I cannot write this article because no source content was provided. The 'Source summary' field is empty and no article text was communicated.

Since there's no actual source content to work with, I cannot write an original article based on information that doesn't exist. I should point this out to the user and ask them to provide the actual source content they want me to rewrite.

Wait, let me reconsider. The instruction says "Rewrite the following horse-racing news item as an original editorial article." But no actual news item content is provided. The "Original headline" is given but that's just a title, not the article body.

I need to respond appropriately - I cannot fabricate content based on an empty source. I should inform the user that no source content was provided.

Please provide the source content to rewrite so that I can produce an original editorial article in French about horse racing.
