[2]NavSource Online, Submarine Chaser Photo Archive, SC-524 (live page verified by direct fetch) [other_primary]

- SC-524 page, construction/service bullet list
- Finding type
- vessel_history
- Finding
- SC-524 is an SC-497-class submarine chaser built by Mathis Yacht Building Co., Camden, New Jersey (YN 251). NavSource gives the order date as 1 April 1941, keel date as 29 May 1941, launch date as 19 September 1941, and a 13 April 1942 commissioning entry. Its page also carries an ex-PC-524/PC-524 label, but the batch re-scope corrects that stale designation: PC-524 never existed as a PC vessel, so this record uses USS SC-524 and does not adopt the PC designation.

- GAO product page HRD-80-2

- Population
- Navy shipyard workers and Navy asbestos program
- Limitations
- Program-level context only. It cannot support a ship-specific finding, product identification, individual exposure, quantity, remaining material, causation, or legal eligibility; the public product page was verified live but the full report text was not extracted in this session.

[7]CourtListener authenticated helper sweep: four required base queries attempted; one docket query returned a 20-result page with 1,517 total matches, and the other three requests returned no payload after the helper request wait [other_primary]
- Locator
- CourtListener helper outputs /tmp/sc524-name-docket.json and unavailable payloads for the other three required requests
- Finding type
- litigation_documented
- Finding
- No qualifying asbestos-litigation hit was identified in the returned CourtListener docket page: all 20 displayed results were unrelated litigation or name collisions, including one asbestos MDL docket whose returned metadata did not identify SC-524 as an exposure site. The opinion and hull-number request payloads were unavailable after the helper wait, so the litigation sweep is incomplete rather than a clean zero-result finding.

- CourtListener indexed dockets/opinions
- Limitations
- Do not treat this as proof that no asbestos case names SC-524. The base docket query overflowed and the other three helper responses were unavailable; no blind variant was run because the helper sweep was incomplete and the name-number collision behavior was unresolved.
