note that Gelug and non Gelug authors may have different definitions of conceptualities, as John Tan pointed out years ago: “Not exactly, both have some very profound points.  Mipham "conceptualities" is not only referring to symbolic layering but also self-view which is more crucial.  Mipham made it very clear and said the gelug mistake "conceptualities" as just symbolic and mental overlay, which is not what he is referring then he laid down 3 types of conceptualities.  Same for dharmakirti also...there is the gross definition and the more refine definitions.”
