- These are the source's hull specification figures; no official LSM-15 technical record was located to independently verify them. The diesel specification establishes no boiler or turbine plant, but it does not identify insulation or asbestos content.

- Finding
- The National Archives at Atlanta public finding aid for RG 181's Charleston Navy Yard Ship Commissioning Files (NAID 2694599) describes a 1942-1945 series of commissioning correspondence and lists Landing Ship, Medium hulls beginning with LSM-126; LSM-15 is not listed in this public container list.

- Finding type
- asbestos_application
- Finding
- Corn and Starr's peer-reviewed historical study documents extensive asbestos use as fireproofing and insulation in U.S. shipbuilding during World War II. For LSM-15, this supports only class/era context: possible applications on a diesel landing ship include machinery insulation, exhaust lagging, pipe insulation, gaskets, packing, electrical insulation, and fireproofing. The study does not name LSM-15 or establish that any listed product was installed aboard it.

[6]Batch-5952 source review: NavSource USS LSM-15 page; NARA RG 181 finding aid; NHHC/DANFS and NVR availability checks; Firecrawl quota-block notice [other_primary]

- search_ledger rows sl-uss-lsm-15-lsm15-01 through -07
- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the searched public sources: no asbestos survey, abatement contract, hazmat disclosure, material list, or ship-specific asbestos finding was found for USS LSM-15. The available hull history and NARA finding aid contain no asbestos or insulation-material statement.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. Firecrawl was unavailable because its hosted keyless quota required a multi-hour stand-down; direct authoritative fallback research was used. This row does not establish or defeat exposure, causation, or legal eligibility.

[7]CourtListener API v4 via /Users/charlesfletcher/devin-prompts/cl-auth-search.py: exact-name opinion query HTTP 200, count 0; exact-hull query pacing stand-down before HTTP [court_record]
- Locator
- search_ledger rows sl-uss-lsm-15-lsm15-05 and -06; helper outputs /tmp/cl-lsm15-name-op.json and /tmp/cl-lsm15-hull-op.err during research
- Finding type
- litigation_documented
- Finding
- Authenticated CourtListener API v4 exact-name opinion search for 'USS LSM-15' returned zero results. The required exact-hull-number opinion search for 'LSM-15' was then attempted through the same helper but stopped by the fleet-wide pacing limiter before an HTTP request. No hull-number result, asbestos litigation result, or legal inference is asserted.

- Limitations
- The exact-name opinion result is a limited no-result finding, not proof of no litigation. The exact-hull query did not reach CourtListener because the authenticated shared-fleet limiter instructed a stand-down. No anonymous request, raw request, v3 API, or retry loop was used; docket searches and hull-number opinion search remain unresolved.
