Construction role

In order-readout, the kernel is not a single generated ray. It is a typed four-block stack

.

This shape is an order-readout analogy, not imported ordinal theory. The classical ordinal ω would correspond only to the first post-α boundary position; the τ-symbol ω is the global absorber/top element after all four typed rays. The stack is therefore analogous to a finite ω-block shape, but each block carries a different fold regime. This is the E0 precursor of the later 4+1 sector template.

What this step earns

Four-block order readout is made addressable as Step 004 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.
