Bibliographic record
Abstract
Rhabdochona catostomi Kayton, Kritsky & Tobias, 1979 Description (after Kayton et al. 1979). With characteristics of the genus. Body filiform, males smaller than females. Caudal end conical with terminal spike. Mouth with two bilateral rudimentary pseudolabia, two large bilateral amphids, outer circle of cephalic papillae (inner circle apparently absent). Prostom funnel-shaped, lacking basal teeth, its inner wall with 10 longitudinal cuticular ridges terminating in anterior teeth. Cuticle lines entire vestibule. Oesophagus with anterior muscular and wider posterior glandular regions. Deirids small, bifurcate, lying slightly anterior to mid-vestibule. Males: body 8.9–14.3 long, 0.173–0.211 maximum width. Prostom 0.022–0.034, vestibule 0.134–0.174, muscular oesophagus 0.336–0.372, and glandular oesophagus 3.5–4.8 long. Deirids 0.076–0.085, nerve ring 0.204–0.238, and excretory pore 0.484 from anterior end. Tail 0.336–0.392 long, curved ventrally. Caudal alae absent. Subventral caudal papillae variable in number, 8 or 9 pre-cloacal, and 5 post-cloacal pairs (Fig. 44 A). Left spicule 0.546–0.562 long, slender, with ventral groove, its tip with ventral barb, bifurcate. Right spicule 0.151– 0.154 long, with reflected distal barb (Fig. 44 B). Length ratio of right to left spicule 1:3.62 to 1:3.65. Females: body 15.3–16.7 long, 0.248–0.292 maximum width. Prostom 0.028–0.031, vestibule 0.154–0.176, muscular oesophagus 0.375–0.417, and glandular oesophagus 4.97–6.10 long. Deirids 0.090–0.097 and nerve ring 0.227–0.284 from anterior end [position of excretory pore not stated]. Tail 0.227–0.280 long, usually straight (Fig. 44 C). Vulva post-equatorial comprising a transverse slit surrounded by elevated labia. Mature eggs ellipsoidal, embryonated, “poles usually with complex elongate filaments”, measuring 0.031–0.036 x 0.020–0.024 (Fig. 44 D).

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.
