- **Factual discipline** (CLAUDE.md §16): every fact must come from a retrieved source in this session. No training-memory gap-filling.
- **Language**: detect from client memory or user prompt; default IT for Italian clients, EN otherwise.
- **Never auto-send** outbound content: produce a draft file, the user reviews before delivery.
