+- Lands in `/mnt/disks/WSD2L840/git/` — an **Unassigned Device** (external
+  disk, not part of the protected array), not the RAM-backed root — keeps
+  the last 30 locally, deeper history than alpha's own 14, given the
+  disk's ample headroom.
+- **The device isn't guaranteed to already be mounted** when the script
+  runs, so it resolves the disk by filesystem label (`findfs
+  LABEL=WSD2L840`, not a hardcoded `/dev/sdX` — USB/Unassigned-Device
+  paths aren't stable across reboots) and mounts it itself via the
+  Unassigned Devices plugin's own `rc.unassigned mount` (confirmed
+  idempotent — safe to call even when already mounted). Explicitly
+  verifies the result is a real mountpoint (`mountpoint -q`) before writing
+  anything — refuses to run rather than risk silently dumping backups onto
+  the array if the disk is unplugged or fails to mount.
