Abstract
In the mid-1990s, amid concerns and realities surrounding the shift to large industrial-style swine confinement production units in Iowa, an alternative swine production system was introduced to the Midwest from Canada−hoop structures or hoops. Hoops are large tentlike structures that are deep bedded with cornstalks or straw. The pigs are kept in the hoop usually as one large group (>150 head). The hoop is naturally ventilated. Bedding is added as the pigs grow. The hoop is cleaned after the pigs are marketed. Typical size for hoops is 30 ft × 84 ft for 200 market pigs. Wider hoops with steel truss arches are now on the market. Wider and longer hoops often have ridge vents to improve ventilation. Several companies are now marketing small-scale hoops of widths less than 20 ft These are often called utility shelters. The objective of this project was to demonstrate a small-scale hoop structure for swine. Low cost, small scale, versatility and quasitemporary status were emphasized.

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.
