Abstract
Abstract The new explosive loading experimental system of digital laser dynamic caustics was developed by replacing the conventional multi-spark point source light and the previous multi-frame film camera with the solid-state laser and the digital high-speed camera, respectively; namely, a new caustics experimental system of high-speed photography system using a combination of solid-state laser and digital high-speed camera was created. This new experimental system was used to conduct the crack propagation test of single-borehole explosion with defective medium and the double-boreholes explosive loading experiment to obtain the clear digital caustics photos. If compared with the conventional optical photos, these digital photos were found to be clearer with more reliable results and longer recording time, which demonstrates that the new system can meet the requirements of ultra-dynamic fracture problems such as blasting. The new optical system is simple, user-friendly, which ensures a low experimental cost, short cycle, and the continuous observation throughout the fracture process.

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
