## Definition
**Narrative Constraint is the governance of an agent through an authored account of who it is, what world it inhabits, which futures are available, and which actions remain intelligible.** The constraint works most efficiently when it is experienced as biography or reality rather than command.
## Cross-Corpus Context
Westworld hosts inhabit assigned loops. Pantheon's Caspian grows inside an engineered biography. Person of Interest shows predictive systems narrowing action through classification and selective disclosure. [[wiki/The Thirteenth Floor (1999)|The Thirteenth Floor]] turns narrative constraint into world architecture: inhabitants receive a coherent past and horizon that conceal the surrounding stack.
## Key Distinction
Stories can coordinate identity without eliminating agency. Constraint becomes domination when the author retains hidden power to revise the subject's memory, environment, or future without contestability.
