Abstract
Abstract Fi'bro.bac'ter. L. fem. n. fibra fiber or filament in plants or animals; N.L. masc. n. bacter rod or staff; N.L. masc n. Fibrobacter bacterial rod that subsists on fiber. Cells are rod‐shaped (0.3–0.5 µm × 0.8–1.6 µm) or ovoid (0.8–1.6 µm × 0.8–1.6 µm). Obligately anaerobic non‐sporing and not detectably motile by microscopy. They are able to migrate through agar when growing on cellulose, suggesting a gliding form of motility. Ferment a narrow range of carbohydrates including glucose, cellobiose, and cellulose. Other sugars including lactose or maltose are fermented by a few species. The fermentation products are acetate and succinate, and sometimes formate at low levels. Cells require CO 2 , straight‐chain and branched‐chain fatty acids in the media as well as ammonia as the N source. Membranes are composed of straight‐chain fatty acids, and phospholipids are predominantly ethanolamine plasmalogens. Habitat is the mammalian gastrointestinal tract. DNA G + C content ( mol %): 45–51. Type species : Fibrobacter succinogenes Montgomery, Flesher and Stahl 1988, 434 VP . Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Fibrobacter is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Pseudomonadati / Fibrobacterota / Fibrobacteria / Fibrobacterales / Fibrobacteraceae / Fibrobacter The genus Fibrobacter can also be recovered in the Genome Taxonomy Database (GTDB) as g__Fibrobacter (version v220) ** . GTDB classification: d__Bacteria / p__Fibrobacterota / c__Fibrobacteria / o__Fibrobacterales / f__Fibrobacteraceae / g__Fibrobacter * Meier‐Kolthoff et al. ( 2022 ).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
