Step 090 — E₂ export to E₃

Book VI closes by exporting six completed structures: the Life predicate, the 4+1 sector template, genotype/phenotype predicates, the ω-germ question, Life basins, and substrate-agnosticism.

Construction role

Book VI closes by exporting six completed structures: the Life predicate, the 4+1 sector template, genotype/phenotype predicates, the ω-germ question, Life basins, and substrate-agnosticism. This marks the structural limit of $E_2$: life can carry and decode code, while the next layer asks how a living system models that fact.

What this step earns

E₂ export to E₃ is made addressable as Step 090 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.

Source anchors

• Full Construction Spine RC3 whitepaper source (papers/whitepapers/panta-rhei-construction-spine-e0-e3/main.tex:1156)

Manuscript extraction state: Detailed source anchors pending extraction.

Anchor classification: whitepaper source resolved; manuscript extraction pending; Registry extraction pending; TauLib extraction pending.

Formalization and verification

Registry links: Registry extraction pending.

TauLib modules: TauLib module extraction pending.
