Abstract
Abstract A test program, undertaken as part of a C-CORE led Joint Industry Program(JIP), was carried out to investigate the limiting strength and failuremechanisms of seabed gouging ice ridge keels. A test frame was designed, fabricated, commissioned and used in the test program. During tests, methodswere developed to build & test large size keel specimens, and surfaceprofile both keel and soil bed before and after test. Testing consisted ofloading the keel with a surcharge force and initiating a horizontal movement ofsoil bed until keel failure was observed. In total, nine keels weremanufactured and tested under a variety of initial confinement pressuresranging from 0 kPa to 75 kPa. Six tests were conducted with a gravel berm andsoil bed and three tests were conducted using a steel (rigid) berm face andgravel soil bed. A summary of the test results and key observations arepresented in this paper.

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
