Abstract
Surirella terryi var. arctica has been described more than 50 years ago from northern Alaska. Since then, it has not been reported in the scientific literature except for a single record. We studied in detail the holotype slide and material of S. terryi var. arctica and several other samples from northern Alaska, and concluded that S. terryi var. arctica differs from the nominate variety and should be placed in a separate species. Surirella arctica comb. et stat. nov. is presented here including a detailed morphological description and light and scanning electron micrographs. Surirella arctica can be easily recognized due to the internally thickened median area and transverse costae, together forming a craticula-like structure on the interior valve surface. This feature is well visible in the light microscope and helps discriminating S. arctica from other Surirella species similar in valve shape, size and other morphological characters. These taxa include S. angusta, S. heardensis and an unknown species from Siberia and Mongolia. The presence of S. arctica has been confirmed to date only from the northern Alaska and likely from the high Arctic in Canada.

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
