详细描述

Envelope metadata shared by event domains.

The envelope carries identity, ordering and causal metadata only. The payload member is an opaque, canonical event-stream representation at the serialization boundary; a domain must keep its payload strongly typed and use GameEventLog::appendTyped to encode it. The stream never interprets that representation as a universal domain object.
