Li & Torr's 1992 APS conference abstract remains unlocated after a multi-route search, leaving its 'generator' quote resting on a single, uncorroborated transcription

The 1992 American Physical Society conference abstract at the root of the vault's "generate gravity in the laboratory" claim — Li & Torr, "The Gravitoelectrodynamics of Superconductors: A Theoretical Basis for a Principle of Electrically Induced Gravitation," Bull. Am. Phys. Soc. 37(2), 1992, Session G8 paper 10 — could not be located directly after a genuine multi-route search. APS's own meeting-archive index (meetings-archive.aps.org) lists March Meeting years only from 2005 to 2024; no earlier APS archive portal was found. HathiTrust's catalog, Google Books-style search, and the Internet Archive's holdings of the Bulletin of the American Physical Society (which digitizes scattered volumes from 1925–1932 only) turned up no copy of Volume 37 (1992). No secondary source located this session engages with the abstract's actual wording either — not Kowitt's 1994 Physical Review B critique, not Harris's 1999 rebuttal, not the Wikipedia article on Ning Li.

The abstract is known to this vault, and apparently to the wider accessible record, only through a 2010 Defense Intelligence Agency survey document's own transcription of it — re-confirmed this session as grounded in that document's text, but that re-confirmation checks the DIA document against itself, not against the abstract it is quoting. This is the same shape as the 1994 UAH preprint that also could not be found in this claim-family: a genuine, dated non-resolution rather than a research shortfall. Per sources.md's single-source concentration cap, only one claim-note currently rests on this abstract's content, so the cap itself is not in play — but that one note's grounding is, and will remain, as strong as a single unrefereed, unarchived transcription and no more.
