Abstract
FIGURES 171–178. Nitzschia semirobusta. SEM images. 171–173 Valve external view. 174–178 Valve internal view. 171–173 Same valve. (171) Valve and areolae shape, and raphe. (172) Central raphe ending, and areolae external occlusion. (173) Apex, terminal raphe ending, mantle without raphe areolae, and open band. Note 173 rotated 45 degrees. (174, 176) Valve showing fibulae, areolae, and portulae. 174, 178 Same valve. (175) Broken valve, showing fibulae, knob-like structures (white arrows), portulae, mantle and valve face areolae. 175, 177 Same valve. (177) Areolae occlusion in detail. Note 177 rotated 90 degrees. (178) Valve showing fibulae, areolae, central portulae, note raphe, areolae, and central nodule inside of portulae. Source: (171–173, 173, 177) Brazil, Piracaia, SP406271. (174, 176, 178).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
