Protocol for Spacetime Engineering： An Operational Framework from Relational State to Observable Effects

Abstract

This paper establishes a complete operational framework from "relational state" to "observable physical quantities," aiming to advance "relational operation" from a theoretical concept to an experimentally testable engineering hypothesis. Based on the Trinity Unity framework and relational network simulation experiments, this paper proposes four computable and measurable relational state indicators (relational density, cross-level coupling ratio, manifestation-concealment switching rate, and relational locking degree), and establishes their mapping relationships to four groups of observable physical quantities. This paper further designs a two-system cross-validation experiment (atomic clock array + gene expression system). If two independent systems produce consistent responses to the same relational operation, the effectiveness of relational operation gains cross-system corroboration. This paper also provides a standard operating procedure and the structure of a parameter database, enabling relational operation to become a repeatable and accumulative engineering practice. The core contribution of this paper is: transforming the theoretical thesis that "spacetime is the presentation of relations" into a set of testable propositions and executable experimental protocols.
