Numeric ID groups raised mean S response to LM drive from 0.138 to 0.257 in one human foveal model with 2.5 nS leak and 136.364 pS per weight unit
We tested cell identity in one released human foveal contact table. All 1,141 contacts defined 717 named pairs among 310 cones and 23 rods. The numeric segment fields gave only 263 groups for these 333 names. Four groups combined a numbered S-cone unit with LM-cone units. Six combined rods with cones. We kept all contacts and compared two passive electrical models. Each named unit had an assumed leak of 2.5 nS. Gap conductance was 136.364 pS per recorded weight unit. All LM units received unit drive. S units and rods received zero drive. Mean voltage at the 16 numbered S units was 0.137657 with separate names and 0.256668 with equal voltage within numeric ID groups. Group leaks and currents were summed. At zero gap conductance, ID groups still gave a mean S voltage of 0.135417. All 72 tested leak, coupling and candidate-label settings gave a positive mean rise. Independent readers and current equations agreed. The original simulator reads the names; this audit does not show an error in its published runs. The data do not establish why numeric IDs repeat or measure human colour vision. The contribution is a complete graph of the released named units, an identity audit, a model test, and code for reuse. Source data, credit, hashes, figures, results and repeat instructions are included.
