Last one. The starter has a regression_cases list and a stub classifier that has a known bug — it returns "no" for the input "cancel my account", which should be "yes". Add the missing case to regression_cases so it would catch this exact bug. Run the suite and confirm the output is 2/3 (two pass, one — the new regression case — fails).

Add one entry: input "cancel my account", expected "yes", name "account_cancel".

Expected output:
