Abstract
Introduction: Composition, petrologic type, and terrestrial weathering have all been identified as potential factors that may result in acoustic velocity variations in meteorites [1]. Particularly large velocity variations have been observed in genomict meteorites typically composed of breccias with light coloured angular fragments in a dark coloured matrix. The light and dark regions of these meteorites are compositionally the same, thus the velocity difference has been attributed to a variation in the petrologic type between the fragments and matrix. This project tests the hypothesis that different pore geometries associated with petrologic type in meteorites and fracture distributions affect the compressional and shear wave velocities, and thus the elastic properties of the rock. Significant porosities have been reported in the literature for ordinary chondrites [2] and anomalously low acoustic velocities in chondrites have been attributed to the presence of micro-fractures [3]; however the relationship between pore characteristics and sonic velocity in meteorites has never been explored.

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
