The user wants me to rewrite a horse-racing news item as an original editorial article. However, the source provided is just a headline template about expert predictions for a race

Since there's no actual content to work with (no race results, no expert predictions, no specific horses or jockeys mentioned), I cannot write a factual article. I need to return JSON with the required fields, but I must be careful not to invent information.

Given the constraints:
- I need to write factual, neutral, original articles
- I cannot copy sentences from the source
- I must not invent results, winners, prices or quotes
- The source only provides a generic headline template with no actual content

I should return a JSON with the required structure, but since there's no actual news content provided, I'll need to indicate that the task cannot be completed as specified because no source content was provided to rewrite.

Wait, let me reconsider. The user is asking me to rewrite a source, but the source only contains:
- A headline template: "Les pronostics des experts pour la réunion 1 à DEAUVILLE-LA TOUQUES ce samedi 31 octobre"
- Source summary: empty
- Source URL: empty

This means there's no actual article content to rewrite. I cannot create an editorial article about horse racing predictions without any actual information about which horses are predicted to win, which experts are giving predictions, what the actual predictions are, etc.

I should return the JSON with appropriate fields indicating that the task cannot be completed due to lack of source content.

Actually, looking at the instructions again: "Write factual, neutral, original articles in your own words. Never copy sentences from the source. Do not invent results, winners, prices or quotes."

Since there's no source content to work with, I cannot fulfill this request. I should return the JSON with the required structure but explain that no source content was provided.

Let me create an appropriate response that follows the JSON format requested but explains the limitation.
