Superseded by the Homeboy Extensions default flip in Extra-Chill/homeboy-extensions#705. The runner now defaults WordPress plugin/theme tests to WP Codebox, so this repo-local canary workflow would preserve the old split instead of removing it.\n\nVerified after #705 merged by running the HBE router directly against Data Machine with WP Codebox: 1295 tests, 4148 assertions, 3 skipped, backend wp-codebox.
