Abstract
Small spot size laser testing for single-event effects has proven to be a particularly productive path to insights on the physics of charge collection and circuit response that are difficult or impossible to obtain through broad ion beam tests. As a result, there are a number of such laser facilities; for example, four of them were compared in 2012 [1], but a relatively new facility at the facility at the University of Saskatchewan offers a unique galvo-mirror, laser-spot scanning capability in addition to the usual micrometer-based DUT motion stage [2]. Operating in a fashion similar to LASIX eye surgery, fast pin-point redirection of the laser beam makes tractable (seconds, not hours or days) comprehensive scanning of a millimeter size field-of-view. Combined with auto-stepping the field-of-view, this new spot scanning capability opens up the possibility of comprehensively covering a large die and finding all SEE sites, including the rare, but important, ones such as SEFIs.

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
