Abstract
The paradox of deuterostome body plans is that genome an-alyses indicate deuterostomes are a group with strong kinship, yet they are an assemblage with what appear to be distinctly different body plans. The two major deuterostome groups, chordates and ambulacraria, are allied by features of their anatomy that do not include the nervous systems. Here I review data emerging from neuroanatomical studies that in-dicate echinoderms and hemichordates have two distinct parts to their nervous systems. In this brief perspective, I propose the hypothesis that in the ambulacraria the two parts are separated spatially and temporally over life history stages, whereas in chordates the two parts are united in a single central nervous systems. This view provides a means of in-cluding neuroanatomy in a common deuterostome body plan. THE DEUTEROSTOME BODY PLAN PARADOX

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
