EventValidator

Checks a track/screen event against an app-defined tracking-plan contract — a fixed set of event types, required properties, naming conventions — before it reaches the transport.

Autograph does not ship any rules of its own (every adopter's schema differs); this is the extension point for plugging app-defined ones in via AutographConfig.validator. Whether an invalid event throws or is dropped-and-logged is controlled separately by AutographConfig.strictValidation, not by this interface, so the same EventValidator works for both debug (fail fast) and release (never crash) builds. A validate that itself throws is treated as a rejection too, so a validator bug can't crash a non-strict build.

strictValidation's throw is synchronous, on the caller's thread — including composables that call track/screen from inside a LaunchedEffect (e.g. TrackScreenView), where it propagates as an uncaught exception in that effect's own coroutine, not through any Autograph- owned handler. Reserve strict mode for debug builds, where crashing on a tracking-plan violation is the intended behavior.
