  // rest; the matchers were always registered at runtime, but with the setup file outside "src"
  // the compiler never saw the augmentation and reported 786 phantom errors across the tests.
  // _TESTS is the test tree, moved out of src so it never reaches the plugin ZIP. It stays in this

  // out of the type ratchet while the count went DOWN and read as an improvement.
