  // 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.
  //
  // This project is now the ONLY one that compiles `spec-symbol-batch7.test.tsx`,
  // whose whole value is compile-time assertions (objectui#3181). It used to be
  // rescued by a narrow `tsconfig.typetests.json` next door, which named that one
  // file while the rest of the tree was still in TEST_DEBT; the package graduated
  // in objectui#4040 and the narrow project was retired in objectui#4291, after
  // `--listFiles` showed this project reads the same file and a provably-false
  // `Assert` appended to it turned this project red. Keep the file compiling
  // here: those assertions are erased at runtime, so vitest proves nothing
  // about them and `tsc` is the only thing that can.
