An event type the hub does not allowlist makes POST /event return 400 and the
event vanishes (R-97a). The controller cannot emit backup_target_absent until
this is live, so the hub half ships first.
E-2 Phase 0 established that an absent backup target has NO prompt signal today.
The controller's drive-gate path stops apps and logs a WARN but emits nothing:
NotifyStorageDisconnected is defined and never called anywhere (verified against
the gitignored-cmd/ trap with a positive control). A drive that is ONLY a backup
target has no apps to stop, so it is entirely silent. The sole signal is the
tier's own failure at its next due cycle -- up to ~24h on the daily local tier,
which is the R-100 shape: a real fault visible only after a deadline elapses.
Added to BOTH registers, because each half fails differently:
allowedEventTypes -- without it the event is lost at the door;
customerMessages -- without it the event IS delivered but in the controller's
raw operator English, and nothing looks broken.
backup_target_absent is deliberately NOT folded into storage_disconnected: that
says "a drive went away and some apps may have stopped"; this says "the thing
that makes your backup survive a disk failure is gone".
Hungarian copy names the consequence, not just the fact. backup_target_restored
is the paired recovery at info severity -- severityNotifies NOT widened.
Three tests pin the pair and the copy's substance. All red-proofed with the
mutation VERIFIED to have landed first: the initial attempt silently no-op'd
(gofmt had realigned the map) and the test "passed" -- a false proof that would
have been reported as evidence.
Green gate: build + vet + test rc=0, run separately from this commit.
v0.78.0 asserted in a comment that a type with no customerMessages entry cannot
reach a customer. It can: templates.go falls back to the raw message when the
entry is missing, and the only customer gate is prefs.EnabledEvents — pure
configuration. A customer with whole_guest_backup_failed enabled would have been
emailed raw English operator text about a backup they cannot act on. The new test
proves it against the v0.78.0 shape.
operatorOnlyEvents is now an explicit register checked before prefs, logging a
skipped/operator_only row so the skip is visible. NOT implemented as 'missing
customerMessages blocks delivery' — several types rely on that fallback on
purpose. The handler comment now names the real mechanism.
internal/quiesce had no route to the hub at all: three failed whole-guest backups
on 2026-07-27 produced zero events. Hub half of the fix.
whole_guest_backup_failed / _recovered are allowlisted with NO customerMessages
entry. Deliberately not backup_failed/backup_completed — those have customer
Hungarian templates AND sit in demo-felhom's live enabled_events, so reusing them
would email the customer that their backup failed while it is still retrying
behind the R-88 breaker.
The recovery joins recoveredPairedDownTypes because it is severity info and
severityNotifies drops info — otherwise the operator hears it break and never
hears it heal. Its customer leg is pairing-gated and can never fire.
Operator cooldown gains a per-tier dimension from the event details, so one tier
cannot mask another for an hour. Narrow: empty suffix unless a tier is sent, so
no existing event type changes.
Let a customer bind their own freshly-installed appliance without the
operator: operator "Send self-bind link" mints a 7-day tokenized
capability link, emailed (Hungarian, sibling sender) to the customer, who
opens a public /bind/<token> page and proves two factors — the console
pairing code shown on the box screen + their retrieval passphrase — and
the hub stages the bind via the same BindAppliance (provenance
customer_selfbind). The box's ~30s appliance poll delivers.
Viktor's three rulings verbatim: console pairing code (no appliance list
ever rendered), operator-sent tokenized link, 5-attempt lockout ->
"call support". Wrong code == wrong passphrase (one generic failure, no
oracle, both factors compared unconditionally); expiry falls back to
operator-bind unchanged.
THE TRAP: one public prefix /bind/, exempt from auth+CSRF at both /login
gate sites via a single isPublicBindPath predicate (tight trailing-slash
match; ServeMux ..-cleans; handler rejects '/' in token). 9 tests
(Scenarios A-F + F1/F2); 4 red-proofs verified red-then-green (lockout,
oracle, widened-prefix, single-active). GC verdict: no appliance GC ->
the 7-day TTL stands alone. Controller/agent untouched; R-27b deferred.
Green: full hub build/vet/test (17 ok) + bash -n + hub confirm gate.

Makes PBS DR storage visible like the restic pool box (v0.64.0), differentiated. Scoping
correction: restic = subaccounts on the shared Hetzner Storage Box (Hetzner API); PBS DR =
the felhom-offsite PBS datastore on the ep0 endpoint VM (NO Hetzner API). Option A
(Viktor-ruled): a read-only `usage` op on the felhom-tenantsync ep0 forced command (twin of
fingerprint), polled by a new hub checker on the 15-min throttle. READ-ONLY throughout.
Phase-0 (gate PASSED): on ep0 (PBS 4.2.3), df -B1 --output=size,used,avail <datastore path>
yields bytes (39990112256/7627939840/... ~19%), read-only, existing sudo context, no admin token.
- scripts/felhom-tenantsync.sh -> v1.2.0: read-only `usage` short-circuit (df on the datastore
path), no customer_id, no admin token, NO mutation. + a bash harness proving zero mutation.
- tenantsync.Client.Usage() + BoxUsage; unknown-op -> typed ErrUsageUnsupported (graceful).
- monitor.PBSDRBoxChecker: OffsiteBoxChecker clone over a usageReader seam; 15-min throttle,
cached PBSBoxSnapshot, escalation-only pbsdr_box_fill on the "pbsdr-box" scope (operator only,
no SaveEvent), recovery re-arm. Fill only. THREE states: ok / unavailable (ep0 <=v1.1.0,
neutral no-alert) / degraded (exec failed, keep last).
- config: Alerting.PBSDRBoxFill{Warn,Crit}Percent (80/90); built with the tenantsync client,
60s sweep, SetPBSDRBox. Hub deploy INDEPENDENT of the ep0 update (graceful degradation).
- web: /offsite splits into Restic + PBS DR hash tabs (endpoint cards under PBS DR); PBS panel;
the single dashboard tile becomes two gauges (RESTIC pct.ratio, PBS DR pct / n/a).
- runbook offsite-endpoint.md 10: v1.2.0 update steps (no sudoers/authorized_keys change).
Tests: 10 Go + the harness; 3 red-proofs (usage mutation, escalation-only, unavailable-drives-band)
confirmed red then restored. go build/vet/test + bash -n + hub confirm gate all pass.
The operator sees the shared pool box's real state on the hub: total box fill vs
capacity, Σ(shared soft quotas) vs capacity (the oversubscription ratio), per-customer
usage/quota bars, and a box-level operator alert (fill % + oversub ratio) on the existing
dispatcher's operator channel. Per-customer fill alerts already existed; the box-level
aggregate was the gap. READ-ONLY against Hetzner (GET only).
Phase-0 probe (gate PASSED): the live pool box 611714 returns capacity via
storage_box_type.size (1 TiB / bx11) and usage via a stats object (size/size_data/
size_snapshots), all bytes; our token reads it (200).
- hetznerapi: additive StorageBoxType + StorageBoxStats on StorageBox (no existing field/
method changed); fake carries them + a GetBoxCalls counter; golden decode test.
- monitor.OffsiteBoxChecker: OffsiteChecker-sibling for the box; fetch-throttled (1 GET/
15min), cached BoxSnapshot, escalation-only + recovery re-arm. FILL (used/capacity 80/90)
+ OVERSUB (Σ shared+enabled quotas / capacity, 2.0x) — independent. Σ from the ConfigJSON
Descriptor (offsite.ReadDescriptor, new), never the report echo; dedicated+disabled
excluded. Scope "pool-box" -> operator channel only, no SaveEvent. Failed fetch keeps the
last snapshot degraded; missing data never becomes 0% and never transitions a band.
- config: Alerting.OffsiteBoxFill{Warn,Crit}Percent + OffsiteOversubWarnRatio (80/90/2.0
defaults; thresholds pending Viktor's ruling). Constructed in the HETZNER_TOKEN branch,
60s sweep, snapshot handed to the web server.
- web: Offsite-tab panel (fill bar, Σ+ratio, per-customer usage/quota rows) + a compact
dashboard tile; reads the cached snapshot only, never fetches; nil -> "not configured".
Tests: 10 new + 4 red-proofs (throttle, Σ filter, escalation-only, failed-fetch honesty),
all confirmed red then restored. go build/vet/test all pass; hub confirm gate OK.
ProcessEvent routed only warning/error; a critical-severity event was silently dropped.
Now routes warning/error/critical, logs unrecognized severities, and guards a nil
GetNotificationPrefs (which would panic/crash the hub). host_disk_critical emits its
natural critical severity.

New HostDiskChecker on the 60s sweep alerts the operator when a Proxmox host root
filesystem crosses warn (90%) / crit (95%). Born/persistent (a disk already full at
hub restart alerts on cycle 1); distinct host_disk_* event types from the guest disk_*;
critical band maps to severity error (the dispatcher only routes warning/error).

Restores notify/templates.go, store/telemetry.go, web/configs.go to upstream —
those were alignment-only churn from a tree-wide gofmt, not part of slice 3. Keeps
the host-domain diff additions-only.
