admin 027948bf3f pbs: namespace-aware client for per-customer offsite tenancy (S4)
Phase-1 live probe (felhom-hetzner) proved backup/restore/list/isolation over
the tunnel with a per-customer DatastoreBackup token, but the agent's PBS client
was namespace-unaware: Snapshots hit the datastore root (403 for a scoped token)
and Verify was whole-datastore (needs Datastore.Verify ~ admin). Operator-
approved fix.

- pbs.Config.Namespace + Client.namespace; Snapshots appends ?ns=; Verify sends
  ns= (ns-scoped verify works with DatastoreBackup on the own ns — no admin
  widening, Phase-1 confirmed). Root-ns clients unchanged (whole-datastore).
- proxmox.Storage.Namespace (parsed from /storage `namespace`).
- pbsTargetsFromPVE threads s.Namespace into the client.

Confirmed tenant ACL: DatastoreBackup on /datastore/felhom-offsite/<ns> (NOT
/ns/<ns>) to BOTH felhom@pbs (user) AND felhom@pbs!<ns> (token) — PBS privsep =
intersection; isolation holds (cross-ns 403 proven). TestClient_NamespaceScoping
red-proofed.

admin 734f45c422 wgtunnel: v4-pin + re-resolve watchdog; FELHOM_WG Critical flips (S4 agent half)
v4-pin (doc 06 §4.2): renderConf takes a pre-resolved IPv4 literal and writes
Endpoint=<ip>:<port> — never the DNS name, never AAAA. Resolver seam (A records
only, LookupNetIP "ip4"); multiple A → lowest (deterministic fleet-wide);
renderConf stays pure. Resolved IP cached: steady-state Apply = zero DNS + zero
execs. DNS failure keeps the last conf (never a teardown).

Watchdog (loop-only, so Apply's zero-exec steady state is untouched): handshake
age > wg_tunnel.stale_after_seconds (default 180) → re-resolve; IP changed →
re-render + restart (endpoint re-IP recovery); IP same → no churn (throttled
warn). Staleness read reuses wg show latest-handshakes (never dump).

Capability: wg-conf-install/enable/restart/handshake-read flipped Critical=true
(backups ride the tunnel from S4); apt-install + disable stay non-critical.
TestWGCapabilityCriticality pins the set.

Tests + red-proofs a/b/d all fire. No new sudoers grant; no wire/JSON change.

staleLockController.Guests() = ListLXC ∩ GET /pools/felhom members (ownership
PROVEN via the pool registry, never assumed from enumeration scope); pool-read

admin b9356d60ab v0.60.0: proof-of-launch destroy gating (F1a/b/c) + restore-test band-advance (F2)
Campaign pool-effects F1 (HIGH): the bring-up compensating rollback and the
restore-test teardown destroyed the target vmid even when RestoreLXC failed
synchronously without creating anything — destroying a guest the transaction
never made (only the pool ACL 403 contained it). A RestoreLXC UPID is now the
sole destroy authorization in all three destroy paths (in-process bring-up
defer, in-process restore-test teardown, Recover). F2: the restore-test
advances past an 'already exists' band vmid (invisible squatter) instead of
failing + false-alerting; a fully-occupied band Skips.

Red-proof verified: with the gates reverted, the four new tests fail with the
innocent-guest destroy. go build/vet/test clean.

buildLocalAPIServer never passed Options.HostReader, so s.host was nil — the

admin 67e2144f11 v0.57.0: re-assert a raw drive's guest-bind (ReassertGuestBinds mount-table fallback)
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.

admin e593fb277a v0.56.0: resolve a raw enrolled drive's durable-id from the mount table
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.

admin 52098302ab v0.54.0: format-safety foundation — unclaimed-disk guard + guarded-mkfs wrapper
Impl-1. Format now runs a mandatory unclaimed-disk guard (internal/storage/claim.go:
SystemDisks + lsblk member-FSTYPE + foreign-mount + RO + pvs/zpool; fail-safe →
CLAIMED) before any mkfs — refuses the OS disk / LVM PV / ZFS-mdraid member /
foreign-mounted device even when non-data-bearing (guard sits in Format, not the
handler). Below the agent, mkfs goes ONLY through configs/felhom-mkfs-guarded.sh
(sudoers no longer allowlists raw mkfs.*), which re-checks the catastrophic cases
as root. Read-only pvs/zpool added to FELHOM_DISK. Tests + red-proof; capability
manifest updated. go build/vet/test clean.

RestoreLXCOptions.Pool → pct restore --pool (omit-when-empty). New
reconcile.DefaultPool="felhom"; BringUpSpec.Pool threaded to the bring-up
restore; BOTH restore sites pool the guest (provision/DR via spec.Pool set to
DefaultPool by the CLI; restore-test scratch via DefaultPool = SPIKE residual

The preventive counterpart to host_disk + storage_fill detectors: the periodic local
whole-guest vzdump now prunes its own old archives (keep-last=3, clamped >=1) so a box
can't refill its own root via its own backups. Local target only — PBS never pruned
(resolved via ListStorage; fail-safe skip on unknown). Seeded in host-install.

admin 6e38e2f921 agent v0.49.0: reboot-during-backup stale-lock recovery (F2-b) + shared-parent script redeploy fix (F2-a)
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.

The golden bakes --onboot 0 (template safety) and the back-half never overrode it, so every

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

zero controller change (it already auto-discovers <sys_drive>/felhom-data and
warns via system.IsMountPoint; the mp reaches the container via the existing
-v /mnt:/mnt:rslave bind).

- build-golden.sh: --mp1 ...,mp=/mnt/sys_drive,backup=1 (env GOLDEN_SYSDATA_GB=8);
  findmnt /mnt/sys_drive separate-mount guard + vzdump aborts if mp0 OR mp1 excluded.

  new "4c" online grow-only block mirroring the "4b" Docker-data grow.
- main.go: -sysdata-grow / -sysdata-mount flags wired into all three call sites.
- Tests: SysDataGrow (asserts ResizeLXC mp1 +42G) + SysDataGrowZeroNoResize.
- RUNBOOK extended to the three-volume layout (32 rootfs + 200 docker + 50 user-data).

Static CT volume, NOT an enrolled drive — never enrolls/ejects/decommissions.

admin fbe113011d v0.39.0 — DR-recipe completion: live PBS coord + drop role/restic_repo_coord from v1 drive shape
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).

Tests: live_reporter_test.go (T1 load-bearing coord-without-verify + T2..T6),
TestDRRecipeHostHalf_V1DriveShape; each companion demonstrated to fail pre-fix then
reverted. go build/vet/test green.

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.

admin a621f4c5a0 agent v0.37.0: host-reboot remount re-resolves enrolled drives by fs-UUID
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.

make-private+make-shared only when first creating the self-bind; re-running it

The self-bind inherited /'s shared peer group, so binds under /mnt/felhom-drives
propagated back and doubled. make-private (own group) before make-shared fixes it.

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.

admin a2374ca679 agent v0.35.1: shared-parent unit runs before pve-guests on host boot
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.

admin 26c6d1e4d1 agent v0.35.0: intermediary mount — guest-reboot re-propagation (load-bearing)
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.

admin 3a9be73875 agent v0.34.0: intermediary mount model — shared parent + host-side attach/detach + reconcile
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).

admin 4777f8a221 F20-BUG3: run mkfs detached (survives request deadline + agent restart); v0.31.0
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.

admin 4cd1d024e9 F9: auto-re-assert enrolled guest data-drive binds on agent startup
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.
