τ-Einstein identity

The macro field identity is written here as

R^H=κ_tau T,

with κ_tau serving as the τ-gravitational coupling readout, not as an imported PDE. Here H is the holonomy/curvature superscript, not an abbreviation for the Riemann Hypothesis. Its role is to balance curvature-side holonomy data with matter/stress defect data inside the same carrier grammar. Ordinary Einstein gravity appears as a chart/readout shadow of this identity, not as an assumed background equation. Classical GR tests are therefore treated as readout checks of the τ-Einstein structure rather than as axioms of the construction.
