Abstract
A high-throughput, general purpose robotic system has been developed which transports flash-cooled crystals securely and safely, automatically mounts crystals on most goniometers, optically centers them in the x-ray beam, screens for diffraction quality, collects and processes diffraction images, recovers the crystals and stores them in a liquid nitrogen dewar. The system is a refinement of the proven actor system from abbott laboratories [1]. Magnetic crystal storage and transport magazines are designed to hold up to 60 crystals in a standard dry shipper with easy access to any of the positions. The system is based on a general purpose 5-axis programmable robot that allows the system to be used in an infinite number of configurations including horizontal, vertical or virtually any other goniometer axis orientation. The unique non-magnetic end-effector securely grips standard hampton pins and places them on a glide goniometer magnet without the need to move cryosystream nozzles or beam stops. The glide goniometer translates the crystal 3 mm in all directions in as little as 2 micron increments for centering. All operations are controlled by director, a software tool which totally automates the high-throughput process of selection, centering, screening, collection and retrieval of crystals. The entire procedure has been optimized for high-throughput crystallography at synchrotron beamlines and in the home lab.

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
