The Clamshell Doctrine manifests as translucent smoke-gray plastic housing with a spring-loaded hinge mechanism—closed for protected players, perpetually hanging open for those who miss events. Each case bears a rental history sticker tracking every simulation appearance, with the magnetic tape inside visibly degrading when exposed versus pristine when sealed. The doctrine exists in a quantum state of shelf positioning: premium spine-out display for consistent attendees, face-down in the bargain bin for dropouts.

Serves as the Chaintrix's preservation authority, granting clamshell protection to consistent players while leaving no-shows' recordings exposed to dust, heat, and magnetic degradation across all 16 movie simulations.
