    historical_record
    Finding
    No ship-specific asbestos documentation was located in the available official DANFS entry or NARA logbook index. This is a limited negative finding: the Firecrawl MCP search service was rate-limited before source-specific searches could run, and authenticated CourtListener exact-name and hull-number results could not be obtained because the fleet pacing limiter stopped the initial helper request before an API response.

    Limitations
    This records only that no asbestos document was located in the limited materials actually reviewed; it is not proof asbestos was absent. No CourtListener no-result conclusion is made. The litigation sweep remains incomplete, and this row supports unknown asbestos status only.
