Construction role

Book IV also fixes the semantics of core microphysical quantities. Localization is an $E_1$ hom-object locus; momentum is the defect-transport invariant conjugate to localization; mass is stable defect-bundle calibration; energy is state/address/defect-budget readout; charge is boundary holonomy or winding obstruction; spin and polarization are fiber-mode readouts. Classical force is not primary here: it can be recovered as an effective response or gradient readout, but it is not a primitive $E_1$ invariant.

What this step earns

Physical quantity semantics is made addressable as Step 053 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.
