[7]Authenticated CourtListener helper sweep attempted for exact-name opinion/docket and hull-number opinion/docket queries; fleet pacing guard blocked completion after the four base requests were issued. [court_record]

- Finding type
- historical_record
- Finding
- No litigation classification is made from CourtListener in this session: all four required base queries were attempted through the authenticated helper, but the fleet-wide pacing guard returned no result payload. The sweep is incomplete, not a finding of no litigation.

[8]Batch-7933 official-source search ledger: NHHC casualty and final-report pages, NARA Special List No. 44, NHHC PC-461 class reference, GAO HRD-80-2; Firecrawl search/scrape unavailable because the hosted keyless quota reported a roughly 24-hour wait. [other_primary]

- Search ledger rows sl-uss-pc-558-pc558-01 through sl-uss-pc-558-pc558-07 in BATCH-7933-REPORT.md
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located in the authoritative sources reviewed: no survey, insulation specification, abatement contract, hazmat disclosure, or ship-specific asbestos litigation record was found for PC-558. The record remains an honest class/era inference only.

- Limitations
- A negative public-record search does not prove absence of asbestos aboard. Firecrawl access and CourtListener litigation review were blocked, so archival and litigation coverage gaps remain. No claim about asbestos presence, absence, quantity, or exposure eligibility is made.
