1. The `RawTags[]` blob's `driverDataType` or `dataType` field (both
spellings accepted — the typed editor writes `dataType`, the driver's own
`tags[]` shape uses `driverDataType`).
`tags[]` shape uses `driverDataType`). **`driverDataType` wins when it is
non-blank**, and a present-but-invalid one rejects the tag rather than
falling through to `dataType`. The AdminUI's typed editor mirrors that
precedence on load and **normalises onto `dataType`, dropping the alias, on

driver read for it, and an unreadable spelling is refused at authoring
instead of dying at the driver.
2. A matching `Tags[]` entry naming the same DataItem id.
3. The Agent's own `/probe` declaration, via `MTConnectDataTypeInference.Infer`
(category/type/units/representation → `DriverDataType`).
