//! `mxaccess-callback` — `INmxSvcCallback` RPC server (the callback exporter).
//!
//! M2 wave 3 landed: the [`exporter`] module ports
//! `src/MxNativeClient/ManagedCallbackExporter.cs` to a tokio-based TCP
//! server that serves `IRemUnknown` and `INmxSvcCallback` opnums and emits
//! typed [`exporter::CallbackEvent`]s for diagnostic observation.
//!
//! Opnums (verified against `src/MxNativeClient/NmxSvcCallbackMessages.cs:11-12`):
//! - `3` `DataReceived(bufferSize: i32, dataBuffer: sbyte[bufferSize]) -> hresult`
//! - `4` `StatusReceived(bufferSize: i32, statusBuffer: sbyte[bufferSize]) -> hresult`
//!
//! Plus the `IRemUnknown::RemQueryInterface` handler that completes the
//! server-side handshake against our exported OBJREF (DoD condition for M2).
