Teardown verified on ep0, and the two periods I got wrong (R-600)

The customer delete cascade logged "full teardown" while the drill box's WireGuard
peer 10.77.0.5 was still configured on ep0. Checked THERE rather than inferred from
the hub, then watched until it went: gone about 6 minutes later. The mechanism is
asynchronous, not broken; the log line claims a completeness it does not yet have.

Both periods this session inferred from two log lines were wrong — the delete's
staleness window and wgsync's push interval. A period read off two log lines is not
a measurement, and both rows now carry what was actually observed.

 | **R-596** | **[P1-HIGH] The claim page — the FIRST screen an English household touches — is English chrome with HUNGARIAN messages, and two of them are quoted in the guide as English.** FOUND 2026-09-20 on a fresh install by the slice-6 drill, **seen on screen, not read in source**. The page itself is English (*"Set up the server"*, *"Enter the setup code you got by e-mail…"*, *"Set up and sign in"*, *"Did not get the code? Ask for a new one"*). Its MESSAGES are not: a short password answered **„A jelszónak legalább 12 karakter hosszúnak kell lennie"** and a mistyped code answered **„Hibás vagy lejárt kód"**. **`internal/web/claim.go` carries SIXTEEN raw Hungarian literals**, every one of them a message this page shows: L281/L334 („A beállító állapot most nem olvasható…"), L286, L310/L444 („Érvénytelen űrlap…"), L317/L321/L359 („Túl sok próbálkozás — próbáld újra 15 perc múlva."), L338, L362 („Hibás vagy lejárt kód"), L368, L372 („A két jelszó nem egyezik"), L379/L384, L448, L523, L563. **Why every earlier slice missed it:** they are not error VALUES (slice 2 converted 179 of those) and not template text (slice 1 converted that — which is why the chrome IS English); they are composed sentences passed into `handleClaimPage(w, r, <msg>, "")` as page data. **The same shape as R-573's two banners**, one screen earlier in the journey. **It ranks P1 because of WHERE it is:** a household that cannot read „Hibás vagy lejárt kód" cannot tell a typo from a dead code, on the one screen that stands between them and their box — and the English guide, written from the bundle rather than from the screen, promises them *"Wrong or expired code"* and *"Too many attempts — try again in 15 minutes."*, which the product does not say. **Fix shape:** keys for all sixteen, `handleClaimPage` taking a key + args instead of a sentence, and a render case per message in both languages. | **READY — rank P1-HIGH; owner: CC (controller)** |
 | **R-597** | **[P2-MEDIUM] The setup code is three Hungarian words, inside an otherwise fully English e-mail, sent to a household the hub knows is English.** FOUND 2026-09-20 by the slice-6 drill. The mail is English end to end (slice 3 working); the code it carries was **`képző-szkítia-ásatás`** — 20 characters, 3 words, **5 of them outside ASCII** (ő, í, á×2, é). An English speaker must copy three words they cannot read, spell or say aloud, and type them into a box on a keyboard that has no ő. They can paste — until the day they read the code to someone over the telephone, which is precisely what a three-word code is FOR. **The same generator feeds the recovery code (10 words) and the owner passphrase (5 words)**, so the fault is one wordlist wide, not one mail wide: this walk saw the passphrase too and it is Hungarian. **Fix shape:** an English wordlist chosen per `customer.language`, with the same word count and the same entropy, and a test that pins BOTH lists' entropy and that no word in either needs a character outside the reader's keyboard. **Not a rename of the existing words** — a second list. | **READY — rank P2-MEDIUM; owner: CC (hub)** |
 | **R-598** | **[P2-MEDIUM] The Backup page's two protection warnings — the ones that say whether the household's files are safe — are Hungarian on an English dashboard.** FOUND 2026-09-20 by the slice-6 drill on a fresh box, and confirmed on the demo box. Of 73 lines on `/backups` exactly four are Hungarian: **„Csak egy másolat készül (nincs második meghajtó) — a 3-2-1 mentéshez csatlakoztasson egy második meghajtót vagy offsite tárolót"**, **„A rendszermentés jelenleg ugyanazon a lemezen van, mint a rendszer — így hibás fájlok ellen véd, lemezhiba ellen nem"**, and the two backup-target names **„Helyi tároló (local)"** and **„Biztonsági szerver – külön hardver (PBS)"**. They come from `internal/web/backup_handlers.go` (12 Hungarian literals) and `internal/web/backup_target_offer.go` (10) — again composed sentences handed to the page, the R-573/R-596 shape. **It matters more than its line count:** those two warnings are the only place the product tells a household that one copy on one disk is not protection, and the volunteer guide's §9 sends every tester to exactly this page to read exactly these two sentences. **Fix shape:** keys + args for both files, with the retrieval-promise gate run over the English (these sentences are about what a backup does and does not protect). | **READY — rank P2-MEDIUM; owner: CC (controller)** |
-| **R-599** | **[P3-LOW] A drill's teardown is blocked for 30 minutes by design, and nothing says so.** FOUND 2026-09-20 tearing the slice-6 drill down. VM destroyed at 17:12Z; the hub then refused **both** `POST /configs/<id>/delete` (409, *host … is ONLINE*) and the host delete (`deletable:false`) — correctly, because an online host would receive permanent 401s. But "online" is not a liveness probe: it is a **30-minute report-staleness window** (`monitor/host_staleness.go`, `threshold` default 30m). A machine that no longer exists therefore reads ONLINE for half an hour. **The consequence is not theoretical:** a session that destroys its VM and then tears down the hub side walks away believing the delete failed, or leaves the customer behind — and the 2026-09-14 drill's teardown had the same shape without recording this. **Fix shape (smallest first):** the 409 body says *how long* it will refuse ("the last report was N minutes ago; deletion opens at HH:MM"), and `runbooks/target-selection.md`'s drill section names the wait. A force flag is NOT proposed — the refusal is right, only silent about its own clock. | **READY — rank P3-LOW; owner: CC (hub)** |

But "online" is not a liveness probe: it is a **report-staleness window**, and the window is **45 minutes** — `manifests/hub.yaml` sets `alerting.stale_threshold: "45m"`, which `hostStatus()` reads (`ok` under it, `stale` over, `down` at 2x). A machine that no longer exists therefore reads ONLINE for three quarters of an hour. **Measured the boring way, and worth recording:** this row first said 30 minutes, because `monitor/host_staleness.go`'s literal default says 30m — the DEPLOYED value is in the manifest, and the 409s kept coming after the half hour was up. Reading a default and calling it the live value is the same mistake in a smaller coat. **The consequence is not theoretical:** a session that destroys its VM and then tears down the hub side walks away believing the delete failed, or leaves the customer behind — and the 2026-09-14 drill's teardown had the same shape without recording this. **Fix shape (smallest first):** the 409 body says *how long* it will refuse ("the last report was N minutes ago; deletion opens at HH:MM"), and `runbooks/target-selection.md`'s drill section names the wait.

+| **R-600** | **[P2-MEDIUM] "Full teardown" is logged while the deleted box's WireGuard peer is still configured on ep0.** FOUND 2026-09-20 by the slice-6 drill's teardown, **measured on ep0 rather than inferred from the hub**. The customer delete cascade finished at 19:41:54 with `customer DELETE cascade COMPLETE for drill-en-0920 (journal #18) — full teardown`, and every hub-side row was gone (0 configs, 0 hosts, 17 residue rows purged, PBS tenancy deprovisioned, escrow demoted). **Three minutes later `wg show wg0 allowed-ips` on ep0 still listed `10.77.0.5/32`** — the drill box's peer — because `wgsync` pushes on its own cycle. **Watched to the end rather than assumed: the peer was gone by 17:47:46Z — it outlived the *full teardown* line by about 6 minutes.** (My first estimate said ~35, read off the gap between two log lines; the sync runs oftener and only LOGS when something changes. That is the second time in this session that a period inferred from two log lines was wrong — the other was the delete's own staleness window. **A period read off two log lines is not a measurement.**) **The 2026-09-14 drill's findings say "the teardown removes it through the host delete"; measured, the host delete removes the hub's RECORD and the peer goes on the next push.** The mechanism is not broken — it is asynchronous, and the log line claims a completeness it does not yet have. **Why it is P2 rather than P3:** a session that tears down, reads *full teardown*, and leaves is the normal case; the peer outlives it by minutes, and the third teardown layer is the one the workspace rules single out as the one that gets forgotten. Six minutes is short — but the session that reads *full teardown* and leaves has no way to know it is six and not six hours. **Fix shape (smallest first):** the cascade triggers a wgsync push before it logs COMPLETE, or the log line says what is still pending and when ("wg peer removal queued; next push in N min"). A session should not have to read ep0 to know whether a teardown finished. | **READY - rank P2-MEDIUM; owner: CC (hub)** |
 | **R-537** | **[P1-HIGH] The app-backup page labels the tier-1 backup „DB + Konfig + Adatok" and prints the app's data-drive size next to it — but the tier-1 unit contains NO drive-side app data at all.** MEASURED 2026-09-16 on the drill box (fresh install, controller 0.243.0, one drive, tier 2 and tier 3 both „Nincs beállítva"): five photos (3 000 000 B) were uploaded into Nextcloud through its own WebDAV interface, then the customer-visible „Mentés most" was pressed (`POST /api/backup/run` → 200, the unit grew 25 337 B → 978 MB). The resulting unit's `manifest.json` lists `db-dumps` + three **docker volume** dumps and nothing else; listing the 781 MB `nextcloud_nextcloud_html.tar` (29 346 entries, positive control `version.php` = 3 hits) gives **`Fotok` = 0 and `nyaralas` = 0**, and `./data/` is the empty bind-mount point. A `find` over the whole `backups/` tree for `*appdata*` / `*Fotok*` returns nothing. The page nevertheless renders „1. mentés … DB + Konfig + Adatok" and „Nextcloud Adatlemez 65.1 MB" — a size measured on exactly the data it does not copy (`internal/web/handlers.go:1176-1178`, `BackupContents`). **This is a truth defect, not a design defect:** `07-backup-architecture.md` §6.2 places nextcloud's file leg at **Tier 2 and Tier 3 only**, and its „[FACT] What the whole-guest tiers do NOT carry" says `mp8 /mnt/felhom-drives` is out of vzdump scope (confirmed live: „excluding bind mount point mp8 … (not a volume)"). So on a one-drive box with no off-site tier — the state every fresh install starts in — the household's files are in **no backup**, while the page says „Adatok". Same family as R-517/R-518. **Fix shape:** render tier-1 contents from the capture set actually written (`ComputeCaptureSet`), so a unit with no file leg reads „DB + Konfig" and the drive size is not shown beside it; and say on the page that the app's files need tier 2 or tier 3. Evidence: `audits/evidence-drill-0243-2026-09-16/phase2-f10.txt`. **CLOSED 2026-09-16 — controller v0.244.0, proven live.** The contents label is computed PER TIER from what that tier captures: Tier 1 says „Adatok" only when the app's data really is in the volumes the unit captured, and a class-A app carries one sentence saying where its files ARE protected. Proven on demo-hp through the page the customer opens: Paperless-ngx reads „1. mentés … DB + Konfig" with „Az alkalmazás fájljait a távoli másolat (és a második meghajtó) védi …", while its „2. mentés" row still reads „DB + Konfig + Adatok". Red-proof: restoring the old app-shaped label fails `TestAppBackupRows_Tier1LabelDoesNotClaimFilesItCannotHold`. **RE-PROVEN 2026-09-16 on a FRESH box** (installed from the built ISO 1.28.0, controller 0.244.0, off-site on by default): the Nextcloud row read „1. mentés … DB + Konfig" with the new sentence, „2. mentés … Nincs 2. (off-drive) másolat", „3. mentés Sikeres restic → …your-storagebox.de"; „DB + Konfig + Adatok" appeared ZERO times while the local unit held no file leg. | **CLOSED 2026-09-16 — controller v0.244.0 (proven live on demo-hp)** |
 | **R-538** | **[P1-HIGH] A tier-1 app restore reports plain success and leaves Nextcloud listing files whose bytes were never in the backup — and it destroys the app's own trash, the customer's last copy.** MEASURED 2026-09-16 on the drill box, F10 („a child deletes the photo folder"): the five photos were deleted through Nextcloud (DELETE 204, PROPFIND 404), then restored through the page exactly as a customer would (`POST /backup/restore` `stack_name=nextcloud` `snapshot_id=helyi` → 302, finished in **35 s**, „A(z) nextcloud: 3 adatkötet és az adatbázis visszaállítva — az alkalmazás újraindult."). Afterwards the folder is back and **lists all five photos**, and **none of them opens**: `GET nyaralas-1..5` = 404 / 503×4 with `Sabre\DAV\Exception\NotFound`, while the positive controls at the same moment pass (`status.php` 200, WebDAV PUT 201, GET 200). Cause: the replayed MariaDB dump (11:01:45Z) knows the photos, the bytes live on `mp8` and were never captured (R-537). **Worse:** the bytes were still on the drive in Nextcloud's own trash (`appdata/nextcloud/admin/files_trashbin/files/Fotok.d1789556707/nyaralas-1..5.jpg`, all five present) and the restored database no longer references them — the trash listing comes back **empty**, so „restore from trash", the one route that would have worked, is gone. The customer is left with five unopenable photos, a success message, and no warning. **Fix shape:** before replaying a database whose app has an uncaptured file leg, refuse or warn („ennek az alkalmazásnak a fájljai nincsenek ebben a mentésben — a visszaállítás után a fájlok hiányozni fognak"); and never present a DB-only restore of a class-A app as a complete one. Evidence: `audits/evidence-drill-0243-2026-09-16/phase2-f10.txt`. **CLOSED 2026-09-16 — controller v0.244.0, proven live.** A unit restore refuses before anything is touched when the unit cannot return the app's drive-side files, and names the route that can. Fired live on demo-hp: `POST /backup/restore` for paperless-ngx → 302 with „Ez a mentés nem tartalmazza az alkalmazás fájljait, ezért nem állítjuk vissza az adatbázist föléjük — a fájlok így a helyükön maradnak. A fájlok a távoli másolatból állíthatók vissza …", and the app read `running` before AND after, so nothing was stopped and no trash was made unreachable. The database-and-settings-only path exists as a separately worded second step. Red-proof: disabling the guard fails `TestUnitRestore_RefusesWhenTheUnitCannotHoldTheFiles`. **RE-PROVEN 2026-09-16 on a FRESH box, and this time the refusal had somewhere to point:** after five photos were deleted, `POST /backup/restore` was refused with „…a fájlok így a helyükön maradnak. A fájlok a távoli másolatból állíthatók vissza: … „Teljes visszaállítás (fájlok + adatbázis)"", the app read `running` before AND after, and the wastebasket was untouched. The off-site route then returned all five photos — 200 with the exact uploaded sizes and sha256 IDENTICAL to the originals, 5/5, with a negative control. Evidence: `audits/evidence-backup-promise-2026-09-16/phaseE-photos.txt`. | **CLOSED 2026-09-16 — controller v0.244.0 (proven live on demo-hp)** |

R-513 closed the default-password hole with a generated password; a household still has two logins. **What it needs:** a spike on a scratch guest — forwardAuth to the controller session, and what FileBrowser Quantum does with a trusted header. | **READY — rank P3-LOW; owner: CC (spike)** |
