New route could derail US Keystone XL pipeline
Bibliographic record
Abstract
Significance The Keystone XL extension is a major new proposed oil pipeline project, with implications for US-Canada trade (at a time of uncertainty surrounding NAFTA negotiations), Canadian oil producers, and the global oil market. Its prospects suffered a blow in November when Nebraska state regulators rejected the pipeline builder TransCanada’s preferred route, opting instead for a lengthier path through the state. Impacts Nebraska’s economy could lose out on millions of dollars in revenue if Keystone XL does not go ahead. US President Donald Trump could be hurt politically if a project that he so publicly backed falls through. Canadian Prime Minister Justin Trudeau faces provincial and local opposition to new pipeline projects.

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.
