Abstract
We analyzed the use and sharing of a logistics package, a returnable container, often out of stock, between Canada Post and its large mailing customers. Standardizing and sharing logistical packaging should bring members of a supply chain tangible benefits from productivity and efficiency gains. We determined that inventory imbalance between supply locations and demand locations caused the problem. We found that different accounting methods gave very different results in calculating the benefits. We concluded that there is always a benefit for the mailer. For Canada Post to benefit, however, the container must be returned quickly. We used a minimum-cost-flow model to confirm that the company has enough containers to satisfy demand. With better planning and control of the inventory, Canada Post can prevent disequilibrium between supply and demand.

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
