Reincarnation chains, shared-VIN links, common domains and officers, and owner-group affiliations — the chameleon / double-broker signals that name-and-USDOT lookups miss.

No shared-identity links detected — no reincarnation flag, shared trucks, registration domain, or officer overlap with other carriers.
