Abstract
Corrosion of a pipe surface in a channel crevice has been modeled assuming oxygen diffusion through a holiday in a permeable coating. The crevice was thin and narrow with a finite length. The crevice solution pH was 9.2 controlled by ferrous hydroxide (Fe[OH]2) precipitate, external oxygen pressure was 0.21 atm, the crevice gap between the coating and the pipe surface was 0.5 mm, and the coating thickness was 0.05 mm. Without imposed cathodic protection (CP), an oxygen concentration cell formed inside the crevice. The effect of this cell was that the pipe surface was less anodically polarized near the holiday and more anodically polarized away from the holiday. This internal polarization (IP) resulted in less corrosion near the holiday and a broad extension of corrosion within the crevice. Imposed CP weakened the effect of IP and decreased corrosion at the pipe surface because it consumed oxygen. Oxygen diffusion through the coating weakened the effect of IP and increased corrosion in the crevice. The greater the solution resistance and the smaller the total crevice length, the weaker the IP and the greater the corrosion current near the holiday.

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
