Retrieves the detailed verification results and company profile for a previously
submitted KYB check. Provide the unique id to access the full report,
including registration status, shareholder structure, and official registry data.
Fields present in the response depend on the original check type.

Use this endpoint to poll an Enhanced (Pro) check created with maxLayer greater
than 2: ownership traversal runs asynchronously, so the check stays
IN_PROGRESS until every layer has been resolved. Once COMPLETED,
officersInfos / shareholdersInfos hold the flattened registers of the whole
tree, each entry tagged with layer and parentNode, and registrationInfos holds
one entry per company in the tree.

Enhanced (Pro) checks return registrationInfos (a list) plus layerCalls, the count
of billable registry vendor calls the check consumed, split into live and cache.
Standard checks return a single registrationInfo object and no layerCalls.
