Abstract
In spring 2004, an outbreak of highly pathogenic avian influenza (HPAI), subtype H7N3, occurred in the Fraser Valley of British Columbia, Canada. The active outbreak lasted more than 90 days; 42 commercial poultry farms were identified as infected premises, and more than 17 million birds were culled. Through the depopulation of HPAI-positive farms and the strategic depopulation of adjacent test-negative farms, a total of 410 commercial poultry farms were emptied. The goals for the commercial poultry industry were to expedite restocking, reduce nonproductive downtime, negotiate equitable financial compensation, review and restructure emergency disease response plans, and identify and implement mitigation strategies. After the outbreak, multijurisdictional reviews identified the strengths and weaknesses of the outbreak control strategy. Lessons learned were incorporated into current emergency disease response protocols for both industry and government. The industry-led challenge to initial compensation values, especially for specialty poultry and breeder birds, resulted in a review of the federal Health of Animals Act. The British Columbia poultry industry, in collaboration with the British Columbia Ministry of Agriculture and Lands, developed an Enhanced Biosecurity Initiative that included the identification of mandatory on-farm biosecurity standards for commercial producers, an educational biosecurity self-assessment guide, and provisions for a producer self-quarantine to be enacted upon the first suspicion of disease.

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 it
