Abstract
The NFIRAOS Deformable Mirror Electronics (NDME) system is integral to the Narrow Field InfraRed Adaptive Optics System (NFIRAOS) of the Thirty Meter Telescope (TMT). Using two sets of deformable mirrors to correct wavefront aberrations, the NDME converts stroke commands from the NFIRAOS Real-Time Controller (NRTC) into precise actuator drive voltages. The NDME FPGA firmware enables real-time functionality, handling concurrent command processing with strict timing requirements. It incorporates low-latency SPI for DAC and ADC and custom 1G Ethernet interfaces. Benchmarking with the Xilinx Kria K26 FPGA demonstrates the firmware's efficiency in managing data transmission and processing latencies adhering to a critical 75-microsecond threshold. These results validate the firmware's efficiency, robustness, and reliability, which are crucial for the TMT project's success.

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
