The synopsis for S17E16 is very short: "While investigating the suicide of a retired Navy officer who left a rare, valuable - and possibly stolen - coin to the National Museum of the Navy, the team imagines themselves in his life story in order to piece together how the coin ended up in his possession."
The sources provide general series information (creators, premise, general cast) but no specific character names or plot details for Season 17, Episode 16.
Problem: The word count requirement is 280-380 words. The provided synopsis is only about 45 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." AND "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
If I strictly follow the "only verifiable facts" and "do not invent" rules, I cannot reach 280 words without repeating myself or adding fluff, which violates the "neutral, encyclopedic prose" and
