Abstract
Through the swiftness of air travel, severe acute res-piratory syndrome (SARS) rapidly migrated fromits origins in Guangdong Province, China, in No-vember 2002 to many corners of the world, including Canada in February 2003.1 This syndrome, characterized by fever, headache, myalgia, cough and shortness of breath, leads to pneumonia and occasionally to acute respiratory distress syndrome and death. There is strong evidence that SARS is caused by a novel coronavirus2–5 spread mainly through respiratory droplets. As of July 10, 2003, a total of 438 cases of SARS (250 probable and 188 suspect) were reported in Canada, 375 (85.6%) of which occurred in Ontario. The index case of SARS in Canada was an elderly woman who returned to Toronto on Feb. 23, 2003, after a visit to Hong Kong. She had been exposed to SARS during her stay at a hotel in Kowloon, where a cluster of 13 cases of SARS was subsequently reported.6 She became ill upon her return to Toronto, and the infection spread to family members, one of whom was later admitted to the emer-gency department of a local hospital, where a large nosoco-mial outbreak occurred. In this paper we describe the pre-liminary results of the epidemiological investigation of the initial 128 cases of SARS associated with this outbreak, in-cluding those who became infected in the hospital and the next generation of illness among their contacts. Methods Cases were classified as either probable or suspect SARS based on the case definition issued by Health Canada.7 Suspect cases were defined as people presenting with fever (temperature greater than 38°C) and 1 or more respiratory symptoms, including cough, shortness of breath or difficulty breathing. Suspect cases also had to have travelled, within 10 days before symptom onset, to a World Health Organization (WHO) reported affected area in Asia, to have visited a defined setting that was associated with a cluster of SARS cases or to have had close contact with a suspect or probable case. Probable cases were defined as people meeting the suspect case definition and having severe progressive respira-Investigation of a nosocomial outbreak of severe acute

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.
