Abstract
An official with the Canadian Air Transportation Security Authority (CATSA) explains Canada's approach to security at airports. Created after the events of Sept. 11, 2001, it is part of a comprehensive $1.8 billion package over five years. CATSA is a Crown corporation that reports to Parliament through the Minister of Transport and is run by an 11-member board, whose members include airline industry and airport operator representatives. It has six major areas of responsibility, pre-boarding passenger screening, explosive detection systems, contracting for in-flight policing, screening non-passengers entering the airport, and supplemental airport policing services. Describes three stages of security, predictive, proactive and reactive. A common metaphor for everyday activities is that of an onion, a series of layers, with each protecting the next one farther down until you arrive at the core. Among elements of the program are extensive training and testing of employees and data collection to improve efficiencies.

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.
