severity High

Where. EN docs/usermanuals/en/data/leakage.md:41-42 · TR docs/usermanuals/tr/data/leakage.md:41-42

English text. Exact match in val/test (any field that matters: prompt, chosen, response, etc.).

Turkish text. Val/test'te kesin eşleşme (önemli her alan: prompt, chosen, response vb.).

Which is correct. Neither: one simhash over the extracted payload; DPO 'chosen' not included; exact duplicates are simply Hamming 0.

Proposed correction (Turkish text for the -tr page). Her satırın çıkarılan metin yükünün (bkz. Veri Seti Denetimi) 64-bit simhash'i, Hamming eşiği (varsayılan 3) içinde val/test satırlarıyla karşılaştırılır; tam eşleşme Hamming 0'dır. chosen/rejected gibi alanlar karşılaştırmaya girmez.
