Abstract
At the Dalhousie Plastic Surgery Alumni Reunion at the Atlantic Plastic Surgery meeting in Halifax, Nova Scotia, in September 2001, 22 subjects, including 18 certified hand surgeons, were injected with 1.8 mL of 2% lidocaine with 1:100,000 adrenaline in three places in one finger of each hand. One hour later, the same sites of one hand were injected with phentolamine (1 mg in 1 mL), and the other hand was injected with saline. Subjects were blinded as to which hand received the phentolamine. It took an average of 85 min for the adrenaline-injected fingers to return to normal colour after phentolamine injection. It took an average of 320 min for the adrenaline-injected fingers to return to normal colour after saline injection (no phentolamine). We also observed that lidocaine with adrenaline provided an average of 549 min of anesthesia in nonphentolamine-injected fingers. Phentolamine consistently and reliably reversed adrenaline-induced vasoconstriction in the finger.

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
