Chapter 33: The Consumer Mixer: Uniqueness on (γ, η)

The consumer sector is the unique mixed sector on the (γ, η) metabolic fiber pair. A consumer carrier couples production and recycling channels to acquire both structure and energy from other Life forms. Signature rigidity of τ³ forces exactly one mixed sector: no other generator pairing admits a stable mixed Life loop. The consumer sector’s self-modeling capacity—SelfDesc applied to SelfDesc itself—opens the door to E₃ enrichment, making animals the bridge-head from biology to mind.
