[4]NHHC DANFS ship classification and steam-era service record, read with the Fletcher-class profile as background [nhhc_danfs]
- Locator
- DANFS opening class/specifications block; Fletcher-class profile used only for background
- Finding type
- asbestos_application
- Finding
- Class/era context only: a World War II Fletcher-class destroyer operated as a steam-powered naval vessel during the period when boiler and steam-line insulation, lagging, gaskets, packing, and fireproofing were common marine applications; these products are not documented as installed aboard DD-656 by the consulted source.

[6]Authenticated CourtListener API v4 sweep via cl-auth-search.py; fleet pacing limiter reported budget spent [court_record]
- Locator
- cl-auth-search.py stderr: fleet-wide pacing budget momentarily spent; exact-name opinion request did not return a usable result
- Finding type
- litigation_documented
- Finding
- No litigation classification was completed because the authenticated helper entered fleet-wide pacing stand-down before usable search results were returned. Exact-name and hull-number litigation status therefore remains unresolved.
