Coherence kernel

The bare kernel is fixed as five ordered generator symbols α < π < γ < η < ω, one progression/application operation ρ as the sole primitive operation, and the constraints K0 – K6. K0 prevents τ from becoming one object among its own objects; K2 makes ω the absorbing fixed point (ρ(ω)=ω); K3 – K6 generate and close the four finite rays while forbidding premature collapse into ω (K5 in particular: ρ^n(g)≠ω for non-ω g). This is the proposed minimal symbolic kernel: not yet geometry, number, space, or physics, but the least constructive source claimed to carry them. The E0 claim is minimal constructive sufficiency, not classical model-theoretic categoricity.
