Does describing a universe make it exist?
Writing a novel does not give its character a separately operating brain. The essays distinguish a description from a realization whose actual dependencies preserve the described updates, records and interventions. A movie can match one history while failing that test: change the represented memory and the next prerecorded frame stays the same. A genuine implementation must respond through the specified organization. OPH then makes the stronger ontological proposal of intrinsic realization: a complete inhabited structure's internal dependencies constitute its operation without an external host or clock. That is a philosophical commitment beyond mathematical consistency. The ink does not create the world, and proving a finite implementation lemma does not prove that every consistent mathematical description is physically inhabited.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
To understand OPH and check every step yourself, start with the free book Reverse Engineering Reality. It builds the theory from the ground up, and the OPH Notebook answers your questions while you read.
