libSceNpTcs technical debt

sceNpTcsIntDownloadData, sceNpTcsIntUploadDataToNewSlotAbort and sceNpTcsIntUploadDataToNewSlotBegin (libSceNpTcs) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
Older callable NIDs: 8 unidentified exports have unverified names, signatures and behavior. These are throwing import-resolution placeholders; no functionality is implemented. No matching NIDs were found in the later module inventory.
