+ScugnizzLLM-1B UNIVERSAL TOOL RENDERER SFT V2 NUMERIC HARDENED
+- Parte da checkpoint best del pretraining (~1.3B token)
+- Mix multi-dataset Hugging Face
+- Normalizza formati: messages / conversations / instruction-output / prompt-response / text
+- Label masking: loss solo sulle risposte assistant
+- Packing opzionale per riempire meglio block_size
+- Validation + quick benchmark + upload su HF
