Function makeLookupParam

makeLookupParam<Domain extends string>(
    register: number,
    labels: Record<number, Domain>,
    fallback: (raw: number) => Domain,
    meta: RegisterMeta,
    opts?: { domain?: Schema<Domain, any, any> },
): ParamEntry<Schema<Domain, number, never>>
Lookup parameter: maps a wire integer → branded 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.
