- Finding type
- historical_record
- Finding
- No qualifying CourtListener hit was classified from the four required base-query invocations because the authenticated helper emitted request diagnostics but no result payload in this session; this is an incomplete search, not a finding that no case exists.

- Limitations
- The helper did not provide result JSON, so hits could not be read or classified. This row is only a process-status record and is not evidence of no litigation. No asbestos-qualified variants were run because no base-query overflow was observable.
