Abstract
Detecting the surface shape or pressure distribution of a tactile sensor made of a homogeneous and elastic material, given internal stresses or strains, is an ill-posed problem. The difficulties are further compounded by introduction of inhomogeneities into the sensor material in order to perform the transduction, which significantly change the sensor's mechanical behaviour. In order to investigate the numerical stability of curvature detection, we discretized a linear elastic half-space. Using closed-form solutions of surface pressures for rigid indentors, a regularized solution can be formulated. From finite-element models of inhomogeneous 3D tactile sensors, subsurface strains can be estimated in a physically realistic fashion. Using these as input to the regularized solution, we have found that it is not possible to reliably deduce the difference between contacting the sensor's surface with various axisymmetric objects.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
