{
  // Type-checks this package's TESTS, which `tsconfig.json` excludes.
  // See `packages/types/tsconfig.test.json` for why that exclusion was a hole:
  // the build correctly keeps tests out of `dist`, but nothing else compiled
  // them, so a test could assert a contract the compiler never checked. Here it
  // hid two reads that could never have worked: `DashboardRenderer.filters` and
  // `DatasetWidget` both declared their `queryDataset` / `find` mocks with NO
  // parameters, so `mock.calls` typed as empty tuples and every `calls[0][1]`
  // the drill and broadcast assertions are built on read out of bounds — cast,
  // so invisible at runtime too (objectui#4040).
  //
  // Chained from this package's `type-check` script, which is what the CI
  // `Type Check` job runs; scripts/check-type-check-coverage.mjs enforces the
  // chaining — a config nothing runs is the objectui#3009 failure itself. This
  // package was the last TEST_DEBT entry, so that table is now empty.

    // listed even though 18 suites use its matchers — measured too: removing it

    // exception — `@object-ui/plugin-charts/*` mapped to that package's source —
    // because two suites imported subpaths the package does not publish (its
    // `exports` map declares `"."` alone), so they resolved only through the
    // repo's vitest alias. objectui#4529 ruled both, and both imports now go
    // through the published root entry, so the mapping is gone rather than
    // maintained:
    //   - `normalizeChartSchema` is a genuine cross-package contract — the
    //     assertions run the emitted schema through the SAME translation layer
    //     the runtime applies — so plugin-charts publishes it from its entry.
    //   - `AdvancedChartImpl` was an eager pre-warm of a chunk production only
    //     ever reaches through `React.lazy`; the surface does not grow to keep
    //     an eager deep import alive (objectui#4325 / PR #4460), so the import
    //     is gone and the wait it shortened is budgeted explicitly instead.
