The 4 'ambiguous' citation items flagged for chair turned out to be dead
orphan stubs: 0 inbound/outbound edges across all 5 citation mechanisms,
0 full_text, 0 halachot, 0 chunks/embeddings. A corpus-wide check found 15
such orphans total (incl. clean-looking ones). Per OpenCitations (keep an
id-less entity only if it is CITED — these are cited by nothing), these are
pure noise → deleted, not chair-judgment.
- 15 orphan cited_only stubs deleted (cited_only 46 -> 31); backup in
data/audit/fu2b-orphan-stub-cleanup-*.json.
- 0 malformed / 0 orphans remain; all 31 remaining stubs are cited.
- Combines with the 3 earlier mechanical normalizations. #70 fully done.
- Known forward-edge (no current data, no task): '+' combined-citation
handling in citation_extractor if it recurs in future extraction.
