The changespec.com domain continues as the commercial hosted aggregator.

The protobuf definition is normative for systems using gRPC or binary-efficient transports; the JSON encoding remains the default on the wire for HTTPS, RSS, and MCP. Cross-encoding compatibility is guaranteed - the same logical event round-trips through either representation without loss.",
