The synopsis is extremely sparse. It only contains about 40 words of plot information.
The prompt asks for a 280-380 word recap.
Constraint Conflict: I am instructed to "Use only supplied facts" and "If the synopsis is sparse, stay concise rather than guessing."
If I strictly follow "Use only supplied facts" and "Never add... plot events not explicitly present," I cannot reach 280 words without repeating myself or adding fluff, which violates "original, neutral, encyclopedic prose."
However, the prompt also says "Write a grounded 280-380 word episode recap."
Let's look at the available facts again.
