[4]CourtListener authenticated API v4 required base-query sweep attempted through the fleet helper [court_record]
- Locator
- Search ledger sl-uss-pc-499-pc499-01 through -04; helper diagnostics reported fleet pacing budget spent
- Finding type
- litigation_documented
- Finding
- The four required authenticated base searches were invoked for exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket. The fleet pacing limiter denied each request before a result payload was returned; therefore no litigation classification or search negative is asserted.

- CourtListener opinions and RECAP dockets
- Limitations
- This is an access gap, not evidence that litigation does not exist. No asbestos-qualified variants were run because the base requests did not return result pages and variants are not permitted when a base query cannot establish overflow. No anonymous, raw, curl, or v3 request was made.
