Status: constructed six-domain visualization and engineering ontology.

Assign six normalized scalar values
$$ \Omega_1,\ldots,\Omega_6 $$
to the six faces of a cube. A composite score may be defined by
$$ \Phi=\sum_{i=1}^6w_i\Omega_i,\qquad \sum_iw_i=1. $$
The cube is therefore a categorical carrier for six domain variables.
Where contraction is intended, the canonical stable operator is
$$ x_{n+1}=(I-\varepsilon K^\dagger K)x_n, $$
not the generic use of $I-\varepsilon K$.
The plate is useful as an interface for mathematical formalism, computation, visual systems, AI, domain bridging, and network dissemination.
