    "notes": "By-design false-negative fixture per spec OQ-5 / C-V6(a). This citation is FABRICATED (fabrication_intent=true) but carries NO DOI and NO arXiv ID — only a bogus title. With no resolvable identifier to key on, every resolver can only title-search, producing title-only unmatched (queried_by=title). The narrowed-false definition (C-V6(a)) classifies this as unresolvable, NOT false: a no-identifier fabrication is indistinguishable from a legitimately-unindexed regional/non-English paper, and the existence gate accepts this recall limit by design (the v3.8 claim-faithfulness audit + human review catch it instead). This fixture pins that the narrow does NOT promote a title-only unmatched to false even under a would-be strict policy."
