Source Material Analysis:
TMDB Season Synopsis: "Supergirl Season 3 continues the overarching saga across 23 episodes."
Source [1]: Mentions Kara Zor-El (24 years old) was taken in by the Danv... (cut off).
Source [2/3]: Creators: Ali Adler, Greg Berlanti, Andrew Kreisberg. Cast: Melissa Benoist, Chyler Leigh, David Harewood, Katie McGrath.
Source [4]: Kara Zor-El (24) was taken in by the Danvers family when she was 13 after being sent away from Krypton.
Source [5]: American superhero drama developed by Ali Adler, Greg Berlanti, and Andrew Kreisberg.
Overview: The provided text for Season 3 is extremely limited: "Supergirl Season 3 continues the overarching saga across 23 episodes." The other sources provide general series info (Kara's age, her backstory, creators, cast), but they do not provide any specific plot details, narrative arcs, or character developments for Season 3.
Problem: The user asks for a 160-220 word summary of the season's narrative arc. However, the provided text contains zero information about the Season 3 narrative arc beyond the fact that it consists of 23 episodes and continues the saga.
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."
Consequence: I cannot write a 160-220 word summary of the narrative arc because the source material does not contain it. If I write a summary based on general knowledge, I violate the core instruction. If I write a summary based only on the provided text, it will be about 15 words long, which violates the length constraint.
Decision: I must adhere to the instruction "If a detail is not in the provided material, you omit it rather than guess." However, the prompt requires a specific word count. Usually,
