Auto-scan every inbound file for malware with Windows Defender — the Defender sibling of clamav-scan, for a Windows-hosted recued server. Installs one reactive recipe that fires on data.file.received.*.created (an inbound reception drop, messenger media, or mail attachment), runs the Defender pack's file.scan over the bytes, and writes the verdict (clean / flagged) back to the record's scan_status. This sharpens the reception attachment scan-gate (D-173 P5): a flagged upload surfaces a stronger warning when the reviewer approves the held request, while a clean one clears the advisory. Depends on the Windows Defender capability pack (defender-pack), which carries the cli scan op and the MpCmdRun / elevation / Windows-only setup docs; install both on a Windows server running elevated. An MpCmdRun exit-2 result (a threat, or a scan error such as a non-elevated run) is conservatively flagged for review (fail-safe — no malware passes); a launch failure, timeout, or any other exit code leaves scan_status untouched (unscanned, the advisory gate still warns) rather than flagged. After install, the default dish runs on every inbound file; no per-file configuration. Install EITHER this or clamav-scan for your platform — not both.
