    "Each vessel is placed in its DEEPEST stage of GLEIF resolution: no owner resolved in the GLEIF LEI register; a registered owner identified (a GLEIF legal entity) but with no onward corporate parent; or a corporate parent resolved in the GLEIF chain. This measures traceability via the GLEIF Global LEI Index specifically — a vessel with no GLEIF match may still have a registered owner in other records (a flag registry or commercial database), so \"no GLEIF-resolved owner\" means not traceable in the public LEI register, not necessarily ownerless.",
    "GLEIF resolves the corporate parent / consolidating entity, NOT the AML ultimate beneficial owner (the natural person who ultimately owns or controls the entity). So \"corporate parent resolved\" is still not a verified beneficial owner — and for the sanctioned fleet you usually cannot get even that far. GLEIF parent-chain coverage is sparse generally, so this measures public-record traceability, not necessarily true corporate structure.",
    "Distinct from the ownership-opacity dataset (which scores opacity risk LOW / MEDIUM / HIGH): this one measures how far the ownership can be RESOLVED in public records, not how risky a resolved owner is."
