## Capability Surface
`ModbusDriver : IDriver, ITagDiscovery, IReadable, IWritable, ISubscribable, IHostConnectivityProbe, IPerCallHostResolver, IDisposable, IAsyncDisposable`
(`Driver.Modbus/ModbusDriver.cs`). There is **no `IAlarmSource`** and no
`IHistoryProvider` — the Modbus protocol expresses neither, so those capabilities
are out of scope by design.
(`Driver.Modbus/ModbusDriver.cs`). There is **no `IAlarmSource`** — the Modbus protocol has no
alarm object, so that capability is out of scope by design. (No driver carries a
history capability; history is server-side.)
