instruction suffix file is empty

Error message

instruction suffix file is empty

What it means

The file given via --instruction-suffix-file was read successfully but its contents are empty/whitespace-only, so appending it would add nothing. An ensure! guard (analogous to the main instruction check) rejects the empty suffix file as a usage error.

Solutions

1. Put the intended suffix content (few-shot examples, extra constraints) into the file
2. Omit --instruction-suffix-file entirely if no suffix is needed
