Abstract
FIG. 4. — Agraulos ceticephalus (Barrande, 1846): A, internal cast of a cranidium attached to the thorax with preserved exoskeleton (NFM F-3476 from 5.97 m); B, internal cast of a cranidium attached to the thorax, partly covered with sediment, eye ridges and glabellar furrows slightly visible (NFM F-3951 from 7.10 m); C, internal cast of a cranidium attached to the thorax with preserved exoskeleton, eye ridges present (NFM F-3957 from 3.30 m); D, internal cast of a cephalon attached to the thorax, librigena attached, eye ridges present (NFM F-3621 from 9.08 m); E, mould of a cranidium attached to the thorax, spines on axial rings present, coarse ornamentation on thorax visible (NFM F-3476 from 5.98 m); F, mould of a cranidium attached to the thorax, occipital spine preserved (sedimentary filling laying in glabellar mould), coarse ornamentation on thorax visible (NFM F-3946 from 4.27 m); G, internal cast of a cranidium attached to the thorax, projection of axial spine preserved (NFM F-3831 from 7.43 m); H, internal cast of a cranidium attached to the thorax, eye ridges present (NFM F-2787 from 7.56 m); I, internal cast of a cranidium attached to first thoracic segments, eye ridges and glabellar furrows preserved (NFM F-3778 from 5.96 m). Scale bars: 1 mm.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
