Abstract
Lindane, one of 8 possible hexachlorocyclohexane isomers, is a white or yellowish crystalline powder with a persistent musty odor. It is a commercial insecticide mostly used on fruit and vegetable crops and against cotton insects. It is also used as a soil poison and as a toxicant for grasshoppers. It is used in Canada as a pesticide on canola crops to prevent seed rot. Its use in the U.S. is restricted under the Safe Drinking Water Act of 1974. It is also a persistent organic pollutant (POP); that is, a chemicals that does not degrade easily in the environment and can travel through air, rivers, and oceans to places far away from where it was originally released (e.g., to the Arctic). This chemical is lipophilic (it prefers to dissolve in fat rather than water) and can biomagnify in food chains and cause severe health effects in wildlife and humans (e.g., cancer). In the United States and in many other countries, it is used as a topical treatment for head and body lice and scabies, a contagious skin disease caused by mites. Gamma-HCH has not been produced in the United States since 1976 but it is imported as dust, powder or liquid and used as an insecticide. It is also found in lotions, creams, or shampoos to control scabies and head lice. Vapors of HCH may irritate eyes, nose and throat. In humans, the effects of breathing toxic amounts of gamma-HCH can result in blood disorders, dizziness, headaches, and possible changes in the levels of sex hormones in the blood.

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.
