F2-b: at startup, recover a guest left with a stale vzdump lock by a
reboot-during-backup — pct unlock -> delete dangling vzdump snapshot ->
start iff onboot, guarded by a no-vzdump-running invariant (fail-safe).
New internal/localapi/stalelock.go; proxmox GuestConfig.Lock()/OnBoot(),
ListSnapshots, ListRunningTasks, Snapshot type. New narrow sudoers grant
FELHOM_STALELOCK (pct unlock) + Critical capability stalelock-unlock.
F2-a: EnsureSharedParent only redeployed the boot script when the UNIT
differed, so the v0.36.6 make-private fix never reached hosts whose unit
was current -> /mnt/felhom-drives stayed in root's shared:1 and doubled
every drive bind. New sharedParentInstallStale compares BOTH script and
unit. Boot-time-only; never churns the live mount.
Both root causes confirmed live on felhom-pve before fixing. Green gate
(build/vet/test) all pass.

New local-API POST /controller/swap (+ GET /controller/swap/status), withGuest-
scoped: the agent records the previous image, confirms the target is present,
rewrites /etc/felhom-controller-image, restarts felhom-controller-bootstrap.service,
verifies the new controller is healthy (docker inspect, <=90s), and ROLLS BACK to
the previous image if not. Single-flight per guest; strict image-ref validation;
crash-safety state file. GuestBinder.GuestExec is the pct-exec seam.

The golden bakes --onboot 0 (template safety) and the back-half never overrode it, so every
provisioned customer guest was onboot:0 -> after a host reboot/power-cut the customer's whole
home-server stayed stopped until a manual pct start. Add a fatal 'pct set <vmid> -onboot 1' step
to BackHalf.Provision (right after the config-mount attach), mirroring the existing pct set ops.
No startup/boot-order: the v0.75 mountpoint-gate covers the drive-bind race at boot.

Extends the OS/Docker-data split to a three-volume layout: rootfs + Docker-data

Live PBS coord: new internal/pbs/live_reporter.go (LiveSnapshotReporter implements
hub.PBSReporter via the cheap Client.Snapshots() list with last-known-good fallback,
bounded by an 8s timeout, list-only — never triggers a verify). Closes the gap where
the recipe's pbs block was omitted whenever the verify-loop SnapshotStore was empty
(one-shot collect + the first ~6h after a daemon restart). SnapshotStore.Get added
(per-datastore LKG). Wired into the collector in both runDaemon and runSelftestHub;
the verify loop keeps Recording into the SAME shared store via one hoisted pbsTargets.
v1 host-half drive shape: dropped drives[].role (hub/operator-owned manifest concept,
not host-derivable) and drives[].restic_repo_coord (named a backup tier that doesn't
exist). Drive shape is now {durable_id, mount_path, intent, fs_type?, total_bytes}.
Hub reads drives as json.RawMessage → no hub struct change; goldens re-pinned
byte-identical (agent + hub copies).

DR recipe slice (agent half), grounded in SPIKE-dr-recipe-2026-06-16. Additive
`dr_recipe` host-report section = the non-secret reconstruction scaffolding the
operator must rebuild before PBS bytes can land. Built by pure
BuildDRRecipeHostHalf from facts the report already collects (no new reads):
guests[] sizing, drives[] (user-data by durable_id/role/mount/intent),
pve_storage[] (storage.cfg), pbs coordinates.
BOUNDARY (Phase-1 lesson): every field is an identifier/intent/size/coordinate —
never a key/password/token/hash/ENC:. PBS key stays in escrow; restic password
stays in escrow; the recipe names only the coordinates the restore targets.
Tests: BuildDRRecipeHostHalf selection, NoPBS, NoSecrets (boundary mirror),
dr_recipe key-set in the cross-repo golden contract test. recipe_version=1,
ignore-unknown on read.

TASK A — close out the reboot story (agent half). Root cause (pinned live on
felhom-pve): an enrolled .mount unit left `disabled` by a prior detach never
auto-mounts at boot, and kernel re-enumeration can move a drive's node
(/dev/sdb->sdc). Fix re-asserts every enrolled mount by filesystem UUID at
startup + on the periodic tick.
- ResolveStorageDevice: resolve uuid:<fs-uuid> -> current /dev node via
/dev/disk/by-uuid (never a cached node); errors if absent.
- parseFelhomMountUnit: pure inverse of renderMountUnit (marker-gated).
- (*SudoHostOps).ReassertEnrolledMounts: re-run EnsureMount (enable --now) for
any enrolled unit not in /proc/mounts; idempotent, skips mounted/absent.
- main.go: runs before ReassertGuestBinds at startup + on the 20s tick.
- tests (Linux, seam=device resolution): letter-move tolerated (sdb->sdc) +
red-proof companion, absent/scheme rejection, render->parse round-trip.
TASK A2 verdict: enrolling a NEW drive does NOT need an LXC restart — the path
lands on the live AttachDrive (shared parent, named live slots), not RebootGuest.

Detach now removes ALL stacked binds at a stable path, not just one layer, so an

Eject now DetachDrive's the bind under the parent but leaves the raw /mnt/<name>

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

GET /disks emits guest_boot_id = <host-btime>-<guest-init-starttime>: changes on

The shared-parent oneshot never ran before pve-guests (WantedBy=multi-user
wasn't pulled into the boot transaction), so on a host reboot the guest bound a
not-yet-shared parent -> private -> propagation broken. Now WantedBy=pve-guests
(pve-guests pulls it in + Before= orders it first); EnsureSharedParent reinstalls
the unit when content differs so the fix deploys.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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).
After a guest DHCP IP move, the split-horizon resolver kept serving the old IP:
the drop-in (address=/domain/ip) updated but 'systemctl reload dnsmasq' (SIGHUP)
does NOT re-read /etc/dnsmasq.d config — only /etc/hosts + cache. Changed
reload() -> restartDnsmasq() so address= changes actually take effect.

A destructive op runs ONLY on a pinned-key-verified, nonce-fresh, in-window,
