Season overview

Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Ancient Aliens" Season 5.
Keys: overview (160-220 words), primer (array of exactly 4 concise bullet points).
Constraints: Use ONLY provided synopsis and sources. No invented facts. No markdown. No asterisks. No headings. No bullet points in the text (though the primer is an array). Output valid JSON only.
Word count constraint for overview: 160-220 words.
Synopsis: "ANCIENT ALIENS Season 5 continues to explore the fascinating field of alien research. From cave paintings to firsthand accounts, this inquiry provides grounded historical depth."
Source [1]: "Did intelligent beings from outer space visit Earth thousands of years ago?"
Source [2]: Ratings/Platforms (not relevant for narrative).
Source [3]: Start date 2009.03.08 (not relevant for Season 5 specific content).
Source [4]: Wikidata link (no content provided).
Overview: The provided synopsis is extremely short: "ANCIENT ALIENS Season 5 continues to explore the fascinating field of alien research. From cave paintings to firsthand accounts, this inquiry provides grounded historical depth."
Problem: The user asks for a 160-220 word summary. The provided text is only 27 words.
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Dilemma: I cannot meet the 160-220 word count requirement without inventing information, which is strictly forbidden by the primary instruction.
Decision: I must prioritize the "ONLY verifiable facts" and "never invent" instructions over the word count instruction. However, if I write a 27-word summary, it fails the word count. But if I write a 160-word summary, I am violating the "never invent" rule. In professional prompt engineering/instruction following, the "do not invent" rule is a hard constraint on truthfulness, whereas word count is a stylistic constraint. I will provide the summary based only on the text provided.
Wait, looking at the prompt again: "factual 160-220 word summary". If the source material is insufficient to reach that length, I cannot fulfill the request as written without violating the core instruction.
