Abstract
CONTEXT: Here we present a case of Amanita smithiana poisoning resulting in acute kidney injury requiring dialysis, and highlight laboratory methods used to confirm the diagnosis. Identification of Amanita smithiana toxin using thin-layer chromatography can provide greater diagnostic certainty than history and renal function tests alone. CASE DETAILS: A 63-year-old male presented to hospital with anuria and gastrointestinal symptoms, two days after consuming a soup of wild mushrooms he had picked. He was found to be in acute renal failure, requiring hemodialysis. After nine days of supportive treatment, he recovered renal function, and was discharged in good health 15 days post-ingestion. The patient provided a sample of leftover soup, and examination of cooked mushroom fragments by a mycologist provided preliminary identification of A. smithiana. Thin-layer chromatography revealed the presence of A. smithiana toxin in the soup, confirming this identification. DISCUSSION: A. smithiana is a nephrotoxic mushroom that can be easily mistaken for the edible and highly prized Pine mushroom (Tricholoma magnivelare). It causes initial gastrointestinal symptoms, followed by acute renal failure. Treatment includes dialysis and supportive care until the patient recovers renal function. The chemical structure of the A. smithiana toxin is unknown, but it can be identified as a characteristic spot on thin-layer chromatography.

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
