[7]Batch-7465 source review and search ledger: NHHC DANFS, NavSource, NARA Special List No. 44, PubMed, GAO, and authenticated CourtListener helper attempt [other_primary]
- Locator
- search_ledger rows sl-uss-lst-922-lst922-01 through -09
- Finding type
- historical_record
- Finding
- No ship-specific asbestos record was located in the DANFS, NavSource, or NARA materials reviewed: no asbestos survey, abatement contract, hazmat disclosure, or material schedule naming LST-922 was found. The CourtListener litigation sweep was not completed after the authenticated helper returned the fleet-wide pacing stand-down, so no litigation conclusion is drawn.

- Limitations
- This is a finding about records located, not proof that asbestos was absent. CourtListener coverage is incomplete because the authenticated fleet limiter stopped the request; exact hull and docket searches were not run and no anonymous or raw API request was made.
