{
  // Type-checks this package's TESTS, which `tsconfig.json` now excludes.
  // Template: `packages/plugin-dashboard/tsconfig.test.json` (objectui#4530);
  // rationale: `packages/types/tsconfig.test.json`. A test nothing compiles can
  // assert a contract the compiler never checked and then read as evidence that
  // the contract holds (objectui#3009).
  //
  // As in `@object-ui/fields`, the hole is new and deliberate: until
  // objectui#4006 this suite was checked only as a side effect of the build
  // config having no test exclude, which is also how `dist/index.test.d.ts`
  // came to be published. The exclude and this project are one change —
  // scripts/check-type-check-coverage.mjs fails 5c on the exclude alone
  // (measured).
  //
  // Chained from this package's `type-check` script, which is what the CI
  // `Type Check` job runs; the coverage gate enforces the chaining.
