Abstract
With demand currently strong and little clarity about when, or if, the idled operations in China will come back on stream, the expected production from Canada Fluorspar and Sepfluor could create the next pinch point for the market’s supply-demand balance. Sepfluor will serve a wide range of users via shipments of 5,000-8,000 tonnes until June next year, allowing consumers to gauge the consistency and quality of the material and to decide whether it can be accepted in their own production systems, according to Wagner. Unless there is a significant shift in demand, this makes the long-term effects of the Chinese environmental controls the major driver of the market’s supply-and-demand balance, and therefore of prices. Magnitude is considering “the restart of a third and final pot line of primary production capacity, if and when market conditions allow,” chief executive officer Robert Prusak has told Metal Bulletin.

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.
