Module supplies the Minkowski metric forced by the T0-T8 chain, expressed as a map from four indices to reals. Researchers linking lattice J-cost to Einstein equations cite it as the flat-space base case. It consists of definitions and equalities that instantiate the chain output with no internal proofs.

claimThe RS Minkowski metric $\eta : \mathrm{Fin}\,4 \to \mathrm{Fin}\,4 \to \mathbb{R}$ with diagonal entries $(1,-1,-1,-1)$ and vanishing off-diagonal entries, as forced by the T0-T8 chain.

background

The module sits inside the Relativity.Geometry hierarchy and imports the Tensor scaffold (explicitly marked outside the certificate chain), the Metric definitions, and the Curvature module whose doc-comment states it derives Christoffel symbols from the metric. The local theoretical setting is the flat spacetime metric required by the T0-T8 forcing chain in Recognition Science, with the supplied doc-comment identifying the object as the RS-style Minkowski metric.

Sibling declarations in the same module introduce rs_eta, rs_minkowski and their equality lemmas, establishing the concrete component values and symmetry properties. This metric then serves as the starting point for curvature calculations and the discrete-to-continuum bridge.

proof idea

this is a definition module, no proofs

why it matters in Recognition Science

The module feeds the Geometry aggregator and the DiscreteBridge module. The latter's doc-comment states it connects J-cost lattice to quadratic defect, lattice Laplacian, Ricci scalar, Einstein tensor and the Einstein field equations. It therefore supplies the flat-space foundation step required by the T0-T8 chain for the Recognition Science derivation of general relativity.
