Implements SPIKE-smart-coverage-2026-07-25 fixes B+A (additive; MinAgent unchanged).
Fix B: storage.SmartReader.SMARTForBacking wired into the /disks union path (localapi
Smart seam) so registry/USB drives get a real SMART read (watchdog Known stays
enrich-free). Fix A: smartDeviceFor resolves dm/LVM to the whole disk via
/sys/block/<dm>/slaves (recursive; skips >1-disk); the builtin local dir on the LVM
root gets a SMART-only device from its containing filesystem (never touches
backing/durable_id). SmartSummary.ModelName captured from smartctl. Fix C (-d sat)
stays rejected. Tests + red-proofs (dm multi-disk skip, enrich smartHint, union
routing); Known-path-never-SMARTs asserted.
Additive, backward-compatible (MinAgent floor unchanged). The SMART is already
computed on the request path (storage.Observe -> enrich); this copies the target's
Smart into localapi.DiskInfo (pointer, omitempty) only when Health != "", so an
unread/absent summary stays omitted and the controller renders "Nincs adat".
No new smartctl load, endpoint, or sudoers change.
Test TestDisks_SmartSerialized + red-proof (drop the copy -> fails).
roleForMountPath resolved role only from the PVE storage view; a bind-mounted
RAW enrolled user-data drive is not a PVE storage, so it fail-safe'd to system
and the eject/decommission gates 403'd EVERY user-data drive in the standard
topology (campaign F2, where=/mnt/teszt_enroll role=system). Add a mount-table
fallback mirroring durableIDForMount Impl-2b: device-keyed classification with a
whole-disk containment pass (new storage.SameWholeDisk) and the Observe-error
early return kept BEFORE the fallback (else a blind view -> permissive). Only
roleForMountPath touched. Tests A1/B1/B2/C1-C3 + 3 red-proofs; existing RoleGated
tests green unmodified.

From AUDIT-blast-radius-hostroot-localapi-2026-07-02.md. Each fix ships with a
non-hollow test + a companion red-proof (shown failing on the pre-fix impl).
Sudoers install-source grants became globs — deploy the sudoers drop-in with
the binary. A1 (stale-lock pool-membership) deliberately excluded (spike).

Use ResolveStorageDevice (EvalSymlinks) so a registry drive shows /dev/sdd, not
the /dev/disk/by-uuid/<uuid> symlink path — matching Observe-sourced rows.

Agent-view showed "—" device + no size for a raw (no-PVE-storage) drive because
the registry union row never set backing_device/total_bytes/used_bytes (Observe
drives get those from pvesm status). Resolve BackingDevice via ByUUIDDevicePath +
read capacity via statfsCapacity (build-tagged syscall.Statfs; no-op off-Linux).

The Impl-2a registry union row omitted GuestPath + BoundUnderParent, so the
controller read a registry-only (raw) drive as "Leválasztva" despite being mounted
+ bound live. Populate them like the Observe path (StablePathForRaw +
boundUnderParent). Last piece of first-class raw-drive support.

ReassertGuestBinds mapped durable-id->mount from Observe() only, so a raw enrolled
drive was never found and its in-guest bind wasn't re-asserted after reboot/re-mount
(drive showed "Leválasztva"). Augment the map from the mount table (raw /mnt/<name>
-> device fs-UUID via HostReader), skipping the /mnt/felhom-drives bind; Observe
failure no longer aborts. Completes v0.56.0's raw-drive durability.

durableIDForMount was Observe-only, so a raw (non-PVE-storage) drive's enroll
intent + guest-bind went unrecorded ("durable-id unresolved") — it mounted+bound
but wasn't intent-tracked (RegistryKnownTargets skips intent==new). Fall back to
resolving the mount's device fs-UUID (HostReader.Mounts + ResolveUUID) →
uuid:<fs-uuid>, same scheme as Observe. Test + red-proof. Residual:
ReassertGuestBinds still Observe-based (raw guest-bind not re-asserted post-reboot).

GET /disks/candidates enumerates host disks the Impl-1 unclaimed filter proves
free (init/attach split). RegistryKnownTargets sources the watchdog's known-drive
set from the intent registry + Felhom .mount units (not Observe/PVE storages) —
decouples drive health from PVE storage (closes the registry-only false-detach
class); Observe kept for real PVE storages + a deduped /disks union. Idempotent
existing-drive migration at start. Tests + red-proof (Observe misses a
registry-only drive; registry provider tracks it). go build/vet/test clean.

Eject now DetachDrive's the bind under the parent but leaves the raw /mnt/<name>
mounted, so disconnect->reconnect re-binds on a non-removable drive. Tests updated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The decommission unmounted the raw /mnt/<name>, orphaning a non-removable drive
so re-enroll bound an empty dir. Now DetachDrive only (bind under parent); raw
stays mounted so re-enroll re-binds. Test: raw NOT unmounted + DetachDrive called.

GET /disks emits guest_boot_id = <host-btime>-<guest-init-starttime>: changes on
every guest/host boot, stable across controller-only restarts. The controller
persists it + deterministically recreates drive-backed apps on change (replaces
the timed state-sample). Non-hollow parser test + companion.

A guest's parent bind is non-recursive, so a guest reboot leaves enrolled drives
bound on the HOST but invisible in the fresh guest ns (propagation only delivers
new events). AttachDrive(vmid) now checks GuestSeesMount (/proc/<pid>/mountinfo)
and force re-binds (umount+mount) to re-propagate; a 20s periodic reconcile
self-heals guest reboots without an agent restart; BoundUnderParent reflects guest
visibility (the controller gate's signal). Caught + fixed in the live migration.

Replaces the per-drive 'pct set -mpN' bind with ONE permanent parent bind
/mnt/felhom-drives plus host-side felhom-data swaps underneath it (propagates
into the running guest live, no pct, no reboot; C1-immune; confined; fail-closed
when absent). EnsureSharedParent installs a boot unit ordered Before=pve-guests.
ReassertGuestBinds is now a pure host-side reconcile. /disks reports GuestPath +
BoundUnderParent for the controller repoint+gate. Non-hollow tests + companions.

Pre-start PVE hookscript (internal/guesthook) creates host-root placeholders for
absent bind-mount sources so the guest always boots (fail-closed); decommission
now pct set --delete's the dead mp (GuestBinder.DetachBind) so a missing source
can't brick the next reboot (B3 C1 bug). Non-hollow tests + companions. Installed
+ registered per-guest by the provision back-half. Transitional ahead of the
intermediary-mount re-architecture which makes C1 structural.

POST /disks/decommission mirrors eject (withGuest, user-data role gate) — no
operator signature, non-destructive (never formats): sets IntentDecommissioned,
prunes the GuestBindStore entry, unmounts. ReassertGuestBinds is now intent-aware
(skip non-enrolled) so a decommissioned-but-present drive never auto-rebinds on
agent restart — the load-bearing F9-reconnect fix. GuestBindStore.Remove added.
Operator-signed DecommissionExecutor + classify untouched. Non-hollow tests incl.
the intent-aware reassert companion (mutation-proven to fail on intent-blind code).

The format ran mkfs under the HTTP request context, so the controller's 15s client
timeout cancelled it → SIGKILL mid-write → corrupt disk. Now mkfs runs DETACHED off
s.baseCtx (a dropped request can't kill it) via a persisted formatJob record; the handler
still waits to return the synchronous result (backward-compatible with the v0.62.0
controller) but abandoning the wait on client-disconnect leaves the mkfs running to
completion. New GET /disks/format/status surfaces the job (additive). RecoverFormatJob
runs on agent startup: a record left 'running' (agent died mid-format) is re-resolved by
durable-id (anti-retarget — absent/swapped disk NOT re-formatted) and the mkfs re-run; a
blank/path-bound interrupted format is marked failed (retry), never auto-re-run.
Tests: detached run persists running→done + binds durable-id; status endpoint; recovery
re-runs an interrupted durable-id-bound format; skips blank; skips unresolvable durable-id.
Version 0.30.0 → 0.31.0.
The in-guest bind (pct set -mpN) is config state that a destroy+re-provision drops, and
nothing restored it — so a re-provisioned guest came up with its enrolled HDD unattached
(the live-drive F9 finding). New GuestBindStore persists, per guest, the durable-ids of
enrolled drives (recorded at guest-attach); ReassertGuestBinds runs on agent startup (the
host's bring-up/reconcile trigger) and re-adds any bind a guest is MISSING — but ONLY when
the durable-id still resolves to a present, mounted drive (a swapped/absent drive is never
auto-bound) and the guest lacks it (idempotent). The re-added bind activates on the guest's
next reboot, like the enroll flow. Wired in main.go (store opened beside drive-intents.json;
ReassertGuestBinds called before the local API serves).
Tests: restores a missing bind with no manual call (the operator's real-trigger proof);
skips absent/swapped durable-id; no-op when already bound; store survives reopen (restart).
F20-BUG2: the /disks list only carried DurableID in the uuid: scheme (for /disks/assign),
but the wipe gate resolves devices in the byid:/byuuid: scheme — so a customer confirming a
wipe with the advertised id was refused (binding_mismatch). Added a shared s.deviceDurableID
seam used by BOTH handleDisks (new DiskInfo.WipeDurableID) and the format gate, so the id the
customer copies from the list is exactly the id the gate accepts. DurableID (uuid:) is unchanged
(still feeds assign).
F9 (reporting half): added DiskInfo.GuestAttached — whether the drive's namespace is actually
bound into THIS guest's config (guestBoundPaths), distinct from mere host presence (State). This
is the signal whose absence made the HDD look available when it wasn't attached, and resolves the
F2 hdd_configured-vs-/disks disagreement.
Tests: wipe_durable_id is the gate scheme + distinct from uuid:; the list's wipe id matches the
gate's device-id binding (no mismatch); guest_attached true iff bound into the guest.
handleDiskFormat's customer-confirmed branch formatted the mutable req.Device
path; the durable id only bound the confirmation, never the mkfs target. A /dev
reassignment between inspect and mkfs could wipe the wrong physical disk.
Now mirrors signedjobs.WipeExecutor: resolve confirmed durable id -> current
device, re-derive + require exact match, re-inspect (still data-bearing), then
format THAT device. Any refusal -> 409, no mkfs. New antiRetargetResolve helper
(injected deps, unit-tested: mismatch/gone/blank/empty all refuse). Injectable
reresolveWipe seam on Server (defaults to real storage funcs).
BRANCH ONLY — pending supervised review/deploy (see AGENT-001-FIX-NOTES.md).

POST /disks/guest-attach binds an enrolled drive's felhom-data namespace into
the guest (Model A: felhom-data is the bind source mounted at /mnt/<name>, so
only Felhom's namespace crosses in). GuestBinder does mkdir+chown(100000)+pct set
(RW bind) via the fenced runner. Idempotent, free-slot selection, path-validated.
Spike-proven on 9201. Pairs with controller P2C + golden /mnt:rslave (P2B).

handleDiskEject now resolves the authoritative role of the storage at `where`
and refuses 403 (no Unmount) unless it is user-data. Fails safe to protected on
ambiguity. Adds roleForMountPath + an injectable HostReader seam for testability.
TestEject_RoleGated asserts protected mounts are refused with no Unmount.

localapi.DiskInfo gains durable_id (from StorageTarget.DurableID, "uuid:<fs-uuid>"
for usb/local-dir). The de-privileged controller can't read a device's fs UUID
but assign mounts strictly by UUID — this read-only field is the only way it
learns the assign key. No new privilege, no gate change.

A destructive op runs ONLY on a pinned-key-verified, nonce-fresh, in-window,
host-bound, durable-id-bound operator signature. New cmd/felhom-opsign signs
canonical OpBlobs offline via ssh-keygen -Y sign (hardware-ready); the signing
key is never in the hub or agent. New internal/signedjobs runner verifies each
queued blob through the gate and only on all-pass runs the WipeExecutor, which
re-resolves the DURABLE device id + re-inspects (8C) before mkfs — closing the
8C data-bearing-wipe pending_signature gap. New storage durable-device
resolution; authz.CanonicalBlob promoted to production. Real-crypto tests assert
valid executes and forged/replay/expired/retarget/non-pinned are rejected
(executor never called).
