Abstract
Abstract Two-dimensional and three-dimensional electrical resistivity imaging (ERI) surveys were conducted on the southern part of Saturna Island, British Columbia, and interpreted using a lithology- and structure-based hydrogeological conceptual model. Highly resistive sections of the images are interpreted as lightly fractured sandstone units of the Protection Formation. More conductive regions of the images are interpreted as the mudstones of the Cedar District Formation. The two-dimensional (2-D) cross sections contain sub-vertical zones of decreased resistivity that cut across the sub-horizontal formations. The three-dimensional (3-D) image displays a resistive formation on the western side of the image that is separated from a more conductive region by a sub-vertical contact. The sub-vertical contact in the 3-D image and the sub-vertical low resitivity zones in the 2-D images are aligned, and the low resistivity zones are interpreted as the intensely fractured Harris Fault zone. By interpreting the 2-D and 3-D ERI results using a hydrogeological conceptual model, and verifying the results against outcrop observations and previously-collected borehole video and geophysical data, the aquifer architecture can be accurately constrained at a sub-regional scale.

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
