Route AFP Get DOS Name From Entry ID through the existing mars_nwe DOS namespace alias helper instead of returning raw Unix directory entry names from the reverse lookup walk.
WebSDK semantics require this subfunction to return a DOSPathString. The current AFP entry ids are mars_nwe/libatalk metadata ids rather than namspace.c base handles, so the lookup still has to walk the volume tree, but each path component is now formatted with namedos.c build_dos_83_alias(). This keeps the Apple-facing adapter aligned with the existing DOS namespace rules used by normal NetWare clients.
Update the Linux smoke helper's default expectation for raw VOL:PATH smoke inputs to compare against the DOS 8.3 uppercase form. Explicit --expect remains available for callers that want to validate a specific alias.
Tests: git diff --check; gcc -Iinclude -I/mnt/data/stubs -fsyntax-only tests/linux/afp_dos_name_smoke.c
Implement the WebSDK/NWAFP Get DOS Name From Entry ID subfunction (NCP 0x2222/35/18) as a conservative, read-only reverse lookup over mars_nwe's existing volume and AFP metadata infrastructure.
The documented request carries a volume number and 32-bit Macintosh directory entry ID, and the reply returns a length-prefixed DOS path string. mars_nwe's current AFP entry IDs are not the namespace base handles maintained by namspace.c; they are mars_nwe/libatalk AFP metadata IDs cached through nwatalk. Reuse the existing volume table as the search root and nwatalk_get_entry_id() as the identity probe instead of inventing a parallel namespace handle mapping.
The reverse lookup deliberately does not create fallback IDs while walking the volume. It only matches entries that already have mars_nwe or Netatalk AFP metadata, which is the normal smoke-test sequence after Get Entry ID, Get File Information, or Scan File Information has cached the target ID. This keeps the lookup read-only and avoids populating entry-id xattrs across an entire volume as a side effect.
Add a Linux afp_dos_name_smoke helper and wire it into the AFP smoke suite. The helper can resolve the supplied VOL:PATH to an entry ID first, then sends the 0x12 request and verifies the returned path without the volume prefix. The suite continues to exercise the existing path-backed AFP compatibility flow before future create/rename/remove work.
Tests:\n- git diff --check\n- bash -n tests/linux/afp_smoke_suite.sh\n- gcc -Iinclude -I/mnt/data/stubs -fsyntax-only tests/linux/afp_dos_name_smoke.c\n\nTODO:\n- Replace the volume walk with a real CNID/base-ID index when persistent AFP identity storage grows one.\n- Return true DOS 8.3 aliases once the AFP reverse lookup is wired to the namespace alias helpers rather than preserving the cached path component spelling.
