Tarski geometry and wave-type causal precursor

Coarse-graining the ultrametric address topology along the geometric readout produces an internally Tarski-style Euclidean geometry: incidence, betweenness, and congruence are recovered from address comparison and readout-stability, not imposed as primitive spatial relations. In parallel, the split-complex relation j^2=+1 supplies a hyperbolic, wave-type causal precursor. This is not yet physical time; it is the hyperbolic algebraic precursor that later readout layers may use.
