The synopsis is very brief.
The word count requirement is 280-380 words.
Problem: The provided synopsis only contains about 50 words of actual plot information.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." AND "Write a grounded 280-380 word episode recap."
Conflict: I cannot reach 280 words without inventing details, which is strictly forbidden by the prompt ("You never invent or guess... If a detail is not in the provided material, you omit it rather than guess.").
Resolution: I must follow the instruction to "only use supplied facts" and "never invent or guess." If the facts provided do not allow for a 280-word recap without violating the "no guessing" rule, I must prioritize the "no guessing/only supplied facts" rule. However, usually, in these prompts, the user expects the output to meet the length. But as an archivist following strict instructions, I cannot hallucinate.
Wait: Let me re-read. "Write a grounded 280-380 word episode recap... Use only supplied facts."
If I write only the facts provided, the text will be:
