Abstract
An algorithm for estimating the pose and twist of a rigid body using measurements made by a redundant number of on-board accelerometers is formulated. Redundancy helps reduce the effect of the accelerometer noise. This algorithm is based only on rigid-body kinematics because it is intended to be used for rigid bodies acted upon by forces and moments elusive to modeling. Procedures are developed to calculate the angular velocity and acceleration as well as the attitude of the body along with the velocity and position of the centroid of the pickup points, all in the body frame. It is shown that a small installation error can cause the integration results to become unstable. This instability is compensated for by means of a pose-measurement sensor.

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
