**STOP on any failure.** Use the table below to suggest fixes for `[X]` items.
# Offer suggestions then ask before proceeding
For each failed check, show the user the suggested fix from the table below and **ask if they want you to run it**. Do NOT automatically execute fixes — wait for user confirmation before taking action.
