Abstract
steadily over the years. Arguably the current interest in Canada can be dated to the very visible fall of the St-Robert meteorite shower near Montreal, on 14 June 1994. At any rate, I have fielded numerous enquiries in Q1-2012 alone. Since St-Robert, there have been about 20 more falls and reported finds in Canada, including the well-publicised falls of Tagish Lake (2000), Buzzard Coulee (2008) and Grimsby (2009). Meteorite finds reveal some interesting traits of human psychology. There is nothing odd about finding an unusual object and wondering what it is- for some years I was a rock-aware child who thought that he had a meteorite (hematite nodule!). But let’s recall that there are only about 75 meteorites identified Canada-wide (most of them listed at:

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.
