libSceImeBackend technical debt

Unknown function info

• sceImeBackendParamInit (libSceImeBackend) - the layout of the 40-byte parameter block is unknown. It follows firmware 13.42's libSceImeBackend.sprx, read from its disassembly and run natively on x86-64 (not a console): it takes one pointer and returns nothing; a null pointer is ignored; otherwise it writes 0xFFFFFFFF as a 32-bit value at byte 0, clears bytes 4 to 39 and leaves later bytes unchanged
• sceImeBackendOpen, sceImeBackendClose, sceImeBackendReset, sceImeBackendGetStatus, sceImeBackendEnterCharacter, sceImeBackendBackspaceCharacter, sceImeBackendPartConfirm, sceImeBackendAllConfirm, sceImeBackendAllDeleteConvertString, sceImeBackendConvertForward, sceImeBackendConvertBackward, sceImeBackendConvertCancel, sceImeBackendGetString, sceImeBackendGetConvertString, sceImeBackendGetConfirmString, sceImeBackendGetCaretIndex, sceImeBackendModeCaretNext, sceImeBackendModeCaretPrevious, sceImeBackendGetCandidateList, sceImeBackendGetCandidateListSize, sceImeBackendGetCandidateSelect (libSceImeBackend) - declared without parameters: their signatures and behaviour are not established, so every call throws. PPSA05110 imports them and does not load without them.
• sceImeBackendGetConvertMode, sceImeBackendTemporalConfirm, sceImeBackendSetConvertMode, sceImeBackendForTestFunction and sceImeBackendDeleteCharacter (libSceImeBackend) - parameter lists, return types and behaviour are unverified, so every entry throws through NotImplemented_nid_no_patch; the parameterless int declarations only resolve imports. The names and NIDs come from the PS5 13.60 export inventory, and the pinned module map assigns them to libSceImeBackend.
