/**
 * Read a stored event (its entities and variable values) back from Amazon
 * Fraud Detector — the effectful lookup call made from a deployed Lambda or
 * Task. Events are stored by `SendEvent` or by predictions on an event type
 * with ingestion enabled.
 *
 * ### Reading Stored Events
 * Provide the `GetEventHttp` implementation layer on the Function effect,
 * bind the event type in the init phase, then call the returned client at
 * runtime. The binding grants `frauddetector:GetEvent` on the event type and
 * injects its `eventTypeName` automatically.
 *
 * **Example:** Read from a Lambda
 * ```typescript
 * // init
 * const getEvent = yield* FraudDetector.GetEvent(eventType);
 *
 * return {
 *   fetch: Effect.gen(function* () {
 *     // runtime
 *     const { event } = yield* getEvent({ eventId: "order-123" });
 *     return HttpServerResponse.json({ variables: event?.eventVariables });
 *   }),
 * };
 * // on the Function effect:
 * // .pipe(Effect.provide(FraudDetector.GetEventHttp))
 * ```
