[3]Authenticated CourtListener search helper and fleet-wide pacing limiter; see search_ledger [other_primary]
- Locator
- search_ledger sl-uss-calistoga-yfb21-02 through sl-uss-calistoga-yfb21-05
- Finding type
- historical_record
- Finding
- No CourtListener result classification was possible: the authenticated helper's shared pacing limiter reported the fleet request budget momentarily spent. The four required base searches (name opinion, name docket, hull opinion, hull docket) therefore remain uncompleted; this is an access gap, not a no-result finding.

[4]Limited source review: 1941 Navy Filing Manual; see search_ledger [other_primary]
- Locator
- Search ledger sl-uss-calistoga-yfb21-06; limited sources and official-source query noted there
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, or materials disclosure was located in the limited official Navy/NARA sources reviewed. The 1941 Navy Filing Manual classifies Calistoga as a ferryboat but contains no asbestos finding; no asbestos presence or absence is established.
