Struct InMemoryReplayGuard 

pub struct InMemoryReplayGuard { /* private fields */ }

A process-local replay guard for tests and low-traffic, single-replica services.

Claims are not shared between processes, so this only protects a single replica. Use a shared store when the service runs more than one. Each claim scans the entire map under a mutex to remove expired entries, so use a shared store with native expiry for production traffic.
