Abstract
Abstract Experimental data on the decompression wave speed of a conventional gas mixture and three other rich gas mixtures with varying C1 from 70 to 82% have been collected. An NPS 2 stainless steel expansion tube test rig has been constructed at TCPL Gas Dynamic Test Facility (GDTF) in Didsbury, AB, Canada, specifically for this task. Decompression wave was generated by a rupture disc at the end of the tube, which was instrumented with eight high frequency response pressure transducers located along the tube. The facility has the following three distinct capabilities: high initial pressures of up to 22 MPa, low initial temperature down to ‐20°C, and flexibility in testing any rich gas mixtures. The decompression wave speed data are presented in terms of the decompression expansion pressure ratio for all four gas mixtures and three initial line pressure of ∼ 10, 14 and 20 MPa. Comparison between experimentally obtained decompression wave speeds and those predicted by GASDECOM is also made for each test.

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
