Season overview

Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Who Killed Sara?" Season 3.
Constraint 1: Use ONLY provided SYNOPSIS and SOURCES.
Constraint 2: No invented/guessed details (titles, names, dates, etc.).
Constraint 3: Original, neutral, encyclopedic prose in plain text.
Constraint 4: No markdown, no asterisks, no headings, no bullet points in the text content.
Constraint 5: Output valid JSON only.
JSON Keys:
overview: 160-220 word summary of Season 3's narrative arc.
primer: Array of exactly 4 concise bullet points (though the prompt says "no bullet points" in the prose instructions, it asks for an "array of exactly 4 concise bullet points" in the JSON structure. In JSON, an array is the standard way to represent bullet points. I will provide an array of 4 strings).
Source [1]: "In this final season, as enemies become allies, Álex gets an answer to the question that has tormented him for years: What really happened to Sara?"
Source [2]: "Hell-bent on exacting revenge and proving he was framed for his sister's murder, Álex sets out to unearth much more than the crime's real culprit."
Source [3]: "Who Killed Sara? (2021~2022)... Season 3: 2022년 5월 18일".
Source [4]: Irrelevant (about "The Killing").
Goal: 160-220 words.
Available info: It is the final season. Enemies become allies. Álex seeks an answer to what happened to Sara. He was previously hell-bent on revenge and proving he was framed for his sister's murder. He wanted to find the real culprit and more.
Problem: The provided text is extremely sparse. I cannot reach 160-220 words without inventing details, which is strictly forbidden.
Constraint Check: "If a detail is not in the provided material, you omit it rather than guess."
Conflict: The prompt asks for a 160-220 word summary, but the source material only provides about 40-50 words of actual plot information.
Resolution: As an archivist following strict rules, I cannot fulfill the word count requirement if the source material does not contain enough information. However, I must try to expand
