CSV with AI now parses in chunks and fails honestly
CSV with AI now infers how to read your file once, then runs that plan locally in chunks of 2,500 rows, with a running rows processed count as it goes. Large files no longer sit on a batch state that reports success while zero trades actually loaded.
What Review Trades tells you
On the Review Trades step, a status line explains what actually happened: Parsed from the file columns when your headers were enough, or Order fills were paired into trades when the file needed order pairing. Once formatting finishes, the state changes to Ready to import. Very large previews show only the first trades, while the full formatted set is still queued for import.
Missing AI configuration now fails closed
If your server has no OpenAI API key configured and the file's headers alone aren't enough to build a plan, import stops with AI formatting is unavailable. Ask your administrator to configure an OpenAI API key, then try again. — rather than the previous silent "0 of N trades formatted" success. If a plan still comes back incomplete, the review step names the missing columns so you can map them to continue.
This is a reliability follow-up to AI CSV field mapping; it doesn't change how columns get mapped in the first place.
