Abstract
Poly( N ‐isopropylacrylamide) (pNIPAm) microgel‐based materials can be fabricated that self‐fold into three‐dimensional structures in response to changes in the environmental humidity. The materials are composed of a semi‐rigid polymer substrate coated with a thin layer of Au; the Au layer is subsequently coated with a pNIPAm‐based microgel layer and finally covered with a solution of polydiallyldimethylammonium chloride (pDADMAC). The pDADMAC layer contracts upon drying causing the material to deform (typically bending); this deformation is completely reversible over many cycles as the environmental humidity is systematically varied. Here, by varying the size and aspect ratio of the polymer substrate, it is possible to develop a set of empirical rules that can be applied to predict the material's self‐folding behavior. From these rules, materials that self‐fold from two‐dimensional, flat objects into discrete three‐dimensional structures, which are fully capable of unfolding and folding multiple times in response to humidity, are designed.

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
