Construction role

Book IV develops physics as the carrier’s self-description on its own

-boundary fiber. Microphysical content arises from how the carrier reads itself through bipolar character channels, the four-atom idempotent grammar, and the sector holonomies inherited from Book III. Proto-time is explicitly not part of this fiber analysis: temporal progression, worldlines, and proper time live on the ${\tau }^1$ base and are developed in Book V.

What this step earns

Self-description on the $T^2$ fiber is made addressable as Step 045 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.
