Abstract
In line with the worldwide trend of moving towards performance-based codes, Canada and many other countries are planning to introduce performance/objective-based codes in the near future. A performance-based approach allows for flexibility in design that may lead to improved cost-effectiveness. The success of these code systems will depend, to a large extent, on the ability of the available computational tools, most of which rely on suitably-defined design fires, to adequately predict the impact of fires on buildings and their occupants. It has always been recognized that the specification of design fires, derived from appropriate design fire scenarios, is a possible source of uncertainty in conducting any fire safety engineering assessment. This uncertainty stems from the difficulty in accurately calculating the combustion process (heat release rate, production of smoke and other gaseous species) based on the type, quantity, and arrangement of combustibles, as well as the point of ignition and subsequent fire spread to adjacent combustibles. This literature review was carried out to determine the range of methods used to characterize design fires. The methods currently available were found to be largely empirical in nature and fairly unsophisticated. The two main quantities used to describe design fires were found to be the heat release rate (pre-flashover scenario) and temperature-time profiles (post-flashover). The most widely-used pre-flashover design fires are t2 fires, whereas a host of empirical correlations are available for post-flashover design fires.

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
