[2]Supplied Ships Batch 8371 scope correction, attributed to Trill fact-QA (crew signs 960-977), dated 2026-09-29; underlying crew-sign records were not provided for independent inspection [other_primary]

- Batch 8371 ship scope note
- Finding type
- historical_record
- Finding
- Correction carried from the supplied Trill fact-QA scope note: this hull was laid down under contract designation PCS-1453, redesignated YMS-477 on 27 September 1943 before commissioning, commissioned as YMS-477, and never served as PCS-1453.

- Study period
- 1943 (designation correction)
- Limitations
- This row preserves the explicit batch correction and is not an independently verified transcription of the underlying crew signs. No launch date, commissioning date, builder, or later service detail is established by this correction row. It establishes no asbestos fact.

- PDF p. 121, YMS-477 row
- Finding type

- Finding
- The National Archives' Special List No. 44, by ship number, indexes deck-log holdings for YMS-477 from 10 July 1944 through 30 June 1945.

- Population
- Navy ship's company; individuals not identified in the finding aid
- Limitations
- This is a finding aid for deck-log coverage, not the underlying logs. The logs were not reviewed; the index establishes neither the vessel's location or activity on a particular date nor any asbestos content or exposure.

- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, product identification, or other asbestos record was located in the bounded sources reviewed for this pass. Ship-specific asbestos documentation remains unknown.

- Study period
- 2026-10-04 research pass
- Limitations
- A bounded search result, not proof that no such records exist. Firecrawl search and scrape were unavailable because the keyless MCP quota was exhausted; NHHC and NVR access gaps are logged. NARA deck logs and other archival records were not reviewed for material content. No inference is made from ship class, construction date, or propulsion.

[5]CourtListener authenticated API v4 helper sweep through cl-auth-search.py, 2026-10-04; helper pacing stand-downs and lost command output are recorded in search_ledger [court_record]

- Search ledger entries sl-uss-yms-477-05 through sl-uss-yms-477-08
- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation conclusion can be drawn from this pass. Four required authenticated CourtListener base queries were attempted through the fleet helper: the exact-name opinion query's output was not retained by the command session, and the exact-name docket plus both hull-number queries were declined by the fleet-wide pacing gate. No query result was available to classify as a hit or zero result.

- 2026-10-04 litigation search
- Limitations
- This is an access-gap record, not a finding that litigation does not exist. The exact-name opinion query was not repeated because it had already been attempted. No asbestos-qualified variants were run because no base query returned a count or a 20-result overflow.
