Abstract
Electromagnetic Calorimeter (ECal), a subdetector of Multipurpose Detector (MPD), is designed to identify electrons, photons, and neutral hadrons produced in high-energy heavy-ion collisions at nuclotron-based ion collider facility (NICA) and measure their energies and positions. A Shashlyk-type sampling calorimeter composed of lead plates as absorbers and plastic scintillators arranged alternately was selected for ECal. Chinese MPD consortium is responsible for the development of 768 ECal modules which is $$1/3$$ of the whole ECal detector. In this report, the mass production process of ECal modules and a performance test system designed for the mass production will be presented. The uniformity of the ECal modules achieved based on cosmic ray test will be discussed. Preliminary results demonstrate the produced ECal modules met the design requirements, indicating the quality control in mass production is effective. These modules were delivered to the Joint Institute for Nuclear Research (JINR) at Dubna in March 2023, and will soon be installed on MPD detector for further commissioning.

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
