+
+The translation designer's preview draws the groups of the schema it validates a bundle against (objectui#11765).
+
+The designer judges a translation draft by the per-app `TranslationDataSchema` groups, but the preview drew a hand-kept list that had drifted from them. It left out `picklists`, `datasets`, `pages`, `flows` and `settingsCommon`, so a spec-valid bundle of only one of those groups read as empty. It also listed `validationMessages`, which the spec removed, and `settings`, which only the platform schema declares. Both counted toward the coverage denominator, so a spec-valid bundle could never reach full coverage.
+
+The preview now draws one card per schema group, in the schema's order, and divides coverage by that count. A key the schema refuses is not drawn and not counted. A nested entry of a single key now reads `{1 key}` rather than `{1 keys}`.
+
+Nothing is added to the package entry: no export, prop, type member or language-pack key. The new headings are rows of the designer's own string table.

+ * objectui#11765 — the translation preview's categories are the groups of the
+ * schema the designer validates against.
+ *
+ * The designer judges a translation draft with `validateMetadataDraft`, which
+ * binds `TranslationItemSchema`: the groups of the per-app
+ * `TranslationDataSchema` plus the item's own keys. The preview used to draw a
+ * hand-kept list that had drifted from those groups. It omitted `picklists`,
+ * `datasets`, `pages`, `flows` and `settingsCommon`, so a spec-valid bundle of
+ * only one of them read as empty. It listed `validationMessages` (removed by
+ * the spec) and `settings` (a platform-only group the per-app schema refuses),
+ * so both counted toward the coverage denominator and a spec-valid bundle could
+ * never reach full coverage.
+ *
+ * Every spec-valid fixture here is parsed by the installed spec's
+ * `TranslationDataSchema` and passed through the designer's own
+ * `validateMetadataDraft('translation', …)` before it is mounted. The expected
+ * groups, their order and their count are read from `TranslationDataSchema`
+ * itself, so a spec group added or dropped turns these pins red instead of
+ * drifting. Headings and count rows are read back through `t` / `tFormat`
+ * rather than restated.
