| """The OCR guard must actually skip when there is no engine. |
| |
| This is a regression test for a real bug: the guard in `test_cli.py` asked |
| `detector_available()`, whose default `auto` is `True` even with nothing |
| installed - because the grid fallback always exists. So on a machine with no OCR |
| engine the test *failed* instead of skipping, and the failure looked like a |
| harness defect. The guard now asks for `ocr` specifically, and here is the proof. |
