RtlUTF8ToUnicodeN and RtlUnicodeToUTF8N are selected unchanged from ReactOS revision 32bb061415f813b6ced25ff91f4d258f33c5191f, sdk/lib/rtl/utf8.c. Its GPL-2.0-or-later notice and COPYING remain beside the source. provenance.json records source and selection hashes for both functions. The native adapter supplies fixed-width types and host buffers; guest memory remains owned and checked by NativeProcess. No upstream process, loader, heap or NLS globals are imported. Product distribution review remains open.
