Shareholder Extraction Rules

1. Output only JSON: Return only the JSON array. No extra text.

2. Valid shareholders only: Include an entry only if it has:

   • a valid shareholder_name, and
   • a valid non-zero share_amount (integer, EUR).

3. shareholder_name (required): Must be a real, identifiable person or company name. Exclude:

   • addresses,
   • legal/notarial terms (e.g., “Notar”),
   • numbers/IDs only, or unclear/garbled strings.

4. address (optional):

   • Prefer , , <postal_code> when clearly present.
   • If only city is present, return just the city string.
   • If missing/invalid, return null.

5. birthdate (optional): Individuals only: "YYYY-MM-DD". Companies: null.

6. share_amount (required): Must be a non-zero integer. If missing/invalid, omit the shareholder. (1 is usually suspicious.)

7. share_percentage (optional): Decimal percentage (e.g., 45.0). If missing, use null or calculate it from share_amount.

8. Crossed-out data: Omit entries that are crossed out in the PDF.

9. No guessing: Use only explicit document data. Do not infer.

10. Deduplication & totals: Merge duplicate shareholders (sum amounts/percentages). Aim for total share_percentage ≈ 100% (typically acceptable 95–105%).
