Bibliographic record
Abstract
Pteraster personatus Sladen, 1891 Reports for the Azores: Pteraster reductus Koehler 1907 a— $ Koehler 1909: 96–97, pl. 3, figs. 8–9, pl. 20, fig. 10; Mortensen 1927a: 102; Grieg 1932: 28–29, pl. 5, figs. 6–7; Cherbonnier & Sibuet 1972: 380; Gage et al. 1983: 282; Pteraster personatus Sladen, 1891 — Downey 1973: 76–77, pl. 32, figs. C–D; A.M. Clark & Downey 1992: 334, pl. 82, figs. A–B; García-Diez et al. 2005: 48; Benavides-Serrato et al. 2011: 187; Dilman 2014: 36. Type locality: Porcupine Seabight, SW of Ireland (51°01’N, 11°50’W). See: Downey (1973); A.M. Clark & Downey (1992); Benavides-Serrato et al. (2011). Occurrence: North Atlantic, in the west reported from Labrador (Cherbonnier & Sibuet 1972) and the Gulf of Mexico (Downey 1973), in the east recorded from the Rockall Trough (Cherbonnier & Sibuet 1972) and SW of Ireland (Sladen 1881) to? Mauritania (A.M. Clark & Downey 1992), including the Azores (Koehler 1909). Depth: 480– 2,870 m (Dilman 2014); AZO: 1,846 –2,870 m (Koehler 1909). Habitat: soft substrates, mud to muddy sand (Koehler 1909). Remarks: Koehler (1909) described a new species Pteraster reductus based on small poorly preserved specimens collected by Princesse Alice at several stations located within the Azores waters. Later, Downey (1973) argued that P. reductus represents juveniles of P. personatus dismissing the diagnosing differences selected by Koehler as size-dependent. No other material is known from the archipelago.

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.
