+## 📚 Training Data
+
+The model was trained on a proprietary **Golden Dataset of 27,671 financial filings**, manually curated to represent the diverse landscape of global corporate reporting.
+
+* **Source:** Real-world filings from listed companies across **Europe (primary focus)**, North America, and Asia.
+* **Multilingual:** Includes documents in English, French, German, and other major European languages (leveraging the multilingual capabilities of Jina-V3).
+* **Diversity:** The dataset preserves the natural "long-tail" distribution of financial data, ranging from massive 500+ page **Annual Reports** to single-page **Press Releases** and complex **ESG Disclosures**.
+* **Quality Control:** Mapped to a strict 2-level hierarchy to resolve semantic ambiguities common in regulatory filings (e.g., distinguishing a *Share Buyback* announcement from a *Director's Dealing* notification).
