SNS fan-out to SQS works today with filter policies, and EventBridge is implemented with rule matching and targets. Delivery is synchronous by default (deterministic for tests), but I'm planning a `/_fakecloud/config/sns` API to let you configure delivery delays, ordering, and failure rates per topic. That way you can test eventual consistency scenarios without changing your app code. Also, a PHP SDK is in the works and should be out by end of day.
