[5]Batch-9128 CourtListener search ledger: authenticated helper invocations for exact-name and hull-number opinion/docket base queries [other_primary]
- Locator
- search_ledger sl-uss-yms-49-yms49-07 through sl-uss-yms-49-yms49-10; each helper stderr log records authenticated-request initiation but no HTTP response
- Finding type
- historical_record
- Finding
- The four required authenticated CourtListener base-query invocations were initiated for exact-name and hull-number opinion/docket searches, but none returned a result before this environment's 30-second command-execution cutoff. No asbestos-qualified variant was run because no completed base query established a 20-result overflow.

- Limitations
- This is an incomplete litigation sweep, not a negative finding. The helper was used for every invocation; no anonymous request, raw API request, v3 request, retry loop, or asbestos variant was used. No conclusion about qualifying asbestos litigation, exposure, causation, or legal eligibility may be drawn.
