Abstract
Abstract S. varia is a perennial herbaceous vine from the pea family that has been introduced into various countries as an ornamental, for erosion control, ground cover, soil improvement, as a cover crop and as fodder/forage for livestock (GISD, 2016, US Forest Service, 2016). The species is considered a threat in the USA, for its rapid vegetative growth resulting in monocultures and its detrimental effect on the native vegetation (Molano-Flores, 2014; Invasive Plant Atlas of the United States, 2016). The multi-branched rhizomes can extend up to 3 m long; and the stems can extend up to 2 m long; plants can fully cover 20-30 square metres in four years (Molano-Flores, 2014; US Forest Service, 2016). Luneva (2009) cites it as a dangerous weed that is a problem in rye, oat, summer and winter wheat crops and in vineyards; seeds littering the cereal grains, being hard to separate. There are no invasive behaviour reports for the species in western Europe (Alien Plants of Belgium, 2016). It is reported as invasive in many states of the USA, and in British Columbia in Canada (Molano-Flores, 2014; Casals, 2016; E-Flora of British Columbia, 2016; US Forest Service, 2016). It is included in a list of noxious plants of concern in Mexico, with the recommendation of doing a country assessment for its eradication or containment (Sánchez-Blanco et al., 2012). It is also included in the Global Invasive Species Database of the IUCN (GISD, 2016). An invasiveness assessment carried out for Alaska gave it an invasiveness rank of 68 on a scale of 1-100 (Alaska Natural Heritage Program, 2016).

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.
