internal/storage: mkfs executor (Format, device-pinned, narrow FELHOM_FORMAT sudoers) + data-bearing device inspection (InspectDevice/DeviceProbe via blkid+lsblk; conservative — ambiguous=data-bearing). internal/localapi: /disks (+ data-bearing flag), /disks/assign (EnsureMount), /disks/eject (Unmount + dependent guests), /disks/format. SECURITY CENTERPIECE: the agent inspects the device itself; data-bearing format -> ClassStorageWipe gate -> pending_signature refused; the caller's claim is never trusted. Additive (no controller change yet). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
