Seam sweep: TieredBackend was the FIRST, not the only one. BackupArchiveLister
has the identical silent-degrade shape and a worse blast radius (it degrades to
the pre-R-84 in-memory-only behaviour), and no compile-time witness existed in
production code anywhere in either repo. No defect found, so no version bump and
no deploy — the witnesses are guards, proven by breaking a signature and watching
go build fail where it previously passed.
Live outage: age_state=unknown captured on real hardware for the first time, with
demo-felhom's local tier genuinely due throughout — the controller deferred and
zero app stacks were stopped. The R-88 breaker did NOT arm and no
whole_guest_backup_failed travelled, because felhom-pbs was not due; recorded as
conditions-did-not-arise rather than claimed as coverage.
Post-boot: the volume changed device name (sdb->sda) across the reboot and the
mount survived only because fstab uses by-id. That was never tested before.
Corrects two wrong severity readings with evidence from the box and the code.
The PBS outage was ~15 min (07:00-07:18 UTC), caused by a global OOM at 06:58:12:
proxmox-backup-proxy peaked at 3.2G on a 3.8G box and a concurrent 1.9G rsync
tipped it over. Root SSH to that box works from DooPlex via the public IP, not
from felhom-pve via the tunnel IP — the documented path I failed to try first.
R-88: internal/quiesce has NO failure limiter, backoff or breaker; the loop
stopped after three cycles only because PBS recovered. Verified additionally that
scheduledRunAllowed (quiesce.go:476-478) returns true whenever lastAgeSecs is nil,
so the same missing value that makes every poll due also bypasses the time-of-day
gate — the cycles ran outside the [04:30,08:30) window. Fixing the due-verdict
without fixing the nil-age bypass would leave the hole open.
Recorded after the session report was written. The offsite PBS service stopped
listening on 8007 five minutes after this session's 14.46 GB restore-test read
from it; the box is up and the tunnel is healthy, but no SSH key to it exists so
the cause is unestablished — the restore load is a plausible mechanism on a cx23
and is recorded as correlation, not cause.
The agent restart then exposed R-88: an unreachable target reads as 'no backup
exists', so the offsite tier is perpetually due and the controller runs a full
quiesce cycle every ~5 min. Operator ruling: leave it running, it self-heals when
PBS returns and masking it would hide the fault.
The unattended offsite restore-test on demo-felhom passed: 14.46 GB archive,
duration_s=635.07 (10m35s), then it rotated to the local tier. Persisted state
confirms the credit: {"felhom-pbs": "2026-07-27T06:14:42Z"}.
CORRECTION: I estimated ~2 hours for this restore. It took 10m35s. I derived
the estimate from a download rate measured during the FAILED attempt, which was
running under contention; the real link does ~1.4 GB/min. I then used that wrong
figure to raise a design concern — that the heavy-op gate would block backups
for hours on this box — which at 10 minutes largely evaporates. An estimate
extrapolated from a degraded measurement is not a measurement.
The SPEC's closing risk note is corrected in place, with the original left
visible for the lesson.
R-86 (NEXT, operator ruling 2026-07-27): backup-ALIGNED restore-test scheduling
— test a tier ~1 day after ITS OWN backup. R-85 schedules on a free-running
interval, which cannot express 'the day after the PBS backup': any fixed offset
drifts, so alignment would be luck. Shape: trigger from the tier's own last
successful backup rather than a clock. Interim in force: 302400s (3.5d), which
lands each tier ~weekly — the cadence half of the ruling, not the alignment half.
R-87: the restic app-data offsite tier is NEVER restore-tested. R-85 covers
whole-guest vzdump tiers only; the agent has no restic surface. That is arguably
the tier that matters most — the only one that survives losing the box AND
carries the customer's app data, since the whole-guest snapshot excludes the
bind-mounted drives. Exactly the state PBS was in before R-85.
REPORT.md: the full R-80 -> R-85 arc, including a section on the seven mistakes
I made and the two recurring shapes behind them (inferring behaviour from an
artifact instead of the code that consumes it; reading a result without its exit
code). Records demo-felhom's restore-test as IN FLIGHT at close, with the manual
recovery step if the deferred restart watcher does not complete.
Hub gate green (17 packages, rc=0).
Restore round-trip on demo-hp: pass=true, verified=boot+running,
mount_parity=ok, source_tier=pbs (the v0.100.0 fix — the earlier attempt said
'local' and died at 600s), 4m5s restore+boot+verify+teardown, clean teardown
with no 403 and no leak. That last point confirms 06's reading that the
teardown 403 was a phantom, and corrects my earlier framing of it as a standing
privilege gap.
Multi-tier quiesce driven through the REAL UI endpoint (authed+CSRF):
exactly ONE stop/start pair with BOTH backups inside it, local-first/PBS-last,
app quiesced through the non-last tier, early resume on the last tier's
snapshot. Total downtime 1m27s for both tiers; app healthy after.
Capability map row upgraded IMPLEMENTED -> PROVEN-LIVE, kept distinct from the
DR-tier row above which proves ACTIVATION not ARRIVAL. Remaining gaps recorded:
the SCHEDULED restore-test still only selects the primary tier (manual path
proven, unattended not), and the hub infers cadence from storage type.
Slice D.1 — host-install 1.20.0: a FRESH box defaults to local-daily +
offsite-weekly (felhom-pbs, 604800s, keep_last=2). setdefault semantics proven
both ways: fresh gets the tier, an UPGRADE preserves the existing backup block
verbatim — so an in-place upgrade can never silently start writing to an
offsite datastore. Existing boxes are migrated explicitly.
Slice E:
- 07-backup-architecture.md: honest status header per CONTEXT ruling S-2, with
an explicit STALE-outside-the-PBS-tier verdict (the controller tiers were last
verified 41 controller versions ago). The PBS row claimed 'PBS on DooPlex'
(the retired spike store) with no cadence; it now names felhom-pbs ->
felhom-offsite on ep0 over wg-felhom, weekly, keep_last=2. NOT marked
ratified — that is Viktor's review of the section 10 list. Discharges R-83.
- 06-offsite-connectivity.md: the target-split remaining-work note collapsed
(shipped), and records HOW S4.1's tier-aware timeout silently regressed — the
mechanism was never removed, its INPUT changed when local_backup_target was
retargeted to 'local'. Also notes S4.1 already diagnosed the teardown 403 as a
phantom (a timeout consequence, not an ACL gap).
- capability map: new row for recurring offsite backups actually LANDING, as
distinct from the existing row proving ACTIVATION. IMPLEMENTED, not
PROVEN-LIVE — the restore round-trip has not completed under the fixed code.
- ROADMAP: R-82 SHIPPED with its remaining gate named, R-83 DISCHARGED, R-84
left open.
- CONTEXT + REPORT: the arc, including the mid-arc correction I had to make.
- B2 demo-hp + B3 demo-felhom migrated to the island (agent 0.96.0), apps
served throughout (0 container restarts), island /storage 200, LAN DNS pinned
to the LAN IP, hub reports 0.96.0. No rollback.
- capability-map 'site/network change' row PARTIAL -> PROVEN-LIVE
- ROADMAP R-50 -> SHIPPED (fleet-migrated); add R-74 (island on Peti's cluster)
- nodes.md: both boxes island-bound, agent 0.96.0
- A4: scratch guest provisioned from golden on the island-configured drill came
up with net1 automatically (zero manual edits) — the v0.96.0 provisioning path
proven live. Spike method caveat CLOSED.
- REPORT: Phase A done + vouched 0.96.0; B0/B1/A4 done; B2/B3 await operator go.
Provisioned nested-PVE drill 'drill-r50' (qm300 on demo-hp) via the v1.25.0
nested-vm ISO through the real day-0, then ran the R-50 empirical spike:
- vmbr9 portless island bridge + guest island NIC hot-add (LAN undisturbed)
- F1 replay money shot: LAN move survives on the island; LAN-literal bind
reproduces the 2026-07-20 daemon-exit bug verbatim
- dnsmasq trap confirmed live + lan_resolver.host_ip fix proven
- pin address-independent (leaf SHA-256 unchanged, HTTP 200 over island)
- survival matrix: agent/guest/host-cold-reboot all return on the island
Docs: SPIKE verdict BLOCKED->GO, ROADMAP R-50 SPIKED->GO, nodes.md drill VM,
REPORT overwrite.
Virgin-ISO nested drill closed the train: dead-NIC install baked the
fallback (incl. the dead default gateway), the R-59 screen painted
(capture committed beside the spike doc), the cable move healed +
registered at the hub in 23s unaided, and the build's rootpw file
matched the installed box's shadow hash. R-59 SHIPPED with the recorded
deviation (first-boot gate; installer-initrd abort out of scope by
operator ack). R-60 SHIPPED (spike + drill cited; F-P9 route-flush fix
included). R-61 slice 1 SHIPPED. New R-62 row (hub delete-dialog
cosmetics, XS). Capability map: new PROVEN-LIVE row (nested != metal,
said so). Cleanup verified: felhom-pve interfaces byte-identical,
bridge/VMs/ISO removed.

Found validating v0.69.0 against the live hub. demo-vm-felhom was deleted
on 07-18 and was still on the Customers list AND still raising offsite_stale
(10 events, latest 07-21 17:34, operator email at 19:34) — because
GetCustomers() is report-derived and no lifecycle tier ever deleted a report.
New leg 3 (residue), before the record purge: reports, app_telemetry,
app_log_tails, log_tail_requests, customer_notifications, plus the
credential-bearing appliance_registrations and selfbind_tokens. Audit
(events, notification_log) and F-14 provenance still survive.
Ghost customers are now deletable: 404 means "nothing here", not "no config
row". With no config row the offsite descriptor is unknowable, so the Hetzner
and descriptor legs record skipped_no_config rather than a bare "skipped".
Two more red-proofs.

POST /configs/{id}/delete now runs hosts -> RESET -> purge behind three
acknowledgements, a typed customer-id, a stale-preview check and the
ONLINE-host refusal (every gate before any write, so a refusal has zero
side effects). The shallow handleConfigDelete is gone.
Two invariants are asserted, not just commented: ruling 3 is preserved by
construction (leg 2 never sees a host row) and retained escrow custody is
purged exactly once, in leg 3 (leg 2 runs with purgeEscrow=false).
handleCustomerReset's committed half was extracted as commitCustomerReset;
the standalone RESET path is byte-identical to v0.68.1 and its suite is
untouched. Five red-proofs run.

Dead primary: degraded in 13 s, exactly one app_start_failed, banner rendered and
self-cleared. Boot orphan: recovered in one attempt with zero alerts. Dead dhclient:
detected in 57 s on process liveness while the lease was still live, healed 120 s after the
kill — the tunnel never dropped, so the outage was prevented rather than observed.
P1 answered as a by-product: bookstack StartedAt == the moment bootrecon StartStack
returned, so unless-stopped did NOT resurrect it. F5 hypothesis confirmed.
New R-55, surfaced by the leg designed to prove the opposite: the boot bind gate recreates
and STARTS every deployed drive-backed app unconditionally, so a customer Stop does not
survive a reboot for those apps. Predates R-52 and does not implicate it, but it narrows
R-52's practical scope and needs a ruling.
R-51's roadmap diagnosis is corrected at the source: aggregation returned StateRunning
("partial") for a running/stopped mix, so the stack read RUNNING and IsDownState was never
consulted about at all — the constraint that row protects was never in tension
with the fix.
New R-54 row closes the INCIDENT-guest-dhclient-killed-2026-07-20 §5 OPEN RISK, and records
the design fact that makes it work: liveness of the DHCP client is itself a probe, because
the damage is timed and the address outlives its cause by 1-2 hours. The static-guest leg is
deliberately deferred to R-50.
New capability-map row is IMPLEMENTED, not PROVEN-LIVE: one leg is live (the watchdog's
healthy cycle on felhom-pve), the three that matter are destructive and operator-present and
have not run.
PROMPT-TEMPLATE §10 gains the seam-discipline row, including that a strings.Contains source
assertion is NOT sufficient — a commented-out call still contains the string.
felhom-pve joins the tailnet as a host package (100.70.170.35, expiry
disabled); DooPlex already advertised 192.168.0.0/24 via its GitOps k3s
tailscale pod (100.107.87.53). ssh felhom-pve now targets the tailnet IP
(direct-over-LAN at home, tunnel when away); felhom-pve-lan = LAN fallback.
--accept-dns=false on the host. Host converted static->DHCP (reservation
keeps .162 at home). Measured: --accept-routes hairpins the local subnet
at home -> travel-only opt-in. PBS is offsite (own WireGuard tunnel), needs
none of this. Recorded not fixed: controller<->agent plane hard-pinned to
192.168.0.162 (agent listen_addr + guest bootstrap.json) -> not yet portable
off-LAN. No code changed. Full doc: documentation/operations/tailscale.md

Golden 0.146.0 baked on the drill VM and published to gitea:
felhom-golden/0.146.0/golden.tar.zst
sha256 4834c703162c5437467a329144b1a523019bf5693ab9d439558be7323587e955
612696588 B (584 MB archive), controller 0.146.0 confirmed baked in
All pass markers green: Result=success/ExecMainStatus=0, 0 FATAL/exclusions,
docker OK (overlay2), ALL THREE mounts included (rootfs + mp0 /var/lib/docker +
mp1 /mnt/sys_drive), pre-delete HTTP 404 (the pre-gate — version did not exist),
upload HTTP 201.
Integrity verified independently of the build host: anonymous GET | sha256sum
matches byte-for-byte, ranged GET 206, content-length matches the bake's bytes.
The version now appears in the hub dropdown (0.136.0, 0.143.0, 0.146.0).
Teardown per GL-1: log copied out as evidence first
(180:/mnt/5_hdd/felhom.eu/drill/bake-0.146.0.log), guest 9100 purged, token +
script + log shredded in-VM, VM off, qemu confirmed gone via `ps -eo comm` (not
the self-matching pgrep -f), drill disk reverted to the virgin snapshot exactly
as found. Token-leak grep = 0 against the LITERAL token value, on the bake log
and both ISO build logs from this session.
REMAINING is operator-only and password-gated: Day-0 manifest Golden -> 0.146.0
(Agent stays 0.90.0, MinAgent stays 0.90.0 — v0.146.0 declares no new agent
coupling), then the floor -> v0.146.0 saved LAST.

ROADMAP:
- R-39 gains the full live diagnosis and REFUTES the brief's hypothesis. The
generation IS bumped (SetHostDesired bumps unconditionally, 2->3) and
applyPBSDR is exonerated, so no hub fix was shipped. The real mechanism is a
signal mismatch: the hub's re-consume signal is a generation bump + poke,
while the agent re-applies on a change of the DESCRIPTOR CONTENT HASH
(manager.go ~L235). An ep0 re-issue re-keys the secret of an EXISTING token,
so token_id/fingerprint are unchanged, the descriptor is byte-identical, the
hash never moves, and the fresh secret is never consumed -> 401 forever.
Proof: consumed-failed.json carries the same hash a4e5424... as the marker
written two minutes before the re-issue.
Records the second defect found while healing (wrapper reconcile passing
--server, fixed in agent v0.90.1), marks the box HEALED with evidence
(pvesm active, token 200, a real 9.7 GB encrypted backup listed PBS-side),
and leaves the fleet fix explicitly pending its own spec.
- R-33 collapses to SHIPPED (scripts v1.21.0), incl. why
TimeoutStartSec=infinity is the load-bearing half.
- Pre-invite checklist: golden target moves 0.145.x -> 0.146.0 and notes it is
now MORE stale, since v0.146.0 is live on the demo box while the golden still
bakes 0.143.0.
REPORT overwritten with the train: R-39 diagnosis verbatim + heal evidence, the
two ISO shas with the byte-identical-payload verification, the nav polish and
why the screenshot leg could not be done (the demo controller password is
customer-owned since the claim flow, so the build-server credentials are stale),
Phase 4 skipped cleanly, and Phase 5 deferred rather than half-run.
