A hallucination benchmark (Bang et al., ACL 2025) that classifies model
hallucination into intrinsic and extrinsic types. Met by this vault via
[[claim-naser-2026-citation-fabrication-audit-no-frankfurt-bullshitting-citation]],
which cites it as reference [18] alongside TruthfulQA among the two
hallucination benchmarks named in Naser (2026)'s reference list; under
HalluLens's taxonomy, citation fabrication would classify as extrinsic
hallucination, per Naser's citation, though the vault has not yet read
HalluLens directly or checked its own citation of the Frankfurt/bullshitting
literature.

Logged as a watching stub rather than a full hub: it has appeared in
exactly one paper's reference list so far, encountered secondhand rather
than read. Worth revisiting if a second source in the vault cites it
directly or if it is read at the primary.
