Abstract
Kidney tumours form a broad spectrum of distinguished histopathological and molecular genetic entities. The last WHO classification is dated to 2004. Current classification has been published in October 2013 by ISUP (International Society of Urological Pathology). There were 5 new epithelials tumours: tubulocystic renal cell carcinoma (RCC), acquired cystic disease-associated RCC, clear cell (tubulo-)papillary RCC, the MiT family translocation RCCs (in particular t(6;11) RCC), and hereditary leiomyomatosis RCC syndrome-associated RCC. Another 3 subtypes of RCC were added as "provisional" entities: thyroid-like follicular RCC; succinate dehydrogenase B deficiency-associated RCC; and ALK translocation RCC. Modifications were performed in already existing entities: multicystic clear cell RCC (formerly multilocular cystic RCC) is newly included as a subcategory of clear cell RCC with low malignant potential. Oncocytic papillary RCC (PRCC) has not been recognized as a distinctive subcategory of PRCC yet. Hybrid oncocytic-chromophobe tumour was placed within the chromophobe RCC category. Recent advances related to collecting duct carcinoma, renal medullary carcinoma, and mucinous spindle cell and tubular RCC were elucidated. Outside of the epithelial category, current approach to our understanding of angiomyolipoma, including the epithelioid variant and angiomyolipoma with epithelial cysts was clarified. Cystic nephroma and mixed epithelial and stromal tumour were considered as a spectrum of one entity. Synovial sarcoma was placed within the sarcoma group. The new classification is to be referred to as the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
