Abstract
Fig. 1. The Devonian actinopterygian Cheirolepis canadensis Whiteaves, 1881 from Miguasha, Canada. A. MHNM 05-132, general view of the right side of the caudal fin (A1), showing the dorsal fulcra (detail in A2) and the numerous ventral segmented and ramified lepidotrichia and the basal fringing fulcra (detail in A3). The double-arrows indicate the caudal fin fragments (I–V), sectioned in the planes indicated by the doted lines to obtain ground sections of fulcra and lepidotrichia (I), transversal sections of fulcra and scales and longitudinal sections of the basal segment of lepidotrichia (II), longitudinal sections of the lepidotrichia (III), transversal sections of lepidotrichia and fulcra (IV), and the very distal part of lepidotrichia (V). Dorsal fulcra of the dorsal margin of the caudal fin (A2). Basal fringing fulcra and segments of lepidotrichia (A3). B. MHNM 05-142, fossilised skin showing the scales organised in parallel rows. The double-arrows indicate fragments (VI–VIII), sectioned in the planes indicated by the doted lines to obtain ground sections of scales: tangential (VI), longitudinal (VII), transversal (VIII).
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.
