## Definition
**A Cornerstone Memory is a high-weight autobiographical representation used to organize identity, motivation, and permissible action.** It may arise from lived experience, reconstruction, or deliberate installation.
## Cross-Corpus Context
[[wiki/Westworld S1E3 — Weaponizing The Cornerstone|Westworld]] makes the mechanism explicit when Ford gives Teddy a violent history capable of redirecting his behavior. [[wiki/Pantheon S2E5 — Yair|Pantheon]] presents traumatic memory as identity-relevant code required for repair. Caspian's engineered childhood shows the converse problem: a biography can organize a person even when its environment was staged. [[wiki/The Thirteenth Floor (1999)|The Thirteenth Floor]] asks the same question at world scale, where an apparently ordinary past is part of an implemented environment.
## Key Distinction
Causal importance does not prove authenticity, and artificial origin does not prove irrelevance. Provenance and present ownership must be evaluated separately.
