The card said one column. The apply wrote two.

A bug in a language model's SQL update proposal caused it to silently ignore a column being updated, leading to unintended changes. This was due to a mismatch between the columns shown in the proposal and those actually written by the SQL statement. The fix involves updating the logic that determines which columns to show in the proposal. This bug matters because it can lead to data corruption and security issues if not caught. To fix, review and update the logic for generating the proposal card, ensuring it accurately reflects the columns being updated.
