Additional callable exports - 19 entries observed in the 3.20 export inventory and present in the later 13.60-labelled inventory are import-resolution declarations only. The later inventory label does not authenticate a retail firmware version. Parameter lists, return types and behavior are unverified; parameterless int declarations are placeholders, not verified ABI contracts. Every entry throws through NotImplemented_nid_no_patch. Unidentified names use literal NID aliases. No runtime functionality is implemented. Identified candidate names match their NIDs in the public symbol database or supplemental catalog.
