Done.

Generated files:
- Latest parser output: $OUTPUT_ROOT/outputs
- Editable copies:      $EDITABLE_DIR
- Candidate fixtures:   $OUTPUT_ROOT/candidate-fixtures
- Summary report:       $OUTPUT_ROOT/report.md
- Machine index:        $OUTPUT_ROOT/index.json

Recommended workflow:
1. Edit files in: $EDITABLE_DIR
2. Keep only the fields you really want the extractor to produce.
3. Once reviewed, copy the corrected files into an approved fixtures directory.
4. Re-run the benchmark and compare actual vs approved output.
