Bibliographic record
Abstract
Aquamastigales Tedersoo & Esmaeilzadeh-Salestani ord. nov. Type family. Aquamastigaceae Tedersoo & Esmaeilzadeh-Salestani. Diagnosis. Distinguishable from other fungi based on a diagnostic nucleotide signature in SSU V 4 (positions 966–975 gatcaagagc in S. cerevisiae; no mismatch allowed). Forms a monophyletic, least inclusive clade in Aquamastigomycetes, covering sequences EUK 1102371, EUK 1107057, EUK 1124848, EUK 1138328, EUK 1102991, EUK 1124847, and EUK 0320721 (Fig. 1). Notes. Recognized based on eDNA sequences only. Currently includes Aquamastigaceae (fam. nov.) and potential family-level taxa represented by sequences EUK 1102371 (permafrost sample in Canada), EUK 1107057 (lake sediment sample in Sweden), EUK 1124848 (forest soil sample in Estonia), EUK 1138328 (wastewater sample in Estonia), and EUK 1102991 (lake sediment sample in Sweden).
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.
