Abstract
This article presents the results of three ice impacts against a stiffened panel cut from the recently decommissioned ex-HMCS IROQUOIS. The upgraded experimental apparatus (the large double-pendulum), its sensors, and experimental conditions are also presented. The apparatus consists of two pendulums, one constrains and supports an ice feature, and the other constrains and supports a ship hull grillage structure. The first ice impact had data integrity and ice cone geometry issues, and so is treated as a commissioning test. During the second impact the impact force peaked at 553.9 kN, the total impact duration was 0.055 s and the hull plating acceleration at the centre of the impacted location was a maximum of 10877 m/s2. The third impact exhibited a peak force of 773.6 kN, 9691 m/s2 of acceleration, and had an impact duration of 0.039 s.

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
