 | **The hub reports LOSS OF VISIBILITY into either off-site store (not just how full it is)** | hub **v0.106.0** (R-339) | **IMPLEMENTED — deliberately NOT proven-live** | Both box checkers count consecutive failed fetch windows and emit `pbsdr_box_unreachable` / `offsite_box_unreachable` (severity `warning`) past a default 3 windows (≈30–45 min), each with a paired `*_recovered` all-clear routed via `recoveredPairedDownTypes` — required because the recoveries are severity `info`, which `severityNotifies` drops. Scopes stay customer-less (`pbsdr-box` / `pool-box`) → operator channel only. Fill logic untouched: a degraded read still drives no band transition. Evidence: `internal/monitor/box_reachability_test.go` + the cross-package wiring test in `internal/notify/`, which asserts an actual operator mail rather than a map entry. **Filed BECAUSE of a measured gap**, not a hypothesis: the 2026-08-18 ep0 outage ran 9 h 37 m with the hub silent | **The gap that remains is R-340**, and it is not small: the ep0 read is the `usage` op, which rides the LOCAL API daemon — the daemon that incident explicitly cleared — so this check would have shown GREEN for that entire outage. It closes "ep0 is unreachable as a host"; it does not close what actually happened. **No live or constructed outage has exercised the emit path**, and one cannot be manufactured against ep0 (Tier 2, protected) |

Design `architecture/11-os-updates.md` §8.1 | **No automatic undo** (a customer guest cannot be snapshotted, R-837 → R-842); existing boxes need the wrapper + sudoers by hand (R-840); host / Docker / kernel lanes not built (R-812, R-835, R-836); `felhom-host-install.sh:2133-2136` still runs no host upgrades |
+| Box operating-system security updates (Proxmox host, guest Debian, Docker engine) | agent v0.141.1, hub v0.131.1 | **PARTIAL — the GUEST and HOST Debian fast lanes are PROVEN-LIVE (2026-10-04), with the fleet view and four operator alarms; Docker and the kernel are MISSING** | Guest: `audits/os-guest-lane-2026-10-04/`. Host + fleet + alarms: `audits/os-host-lane-2026-10-04/` — ring 0 on both demo hosts (demo-felhom 108 Debian host packages, healthy, 0 Proxmox-origin); a 605-package host release approved (TEST wait, then the ruled 24 h + 1 night restored); demo-felhom as ring 1 installed exactly the one host version it lacked; the by-hand host undo proved (`runbooks/os-updates-host-undo.md`); `tunnel_down` / `tunnel_recovered` live. Design `architecture/11-os-updates.md` §8.1–§8.3 | **No automatic undo** (guest: last night's backup, decision 81; host: the by-hand runbook); existing boxes need the wrapper + sudoers by hand (R-840); Docker and kernel lanes not built (R-812, R-835, R-836); a host panic is not restarted (R-851) |
 | **An ENGLISH-SPEAKING household's first hour: download, install, pair, bind, claim, two apps** | controller **v0.259.0** + hub **v0.119.0** + ISO 1.29.0 + the whole catalog | **PROVEN-LIVE on 0.258.0 with one blocker; THE BLOCKER IS FIXED AND PROVEN, THE WALK IS NOT REPEATED** | `audits/DRILL-first-hour-en-0258-2026-09-20.md` — a fresh install 2026-09-20, one intervention (R-494), stop rule not reached. Then `audits/i18n-closing-2026-09-21/live/` — the three blockers fixed and each proven on a live box or in the operator's inbox: the claim page answers English through the real cookie path; the Backup page's tier names follow the language; and the setup mail carries **four plain-ASCII English words** where the drill's carried `képző-szkítia-ásatás`, one day apart in the same inbox. | **R-596, R-597 and R-598 are CLOSED.** What this row still does NOT claim: **the fixed journey has not been walked end to end by a stranger on a fresh install.** Three fixes proven at the endpoint are not an hour proven by a person, and this project's own rule is that fixes are not a journey (see the recovery-journey row). **Also not walked:** the recovery code (needs ep0), backup/restore/remove/power-cut (proven 2026-09-14), and the two Backup-page *warnings* themselves — guest 9201 is healthy and a healthy box renders none, so they are covered by handler render tests, not live. **Verdict: nothing known now stands between an English-speaking tester and their box — and that is a different sentence from "the walk passed".** |
 | **A deletion of a customer's off-site history is NOTICED within a day** | hub **v0.111.0** (R-431) | **IMPLEMENTED — not yet PROVEN-LIVE** | 09-01 | `hub/internal/monitor/offsite.go` — third signal beside FILL and STALENESS. **On the hub deliberately:** a detector on the box is one the deletion can silence. Alarms when the reported count falls by more than HALF and by at least 5, guarded by `StatsKnown` (R-331), the declared `State` (R-204) and run success (R-100). **Threshold reasoned, not invented:** over 12 898 reports every decrease lands on ZERO and predates `stats_known`; in the 380-report `stats_known` window there are none. **ACCEPTANCE: 9 009 real points replayed → ZERO alarms** (`offsite_r431_test.go`, fixture committed). **What PROVEN-LIVE would need and this does NOT have:** a real drop observed on a live box producing a real mail — the live firing done at ship time was driven through the hub's own path with synthetic counts, which is an end-to-end delivery proof, not a proof that a genuine deletion is caught. |
