Abstract
The occurrence of Atmospheric chloride-Induced Stress Corrosion Cracking (AISCC) in austenitic stainless steels beneath ‘wetted’ deposits of either artificial sea-salt, organically-enriched artificial sea-salt or MgCl 2 .6H 2 O has been investigated under controlled climatic conditions (40°C and 33% Relative Humidity). The presence of organic exudate in relatively large artificial sea-salt deposits (~3 mm diameter) appears to markedly decrease the induction time associated with AISCC; cracking occurred within a week in one U-bend specimen, well inside the ~12 week period usually observed under ‘wetted’ deposits of artificial sea-salt alone. Cracks appear to initiate from crevices formed under NaCl crystals. It is tentatively proposed that the organic species promotes greater coverage by the MgCl 2 electrolyte in the vicinity of these crystals. This increases the probability of crevice initiation, and allows more rapid production of localized corrosion sites (pits or crevices) propagating under conditions that allow the transition to AISCC (pit/crevice dissolution rate < crack velocity).

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
