Live through the real ingress: public /bind/ renders logged-out with the
no-oracle expired state (200-not-500 proves selfbind_tokens migrated);
gate intact (/ and /hosts -> /login); CSRF exemption is /bind/-only
(POST /bind/ no-CSRF 200 vs POST /customers/x/block no-CSRF 302).
Operator-minted full walk + new-ISO console banner remain operator/R-1.

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.
The immediate-sync arc covered only operator-initiated desired-state changes;
system-initiated mutations bumped the generation silently, so a freshly onboarded
box waited a full agent tick for state the hub had already minted (observed live at
slice-C onboarding). Wire the existing, live-proven notifiers into every system site
on the correct plane — call-site wiring only, no new mechanism.
Agent plane (poke.Notifier):
- web/pbsdr.go: PBSDRAutoProvision (the observed lag), ReissuePBSDR (also lifts the
pbsdrheal reconciler escalation, zero reconciler changes), handlePBSDRReissue —
each pokes AFTER the successful SetHostDesired, never on a blocked/error path.
- api: new nil-safe Poker seam (PokeHost/PokeAllHosts + SetPoker); handleAdminSetDesiredState
pokes the target host; handleAdminSetOperatorPeer fires PokeAllHosts only when the
fleet generation bump succeeded (fire-after-commit).
- main.go: one poke.Notifier now feeds both planes (SetPoke + SetPoker).
Controller plane (intent.Hub.Bump):
- api/reissueOnReenroll: one nil-guarded bump so a long-polling controller wakes in
seconds instead of on the 15-min cycle.
Deliberate non-sites (unchanged): WG register (undeliverable pre-tunnel — the agent
fast-tick SECONDARY owns it), WG delete (transport removed), pbsdrheal Restage (no
generation bump → the 60s ticker is the pickup path). internal/pbsdrheal byte-unchanged.
Tests: 10 non-hollow tests (web async channel-synchronized fake sender; api synchronous
fake Poker) with explicit zero-count negatives; representative red-proofs per group
(A/B/C/D) run-fail-restored. Green: go build/vet/test all pass.
A generic ISO carries NO customer secret. The box registers itself at the hub
as an unclaimed appliance; the operator binds it to a customer; the hub delivers
the customer-id + retrieval passphrase ONCE; day-0 completes via the slice-A path.
Hub (v0.62.0):
- store/appliance.go: appliance_registrations keyed by (uuid, mac_set) — MAC set
is the tiebreaker (duplicate SMBIOS UUIDs); token stored as sha256 only.
Idempotent register (sticky-discard), atomic one-shot delivery, bind/discard.
- api/appliance.go: POST /appliance/register (the one unauth endpoint, per-IP
rate-limited, 256-bit token); GET /appliance/poll (404 no-oracle / 204 unbound
/ 200 deliver-once / 410 delivered). Passphrase read live, never logged.
- web/appliances.go: Hosts-page "Unclaimed appliances" section + BIND (customer
picker, host count display-only) + DISCARD; SSH host-key fingerprints; events.
- Red-proofs: one-shot delivery + register idempotency (both proven red);
404-no-oracle, sticky-discard, bind staging, render. Green + confirm gate.
Scripts (v1.19.0):
- felhom-bootstrap.sh: ONE unit, TWO modes. Direct (env has customer/passphrase)
= slice-A path, byte-identical, only branched around. Pairing (generic) =
register + poll (RestartSec=30 is the poll timer); on delivery write the env
0600 and fall through to direct. Secrets + token shredded on success.
- build-felhom-iso.sh --pairing: generic secret-free ISO, -generic filename,
manifest mode=pairing. profiles/generic.profile (new).
- test/bootstrap-modes.sh: Scenario D (direct = zero appliance calls) + pairing
register/poll + delivery handoff — all green in a debian container.
Closes N100 F1 (HIGH): cheap AMI (AN3PLUS 0.01-class) UEFI firmware can't
relocate the ISO's stock signed GRUB from USB (relocation 0x0). The run's live
grub-mkimage workaround is now a first-class pipeline mode.
- build-felhom-iso.sh: --loader shim|mkimage (default shim, byte-for-byte
unchanged; profile-settable FELHOM_LOADER; --loader wins). Loud banner +
manifest loader:/grub-mkimage: fields + -mkimage filename suffix.
- mkimage-surgery.sh (new): post-prepare-iso, in the assistant container. Builds
a monolithic grub-mkimage loader from the ISO's own GRUB (module set from its
grub.cfg; embedded search --fs-uuid -> configfile the real menu). Swaps it into
the ISO9660 tree (real lowercase path) + the efi.img ESP; xorriso re-master
preserves BIOS-hybrid + UEFI + GPT-ESP, drops only Apple HFS+/APM. Recipe from
the N100 run evidence, not re-derived.
- Dockerfile.assistant: grub-common + grub-efi-amd64-bin + mtools + dosfstools.
profiles/n100.profile (new, mkimage + SB-off note).
- Validated on nested VM 311 (RUNBOOK-B legs): leg1 shim boots+installs under
OVMF SB-enforcing + SeaBIOS; leg2 mkimage boots+installs under SB-off; leg3
(red-proof) mkimage under SB-enforcing FAILS Access Denied (unsigned -> SB must
be OFF); leg4 surgery byte-identical payload. bash -n + shellcheck clean.
Physical N100 closure folds into the rehearsal (n100-safety match-nothing ISO
built + sha-recorded, unbooted). PXE stays a deferred R-21 note.
- DeleteHost(deleteEscrow) demotes current host_escrow into host_escrow_superseded (copy-before-delete, same tx), spares existing; one shared demoteCurrentEscrowTx (reused by SaveHostEscrow). F-14 provenance/gate unchanged.
- DeleteCustomerConfig now purges both escrow tables for all the customer's hosts incl. already-deleted (F-14 provenance UNION) — the one true purge point.
- Wording: checkbox/refusal/Danger-zone → demotion. S6b OBSOLETE. Red-proofs TestDeleteHost_Demotes + TestDeleteCustomer_Purges + wording guard.
GET /api/v1/wait long-poll: the box holds an authed hanging GET; the hub
completes it the instant any operator intent bumps that customer's in-memory
generation, then the box fires its ordinary report and the ACK delivers
everything through the unchanged machinery. 240s hold with a 25s heartbeat
newline defeats the nginx 60s proxy_read_timeout with no ingress annotation;
WriteTimeout lifted per-connection via ResponseController.
- internal/intent: per-customer generation counter + waiter registry
(Bump/Wait/Close), coalescing to latest, race-closer, in-memory by design.
Red-proofs: counter-vs-queue + race-closer (run-fail-reverted).
- api/wait.go: the endpoint (per-customer only; global key 400; A cannot see B).
- web bumps after every intent write (fire-after-commit): config CRUD, claim
resend, offsite re-issue/freeze, password regen, block/unblock, floors
(global bumps all config-managed), controller log-tail + log-bundle.
- main.go: one intent hub shared by web+api; Close() before server.Shutdown.
Pairs with controller v0.140.0 (the long-poll client). Grounding:
documentation/audits/SPIKE-immediate-sync-transport-2026-07-16.md.
Empirical spike (demo arc, docs-only, no product code). Measures the two hub->box
'sync now' transports. Verdict: (b) long-poll = primary for user config (hub-only,
reaches controller, no ep0/WG/agent coupling; binding ceiling = twin 60s nginx
proxy_read_timeout + hub WriteTimeout, both config lifts); (a) ep0-relayed poke
= agent-plane nudge (~0.42s, zero ep0/box infra change, EKEYREJECTED-confined).
