If everyone agrees on something, does that make it true?
A crowd can agree because everyone copies the same mistake. OPH's technical agreement has stronger requirements: comparisons have defined interfaces, protected evidence cannot be revised merely to make agreement easier, and the permitted repairs must satisfy their stated conditions. Even then, schedule independence means that admissible repair paths from the same start reach the same public result. It does not mean every starting point gives one answer, or that the answer describes our Universe. An inconsistent specification may have no solution; incomplete evidence may admit several. Physical truth requires the records and interventions to match what is measured. The essays therefore treat criticism and dissent as ways to expose a bad constraint or missing observation. Silencing a participant is no substitute for resolving the disagreement.

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.
