Abstract
Unlike Helkesimastix faecicola and H. major, Helkesimastix marina is marine, ingests bacteria, is probably also a cannibal, and differs in cell cycle ciliary behaviour. Daughter kinetids have mirror symmetry; pre-division cilia beat asymmetrically. We sequenced its 18S rDNA and studied its ultrastructure to clarify its taxonomy. Helkesimastix (Helkesimastigidae fam. n.) differs unexpectedly radically from cercomonads, lacking their complex microtubular ciliary roots, grouping not with them but with Sainouridae within Pansomonadida. Longitudinal cortical microtubules emanate from a dense apical centrosomal plate, where a striated rhizoplast attaches the nucleus, and two very short subparallel centrioles attach by dense fibres. The marginally more posterior centriole, attached to the centrosomal plate by a dense forked fibre, bears the long 9+2 gliding posterior cilium and a microtubular root; the left-side, nucleus-attached, left centriole bears an immotile ciliary stump with abnormal axoneme of nine disorganized mainly singlet microtubules, unlike the sainourid anterior papilla. Both transitional regions have a proximal lattice, the posterior centriole with slender hub. Sainouroidea superfam. n. (Sainouridae; Helkesimastigidae) have homologous cytoskeletal geometry. Dorsal Golgi dictyosome and posterior microbody are attached to the nuclear envelope, which has slender micro-invaginations and probably a cortical lattice. Bacteria are digested posteriorly in association with numerous mitochondria with flat cristae.

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
