Docker always creates a fresh tmpfs at /dev, silently dropping any /dev:/dev bind mount. Block devices must be accessed via /host-dev where the host /dev is actually mounted. Changes: - docker-compose.yml: /dev:/dev → /dev:/host-dev:rw - safety.go: add HostDevPath constant + HostDevicePath() helper - format_linux.go: all device ops (stat, sfdisk, partprobe, mkfs.ext4, blkid) use HostDevicePath() to resolve /dev/sdb → /host-dev/sdb - safety_linux.go: IsSystemDisk() stats device via /host-dev - scan_linux.go: enrichWithBlkid() probes each partition individually via /host-dev/sdXN instead of batch blkid -o export (which can't find devices when /dev is Docker's minimal tmpfs) Fixes "stat /dev/sdb: no such file or directory" in FormatAndMount.
