State Cards and State Capsules

A State Card is the named library item you select in ScenarioDeck. It points to a State Capsule, the immutable local artifact that stores safe state required to replay a useful application state.

Changes do not silently rewrite a source capsule. When you change routing or a captured response, ScenarioDeck creates a derived experiment or revision. This lets you return to the original state reliably.

State Capsules are credential-free. An optional Auth Persona requirement belongs to the State Card; the machine-local Auth Binding that satisfies it is separate.
