Record the successful Linux AFP smoke-suite run for the WebSDK Backup Date/Time Set File Information field. The smoke output confirms bitmap 0x2000, the AFP backup timestamp value derived from epoch 1700000000, and the corresponding mars_nwe archive metadata xattr.
This documents the intended split between the Archive file attribute, which is mapped through the existing NetWare attribute path, and the Backup Date/Time field, which is routed through nwarchive.c and stored in org.mars-nwe.netware.archive.
Tested-by: ./afp_smoke_suite.sh ... --backup-time-only --backup-time-epoch 1700000000 (reported failures=0)
Implement the WebSDK AFP Set File Information Backup Date/Time request bitmap as a narrow metadata write that reuses mars_nwe's existing archive metadata helper instead of adding a new AFP-specific storage path.
The AFP Attributes word already maps Archive through the NetWare FILE_ATTR_A path; Backup Date/Time is a separate SetInfo field and belongs in the existing nwarchive.c archive date/time metadata. Include nwarchive.h in nwconn, fill the AFP information record's Backup Date/Time fields from mars_nwe_get_archive_info(), and accept the SetInfo 0x2000 bitmap by calling mars_nwe_set_archive_info() after the normal AFP path resolution and Modify-rights gate.
Extend the Linux Set File Information smoke helper with --backup-time-epoch/--backup-time-only, verify the returned 120-byte file information record at offsets 28/30, and have afp_smoke_suite.sh dump user.org.mars-nwe.netware.archive so reports prove that the WebSDK field is stored through the NetWare archive metadata path.
Tests: git diff --check; bash -n tests/linux/afp_smoke_suite.sh; gcc -Iinclude -I/mnt/data/stubs -fsyntax-only tests/linux/afp_set_file_info_smoke.c
The AFP Set/Get File Information attribute path now follows the WebSDK attribute word instead of the earlier low-bit smoke placeholders. Hidden, System, and Archive are mapped through the existing NetWare attribute store as FILE_ATTR_H, FILE_ATTR_S, and FILE_ATTR_A, while FinderInfo and Entry-ID remain AFP-specific metadata.
Record the runtime smoke result that verified the corrected bit layout. The suite reports failures=0, exercises Hidden, System, and Archive set/clear with the documented 0x0200, 0x0400, and 0x2000 attribute bits, and confirms the SetInfo request bitmaps 0x0100 Attributes, 0x1000 Modify Date/Time, and 0x4000 FinderInfo.
Also document that user.org.mars-nwe.afp.attributes may legitimately be absent after this mapping: the tested attribute bits are no longer stored as AFP-only xattrs, so ENODATA in the optional xattr dump is expected when no AFP-only bits remain set.
Test status: based on the provided mars-afp-smoke report from 2026-05-30 18:04:21, which completed with failures=0 and preserved the expected FinderInfo, Entry-ID, Modify timestamp, DOS-name, Open Fork, SetInfo, and rights-negative coverage.
