Signature, parameters, and return type

/**
 * 인메모리 dedupe — 단일 프로세스 한정. 분산 환경은 Redis `SET NX` 등으로 대체할 것.
 *
 * `stateOf` answers "what state is this key in right now?" without the side effect a probing
 * `claim()` has (a claim after `release` would re-occupy the key as `processing` and poison
 * later assertions). `undefined` means the key is unknown or was released — i.e. claimable.
 */
declare function memoryDedupeStore(): WebhookDedupeStore & {
    stateOf(dedupeKey: string): 'processing' | 'completed' | undefined;
