hub v0.66.0 + ISO v1.20.0: customer self-bind (R-27 slice 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.

Viktor's 3 rulings verbatim (console code not a list; operator-sent link; 5-attempt lockout→call support). No oracle; expiry falls back to operator-bind; THE TRAP `/bind/` exemption tight (single predicate, 4 red-proofs). GC verdict §3 (no appliance GC → the 7-day TTL stands alone). **Live first-run + new-ISO console banner fold into the supervised rehearsal (R-1).** Reused the appliance_registrations + one-shot delivery machinery; the capability link is the whole customer-auth surface (no login system built). Controller/agent untouched. See hub v0.66.0 REPORT. **Multi-box per link is out of scope by design** (single-active, one-shot → binding several boxes = repeated operator sends) |
+| R-27b | **Customer self-bind, second-box flow (controller side).** For a customer who ALREADY has a bound box and installs another, the controller shows a dismissable "bind another box" prompt (and a bind-later entry under settings) that walks to the hub `/bind/` page — so a returning customer isn't emailed a fresh operator-sent link for every box. Mechanism sketched in the hub v0.66.0 REPORT; NOT built (R-27 slice 1 deliberately did not touch the controller). | M | idea (minted by hub v0.66.0) | Origin: hub v0.66.0 slice-1 ship (first-box only). Reuses the same `/bind/` public page + tokenized-link machinery; adds a controller-side entry point + the operator "mint a link for an existing customer" affordance |
 | R-25b | **Customer DELETE ↔ RESET consistency.** The middle-tier Customer RESET (hub v0.61.0) runs the full external teardown (Hetzner sub-account/box + PBS namespace/groups/token) and refuses while any host row exists. The Danger-zone DELETE still (a) leaves host rows and (b) does NOT run that teardown — it purges escrow custody + drops the config only. Decide the model: DELETE requires a prior RESET, or DELETE subsumes RESET's teardown, or they stay orthogonal (RESET = recycle-in-place, DELETE = escrow-purge). | S | idea | Origin: hub v0.61.0 RESET ship. Flips a future "customer fully offboarded (external resources released)" map row. Cheap once the model is chosen |
 | R-25 | **Device-node TOCTOU hardening (drive init).** Graduate the controller v0.141.0 Observation: the `format → resolveEnrollUUID(path) → AssignDisk(uuid)` sequence has a narrow /dev-re-enumeration window (agent-guarded on the destructive format via anti-retarget durable-id; benign fs-UUID mount). Bind resolve+assign to the format's durable-id so the mount can't target a moved node. | S | idea | From the v0.141.0 F6 commit's security-review finding (`felhom-controller` REPORT). Low real risk (single-operator, agent-guarded), but cheap to close |
 | R-24 | **Guest RAM resize (live) — SHIPPED (agent v0.90.0 + controller v0.143.0, 2026-07-17).** The customer right-sizes the guest's memory from the controller's Rendszer page; the agent enforces every bound fresh + applies via PVE `SetConfig` (live cgroup, no reboot, Phase-0 proven). **Framing note:** the original hub-desired-state framing is SUPERSEDED by Viktor's controller-direct ruling (2026-07-17) — the resize is controller→agent local-API, never through the hub. Memory only (cores stay observation). Deployed + live-validated on the demo (refusals render Hungarian end-to-end); a successful grow on a normal-sized box folds into the rehearsal. **Cores/live-resize as hub desired-state is NOT built** (deferred, low demand). | M | **SHIPPED** | See felhom-agent + felhom-controller REPORTs; capability-map row "customer right-sizes guest RAM". |
