Class RpcEventRegistryInternal

Classify an attempt to announce (emit) an event on the network against the registry. Used to warn about misuse without blocking the announcement.

• 'ok' — the announcement is valid: the event is multi-source (any process may announce it, whether or not it registered), or it is single-source and announced by its registrant.
• 'unregistered' — the event is single-source and no process has registered this name centrally. Emitting a single-source event that was never registered is deprecated (it does not appear in the OpenRPC document).
• 'foreign-single-source' — the event is single-source but is being announced by a handler that did not register it; only the registering process should emit a single-source event.

Whether any handler has centrally registered this event name.

Try to register an event. Returns true if accepted, false if rejected.

• Name in MULTI_SOURCE_EVENT_NAMES (multi-source): multiple handlers may register; same handler twice rejected.
• Name not in MULTI_SOURCE_EVENT_NAMES (single-source): first registrant wins; any subsequent registration from any handler is rejected.

Remove a registrant. Returns true if the handler had registered this event.

Remove all event registrations for the given handler (e.g. when a websocket closes)
