Abstract
veltime analysis. This experimental model represents a HTI layer. We apply amplitude inversion of small incident angle data to extract the fracture orientation (direction of isotropic plane of the medium), and are able estimate the fracture orientation quite accurately. Knowing the fracture orientation, we modified the available linear PP reflection coefficient approximation to invert for the anisotropy parameters (ε(V), δ(V), γ). The results for all three anisotropy parameters from AVAZ inversion compare very favorably to those obtained previously by a traveltime inversion. This result makes it possible to compute the shear-wave splitting parameter, directly related to fracture intensity, which historically had been determined from shear-wave data, from a quantitative analysis of the PP reflected data.

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
