the number the tru assigns to every particle — probability of being observed by a rational neuron. cyberank is focus materialized as a per-particle score fixed point of the tri-kernel: `φ* = norm[λ_d · D(φ) + λ_s · S(φ) + λ_h · H_τ(φ)]`. integrates exploration (diffusion), structure (springs), and…

the ranking module computes per-particle scores from the cybergraph. the output is cyberank the current implementation uses the tri-kernel: diffusion + springs + heat kernel. convergence guaranteed by the collective focus theorem. engineering specification for focus dynamics lives in cyber/focus
