package event

import "ior/internal/types"

// --- compile-time interface satisfaction assertions ---
//
// Every generated concrete event type in internal/types must satisfy the Event
// interface (which composes EventIdentity and EventLifecycle). These assertions
// live in the event package rather than in the generated file so they are not
// overwritten by mage generate. The event package already imports types, so no
// new import cycle is introduced.
