Story references and their limits

[S1] Disney+ — In Time, official synopsis and credits. 2011; directed by Andrew Niccol, starring Justin Timberlake and Amanda Seyfried. Fictional lifespan currency is a narrative analogy, not Kerala’s proposed credit mechanism. No scene dialogue is quoted.

[S2] Kerala Tourism — The Mahabali legend. Official tourism account of the Onam tradition; folklore, not historical proof or a Vedic origin for time banking. The connection to inclusion is the author’s interpretation.

[S3] Michael Ende — Momo. Author’s official site: original publication 1973; listening protagonist and lifetime-stealing grey gentlemen. Based on this primary book description, not a claim to have newly reviewed the entire novel. Literary analogy, not programme evidence.
