- Limitations
- A failure to locate a public record is not proof that asbestos was absent. Firecrawl access was quota-blocked; authenticated CourtListener search was suspended by a multi-hour daily-quota wait before the exact-name and hull-number sweep was completed. See report and search ledger. This row does not characterize uncompleted queries as no-result findings.
