Abstract
Ice crushing experiments similar to Gagnon and Daley (2005) have been repeated at twice the former high-speed video rate (1000 images/s) and with the intention of eliminating in-plane fractures that occurred in all previous tests. Rectangular thick sections (1 cm thickness) of lab-grown monocrystalline ice were confined between two thick Plexiglas plates and crushed at -10°C from one edge face at a rate of 1 cm/s using a transparent Plexiglas platen (1 cm thickness) inserted between the plates. Visual data were recorded from the side using the high-speed video and vertically through the platen using regular video. It was concluded that the system was too compliant to prevent the in-plane fractures, however, one test did show near full-thickness intact ice. From this test unambiguous pressure measurements were obtained for the intact and pulverized ice at the ice/platen interface utilizing the system's novel pressure sensor. As in the previous report, the production and flow of liquid in a thin layer at the intact ice/platen interface was evident. The apparatus was then modified significantly to reduce its compliance and more tests were conducted with the eventual desired result that in-plane fractures in the ice were eliminated. This confirmed that the apparatus is capable of yielding visual data of a 2-D slice of ice during crushing as though it was part of a larger piece of ice.

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
