+- **2026-07-17 — OFFSITE POOL-BOX AGGREGATE shipped (hub v0.64.0, R-5).** The operator now sees the
+  shared pool box's real state on the hub: total fill vs capacity, Σ(shared soft quotas)/capacity (the
+  oversubscription ratio), per-customer usage/quota bars, and a box-level operator alert (fill 80/90%,
+  oversub 2.0×). New `monitor.OffsiteBoxChecker` (OffsiteChecker-sibling): fetch-throttled to one Hetzner
+  GET / 15 min, cached `BoxSnapshot`, escalation-only + recovery re-arm; two INDEPENDENT signals (fill +
+  oversub). Capacity = `storage_box_type.size`, usage = `stats.size` (Phase-0-pinned, bytes); Σ(quota)
+  from the ConfigJSON `Descriptor` (`offsite.ReadDescriptor`, new — NEVER the report echo; dedicated +
+  disabled excluded); per-customer USAGE from the report echo. Events scope `"pool-box"` → operator channel
+  only, no SaveEvent. Web: Offsite-tab panel + compact dashboard tile, reading the cached snapshot only
+  (never fetches). **PROVEN-LIVE (data pipeline):** the in-cluster checker computed the real box —
+  `0.2% full (2.6 GB of 1.00 TB), Σ shared quota 150 GB, oversub 0.15x`. **DECISION: thresholds
+  (80/90/2.0×) are Claude's encoding — Viktor's ruling pending; named `Alerting.OffsiteBox*` keys = the
+  one-line flip.** **OPEN:** the UI render is unit-verified only (hub UI password-gated → CC can't
+  screenshot); the alert emails are unit + red-proof verified but NOT fired live (real pool nominal — a
+  live-fire would email Viktor; offered on demand). READ-ONLY against Hetzner throughout. See REPORT.md.

 - **2026-07-17 — SYSTEM-INITIATED IMMEDIACY wired per-plane (hub v0.63.0).** The immediate-sync arc
   covered only OPERATOR-initiated changes; **system-initiated** desired-state mutations bumped the

-**New tests (10), all green:**
+10 new tests, all green:
 
 | Test | Group | Asserts |
 |------|-------|---------|
-| `TestPBSDR_AutoProvisionPokes` | A | auto-provision success → exactly one poke to the resolved WG /32 (10.77.0.2) within 2 s |
-| `TestPBSDR_AutoProvisionBlockedDoesNotPoke` | A (neg) | blocked precondition (no WG peer) → zero pokes |
-| `TestPBSDR_ReissueCorePokes` | B1 | `ReissuePBSDR` success → one poke to the host's /32 |
-| `TestPBSDR_ReissueCoreErrorDoesNotPoke` | B (neg) | tenantsync-error reissue → zero pokes (fire-after-commit) |
-| `TestPBSDR_HandleReissuePokes` | B2 | operator button success → one poke |
-| `TestAdminSetDesiredState_PokesTargetHostOnly` | C1 | admin-set success → PokeHost==1 (target only), PokeAllHosts==0; invalid-JSON path → 0 |
-| `TestAdminSetDesiredState_NilPokerNoPanic` | C1 (nil) | nil poker → mutation still 200, no panic |
-| `TestAdminSetOperatorPeer_PokesFleet` | C2 | operator-peer success → PokeAllHosts==1, PokeHost==0 |
-| `TestReenroll_BumpsIntent` | D | re-enroll → intent generation advances (synchronous) |
-| `TestReenroll_NilIntentHubNoPanic` | D (nil) | nil intent hub → enroll still 201, no panic |
+| `TestOffsiteBox_FetchThrottle` | A | ≈4 API reads over an hour of 60 s sweeps (not ≈60); snapshot populated |
+| `TestOffsiteBox_OversubMath` | B | Σ = shared+enabled only (A 500 + B 700); dedicated/disabled excluded; ratio = Σ/capacity = 1.17× |
+| `TestOffsiteBox_FillBands` | C1–C5 | 75%→no emit; 82%→1 warn; 85% in-band→no re-emit; 92%→critical; 70%→re-arm; re-breach→emit; every emit scope "pool-box" |
+| `TestOffsiteBox_OversubIndependent` | C6 | 2.3× oversub fires alone with fill nominal (50%) — distinct event, no fill emit |
+| `TestOffsiteBox_FailedFetchHonesty` | D | failed fetch keeps last values, marks Degraded, no band transition, no emit |
+| `TestOffsiteBox_ZeroCapacityGuard` | — | zero capacity → degraded snapshot, no division, no alert |
+| `TestStorageBox_DecodesProbeShape` | 1.1 | golden probe JSON decodes to the extended type; data+snapshots == total |
+| `TestProcessEvent_PoolBoxScopeOperatorOnly` | C7 | a "pool-box" event reaches the operator ONLY (no customer email) |
+| `TestOffsiteBoxPanel_NotConfigured` | E | nil provider → "not configured", no fake zeros |
+| `TestOffsiteBoxPanel_WithData` | E | panel renders capacity/ratio + per-customer rows + "no usage reported yet" |
 
-Async web assertions synchronize on a buffered channel in the fake sender with a bounded `select`
-(≤2 s), never sleep-poll. The web fake sender structurally satisfies poke's unexported `pokeSender`
-seam (value passed, type never named); the notifier is a REAL `poke.Notifier` over the test store —
-exactly as `main.go` builds it. The api fake `Poker` satisfies the exported `api.Poker` interface and
-counts calls synchronously.
+**Red-proofs (run-fail-restore), all confirmed red then restored:**
 
-**Red-proofs (run-fail-restore), one representative per scenario group:**
+| # | Removed | Test | Result |
+|---|---------|------|--------|

+| ii | the shared+enabled Σ filter | `OversubMath` | FAILED ("Σquota = 11499… want 1200") → restored |
+| iii | the escalation-only guard | `FillBands` | FAILED ("C3 same-band must NOT re-emit, got 2") → restored |
+| iv | keep-last-on-failure (zero the snapshot) | `FailedFetchHonesty` | FAILED ("must not alter… before …, after 0/0") → restored |
 
-| Group | Removed | Test | Result |
-|-------|---------|------|--------|
-| A | `PBSDRAutoProvision` poke (Part 1.1) | `TestPBSDR_AutoProvisionPokes` | FAILED red ("no poke within 2s… 10.77.0.2") → restored |
-| B | `ReissuePBSDR` poke (Part 1.2) | `TestPBSDR_ReissueCorePokes` | FAILED red ("no poke within 2s… 10.77.0.2") → restored |
-| C | `handleAdminSetDesiredState` poke (Part 2.2) | `TestAdminSetDesiredState_PokesTargetHostOnly` | FAILED red ("PokeHost targets = [], want [h1]") → restored |
-| D | `reissueOnReenroll` bump (Part 3) | `TestReenroll_BumpsIntent` | FAILED red ("intent generation = 0, want > 0") → restored |
+Full suite: `go build ./... && go vet ./... && go test ./...` — all 17 packages green; hub confirm gate OK.
+Test count: +10 (monitor +6, notify +1, hetznerapi +1, web +2).
 
-These tests fail on the pre-fix tree by construction; a representative removal per group was
-demonstrated (B2 and C2 share their group's wiring shape with the demonstrated B1/C1 removals).

+Built + pushed `felhom-hub:0.64.0` on 180 (build source at `4bb2df0`/`a4268c3`). Manifest bump (`66da0c4`)
+→ ArgoCD hard-refresh (rev `66da0c44`, OutOfSync) → deliberate sync → rollout succeeded; image
+`felhom-hub:0.64.0`. Startup log:
 
 ```

-deployment "hub" successfully rolled out
-image: gitea.dooplex.hu/admin/felhom-hub:0.63.0

-# startup log (poke ENABLED — POKE_SSH_KEY_FILE Secret present in this environment):
-[INFO] felhom-hub 0.63.0 starting
-[INFO] agent-plane poke enabled (endpoint 167.233.158.164:22, user felhom-peersync; web + api admin seams armed)

+[INFO] Offsite pool-box checker initialized: box=611714 fill warn=80% crit=90%, oversub warn=2.00x, refresh 15m0s
 ```
 
-The startup line is the new one — "web + api admin seams armed" confirms `apiHandler.SetPoker(n)` was
-wired alongside `webServer.SetPoke(n)` over the one notifier. Poke is enabled (not the disabled
-fallback), so all wired sites are armed live.
+### 6. Live-rendered values (the PROVEN-LIVE evidence)
 
-### 7. NOT yet live-validated (real system-initiated events only)
+The hub UI is operator-password-gated (CC cannot log in — hub CLAUDE.md), so the panel/tile can't be
+screenshotted directly. Instead the in-cluster checker's first refresh proves the **full pipeline against
+the REAL pool box** — the exact numbers the panel/tile render:
 
-The new pokes/bumps fire only on real system events, none manufacturable non-destructively from this
-task. Acceptance bar here = **unit tests + deploy + startup-log verification**. Unfired live legs, to be
-observed at the rehearsal's bind sequence (`RUNBOOK-rehearsal-v3 S5`):
+```
+[INFO] Offsite pool-box refreshed: 0.2% full (2.6 GB of 1.00 TB), Σ shared quota 150 GB, oversub 0.15x
+```
 
-- **Auto-provision poke** — fires when a DR-ON customer's host registers its WG peer for the first time
-  and the atom provisions (the exact observed slice-C lag).
-- **Reconciler-escalation poke** — fires when the pbsdrheal reconciler escalates to `ReissuePBSDR` (a box
-  stuck in `waiting_secret`/`consumed_failed` after losing its converged marker).
-- **Clean-slate re-enroll bump** — fires when a wiped, re-minted box re-enrolls for a claimed/offsite
-  customer (on that path the controller usually does not exist yet; its startup fetch covers that shape).
-- **Operator-button / admin-api pokes** (`handlePBSDRReissue`, admin desired-state / operator-peer) — the
-  operator-triggered legs; exercisable in a supervised session but not fired here.
+Live-confirmed end-to-end: capacity **1.00 TB**, used **2.6 GB** (matches the Phase-0 probe's 2746220544 B),
+fill **0.2%**, Σ shared quota **150 GB** (one live shared customer), oversub **0.15×**. The panel-render is
+UNIT-verified (`TestOffsiteBoxPanel_*` render the real snapshot shape); the data feeding it is now proven
+live.
 
-The **first-hold-baseline race** stays OPEN by design: a bump landing during a fresh controller's FIRST
-wait is recorded as baseline without firing (the ruled fix is carrying `intent_gen` in the report ACK —
-its own future task, out of scope).
+### 7. NOT yet live-validated
 
-### 8. Part-4 audit table — EVERY desired-state mutation site
+- **The panel/tile UI render** could not be screenshotted (hub UI password-gated). It is unit-verified via
+  the render tests, and the data behind it is proven live (§6).
+- **The alert legs** (`offsite_box_fill` / `offsite_box_oversub` operator emails) are NOT fired live: the
+  real pool is nominal (0.2% fill, 0.15× oversub — far from the 80%/2.0× thresholds). The optional §13-step-5
+  live-fire (temporarily lowering a threshold below the live fill) would send ONE real operator email to
+  Viktor — deliberately NOT done unprompted. The alert path is unit + red-proof verified (Group C + the C7
+  operator-only scope). Offered to the operator to run on demand.
 
-Re-grepped at implementation time for all non-test callers of `SetHostDesired`, `BumpHostDesired`,
-`BumpAllHostGenerations`, plus the system-initiated customer-deliverable writers. No forgotten fourth
-caller — every site below is accounted for.
+### 8. Observations
 
-| Site (file:landmark) | Initiator | Plane | Notification after this task | Reason if none |

-| `api/wg.go` `handleRegisterWGPeer` `BumpHostDesired` (~L291) | system (agent registration) | agent | **none (deliberate)** | box's tunnel does not exist until it fetches the WG block — a poke is undeliverable by construction; the agent fast-tick SECONDARY (R-28) owns this leg |
-| `api/wg.go` WG peer delete `BumpHostDesired` (~L422) | operator | agent | **none (deliberate)** | the mutation removes the transport |
-| `pbsdrheal` **Restage** path | system (reconciler) | agent | **none (deliberate)** | no generation bump → the agent's 60 s pbsdr ticker is the pickup path (a poke is a verified no-op); `internal/pbsdrheal/` byte-unchanged |

-### 9. Observations (not acted on)
-
-- **`handlePBSDRReissue` ↔ `ReissuePBSDR` duplication.** The operator button re-implements the reissue
-  atom's tail (reissue → store secret → descriptor bump) instead of calling `ReissuePBSDR`, deliberately,
-  to keep granular per-step HTTP error strings (the "keep in lockstep" comment marks the known
-  duplication). Both now poke after their `SetHostDesired`. Not deduped (per spec forbidden-dedup); if
-  ever unified, the handler's error-string granularity is the constraint to preserve.
-- **`pbsdrProvisionAtom` is poke-free by design** — its two callers poke on success (form path at L186,
-  hook path at the new L312). This keeps the poke at the decision point (blocked vs minted) rather than
-  inside the shared atom, matching the existing L186 structure.
+- **Threshold ruling pending:** warn 80% / crit 90% / oversub 2.0× are Claude's encoding of the starter
+  suggestion; the named `Alerting.OffsiteBox*` keys are the one-line flip when Viktor rules.
+- **Data-vs-snapshot split usefulness:** on the live box `size_snapshots == 0` (restic-only, no Hetzner
+  snapshots) — the split is currently uninformative but free, and will matter if snapshot retention is ever
+  enabled; the panel shows it.
+- The `OffsiteChecker` sibling DOES SaveEvent (the spec's "email-only" aside was inexact); the box checker
+  deliberately does NOT (customer-less scope has no row to key it to) — confirmed the dispatcher's
+  operator-only path handles that (C7).

-| R-5 | Hub: Storage Box box-level aggregate — total BX11 fill, Σ(customer soft quotas), oversubscription ratio, operator alert threshold | M | idea | Per-customer OffsiteChecker exists (hub v0.41). Source: Hetzner Storage Box API (verify Robot-legacy vs. new API endpoint for our box before speccing — 2025 migration); NOT ssh `du` over restic repos. Token → k8s Secret ref. Flips map row G/MISSING |
+| R-5 | Hub: Storage Box box-level aggregate — total fill, Σ(shared soft quotas), oversubscription ratio, operator alert | M | **SHIPPED (hub v0.64.0, 2026-07-17)** | `monitor.OffsiteBoxChecker` (throttled Hetzner GET, no ssh/`du`; the new unified API, Robot-vs-new question resolved at source); fill 80/90% + oversub 2.0× (thresholds pending Viktor's ruling — named config keys); Offsite-tab panel + dashboard tile; scope `"pool-box"` → operator only. **Data pipeline PROVEN-LIVE** (`0.2% full, 2.6 GB of 1.00 TB, Σ 150 GB, 0.15×`). OPEN: UI render unit-only (password-gated), alert emails unit + red-proof only (real pool nominal). See hub v0.64.0 REPORT |
 | R-6 | **Spike: LAN service discovery from the guest** — SSDP multicast (UDP 1900, DLNA), WSD (Windows discovery), mDNS; host-network vs macvlan; is the customer LXC LAN-bridged in appliance deployments? | M | idea | Shared prerequisite for R-7 + R-8. Spike-first: the traps are networking, not Samba/DLNA |
 | R-7 | SMB **server** share (gated on R-6): samba + wsdd, LAN-only binding (never tunnel), user model (single household user first), which roots are shared (dedicated `shares/` vs app userdata — every SMB-writable path needs a backup class), uid-1000 convention, paperless consume flow | L | idea | Flips map row E/MISSING. Alpha-relevant: "my box is a NAS" is a core household expectation |
 | R-8 | DLNA (gated on R-6): validate Jellyfin's built-in DLNA server first; only add minidlna to the catalog if Jellyfin-DLNA fails | S | idea | Don't add catalog weight before proving the cheap path |
