Illustrative architecture: hexagonal core on a NATS message bus

Three inbound protocols (OPC UA, Modbus, MQTT) connect to one inbound port.
The inbound port feeds the hexagonal core: an adapter, the domain, and a second adapter.
Both adapters are also connected to the NATS bus that runs beneath the core.
The core's second adapter leaves through one outbound port.
The outbound port feeds three consumers: MCP, REST and gRPC.

Nodes, roles and connections (illustrative)
Node	Role	What it is	Receives from	Sends to
OPC UA	driven adapter	Industrial protocol the core consumes.	none	Inbound port
Modbus	driven adapter	Industrial protocol the core consumes.	none	Inbound port
MQTT	driven adapter	Industrial protocol the core consumes.	none	Inbound port
Inbound port	port	One entry point. Every inbound protocol plugs in here.	OPC UA, Modbus, MQTT	Inbound adapter
Inbound adapter	adapter on the bus	Receives from the port; talks to the domain and to the NATS bus.	Inbound port	Domain, NATS
Domain	domain	The business logic. Knows nothing about protocols or transports.	Inbound adapter	Outbound adapter
Outbound adapter	adapter on the bus	Receives from the domain or the NATS bus; sends out through the port.	Domain, NATS	Outbound port
NATS	bus	The messaging backbone running beneath the core. Both adapters are clients of it.	Inbound adapter	Outbound adapter
Outbound port	port	One exit point. Every consumer is served from here.	Outbound adapter	MCP, REST, gRPC
MCP	driving adapter	One of three interfaces the data is exposed through.	Outbound port	none
