CSV shape
One row per prompt, one column per candidate:param: attach generation settings to each output. They power the parameter insights in settings evaluations.
Media limits
Limits are checked before a transfer starts, so you never sit through an upload that was going to fail. Large uploads resume after a dropped connection, and files you already uploaded are recognized and skipped instead of transferred again.
Validation
Every import is validated before anything reaches voters. Issues appear next to the rows they affect, each with a specific fix, for example “Add at least two variant/output columns.” Rows are marked ready or blocked, and ready rows can proceed while you repair the rest.The Outputs tab is read-only on phones. Use a tablet or desktop to import or repair data.
