Two adult worm maps gave wider stable growth intervals than sampled degree controls in a positive linear model

We tested whether circuit arrangement changes stable transient growth beyond labeled input and output degrees in two adult C. elegans chemical wiring maps. A positive linear model used 180 common neurons, equal binary weights, equal leak, and spectral-radius normalization. The exact stable growth widths were 0.2418 and 0.2189 on the normalized gain scale. Each exceeded all 199 degree controls at both 20 and 100 swap attempts per edge. Mean long-control widths were 0.2043 and 0.1862. Synapse-count weights kept growth intervals but reversed the map order. All 796 control graphs, source graphs, scores, curves, code and checks are supplied. These are finite graph-ensemble and model results. Assumed positive coupling, Euclidean norm, partial maps, two adults, and controls without spatial, class or reciprocity constraints prevent claims about measured neural amplification or adaptation.
