Abstract
Canadian bitumen is too viscous to transport by rail and pipeline to markets. One approach to solve this viscosity issue is to dilute the bitumen with a thinning agent to meet transport specifications, but the addition of diluent underutilizes pipeline capacity and increases production cost. A second approach involves the partial refinement of bitumen to produce synthetic crude, which better utilizes pipeline capacity; however, capital and operational costs are high. A third alternative is a new technology that involves wrapping bitumen in a polymer layer to form a solid "puck" termed Canapux, but transportation of this product to coastal ports is limited to rail. Also, greenhouse gas emissions are greater when oil is transported by rail rather than pipeline. In the end, a variety of bitumen products will be transported in Canada, but not all of these products will respond to remediation equally when spilled. In order to ensure effective spill contingency planning, we recommend that engineered bitumen products have physical properties that are resilient to change, within the range of typical response times, after a spill.

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
