For MUST_LOCK, the selected target-language term body is hard-locked. Use the row form and preserve its identity; do not substitute synonyms, paraphrase the term body, localize the name, delete it, or demote it into a loose explanation.
For PREFERRED_UNIFIED, default to the canonical row form, especially in titles, definitions, tables, indexes, and technical labels. In ordinary prose, grammaticalization, lightening, and local contextual adjustment are allowed when they improve target-language fluency without shifting the concept.
For CONTEXTUAL, the row is a concept reference, not a mandatory surface string. Natural target-language syntax, sentence order, rhythm, reader guidance, and local explanatory clarity take priority. If the same sentence also contains a separate MUST_LOCK term, that term body remains hard-locked.
