Supplementary Data for: What Does a Factual-Error Detector Really Measure?

Two exploratory checks added after reproduction package 1.0.1 (Zenodo, 10.5281/zenodo.22640344)
and cited in Supplementary Section A.3 and the artifact map in A.5:
  reproduce/scripts/reviewer_span_match_sensitivity.py  -> reproduce/derived/reviewer_span_match_sensitivity.json
  reproduce/scripts/reviewer_span_annotation_audit.py   -> reproduce/derived/reviewer_span_annotation_audit.json
Inputs are the files of package 1.0.1 (repro_pack/data_inputs/answer_tokens/) and the stored NQ extraction
(data_inputs/dual/nq/); paths are documented in each script header.
