Abstract
Accsim is a synchrotron/storage-ring tracking and simulation program that was originally written to simulate charge-exchange injection and accumulation of an intense proton beam in a KAON factory accumulator ring. It has subsequently been developed and used for other injection studies and for applications such as the optimization of collimation systems. The code performs basic six-dimensional tracking of an ensemble of particles in a magnet lattice and incorporates models for various processes such as multiturn injection, phase-space painting, RF capture, space-charge effects, interactions with stripping foils and collimators, and tabulation of particle losses and beam form factors. After a brief review of Accsim's architecture and basic design, this paper gives an update on the current status of the code and describes the more recent additions that have been made.

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
