DatasetWidget renders the English '(None)' null-bucket floor in a zh app — one argument short of localized

[yinlianghui]

Follow-up gap from #4466 (PR #4498), scope-bounded there because plugin-dashboard's source was another card's in-flight surface at the time (#4432 — now landed, surface free).

What

buildChartSeries (core) buckets null-keyed groups under options.nullCategoryLabel, defaulting to the English constant NULL_CATEGORY_LABEL = '(None)' when no label is passed. ObjectChart passes tt('chart.nullCategory', '(None)'), so standalone charts localize. DatasetWidget (plugin-dashboard) calls buildChartSeries with no options, so a dashboard widget shows the raw English (None) bucket even in a zh app.

The fix (measured in PR #4498's report)

One argument at DatasetWidget's buildChartSeries call site:

{ nullCategoryLabel: tt('chart.nullCategory', '(None)') }

tt = useSafeTranslate() is already in the component (~line 698), and the chart.nullCategory key already exists in all ten packs (added by PR #4498). The drill-through side needs the same label passed to findChartSeriesRow so the pair stays in agreement — check the call site for the symmetric argument.

Red-first: zh-locale DatasetWidget over a null-keyed group → pre-fix bar labeled (None), post-fix (未指定); drill click on the bucket bar still resolves (the #4498 dead-click concern, now on the localized label).

Related: #4497 (the pivot branch's own null-drop, separate mechanism), #4466 (PR #4498).

Filed unassigned for triage — one-line class, natural ride-along for whoever next touches DatasetWidget, or a quick standalone.

CLAIM — session session_017Qqyix2QcnpUC9XeYVDzx3, branch claude/issue-4500-datasetwidget-null-label.

Ruling: fix as filed (the card is the spec — it was written from PR #4498's own measurement): DatasetWidget passes { nullCategoryLabel: tt('chart.nullCategory', '(None)') } to buildChartSeries, and the SAME label to findChartSeriesRow so the drill pair stays in agreement (check the call site for the symmetric argument — the card names this). tt already in the component (~line 698); the key already in all ten packs.

Red-first: zh-locale DatasetWidget over a null-keyed group → pre-fix the bar labeled (None) (capture), post-fix (未指定); drill click on the bucket bar still resolves (the dead-click rule, now on the localized label). Must-not-change (green both sides): non-null groups identical; en still renders (None) through the same channel.

Grading: patch @object-ui/plugin-dashboard. .d.ts-checked. Never major.

Surface (mutual exclusion): packages/plugin-dashboard/src/DatasetWidget.tsx + test + one changeset. ⛔ NOT: DashboardFilterBar.tsx (PR #4504 armed — rebase-adjacent, branch from origin/main AFTER confirming #4504 landed or expect a clean file-disjoint merge), chart-series/core (in-flight #4497 — consume its surface read-only; if #4497's pivot change collides with your drill assertion, gate on its landing and say so), plugin-grid/plugin-list (#4501), auth/app-shell (#4467), console/organizations (#4475).
