v0.5.0: slice 5 Phase B — the host-root surface (mounts + SMART + grow + destructive gate)
The privileged write surface, isolated behind a narrow, arg-validated, adversarially-
tested seam (HostOps), the same discipline as the slice-4 gate. Completes slice 5.
- internal/storage: HostOps seam + SudoHostOps (systemd .mount units by fs-UUID, detach,
SMART, lvs) via sudoers allowlist + fixed arg vectors, no shell; NoopHostOps fallback.
- validate.go: strict UUID/mount-path/device/LVM validators + in-process systemd-escape.
Headline test: adversarial matrix (metacharacters/traversal/malformed) refused with
zero exec.
- smart.go: smartctl SATA + NVMe parse, UNKNOWN-degrade; lvs thin-pool metadata fill.
- observer enrichment (Observe only): fills smart + thin-pool metadata.
- watchdog: benign re-mount response off the poll path (DevicePresent probe, rate-limited).
- reconcile: ActionResize (benign, grow-only) + proxmox.ResizeLXC; destructive storage ops
(ClassStorageWipe/Decommission) through the slice-4 gate, target-scoped; built+tested,
inert live.
- --selftest=storage [-watch] live harness; configs/felhom-agent.sudoers; privileged.* knobs.
