Most of ai-bookkeeper's bank readers were written from memory, so this run tried a file someone else produced: the import fixture of Maybe Finance (Date, Name, Amount, Category, Tags, Account, Notes).
All nine lines read, and import --map with the three account names split them across the right ledger accounts. No bug found. The file is AGPL, so it is not copied into the repo; the result is recorded in the README's Verification list. Nine rows is thin evidence, and the file is not a bank's own download. Still wanted: real exports from named banks.
