- Limitations
- This is WWII shipbuilding-era evidence, not a hull record. It does not name LSM-209, Dravo Corporation, the LSM-1 class, or any product aboard this ship; it does not establish onboard presence, quantity, location, condition, individual exposure, or causation.

[3]DANFS mirror probe: ibiblio HyperWar LSM-209 path (404) and sister USS LSM-213 path (200) [nhhc_danfs]

- HTTP response check; search_ledger rows sl-uss-lsm-209-lsm209-02 through sl-uss-lsm-209-lsm209-04
- Finding type
- historical_record
- Finding
- No individual DANFS/NHHC narrative entry was located for USS LSM-209. A direct probe of the established ibiblio DANFS mirror's LSM-209 path returned HTTP 404, while the equivalent sister-hull LSM-213 path returned HTTP 200. No ship-specific asbestos survey, abatement record, material inventory, or hazmat disclosure was located in the public sources searched.

- Limitations
- A missing public DANFS entry and failure to locate other public hull records do not prove the absence of asbestos or of undiscovered records. CourtListener results are expressly excluded from this negative finding because its required authenticated sweep could not run during the fleet pacing stand-down.

- Locator
- Commissioned-ship retention and 1941-and-later custody sections
- Finding type
- historical_record
- Finding
- NARA states that deck logs of commissioned U.S. Navy ships are retained permanently and that logs dated 1941 and later generally are held at the National Archives at College Park. As a commissioned 1944-45 Navy ship, LSM-209 may have deck-log records in Record Group 24; NARA's general guidance does not confirm that this hull's logs survive or are digitized.

- This is an archival-pathway record, not evidence that a LSM-209 log or asbestos record exists. No item-level catalog or reproduction retrieval was completed; deck logs may document events but are not presumed to be material inventories.
