Wrong file type

Error message

Wrong file type

What it means

Guard in edit_prediction's apply_diff when processing a unidiff event stream: a FileEnd event arrives (optionally carrying a rename target) before any Hunk event opened a current file, meaning the diff stream is malformed or the parser skipped the file header.

Solutions

1. Check that the unified diff being applied is well-formed and starts with file headers
2. Verify the diff producer (model output or tool) isn't emitting truncated diffs
3. Re-generate or re-fetch the diff and retry the application
