The user wants me to rewrite a horse-racing news item as an original editorial article. However, the "source" provided is essentially empty - it only contains a garbled string that

There's no actual content to rewrite. The source summary is empty and the source URL is empty.

Since I cannot invent content or copy from a source (and there's no source content anyway), and I must write factual, neutral, original articles, I need to handle this situation appropriately.

Given the constraints:
1. I must write factual, neutral, original articles in my own words
2. Never copy sentences from the source
3. Do not invent results, winners, prices or quotes
4. Return JSON with specific keys
5. The source provided has no actual content to work with

I should return an error message or indicate that insufficient information was provided. However, looking at the instructions again, the user wants me to "Rewrite the following horse-racing news item" but there's no actual news item content provided.

Let me think about what to do here. The instructions say I should write factual articles, never invent content, and the source has no actual content. I cannot fabricate a news article about a race that has no provided details.

I think the appropriate response is to indicate that insufficient source material was provided to complete the task. However, I need to check if there's a way to interpret this differently.

Wait - let me re-read the request. The user says "Rewrite the following horse-racing news item" but the "Original headline" field contains what appears to be corrupted text. It looks like it should say something like "Prochain départ : 21:15 - SAN ISIDRO - R9C7 - PREMIO TELESCOPICO" (Next departure: 21:15 - SAN ISIDRO - R9C7 - PREMIO TELESCOPICO).

This is just a race listing, not a news article with content to rewrite.

Given that:
1. There's no actual article content provided
2. There's no source summary
3. There's no source URL
4. I cannot invent content
5. I must write factual, neutral, original articles

I'll provide a response indicating that the source material is insufficient to complete the task, as I cannot fabricate a news article from nothing.

Actually, let me reconsider. The user might expect me to work with what little information is there. But there's really nothing to work with - just a race listing with no context, no results, no story, nothing.

I'll return a clear error message in the requested JSON format, explaining that insufficient source material was provided.
