Construction role

Quantum mechanics enters as a limitation of simultaneous address resolution on

×_f $T^2$, not as a postulated Hilbert formalism on a background space. The CR-address grammar yields discrete spectra, noncommuting observables, state-space structure, and measurement interfaces because incompatible fiber-addresses cannot be resolved together. The quantum state is therefore a readout of admissible address structure; it is not an additional ontology placed on top of the carrier.

What this step earns

Quantum mechanics as CR-address obstruction is made addressable as Step 051 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.
