Config-only (wrapper + red-proof); the Go binary is unchanged, so this ships
with the next agent deploy as a config artifact.
The reconcile verb built `args=(--server "$server" --fingerprint "$fp")`. PVE
treats a PBS storage's `server` as a CREATE-ONLY parameter and rejects the
ENTIRE `pvesm set` call — "can't change value of fixed parameter 'server'" —
even when the value passed is byte-identical to the stored one. So reconcile
could never succeed against an existing entry; it exited 255 every time.
That is severe rather than cosmetic because the agent consumes the hub's
ONE-TIME PBS token secret BEFORE invoking the wrapper. Each hub "Re-issue PBS
credentials" therefore minted a secret, the agent burned it, the wrapper
rejected the apply, and the entry stayed pinned to the revoked credential —
a PBS DR tier authenticating 401 indefinitely while the agent reported
`pbsdr: converged state=applied`.
Live-diagnosed on the N100 during the rehearsal wrap (felhom.eu
tests/VALIDATION-n100-rehearsal-2026-07-18.md F2, ROADMAP R-39). Proven on the
live entry before writing code: `pvesm set <id> --server <same> --fingerprint
<same>` -> rejected; the same call without --server -> rc 0. K (<id>.enc) and
the .pw store verified byte-untouched after the rejected call — PVE rejects
atomically, so the set-only law held.
Fix: drop --server. The server address is immutable by construction (relocating
a PBS endpoint needs a fresh create), so there was never anything to reconcile
there. --fingerprint (+ --password when a secret is fed) remain.
Red-proof TestReconcileNeverPassesServerToPvesmSet: isolates the reconcile)
block from the shipped wrapper, asserts no --server reaches `pvesm set` and
that --fingerprint is still pushed. Verified RED on the unfixed wrapper, GREEN
after. Handles two vacuous-pass traps that both fired while authoring it: the
pattern is line-ending tolerant (\r?\n — this repo is cloned on Windows, and an
\n-only pattern matches nothing and passes silently), and comment lines are
stripped before matching (the WHY note quotes the very flag under test).
NOT fixed here, both still open and riding the spec'd R-39 agent train:
1. R-39's primary half — the agent re-applies on a change of the DESCRIPTOR
HASH (manager.go ~L235), but a credential re-issue leaves the descriptor
byte-identical (same token_id/fingerprint; only the side-table secret
rotates) and bumps only the generation, so a converged agent still ignores
a fresh secret. This makes the apply succeed once it re-applies; it does
not make it re-apply.
2. The verify loop reads /etc/pve/priv/storage/<id>.pw directly as non-root —
a path it can only ever WRITE through the root wrapper (0700 root:www-data;
sudoers exposes create|reconcile|grant, no read verb), so it is permanently
blind to the failure it exists to catch.
Demo box: wrapper hotfixed in place (.bak-20260718-preR39 kept). NOT yet healed
— diagnosis consumed the pending secret against the unfixed wrapper; the agent
parked correctly in consumed-failed (no burn loop). Healing needs Viktor to
click "Re-issue PBS credentials"; the agent will then pick it up unaided
(marker.json absent, so the L235 short-circuit does not apply).

MinAgent coupling: felhom-controller v0.143.0 gates its guest-memory-resize UI on
this agent (FeatureGuestMemoryResize, MinAgent 0.90.0).
R-24 guest RAM resize (internal/localapi/guestmemory.go): self-scoped GET/POST
/guest/memory. Agent enforces every bound FRESH per request (min 2048, max
host_total-2048, shrink floor max(2048, usage+512)); applies via PVE SetConfig —
live cgroup apply, no reboot (Phase-0 proven on the nested demo box). Verify-after-apply
re-reads maxmem before claiming success. New narrow MemoryOps seam (GuestAPI untouched);
Options.Memory nil -> 503. Memory only.
R-28 fast-tick (internal/fasttick): while any desired-state item is unapplied -
including the pre-tunnel window a hub poke can't reach - pulse the shared out-of-band
trigger every 30s, self-disarm on convergence. Four cached sources (desired-gen==0,
reconcile Planned-Pending>0, pbsdr waiting_secret only, wgtunnel desired-not-operational);
LOUD pbsdr states + pending_signature excluded. Seams: reconcile.Engine.LastResult() +
wgtunnel.Manager.TunnelConvergence() (cached, no per-tick exec).
Guests-0/0: hypothesis REFUTED live (9201 IS a pool member; 0/0 was the pre-provision
window; PoolAddVMID re-assert already covers restore-over-existing). No code change; the
fast-tick mitigates the window.
Tests + red-proofs (i floor guard, ii max guard, iii always-pulse) all restored green.
- pbsdr: on a 403 pre-check (non-default storage id, no ACL yet) self-grant via the root wrapper then re-read, instead of aborting before the grant — closes F4/R-22. Red-proof TestSelfGrant_PreCheck403DoesNotAbortBeforeGrant.
- escrow preflight: late-bound CurrentPBSStorageID re-reads agent.json so a pbsdr-seeded pbs_storage_id flips the row green in-process (no restart). Red-proof TestEscrowPreflight_PBSStorageIDLiveReload.
- internal/poke: contentless UDP poke listener bound exclusively to the box WG /32 (port 51822), leading-edge debounced, fires the hub-loop out-of-band trigger for an immediate desired-state cycle. First slice of R-13. Red-proofs TestBindConfinement + TestDebounceCoalescesBurst.
Operator ruling 2026-07-13: walk the root's backing device through /sys/block/<dev>/slaves
recursively down to physical disks (dm AND md; topology, never VG names); those + any mounted-ESP
holder are system; the all-system fail-safe returns to being the WALK-FAILURE error case only.
SAFETY DIRECTION: a root-backing disk classified candidate is made impossible — per-branch
conservatism (any unresolvable slave fails the WHOLE walk -> ok=false -> the unchanged all-system
path).
- physicalDisksOf/walkSlaves in role.go (symlink canon -> wholeDiskOf fast path -> recursive
slaves walk; cycle/depth guard; non-/dev sources unwalkable)
- HostReader.BlockSlaves(name) — the ONE new seam method; ProcHostReader reads
/sys/block/<name>/slaves; all four test fakes mirror it
- role_walk_test.go: signature table (root-backing disk ALWAYS system across legacy-LVM /
md-raid / EFI+raw / EFI+LVM / nested dm-on-md — NEVER weaken) + dead-wizard-lives +
dangling-slave fail-safe (real sysKnown=false path) + cycle + empty-slaves; red-proofs A/B/D
run->fail->revert (recorded in REPORT)
- §3 spike transcripts (drill legacy: dm-1->sda3->sda; felhom-pve: ESP+walk agree on sda ->
byte-identical regression); caller audit: none relied on all-system as a feature
- format/mkfs paths, data-bearing guards, wizard UI untouched
Agent half of the verify-before-commit task (SPIKE-nas-verify-2026-07-11, b57f6c1):
retry=0 in the production NFS options (Q4-vi); ClassifyNetVerifyFailure on the live

pre-probe, nothing installed) + detached in-memory verify job judging /proc/mounts

The live scratch DR exposed the second half of PVE's all-or-nothing
explicit-params restore: mountpoints NOT named in the params are silently
DROPPED - the DR guest came up without its mp0/mp1 data volumes (boot

derives the COMPLETE param set from the archive's extracted config:
explicit rootfs, every storage-backed mpN passed through (size + in-guest
path + backup flag preserved so vzrestore extracts its content), the two
structural binds replaced by 4d-swapped throwaways; unknown bind mpN or
unparseable size refuses loudly. Snapshot sections never shadow the

Pool membership is what lets the pool-scoped token reach a guest; pct restore
--pool sets it only at CREATE, so a restore over an existing VMID drops the guest
from the felhom pool and 403s the next restore-test/DR on VM.Audit. This empty-pool
state is the true root cause of the campaign's "R1" (bind-mount restore failing was
a symptom — restore-test's existing bind neutralization never ran without config-read).
Add Client.PoolAddVMID (PUT /pools, additive+idempotent, Pool.Allocate) and call it
in bring-up after liveness when spec.Pool!="" — warn-not-fail on a hiccup (liveness
wins). B3 scratch-teardown 403 diagnosed as a cascade (restoretest already passes

A WAN (pbs-tier) restore of a large guest exceeds the restore-task wait's 10m
default → the wait expired mid-restore, teardown fired against a still-restoring
(not-yet-pool-associated) scratch guest → leak + a phantom VM.Allocate 403.
- RestoreTestSpec.RestoreTaskTimeout (0→10m default); the restore WaitTask passes
it. Local tier unchanged (10m).
- config RestoreTestPBSRestoreTimeoutSeconds + accessor (default 120m).
- main restoreTaskTimeout(cfg,tier): configured PBS timeout only when tier==pbs,
else 0. Both scheduler + selftest spec builds.
- Tests + WaitOptions red-proof + accessor contract.
The "grant scratch-band VM.Allocate" follow-up is diagnosed not blind-applied:
the scratch is restored INTO /pool/felhom (ACL already grants VM.Allocate), so
the earlier 403 was a consequence of the timeout. No ACL/host-install change.

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`).

Confirmed tenant ACL: DatastoreBackup on /datastore/felhom-offsite/<ns> (NOT

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.
