Construction role

Cosmological redshift is read as base/refinement drift rather than as a purely Doppler or pre-imposed FLRW expansion parameter. The Hubble parameter becomes an orbit-depth / base-progression readout. This does not yet settle the empirical Hubble-tension question; it states the construction role: the observable expansion grammar is read from ${\tau }^1$-base dynamics rather than attached as an external cosmological background.

What this step earns

Redshift and Hubble readout is made addressable as Step 062 in the fine-grained Construction Spine routing layer.

• Routing scaffold. Detailed earned-output extraction is pending the source-map pass.

What this step does not yet establish

This route exposes the RC3 construction step for inspection. It does not by itself establish peer review, empirical adequacy, or final manuscript-level source closure.
