Lookup parameter: maps a wire integer → Domain string via a fixed labels
table, routing unknown codes through a fallback. Inherently decode-only
(encode always fails with readOnlyEncodeFailure); use for monitor
registers that report fault/alarm/model codes as human-readable text.
The optional domain schema supplies a target for decoded strings.
