Abstract
High Volumes of Grain Moved Through MRS Locks Last Week.For the week ending December 28, 945,000 tons of grain moved southbound through the locks on the Mississippi River System (MRS).This weekly volume marked the largest this year and the largest since the week ending May 28, 2022, when 947,000 tons of grain moved through the locks (GTR table 10).Also, for the week ending December 28, 500,000 tons of corn moved through the locks-the largest weekly volume this year and the largest for the last week of the year since 2020, when 497,000 tons of corn moved through the locks.Last week's 410,000 tons of soybeans moving through the locks likewise marked the largest volume for the last week of the year since 2020, when 482,000 tons moved through the locks.Recent increases in export sales of corn and soybeans have been driving the rise in grain movements, despite tow and draft restrictions along the MRS (GTR table 14).Record cold temperatures are expected in the Ohio Valley and the Mississippi Valley in the next 2 weeks, which could affect barge movements along the MRS.Port of Duluth-Superior Completes 2024 Navigation Season.On December 28, Federal Biscay, a handysize bulk carrier, departed the Port of Duluth-Superior carrying durum wheat destined for North Africa.Federal Biscay's departure marks the end of the oceangoing navigation season for the Port of Duluth-Superior, as the St. Lawrence Seaway-which connects the Great Lakes to the Atlantic Oceanwill close on January 5.According to USDA's Federal Grain Inspection Service data (available on AgTransport), wheat exports from the Port of Duluth-Superior were 444,000 metric tons in 2024.Although this figure is up 21 percent from the prior-3-year average, it is still down significantly from historic levels.As recently as 2010, the Port of Duluth-Superior exported nearly 1.9 million metric tons of wheat.Canada Determines Maximum Grain Revenue Entitlements for CN and CPKC.On December 24, the Canadian Transportation Agency (CTA) issued its annual maximum revenue entitlements (MRE) determination for western

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
