One-ness is a physical property and that's why we can see it. The magic happens when we call them all one, give it a symbol, and make them all equal. Now "one" has a unique existence of its own on a piece of paper on a mathematicians desk, scribbled alongside other unique symbols, whose relationships come complete with proofs. And the only question then is whether what was scribbled says something true, as in, something that aligns with the reality it came from, because that would make it useful.

Math is a map. Maps are only real insofar as being a map, and only useful insofar as being true.

The drawing of the streets may be drawn with your pencil from memory, but the truth your friend relies on to get them where they need to go is real. The paper and pencil are real. And the physics of the informative truth that transcends from the streets to the paper is also real. Computers are the machines we've built based on the physics of logic, abstraction, and meaning. A computational value is something that means something to something else.

We can see it, but does that make it a physical property or something that we impose upon the universe?

For the rest of your statement, I don’t know if we can easily define “true” or “useful”. Epistemology has been working on those concepts for a long, long time, and I don’t know if they’ve made much progress recently.

One-ness is a shape of a thing, much like triangle-ness or circle-ness. Shapes are physical, but they can be copied, unlike the things themselves. And when meaning is associated with a shape, that meaning can then be copied and read. So we can take "one-ness" which is physically measurable and identifiable, associate a new shape such as "1", and now we have a shape with meaning detached from its origin that we can copy, read, and communicate. The source is still reality, and this physical mechanism is what makes communication possible. Gather enough of these symbols and you have a language. Combine these symbols and you have a statement. Have anything that reads and reacts to statements and you have consequences. From DNA to protein, from grocery list to grocery bag, from tweet to insurrection.

Any combination of words can form a statement. So someone comes along and says let's agree on grammar. Then someone comes along and says let's confirm with nature whether statements actually align with nature before we call it a fact. This is modern science and the scientific truth. Scientifically, nature is the single source of truth and is all true. False only exists in the gap between a statement and nature.

I think facts, truth, unity, etc, are fundamental building blocks of our perception of reality, not reality itself. That doesn’t make truths or facts invalid. We all share some common perception of the universe, at a very low, fundamental level. I believe knowledge can be built on that foundation.

Not only do we share some common perception, we're also all real. We are part of the universe. So to say people are subjective or that imagination is imaginary or that reality is an illusion for the purpose of dismissing them from reality is all wrong. You need a model that is more inclusive that describes it all with physics as the premise. For example, a dream requires a sleeping biological brain full of memories drawn from physical experiences.

Truth isn't reality itself in the physical sense. But the word "apple" isn't an actual apple either in the physical sense. Yet, for the purposes of language, it is. And that is the exact extent to which truth is reality in language. When we claim truth, we claim to be making a statement of reality. If that statement includes God, then your reality includes God. If it includes only physical evidence, then your reality is based on physical evidence. We can align our realities scientifically by aligning them with science. But again, based on your life, your work, and your beliefs, your reality will deviate. That's just part of what makes us all unique.

But as you say, our unique realities are still valuable and real. Though error prone as they may be, they are real reality drawn from a real life. It's not separate just because they contradict. That's why our ability to communicate our truths is cital, and Free Speech is sacrosanct.
