Season overview

Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Scorpion" Season 4.
Keys: overview (160-220 word summary), primer (array of exactly 4 concise bullet points).
Constraints: Use ONLY provided synopsis and sources. No invented facts. No markdown/asterisks/headings/bullets in the text (though primer is an array). Output valid JSON only.
Input Sources:
[1] TMDB: Season 4 continues the saga across 22 episodes.
[2] IMDb: Created by Nick Santora. Stars Elyes Gabel, Katharine McPhee, Eddie Kaye Thomas, Jadyn Wong. Team of super-geniuses tasked with being the last line of defense against threats to National Security.
[3] TMDB Cast/Crew: Walter O'Brien (eccentric genius), Toby Curtis (behaviorist), Happy Quinn (mechanical prodigy). Homeland Security's new think tank.
[4] Wikipedia: Created by Nick Santora for CBS. Stars Elyes Gabel (Walter O'Brien), Katharine McPhee (Paige Dineen), Eddie Kaye Thomas (Tobias Curtis), Jadyn Wong (Happy Quinn), Ari Stidham (Sylvester "Sly" Dodd), Robert Patrick (Cabe Gallo).
[5] Variety: Irrelevant (about Spider-Man animated show).
Overview: The provided synopsis for Season 4 is extremely brief: "Scorpion Season 4 continues the overarching saga across 22 episodes." There is no narrative arc described in the sources for Season 4.
Constraint Check: I must write a 160-220 word summary. However, the sources only say it continues the saga across 22 episodes. If I write 160-220 words based only on the provided text, I will be inventing information, which is strictly forbidden.
Wait: The prompt says "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
Problem: If the source only provides one sentence about Season 4, I cannot meet the word count requirement without violating the "do not invent" rule.
Re-evaluating: Let's look at the general series info provided to see if I can construct a summary of the series context that applies to the season, but the prompt asks for "this season's narrative arc."
Source Analysis:
Season 4 length: 22 episodes.
Series premise: Walter O'
