Is Objective Reality Truly Independent of Observation?

Many people here seem to share an implicit assumption: that there exists an objective reality independent of observation, and that this reality is fundamentally stable and absolute.

I’m not trying to deny that assumption. But I’d like to ask something more specific:

If reality is truly independent and absolute, how do we account for the fact that every access to it is mediated through a subject?

In other words, is what we call “objective reality” something that exists prior to all observation, or is it something that only becomes coherent through the intersection of perspectives?

Not asking for agreement—just curious how far this assumption can be pushed before it starts to shift.

If all we ever have is access through observation, what would it even mean for a reality to exist completely independent of any subject?
