+Metadata forms i18n: the `object.fields.reference` help text now carries the
+`tree` rule in Spanish, Japanese and Chinese, and no longer claims the field is
+for `lookup` / `master_detail`.
+
+The English source for this row gained a normative sentence on 2026-09-05 — a
+`tree` field's `reference` is optional and, when present, must name the
+declaring object; a link to a different object is a `lookup`. That rule is
+enforced at parse time, so an author who writes a foreign target meets it as a
+refusal rather than as guidance.
+
+The three translated locales still served the pre-2026-09-05 sentence. They
+were wrong in both directions at once: they dropped the `tree` rule entirely,
+and they asserted a purpose the source no longer states — "(para
+lookup/master_detail)" / "(lookup/master_detail 用)" / "(用于 lookup /
+master_detail)" — which the `tree` case contradicts. A Spanish, Japanese or
+Chinese console therefore told the author that `reference` was for the two
+relationship types that exclude `tree`, and gave no hint of the constraint they
+were about to hit.
+
+Only the three `helpText` values move. The `label` siblings, the key set and
+the generated structure are unchanged.
