Abstract
Composite tissue transplantation has emerged as a viable alternative to prosthetics and complex reconstructive surgery. Thus far it is reserved for cases which cannot be effectively reconstructed and where it offers some benefits over prostheses. It has been used in the upper extremity with encouraging results and, most recently, in the face. This report outlines what is believed to be the first such use in the lower extremity. A normal lower limb in a 3-month-old ischiopagus twin who was not going to survive was transplanted to the appropriate pelvic position, revascularized, and reinnervated in an otherwise healthy sister. The limb survived and, because of the immune compatibility, did not require immune suppressive therapy. The return of muscle function in the transplanted limb is encouraging. The transplanted limb appears to be fully sensate. In addition to reinnervation, the limb is now spontaneously under the cortical control of the recipient.

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
