Ontological Bedrock: The Simple Rules Everything Must Follow to Exist

This paper finds the complete, unavoidable foundation for clear, stable existence, the rules any thing must satisfy in order to exist as a distinct, recognizable entity. No outside starting points, no hidden assumptions, and no fine print about where it applies. From one observation, something clearly and stably exists, we derive exactly three building blocks (a space of possibilities, a selection rule, and allowed ways to change while staying itself) and two survival rules (the self-consistency rule and the resource rule). We prove that Total Nothingness fails both survival rules simultaneously and that Leibniz’s question rests on a false assumption.
