Bibliographic record
Abstract
Fig. 7. Histology of dermal denticles of Listracanthus pectenatus sp. nov., Lower Triassic, Wapiti Lake, British Columbia. A. Horizontal cross−section (perpendicular to long axis) of specimen UALVP 1889 (section T1). Note the secondarily "remodelled" central areas between the lateral ridges. B. Vertical sections along plane and long axis of a large denticle of specimen UALVP 38562 (sections T1 and T2). Note the large, well−defined cavities in the bases of the denticles in B1, B2 and the solid processes of the posterior border in B3. B4, B5. Vertical cross−sections (as above) of specimen UALVP 38562 (section T4 [B4] and section T6 [B5]) show that the bases of the comb−like processes in the posterior border are only in part secondarily ossified, complex structures with small lateral processes. All arrows point posteriad.

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.
