Abstract
We apply state of the art 3D transient electromagnetic simulation and inversion techniques to a single transmitter gradient array survey. Direct current (DC) gradient array surveys offer a simple way to map horizontal variations in subsurface conductivity but suffer from a lack of depth resolution. We demonstrate by numerical experiment that it is possible to recover useful depth information from gradient array surveys. This is achieved by inverting the early off-time transient voltage decay along with the DC data—data that is often already collected in the case of an induced polarization survey.

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
