   Critical rules:
   1. SEARCH content must match the associated file section to find EXACTLY:
      * Do not refer to the `diff` argument of the previous `replace_in_file` function call for SEARCH content matching, as it may have been modified. Always match from the latest file content in <selected_files> or from the `view` function call result.
