Chapter 34: Eukarya as Fiber-Enabled Regime, Not Sector

Eukarya is a carrier technology, not a sector identity. The eukaryotic cell—with its nucleus, endomembrane system, mitochondria, and cytoskeleton—provides the internal architecture that enables running any of the five Life sectors, including the mixed consumer sector on (γ, η). This chapter formalizes Eukarya as a fiber-enabled regime , develops the critical 2nd Edition correction from the (α, π) mixer placement to the (γ, η) mixer, catalogs the four eukaryotic innovations that internalize the metabolic fiber, and demonstrates that the technology is sector-agnostic: photosynthetic eukaryotes run the source sector, saprotrophic eukaryotes run the closure sector, and predatory eukaryotes run the consumer sector.
