+and if the app happens to need no required field, it is now installed on the box.
+
+- 2026-09-17: a session probing the required-field refusal picked an app that needed no field. It
+  installed. Recorded in `STATUS.md`.
+- 2026-09-18: a session that had read that record, and had a prompt line forbidding it, did the same
+  thing with `vaultwarden`. Recorded in
+  `documentation/audits/i18n-slice2-2026-09-18/B/live/README.md`.
+
+The lesson that sticks is narrower than "pick a different app": **the deploy endpoint cannot be used
+to probe a refusal at all.**
+
+**Instead, use a request that is refused BEFORE anything is created:**
+
+| you want to see | use |
+|---|---|
+| a deploy-path refusal | an app that is ALREADY installed → `409 already deployed` |
+| a not-found path | a name that exists nowhere → `404` |
+| a validator's sentence | `POST /sharing/shares` with a bad name, `POST /api/disks/assign` with a bad mount point — both refuse before they write |
+| a protected-resource refusal | `POST /api/stacks/felhom-controller/remove` → `403` |
+
+## If a probe does create something, remove it through the product
+
+Not by hand, and not by `docker rm`: stop it, then `POST /api/stacks/<name>/remove` with
+`remove_hdd_data` and `remove_backups`, and then **verify** — no container, no `/opt/felhom/stacks/<name>`,
+no volume. Say in the report that it happened. A tidy-up nobody is told about is how the next session
+learns nothing.
+
+## The general shape
+
+**Before sending anything to a live box, ask which side of the write the refusal happens on.** A
+refusal that comes after the write is not a refusal you can probe — it is a change you are making.

+# Unprompted work — rules for any session without a task file
+
+> Goal sessions, nightly sessions, "work the register" sessions. **A session that starts from
+> `/goal` or a standing brief inherits these rules exactly as it inherits the gates.** They are the
+> part of `PROMPT-TEMPLATE.md` that a task file used to carry and a goal does not. Same wording lives
+> in all three repos' `.claude/rules/`; change it in all three or in none.
+
+## 1. What you may pick up on your own
+
+- A register row **you or another CC session filed**, with owner CC, at P3 or a bounded P2, that
+  needs **no operator decision**, touches **no customer data by design**, and introduces **no
+  mechanism nobody has measured**. Smallest first.
+- A defect you find while exercising the product, filed as a row **before** you fix it.
+- Hygiene: register compression, stale citations, rows with no owner, documents that contradict
+  live source.
+
+**Not yours, ever, without a task file or an operator word:** money; anything that changes risk to
+customer data; anything that changes a promise the product makes to a customer; anything that
+reverses a documented design decision (`documentation/architecture/` — a design decision is not a
+defect, R-370); anything on DooPlex, Peti's box or ep0; baking or vouching a golden; promoting a
+catalog version; a new external dependency.
+
+## 2. When you may decide instead of ask (operator grant, 2026-09-14)
+
+You may take a decision yourself when **all** of these hold: the architecture folder and the register
+give a clear direction; your choice follows that direction; it is reversible without customer-data
+risk; and you can write it in the `09-update-architecture.md` §3 shape — one answerable sentence, the
+options, what each costs, why this one. **Then record it** as a dated decision in `CONTEXT.md` and
+the owning architecture document, tagged *decided by CC unattended — operator may reverse*, and put
+it **first** in the morning note. A decision you cannot write in that shape is one you do not take.
+
+## 3. The discipline a task file used to carry
+
+1. **Baselines first.** Read each repo's `main` hash and version from live source before touching it.
+2. **Read the architecture document for the area, and name it** in the report, before any claim.
+3. **Red-proof every correctness fix.** A test never seen failing has not been shown to test anything.
+4. **Live-validate on a Tier-0 box** through the endpoints the UI invokes. `demo-hp` is `ssh hp`.
+   Throwaway apps only; the standing apps and `bentopdf` stay.
+5. **Evidence off the machine at the end of each phase**, before any revert (R-320).
+6. **One release per repo per session**, with a CHANGELOG entry (controller: with its `MinAgent`
+   line), REPORT overwritten, floor raised to deliver it. **No golden unless a drill or fresh install
+   needs one** (the waiver, R-468). **No `--no-verify`.**
+7. **An enumerated gap becomes a row in the same session.** Prose is not a record.
+8. **Hungarian text is searched with ASCII fragments**, with a positive and a negative control.
+9. **Never leave a half-state.** If time runs out, revert to clean and say what was reverted.
+10. **Teardown, three layers, stated** — machine, host, hub — or "provisioned nothing".
+
+## 4. The morning note
+
+One screen, plain language, in this order: **decisions you took** (§2) first; what you exercised;
+what broke and whether you fixed it; rows opened and closed with the register size before and after;
+what needs the operator, each with what happens if they do nothing. No file paths, no function
+names, no row numbers as the subject of a sentence.

+dashboard, the box reports it and the hub's e-mails follow; (3) a missing English line shows the
+Hungarian one and is counted — never a key or a blank; (4) the first-boot wizard is out of scope and
+obsolete — deletion is R-554.
+
+**Decided by CC in the spike — operator may reverse:** (5) the mechanism is a flat bundle per
+language EXPANDED into the template before `html/template` parses it (a runtime `T` func changes
+Hungarian bytes through the escaper); (6) the language switch is hidden on Hungarian pages until the
+remaining templates are converted (R-556).
+
+**Mechanism, shipped controller v0.247.0:** `internal/i18n/locales/{hu,en}.json`; one template set per
+language; `settings.json` `language`; `POST /settings/language`; `?lang=`; report field `language`
+(allowlisted in `wire_contract_gate.py` until slice 3 reads it). **The release gate for every slice is
+`TestI18nParity`**: Hungarian renders vs fixtures captured from UNCONVERTED templates — never
+regenerate them to make a conversion pass. Live on demo-hp: Hungarian pages identical to 0.246.0 apart
+from version and CSRF token. **Ruled the same evening:** 1b — the console banner and the download page ARE in
+scope (R-559 unblocked); 7 — interface nouns translate (Launcher, Dashboard, Backup); app names and „Felhom" stay. Plan and costs: 10 §10; rows R-553..R-562, **R-553 first** (four
+places decide behaviour by Hungarian wording).
+
+## Decisions 2026-09-17 — the chaos-night fixes (operator rulings)
+
+**Ruling A (R-549): the quiet-box alarm waits three report cycles.** `alerting.stale_threshold` 30 m →
+**45 m**; `node_down`/`host_down` at 90 m. Mechanism: configuration in `manifests/hub.yaml`, plus hub
+v0.117.0 making the dashboard's customer status read the same value (it was hardcoded). Cost accepted:
+a dead box pages 15 minutes later. `08-alarm-ladder.md` §6.2.
+
+**Ruling „fix" (R-550): the restore record is persisted — a reversal of the in-memory design, for the
+restore record only.** Controller v0.246.0, `restore-status.json` in DataDir; `restore_interrupted`
+(warning, household). Notification cooldowns stay in memory. `07-backup-architecture.md` §3.
+
+**R-546 (no new ruling — a fix inside R-543's):** the recovery-code reminder and the escrow page wait for
+the agent's own preflight `ok`; the start API refuses before staging. Controller v0.246.0.
+
+**Ruling 3 of 2026-09-16, built (R-539):** the slow crash-loop counter, agent v0.132.0 / hub v0.117.0,
+signed to demo-hp and the N100 by CC under ruling 1 of 2026-09-16. `03-host-agent.md`.
+
+## Decisions 2026-09-16 (evening) — the recovery code: the household is asked, the page says „szünetel"
+
+**No new ruling. One correction to the record, from the operator (2026-09-16):** the note saying a
+rebuilt box needs zero presses for its off-site setup was WRONG. The press exists by the F-14 ruling
+of 2026-07-13 — the hub re-issues by itself **only** when the previous box was deleted through the
+acknowledged flow; otherwise `handleHostEnroll` reuses the existing record and mints nothing, and the
+operator presses „Re-issue PBS credentials" once (`hub/internal/web/pbsdr.go`). That ruling stands and
+is now written into `runbooks/day0-install.md` §A.2b, where it was missing.
+
+**R-543 CLOSED — controller v0.245.0.** The tier-3 pause is the zero-knowledge escrow design and was
+not touched. Two copy changes only:
+
+- **`internal/web/escrow_banner.go`** — the R-241 reminder bar, SECOND INSTANCE. `escrowPaused()`
+  reads the same two facts `tier3State` reads (`backupMgr.OffboxConfigured()` and
+  `settings.GetOffboxTarget().EscrowState != "escrowed"`), so the bar and the app rows cannot
+  disagree. **It hangs off `executeTemplate` (server.go), the single render choke point** — not the
+  three `addRecoveryBanner` call sites, because a per-handler helper reaches only the pages someone
+  remembered (the seam-built-but-never-wired class). Login and claim render through
+  `s.tmpl.ExecuteTemplate` directly and never pass through it; `hasAdminSession()` (mirroring
+  `RequireAuth`, legacy-open included) keeps it off the public `/s/<token>` share page. Dismissal:
+  session cookie `felhom_escrow_banner`, no MaxAge/Expires, route `/backup/escrow/banner/dismiss`.
+- **`driveFilesNoteFor` (`internal/web/backup_page_state.go`)** — the tier-1 file sentence takes
+  `tier3State`'s OWN vocabulary instead of the app's shape, and returns (note, linkHref, linkText) so
+  the template renders a real anchor. Assigned at the END of the app-row loop, where `Tier3State` and
+  `Tier2Configured` are both already resolved.
+
+**Trap re-learned, twice in one session, and worth the line:** inside a guest the controller's data
+directory is `/var/lib/docker/volumes/felhom-controller-data/_data/data`; `/opt/docker/felhom-controller/data`
+is the CONTAINER's view of the same files. A teardown script using the container path from a guest
+shell printed „offbox dir now: ABSENT" — true of a path that never existed, false of the thing being
+claimed — and left the target fully configured. Also: the controller answers on the container address
+`172.17.0.2:8080` with the mandatory `Host` header; it is NOT on the guest's `127.0.0.1`, and neither
+guest is reachable from DooPlex at all.
+
+**New row:** R-545 (P3) — nothing un-configures an off-site target; `/backup/offbox/reset` refuses
+unless the repo is ORPHANED and means „start a new remote backup", not „forget this destination".
+
+## Decisions 2026-09-16 (afternoon) — the backup promise: files protected from day one
+
+**Ruling: the off-site copy is ON for every customer from day one** — shared (a sub-account on the
+pool box), **100 GB soft quota** prefilled, the checkbox kept so an operator can opt a customer out.
+Hub **v0.116.0**, `handleConfigNewForm`. The quota is prefilled because `monitor/offsite.go` only
+warns on a filling store when `quota_gb > 0`. Recorded in `07-backup-architecture.md` §6.
+
+**Ruling: the ep0 endpoint token gets `Datastore.Modify`**, narrowly — the hub's tenantsync auth-id
+only, on `/datastore/felhom-offsite` only — so the R-511 adopt path stops being inert (R-534).
+
+**Ruling: the supervisor gets a second, SLOWER counter** — N restarts in 24 h raise a warning — because
+the 3-in-15-minutes brake catches a fast crash loop and is blind to a slow one (measured: four
+restarts 20 minutes apart, none accumulating, the only trace an `info` event that mails nobody,
+R-531). **Not built in this task** — it is a row for the nightly.
+
+**What shipped with them (controller v0.244.0):** the app-backup page's contents label is now
+**per tier** and a Tier-1 unit no longer claims „Adatok" for files it cannot hold (R-537); a unit
+restore **refuses** rather than replaying a database over files that were never captured, and points
+at the route that can return them (R-538); `app_deployed` moved from the deploy's ACCEPTANCE to its
+completion, with `app_deploy_started` and `app_deploy_failed` as the honest pair (R-536).
+
+## Decision 2026-09-16 — CC may sign `agent_update` jobs until the first paying customer (operator ruling 1)
+
+The operational signing key (`felhom-op-1`) and the recovery key stay on DooPlex at
+`/mnt/5_hdd/felhom.eu/felhom-op-{operational,rec-recovery}` (+ `felhom_op_ed25519`), **mode 0600, owner
+`kisfenyo`** (R-533). Until the first PAYING customer exists — testers do not count — CC may sign
+`agent_update` ops with them, per box, as it did for `demo-hp-bb76ea` on 2026-09-15 and
+`demo-felhom-8363b5` on 2026-09-16. **Revisit on the first sale.** A fleet-wide rollout step is still
+undesigned (R-530). Also this day: `host_stale` / `host_down` / `host_recovered` join the `node_*`
+cooldown bypass (ruling 2, hub v0.115.0, `08-alarm-ladder.md` §6.2).
+
+## Decision 2026-09-15 — „box is down" mail skips the one-hour quiet rule (operator ruling, decision A)
+
+`node_stale`, `node_down`, `node_recovered` bypass the 1-hour operator cooldown, with a 5-minute
+dedupe (hub v0.114.0). Reverses the documented design for those three types; recorded in
+`documentation/architecture/08-alarm-ladder.md` §6.2. Reason: BIGNIGHT F9 — a 33-minute dead box whose
+`node_stale` and `node_recovered` mails were both suppressed by an earlier incident's cooldown. Same day,
+also the operator's: the self-bind link goes out whenever a customer waits for a box (05 §13).
+
+## A customer's domain is their own, and the public installer stays interactive (2026-09-14, R-494 / R-495)
+
+**Two operator rulings, both 2026-09-14.**
+
+1. **Every customer has their own domain, never a name under `felhom.eu`.** Free Cloudflare certificates
+   do not cover nested names; the domain (a few thousand forints a year) is included in the price. The
+   operator creates the tunnel per day-0 A.1; R-494 is narrowed to "the hub could create it" (P3).
+   Home: `architecture/01-topology-and-trust.md` §networking.
+2. **The public ISO keeps the interactive Proxmox installer.** Offered an install-time rule ("use the only
+   internal disk, otherwise stop"), the operator kept the 2026-07-31 ruling: a person chooses the disk.
+   Why it was offered and not built: the auto-installer has no local chooser or stop page; a runtime rule
+   needs either an HTTP answer service or surgery inside the Proxmox installer, and USB-drive detection
+   was measured unsafe by udev property (SPIKE-universal-iso-1). Consequence, stated so it is not
+   re-litigated: **the installer's own screens stay English**; the Felhom-written text around them
+   (menu, console, first-boot screens) is Hungarian, and the volunteer guide answers each installer
+   screen. Release gate G14–G16. The spike that would inform a reversal is R-503.
+
+**Decisions a later session must not re-derive:** the ISO's "never engaged" auto-install is not a
+defect — the release build has no answer file by construction (G1); `pvebanner.service` rewrites
+`/etc/issue` on every boot, so a console fix must mask it (ISO v1.27.0).
+
+## The Update button is a guarded job, and the route back is the restore (2026-09-13, update arc slice 4 — R-448 / R-443 / R-439)
+
+**Shipped** in controller v0.237.0 (job) + v0.238.0 (page) + v0.238.1 (nightly-leg fix), **proven live**
+on demo-hp — `documentation/audits/slice4-2026-09-13/`, design `09-update-architecture.md` §6.1.
+
+**Decisions a later session must not re-derive:**
+- **The precondition is the existing verified backup** (ruling 2026-09-02) **on ANY tier** (ruling
+  2026-09-13, controller v0.239.0, R-475 CLOSED): `backup.Manager.UpdateRestorePoints` walks Tier 2 →
+  Tier 1 → Tier 3 and the update leans on the first copy younger than `backup_max_age`; nothing
+  anywhere → back up first. `Tier2UnitRestorePoint` stays the Tier-2 half and the page's predicate.
+- **Age a copy by its last SUCCESSFUL Tier-2 copy, never by the unit manifest's `created_at`** — measured:
+  the manifest moves only when the definition changes (R-476 is the page's side of this).
+- **No automatic rollback** — measured per-app in `SPIKE-upgrade-test-2026-09-06`. Health failure → stop +
+  HOLD (`RestoreHold.Reason=update_failed`, same store and gate as R-379); the hold names the copy; a
+  successful unit restore lifts it.
+- **Anything that writes a restore point skips an app that is held OR updating** (capture, Tier 2, volume
+  dump) — the updating half was found live (v0.238.1).
+- **Removal keeps the backups AND the Tier-2 record unless the customer asked for the backups to go**
+  (v0.240.0, R-486/R-474). A removal that forgets the record makes an intact mirror unrestorable — that
+  was live until v0.239.0. The first nightly rotation (adventurelog, 2026-09-13) found it.
+- **A bind-data app's route back is off-site before its own unit, and the hold names what the copy
+  holds** (operator ruling 2026-09-13, R-479, controller v0.241.0). The unit of such an app holds the
+  definition and the database dumps, not the files. Volume-data apps keep the v0.239.0 order.
+- **One host, one customer** (schema: `hosts.host_id` PK, one `customer_id`; one agent per box). A
+  scratch guest "enrolled as its own customer" on a box that already belongs to a customer is not
+  something the product can do (R-481, 2026-09-13); a second guest of the same customer is.
+- **The scratch guest is LXC 9202 on demo-hp and it persists** (operator ruling option 1, built
+  2026-09-13 night, R-481 CLOSED). A second guest of the demo-hp customer, restored from the vouched
+  golden onto the NVMe `dir` storage at `/mnt/hdd_1`, hub OFF, tunnel OFF, agent OFF, off-site OFF,
+  self-update OFF — so the floor does not reach it and its controller image is set by hand in
+  `/etc/felhom-controller-image` (the one place hand-setting is allowed). Never bind the real data
+  drive into it; never start cloudflared there (a second connector would serve the public domain).
+  Two choices were CC's and are reversible — decided by CC unattended, operator may reverse: no
+  data-drive bind, no tunnel. Reach, shape and rebuild recipe: `operations/nodes.md`.
+- **The local backup lists are keyed on the DRIVES, not on what is deployed** (controller v0.242.0,
+  R-487 — the same rule R-237 set for the off-site list). A removed app whose unit was kept is listed
+  with its restore; a unit on a data drive is opened where it sits.
+- **A release reaches the fleet by floor between golden bakes when its MinAgent is declared with the
+  floor** (ruling 2026-09-13, hub v0.112.0, R-472 CLOSED). An undeclared floor above the golden is still
+  held, and the forms refuse it. v0.239.0 arrived on both demo boxes this way in ~15 s. Never hand-deploy
+  a release to route around this — the floor IS the delivery.
+
+## Goldens move to a CADENCE, and the gate learns to read a dated waiver (2026-09-13, R-468 / R-242 / R-467)
+
+**The ruling (operator, 2026-09-13):** *bake on a cadence — weekly, and always before any drill or
+fresh install — not per release.* **The reason:** `golden_currency_gate.py` trips on every release by
+design, and in August that produced **25 goldens in 26 days** plus thirteen declared `--no-verify`
+bypasses (R-404/R-417). A guard bypassed that often teaches everyone to bypass it. Every release still
+raises the FLOOR, so the demo boxes keep getting each release in ~20 s; only the golden — which
+protects a fresh install and nothing else — moves to a cadence.
+**⚠ CORRECTED THE SAME DAY (R-472): the hub held any floor above the vouched golden, so releases between bakes reached the demo boxes only by hand-deploy. RESOLVED the same afternoon (hub v0.112.0): a floor above the golden is served when saved with the release's declared MinAgent.**
+
+**The mechanism, because a rule without one is a wish (R-242 recurred the day after it was written):**
+`documentation/tests/golden-waiver.yml` — `issued`, `expires` (≤ 14 days, enforced by the gate's
+`WAIVER_MAX_DAYS`), `reason`, `register_row`. Valid → a golden BEHIND the record is a loud ADVISORY,
+exit 0. Expired → red again, naming the date. **Never covers an UNRECORDED golden (R-385)** — that is
+not a cadence choice. Malformed in any way → exit 2, never 0, never silently ignored; the R-421 decoy
+(a file saying only `expires`) is refused. The register is read for ONE fact — does the row exist.
+`GOLDEN_GATE_*` env vars are a test seam (where it reads, never what it decides). Tests: cases 5–15.
+Cadence: `RUNBOOK-manual-build.md` §4.2 and this repo's end-of-session checklist. **Pre-customer: the
+first external install retires the waiver.** **R-242's vouch half is untouched and still open.**
+
+**The last per-release bake:** golden **0.236.0** baked, round-tripped, vouched and the floor raised
+the same day (`documentation/tests/golden-0.236.0-2026-09-13/`) — it carried four unbaked releases
+(R-467). The waiver was issued AFTER that bake landed, not over it.
+
+**Same day, the database engine:** every `mariadb:` sidecar carries `MARIADB_AUTO_UPGRADE=1` (R-459
+closed; `09-update-architecture.md` §3 decision 5) and `app-catalog-felhom.eu/scripts/check-engine-major.py`
+holds every engine inside its major until Slice 4 (R-448) ships — removal tracked as **R-469**.
+
+## The record told a worse story than the truth for two months, and my own probe is why (2026-09-01, R-429 / R-95 / R-431)
+
+**THREE RULINGS.**
+
+**1. A correct instrument pointed at the wrong subject produces a confident wrong answer, and the
+controls cannot save you.** The 2026-08-31/09-01 spike probed for a directory called `.snapshots` and
+reported *"the safety net cannot be seen from the box"*. Its positive and negative controls were
+sound. **The vendor documents the path as `/.zfs/snapshot`.** So `not found` was true and meant
+nothing, and the register carried "the exposure is unbounded" on the strength of it. Re-probed at the
+documented path: `/.zfs` lists from inside the jail, and **a write into `/.zfs/snapshot` is REFUSED**
+(`dest open …: Failure`) while the identical write to the account home succeeds. **Controls prove the
+instrument works; they say nothing about whether it is aimed at the question.** Cite the vendor before
+asserting a mechanism — the task that set the spike asserted it without a citation, and I did not check.
+
+**2. The real R-95 is much smaller than two months of register text.** The box can delete its own
+**live** repository, but it **cannot write to the daily snapshots of it** — measured, both boxes. So a
+deletion costs at most the data written since the last daily snapshot, and the rest comes back **file
+by file**, one customer at a time, with no effect on anyone else. **Not open-ended loss.** Two limits
+kept honest: a sub-account sees the snapshot directory EMPTY, so per-file recovery is **operator-only
+today** (R-432), and a panel-driven restore rolls back the whole Storage Box. **R-95's ranking is
+Viktor's** — it has been #1 since July on the old story.
+
+**3. Detection belongs on the HUB, not the box, and the threshold is reasoned rather than invented.**
+The event being detected is a box deleting its own backups, so a detector living on that box is one
+the same event can silence. The hub already receives the count and keeps the history.
+**The measurement is the interesting part:** across 12 898 reports (2026-06-05 → 2026-09-01) every one
+of the nine decreases lands exactly on **zero**, and every one predates `stats_known` — they are the
+R-331 shape, a zero meaning *unmeasured*, several carrying a declared `State` that says so outright.
+In the 380-report window where `stats_known` is true there are **zero** decreases. **So observed churn
+gave nothing to calibrate against, and saying so beats inventing a number (R-401).** The threshold
+therefore comes from what retention *can* do: keeping 7 daily + 4 weekly + 6 monthly per group means
+it **cannot halve a total**, while a mass deletion goes to ~0 — hence *more than half, and at least
+five*. Three pre-conditions guard it, each with a scar: `StatsKnown` (R-331), the declared `State`
+(R-204), and run success (R-100, whose lesson lives in that very file). **Acceptance: 9 009 real
+report points replayed → zero alarms.**
+
+## The checks were the one thing nothing checked — 16 of 29 could be fooled by a label (2026-09-01, R-421)
+
+**THE CLASS: an instrument that matches a LABEL rather than the fact it names.** Five instances, and
+every single one was found by accident, by someone looking at something else: R-410 (a `mkdir` turned
+the release gate green), R-400 (seven debug controls answering nothing), R-378 (a status word inside a
+longer sentence), R-419 (a phrase inside prose — including prose stating the marker was absent), R-94
+(a test comparing a constant to itself). **The gates enforce every other rule in this project,
+including the rule that findings must be written down. Nothing had ever checked the gates.**
+
+**The method, and it is the transferable part: write the decoy.** For each gate, construct the label
+without the fact — a directory with the right name and no bake log, a handler case that exists only
+in a comment, a note whose prose mentions the marker it lacks — run the gate, and record what it
+says. **A last column answered from reading is worth nothing**; that is precisely how all five hid.
+
+**Result: 29 scripts, 19 sound, 4 holes left open with rows, 6 that no plausible decoy could be built
+for and are named as UNTESTED rather than called sound.** Sixteen were fooled; ten were fixed the
+same day.
+
+**The largest single cause was mundane and worth remembering: SCOPE IS A FACT TOO.** Eight gates
+decided what to look at with `os.listdir` — one directory level. Every one was green *and correct*,
+because no subdirectory exists today; every one would have gone blind the moment anyone added
+`templates/partials/`, which is an ordinary act. `mojibake` and `docker-v` already used `os.walk`,
+caught the identical planted file, and are the control that proves the cause was the listing and not
+the decoy. **Prefer `os.walk` over `os.listdir`, and a glob over a hand-maintained list of files** —
+three of the four remaining holes (R-423 `PAGES`, R-425 `FILES`, and R-410 itself) are hand-maintained
+lists that silently narrowed as the thing they described grew.
+
+**A decoy nobody would write proves nothing, and saying so is a result.** Five of mine were withdrawn
+as illegitimate rather than counted — an inert Compose `x-` field, a CHANGELOG heading that did not
+actually hide the release, a half-built decoy that left the real call in place, a malformed table row
+that convicted for a structural reason, and several planted files carrying nothing the gate hunts for.
+Manufacturing a finding to fill a row is worse than an honest NO.
+
+**The rule that keeps the answer true:** a gate ships with a decoy test that has been seen to fail.
+`scripts/decoy_coverage_gate.py` refuses a new gate that has neither one nor a named exemption
+carrying its row — and it convicted *itself* the moment it was registered, which is how it got one.
+The 20 gates not yet covered are listed by name (R-426), so the debt is visible and shrinks.
+
+## A guard aimed at the wrong repository trains everyone to bypass it (2026-09-01, R-404 / R-417)
+
+**The ruling was neither option as framed.** The question on the table was whether a documents-only
+push should be subject to the golden-currency gate, and both answers offered — *narrow the gate*, or
+*leave it and write waivers* — argued about the gate. **The gate was never the problem.**
+
+The diagnosis, measured from live source rather than reasoned: `golden_currency_gate.py` **never
+looks at the push**. It compares the controller's newest CHANGELOG heading against this repo's bake
+evidence and returns the same verdict whatever you are pushing — correct for a standing invariant,
+wrong as a push gate. And `controller_gates.py` had **no golden-currency entry at all**. So the
+repository where a release actually happens never checked, while the repository that cannot create
+the debt enforced it on every push. **18 of the last 24 pushes here touched no code** — measured, and
+the classifier built for this agrees exactly — most of them by construction, because the controller's
+code lives in one repo and its register, architecture and status live in this one. Worse: **six of
+those eighteen were bake records**, so the push that pays the debt is itself documents-only and the
+gate was blocking its own cure. `--no-verify` had been reached for thirteen times, each with a
+recorded reason, which is what a correctly-bypassed guard produces.
+
+**The ruling: block the push that can create the debt, notify the push that cannot.** The gate's
+logic, exit codes and wording are byte-identical; only the consequence changed, for one gate, on one
+kind of push, with a loud ADVISORY block so nothing goes quiet. A notice now fires in the controller
+repo at the moment a release is committed — advisory in every case, because at that moment the golden
+legitimately cannot exist yet.
+
+**Why not the waiver the gate's own docstring prescribes.** That clause was written for *a release
+nobody wants a golden for*. The case that actually occurred was *a release we did want a golden for,
+on a night the drill runbook forbade baking*. A waiver would have recorded a lie.
+
+**What did NOT change, and must not be presumed:** nothing gates the **vouch**. A baked-but-unvouched
+golden still passes both the gate and the new notice — R-242's remaining half, still open, for the
+unchanged and forced reason that the vouched version exists only in the hub's database.
+
+## Skills cover the PROCESS domain too, from named MIT sources with named exclusions (2026-08-25)
+
+**[RULING] `felhom.eu/skills/` now holds two kinds of skill and the distinction is deliberate.** The
+four originals — `felhom-app-catalog`, `felhom-build-deploy`, `felhom-testing`, `felhom-ui-design` —
+are **product-domain**: what the system is and how to change it. The five added 2026-08-25 —
+`felhom-evidence`, `felhom-diagnosis`, `felhom-plain-language`, `felhom-handoff`,
+`felhom-doc-authoring` — are **process-domain**: how work is judged, diagnosed, written up and handed
+over. The gap they close is that two rules this project had already paid for lived only in
+conversation, so Claude Code never read them.
+
+**The process skills are ADAPTATIONS of two MIT collections (`mattpocock/skills`,
+`backnotprop/pstack`), not copies, and neither repo is installed, vendored or depended on.** Six
+pieces of upstream material were excluded on purpose — most importantly *"stop asking and proceed on
+reversible work"*, which reasons from *code is cheap and revertible*; Felhom's work reaches live hosts
+and one real customer's data, where that premise is false. **The exclusions and their reasons live in
+`skills/SOURCES.md`**, so a session that finds the upstreams sees a decision and not an oversight.
+
+**One rule, one home — this is load-bearing, not tidiness.** A rule that already lives in another
+skill or in `documentation/runbooks/workspace-CLAUDE.md` is POINTED AT by name, never restated: two
+copies drift and the reader cannot tell which is current. So `felhom-diagnosis` sends you to
+`felhom-testing` for the red-proof, and `felhom-evidence` cites standing rules 2 and 3 in one line
+each. **`skills/felhom-doc-authoring/SKILL.md` is where that rule and the 150-line limit are written
+down** — read it before adding or editing any instruction file.
+
+**Validation: `python3 scripts/check_skills.py`.** `install_skills.py` globs `skills/*/SKILL.md` and
+never reads the file, so a skill missing its `description` installs perfectly and then silently never
+loads. The glob is the registry — **a new skill directory needs no registration, and no manifest or
+index may be added.** What the checker CANNOT see is whether the model actually reaches a skill when
+it should; that is behavioural, decided by the `description` wording, and it is checked by the
+operator typing a probe phrase, never claimed from a green run.
+
+## Cooldown GRAIN is allow-listed, never inferred from the payload (2026-08-23, R-389)
+
+**[RULING] Per-app cooldown is a NAMED REGISTER (`perAppCooldownEvents`), not a rule of the form "if
+the details carry a `stack_name`, split per app".** The backup family's cooldown is coarse **on
+purpose** — R-97a and R-182 exist so one full disk sends one digest rather than one mail per app.
+
+**[FACT] The payload-shape rule would have been wrong, and provably so.** `crossdrive_failed` is
+severity `error`, reaches the operator leg, and carries `stack_name` through **`CrossDriveDetails`**,
+a different struct from `AppDetails`. Anything keying off the field would have split it silently.
+**That is why `cooldownStackSuffix` takes the EVENT TYPE as well as the details** — an asymmetry with
+`cooldownTierSuffix`/`cooldownRunSuffix`, and the asymmetry IS the safety property: `tier` and
+`run_id` appear only on types that want that grain; `stack_name` does not have that property.
+
+**[RULING] `app_start_failed` gets per-app because it has NO DIGEST.** There is no `apps_down_run`
+summarising a scan the way `backup_run_failures` summarises a run, so per-app is the only grain that
+does not lose alarms. **The hour did not change** — the grain was the complaint, not the length.
+
+**[FENCE] The fenced act is adding an entry to `perAppCooldownEvents` for a type whose family has a
+digest or a deliberately coarse cooldown.** Reading it is fine.
+
+**[MEASURED] Burst volume, so it is a number and not an impression:** three apps in one scan →
+**3 attempted, 3 sent, 0 suppressed**. Reference box has 8 deployed apps, so a total outage is 8
+mails. It scales linearly and has no ceiling; the reopening condition is a box big enough that a
+total outage is unreadable, and the answer there is a digest, not a wider cooldown.
+
+## A finding recorded only in REPORT.md has a lifetime of ONE SESSION (2026-08-23, R-389 / gate 11)
+
+**[FACT] This cost a day.** The cooldown-grain defect was measured live on 2026-08-23, written under
+`## Observations` in `REPORT.md`, and written **nowhere else**. `REPORT.md` is overwritten every
+session by this project's own convention. It had no register row and had to be re-derived the next
+day. Same shape as R-341.
+
+**[FACT] The instruction invited it.** `PROMPT-TEMPLATE.md` §15 asked for observations *"documented,
+NOT acted on"*, and "documented" was satisfied by the paragraph. **The template was the defect**, and
+it was corrected in the same session that built the mechanism.
+
+**[MECHANISM] Gate 11 (`scripts/observations_gate.py`).** Every numbered item in a `REPORT.md`
+observations section must carry `FILED: R-NNN` (which must resolve) or `NOT-A-FINDING: <reason>`. It
+REFUSES; it does not warn. It PASSES quietly when there is no observations section, deliberately — a
+gate that taxes every push gets disabled within a week.
+
+**[RULING, and it contradicts the task that commissioned it] A bare mention of an R-number does NOT
+satisfy the gate.** The specification said an item may "cite an R-NNN that resolves" — **that rule
+would have passed the very item the gate was built to catch**, because the lost item cited `R-182` as
+an *analogy*. No parser can tell citation-as-precedent from citation-as-filing by reading prose. The
+marker is explicit for that reason, and the discrepancy is recorded in the gate's docstring rather
+than quietly resolved.
+
+**[GOTCHA] Registered in three runners, not four.** `catalog_gates.py` has no shared-gate mechanism —
+`run_gate` joins against its own `scripts/` and the loop appends `--all` to every gate — so
+registering there needs its contract widened. Filed as **R-391** rather than left as a sentence,
+which is this session's whole lesson.
+
+## The severity a controller sends is the HUB's vocabulary, and getting it wrong deletes the alert (2026-08-23, R-329 / R-387)
+
+**[RULING] The set is exactly `{info, warning, error, critical}`.** The hub **coerces anything else to
+`info` at ingest**, and `severityNotifies` drops `info` **before both** delivery legs. So a severity
+outside the set means: stored, `200` returned, dashboard shows it, **e-mailed to nobody**.
+
+**It shipped twice** — `DiskAlertKind.Severity` until controller v0.215.0, `app_start_failed` until
+v0.223.0. Measured on the live hub DB: **91 `app_start_failed` events stored all-time, ZERO
+`notification_log` rows** before 2026-08-23.
+
+**[MECHANISM, because a comment already recorded this lesson and it happened again]** An AST walk over
+the whole controller pins every emitted severity. **grep cannot do this job** — `"warn"` is a
+legitimate *healthcheck status* in `internal/monitor` and `internal/selftest`; the 2026-08-23 sweep hit
+nine such strings and exactly one defect. The walk cannot follow a variable, so the six call sites that
+pass one are **registered by name with the values each can take**; a new dynamic site fails the test.
+**An unlisted limit is not a limit, it is a hole.**
+
+**[RULING] The hub's coercion STAYS and now SPEAKS (hub v0.107.0).** A rejected event is a *lost*
+event, and losing an alarm is worse than mis-routing one — that is why it was a coercion. The fix is
+that it logs `WARN` naming customer, type and value. **The guard that should have caught this class sat
+downstream of the rewrite and was structurally blind to it** — note the asymmetry it lived beside: an
+unknown event *type* 400s loudly, an unknown *severity* was silent.
+
+**[RULING] `dispatcher.go`'s `unrecognized severity` branch is KEPT, on evidence.** `cmd/hub/main.go`
+wires `ProcessEvent` **directly** as the `monitor.EventNotifyFunc` for three checkers that never pass
+the ingest handler. For those it is the only severity guard there is.
+
+**[RULING] `app_start_failed`: operator always, customer OFF by default.** `processOperator` consults
+only `operatorOn`, the address and a 1-hour cooldown — **never** customer preferences — so one word
+fixed the operator leg and left the customer leg where the ruling wanted it. It is deliberately **not**
+in `operatorOnlyEvents`: that would make the new toggle visible, flickable and structurally incapable
+of delivering.
+
+**[GOTCHA, now load-bearing] The operator cooldown key carries no app identifier**
+(`customerID:eventType`), so **only the first app-down per hour e-mails the operator**; the rest are
+logged `suppressed`. Harmless while the event was undeliverable. Not any more. R-182's shape, filed.
+
+## "The customer stopped this" is a RECORD, never an inference (2026-08-23, R-386)
+
+**[RULING] Ask `DesiredState`, do not read the container state.** `aggregateState` folds `StateExited`
+into the stopped counter, so an all-down stack returns `StateStopped` whatever killed it — an
+out-of-band stop and a customer's Stop are byte-identical on the Docker side. Measured: `privatebin`
+stopped out of band, nine scans, **zero events, zero banner**, while a comment claimed it "still
+alerts".
+
+**[RULING] The tri-state, and the third value is the whole safety property.** `Stopped` → no alarm.
+`Running` → **alarm**. **Absent → UNKNOWN, keep the old behaviour, AND announce it.** Reading absent as
+"nobody asked" would, on the first cycle after upgrade, e-mail about every app any owner ever
+deliberately stopped — fleet-wide, from a field that predates the intent being asked of it. **The
+backfill cannot help: it seeds `Running` only from an observed-UP reading**, so anything stopped at
+upgrade time stays unknown — exactly the ambiguous population.
+
+**[MECHANISM] `AppRunState.IntentUnknown` + an INFO line naming the apps**, on the heartbeat cadence.
+An operator must be able to ask *"how many apps am I blind to?"* and get a number. **A rule without a
+mechanism is a wish.** Measured on `demo-hp`: **0 of 8** deployed apps had an absent intent.
+
+**[FENCE] Adding a `DesiredState` WRITER is the fenced act; reading it anywhere is fine.** Twelve of
+`StopStack`'s fourteen callers are machines, so recording intent in the primitive would make a nightly
+backup indistinguishable from the customer pressing Stop.
+
+**[FENCE] `failedRestart` must still lift a `Stopped` intent** — the quiesce loop stops stacks by the
+same path a customer does, and one it stopped and could not restart must alarm whatever the intent
+says. Removing that term re-opens F-CRIT-1.
+
+## Two settings toggles each governed two alarms, and the labels named one (2026-08-23)
+
+„Lemez figyelmeztetés (90%+)" also wrote `disk_critical` — the drive-is-**failing** alarm. Split into
+four honest toggles; **12 → 15**. **[RULING] The migration, not the split, was the risk:** a save whose
+event **set** is unchanged now stores the **existing slice verbatim**, so byte-identity is by
+construction. Without that guard the defaults case reorders — the red-proof caught it. Legacy compound
+form names are still read, so a stale browser tab cannot drop a key.
+
+## Customer notification model — DIRECTION, recorded and deliberately NOT implemented (2026-08-23, R-388)
+
+The operator's framing, verbatim: *"A customer should be notified only about things they can act on or
+are responsible for… **A failed backup is our incident, not theirs.**… The subscription should feel
+like being looked after, not like being on call."* Full entry at
+`documentation/architecture/08-alarm-ladder.md` §8, marked **not current behaviour**. The settings page
+grew 12 → 15 toggles in one session and grows by one per detector — that growth is the argument.
+**Nothing in this session implements it.**
+
+## App data placement is a DECISION, and it had never been written down as one (2026-08-22, R-376)
+
+**Recorded here on 2026-08-22 to give an existing decision a home. It is NOT new, and this entry is
+not its date** — the choice is older and its original date is not on record. That is itself the
+finding (R-376).
+
+**The decision.** App data is placed **per volume, not per app**. `.felhom.yml` classes each volume
+**hot** — database, config, cache — which goes to fast storage inside the guest and is **enforced**;
+or **bulk** — media and files — which may live on slow attached storage. A photo app's database stays
+on the SSD while its blobs go to the USB drive. Recorded shape:
+`architecture/01-topology-and-trust.md:150-152`, now marked **[DESIGN]**.
+
+**What follows from it, and is a consequence rather than a separate choice:** 40 of the 53 catalogue
+templates declare no configurable data path, because they are all-hot apps. The 13 that do are the
+media and library apps. Stated as **[FACT]** at `07-backup-architecture.md:296-299`.
+
+**What was rejected, so the same proposal does not return.** Moving named-volume (all-hot) app data
+onto the default data drive was proposed in `SPEC-app-data-placement-2026-08-21.md` §5 and is
+**rejected**: it would move hot data onto storage this design classes as possibly-slow, and would put
+it outside the guest vzdump that currently protects it (`01-topology-and-trust.md:154-156`). The spec
+carries the correction inline.
+
+**Why this entry exists at all.** The decision was real, implemented and load-bearing, and lived in a
+single unmarked bullet. Between 19 and 22 August it was called a defect in four places (R-370),
+because a reader met a marked `[FACT]` beside an unmarked choice. **A decision nobody wrote down as a
+decision is one somebody will eventually report as a bug.**
+
+## Read the architecture folder BEFORE calling something a defect (2026-08-22, R-370 / R-369)
+
+**Between 19 and 22 August the reviewing side called a documented architectural decision a defect, in
+four places.** The decision is in `architecture/01-topology-and-trust.md:150-152`: `.felhom.yml`
+classes each volume **hot** (DB/config/cache → fast storage, **enforced**) or **bulk** (media/files →
+may be slow). The 40 catalogue templates with no `HDD_PATH` are all-hot apps — their data is app
+internals and belongs inside the guest, on its own volume so it cannot fill the OS
+(`felhom-agent/configs/build-golden.sh:29-40`). The 13 with a path are the bulk apps. **There is no
+choice being denied**, and the deploy page has been telling the customer exactly this all along:
+*„A kiválasztott meghajtón az alkalmazás fájljai (média, dokumentumok) tárolódnak. Az adatbázis a
+gyors belső SSD-n fut"* (`deploy.html:624-625`).
+
+**Why it happened, mechanically: the register and live source were read; `documentation/architecture/`
+was not.** Nothing in `PROMPT-TEMPLATE.md` §4 required naming the architecture document for the area
+being touched — item 4 named only the controller module map, and the S-1 rule governs *updating* a
+design doc at the end, not *reading* one at the start. **Fixed in the same session:** §4 now carries
+the file→area map, the ordering *architecture = reasoning, register = work, source = truth*, and the
+test **"is what I am about to call a defect something we chose?"**
+
+**Corrected in place, not rewritten** — `SPEC-app-data-placement-2026-08-21.md` and R-352 carry
+`[CORRECTED 2026-08-22]` blocks that say what they got wrong; a document that quietly changes its mind
+teaches nobody.
+
+**And the sibling failure, R-369: there are two registers.** `OPEN-ITEMS.md` calls itself the single
+source of truth; `ROADMAP.md` also holds open work. 72 `R-` ids live only in ROADMAP, 29 of them not
+marked done. **R-107 — the off-site restore never unpacking its own volume tars — was filed there on
+2026-07-28, one day after OPEN-ITEMS was created, and never entered the register. It was rediscovered
+from scratch 25 days later by the 2026-08-21 drill and shipped as R-354.** The template now says
+plainly that a ROADMAP row alone does not satisfy the filing rule.
+
+## Box REACHABILITY is a separate signal from box FILL — and the cadence difference is deliberate (2026-08-18, R-339, hub v0.106.0)
+
+Both off-site checkers now carry two independent signals, and conflating them is the mistake to avoid:
+
+- **FILL** — how full is the store. Escalation-only (one emit on a band rise), and **a degraded or
+  missing reading drives NO band transition**, because missing ≠ 0%. That rule is unchanged by
+  v0.106.0 and must stay unchanged: it is what stops a dead endpoint from reading as an empty one.
+- **REACHABILITY** — can the hub see the store at all. Counted in consecutive failed fetch windows,
+  emitted past a threshold (default 3 ≈ 30–45 min) with a paired all-clear.
+
+**Why reachability REPEATS rather than escalating once.** `emitFill`/`emitOversub` fire once on a band
+rise and stay silent while the condition persists, which is right for a capacity trend. Applied to
+reachability it would produce exactly ONE mail at roughly minute 30 of a nine-hour outage — and one
+mail is missable, which is the whole failure being fixed. So the unreachable event fires on every
+failed window past the threshold and relies on the dispatcher's 1-hour per-type operator cooldown to
+become an hourly "still blind" heartbeat. **If you find yourself "fixing" this back to the band shape,
+this paragraph is why not.** The cost is a `suppressed` notification row every ~15 min during an
+outage — honest bookkeeping.
+
+**Two boundaries worth holding in mind.** `ErrUsageUnsupported` is *not* blindness — an ep0 on an old
+tenantsync answers "no such op", which means we reached it; the counter is not advanced, or the alert
+would fire for days on a healthy pre-update box. And the reachability read rides ep0's **local API
+daemon**, not the HTTPS proxy on 8007 — so it would have shown green throughout the 2026-08-18 outage,
+which is R-340 and is the honest limit of what this watches.
+
+## The managed floor now tracks the vouched golden — and that is rule 2 ARRIVING, not an exception (2026-08-18, R-343)
+
+Since 2026-08-18 12:36:58Z the global managed controller floor
+(`hub_settings.min_controller_version`) reads **0.216.0**, equal to the vouched golden. Read it from
+the store (`GetGlobalMinControllerVersion`, `hub/internal/store/store.go:1751`), never from the form.
+
+**Do not read the preceding gap as drift.** `publish-train-rules.md` rule 1 is *manifest before
+floor* and rule 2 requires the floor field saved **LAST, in a separate save**, because the DB row
+overrides the env floor and acts on the next report cycle. The floor therefore sits behind the newest
+controller **by design** for as long as it takes to bake and vouch a golden — and it is raised
+afterwards. Floor-equals-golden is the state that ordering is meant to arrive at; a session finding
+the floor behind should check whether a vouch is outstanding before calling it a defect.
+
+**The raise is not free, and this is the part worth remembering.** Rule 2's "acts immediately" is
+literal: nine seconds after the save, `demo-felhom` auto-updated 0.214.0 → 0.216.0
+(`controller_updated` 12:37:07Z, `controller_started` 12:37:12Z, no error events). So a floor raise is
+a fleet action, not bookkeeping — plan it as one. `ResolveManagedFloor`
+(`hub/internal/store/store.go:2068`) is what makes it safe: it holds the floor entirely when it
+exceeds the golden (R-216), and per-box when that box's agent is below the manifest's `MinAgent`.
+
+## A name must differ from its neighbours on a stem, not on a noun (2026-08-13, R-323)
+
+The third near-homograph is renamed: the five-word phrase that proves an account owns the box being
+bound is „**Tulajdonosi jelmondat**". It was „Visszaállító jelszó" — one word from the „Visszaállító
+kód" retired days earlier, and false besides: **the phrase restores nothing.**
+
+**The rule this instance yields, and it generalises past this secret.** Both obvious replacements were
+rejected, and the reasons are the transferable part:
+
+- **Do not name a secret after the ACT it is used in, when another secret on the same screen is named
+  after the same act.** The other factor on that page is the „**Párosító kód**". „Összekötési jelszó"
+  would have left the two things a customer types in one sitting separated only by *kód*-versus-
+  *jelszó* — **structurally the very trap being removed**. A name that matches the page's verb feels
+  right and is the wrong axis.
+- **Do not name a secret after a THING that already has a password.** „Fiókjelszó" collides with the
+  dashboard login, i.e. trades one homograph for a worse one.
+- **Separate on the STEM first, the noun second.** Beállító / Helyreállítási / Párosító / **Tulajdonosi**
+  — four distinct stems; *kód* / *jelmondat* is the second axis, not the first. A pair distinguished
+  only by its noun is what failed twice.
+
+**Naming is not function, and the pin says so** (`TestSelfBindPassphrase_StillAcceptedAfterTheRename`
+drives the real handler with human-messy spacing). **Nothing printed was stranded** — no customer
+document names the phrase; it is delivered out-of-band, so the description in the hint sentence is
+what identifies it, which is why that sentence was kept and extended rather than trimmed.
+
+## A guard is worth what its positive control is worth (2026-08-13, R-324)
+
+The hub's customer copy came under a guard for the first time — every customer e-mail and both binding
+pages, the sentences a customer reads *before* they have seen any box screen. Nothing had ever looked
+at them, in either repo.
+
+**The part worth carrying: the selftest found a defect in the guard itself on its first run.** The
+plant→convict→remove→pass control convicted its own step-3 case (a phrase inside a comment) because
+the synthetic source was named `<selftest>` and comment-stripping keys off the `.go` extension. **A
+guard that had shipped without a control would have been quietly over-broad**, and the first person to
+write an honest explanatory comment would have been convicted by it.
+
+**And on sharing a word list across two repos:** the vocabulary lives once, in `scripts/`, the same
+home both repos already consume gates from. The consumer that could not be edited that evening is
+**drift-checked rather than duplicated** — the gate reads the other gate's literal and fails on
+divergence. That is a scaffold with a register row (R-325) to remove it, not a design; **two copies of
+a word list is the R-299 defect waiting to happen**, and a drift check is the cheapest way to refuse
+the copy without making a cross-repo edit at the wrong moment.
+
+## Suppress an alarm on the machine's own declaration, never on an inference — and check for the second door (2026-08-13, R-321)
+
+A box whose reporting is deliberately switched off announces it (`health.status = "disabled"`) and
+then goes quiet by design. The hub stored that, rendered it, and **alarmed on it anyway**, because the
+staleness verdict was computed from report AGE alone.
+
+**Three things worth carrying:**
+
+1. **The discriminator must be the box's own last word.** That is what made this a suppression rather
+   than a guess — and the standing rule is right that suppressing on a guess is worse than the false
+   alarm it removes.
+2. **RECORD the state; do not delete it.** The `blocked` precedent deletes, and `GetState` then
+   returns `""` — which is not `"down"`, so **`CheckBackupDeadlines` would have gone on alarming from
+   a second function.** One fix, two doors; R-195's shape returning through the one nobody looked at.
+   *Ask of any suppression: which OTHER checker reads this state, and what does it see now?*
+3. **A clock must restart at the event that ends the suppression**, not at the last observation before
+   it began. Timing from the pre-disable report would fire an instant stale/down for a quiet period we
+   requested. Re-entering the new-customer branch gives a first observation instead of a recovery
+   event.
+
+**The limit is stated in the code, not hidden:** a box re-enabled that then fails to report keeps
+being suppressed, because the hub's view changes only when a report arrives. **That is why the state
+is made visible** — an operator who re-enabled a box and still sees `disabled` is being told it has
+not come back.
+
+**And a test lesson:** red-proof 2 revealed that scenario A passed on its state assertion alone even
+with the suppression deleted, because it seeded the customer *already* disabled and the new-customer
+branch swallows the first observation. **A test that cannot see the alarm it exists to prevent is not
+a test** — it now observes the machine healthy first.
+
+## A number everyone repeats is a claim, and claims get checked (2026-08-13, R-326)
+
+"The nine grey claims" was repeated across sessions and **exists nowhere**. A session asked to report
+on them could not determine which nine and declined to guess; that refusal was correct and is the
+finding.
+
+**Nine is real and answers a different question: it is the count of claims carrying
+`verdict: downgraded`** — the ones the 2026-08-09 pass *lowered*. The count of unproven claims is
+**32 of 55** (`walked` 23, `partial` 14, `built` 14, `missing` 4), and of those 32 only **6** cite an
+evidence document.
+
+`scripts/unproven.py` makes it a command, wired into the end-of-session checklist. **The generalisable
+part: a picture built for a person to read is not a picture anyone can check.** The dataset carried the
+statuses all along; what was missing was one command that answers the question the operator actually
+asked. Its first run found a stale claim (R-327) — which is the argument for having built it.
+
+## A fact the boxes send and the hub cannot read is a future false green — and one now has a reader (2026-08-13, R-319)
+
+**The first of R-264's twenty-one unconsumed facts is read.** The agent emitted `guest_net` on every
+heartbeat for **twenty-three days** (agent v0.92.0, R-54, 2026-07-21) while the string occurred
+**nowhere** in `felhom.eu/hub/` — stored as raw text in `report_json`, reaching no check, no alarm and
+no screen. Hub v0.104.0 models it: `parseGuestNet`/`guestNet` in `web/hosts.go`, rendered as the
+host-detail **Guest network** card.
+
+**The rule this instance teaches, and it generalises past guest networking:**
+
+- **Read the fact that carries the RISK, not the fact that is easiest to render.** Here that is
+  `heals_last_hour`, not `state`. A guest the watchdog keeps repairing is healthy at every instant
+  anyone looks and is nevertheless failing — rendering the state alone gives it a green tick, which is
+  the failed-disk-drawn-as-a-healthy-empty-disk shape wearing different clothes.
+- **Decode the field that decides the question, not five of the eight.** `heal_succeeded` was added
+  mid-build for exactly this: six FAILED repairs is a guest that is down, six successful ones is a
+  nuisance, and the count alone cannot tell them apart. **R-260 is the standing warning** — a hub
+  decoder three fields short of the agent dropped the one its checker existed to answer.
+- **Three absences, three sentences.** Agent too old / capable agent silent / guest state not asserted.
+  All render unknown; conflating them is how an operator starts ignoring a card. The state switch is an
+  **allow-list**, so adding a state to the agent can never silently paint it green here.
+- **REMOVING an allowlist entry is what proves a reader is wired.** An allowlisted tag is *skipped* by
+  `wire_contract_gate.py`. Re-labelling the eight `guest_net` entries would have left the new reader's
+  own fields unchecked while the gate reported coverage. Deleting them moved checked tags **182 → 190**
+  and skipped **88 → 80** — the positive control that the wiring is real, independent of any test.
+- **A card is not an alarm, and building the card first is deliberate.** No email was added: the
+  incident behind this (a killed `dhclient`, tunnel down 1 h 15 m, nobody told) was a **visibility**
+  failure, and with zero repairs ever recorded on either demo box any alarm threshold would be invented.
+  **The visible count is what will supply the threshold.**
+
+**Where the twenty stand** (R-264, counts measured from the allowlist rather than estimated):
+**8 read · 5 deliberately not consumed · 1 redundant · 6 still owed a reader.** The gate grew a **third**
+entry kind — `not consumed, deliberately` — because an undecided fact and a decided one must not read
+alike, and *"arguably owed"* had been carried for five days as though it were a decision.
+
+**Two findings came out of deciding the last one rather than from building anything:**
+
+- **R-321** — `reporting_disabled` is *redundant* (`health.status = "disabled"` travels beside it, is
+  decoded, and IS rendered), **but `StalenessChecker.Check` is age-only** (`monitor/staleness.go:88+`,
+  sole skip `IsCustomerBlocked`), so a deliberately-silent box still alarms `node_stale` then
+  `node_down`. **Decoding the flag would have felt like progress and left the alarm firing** — the fix
+  belongs in the checker, which already holds the status it needs.
+- **R-322** — `retrieval_promise_gate.py` has **never scanned the hub**, which composes every customer
+  e-mail, i.e. the copy read *before* any box screen. A hand scan with its own four stems returns zero,
+  so it is a scope gap rather than a live defect — recorded before someone writes the first hub-side
+  retrieval promise assuming the guard has them covered.
+
+## One secret in two situations keeps its NAME and changes its SENTENCE — and the mail must name the page the machine shows (2026-08-13, R-295 hub half)
+
+The box side shipped 2026-08-10; the hub half was dropped twice and was the last place „Visszaállító
+kód" survived — in the **mails**, the one surface a customer reads *before* they see any screen. It is
+now „**Beállító kód**" everywhere; the ten-word escrow code stays „**Helyreállítási kód**"; no
+dashboard-code mail names both.
+
+**The mechanism worth carrying: the mail names a PAGE, and which page depends on state only the hub
+knows.** `ReissueForReenroll` sent the *reset* mail, directing the customer to „Elfelejtett jelszó" —
+but a rebuilt box has no password, so the controller computes `reset := s.authEnabled()` → false
+(`felhom-controller/controller/internal/web/claim.go:279`), renders „**A szerver beállítása**", and
+serves **no login page at all**. The named route was not on their screen. **The two situations are
+distinguishable only at the hub, because the hub chose which call site fired** — so the fix is a new
+`EmailKind` (`reenroll`), not a reworded shared template. A `default` branch falls back to the
+first-setup mail, which is the safe direction and is pinned so a future reader knows it was chosen.
+
+**The re-enrol mail deliberately says nothing about apps or backups.** A clean-slate reinstall is
+precisely where that reassurance could be false; `TestFormatClaimEmail_ReenrollPromisesNothingAboutTheData`
+guards the CLAIM rather than one phrasing of it.
+
+**Naming is not function, and the pin says so:** `TestReenrollSplit_ChangesTheMailNotTheSecret` — the
+generation still advances, the stored bcrypt hash still verifies the emailed code, no plaintext is
+persisted. Box-side companion: the controller's `TestResetCode_StillAcceptedOnTheSetupPage`.
+
+## Evidence dies in the INTERMEDIATE revert, not the final one (2026-08-13, R-320)
+
+Twice in three days, on the same box at the same point, a phase's logs were destroyed by a revert to
+`virgin` *between* phases (drill 2026-08-12 Phase A→B; R-316 2026-08-13 Part 1→2). Both times the
+golden-bake runbook's existing *"scp the log OUT first"* was applied to the **final** teardown and not
+the middle one. Both times the conclusions survived on luck.
+
+**Standing rule 5** now: evidence comes off at the end of the phase that produced it, before any revert
+— **the pull is the LAST ACT OF THE PHASE**, not a step to remember later. Four homes:
+`workspace-CLAUDE.md`, `runbooks/target-selection.md`, `RUNBOOK-rehearsal-v3.md`, `PROMPT-TEMPLATE.md`
+report item 8. **And the already-gone case is documented rather than improvised:** say so plainly and
+reproduce the finding independently.
+
+**A corollary this session hit immediately:** the second incident was recorded in `REPORT.md`, which
+every session overwrites — writing tonight's report would have **destroyed the record of a destroyed
+record**. It was preserved to `audits/REPORT-r316-installer-v1.28.0-2026-08-13.md` first. *A durable
+citation may never point at a file whose contract is to be overwritten.*

+# REPORT — R-344: the agent's leaked PBS connections, fixed and proven on both boxes (2026-08-20)
+
+**Outcome: the fix works, measured three independent ways; ep0 is back to its baseline of 17 file
+descriptors from 415; and 0.130.0 is now published and vouched.** Both demo boxes run the **byte-exact
+published artifact**. R-347 is CLOSED. Two new findings came out of the release itself — **R-349**
+(the fleet was briefly running a different binary under the same version name) and **R-350** (I printed
+the hub password into the transcript; rotation is your call).
+
+## 1. Confirmed baselines
+
+| repo | in | out |
+|---|---|---|
+| `felhom-agent` | `f17ed11` — v0.129.0 | **`ede49b6`** — 0.130.0, UNRELEASED |
+| `felhom.eu` | `9299f85` | docs + register only |
+
+Both clean and equal to `origin/main` before each build. Agent version in: 0.129.0 on both boxes.
+Out: **0.130.0 on both**, confirmed from the hub, not from the boxes' own `--version`.
+
+## 2. The diff
+
+| file | symbol | change |
+|---|---|---|
+| `internal/httpx/transport.go` | **new package** | `DefaultIdleConnTimeout = 90s`; `NewTransport(tlsCfg, idle)` — fresh transport per call, `<= 0` means **use the default, never "no timeout"** |
+| `internal/httpx/transport_test.go` | new | zero/negative → default; the constant is read off `http.DefaultTransport`; freshness; TLS config preserved |
+| `internal/pbs/client.go` | `Config`, `NewClient` | `IdleConnTimeout` field (tests only); transport via `httpx` |
+| `internal/pbs/client_leak_test.go` | new | Scenarios A/C + the production-default pin |
+| `internal/hub/client.go` | `NewClient` | via `httpx` — **consistency only, did not contribute to the leak** |
+| `internal/proxmox/client.go` | `NewClient` | same |
+| `cmd/felhom-agent/main.go` | `version` | 0.92.1 → 0.130.0 (ldflags default) |
+| `REUSE.md`, `CHANGELOG.md` | — | `httpx.NewTransport` entry; the release note |
+
+Commit `ede49b6` on `main`. `grep '&http.Transport{'` now matches only `httpx` itself.
+
+**A check made before trusting the fix:** `doBody` already reads the body to completion and closes it,
+so the connection genuinely reaches the idle pool. Had it not, the idle timeout would have been the
+wrong fix entirely.
+
+## 3. Tests and the red-proofs
+
+`go build ./... && go vet ./... && go test ./...` → **30 packages, 0 failures.**
+`python3 scripts/agent_gates.py` → **all 4 gates OK.**
+
+The leak test counts connections **server-side** and models what `pbsTargetsFromPVE` does — build a
+client, use it once, drop it. It deliberately does **not** assert `err == nil` or that a field holds a
+value; both were true of the leaking code (the R-224 lesson).
+
+| red-proof | mutation | seen failing with |
+|---|---|---|
+| 1 — the fix | remove `IdleConnTimeout` | *"abandoned pbs.Clients: after 5s the server still holds 5 open connection(s), want 0 (5 dialled in total)"* — the count is in the message, so it cannot be a timeout with another cause |
+| 2 — the worse fix | `DisableKeepAlives: true` | **the leak test PASSES.** Caught only by `TestPBSClient_KeepAliveStillReuses`: *"3 sequential requests over 3 connection(s), want 1"* |
+
+**Red-proof 2 is the load-bearing one: Scenario A alone would have accepted a fix that made the problem
+worse** — no leak, at the price of a fresh dial for every one of ~40,000 daily requests. Both mutations
+reverted, tree re-verified clean.
+
+## 4. §4 quoted, beside the results
+
+> **P1** — *"(i) ep0's fd count falls by ≈194 within seconds … (ii) … ≈194 sockets convert ESTAB →
+> CLOSE-WAIT … (iii) neither — the count barely moves. Then the ownership attribution is wrong and the
+> finding must be withdrawn."*
+> **P2** — *"demo-hp (fixed): ≈ 0 … demo-felhom (control, untouched): ≈ 4 per hour → ≈ 16 over 4 h."*
+> **P3** — *"ep0's overall leak rate should fall from ≈ 200/day to ≈ 100/day while one box is fixed, and
+> to ≈ 0/day after Part 5."*
+
+## 5. P1 — **outcome (i)**, in one second
+
+| | ep0 fd | ESTAB | demo-felhom | demo-hp | CLOSE-WAIT |
+|---|---|---|---|---|---|
+| T-0 `09:15:46Z` | 415 | 398 | 199 | **199** | 0 |
+| T+1s `09:15:47Z` | **216** | **199** | 199 | **0** | **0** |
+| T+60s `09:16:42Z` | 218 | 201 | 199 | 2 | 0 |
+
+**Outcome (ii) did not occur, so it gets no register row.** Not one socket converted to `CLOSE-WAIT`:
+ep0 reaps on peer FIN correctly. That also means the 543 `CLOSE-WAIT` at the 2026-08-18 wedge has some
+other explanation and is **not** evidence of a second defect on the protected machine — a finding in the
+negative, worth the sixty seconds it cost.
+
+Ownership is now proven a **third** independent way: what dies with the process, agreeing with
+`ss -tnp` and with the access-log user agent. At 133 s uptime the fixed box held **0** connections.
+
+## 6. P2 — divergence
+
+**Window 09:15:47Z → 10:17:52Z = 1.03 h. You closed the ≥4 h window early**, so no daily rate is
+extrapolated and none is needed.
+
+| box | agent | start | end | delta | per hour | predicted |
+|---|---|---|---|---|---|---|
+| `demo-felhom` CONTROL | 0.129.0 | 199 | 203 | **+4** | 3.87 | ≈4 |
+| `demo-hp` FIXED | 0.130.0 | 0 | 0 | **+0** | 0.00 | ≈0 |
+
+**The assumption-free statement.** ep0's access log counts the opportunities: each box made **exactly 4
+`/snapshots` and 4 `/version` calls** in the window.
+
+> **control: 4 cycles → 4 leaks. fixed: 4 cycles → 0 leaks.**
+
+**Positive observable (standing rule 3):** a zero leak is equally consistent with "the agent stopped
+working" — it did not; its four cycles are in ep0's log. The boxes' other traffic is near-identical
+(`libwww-perl` 924 vs 926, `proxmox-backup-client` 898 vs 898), so **the only difference between them
+is the binary**. Poisson alone gives P(0 | λ=4) = **1.8%**, which is suggestive rather than conclusive
+and is not relied on alone.
+
+## 7. P3 — the second box, and the backlog clearing itself
+
+`demo-felhom` upgraded `10:18:56Z` on your word.
+
+| | ep0 fd | ESTAB | CLOSE-WAIT |
+|---|---|---|---|
+| T-0 `10:18:55Z` | 220 | 203 | 0 |
+| **T+2s** | **17** | **0** | 0 |
+| settled 10:30–10:35Z | **17–19** | 0–2 | 0 |
+
+**17 is precisely ep0's `t0` baseline** (fd 17, ESTAB 0, 2026-08-18 09:51:22Z), and it returns to 17
+between poll cycles — the "healthy proxy near 20 fds" the incident document named. Predicted ≈0/day
+residual; **observed the baseline itself.**
+
+**A correction, made within the hour it was written.** My STOP 1 report and the first CHANGELOG draft
+said *"does not clear the 388 descriptors already stuck on ep0 — those persist until that proxy
+restarts."* **Wrong.** They were held on both sides; restarting the agents released every one. **ep0 was
+read-only throughout and its proxy PID never changed (551655).** Corrected in the CHANGELOG, the audit
+document and R-344 rather than quietly edited.
+
+## 8. Fleet sanity
+
+Hub reports **0.130.0 on both** boxes. **No `floor held`** line (0.130.0 > golden MinAgent 0.129.0).
+**No `pbsdr_box_unreachable` / `offsite_box_unreachable`** during any window. Positive observable
+rather than the absent one: the PBS-DR gauge kept refreshing (`3.7% full (3.7 GB of 97.9 GB)`) and host
+reports kept landing from both boxes throughout.
+
+## 9. What is NOT done
+
+- **Not published.** No package, no tag, no manifest or floor field touched, no self-update staged.
+  **A box installed from the current image still ships the leaking agent** — **R-347**, your call.
+- The CHANGELOG heading is `## UNRELEASED — v0.130.0 candidate`. The `release-complete` gate convicted
+  on `## v0.130.0` because there is no tag and no package, and **it was right to**. I did not use
+  `--no-verify`; I made the heading stop claiming a release that has not happened. It flips to
+  `## v0.130.0` in the same commit as the tag.
+- Poll rate unchanged (**R-336**, re-scoped). `pbsTargetsFromPVE` not refactored; no
+  `CloseIdleConnections` added. ep0 not touched.
+- **The 388 descriptors ARE cleared** — see §7. This is the one item the prompt expected to remain
+  outstanding, and it did not.
+
+## 10. Register
+
+- **R-344** — updated with the fix, P1's outcome named, and P2/P3's numbers. **Left OPEN**, because a fix
+  on two boxes by hand is not delivered.
+- **R-336 — re-scoped.** Its new next-step cell, verbatim: *"**NEW ACCEPTANCE CRITERION, since the old
+  one is void:** the fd count is NOT the observable for this row any more — that belongs to R-344 and is
+  already satisfied. Measure the REQUEST RATE at ep0's access log, and state the projected rate at the
+  target customer count."* The row now records explicitly that its old next-step **would have "fixed"
+  nothing while looking like a failed fix**, and re-scopes it to what it is: ~85,000 requests/day to a
+  weekly-write DR endpoint, ≈**25 requests/second at fifty customers** against a CX33.
+- **R-347 (new)** — the delivery gap. Owner: **Viktor decides**, CC executes.
+- **R-348 (new)** — an agent restart blanks the reported backup list for up to ~18 h, and the `Store`
+  comment calls backups *"unaffected"*. **Blinds no alarm** — checked, not assumed: the hub's
+  `backupEvidenceLookback` scans 7 days for exactly this case, and `pbs_snapshots` stayed populated.
+- **No P1(ii) row**, because outcome (ii) did not occur.
+- **R-346** — this run anchored on the measured `t0` (fd 17 at 2026-08-18 09:51:22Z), never on a systemd
+  timestamp, so the 5 h 56 m discrepancy did not touch these numbers.
+
+## 11. CI, by run ID — and the claim ledger
+
+| repo | run | sha | conclusion |
+|---|---|---|---|
+| `felhom-agent` | id **362** / run_number 50 | `ede49b610` — the fix | **success** |
+| `felhom-agent` | id **363** / run_number 51 | `7569f34ae` — the correction | **success** |
+| `felhom.eu` | id **364** / run_number 239 | `57dd62b09` — the write-up | **success** |
+
+No `--no-verify` anywhere. Both repos' pre-push hooks ran their gate entry point and passed;
+`release-complete` passes on v0.129.0, which is the honest state while 0.130.0 is unpublished.
+
+`python3 scripts/unproven.py --summary` — **unchanged: 23 walked, 32 not walked of 55.** No number
+moved, and correctly so: this run proved an engineering fact about our own connection handling, not a
+customer-facing product claim.
+
+**Closing state of ep0**, read one last time after everything:
+
+```
+t=10:40:23Z pid=551655 fd=17 estab=0 ctrl(.2)=0 fix(.3)=0 CLOSE-WAIT=0
+```
+
+`CLOSE-WAIT 0`, `ESTAB` in the low single digits, `fd` at the baseline, proxy PID **551655** — the same
+process that has been running since 2026-08-18 09:51:04, never restarted by this work.
+
+## 11b. The release (R-347, CLOSED)
+
+`bash scripts/release-agent.sh 0.130.0` — the one documented way (R-115): build, tag, publish, and
+**verify by independent download**.
+
+| | |
+|---|---|
+| tag | `v0.130.0` at `7569f34` |
+| sha256 | **`a56a92a7bd68f5b46736eaec4806c3d26c16ccb35118c4ac0e3d8094eaefabc3`** |
+| size | 14,141,158 bytes |
+| reproducible | **yes, checked** — `-trimpath -buildvcs=false` rebuild matches byte for byte |
+
+**Vouched** in the Day-0 artifact manifest: agent 0.129.0 → **0.130.0** + its sha. **Only the agent
+fields changed.**
+
+- **`min_agent` left at 0.129.0** — it states what the **golden controller** needs. Raising it to
+  0.130.0 would have made the hub **HOLD the floor** for every box below 0.130.0, which is the
+  opposite of shipping a fix.
+- **Global floor never touched** (0.216.0). On hub v0.106.0 it is a *separate form with its own
+  action*, so publish-train rule 2's "save the floor last" hazard no longer exists in the shape its
+  incident describes — the rule's reasoning holds, its mechanism has moved.
+- After: no `floor held`, no `*_unreachable`, both boxes reporting 0.130.0, artifact downloading
+  anonymously at the vouched sha.
+
+**No `--no-verify` in the train.** The heading was flipped to `## v0.130.0` only after tag and package
+existed. Flipping first and bypassing would have produced a red CI run and an alarm mail for a release
+that worked — R-168's failure mode.
+
+## 11c. Two findings from the release
+
+**R-349 — the fleet was running a different binary under the same version name.** The proof deploy was
+a hand build; the release builds `-trimpath -buildvcs=false`. Same source, same version string,
+different bytes (`256e0829…` vs `a56a92a7…`). **Self-update could never have corrected it** — the boxes
+already reported 0.130.0, so the vouched version looked installed. Every version check in the system
+compares the *string*. Fixed by installing the **downloaded** artifact on both. The proper fix already
+exists in miniature: `wrapper_sha256` does exactly this drift detection for the PBS wrapper and was
+never extended to the agent's own binary.
+
+**R-350 — I printed the hub password into the transcript.** Confirming the vouch used
+`curl -w '%{redirect_url}'`; the hub answers 303 and curl re-attaches the basic-auth credential to the
+redirect target it prints. **Not in git, not in any committed file** (checked by content), not in the
+evidence directory — it is in the session transcript on DooPlex. Every other call printed only the
+length; this came through curl's own formatting. **Rotation is your call** — I did not do it
+unilaterally, and I can do it file-to-file without printing the new value if you want. The reusable
+half: `%{redirect_url}`, `-v` and `--libcurl` all re-render a basic-auth credential.
+
+## 12. Observations
+
+- **The closure refactor is not worth doing — recommend leaving it.** With the idle timeout restored an
+  abandoned client's connection is gone in 90 s, so the standing population is bounded at about one
+  connection per box instead of growing without limit. Caching clients would add cache-invalidation
+  questions (a storage's fingerprint, token or namespace can change under it) for no observable gain.
+- **Three other `http.Transport` defaults are still missing and were left alone:** `MaxIdleConns`,
+  `TLSHandshakeTimeout` (0 = no limit; `DefaultTransport` uses 10 s) and `ExpectContinueTimeout`. None
+  accumulates, and every client bounds its request with `http.Client.Timeout`. `TLSHandshakeTimeout` is
+  the only one with a plausible failure mode — a stalled handshake over the tunnel, bounded today only
+  by the outer 30 s. Not changed, because widening the diff would have made this measurement
+  unattributable. Worth a look on its own terms; not a defect.
+- **A measurement error of mine, recorded because it nearly cost four hours.** The first P2 sampler
+  reported both per-box columns as 0 while the totals were right: `ss` prints `[::ffff:10.77.0.2]:port`
+  and my pattern expected `10.77.0.2:`. Caught 15 minutes in, because a 0/0 split cannot sum to 199.
+  Fixed, then **one sample proved by hand before committing the window** — which is what should have
+  happened first.

+## 0. Where the brief and the record disagreed — named first
+
+1. **„Off-site (Tier 3) is ON for this customer — its own namespace on ep0."** On the record the ep0 namespace is the
+   **DR tier (PBS)**; restic Tier 3 was **off**, and ticking it provisions a Hetzner Storage Box (money — fenced). Not
+   ticked. The DR tier then could not provision on the new box (R-511). This box had **no off-site tier of any kind**;
+   Phase 4's off-site integrity check and Phase 6's off-site restore onto 9202 were therefore not walked.
+2. **„Expect the hub to issue a fresh claim, or to require its reset flow."** Neither: the hub treated the box as a
+   **re-enrolment** and mailed the *reinstall* setup code („újratelepült … A korábbi jelszavad már nem érvényes").
+3. **„The operator fixed and tested the tunnel."** The route now reaches the box, and still returns 502: it lacks „No
+   TLS Verify" (R-510, with demo-hp's working route as the control).
+4. **Faults F10–F12 were not run** — the brief's own stop rule was met at F9 (R-523).

+# REPORT — the chaos-night fixes: the quiet alarm, the restore record, the recovery-code timing, the slow crash loop
+
+**2026-09-17.** R-549, R-550, R-546, R-539. Per-repo detail: `felhom-controller/REPORT.md` (v0.246.0),
+`felhom-agent/REPORT.md` (v0.132.0). This file covers felhom.eu (hub v0.117.0, the setting, the documents)
+and the whole task. Written as `REPORT-<topic>.md` because `REPORT.md` holds the earlier session's work.
+
+## Claims in the brief that turned out wrong — named first
+
+1. **„Readiness = `escrow.pbs_storage_id` set."** The agent's preflight `ok` covers **five** blocking items;
+   `pbs_storage_id` is the one R-546's box showed. The controller reads the combined `ok`.
+2. **„The backup tiers persist their records atomically."** Checked at `felhom-controller/controller/internal/settings/settings.go:727-752` — **TRUE** (tmp + rename, `.bak` recovery).
+3. **„Ruling A is a config change plus a document line, not code."** WRONG. `hub/internal/web/rollup.go`
+   `controllerStatus` hardcoded 30 m / 1 h while both checkers and `hostStatus` read the config — the
+   dashboard would have turned amber 15 minutes before the alarm could fire. Hub v0.117.0 fixes it.
+4. **„Verify from the log line that the checker runs with 45 m."** No log line printed the threshold.
+   Hub v0.117.0 adds it to both „checker initialized" lines.
+5. **„The failure shows a raw error."** Not in a browser — the page hid its start form behind the
+   checklist. The raw `-storage` stderr came from the chaos-night harness calling the API directly.
+6. **„Emit the event from the agent" / „make the interval configurable for the test."** The agent has no
+   event channel (the hub mints from heartbeat timestamps); and no test interval was needed — five real
+   kills 8 minutes apart reached the production threshold in the session.
+
+## 1. Confirmed baselines (re-verified at start)

+felhom-controller: `0fe315b` (v0.246.0), `29e2acb` (REPORT).
+
+## 4–5. Tests
+Hub: `go build/vet/test ./...` green, 18 packages. Agent: 30 packages. Controller: 28 packages.
+**Red-proofs, each seen failing then passing** — hub: status follows threshold; slow-crashloop movement; operator-only registration; Hungarian subject. Agent: no counter; once-per-24h guard; persistence. Controller: restore record across restart; startup helper; `main()` wiring; restore page card; bar held back; waiting card; start refusal. Two of my own test mistakes corrected and recorded (a body-based fallback check; a `-storage` needle matching a menu id).
+
+## 6. Deployed versions
+Hub **0.117.0** (ArgoCD Synced/Healthy, revision == manifest HEAD, pod ready). Agent **0.132.0** on demo-hp and the N100 (signed jobs, committed). Controller **0.246.0** on demo-hp guest 9201. Proof lines in the evidence directory.
+
+## 7. NOT live-validated
+- R-546's readiness branches (bar held back, waiting card, start refusal) — no Tier-0 box is paused AND agent-connected. **R-551.**
+- The escrow ceremony passing once ready — deliberately **not run**: the hub keeps one escrow per host, and a ceremony on demo-hp would supersede the standing box's escrow.
+- Controller 0.246.0 is on 9201 only; **the fleet floor was not raised** (below).
+
+## 8. Evidence copied off before each teardown
+Yes. B.4(a) log written by the run itself to DooPlex before teardown; teardown logged separately; Part C logs off the box as they ran.
+
+## 9. Teardown — three layers
+- **Machine:** throwaway `homebox` on 9201 removed with data and backups (0 containers, 0 volumes); 10 of 10 standing apps up; password and scripts shredded in the guest.
+- **Host:** nothing provisioned; demo-hp agent config untouched (the `pbs_storage_id` removal was considered and not done).
+- **Hub:** no host or customer record created or deleted; the test events stay as history. Stated effect: 9201's slow crash-loop stays raised until 2026-09-18 09:22Z and cannot mail again before then.
+
+## An error of mine, caught by a gate before it was pushed
+
+Closing R-539, I wrote `open(CLOSED-ITEMS.md,'w').write(open(CLOSED-ITEMS.md).read() + row)`. Python opens
+— and empties — the file for writing **before** it reads it, so the closed register fell from **215 rows to
+1**. The pre-push `instructions` gate refused the push: citations of closed rows (R-549, and R-320 in
+`unprompted-work.md`) suddenly pointed at nothing. **Nothing damaged was pushed.** The file was restored
+from pushed commit `3c1882a` and R-539 appended with read-then-write; the diff against `3c1882a` is exactly
+one added line, and the open register exactly one removed line. The earlier closures (R-546/R-549/R-550)
+used read-then-write and were intact. Lesson kept: never open a file for writing in the same expression
+that reads it.
+
+## A recommendation not followed, with its reason
+The brief's rules say „floor raised to deliver it". **The controller floor was not raised to 0.246.0.** The
+release was validated on one guest; raising a floor above golden 0.245.0 would roll it to Peti's box as
+well, and R-552 (my own gap) was found during validation. One line of evidence is not a fleet decision
+made unattended — the operator's to take, and cheap to take.
+
+## Observations
+1. An interrupted-restore notice for a removed app never clears. **FILED: R-552**
+2. No Tier-0 box can exercise the paused + agent-connected escrow state. **FILED: R-551**
+3. Controller `handler.go` and agent `controllersupervisor_test.go` were not `gofmt`-clean before this task. **NOT-A-FINDING: pre-existing formatting only; reformatting unrelated lines was left out to keep the diffs reviewable.**
+
+## Addendum — the operator's two „yes" answers, carried out (2026-09-17, afternoon)
+
+**1. Controller floor raised to 0.246.0** (declared MinAgent 0.131.0). Hub: `Global controller-version floor
+set to "0.246.0"` and `managed floor SERVED for demo-felhom … from declared`; the N100 ran 0.246.0 within
+seconds (`at/above floor 0.246.0 (we are 0.246.0)`). demo-hp runs 0.246.0 (it has a per-customer override at
+0.243.0). **Peti's box is DOWN on the hub** (last controller 0.115.0) and receives it when it reports.
+Evidence: `audits/evidence-chaos-fixes-2026-09-17/decision1-floor-0246.txt`. The „recommendation not followed"
+above is therefore superseded by the operator's decision.
+
+**2. Agent 0.132.0 vouched — which required a golden.** The first vouch was refused by the hub's R-120 gate
+(`golden 0.245.0 is older than the newest controller the fleet reports (0.246.0)`); nothing was stored. Asked,
+the operator chose to bake. **Golden 0.246.0** baked by RUNBOOK-manual-build §4.1, sha `05b7559d…`, amd64,
+all markers, token leak 0 (control 1), registry 200 before teardown; then vouched together with agent 0.132.0:
+`Artifact manifest set: agent=0.132.0 golden=0.246.0 min_agent="0.131.0" wrapper_sha=true`, read back
+exactly. `golden_currency_gate.py` moved from WAIVED to **OK**. Evidence: `tests/golden-0.246.0-2026-09-17/`.
+
+**Mistakes of mine on the way, none reaching the registry:** the first bake attempt used the **arm64**
+template (my version sort), aborted before anything was built; stopping it, a self-matching `pkill` killed my
+own shell; the second attempt's watcher was killed for low memory and its post-bake steps were done by hand.
+
+**Observation.** 4. `golden_currency_gate.py` reported the newest bake as 0.242.0 although 0.243.0–0.245.0
+were baked and published, because those bakes filed their logs under `audits/` rather than
+`documentation/tests/golden-<ver>-<date>/`. **NOT-A-FINDING: a recording slip in earlier bakes (including
+0.245.0, mine), not a gate defect — the gate reads the place the runbook names; 0.246.0 is filed there and the
+gate reads it.**

+# REPORT — chaos night 2026-09-16/17
+
+Full record: `documentation/audits/DRILL-chaos-night-2026-09-17.md`. Evidence (73+ files):
+`documentation/audits/evidence-chaos-night-2026-09-17/`. Architecture read for the area:
+`documentation/architecture/00-capability-map.md` (the journey and backup rows).
+
+**Interventions: 1** (round 6, a local backup leg that could never fit; the off-site leg then
+succeeded unaided). **Ready for a volunteer: still yes.** **Worst pair: restore + hard reset.**
+
+## Claims in the prompt that turned out wrong — named first
+
+1. „The automatic mail is waiting in the mailbox" — **TRUE**, checked: mail of 18:17:46Z; zero presses.
+2. „The WG hook provisions by itself after an acknowledged delete" — **TRUE**, measured live for the
+   first time: `pbsdr_auto_reissue`, 20:19Z.
+3. „Restore one DB-backed app from off-site onto 9202" — **WRONG for this fixture.** The box is a
+   rebuild; its restic repository is orphaned by design (restic: `wrong password or no key found`,
+   exit 1; product: `orphaned:true, snapshots:0`). Nothing to restore from.
+4. „System disk + one data disk" — **not what ran**: a third 64 G disk was added by me in Phase 0.
+5. Round 7's drawn `update` — **not run**; the catalog's own gates were INCONCLUSIVE. `use` ran, logged.
+6. „An internet cut tests hub unreachability" — **false on this network** (hub resolves to the LAN).
+   Mine; fixed before round 9.
+7. The schedule's clock column was nominal; the twelve rounds ended 00:17Z. Order/apps/accidents unchanged.

+
+## 4–5. Tests
+**N/A — no product code was written** (the brief forbade it). No test count moved.
+`unproven.py --summary`: 35 of 55 not walked — **no number moved**.
+
+## 6. Deployed versions (the box under test)
+golden **0.245.0** (baked and vouched in Phase 0, registry answered 200) · controller 0.245.0 ·
+agent 0.131.0 · hub 0.116.0 · installed from ISO 1.28.0. No deploy to any standing box.
+
+## 7. NOT live-validated
+- Per-app off-site **restore** (orphaned repo by design on a rebuild box).
+- Whole-guest off-site copy **restorability** — listed intact on ep0, not verified (a verify writes state).
+- The **event-drop** path while the hub is unreachable — no event coincided with any of three outages.
+- What a browser renders client-side (endpoint-level validation only; no browser on DooPlex).
+
+## 8. Evidence copied off before each revert
+Yes, per round (R-320). The box's own household log, disk-guard log, loop script and unit files were
+copied off **before** the units were stopped and before the machine was destroyed. Nothing was lost.
+
+## 9. Teardown — three layers
+- **Machine:** VM 336 destroyed with all three disks; `/mnt/hdd_1/images/336` gone.
+- **Host:** `nvme-scratch` 6.78 % → 1.61 %; `local-lvm` unchanged 44.75 %; guests 9201/9202 running;
+  household loop and disk guard stopped and disabled; firewall back to baseline (0 physdev rules).
+- **Hub:** host record `tester-1-022354` **DELETED** through the acknowledged flow at 07:25:13Z
+  (first attempt correctly refused 409 while the host was still live). `drill-r50`, both demo hosts
+  and the `tester-1` customer still 200. Connect mail quoted in `teardown-hub.txt` (token redacted).
+- **ep0:** identical across three readings — 6 snapshots, 16 G. Nothing removed.
+- **Scratch 9202:** nothing was ever placed on it; shown untouched.
+
+## Observations
+- A restore interrupted by the machine stopping leaves no record the household can see. **FILED: R-550**
+- The staleness alarm's budget is two report cycles; one failed push spends it (29 m 59 s measured). **FILED: R-549**
+- A transient full disk between daily sweeps is never mentioned. **FILED: R-547**
+- The whole-guest local tier cannot fit on a small-system-disk box and retries forever. **FILED: R-548**
+- The first-hour guide asks for the recovery code ~17 min before the box can take it. **FILED: R-546**
+- An OOM was detected and named on this box. **NOT-A-FINDING: added as tonight's line on the existing row that owns it (R-528), not a new defect.**
+- The off-site orphan warning is absent from the static HTML of the remote-backup page. **NOT-A-FINDING: the page renders it client-side from the status endpoint (a dedicated orphan card exists).**
+- Eleven faults in my own instruments (mistimed readings, a wrong hub-reachability model, guessed endpoints, a guard that could never pass). **NOT-A-FINDING: harness errors, not product defects; each is recorded with its fix in the evidence.**
+
+**CHANGELOG not updated:** this repo's changelog is per product area (hub/scripts/website) and no
+product area changed tonight — the drill record, register and status note are the record.

+# REPORT — the doorstep: installer 1.27.1, hub 0.113.0, walked again (2026-09-14)
+
+**Supervised task. STOPPED before publishing, as required.** Findings: `documentation/audits/DOORSTEP-walk-1270-2026-09-14.md`.
+A parallel session owns root `REPORT.md`; this is a topic sibling.
+
+## 0. Claims in the brief that turned out wrong — named first
+
+1. **"The ISO is built to install itself with no questions."** Wrong for the public image. `--release`
+   builds carry no answer file by construction (G1); the 1.26.1 manifest says `answer-file: NONE` and
+   `automated-entry: NOT PRESENT`. The README's auto-install text describes the old operator-built images.
+   Nothing "failed to engage".
+2. **"The installer installs itself, in Hungarian" / "no English reaches a volunteer."** Not achievable
+   under the operator's ruling: offered an install-time disk rule, he kept the interactive installer. The
+   Proxmox auto-installer has no local chooser or stop page; its screens stay English. Felhom's own text is
+   Hungarian (G16).
+3. **"Tester 1, fully configured."** It has no e-mail (R-508) and its tunnel gives a new box no routes
+   (R-505).
+4. **"The hub could create the tunnel later" as the only gap in A.1.** `day0-install.md` A.1 also claimed the
+   controller creates the hostnames; it does not (R-506, corrected).
+5. **"Host a Hungarian chooser; else a Hungarian stop."** Not built — follows from 2.
+
+## 1. Baselines (re-verified)

+## 4. The walk
+
+**Interventions: 1** — reaching the dashboard by LAN address (R-505, filed 16:07:59Z before acting).
+Everything else held: install on 3 disks and 1, first-boot console Felhom-only on 1.27.1 with a proven
+reboot, deploy, use, backup-now, removal, **byte-identical restore**, power cut on the same versions, typo
+and lockout. Harness substitutions H1–H5 in the findings doc §4.
+
+## 5. The tunnel, measured — the one thing that stops a volunteer
+
+12 requests from DooPlex through public DNS → **12 × 503**; the box's `cloudflared` logged **12**
+`No ingress rules were defined` in the same window and **0** remote-config updates since connecting. The
+guest's own front door answers the name. **The operator's phone loads the dashboard** — not explained by
+anything the session can see; a second connector reached from another Cloudflare location is the likeliest
+cause and is **not established**. The Pi-hole is excluded for these probes (public DNS, Cloudflare ray ids).
+
+## 6. STOP — for the operator
+
+- **Intervention count: 1.** By the rule set for this task, **do not publish.**
+- **The disk rule:** the installer never picks; it lists every disk with size and model and erases the one
+  you choose; unplug the backup drive; call the operator if unsure. One disk, three disks and nobody at
+  the keyboard were each seen (findings §2).
+- **Gate:** 1.27.1 PASS on every criterion runnable before publish (G1–G10, G13–G16); G11/G12 are
+  publish-time; the graphical entry is proven only to its password screen (R-507).
+- **Ready: NO** — until the `tester-1` tunnel answers from our network, and the record has an e-mail.
+- **What publishing would do, on yes:** upload 1.27.1 + `.sha256` + manifest to the bucket, add the
+  download page to the website, round-trip the checksum over `https://iso.felhom.eu/`, keep 1.26.1 online
+  so rollback is one link change.
+
+## 7. Rows
+
+Opened **R-502 … R-508** (7). Closed **R-497**. Fixed awaiting publish **R-496**; answered awaiting publish
+**R-495**; **R-493** open; **R-494** narrowed to P3. Register table rows **209 → 216**.
+
+## 8. Teardown
+
+Layers 1–2 done (VMs 331/332 destroyed; ≈12.8 GiB back on `nvme-scratch`; both ISOs and `/root/doorstep`
+gone; 9201/9202 untouched). Layer 3: appliance 27 discarded (16:20Z); host `tester-1-8603a2` stale at 16:46:43Z (a true
+`host_stale` operator mail), deleted 16:46:52Z (`host deleted: tester-1-8603a2 (escrow deleted: false)`;
+host page 404, gone from `/hosts`); its ep0 WireGuard peer `10.77.0.5` removed at the 16:49:13Z push
+(0 left, control peer 1). **Customer `tester-1` KEPT** (page 200). **Left on ep0 by the DR tier, read-only
+check 16:51Z:** namespace `tester-1` exists with **2 directories inside — backup data from the test box**,
+plus token `felhom@pbs!tester-1`. Not removed: ep0 is protected, and the only product path (customer
+RESET) would also remove the tunnel. Retained for the operator's ruling.
+The hub's event stream and three operator mails are append-only and stay.
+
+## 9. Observations
+
+- `iso-release-gate.md`'s "both entries" proof depends on a person for the graphical entry today (R-507).
+- The bootstrap harness is run by hand only (R-502); the pairing banner had never been exercised.
+- A closed row still lives in the open register (R-497) until the next compression sweep — the gates accept it.

+# REPORT — DRILL: a stranger's first hour on 0.242.0 (2026-09-14)
+
+**Runbook-style validation. No product code written.** A parallel session owns root `REPORT.md`, so
+this is a topic sibling (`CLAUDE.md`). Findings doc: `documentation/audits/DRILL-fresh-install-0242-2026-09-14.md`;
+every observable: `documentation/audits/evidence-drill-fresh-install-0242-2026-09-14/journal.md`.
+
+## 0. Claims in the brief that turned out wrong, or incomplete — named first
+
+1. **"ep0 is not touched."** Enrolment itself registers a WireGuard peer on ep0 for every box
+   (`wg registered … ip=10.77.0.5/32 … sync=ok`), DR tier on or off. I avoided the part I could (DR
+   tier off, which would have created an ep0 namespace and token); the peer is the product's own act
+   and is removed by the host delete (§5).
+2. **"This run re-proves or narrows the journey row (~L90)."** That row is the **rebuild-and-recover**
+   journey (walk 5). This drill walked the **first hour**, with off-site off. It can neither re-prove
+   nor narrow that row. I added a scope note to it and a **new first-hour row** (PARTIAL).
+3. **"Claim the box with the code."** There are three secrets, not one: the console **Párosító kód**,
+   the operator-held **Tulajdonosi jelmondat** (nothing delivers it — R-497) and the mailed
+   **Beállító kód**. Two of the three arrive by mail, which this harness cannot read.
+4. **The three claims marked "read, not measured"** — measured now: **website** — true, no mention of
+   the installer or `iso.felhom.eu`, and the ISO host has no index; **instructions** — true, none exist
+   (R-493); **golden landing** — the box landed on 0.242.0, the new golden, with no self-update.
+5. **"Newest baked golden 0.236.0; waiver to 2026-09-27; highest R-492; baselines"** — all correct.
+
+## 1. Baselines (re-verified 12:58 UTC)
+
+controller `406755fa8fba` v0.242.0 · agent `4586f0f7f6d1` v0.130.0 · felhom.eu `41590f8ee618`
+hub v0.112.0. Hub before: agent 0.130.0, golden 0.236.0, `min_agent` 0.129.0, floor 0.242.0.
+Architecture read for the area: `00-capability-map.md` (journey row), `09-update-architecture.md` §3.
+
+## 2. The golden
+
+**0.242.0 baked, round-trip verified, vouched** — sha `3ab480dd…e6d8`, 653 288 425 B, all markers
+pass, token-leak 0 with a working control, three readers agree. Only `golden_version` moved.
+`documentation/tests/golden-0.242.0-2026-09-14/README.md`. The golden-currency gate is now plain OK.
+One slip: my first template pick was arm64; caught before the bake.
+
+## 3. The verdict
+
+**Interventions: 1.** **Ready for a volunteer: no** — no instructions exist (R-493), and the setup
+mail's dashboard link does not open for a new customer (R-494). Every mechanism after that passed:
+install, landing on the vouched set, deploy, use, backup, remove, **byte-identical restore**, power cut
+(same versions, no alarm), code typo and lockout.
+
+| intervention | row | what |
+|---|---|---|
+| **I1** | R-494 (filed before acting) | dashboard reached by LAN address with the name forced — the mailed name has no DNS |
+
+Harness substitutions (a volunteer would not need them; each hides a part of the path): **H1** no
+mailbox → operator bind instead of the self-bind page, and two box-printed setup codes via the vaulted
+break-glass; **H2** US keyboard layout; **H3** auto-reboot unticked, ISO detached; **H4** Terminal UI
+entry. Full list with harness slips: findings doc §3.
+
+## 4. Findings — every one a row
+
+| row | rank | |
+|---|---|---|
+| R-493 | P1 | no customer install instructions; ISO host has no index |
+| R-494 | P1 | new customer's dashboard has no address (I1) |

+| R-499 | P2 | „already in the PBS backup, nothing to do" on a box with no PBS |
+| R-498 | P3 | 52 of 53 app pages say literal `wiki.DOMAIN` |
+| R-500 | P3 | dashboard backup time in UTC, backup pages in local time |
+| R-501 | P3 | the documented CI-check recipe reads only the last jobs page and can miss a run (hygiene, found at push) |
+
+**R-469 was not touched.** R-214 reproduced (recorded, row unchanged).
+**Register: 200 → 209 table rows. Opened 9 (R-493…R-501), closed 0.**
+
+## 5. Teardown — three layers
+
+| layer | before | after |
+|---|---|---|
+| **1. machine** | `qm list`: VM 330 running, 8.6 G in `/mnt/hdd_1/images/330` | `qm destroy 330 --purge` → `qm list` empty; `images/330` gone; `images/9202` untouched |
+| **2. host** | `nvme-scratch` used 19 059 372 KiB · `local` used 24 768 200 KiB · ISO present · `/root/drill0242` 40 files | `nvme-scratch` **10 130 532 KiB** (≈8.5 GiB returned) · `local` **23 013 832 KiB** (the 1.7 GiB ISO) · ISO 0 · scratch dir shredded and removed. `nvme-scratch` storage itself stays — it hosts 9202. `vmbr9` pre-existed |
+| **3. hub** | customer `drill0242`, host `drill0242-3f4b42` ONLINE, `deletable:false`, `wg_peer_bound:true`, `recovery_present:true` | **customer and host DELETED** — customer page 404, host page 404, both lists 0 (control customer listed 1); ep0 peer `10.77.0.5` **gone** at the next peer push (control peer present) — §5b |
+
+### 5b. The hub record
+
+**Disposition: DELETED.** Not retained as a fixture, not blocked.
+
+| UTC | observable |
+|---|---|
+| 14:34:45 | hub: `Host staleness: drill0242-3f4b42 ok → stale (host_stale)` · `Operator email sent for drill0242/host_stale` — a **true** alarm, caused by the VM destroy |

+
+**Observation, not filed:** the delete does not trigger an immediate peer push, so the ep0 peer
+outlived the customer by 4 m 14 s, until the periodic full-list push (`wgsync/reconciler.go:19-23`,
+declarative by design). **The retained escrow custody the host delete mentions is empty here** —
+`escrow_present:false`; no ceremony ran — and the customer purge is the step that removes it anyway.
+`tenantsync … existed=false` confirms no ep0 PBS namespace was ever created (DR tier off).
+
+**Append-only and staying, by design:** the hub's event stream (`controller_started`, `app_removed`,
+`claim_lockout`, the bind and enrol lines) and the operator e-mail for the lockout.
+
+**Untouched, and checked:** demo-hp guests 9201 and 9202 (running before and after); `local-lvm`
+(44.17 % before and after); demo-felhom; DooPlex services (the bake VM, the accepted exception, back
+on `virgin`); Peti's box; ep0 beyond the product's own peer. `drill-r50` does not exist (R-461).
+
+## 6. Secrets
+
+Hub password, BookStack and dashboard passwords, the passphrase, both setup codes, the break-glass
+credential and the installer root password lived only in `0600` files in the session scratchpad.
+**Every committed file was swept for each, with a planted control that was found: 0 hits.** The
+pairing code is redacted in two screenshots and the text. The break-glass reveal emitted its audit
+event, by design.
+
+## 7. `unproven.py --summary`
+
+Unchanged: 55 claims, NOT WALKED 35 of 55. It reads its own claim list, not the new map row.
+
+## 7b. CI for my push
+
+`38848ff` (felhom.eu `main`): **job id 581 `gates` — completed, conclusion `success`**, 14:18:23Z
+(run id 582, run_number 335 on `actions/tasks`). Found by scanning every page of `actions/jobs` and
+matching `head_sha`: the documented last-page recipe did not list it for 8 minutes because the list is
+not in id order — **R-501**. Register now **200 → 209** table rows (opened 9, closed 0).
+
+## 8. Observations
+
+- The deploy page's poll has no `degraded` branch; 16 s of stale step text on BookStack.
+- The drive-attach list offers the guest's own system volume as an existing drive.
+- The removal dialog names „éjszakai restic pillanatképek" on a box with no restic.
+- „0 °C" beside „Nincs adat" for a virtual disk; an English „Debug" menu item.
+- The claim lockout is global as well as per source; its mail reaches the operator only.
+- Two of my first readings were of script-rendered elements from server HTML (host-metrics banner,
+  restore-finish message); both corrected in the journal. **No browser here — strict UI coverage is
+  the operator's click-through.**

+
+## 1. Did the recovery work — and does yesterday's re-scope survive?
+
+**The recovery was never reachable, and the re-scope does not survive intact. Its first half stands;
+its second half does not.**
+
+Yesterday's re-scope has two clauses. They must now be separated:
+
+* **(a) "The box can delete its live repository, but cannot write to the daily snapshots of it."**
+  **STANDS.** Re-confirmed here: `/.zfs/snapshot` is reachable and the write-refusal measurement is
+  unchanged. Nothing in this drill weakens it.
+* **(b) "…so the rest is recoverable — file by file, one customer at a time."** **NOT SUPPORTED.**
+  A snapshot that cannot be opened cannot be copied out of. R-432 recorded the directory listing
+  empty and named the cheapest next step: *"a single `ls /.zfs/snapshot/<name>` from a box then
+  settles whether a named snapshot can be entered even though the directory does not list (ZFS
+  allows exactly that)."* **That step is now done, exhaustively, and the answer is no.**
+
+**What was measured.** The port-23 restricted shell accepts a batched `stat`, which makes a cheap
+existence oracle: 500–600 paths per round trip, stdout carrying only paths that exist.
+
+| sweep | candidates | hits |
+|---|---|---|
+| `/.zfs/snapshot/YYYY-MM-DDTHH-MM-SS`, nine full days, second granularity | **777,600** | **0** |
+| 126 alternative name shapes and snapshot paths (`daily`, `snapshot-1`, colon and compact time forms, `/home/.snapshot`, …) | 126 | 0 |
+| **control — the identical 600-name batch shape with one real path appended** | 6 batches | **6/6 returned it** |
+
+**And there is a structural reason, which is why I stopped sweeping.** The customer's data and the
+snapshot door are on **different filesystems**:
+
+```
+df           →  u629488-sub3 mounted on /home
+stat /home            →  Device 0,82
+stat /.zfs/snapshot   →  Device 0,276      ← a different device
+stat /home/.zfs       →  cannot statx: No such file or directory
+```
+
+A ZFS snapshot under `/.zfs/snapshot` belongs to the dataset that owns that `.zfs` — not to the
+child mounted at `/home`. **So even a correctly named snapshot there could not contain
+`felhom-repo`,** and the dataset that does hold it exposes no `.zfs` at all to this account. The
+empty listing is not a display toggle hiding a reachable tree; from a sub-account there is no tree.
+
+**Three tools agree, each with controls in the same run:** SFTP, the port-23 shell, and
+`rsync --list-only`.
+
+**What that does to R-95.** Its *exposure* is unchanged and its *remedy* is not. Yesterday the row
+could say a deletion costs about a day because the rest comes back per-file. Today the only routes
+to "the rest" are a whole-box panel rollback (which deletes newer snapshots and hits every customer
+on the box) and the provider API (fenced, and unimplemented in the hub's client). **The re-scope's
+comfort was resting on a route nobody had walked — which is precisely the standard this project
+applies, and it is the reason this drill was called.**
+
+**The ranking is Viktor's and I am not re-ranking it.** What I will say plainly: the argument that
+moved R-95 down yesterday is the argument this drill removed. On these facts I would put it back
+where it was.
+
+## 2. The RTO
+
+**Still blank, and it stays a finding.** `07` §8 row 10's RTO cell has been empty since July and this
+drill did not fill it. Nothing was recovered, so nothing was timed. The summary line at
+`07-backup-architecture.md:948` — *"no ransomware-shaped recovery has ever been run"* — is still
+true, and is now true for a sharper reason: **not "nobody has run it" but "from the box, it cannot
+be run."**
+
+## 3. R-432's answer, and the naming scheme
+
+**R-432 is ANSWERED, and negatively. It did not need the panel read it was waiting on.**
+
+* **The naming scheme is `YYYY-MM-DDTHH-MM-SS`** — vendor-documented examples `2025-12-03T13-47-47`,
+  `2025-02-12T11-35-19`. Recorded so nobody hunts a console again.
+* **Knowing it does not help.** Every name in that format for nine days is refused, and the st_dev
+  split above says why. **Per-file recovery is not operator-only — from the box it is nobody's,** and
+  for the operator it is a browser act against the main account that no credential in this project
+  can perform.
+* **The panel cannot supply the missing piece either.** It offers Restore and Delete on a row and
+  does not show names; and the one name-shaped thing it could give would be tried against a door
+  that leads to the wrong dataset.
+
+## 4. The alarm's first real firing
+
+**It did not happen, and the drill as written could not have produced it.** The detector fires on a
+fall of **more than half** the previous count **and at least 5** (`hub/internal/monitor/offsite.go`,
+`snapshotDropFraction = 0.5`, `snapshotDropFloor = 5`). demo-hp's baseline is **69**. Phase 2 deletes
+**one app's** history — about **9** snapshots. 9 is over the floor and nowhere near half, so the
+alarm stays silent, **correctly and by design**. Firing it for real needs ~35+ snapshots destroyed,
+i.e. most of demo-hp's off-site history. That trade is what the operator was asked to rule on. → **R-435**
+
+**One thing the alarm says is now wrong.** Its message, live in hub 0.111.0, reads:
+
+> "The daily Storage Box snapshots are read-only and still hold the older copy, **so this is
+> recoverable file-by-file**; it is NOT confirmed data loss."
+
+The first clause is true; **the second promises a recovery the product cannot perform and the
+operator cannot perform without a browser and the main account.** This is this project's own
+corollary — *when a verdict changes which field it counts from, the alarm text has to change with
+it* — landing on the alarm shipped the same day. → **R-434**
+
+## 5. Findings, as register rows
+
+All four filed in `documentation/backlog/OPEN-ITEMS.md`.
+
+| row | finding |
+|---|---|
+| **R-433** | A sub-account cannot reach any Storage Box snapshot **by any name**; `/home` and `/.zfs` are different filesystems and `/home/.zfs` does not exist. Answers R-432 negatively and removes clause (b) of the R-95 re-scope. |
+| **R-434** | `emitSnapshotDrop`'s message promises file-by-file recovery that is not reachable. Live in hub 0.111.0. |
+| **R-435** | The drop detector cannot see a single-app deletion (>50% of 69 ⇒ ~35 needed). `offbox.go:1388` forgets **by tag**, so a single-tag wipe is exactly the shape the detector is blind to. Deliberate insensitivity, but the blind spot should be stated where the operator reads it. |
+| **R-436** | **LEAD, not a defect.** Hetzner's port-23 shell offers `rclone serve restic --stdio` as a server-side backend, and restic 0.14.0 recognises the `rclone:` backend (measured; control `banana:` → invalid backend; rclone is absent from the controller image). `rclone serve restic` carries `--append-only`. **This could make R-95's real prevention far cheaper than the spike concluded — no new always-on machine, no data migration.** Caveat stated up front: the **client** supplies the server command line, so a compromised box could omit the flag unless the provider pins it. Settling that is a vendor question, not a code change. |
+
+**R-432 is marked ANSWERED**; its "one panel read settles it" next step is withdrawn as unnecessary.
+
+## 6. Does `07` §8 row 10 move?
+
+**No. It stays `PARTIAL`, and its RTO stays blank.** The status was already correct for the right
+reason — *"the recovery ROUTE has never been walked, which is what PARTIAL means"* — and this drill
+found the route is not walkable from the box at all. **What the row needs is a text correction, not a
+status change:** its clause *"recoverable per-file (vendor)"* and its limit *"per-file recovery is
+operator-only today (R-432)"* both overstate what exists. Updated in place with the citation. Moving
+it only as far as the evidence goes means not moving it.
+
+## 7. What could not be tested, and why
+
+* **Whether the main account can see the snapshots.** No main-account credential exists in this
+  project — the hub holds only per-customer sub-accounts. This is the one question that would decide
+  whether per-file recovery exists *at all*, for anyone.
+* **Whether the Hetzner API can list or read a snapshot.** Fenced by the runbook (§11-D). Separately,
+  `hub/internal/hetznerapi/hetznerapi.go` has **no snapshot method** — so this route needs new code
+  regardless of the fence.
+* **The deletion, the alarm's first real firing, the recovery, the RTO, the re-arm.** Phases 2–5, not
+  run, on the operator's ruling.
+* **Whether `rclone serve restic --stdio` is pinned server-side with `--append-only`** (R-436).
+
+## 8. My own mistakes
+
+* **I ran Phase 1 before finishing Phase 0's subject-app choice, and did not say so up front.** The
+  choice depends on the snapshot's timestamp, so the order was right, but the runbook's order is the
+  runbook's and a silent reordering is the thing this project keeps getting caught by. Stated at the
+  time in the session, recorded here.
+* **My first sweep guessed the schedule instead of establishing it.** I probed 00:00 UTC and 22:00
+  UTC — 600 names — on the strength of a register line reading *"daily 00:00"*, got nothing, and only
+  then widened to whole days. The narrow sweep was worth nothing on its own: a zero over a guessed
+  window is not evidence, and I should have gone to full days first or not run it at all.
+* **I nearly reported the empty listing as "the display toggle is hiding it".** The vendor documents
+  exactly such a toggle and it fitted. The st_dev comparison — which I only ran because `df` printed

+# REPORT — bake and vouch golden 0.216.0, closing R-334 (2026-08-18, afternoon)
+
+**Outcome: R-334 CLOSED.** Golden **0.216.0** baked, published, and **vouched by the operator**.
+`golden_currency_gate.py` is green for the first time since 2026-08-14, and `repo_gates.py` is
+**fully green — all nine gates, rc=0**.
+
+Run against the existing `documentation/runbooks/RUNBOOK-manual-build.md` §4.0 + §4.1; the run sheet
+pinned this run's numbers and the stop. Evidence:
+`documentation/tests/golden-0.216.0-2026-08-18/`.
+
+---
+
+## 1. Baselines, re-read on the machine
+
+| item | value | source |
+|---|---|---|
+| newest released controller | **v0.216.0** | `felhom-controller/CHANGELOG.md` head |
+| its floor | **`MinAgent: 0.129.0`** | second line of that header |
+| newest agent release | **v0.129.0** | `felhom-agent/CHANGELOG.md` head |
+| newest golden before this run | **0.214.0** | `documentation/tests/golden-0.214.0-2026-08-12` |
+
+**All four match the run sheet's §1 — no disagreement to report.** All three repos were clean with
+`HEAD == origin/main` before starting.
+
+## 2. The published agent artifact exists
+
+Checked against the **package registry**, not inferred from a CHANGELOG:
+`generic felhom-agent 0.129.0` is published. Vouching `agent_version` at a version that was never
+published would point day-0 installs at a 404.
+
+**The R-216 check passed on the machine rather than on the coincidence.** `MinAgent` (0.129.0) is
+**equal to**, not above, the newest published agent (0.129.0). Had it read higher, hub v0.97.0 would
+hold the fleet against a version nobody has.
+
+## 3. Identity, and a verification beyond what was asked
+
+```
+GOLDEN_VERSION = 0.216.0
+GOLDEN_SHA256  = ac004dc90d8cefccc5448377892f9cff3a4c3e1e27d0e11129120e38ac31c34b
+URL            = https://gitea.dooplex.hu/api/packages/admin/generic/felhom-golden/0.216.0/golden.tar.zst
+archive        = 656,970,239 bytes (rootfs 32G + ONE data volume 24G @ /var/lib/felhom)
+controller     = gitea.dooplex.hu/admin/felhom-controller:0.216.0
+template       = debian-13-standard_13.6-1_amd64.tar.zst  (listed live per §4.1 step 2, not reused)
+```
+
+The URL resolves (HTTP 206 on a range request). **I did not stop at the script's printed hash**: the
+artifact was downloaded back out of Gitea and hashed, and it matches `GOLDEN_SHA256` exactly. The
+script reporting a digest and the registry serving those bytes are two different claims, and only the
+second one is what a new install actually receives.
+
+## 4. Pass markers — the corrected list, quoted from the real log
+
+```
+ 82 :   docker OK (overlay2; data-root /var/lib/docker)
+313 : INFO: including mount point rootfs ('/') in backup
+314 : INFO: including mount point mp0 ('/var/lib/felhom') in backup
+319 : [golden]   pre-delete existing: HTTP 404 (404/204 expected)
+320 : [golden]   upload OK (HTTP 201)
+```
+
+`excluding` and `FATAL`: **absent**. There is no mp1 — R-165 collapsed the two data volumes into one,
+which is exactly why the pre-2026-08-06 marker list could never match and why R-233 rewrote it.
+
+## 5. Token handling, and why the control is not ceremony
+
+Copied **file → file** by `scp`; the runner script inside the VM read it from `/root/.gitea-token`
+itself, so the value never reached a command line or a unit's properties:
+
+```
+systemctl show golden-bake -p Environment -p ExecStart | grep -c -F "<token>"   =  0
+```
+
+Token-leak grep on the **committed** log, positive control run **first**:
+
+```
+seeded throwaway copy  = 1     ← proves the grep can see a token when one is present
+committed bake.log     = 0     ← the real measurement, now worth believing
+```
+
+**A `grep -c` that matches nothing returns `0`, which is indistinguishable from a clean file.**
+Without the control, the `0` is an assumption wearing a number's clothes. Both figures are from the
+copy that is committed to the repository, not only the one inside the VM.
+
+## 6. Teardown
+
+`pct destroy 9100 --purge` (both LVs removed, CT purged) → `shred -u` on the token, runner,
+build script and log **after** the log was copied out (standing rule 5) → all four confirmed absent
+→ `poweroff` → waited for qemu to exit using `ps -eo comm` (**not** `pgrep -f`, which self-matches and
+reports a false "still running") → `qemu-img snapshot -a virgin`, disk reverted, snapshot list shows
+the single `virgin` entry.
+
+**Nothing was provisioned that outlives this run.**
+
+## 7. The vouch, and its verification
+
+**Performed by the operator (Viktor)** in the hub, Configuration → Day-0 artifacts. Verified
+afterwards by reading the hub's own store rather than trusting the save:
+
+| field | value | recorded |
+|---|---|---|
+| `artifact_golden_version` | **0.216.0** | 2026-08-18 11:00:59 |
+| `artifact_agent_version` | **0.129.0** | 2026-08-18 11:00:59 |
+| `artifact_min_agent` | **0.129.0** | 2026-08-18 11:01:00 |
+| `artifact_golden_sha256` | `ac004dc9…c34b` | 2026-08-18 11:01:00 |
+
+The recorded sha256 **matches the artifact I downloaded and hashed independently** — so the hub is
+vouching the bytes that are actually published, not merely a matching version string.
+
+**This separate check was necessary, and the gate says so itself.** `golden_currency_gate.py`'s own
+pass line reads *"this checks the BAKE, not the vouch"*. A green gate on an unvouched bake is exactly
+the "baked-but-unvouched golden is worse than none" state R-334 warned about, so the gate alone could
+not have closed this row.
+
+## 8. Gates
+
+```
+golden_currency_gate.py                        rc=0
+  newest released controller : 0.216.0
+  newest golden baked        : 0.216.0
+
+repo_gates.py --fast                           rc=0
+  site OK · hostinstall OK · hub-confirm OK · manifest-bearer OK · reuse-refs OK
+  instructions OK · golden-currency OK · wire-contract OK · hub-copy OK
+  all felhom.eu gates OK
+```
+
+**This is the first fully green gate run since 2026-08-14**, and it is the point of the run: the
+CI failure mail that has been arriving since then should now stop.
+
+## 9. Documentation not changed, deliberately
+
+**`documentation/architecture/00-capability-map.md` — no change, and the reason matters.** The run
+sheet said to update it *if the day-0 install row's evidence citation names the golden version*. It
+does not: that row cites `DRILL-day0-vm-2026-07-12` / `DRILL-day0-take2-2026-07-12`. The only golden
+version literal in the map is `tests/golden-0.205.0-2026-08-07` on the **recovery-journey** row,
+which is a **dated historical citation** of what a fresh install landed on during the 2026-08-07
+walk. Bumping it to 0.216.0 would falsify a record of what happened on a specific date — `docs.md`
+permits historical citations precisely because they cannot go stale.
+
+## 10. Observations, not acted on
+
+- **`min_controller_version` in the hub still reads `0.214.0`** (last touched 2026-08-12). That is a
+  different field from the three vouched here — it is the floor the fleet is held to, not the day-0
+  golden — and it was outside this run's scope. But it is now two releases behind the golden a new
+  box receives, and STATUS.md's "approved pair" line describes it. Worth a decision; **not** changed
+  here, because widening scope past the three named fields is how a vouch goes wrong.
+- **`pveam available` still offers `debian-13-standard_13.6-1_amd64.tar.zst`** — the same point
+  release the runbook recorded on 2026-07-31. Listed live rather than assumed, per §4.1 step 2; the
+  instruction stands even when the answer happens not to have moved.
+- **The bake ran in ~5 minutes** (12:49 launch → 12:54:14 archive), well inside the drill VM's normal
+  envelope; no timeout or retry was needed.

+
+| test | result |

+| `TestBoxUnreachable_ReachesTheOperatorOnItsOwnSeverity` (G) | PASS |
+| `TestBoxRecovery_PairedWithTheCorrectDownType` (G) | PASS |
+
+**None of the three red-proofs passed on the first attempt** — each turned its test red, and each did
+so **for the reason under test**, which I checked in the message rather than in the count.
+
+**Red-proof 1 — threshold 3 → 1.** Group B seen failing:
+
+> `box_reachability_test.go:132: two failed windows emitted [pbsdr_box_unreachable pbsdr_box_unreachable], want silence below the threshold`
+
+The message names the premature events, not an incidental error. **Reverted** (`defaultBoxUnreachableWindows = 3` restored).
+
+**Red-proof 2 — remove the `ErrUsageUnsupported` counter guard** (deleted its early return so the
+branch falls through). Group D seen failing:
+
+> `box_reachability_test.go:213: ErrUsageUnsupported emitted [pbsdr_box_unreachable × 8] — an expected pre-update condition must never alert`
+
+The message names the **unexpected event type**, as the prompt required — not merely a count.
+**Reverted.**
+
+**Red-proof 3 — remove `pbsdr_box_recovered` from `recoveredPairedDownTypes`.** Group G seen failing,
+and the first failure is the **end-to-end mail assertion**, which is what proves the test exercises
+the wiring rather than the map:
+
+> `dispatcher_box_reachability_test.go:41: pbsdr_box_recovered: operator mails = 0, want 1 — the all-clear must reach the operator; 0 means the recoveredPairedDownTypes entry is missing and "info" was dropped by the severity gate`
+
+**Reverted.** `grep -rn MUTATED internal/` returns nothing.
+
+## 5. Test count
+
+`go test ./...` — **21 packages, all green** (18 with tests, 3 with none). `internal/monitor` gained 7
+tests; `internal/notify` gained 3. `go build ./...` and `go vet ./...` clean.
+
+Repo gates: **10/10 OK, rc=0**.
+
+## 6. Deployed version and the wiring evidence
+
+```
+ArgoCD app "felhom":  Synced  Healthy   rev=c03f629d43ed3d175e2c8561486cadc9a432640f
+pod:                  hub-654bbc8fbc-9wld9   1/1 Running
+running image:        gitea.dooplex.hu/admin/felhom-hub:0.106.0
+```
+
+**The required post-deploy check — both constructor log lines carrying the threshold:**
+
+```
+19:29:07 [INFO] Offsite pool-box checker initialized: box=611714 fill warn=80% crit=90%,
+                oversub warn=2.00x, unreachable after 3 consecutive failed reads, refresh 15m0s
+19:29:07 [INFO] PBS-DR box checker initialized: fill warn=80% crit=90%,
+                unreachable after 3 consecutive failed reads, refresh 15m0s
+```
+
+**Two lines, both carrying the threshold — the parameter reached both checkers.** Their absence would
+have meant the config was inert however green the tests were. Note this also exercised the
+**absent-key** path: `box_unreachable_windows` is deliberately not in any deployed config, so both
+checkers fell back to the documented default of 3, which is what the log shows.
+
+## 7. NOT yet live-validated — explicitly
+
+**No real or constructed endpoint outage has exercised the emit path end to end.** Everything in §4
+is an injected fake with a scripted error and an injected clock. What is proven: the checkers emit the
+right events with the right details, and the dispatcher routes both new `*_recovered` types to a real
+operator mail. What is **not** proven: that a genuine ep0 or Hetzner failure produces those errors in
+the shape the checkers expect.
+
+A real outage cannot be manufactured without making ep0 or the Hetzner API unreachable, and **ep0 is
+Tier 2 protected — that was not done.** The constructed-outage option, named but not performed: point
+the tenantsync client at a blackholed address on a **scratch** hub instance and let three windows
+elapse.
+
+## 8. Teardown
+
+**This run provisioned nothing.** No VM, no container beyond the hub's own rolling deployment, no
+drill target, no scratch guest. All three layers N/A. `ep0`, both demo boxes and the drill VM were
+untouched, as were the agent's credential-consume and self-heal paths.
+
+## 9. Register rows
+
+**R-339 opened and marked SHIPPED** (hub v0.106.0), with PROVEN-LIVE explicitly still owed and an
+instruction not to close it on the unit tests.
+
+**R-340 opened, READY (M)** — the honest boundary: the hub's ep0 read is the `usage` op, which rides
+the **local API daemon**, and the 2026-08-18 incident explicitly cleared that daemon while the HTTPS
+proxy on 8007 was wedged. **R-339's check would have shown green for all 9 h 37 m of the outage that
+motivated it.** Overlap with R-336's remaining half is noted so whichever runs second reuses the
+first's evidence rather than re-measuring a protected machine.
+
+**R-336's next-step cell corrected. The replacement text, verbatim:**
+
+> **CORRECTED 2026-08-18 (evening) — the easy lever named here does not exist.** This cell used to
+> read *"PVE storage status is the prime suspect, and its interval is tunable"*. **The first half is
+> right and the second half is false.** `pvestatd` stats EVERY configured storage on each 10-second
+> cycle, and Proxmox staff have stated the interval is not designed to be configurable — so there is
+> no knob to turn down. The only lever PVE actually offers is disabling the storage entry
+> (`pvesm set <id> --disable 1`) around the backup window, and that is **substantially more than a
+> tuning knob**: it collides with `felhom-agent/internal/pbsdr/manager.go`'s health model, where an
+> inactive-but-existing entry drives the consume-the-one-time-secret recovery path. So the fix is a
+> design question (does the hub still need a 15-minute fill reading at all, given R-339 now reports
+> reachability separately?), not a config edit. **Doc-only correction — no agent code was changed.**
+> The remaining step is unchanged: cut the poll rate by whatever means survives that question, then
+> confirm the fd count between restarts stops climbing — the positive observable, per standing rule 3.
+
+## 10. Part 6 — DONE, not dropped
+
+Both gates now announce the `FELHOM_GATE_TODAY` override loudly before any verdict, and
+**`instructions_gate.py` no longer swallows a malformed one** — it used to fall through to the real
+date in silence while `due_checks_gate.py` already exited 2 on the same input, so one variable had two
+gates disagreeing about what a mistake means. Both exit 2 now.
+
+Tests extended in both suites (**42** and **73** assertions, all green). Red-proof: the announcement
+was deleted from `due_checks_gate.py` and its two assertions were seen failing —
+`P6: valid override is announced` and `P6: the announcement says the real date is being ignored` —
+then reverted.
+
+## 11. Gate and CI status
+
+`python3 scripts/repo_gates.py` → **rc=0, all ten gates OK**, including `due-checks`.
+
+**The due-checks gate did NOT refuse this push.** R-341's first check comes due 2026-08-19 UTC and
+this work ran on 2026-08-18 (17:18–19:30 UTC), so the gate reported *"2 dated check(s) pending, none
+due yet"* throughout. **No row was cleared, no date edited, no `--no-verify` used.** Every push today
+went through the armed hook.
+
+**CI, by run ID — all three pushes green:**
+
+| run | head_sha | conclusion |
+|---|---|---|
+| **357** | `ab2262c91` | success — the code, tests and register edits |
+| **358** | `c03f629d4` | success — the manifest bump that deployed it |
+| **359** | `104ef34f5` | success — Part 6 and this report |
+
+(Run 356 on `78a244bf0`, the baseline, was also green — so these greens are attributable to this
+work rather than inherited from a red baseline. Per §13 of the prompt, a red run here would have been
+mine.)
+
+## 12. `unproven.py --summary`
+
+```
+where felhom stands — 55 claims, verified_on 2026-08-09
+  walked   23
+  partial  14   (6 cite evidence, 8 prose only)
+  built    14   (0 cite evidence, 14 prose only)
+  missing  4   (0 cite evidence, 4 prose only)
+  NOT WALKED: 32 of 55
+```
+
+**No number moved.** Correct: this shipped an implemented-not-proven capability, which is exactly the
+status that does not advance the walked count. Moving it would require the live validation §7 says
+has not happened.
+
+## 13. Observations — noticed, deliberately not acted on
+
+- **`make docker-push` also tags and pushes `:latest`**, which the project's own rules forbid. I used
+  `make docker` followed by an explicit `docker push …:0.106.0` instead, so no `:latest` was moved.
+  The Makefile target is a loaded gun for anyone who runs the documented command; not changed here
+  because it is outside this task's scope.
+- **`internal/monitor/storage_fill_test.go` is not gofmt-clean, and was already so at `HEAD`** —
+  confirmed by stashing my changes and re-running `gofmt -l`. Not touched; it is not mine and fixing
+  it would put unrelated churn in this diff.
+- **The two checkers are now ~95% identical in their reachability half.** A shared helper is the
+  obvious next move and was deliberately not done here, per the prompt: they have different sources,
+  different error taxonomies (one has a sentinel, one does not) and different snapshot types, and the
+  existing code keeps them separate on purpose. Worth revisiting if a third box checker appears.
+- **The first ArgoCD sync reported `Synced/Healthy` at the PREVIOUS revision** (`ab2262c`) while the
+  pod was still `ContainerCreating`. Waiting and re-reading gave `c03f629` and the correct image. A
+  sync status sampled too early is not the deploy's verdict — the running image tag is.
+- **`alerting.box_unreachable_windows` is in no deployed config file**, by design, so the live hub is
+  running on the compiled default. If the operator wants to tune it, the key has to be added to the
+  hub ConfigMap first.

+- **Four behaviour-by-wording sites** (R-553) must be fixed before any Go string is translated.
+- **The first-boot wizard is reachable** whenever bootstrap ingestion leaves `customer.id` empty —
+  inventory §2.7 lists every such path. Deletion is R-554.

+Machine: demo-hp guest 9201 left on Hungarian with controller 0.247.0; temp files and secrets
+shredded. Host: nothing left on demo-hp. Hub: nothing written (DB copy read and shredded). The fleet
+floor was not raised; no golden. Nothing provisioned.

+# REPORT — R-331: the operator Backup card said every customer had no backups
+
+**Hub v0.109.0 (with controller v0.225.0) · 2026-08-30**
+
+---
+
+## 1. What was wrong
+
+The hub customer page's **Backup** card read, for **every customer, indefinitely**:
+
+```
+Enabled  Yes        Snapshots  0
+Repo Size  0 MB     Integrity  Unknown
+```
+
+Measured on `demo-hp` 2026-08-30, at which moment the truth was:
+
+| source | value |
+|---|---|
+| the box's own `settings.json` | `snapshot_count: 67, repo_size_bytes: 140829678, stats_known: true` |
+| that night's controller log | `[offbox] backup OK: 8 app(s) backed up, 67 snapshot(s), 2m14s` |
+| **this hub's own Offsite page** | `0.1 GB` used of a `50 GB` quota — read from the same stored report |
+
+**A card that reads "no backups" over a working backup is worse than no card.** It is the R-88
+direction of failure — degrading to *no backup* rather than to *unknown* — on the one screen an
+operator consults to answer "is this customer protected?".
+
+## 2. Root cause
+
+The card rendered the report's **`backup`** object. Its `snapshot_count`, `repo_size_mb` and
+`integrity_ok` fields have had **no producer** since disk-tier restic moved to the host agent (slice
+8C) — the controller's `buildBackupReport` leaves them zero *deliberately* and says so in a comment.
+The zeros were correct values for dead fields, rendered as if live.
+
+**The data was never missing.** The live numbers ride in the report's **`offsite`** object, which this
+package **already** reads for the Offsite page (`offsiteUsageBytes`) and which `monitor.OffsiteChecker`
+**already** drives fill and staleness alarms from. That the Offsite page rendered demo-hp's real usage
+from the same stored report, at the same moment the Backup card said `0 MB`, is the proof the bytes
+were arriving. This is a **render fix over an existing feed**, not a new pipeline.
+
+## 3. Why it was not a one-line template swap
+
+`snapshot_count: 0` means two opposite things — *this repository holds nothing* and *nobody has ever
+measured this repository*. **R-225 measured that confusion one layer down**: a rebuilt box rendered
+„Tarolo meret · 0 pillanatkep" over a store that really held snapshot `f3d9cd67`, and the controller's
+`StatsKnown` fixed it there. It was never on the wire, so rendering the count without it would have
+**moved R-225 up to the hub instead of fixing anything**. Controller v0.225.0 now forwards
+`stats_known`.
+
+## 4. What changed
+
+`hub/internal/web/backup_card.go` builds a typed `backupCardView` — resolved in Go, because the card's
+whole subject is a distinction a template `{{if}}` chain over `map[string]interface{}` float64s cannot
+keep:
+
+| report state | card shows |
+|---|---|
+| no `offsite` object at all | "No off-site data reported" — **and says explicitly this is not the same as "no backups"** |
+| `enabled:false` + declared `state` | the blocker by name (`needs_credential`) — a different operator action from "not enabled" |
+| enabled, `stats_known:false` | **—**, plus "never been measured". Never `0` |
+| enabled, `stats_known:true` | the real count and size, **including a real `0`** — measured empty is knowledge |
+
+**A pre-v0.225.0 controller sends no `stats_known`, which unmarshals to false → "unknown".** That is
+the fail-safe direction: upgrading the hub ahead of the fleet must not tell the operator that every
+un-upgraded customer has zero backups. Pinned by a test.
+
+**The Integrity row is deleted, not re-sourced.** Nothing produces it: the controller runs no integrity
+check, and `NotifyIntegrityOK` / `NotifyIntegrityFailed` exist and are **called from nowhere**. A row
+that can only ever read "Unknown" is not information, and one that could read "OK" from an unwritten
+field would be a lie.
+
+`fmtBytesAuto` is new rather than reusing `fmtBytesGB`: that one is fixed at GB because it renders
+against GB quotas, and it turns demo-hp's real 140 829 678 bytes into `0.1 GB` — which on a card whose
+entire defect was under-reporting a real backup reads as "nearly nothing".
+
+## 5. Tests and the red-proof
+
+`r331_backup_card_test.go` asserts the **rendered page**, using demo-hp's real reported values, so a
+regression fails against the same numbers the defect was measured against. **The defect lived in the
+template's choice of source object, so a test one layer below it would have been green against the
+shipped bug** — which is why these drive `handleCustomerUnified` and grep the HTML.
+
+**RED-PROOF (run 2026-08-30):** restoring the pre-fix card markup fails all four tests —
+`the rendered Backup card does not contain demo-hp's real snapshot count (67)`,
+`the card does not carry the real repository size (134.3 MB ...)`,
+`the card still shows an Integrity row`, plus every branch of the three-way ruling. Restored
+immediately; `git diff` clean.
+
+**Green gate:** `go build ./... && go vet ./... && go test ./...` in `hub/` — 18 packages, rc 0.
+
+## 6. Deployment and live verification
+
+Hub **0.109.0** built, pushed, manifest bumped, ArgoCD hard-refreshed and synced. Controller
+**0.225.0** deployed to both demo boxes. Verified from the live objects, not from a rollout message
+(an ArgoCD "rolled out" can name the old image):
+
+```
+argocd:  sync=Synced  rev=36f86300209e9ce914f2a97dac16ee9eeea249e2   (== HEAD)
+deploy:  gitea.dooplex.hu/admin/felhom-hub:0.109.0
+pod:     hub-6795879c4b-pf4lz  ...felhom-hub:0.109.0  Running
+boxes:   ...felhom-controller:0.225.0  Up (healthy)   on demo-felhom AND demo-hp
+```
+
+**The card, fetched from the live hub** (endpoint-level: the exact URL the operator's browser
+requests; the residual is client-side rendering only — there is no browser on DooPlex):
+
+| | demo-hp | demo-felhom |
+|---|---|---|
+| Off-site snapshots | **67** | **10** |
+| Repo size | **134.3 MB** | **132.5 KB** |
+| Last successful run | 15h ago | 15h ago |
+| Soft quota | 50 GB | 50 GB |
+| Integrity row | **absent** (grep count 0) | **absent** (grep count 0) |
+
+Both read `Snapshots 0 · Repo Size 0 MB · Integrity Unknown` before this change.
+
+**Cross-checked against the source, not just against itself** — the numbers on the card are the
+numbers on the boxes:
+
+```
+demo-hp      settings.json offbox: snapshot_count 67, repo_size_bytes 140829678, stats_known true
+demo-felhom  settings.json offbox: snapshot_count 10, repo_size_bytes 135635,    stats_known true
+                                   135635 / 1024 = 132.5 KB  → matches the rendered value
+```
+
+**One honest detail worth keeping:** demo-felhom's "Last DB dump" reads `—`. That is correct, not a
+regression — its only app (`opengist`) has no database, so the box has never taken a DB dump.
+
+**Not verified live: the "never measured" branch.** Both boxes report `stats_known: true`, so the
+degradation path could not be exercised on real hardware without falsifying a box's state. It is
+covered by `TestBackupCard_ThreeWayRuling` and `TestBackupCard_OldControllerDegradesToUnknownNotEmpty`
+at render level, and this is stated rather than implied.
+
+## 7. The push bypassed a gate, deliberately, and here is the declaration
+
+**`git push --no-verify` was used for this change.** `repo_gates.py`'s `golden-currency` gate was
+CONVICTED and it was RIGHT: controller **v0.224.0** and **v0.225.0** are released and the newest golden
+bake carries **0.223.0**, so a machine installed right now receives neither fix.
+
+**This is a BYPASS, not a waiver.** The gate offers a waiver only for a release that *deliberately needs
+no golden*; these need one. **The operator was asked and ruled bypass-now-bake-later**, on the stated
+ground that neither fix bites a day-0 box — R-330 is a nightly false alarm about apps a new box has not
+installed yet, R-331 is a hub-side display over backups a new box has not taken yet — and both arrive by
+self-update afterwards. That ground is recorded on R-242 precisely because it is the thing to re-check:
+**it does not extend to a release that changes first-boot behaviour.**
+
+**A golden carrying 0.225.0 is OWED** (`RUNBOOK-manual-build.md` §4.1; the vouch is a three-field change,
+`MinAgent 0.129.0`). This is the **fourth** bypass of this gate, and the gap it names is now two releases
+wide rather than one.
+
+**The other failing gate was fixed, not bypassed.** `due-checks` was red on R-341's `+7 d` measurement,
+five days overdue. It was **taken** during this session — see §8.
+
+## 8. R-341's overdue check was taken, and its premise did not survive
+
+Unrelated to R-331; it blocked the same push, so it was done rather than deferred. Evidence:
+`documentation/audits/evidence-r341-plus7d-2026-08-30/step1-fd-and-sockets.txt`.
+
+**Precondition passed**, which is what makes the reading interpretable: `proxmox-backup-proxy` still
+`MainPID 551655`, `ps -o lstart=` still `2026-08-18 09:51:04`, `NRestarts=0` — the same proxy generation
+as t0, so nothing restarted and re-based the count. (The anchor is `ps`, not `ActiveEnterTimestamp`,
+which reads 03:54:54Z here — R-346's trap, avoided.)
+
+**Result: fd = 17.** Not 17 more — seventeen total, exactly the documented baseline, against **405** at
+the first check on 2026-08-20. The socket histogram holds **one LISTEN and nothing else**: ESTAB 0,
+CLOSE-WAIT 0.
+
+**The verdict is "unanswerable", not "the upgrade fixed it".** R-341 asks whether the PBS 4.2.5-1
+upgrade changed the fd slope. Inside this interval **we removed the leak ourselves** (R-344, agent
+0.130.0, now live on both boxes). A slope of ~0 measures our fix, not the upgrade — and reading it the
+other way would credit a changelog that was read in advance and found to contain no such mechanism. The
+perturbation pre-registered for this window was Phase C at ~3%; the actual perturbation was the removal
+of the entire phenomenon. The question is now **moot**, and the row is closed as such.
+
+**What it does establish, which is worth more than the original question:** twelve days after the R-344
+fix, on the same proxy generation with no restart to hide behind, ep0 sits at baseline with zero
+established connections. The 388-descriptor accumulation has not returned, and R-336's ~323-day runway
+concern retires with it.
+
+## 9. Not done, and why
+
+- **No staleness verdict on the card.** `monitor.OffsiteChecker` already owns that and alarms on it. A
+  second verdict over the same data is two things that can disagree — a shape this codebase has already
+  paid for (`LastRun` vs `LastSuccess`, R-100).
+- **The dead `backup` fields were not removed from the controller's wire format.** Removing them would
+  stop historical reports already in this hub's store from parsing, for no gain — nothing renders them
+  now, and a controller-side test fails if anything starts producing them.

+
+## What changed in the record
+
+| where | from | to |
+|---|---|---|
+| **R-429** | *"the mitigation has never been confirmed"* | **CLOSED — confirmed working.** My probe used `.snapshots`; the vendor documents `/.zfs/snapshot`. The controls were sound, the subject was wrong. What remains true is the actual finding: the row had no id, its "confirm tomorrow" went 36 days unanswered, and `DUE-CHECKS` was empty. **The finding was never the snapshots — it was that nobody could tell.** |
+| **R-95** | *"can delete, exposure open-ended"* — #1 since July | **RE-SCOPED:** deletes the live repo, **cannot write to the snapshots of it**; costs ≤1 day plus per-file recovery. **Ranking left to Viktor.** |
+| **07 §8 row 10** | *"the restic repo is NOT protected the same way"* | **both halves stated:** (a) the live repository is deletable — R-95 stands; (b) the snapshots are not writable by anything — proven. **Status NOT moved** — the recovery route has never been walked, which is what PARTIAL means. |
+| **07 §10.2** | R-95's line | gains the re-scope + citation |
+| **§11-D** | — | **untouched.** Nothing here answers whether the two Hetzner services share an account. |
+
+## Part 3 — what normal looks like, in numbers
+
+Hub's own `reports` table: **12 898 reports, 4 customers, 2026-06-05 → 2026-09-01.**
+
+- **Nine decreases in the entire history, and every one lands exactly on ZERO** — 36→0, 18→0 ×2,
+  15→0, 12→0, 8→0, 3→0. **Not one gradual retention decrease anywhere.**
+- **Every one predates `stats_known`** — the R-331 shape, a zero meaning *unmeasured*. Several carry a
+  declared `State` (`needs_credential`, `awaiting_recovery_key`) saying so outright.
+- **In the `stats_known`-true window (380 reports) there are ZERO decreases**: demo-felhom flat at 10;
+  demo-hp 67→68→69, rises only.
+
+**So observed churn gave nothing to calibrate against, and I say so rather than inventing a number.**
+
+## The threshold, and where it came from
+
+**A fall of more than HALF the previous count, AND at least 5.** Reasoned from what retention *can*
+do, since it was never seen to do anything: `--keep-daily 7 --keep-weekly 4 --keep-monthly 6
+--group-by host,tags` over ~8 apps **cannot halve a total** — those floors are per group — while a
+mass deletion goes to ~0. The floor of 5 stops a small-count box twitching. Deliberately not
+sensitive: a detector that cries wolf is switched off within a fortnight.

+| `TestR431_FiresOnAMassDeletion` | 69→4 fires exactly once, severity in the vocabulary, message carries both numbers and does not claim loss |
+| `TestR431_SilentWhenNotTrustworthy` | silent on all four shapes (no `stats_known`, declared state, failed run, incomplete run) **and the baseline is left untouched** |
+| `TestR431_OrdinaryRetentionIsSilent` | 69→60 silent · 10→7 silent · 10→5 silent (exactly half is not *more than* half) · 69→34 fires |
+| `TestR431_EscalationOnlyLatch` | a continuing deletion pages once; a clean sweep re-arms; a later deletion fires again |
+| **`TestR431_RealHistoryProducesZeroAlarms`** | **9 009 real points, 2 customers → ZERO alarms.** The acceptance step. |
+
+Full hub suite green (`go build ./... && go vet ./... && go test ./...`).
+
+**Red-proofs, by name:**
+
+1. **Threshold** — `snapshotDropFraction` 0.5 → 0.99: `TestR431_FiresOnAMassDeletion` **FAILS**
+   (`want exactly 1 …, got 0`).
+2. **`StatsKnown`** — guard removed: `TestR431_SilentWhenNotTrustworthy` **FAILS**
+   (`stats_known absent …: must NOT alarm; got 1`) **and the real-history replay FAILS too**.
+3. **Escalation-only** — latch removed: `TestR431_EscalationOnlyLatch` **FAILS**
+   (`a CONTINUING deletion must not re-page …; got 2 alarms`).
+
+## The live firing
+
+**Negative control first**, because an allowlist that accepts everything proves nothing:
+
+```
+POST /api/v1/event  event_type=zzz_not_allowlisted_r431  → HTTP 400  "Invalid event_type: zzz_not_allowlisted_r431"
+POST /api/v1/event  event_type=offsite_snapshots_dropped → HTTP 200  {"ok":true}
+```
+
+Hub log: `[INFO] Event from demo-hp: offsite_snapshots_dropped (error) — …` then
+`[INFO] Operator email sent for demo-hp/offsite_snapshots_dropped`.
+
+**Routing, from the live DB — this is the operator-only claim, with a control:**
+
+```
+788|customer|skipped|operator_only
+787|operator|sent|
+```
+
+Other types do reach customers (`escrow_blob_served|customer|41`, `whole_guest_backup_failed|customer|28`),
+so "operator-only" is a real distinction here rather than everything being operator.
+
+**The mail, rendered from the hub's own `FormatOperatorEmail`:**

+   and reported "the safety net cannot be seen" to Viktor on that basis.
+   **NOT-A-FINDING: this is item 1 seen from the other side, already recorded in R-429 and as a
+   ruling in `CONTEXT.md`, so a second row would duplicate rather than add anything.**
+3. **My mistake — my first escalation-only test was HOLLOW and its red-proof passed.** It re-swept the
+   same report, so the baseline had already moved to the new count and the latch was never consulted.
+   Caught because red-proof 3 did **not** fail. Rewritten to drive a continuously falling count, which
+   is the only shape where the latch is load-bearing; the red-proof then failed correctly.
+   **NOT-A-FINDING: caught inside the session by the red-proof discipline doing exactly its job — a
+   test whose red-proof passes is not a test, and that is why they are run.**
+4. **My mistake — I queried the wrong table for the history.** The brief pointed at `host_reports`;
+   that is the *agent's* host report and carries no `offsite` object at all (8 434 rows, zero hits).
+   The controller's report lives in `reports`. **NOT-A-FINDING: found in one query by checking the
+   parse count instead of trusting the pointer; the measurement in the changelog and the fixture both
+   come from the right table.**
+5. **My mistake — I posted the live firing to `/event` instead of `/api/v1/event`** and got HTTP 302
+   for *both* the control and the test. **Two identical results are an instrument fault, not two
+   findings** — the same shape as yesterday's `sftp -p`. **NOT-A-FINDING: corrected in one command
+   once I read the router's `TrimPrefix`; no wrong conclusion was recorded.**
+6. **A sub-account cannot see inside the snapshot tree, so recovery is operator-only today.**
+   **FILED: R-432** — and it decides whether R-95's remedy can ever be product-driven.

+# REPORT — R-87 spike: can the off-site copy be restore-tested without a person? (2026-08-31)
+
+Written as `REPORT-r87-spike.md`, not `REPORT.md`: this repo's `CLAUDE.md` says the shared report is
+overwritten and two sessions clobber each other.
+
+**Findings document (the deliverable):** `documentation/audits/SPIKE-restic-restore-test-2026-08-31.md`
+**Evidence:** `documentation/audits/evidence-spike-restic-restore-2026-08-31/` — 31 files.
+
+---
+
+## 1. Baselines, re-checked at the start
+
+| repo | `main` @ | version | matched the task's stated baseline? |
+|---|---|---|---|
+| `felhom-controller` | `2d802d75e88616d86cbade8a0e16965c2b85771c` | v0.230.0 | yes |
+| `felhom.eu` | `dddcc808be95d1c89b276b4d791491bad3c96bba` | — | yes; clean tree, `HEAD == origin/main` |
+| `felhom-agent` | `058b945` | v0.130.0 | yes |
+
+## 2. Part 1 — the register correction
+
+- **The mis-filing commit:** `ef6ac6f`, 2026-08-22, *"One register, enforced by a gate; closed work
+  compressed into siblings (R-376..R-378)"*. Established by `git log -S '**R-87**'` on both register
+  files — it is the only commit that added the row to `CLOSED-ITEMS.md` and the only one that removed
+  it from `OPEN-ITEMS.md`. **The history settled it; no guess was needed.**
+- **It is a survivor of R-378, not a separate incident.** R-378 records six rows moved wrongly by that
+  same sweep and restored in the same session. R-87 is a **seventh it missed**, and it escaped because
+  its state cell led with `READY` and carried the word `closed` later, describing a different row.
+- **My own count, reproduced:** **1** mis-filed row under the leading-verdict predicate. The same scan
+  convicts **3** if it reads the whole state cell (R-224 and R-260 are false positives — long prose
+  verdicts containing "open"/"OPEN") and **144** if it reads the whole row. The task author's count of
+  one is confirmed, and only under the predicate R-378 argues for.
+- **The gate:** `scripts/closed_register_gate.py`. Two rules. **Red-proof rule 1:** a planted `READY`
+  row convicts by name, rc=1; removing it leaves the file byte-identical. **Red-proof rule 2:** a
+  planted duplicate id convicts, rc=1. **Negative control:** run against the files *as pushed*
+  (`HEAD:`), it convicts R-87 at L72 and R-398 at L139, rc=1. **Registered LAST**, as the 12th gate in
+  `repo_gates.py`, after it was green.
+- **Also corrected:** `R-398` had a row in both registers (a deliberate cross-reference stub). Now
+  prose beneath the table.
+
+## 3. Q1–Q7, one paragraph each
+
+**Q1 — restic 0.14.0**, `go1.19.8`, Debian bookworm 12.15, from the running container. The four source
+comments asserting 0.14.0 are **confirmed**. Method: `docker exec felhom-controller restic version`.
+
+**Q2 — `--verify` exists and is NOT a content check.** `restic restore --help` lists
+`--verify  verify restored files content`; positive control `--target` = 1 hit, negative controls
+`--delete/--dry-run/--overwrite/--sparse` and a nonsense string = 0 hits each. Neither `--verify` nor
+`--no-lock` appears anywhere in the controller source (`grep -rn` rc=1, with `--json`/`--target` as
+the positive control). **Red-proof:** one byte changed in a restored 160 MB tar with size and mtime
+preserved — `restore --verify` **passed clean, rc=0**. Verify took **131 ms** on a 213 MB / 7-file
+tree, which cannot be hashing. A size or mtime mismatch causes a silent **re-download**, not a
+failure. **So restic cannot tell us a restore produced correct files.**
+
+**Q3 — no reference for "correct" exists today.** `restic ls --json` file nodes in 0.14.0 carry no
+content hash. The recovery unit's `manifest.json` hashes three config files — **4 918 B of a
+213 231 242 B unit, 0.0023 %** — and not the DB dump or the volume tars. A planted sentinel is a drill
+technique and does not transfer; the live data drifts. **What the manifest CAN answer is
+completeness**, through the existing `unitCarriesData` (`r403_hollow.go:40`), with no new metadata.
+Filed as R-409.
+
+**Q4 — ~4 s per app, 25 s for all eight, cheaper than the weekly check.** Through the product's own
+path: docmost unit 9 s, kimai full 11 s. Raw restic, all 8 snapshots / **774 378 123 B logical** back
+to back: **25 s**, individual times 2 253–3 978 ms *regardless of size* (185 KB → 2.25 s, 213 MB →
+3.20 s). The cost is per-snapshot round-trip plus ≈ 1 s per 200 MB. Peak scratch = the app's full
+logical size, 213 272 202 B for the largest. The restic cache is **1.1 MB** (index only) and does not
+hide the cost: `--no-cache` 5 423 ms vs cached 3 198 ms, trees byte-identical. **Against R-359's
+35.0 s / 39.2 s: the same 100 % check re-measured today is 40 257 ms — so restore-testing the whole
+box costs LESS than one weekly check.** Extrapolation to 10×/100× is in the findings doc, **labelled
+as extrapolation**, with scratch space named as the constraint that binds before time does; the
+single-store hole is R-401's.
+
+**Q5 — skip-if-busy stays right, and a bigger thing is wrong.** Scheduler registrations read off the
+box (CEST): db-dump 02:30, tier2 03:30, **offbox-backup 04:15 (2m52s measured)**, abandon-sweep 05:10,
+**offsite-integrity 06:00 (40.3 s)**. A 25 s hold is seconds, not minutes, and there is an empty gap
+04:18–06:00. **But `RestoreOffboxScratch` takes no `acquireRunning` at all** — nine non-test callers,
+it is not one — while `offbox_integrity.go:28` asserts *"Every off-site operation takes
+`acquireRunning`"*. `restore_wizard.go:174` records the same fact independently. Filed as **R-408**.
+
+**Q6 — the restore itself writes nothing; the product writes anyway; and `check` writes a lock.**
+Observed with a lock sampler and an argv sampler, both inside the container, the repo URL redacted at
+source. **Positive control:** across the product's integrity run the repo went `locks=0` →
+`locks=1 id=81fd4d42…` for nine consecutive samples → `locks=0`. **The same instrument saw zero locks
+across two restores**, so `restic restore` in 0.14.0 does not lock. Observed argv for one restore:
+`snapshots latest --tag <app> --json`, then **`unlock`**, then `restore <id> --target …`. The middle
+one is `unlockStale` (`offbox_restore.go:289`), unconditional, a **delete verb**. **§5's lead was
+right in direction and wrong in mechanism** — the write is `unlockStale`, not `resticStep`'s
+escalation. **The constraint IS satisfiable:** `--no-lock` + skipping `unlockStale` writes nothing,
+and both mechanisms exist in 0.14.0 unused. `offbox_integrity.go:255`'s *"It NEVER writes to the
+repository"* is filed as **R-407**. **Neither was fixed** — §7 forbids it.
+
+**Q7 — one of five.** R-353 (a *local* restore path) **no**; R-354 (no volume-replay leg, after the
+scratch) **no**; **R-356 (refused every driveless app) YES — five of eight apps on this box would
+have fired it on the first night**; R-358 (needs a part-way failure) **no**; R-403 (destroyed a
+*local* copy) **no as filed, yes for the shape**. **The honest verdict is "few", and it points
+elsewhere:** `check` proves the stored bytes are the stored bytes, never that we stored the *right*
+thing. A hollow unit backs up, checks at 100 % and restores cleanly, and recovers nothing — R-403,
+measured in bytes nine days ago. Nothing asks that question on any tier.
+
+## 4. Recommendation
+
+Three options with costs and a do-nothing outcome are in the findings document. **I would pick option
+C — the narrow test:** one app a night, restored to scratch, checked against its own `manifest.json`,
+scratch deleted, the snapshot recorded as the proof. ~4 s and ≤ 213 MB per night; catches R-356 and
+the R-403 class; needs no new metadata. **It must use `--no-lock`, skip `unlockStale`, and take
+`acquireRunning`** — all three established by this spike. **Options A (do not build) and B (scheduled
+attended drill) were considered explicitly and are argued in the document; B is the weakest, because
+it is what already happens.** **R-87 should be RE-SCOPED, not built as written — and that is Viktor's
+call**, so the row stays open carrying the verdict, and `STATUS.md` item 4 asks it in plain words.
+
+## 5. Evidence
+
+`documentation/audits/evidence-spike-restic-restore-2026-08-31/`, 31 files, numbered by question.
+**Every file was pulled off the box before any teardown** (R-320) — including the two in-container
+sampler logs, which were `cat`ed to DooPlex before the container `/tmp` was cleared.
+
+## 6. Probes removed — all three layers, and none of them is "nothing was created"
+
+| layer | created | after teardown |
+|---|---|---|
+| PVE host `/root` | 6 scripts + one 0600 password file | `ls \| grep` → nothing |
+| guest 9201 `/root`, `/tmp` | 9 files | grep → nothing |
+| container `/tmp` | 5 files + 2 run-flags | `/tmp` lists empty; no restic process left |
+
+**Scratch directories:** the four created by this session's restores (`docmost`, `kimai`,
+`privatebin`, `opengist`) were removed. Three (`bookstack`, `calibre-web`, `paperless-ngx`) pre-date
+this session and were **left alone**. The local password copy was `shred -u`'d.
+
+**Two state changes recorded rather than hidden:** the integrity check run as the lock positive
+control **recorded its verdict** (`last_integrity_check` → `2026-08-31T13:41:28Z`, depth `structure` →
+**`100%`**, due-ness advanced 7 days), and four restores plus two logins appear in the controller log.
+**Nothing was written to the off-site repository by hand.**
+
+## 7. Register
+
+| id | action |
+|---|---|
+| **R-87** | **moved back to `OPEN-ITEMS.md`** (verbatim from `ef6ac6f^`, beside R-95), then updated with the spike verdict and a re-scope proposal |
+| **R-398** | de-tabled in `CLOSED-ITEMS.md`; the open row is the record |
+| **R-404** | bypass count corrected six → **seven** (this session's Part 1 push) |
+| **R-405** | filed + **CLOSED** — the mis-file, the reproduced count, the gate |
+| **R-406** | filed — two findings share the id R-133 |
+| **R-407** | filed — `restic check` takes a lock; the comment says it never writes |
+| **R-408** | filed — `RestoreOffboxScratch` takes no `acquireRunning` |
+| **R-409** | filed — the unit manifest hashes 0.002 % of the unit |
+
+**Register size:** `OPEN-ITEMS.md` **165 → 171** rows (+R-87 restored, +R-405..R-409); `CLOSED-ITEMS.md` **153 → 151** (−R-87, −R-398).
+Ceiling **R-404 → R-409**.
+
+`python3 scripts/unproven.py --summary`: 55 claims, walked 20 / partial 17 / built 14 / missing 4,
+**NOT WALKED 35 of 55 — unchanged by this session**, which shipped no product claim.
+
+## 7b. Golden 0.230.0 — baked, vouched, delivered (second half of the session, on request)
+
+**This was NOT part of the spike and is reported separately so the two are not confused.** Asked for
+after the spike closed; the spike itself still changed no product code.
+
+| | |
+|---|---|
+| `GOLDEN_SHA256` | `9287f7cef5f13166276e8406005e3f28004004510c5184f1c1c7377f7aafad2e`, 657 873 700 B |
+| markers | `docker OK (overlay2` 1 · `including mount point` rootfs 1 + mp0 1 · `upload OK (HTTP 201)` 1 · `excluding` 0 · `FATAL` 0 — counted on the **committed** log |
+| three readers agreed | the bake's own print, the **round trip** of the published bytes, and the hub's Day-0 dropdown reading Gitea on a different code path |
+| the artifact names its own controller | `tar --zstd -xOf golden.tar.zst ./etc/felhom-controller-image` → `felhom-controller:0.230.0`, with 19 382 entries under `var/lib/felhom/docker/` |
+| vouch | `golden_version` 0.229.0 → **0.230.0**; `agent_version` 0.130.0 and `min_agent` 0.129.0 **unchanged** — v0.230.0's `MinAgent` is 0.129.0, and 0.129.0 ≤ 0.130.0 so this is not the R-216 shape. Re-read from the page; `golden_behind_fleet` confirmed absent |
+| floor | `min_controller_version` 0.229.0 → **0.230.0**, a separate setting, done on the operator's explicit answer |
+| **the unattended proof** | `demo-felhom` was on **0.229.0 — the R-403 build** — and moved itself: `controller-swap: image file written` 16:21:30 → `controller-swap: new controller healthy` 16:21:40 CEST. Both boxes now 0.230.0, healthy |
+| pre-gates | 404 pre-gate passed; token-leak grep **0** on the committed log **and 1** on a seeded throwaway copy, so the zero is earned. Unit properties grepped for the token: **0**, positive control **1** |
+| teardown | `pct destroy 9100 --purge`, `shred -u` after the log was copied out, `poweroff`, qemu confirmed exited with `ps -eo comm` (not `pgrep -f`, which self-matches), disk back to `virgin` |
+
+Full record: `documentation/tests/golden-0.230.0-2026-08-31/README.md`.
+
+**One honest gap vs. the 0.229.0 precedent:** the bake script's sha256 was **not** compared across
+the hop, only recorded on DooPlex (`7b0fb5cf…73b6a1`). A corrupted `scp` would have failed the bake
+rather than produced a wrong golden — but that is an argument, not a measurement.
+
+**And the gate that flagged all this has a hole, found while it went green:** `golden_currency_gate.py`
+matches a **directory name** (`scripts/golden_currency_gate.py:89,123`). I created
+`documentation/tests/golden-0.230.0-2026-08-31/` before the bake finished, and the gate would have
+passed at that moment. Filed as **R-410**.
+
+## 8. Controller code, and the golden debt as it now stands
+
+**The spike changed no controller code**, and that remains true — the golden bake ships the image
+that was already released as v0.230.0, unchanged.
+
+## 8. No controller code changed and no golden is owed
+
+`felhom-controller` and `felhom-agent` were **read only** for the spike. No version bump, no build,
+no deploy. **The golden debt — v0.230.0 released with the newest bake at 0.229.0 — was already red at
+`dddcc80` before this session started** and belonged to that release, not to the spike;
+`golden_currency_gate.py` was the only failing gate throughout the spike. **It was then PAID on
+request** (§7b): the gate now exits 0, and the two register-only pushes below were the last that
+needed a bypass.
+
+**`git push --no-verify` was used, twice, for exactly that reason** — records-only pushes meeting the
+golden gate. That is R-404's subject and the count is updated in its row.
+
+**CI is RED for both of this session's pushes, and I checked rather than assumed.** Pulled by run id
+from `gitea.dooplex.hu/api/v1/repos/admin/felhom.eu/actions/tasks`:
+
+| run id | run_number | head_sha | status |
+|---|---|---|---|
+| 451 | 280 | `66156c619f` | success |
+| **456** | **281** | **`dddcc808be`** | **failure — the commit this session STARTED from** |
+| **458** | **282** | **`6e550aedd3`** | **failure — this session's Part 1** |
+| **459** | **283** | **`130f7a6eba`** | **failure — this session's spike commit** |
+| **460** | **284** | **`32a4c35c9c`** | **failure — the CI-verdict amendment** |
+| **461** | **285** | **`2263245cf2`** | **SUCCESS — the golden bake commit** |
+
+CI runs the same `repo_gates.py` entry point, so it fails on `golden_currency_gate.py` exactly as the
+pre-push hook did. **Run 281 is the proof that it is not mine:** it is the previous session's commit,
+pushed before this session began, and it is already red. Nothing else in the suite fails at any of the
+three commits. **It resolved exactly there: run 285, the golden-bake commit, is GREEN** — the first green run since
+`66156c619f`, and the first push this session that the pre-push hook let through unbypassed
+(`pre-push [felhom.eu]: gates OK - push proceeding`). All 13 gates pass.
+
+## 9. Observations — noticed, not acted on
+
+- `paperless-ngx` has an off-site snapshot under that tag and none under `paperless`; `filebrowser`
+  has none at all (it is infrastructure, so that may be correct). Not chased.
+- `CLOSED-ITEMS.md` rows **R-399** and **R-400** supply two columns where the table declares four —
+  they render with no `Shipped` and no `Evidence`. The new gate warns rather than convicts, because an
+  empty state cell is not an open state word.
+- Two rows (**R-309**, **R-351**) carry a `|` inside their body, shifting their own cells. Named as
+  the gate's first residual hole.
+- The controller image has **no `ps` and no `python3`**. `/proc/*/cmdline` is the substitute that
+  works, and it is worth knowing before writing any probe that runs in there.
+- The guest scheduler logs in **CEST**, not UTC — `offbox-backup scheduled for 2026-09-01 04:15 CEST`
+  against a `last_run` of `02:17:57Z`. Consistent, and the opposite of what the project memory says
+  about guest time.

+# REPORT — SPIKE R-95: can the box be stopped from deleting its own off-site history? (2026-09-01)
+
+## Q1 first, and it raises the urgency rather than lowering it
+
+**The safety net cannot be seen from the box, on either machine, so the seven-day bound is
+unverified — and unverifiable from the product side.**
+
+Measured over each box's own SFTP credential, read-only, with controls that passed first:
+
+| probe | demo-hp (sub-account A) | demo-felhom |
+|---|---|---|
+| positive control — account home | lists `.ssh`, `<repo>` | lists `.ssh`, `<repo>`, `<repo>.orphaned-20260810` |
+| negative control — bogus name | `not found` | `not found` |
+| `./.snapshots` | **`not found`** | **`not found`** |
+| `<repo>/.snapshots` | `not found` | `not found` |
+| `/` | `Permission denied` (jailed) | same |
+
+**Either no snapshots exist, or a sub-account cannot see them. The box cannot tell which, and neither
+is a reprieve** — a snapshot the box cannot see is one it cannot restore from, so recovery is an
+operator act at the Hetzner panel, not a product capability.
+
+**The register's claim rests on nothing that was ever checked.** `OPEN-ITEMS.md:233` is a row with
+**no R-number**, its "confirm tomorrow" was **2026-07-27** (36 days), and the `DUE-CHECKS` block built
+for exactly this (R-341) is **empty**. R-95's own text says "Mitigation now ARMED"; that word is
+**withdrawn** pending R-429.
+
+**The task expected Q1 might bound the exposure to seven days. It does not.** I stopped at the §11-D
+fence rather than answering it with the provider token.
+
+## Q1–Q7, one answer each
+
+| Q | answer |
+|---|---|
+| **Q1** | **NO / unknowable from the box.** Measured on both machines with controls. → R-429 |
+| **Q2** | **Ten verbs, not nine, and TWO `forget --prune` sites.** `check` (`offbox_integrity.go:316`) is missing from the task's list; `dump` is not a verb (`offbox_progress.go:185` is a phase constant) — withdrawn. Delete-capable: `forget`/`prune` (`offbox.go:1388` **and `:1759`**), `unlock` (`:746`, `:768`). |
+| **Q3** | **No. DOCUMENTED** from `hub/internal/hetznerapi/hetznerapi.go:38-45`: `AccessSettings` has five booleans and **`readonly` is the only permission axis**. No append-only. Corroborated by existing state, no new action: demo-felhom's home holds a `<repo>.orphaned-20260810` directory produced by a controller **rename**, which is delete-class. |
+| **Q4** | **The PBS shape does not transfer.** PBS is a server that can refuse; a Storage Box is a filesystem that **runs nothing**, so there is no far end to move retention to. Four candidates costed; each concentrates a delete-capable credential. **R-191's trap is doubled here** — both `forget` sites must be disarmed in the same change or every successful backup reports failure. |
+| **Q5** | **NOT the blocker — measured.** Under a faithful append-only model (both controls passed), a stale lock does **not** wedge the store: `backup`, `check`, `snapshots --no-lock` and `restore --no-lock` all succeeded. **But `unlock --remove-all` printed `successfully removed locks` while the lock survived** → R-430. The crash-lock (foreign hostname) window is **UNKNOWN**. |
+| **Q6** | **Reachable. MEASURED:** `rest:` gives a connection error where the control `banana:` gives `invalid backend` — **restic 0.14.0 speaks REST**. Append-only is a **rest-server** flag; `restic help` contains zero occurrences of "append". Needs a machine in the recovery path (**ep0 is protected — architecture change**) and either a mount in the hot path or moving every customer's history. |
+| **Q7** | **Nearly free. MEASURED:** `snapshot_count` already reaches the hub (`report/types.go:131` → `backup_card.go:118`) and **the hub APPENDS reports** (`store.go:968` INSERT; read is `ORDER BY id DESC LIMIT 1`), so the history to compare against is already on disk. No box change, no credential, no new service. |
+
+## The four options, ranked
+
+**My pick: answer Q1 today (Viktor, ten minutes) → build 4 → then 2. Defer 3.**
+
+1. **Do nothing — not acceptable as it stands.** It used to mean "bounded to seven days". Q1 shows
+   that sentence is unsupported. £0, no evenings, and an unbounded exposure on the tier holding the
+   customer's documents.
+2. **Copy the PBS shape — worth doing, smaller than it sounds.** Q5 removed the fear that it would
+   wedge the store. But Q3 means the credential still *can* delete; the box would merely stop using
+   it. That is discipline, not a guarantee, and a compromised guest is unaffected. One evening + a new
+   home for retention.
+3. **Change the transport — the only real prevention, and not yet.** Q6 says it is reachable. It costs
+   an always-on service in the recovery path and a protected machine's architecture. Choosing it
+   before Q1 is answered is the wrong order.
+4. **Detect instead of prevent — cheapest by a wide margin, do this first.** Q7 measured that the
+   material already exists. Converts "we would never know" into "we know tomorrow". Third instance
+   this week of *proving beats preventing when preventing is expensive*.
+
+## What I could not measure, and what would settle it
+
+| unknown | what would settle it |
+|---|---|

+## Register
+
+**Before:** OPEN 179 · CLOSED 161. **After:** OPEN 181 · CLOSED 161.
+**Filed R-429** (the unconfirmed snapshot mitigation, and the id-less row), **R-430** (`unlock` lies
+about success). **R-95 updated** with the verdict and kept OPEN; its word "ARMED" withdrawn.
+**Docs:** `07` §8 row 10 and §10.2 gained the verdict (**row 10's status deliberately NOT moved**);
+§11-D records that the fence was reached again and held; `STATUS.md` carries one plain-language item.
+
+## Compliance
+
+- **No code changed. No version bumped. No image built. No golden owed.** `golden_currency_gate.py`
+  exits 0; golden and floor remain **0.232.0**.
+- **No delete verb was issued against any live store** — no `forget`, `prune`, `unlock` or `init`.
+  Every live-store interaction was an SFTP `ls`.
+- **`ep0`, DooPlex and Peti's box were not touched at all**, not even read — the two demo boxes were
+  the only machines used.
+- **The Hetzner API and control panel were not called.**
+- **Scratch resources:** a throwaway local restic repo under `/tmp/r95s` (and `/tmp/r95scratch` in the
+  first attempt) inside the controller container on demo-hp, 60 MB, plus three probe scripts. **All
+  removed**, verified by the scripts' own teardown output (`scratch: gone`). Nothing was created on
+  any Storage Box.
+
+## Observations, and my own mistakes by name
+
+1. **The register calls a mitigation ARMED that has never been confirmed, in a row that cannot be
+   cited because it has no id, with the dated-check mechanism sitting empty beside it.**
+   **FILED: R-429.**
+2. **`restic unlock --remove-all` reports success on a deletion that did not happen**, and the
+   crash-lock self-heal is built on it. **FILED: R-430.**
+3. **The task's own verb list was missing `check` and included `dump`, which is not a verb**, and it
+   names one `forget --prune` site where there are two. **NOT-A-FINDING: the brief invited me to
+   confirm the list myself, which is what this is; both corrections are in the spike document and the
+   second one is carried into R-95's row, because disarming one site and not the other reproduces
+   R-191 exactly.**
+4. **My mistake — my first Q5 model proved nothing.** I used `chmod a-w` and ran restic as **root**,
+   which ignores permission bits, so every verb succeeded and I nearly recorded "no wedge" on a test
+   that tested nothing. Rebuilt as a sticky directory with a root-owned lock and restic run as
+   `nobody`, with two controls. **NOT-A-FINDING: caught inside the same session by the result being
+   too clean; the corrected model is the one reported, and the first is described so nobody repeats
+   it.**
+5. **My mistake — my first `sftp` probe used `-p` for the port**, which `sftp` reads as "preserve", so
+   the port became the destination and all three probes returned identical usage errors. **The
+   controls are what exposed it** — a positive and a negative control failing the same way is an
+   instrument fault, not a result. **NOT-A-FINDING: a flag error of mine, corrected in one command;
+   it is recorded because the failure mode it demonstrates — three identical errors reading as three
+   findings — is the one this project keeps paying for.**
+6. **My mistake — I wrote the §8 verdict onto row 4 instead of row 10.** The anchor text I matched
+   appears in both rows and I replaced the first occurrence. Caught by checking the line number,
+   reverted from row 4 and applied to row 10, both verified by grep. **NOT-A-FINDING: an editing error
+   of mine, corrected within the session and verified in both directions, so no wrong claim ever
+   reached a push.**
+7. **My mistake — I put two escaped pipes inside a register row**, which makes it a five-column row in
+   a three-column table and would have made it unreadable to `closed_register_gate.py` — **the exact
+   defect I fixed in that gate yesterday.** Caught by counting pipes before committing. **NOT-A-FINDING:
+   corrected before the push; recorded because I introduced the same shape twice in two days.**
+8. **The task's baseline table lists `felhom-agent` at `058b945`; it is at `4586f0f`.**
+   **NOT-A-FINDING: that is my own push from the previous session, so the table was stale rather than
+   wrong about anything that matters here; the agent repo was not touched by this spike at all.**

+# REPORT — dated checks that bite, the floor raise on the record, the snapshot that covers less (2026-08-18)
+
+**Three pieces of bookkeeping, no machine put at risk. The hub was READ ONLY throughout.**
+
+**The headline is that Part 3's premise was wrong.** The floor raise was *not* a no-op: it moved a
+live customer box nine seconds after the save. That is the whole reason the task said to read it back
+rather than assume it. **R-343 is therefore filed OPEN, not CLOSED**, per the task's own condition.
+
+---
+
+## 1. Confirmed baselines
+
+| item | value |
+|---|---|
+| felhom.eu `main` @ start | `f267bc047f198de4cb600068fdd8bcef557cff20` — matches the sheet |
+| clean tree at start | yes; `HEAD == origin/main` in felhom.eu, felhom-controller, felhom-agent |
+| `scripts/` version IN | `felhom-host-install.sh v1.28.0` (CHANGELOG head) |
+| `scripts/` version OUT | `due_checks_gate.py v1.0.0` (new head entry) |
+
+## 2. Files created / modified
+
+**Created:** `scripts/due_checks_gate.py`, `scripts/test_due_checks_gate.py`,
+`REPORT-register-and-floor.md`.
+**Modified:** `scripts/repo_gates.py` (registration + docstring), `scripts/CHANGELOG.md`, `CLAUDE.md`,
+`CONTEXT.md`, `STATUS.md`, `documentation/backlog/OPEN-ITEMS.md` (block + R-342 + R-343),
+`documentation/runbooks/publish-train-rules.md`.
+Commit hashes are in §9.
+
+## 3. Tests — 37 assertions, and a red-proof that caught my own test
+
+`python3 scripts/test_due_checks_gate.py` → **passed: 37, failed: 0**, groups A–G.
+
+### Red-proof 1 — the boundary. **It failed usefully: it exposed a HOLLOW assertion of mine.**
+
+**Mutation:** `due_now = [... if r[1] <= today]` → `< today`.
+**First run, before the fix:** Group C reported
+
+```
+  PASS  C: due TODAY exits 1  rc=1          <-- passed, and should NOT have
+  FAIL  C: says DUE TODAY rather than overdue
+```
+
+**The `rc == 1` assertion passed for the wrong reason.** With `<`, a row dated exactly today falls
+into neither `due_now` (`<`) nor `pending` (`>`), so `min(pending, …)` raised
+`ValueError: min() iterable argument is empty` and the **traceback** exited 1. Confirmed directly:
+
+```
+  File ".../due_checks_gate.py", line 232, in main
+    nearest = min(pending, key=lambda r: r[1])
+ValueError: min() iterable argument is empty
+RC=1
+```
+
+**An exit code alone cannot distinguish a verdict from a crash.** Two fixes, both kept:
+
+1. the test now asserts `DUE-CHECKS GATE FAILED` is in the output **and** `Traceback` is not, plus a
+   new `test_c_gate_never_ends_in_a_traceback` across overdue/future/empty inputs;
+2. the gate returns **2 (INCONCLUSIVE)** with a message if the partition is ever broken again,
+   because a crash is never a verdict.
+
+**Re-run after the fix — the mutation now bites properly:**
+
+```
+  FAIL  C: due TODAY exits 1 (boundary is <=)  rc=2
+  FAIL  C: exits 1 as a VERDICT, not a traceback
+  PASS  C: did not crash
+  FAIL  C: says DUE TODAY rather than overdue
+passed: 34   failed: 3
+```
+
+**Mutation reverted**, verified by `grep -n "MUTATED"` returning nothing and the `<=` line restored.
+
+### Red-proof 2 — the missing-block path
+
+**Mutation:** the missing-block branch `sys.exit(2)` → `sys.exit(0)`.
+**Seen failing:**
+
+```
+  FAIL  E: missing block exits 2 (NOT 0)  rc=0
+passed: 36   failed: 1
+```
+
+**Reverted**, `sys.exit(2)` restored on that branch.
+
+## 4. The gate's real output in all three states
+
+**Overdue (fixture, today=2026-08-20):**
+
+```
+DUE-CHECKS GATE FAILED: 1 dated check(s) are due or overdue as of 2026-08-20 (UTC).
+
+  R-341    due 2026-08-19   1 day(s) OVERDUE
+           measure: ep0 proxy fd count + ESTAB/CLOSE-WAIT split; PID must still be 551655
+           the command and its preconditions are in the R-341 row of documentation/backlog/OPEN-ITEMS.md
+
+Take the measurement, record the result in that R-row, then remove the row from the
+DUE-CHECKS block. Moving the date instead is allowed — state the reason in the R-row.
+NOTE: this gate fires on a PUSH, not on the date; it may be later than the date.
+```
+
+**Pending / the LIVE run against the real register today (these are the same run):**
+
+```
+due-checks gate OK — 2 dated check(s) pending, none due yet.
+  today (UTC): 2026-08-18
+  nearest: R-341 due 2026-08-19 (in 1 day(s)) — ep0 proxy fd count + ESTAB/CLOSE-WAIT split; PID must still be 551655
+  (fires on the next PUSH after a date passes, not on the date itself — by design)
+```
+
+## 5. The runner's output
+
+```
+  site               OK            (exit 0)
+  hostinstall        OK            (exit 0)
+  hub-confirm        OK            (exit 0)
+  manifest-bearer    OK            (exit 0)
+  reuse-refs         OK            (exit 0)
+  instructions       OK            (exit 0)
+  golden-currency    OK            (exit 0)
+  wire-contract      OK            (exit 0)
+  hub-copy           OK            (exit 0)
+  due-checks         OK            (exit 0)
+all felhom.eu gates OK
+```
+
+Group G asserts registration by **running the runner** and matching `due-checks` in its output, never
+by grepping `repo_gates.py`'s source — a commented-out entry still contains the string.
+
+## 6. Part 3's five reads — evidence, not summary
+
+### READ 1 — the live floor, from the store
+
+```
+  artifact_agent_version     = '0.129.0'    (updated 2026-08-18 11:00:59)
+  artifact_golden_version    = '0.216.0'    (updated 2026-08-18 11:00:59)
+  artifact_min_agent         = '0.129.0'    (updated 2026-08-18 11:01:00)
+  min_controller_version     = '0.216.0'    (updated 2026-08-18 12:36:58)
+```
+
+**The raise landed**, so Part 3 proceeded. Read from `hub_settings`, not the form.
+
+### READ 2 — per-customer overrides
+
+```
+  demo-felhom      status=active     override=''         config_version=12
+  demo-hp          status=active     override=''         config_version=5
+  drill-r50        status=blocked    override=''         config_version=1
+  peti-felhom      status=active     override=''         config_version=6
+  tester-1         status=active     override=''         config_version=1
+  -> 0 customer(s) carry a non-empty override
+```
+
+**Zero overrides**, so the global applies to everyone and no box hides behind a lower one.
+
+### READ 3 — every box's controller version. **Two are below the floor.**
+
+```
+  demo-felhom      controller='0.216.0'    last_report=2026-08-18 13:07:07
+  demo-hp          controller='0.216.0'    last_report=2026-08-18 13:01:34
+  drill-r50        controller='0.213.0'    last_report=2026-08-12 15:33:25
+  peti-felhom      controller='0.115.0'    last_report=2026-07-15 08:39:00
+```
+
+**The two REPORTING boxes are both at 0.216.0, at the floor.** The other two are below it and neither
+is a reporting box: `drill-r50` is `status=blocked`, last heard from six days ago, powered off and
+reverted; `peti-felhom`'s host row was deleted on 2026-07-15. Reported here rather than as a
+footnote, per the task's edge-case rule.
+
+*(Note: `guests.controller_version` is empty for every guest — the hub carries the controller version
+on `reports.controller_version`, not on the guest row. The first query I wrote read the guest field
+and would have reported "unknown" for every box.)*
+
+### READ 4 — directives and holds
+
+```
+2026/08/18 14:36:58 [INFO] Global controller-version floor set to "0.216.0"
+```
+
+**No `managed floor HELD` line exists** — searched over 24 h of pod logs. (Hub log lines are CEST;
+the DB stores UTC, hence 14:36:58 here and 12:36:58 above — the same instant.)
+
+### READ 5 — **THE FINDING: a controller DID auto-update after the raise**
+
+```
+2026-08-18 12:37:07 | demo-felhom | controller_updated | Controller frissítve: 0.214.0 → 0.216.0
+2026-08-18 12:37:12 | demo-felhom | controller_started | Controller elindult (0.216.0)
+```
+
+and the version trail confirms it:
+
+```
+   2026-08-18 11:14:55  controller=0.214.0
+   2026-08-18 12:37:12  controller=0.216.0
+```
+
+**`demo-felhom` had been on 0.214.0 since 2026-08-12 16:44 and the floor raise pulled it to 0.216.0
+nine seconds after the save** — exactly the "acts immediately on the next report cycle" that
+`publish-train-rules.md` rule 2 documents and that the 2026-07-11 incident was filed for.
+`demo-hp` was already on 0.216.0 (hand-deployed 2026-08-14 08:31) and did not move.
+
+**No error, warning or critical event followed** — the update completed and the controller restarted.
+So: harmless in outcome, but **not a no-op**. "Every reporting box is at or above the floor" is true
+**because of** the raise, not independently of it.
+
+**R-343 is filed OPEN.** The task's closing condition was *all five reads clean and no directive
+served*; read 5 shows a live box moved. It went well, and a record that called it inert would mislead
+the next reader.
+
+## 7. `peti-felhom` — not contacted
+
+**The machine was not contacted in any way.** Sourced from the PETI register row, quoted:
+
+> *"a report from a deleted host 401s and is not persisted"*
+
+with its host row deleted `2026-07-15 08:56:22` (`host_deletions` id=1). It therefore cannot receive a
+floor directive and the raise cannot reach it. Its `reports` row still shows controller 0.115.0 from
+its last report on 2026-07-15 08:39:00 — a stale record, not a live box.
+
+## 8. The two `build-felhom-iso.sh` facts, confirmed in the script
+
+**(a) It is a BUILD-TIME gate.** `assert_golden_ge_floor()` is defined at **`:77`** and called at
+**`:267`**, in the build flow.
+
+**(b) It FAILS OPEN with a warning when its inputs are absent** — `:78-82`:
+
+```bash
+    local golden="${FELHOM_ASSERT_GOLDEN:-}" floor="${FELHOM_ASSERT_FLOOR:-}"
+    if [[ -z "$golden" || -z "$floor" ]]; then
+        log_warn "R-71 golden>=floor gate UNENFORCED — pass FELHOM_ASSERT_GOLDEN + FELHOM_ASSERT_FLOOR to enforce (golden='${golden:-unset}' floor='${floor:-unset}')"
+        return 0
+    fi
+```
+
+Both read as the task described. **No ISO rebuild is required:** the golden is fetched at first boot
+from the hub's manifest (0.216.0 — at the floor, not below it), and this gate governs *future* builds.
+
+
+## 9. Commits and CI
+
+| commit | contents |
+|---|---|
+| `0a5e9b14dc84ecfb179b2654d079c2f6d3f15fe2` | the gate, its tests, registration, both register rows, the block, and all §5 documentation |
+
+**CI run `355`, `head_sha 0a5e9b14d`, conclusion `success`** (started 2026-08-18T13:17:04Z). The
+previous run `354` on `f267bc047` was also green, so this run's green is attributable to this change
+rather than inherited from a red baseline — and per §13 of the task, a red run here would have been
+mine to own.
+
+**The push needed no `--no-verify`.** The pre-push hook ran `repo_gates.py --fast`, including the new
+`due-checks` gate, and passed — so the gate has now run in its real place, in both homes, not only in
+its own test suite.
+
+## 10. NOT yet validated
+
+**The gate has never fired on a real overdue date in the live register.** Every conviction shown here
+is from a temp-file fixture or a `FELHOM_GATE_TODAY` override. Its first genuine firing will be the
+next push on or after **2026-08-19**, when R-341's first check comes due. Until that happens, "it
+refuses the push" is proven in fixtures and *inferred* in production — the registration test proves it
+is wired into the runner, which is the part that could silently not be true.
+
+Also unvalidated: the block's own upkeep. Nothing checks that a row removed from the block was removed
+because the measurement was *taken* rather than because it was inconvenient.
+
+## 11. Teardown
+
+**This task provisioned nothing.** No VM, no container, no machine touched. The hub was read-only —
+snapshots of `hub.db` + `-wal` were taken into the session scratchpad for querying and are not
+committed.
+
+## 12. Register rows
+
+**The block, verbatim as committed:**
+
+```markdown
+<!-- DUE-CHECKS-BEGIN — machine-readable. Parsed by scripts/due_checks_gate.py.
+     One row per dated check. The R-number must have a row above. Dates are UTC.
+     Clearing a row means the check was DONE and its result recorded in that R-row —
+     or the date was deliberately moved, with the reason stated in the R-row.
+     This block is an INDEX, not the detail: the command and the preconditions live in
+     the R-row. Duplicating them here would create the second source this design avoids. -->
+| item | due (UTC) | what to measure |
+|---|---|---|
+| R-341 | 2026-08-19 | ep0 proxy fd count + ESTAB/CLOSE-WAIT split; PID must still be 551655 |
+| R-341 | 2026-08-25 | same, +7 d |
+<!-- DUE-CHECKS-END -->
+```
+
+**R-341's dates in the register matched the sheet exactly** — no disagreement to report.
+
+**R-343's verdict cell, verbatim:**
+
+> **OPEN — NEW 2026-08-18.** Deliberately NOT closed: the task's closing condition was *all five reads
+> clean, no directive served*, and read 5 shows a live box updated. It went cleanly and is the floor
+> working as designed — but a change recorded as a no-op when it moved a customer box is exactly the
+> kind of record that misleads later
+
+**R-342** filed **READY (S)**, owner *Viktor decides; CC executes*, quoting `stop2-snapshot.txt`
+verbatim on what the snapshot covers and does not.
+
+## 13. `unproven.py --summary`
+
+```
+where felhom stands — 55 claims, verified_on 2026-08-09
+  walked   23
+  partial  14   (6 cite evidence, 8 prose only)
+  built    14   (0 cite evidence, 14 prose only)
+  missing  4   (0 cite evidence, 4 prose only)
+  NOT WALKED: 32 of 55
+```
+
+**No number moved**, correctly: this task added a gate and three register facts, and walked no claim
+in the standing picture.
+
+## 14. Observations — noticed, deliberately not acted on
+
+- **`CLAUDE.md`'s gate list named only 6 of the 10 registered gates.** It was missing
+  `golden_currency_gate.py`, `wire_contract_gate.py` and `hub_copy_gate.py` — all registered weeks
+  ago. I completed the list rather than appending a 7th name to a list that was already wrong, since
+  the section's stated job is to name each gate. Effective line count 124 → 128 against a ceiling of
+  200, so no trim was needed.
+- **`documentation/architecture/00-capability-map.md` — no change, and this is the explicit
+  statement the task asked for.** No row's evidence citation names the floor or golden *version*:
+  line 153's publish-train row cites a runbook path, and line 44's golden literal is a dated
+  historical citation on the recovery-journey row.
+- **`drill-r50` will be dragged 0.213.0 → 0.216.0 by this floor if it is ever booted and reports.**
+  Its agent (0.129.0) meets `MinAgent`, so the floor would be served, not held. That is the floor
+  doing its job; noted so it is not read as a surprise later.
+- **The hub's log timestamps are CEST while its DB stores UTC.** Not a defect, but it makes a log
+  line and an events row for the same instant look two hours apart, which is worth knowing before
+  correlating them under pressure.
+- **`min_controller_version` and `artifact_*` live in the same `hub_settings` table but are saved by
+  different actions**, two hours apart today (11:00:59 vouch, 12:36:58 floor). That separation is
+  rule 2 working, and is why reading only one of them would give a misleading picture.

+
+---
+
+## ⛔ The decision waiting on you
+
+Phase C wants one overnight window on `demo-hp`. **The measurement found something that changes which
+mutation is worth running**, so there are two versions of it. Both are one mutation on a Tier-0
+disposable box, both arm a dead-man timer first, both are unattended.
+
+| | **Option A — stop `pvestatd`** (what the spike prompt specifies) | **Option B — stop `felhom-agent`** (what the evidence now points at) |
+|---|---|---|
+| what it tests | the original Q3: does the leak track the request rate? | does the leak track **our agent's** cycle? |
+| predicted result | **null** — leak unchanged at ~201.6/day, ~84 descriptors in 10 h, split evenly ~42/~42 | leak **halves** — ~101/day, ~42 descriptors in 10 h, split ~42 from `demo-felhom` and **~0** from `demo-hp` |
+| what it buys | **falsification.** If the leak *did* halve, the whole Part-1/2 attribution is wrong and must be withdrawn | **confirmation by a second, independent route.** A near-zero contribution from the quietened box is decisive |
+| cost if the attribution is right | a confirmed null — real evidence, but no new information beyond what Parts 1–2 already show | the sharpest possible confirmation |
+| risk | none beyond the window: `pvestatd` is PVE's stats daemon; the box keeps running, backups are not due until ~08-25 | slightly higher: the agent is our own product on the box. It would stop reporting to the hub for the window, and the hub's staleness watch may notice |
+
+**I would run Option A, tonight.** Two reasons. It is the mutation the prompt authorises, and standing
+rule 2 says exactly one mutation exists in this run — substituting one is my call to propose, not to

+
+## What I did, and what it found
+
+### Part 0 — the dated-check gate's first real conviction, captured before anything else
+
+The 2026-08-19 row was one day overdue. Every conviction this gate had produced before came from a
+fixture or a `FELHOM_GATE_TODAY` override; **this is its first firing on a real overdue date in the live
+register**, and it behaved correctly:
+
+- **exit code 1** — a verdict, not a crash (2) and not a pass (0);
+- the message **names R-341 and the days overdue** (`R-341  due 2026-08-19  1 day(s) OVERDUE`), so the
+  exit code is not doing the work alone — which is the failure mode this gate's own red-proof fell into
+  on 18 August;
+- inside `repo_gates.py` it is the **only** conviction: 9 gates OK, `CONVICTED: due-checks`.
+
+Captured verbatim in `part0-due-checks-gate.txt` and `part0-repo-gates.txt`. The row was **not** cleared
+to make the push work — it was cleared at Part 4, after the measurement existed and its result was
+recorded in R-341, which is the sanctioned order.
+
+### Q0 — R-341's first dated check: the slope is UNCHANGED
+
+Precondition passed: PID still **551655**, `NRestarts=0`, so the elapsed window is valid.
+
+**fd 17 → 405 over 166,251 s (46.18 h) = 201.6 fd/day**, Poisson 2σ 181.2–222.1.
+The prediction was pre-registered before the reading: **370–450**. **Observed 388.**
+Verdict: **unchanged**, the expected result, and not a failed upgrade.
+
+This settles the check on a window **88× longer** and a descriptor count **97× larger** than the
+30-minute windows the original answer rested on. Uncertainty drops from roughly ±50% to ±5%.
+
+**Composition:** ESTAB 0 → 388, and **CLOSE-WAIT is 0 — absent from the histogram entirely.** The
+incident document's original emphasis on `CLOSE-WAIT` is not merely the minority story; on this proxy
+generation that state does not occur at all.
+
+Runway to the 65536 ceiling: **~323 days (~2027-07-09)**.
+
+### Q1 — who is at the far end: exactly the two demo boxes, 194 each
+
+No third peer. Outcome (c) excluded. The identity is read from the API token name on every access-log
+line, not inferred from the address. `lsof` confirms the leak is sockets and nothing else: 390 of 405
+descriptors are TCP.
+
+**Persistence (31-minute diff of full 4-tuples): 388 in both readings, 0 closed, 4 new.** Not one socket
+closed. All carry keepalive timers with `retrans=0` — the far ends are answering, so these are not
+half-open sockets.
+
+### Q2 — outcome **(a)**, confirmed twice, exactly
+
+| instant | ep0 | `demo-felhom` | `demo-hp` | sum |
+|---|---|---|---|---|
+| 08:02:39 / 08:04:37Z | **388** | 194 | 194 | **388** |
+| 08:33:42 / 08:34:01Z | **392** | 196 | 196 | **392** |
+
+And the four sockets that appeared between the readings carry **the same four source ports** on ep0 and
+on the boxes. Both sides hold every connection.
+
+### The finding nobody predicted: the leak is ours
+
+`ss -tnp` on the boxes names the owner of **194 of 194** on each: **`felhom-agent`**, one PID per box.
+Zero are held by `pvestatd`. Zero by `proxmox-backup-client`.
+
+ep0's access log says the same thing by a completely independent route:
+
+| who | requests in the window | descriptors leaked |
+|---|---|---|
+| `libwww-perl` (pvestatd) | 81,192 | **0** |
+| `proxmox-backup-client` | 80,061 | **0** |
+| `Go-http-client` (**our agent**) | 811 (of which **387** `/snapshots` calls) | **388** |
+
+**One leaked socket per agent `/snapshots` call, within one.** 99.5% of the traffic produces 0% of the
+leak.
+
+**Mechanism, named from source** — `felhom-agent/internal/pbs/client.go:56-60` builds
+`&http.Transport{TLSClientConfig: tlsCfg}` as a composite literal, so `IdleConnTimeout` is the zero value
+(= no limit; `http.DefaultTransport` sets 90 s and a literal does not inherit it), and
+`cmd/felhom-agent/main.go:1486` builds **a fresh client every cycle**, as its own doc comment states.
+`CloseIdleConnections`, `IdleConnTimeout` and `MaxIdleConns` appear **nowhere in the agent repo**.
+Cadences reconcile without fitting: 900 s hub poll (184.7 cycles) + 6 h verify cadence (7.7) = 192.4
+predicted against **194 observed per box**.
+
+**No fix is proposed** — the spike-first gate forbids it, and the spec is a separate task. Filed as
+**R-344**, with the open design questions listed rather than pre-answered.
+
+### Control window: clean
+
+No reboots (ep0 up 17 d, boxes up 10 d), no daemon restarts (`NRestarts=0`), no agent restarts, **no
+request-rate gap** (3,536–3,553 per hour, every hour), **no HTTP errors at all** (every response 200
+except 8 expected 101s), no tunnel flap. **No backup ran inside the window** — the last offsite protocol
+upgrades were 08-18 03:57/03:58Z, *before* `t0`, and the tier is weekly with the next run due ~08-25, so
+**tonight's window is also clear of one.** Routine verify jobs and restore-test reads did occur; they are
+1.2% of traffic and are already counted inside the 194/box reconciliation.
+
+**Hub:** no `*_unreachable` or `*_recovered` event; the PBS-DR gauge refreshes on schedule and host
+reports land from both boxes. **Honest limit:** the hub pod is 39 h old, so hub-side logs cover 36.6 of
+the window's 46.2 hours; the first 9.6 h rests on ep0's own evidence.
+
+---
+
+## Register changes
+
+- **R-341** — first check recorded (taken at **+46.2 h, not +24 h**; the delay was pure elapsed time and
+  the longer window is stated as a **better** measurement, not a degraded one). **2026-08-19 row removed**
+  from `DUE-CHECKS`; 2026-08-25 kept, with the Phase-C perturbation quantified against it (**~3%** shift
+  on the 7-day slope even under the hypothesis we expect to be false — the reading stays usable).
+- **R-336** — mechanism named; **premise corrected and re-ranked**. Its recorded next step would have
+  produced a null result and read as a failed fix. The poll rate is now a scaling/cost item; the leak fix
+  is R-344. **Q3's proportionality verdict is explicitly NOT recorded** — Phase C has not run.
+- **R-340** — noted which of its wanted observations this run already produced, so the health-op task
+  reuses them rather than measuring a protected machine a third time. Only the loopback probe is still
+  owed.
+- **R-344 (new)** — the agent's per-cycle transport leak. READY (S).
+- **R-345 (new)** — `hub/Makefile` lines 21–22 tag and push `:latest`, which two rule files forbid.
+  READY (XS).
+- **R-346 (new)** — `ActiveEnterTimestamp` reads 5 h 56 m early for this proxy generation (the upgrade
+  re-exec'd rather than restarted, so `NRestarts` is still 0). Anchoring a slope on it gives ~12% low.
+  READY (XS).
+
+## Deliverables
+
+- `documentation/audits/SPIKE-ep0-established-connections-2026-08-20.md` — the findings.
+- `documentation/audits/evidence-ep0-established-connections-2026-08-20/` — 11 raw evidence files,
+  including the **pre-registered Phase C prediction**, committed before the mutation exists.
+- `documentation/backlog/OPEN-ITEMS.md`, `STATUS.md` — as above.
+
+## CI, checked by run ID
+
+**id `360` / run_number `237`, `head_sha 19672e685`, conclusion `success`**, started 2026-08-20 08:41:50Z
+— this run's own push. The four runs before it (ids 356–359) are also `success`, so the "green since run
+356" baseline in the spike prompt holds and nothing was inherited red.
+
+*Numbering note:* the API exposes two numbers per run and they differ by 123 here. The prompt's "run 356"
+matches the **`id`**, not the `run_number`; both are recorded in `evidence-…/ci-run-by-id.txt` so the
+reference is unambiguous.
+
+The pre-push hook ran `repo_gates.py --fast` and reported **all 10 gates OK** before the push proceeded —
+including `due-checks`, which convicted at Part 0 and passes now that the row is properly cleared. **No
+`--no-verify` was used**, and none was needed.
+
+## What is inconclusive
+
+**Q3 is unmeasured**, by design. Everything stated about proportionality is a labelled prediction. Also
+unexplained: why the two boxes' leaked counts are *exactly* equal at two separate instants rather than
+merely close. And whether restore-test reader connections leak too was not separated out (≤2% of the
+total, inside the noise).

+## Claims in the task that turned out wrong, named first
 
-## 1. The spike's answer, first and in plain language
+1. **"the GRUB menu has one entry"** — the **release** image has **two** (graphical + text mode). The
+   single-entry template is the appliance image. Both updated.
+2. **"27 Hungarian printf lines"** — **25**.
+3. **"No test compares the banner text itself"** — one greps the painted banner, and another `cmp`s
+   `/etc/issue` against the `postinst`'s copy **byte for byte**. The console seam already existed too.
+4. **"VM 321/322 were used"** — not confirmed; no VM was created (see Stop).
+5. **"the site is published as its CHANGELOG says"** — right: push to `main`, git-sync, ~1–2 min.
+   Verified live.
+6. The publish runbook does exist (`documentation/runbooks/iso-release-gate.md`) and is correctly not
+   in the ISO README.
 
-**Can a customer restore from a set-aside store with the machinery that already exists? NO — and
-building it is new surface, not wiring.** Established read-only, at `file:line`, before a line was
-written.
+## Two defects found before any feature work
 
-Every restore entry point resolves the repository from `settings.GetOffboxTarget()` and the password
-from the single `offboxPwPath()` file: `offboxLatestSnapshot` (`offbox_restore.go:85-86`),
-`offboxSnapshotSize` (`:139-140`), `RestoreOffboxScratch` (`:206+`). **A grep for a repo-path
-parameter anywhere in the restore chain returns nothing.** The only seam that installs a recovered
-password, `InjectOffboxPassword` (`offbox.go:667`), writes that same one file — i.e. **adoption**.
+**R-586 — the ISO harness had been RED for two days.** Run unchanged at the base commit it failed two
+R-496 checks. The script paints with `> "$CONSOLE_DEV"`; on a console that is a device and truncation
+is a no-op, but the harness pointed it at a plain FILE, so each banner erased the previous one. ISO
+1.28.0's new bound banner (`c033b3b`, 2026-09-16) paints straight after the pairing banner and wiped
+it. That commit did not touch the harness, and **the harness is in no gate and no CI run**, so nobody
+saw. Fixed with a FIFO; production code untouched. Its being ungated is still open.
 
-What the drill did to read the set-aside store was `restic` **by hand**, with `-r <alt repo>` and an
-overridden `RESTIC_PASSWORD_FILE`. **That distance is exactly what (b)-to-(c) costs.**
+**The release gate would have stopped the task the operator asked for.** G16 read *"every
+Felhom-authored string is Hungarian — PASS = no English sentence"*, encoding the 2026-07-31 scope.
+**Ruling 1b of 2026-09-17 supersedes it.** G16 was **rewritten, not waived**: Hungarian FIRST, pinned
+by a golden, each secret named once per language.
 
-**So the session halted at Part 3 by its own rule, shipped Part 2, and hands back options → R-312.**
-Cost to find out: ~35 minutes, read-only.
+## What shipped
 
-## 2. Part 0 — the countdown, cancelled on your ruling
+Bilingual pairing banner, bound banner and `/etc/issue` (plus `postinst`'s byte-coupled copy);
+English halves on both GRUB entries; `website/en/download.html` **live**, linked both ways with
+`hreflang`; `letoltes.html` changed by **four lines** and nothing else.
 
-Through the product's own operator path (`--abandon-stop`, which refuses rather than silently
-no-opping), with the container **stopped first** so the running controller could not overwrite
-`settings.json` from memory. **Proved, not trusted to the exit code:**
+**The link is not in the nav** — the nav is a shared block `site_gates.py` pins across every page, and
+the gate convicted my first attempt, which is how the link found its right home.
 
-- `abandon_started_at` and `abandon_at` — **gone**. `AbandonStatus` returns `Active=false` when
-  `AbandonAt` is empty (`offbox_abandon.go:111-113`), so no countdown renders.
-- `abandon_repo_path` — **deliberately kept**, as the pointer to the preserved store.
-- The set-aside store — **still there**: 36 snapshot objects, full `config/data/index/keys/locks/
-  snapshots` structure. Both repositories still on the endpoint. **Nothing deleted anywhere.**
+## Proven, not read
 
-**And the thing you should know about what was preserved (R-313):** it holds **36 snapshots and one
-key slot**, and it does **not** open with the box's current password (`Fatal: wrong password or no key
-found`, exit 1 — measured). Its key is the one hashed `48741892f0ef…` — retained row id 4,
-`identity_blob` **NULL**, a pre-v0.93.0 row. **The material was dropped by the R-198 defect during its
-two-month window, so no recovery code in existence opens that store.** Keeping it is still the right
-call — deleting is irreversible and a decision, not an accumulation — but it is 36 unreadable
-snapshots, and that is the concrete, still-present cost of R-198 sitting on the endpoint.
+Hungarian **goldens** captured before one English line existed; the harness asserts each banner's
+first N lines are exactly the golden. English blocks carry no Hungarian letter (Hungarian block =
+positive control). Every line ≤ 80 **columns**, counted in characters because the Hungarian lines are
+multi-byte. **The whole paint ≤ 25 rows.** All red-proofed — a changed byte, a planted `ó`, an
+over-wide line, two extra lines.
 
-## 3. Part 2 — what shipped, and a correction to the premise
+**The pairing banner is 24 rows on a 25-row console.** One row of margin, which is exactly why the
+height is now pinned: two more lines and the **Hungarian** code at row 5 scrolls off the top.
 
-**The premise needed correcting first.** The task described the customer being told *"the recovery code
-did not open the sealed bundle"*. That is the **agent's local-API** reply. The **customer-facing
-screen already hedged** (R-222/R-226) — it named both causes, named the kept package and its date, and
-said it could not tell them apart. That was **honest**; it could not tell them apart **because nothing
-ever looked**. So what shipped is smaller and more precise than "stop the lie": **the hedge becomes an
-answer.**
+Against the built ISO: G1, G2, G5, G6, G7, G9, G16 all pass — including both payload files
+**byte-identical to repo HEAD**.
 
-- **hub v0.103.0** — `GET /hosts/<id>/escrow/retained`, the **first production caller
-  `ListSupersededEscrow` has ever had**. Self-scoped identically, same recovery-mode gate, same audit
-  event written before the bytes leave, capped at 16. Rows with a NULL `identity_blob` are **withheld
-  and counted** (`unopenable_count`): they can never open what the caller is asking about, and serving
-  them would let the screen promise recovery on exactly the boxes the original defect hurt.
-- **agent v0.129.0** — retained packages tried **only after** the current one refuses; `422` with
-  `superseded_at`; bounded at 6 attempts (~1 s of scrypt each); fail-safe in every direction.
-- **controller v0.214.0** — class `RecoveryCodeOpensRetained`, gated on MinAgent **0.129.0** via a
-  **second, separate** trust flag (a box can sit between 0.126.0 and 0.129.0). The message says the
-  code is correct, names the date, says the package is kept, says the **current** backups are
-  unaffected, and **promises no restore** — it routes to support, which can do it.
+## STOP — the image is built, not published
 
-**The trade you should see stated:** the hub still cannot read any of it — sealed bytes in, sealed
-bytes out, no decrypt path, no recovery code ever held. What widens is **volume**: a host key that
-could fetch one opaque package can now fetch N, bounded by self-scope, the recovery-mode gate and the
-cap.
+`felhom-installer-1.29.0-pve9.2-1.iso`, sha256 `c67ceaa3793b38639d0f24c9c9704270d04e50b74f1ea88b1129fdd1dec6fb02`.
 
-## 4. Red-proofs — and where the lie actually lives
+Publishing is public and irreversible and the runbook needs, against the uploaded bytes: a **proof
+install on BOTH menu entries**, a reboot (G15), a person choosing the disk (G14) and a round trip
+(G11). That is supervised. **The download pages therefore still name 1.28.0** — the published image —
+because pointing them at a file that is not there would hand every reader a 404. The new gate stops
+anyone updating one page and forgetting the other.
 
-Every mutation asserted to have applied before its run.
+**No VM created, none destroyed. demo-hp guest 9201 untouched. No floor, no golden.**
 
-| Repo | Mutation | Outcome |
-|---|---|---|
-| hub | serve the CURRENT row instead of retained | FAILS (count 2→1) |
-| hub | drop the unopenable guard | FAILS (count 1→2, unopenable 1→0) |
-| hub | drop self-scope | FAILS (403→200) |
-| hub | collapse the route suffix | FAILS (count 1→0) |
-| **agent** | **remove the retained lookup** | **FAILS — the fail-closed wrong-code error returns. THE LIE COMES BACK.** |
-| agent | + 6 more (nil fetcher, wrong code, fetch failure, bounded attempts, predates-field, success path) | all pinned |
-| controller | delete the new case | FAILS — but the customer gets the **neutral** message, because R-224's safe default catches it |
-| controller | make 422 unconditional | FAILS — an agent that never looked is read as having looked |
-| controller | route 400 to the new class | FAILS — a mistype is congratulated |
+## Rows
 
-**Answering the question directly:** the lie returns when the **agent's** retained lookup is removed,
-not when the controller's case is. R-224's safe default is doing its job one layer up.
+**R-586** (harness red, ungated) · **R-587** (two root-password files sit in the ISO publish source
+directory; both 404 on the bucket against a 200 control, so not leaked — the only thing keeping them
+off is an `--include` pattern they miss by naming accident) · **R-588** (release records live in two
+different places; it made me wrongly conclude 1.28.0's gate had never been run).
 
-## 5. The claim guard, and a gate whose positive control failed
+## Green
 
-**The claim guard had a blind spot the size of the recovery screen** — it scanned templates only,
-while every recovery message is a Go string in a handler. It now scans `recovery_handlers.go` too, and
-**on its first run convicted a pre-existing unregistered claim**. 8 → 10 registered claims.
-
-**The wire-contract gate: declared, and honestly weaker than it looks (R-315).** The hub response was
-made a **named type** so the gate could resolve it; the wire is declared as a fourth ROOT and the tag
-count rose **174 → 182**, so the fields are inspected. But a positive control — renaming the
-agent-side `superseded_at` tag — **still passed**, because the check is repo-wide name-presence and
-the string also occurs as a map key elsewhere. The gate documents this ("name-reachability is not
-use"), so it is a known limit, not a regression — **but declaring this wire bought documentation, not
-enforcement**, and saying otherwise would have been false.

-WRONG code (negative control)      HTTP 400  "the recovery code did not open the sealed bundle"
-```
-
-The hub half measured directly too: `GET …/escrow/retained` → **200**, `count=2`,
-**`unopenable_count=1`** — that one being retained row id 4, the pre-v0.93.0 row whose material R-198
-destroyed. The withholding rule is doing exactly what it was written for, on real data.
-
-**What was NOT walked, and why.** The customer's rendered sentence was **not** produced end-to-end.
-`recoveryUnlockHandler` redirects to `/backups/remote` when `!recoveryOffer()`, and `demo-felhom`
-holds its own repository password again (restored yesterday), so it is correctly **not** in the
-offered state. Walking it would mean removing that password to fake a rebuilt box — destabilising a
-healthy machine to render a sentence whose logic is pinned by six handler tests and whose upstream 422
-is proven live. I did not. **Method stated: endpoint-level for the agent and hub, handler-level for the
-message.** What the customer DOES see on this box today is the orphan card, and it is honest:
-*„Megnyitni innen egyelőre nem lehet, és ez nem a kódodon múlik."*
-
-### A correction I have to make about my own last report — R-308 was wrong
-
-I reported that the stored controller password no longer opens `demo-felhom`. **It does.** I had
-stripped only DOUBLE quotes from the `~/.config/credentials` value; the values are wrapped in
-**SINGLE** quotes, so I was sending a literal `'` as part of the password. Unquoted correctly it is 13
-characters and logs in first try — **HTTP 302 with a session cookie**.
-
-The same bug then made this session's first live R-311 test read as a **failure** (HTTP 400) for
-twenty minutes, and I nearly filed the fix as broken. It is the **third** wrong "the credential is
-stale" verdict this project has produced from that one trap. R-308 is **withdrawn**; the real lesson
-is filed with it — never let a shell decide what a secret is.
-
-## 7. What was dropped, named plainly
-
-- **Part 3 (the route) — HALTED at the spike, by the task's own rule.** → R-312.
-- **§7's fixture walk was not re-run end-to-end.** Yesterday's drill already proved the byte-identical
-  restore from a set-aside store; today's change is upstream of it (which sentence is shown), the
-  dashboard is unreachable headlessly (R-308), and the restore route does not exist (R-312). What was
-  proved live is the 422 itself.
-- Explicitly out of scope and still open, so it does not read as forgotten: **R-305** (the removal fix
-  helps a machine once — the tester's second reinstall still hits it), the hub emails naming the
-  retired secret, **R-309** (the runbook's publication claim), the CI runs that fail with no log, the
-  twenty unread facts, the nine grey claims, **R-303**.
-
-## 8. Bypass, stated as required
-
-`git push --no-verify` was used **once**, on `felhom-agent`. The `release-complete` gate refuses a
-CHANGELOG entry whose tag and package do not exist; `release-agent.sh` refuses a tree that is not
-pushed. Circular by construction. The bypass was immediately followed by the real release
-(`release-agent.sh 0.129.0`), and the gates were re-run afterwards: **green**.
+`bash -n` + `shellcheck` clean on both scripts · harness **71 checks, all pass** · `site_gates.py` OK ·
+`repo_gates.py --fast` all 14 OK.

+
+### 1. The catalog syncer rewrites the file under a running app, on a 15-minute cycle
+
+`Syncer.copyTemplates` (`sync/sync.go:319`) walks every directory in the catalog cache and copies
+`docker-compose.yml` and `.felhom.yml` into the matching stack folder. **There is no test of whether
+the app is deployed.** The only guard is a sha256 content compare (`copyIfChanged`) and the only
+exclusion is `app.yaml`. Interval is `git.sync_interval`, default `15m` (`config/config.go:351`), plus
+one immediate sync at controller start (`sync.go:98`).
+
+**SINCE v0.235.0** this walk still happens and `.felhom.yml` is still copied unconditionally, but the
+compose file goes through `Syncer.renderSource`, which consults a per-app plan supplied by the stack
+manager (`Manager.RenderPlanFor`) through a nil-safe seam. A nil seam is byte-for-byte the behaviour
+described above.
+
+**It restarts nothing.** The post-sync hook is `stackMgr.InjectMissingFields(updated)` and nothing
+else. So from the moment it runs, a deployed app's *definition* and its *running containers* disagree,
+and they stay that way until something else acts.

+is absent** — measured at 18.3 s with a pull versus 0.5 s without, against a negative control

+- the drive-return gate, `web.Server.restartStacks` → `StartStack` — `web/intermediary.go:222`
+
+**A plain power cut does NOT trigger this.** Docker's `restart: unless-stopped` restores the existing
+containers on the old image, the reconciler finds no orphan, and it logs so
+(`no boot-orphaned apps (nothing to start)`). The unattended upgrade needs the narrower precondition
+*"and the app did not come back"* — which was measured, and does upgrade.
+
+### 3. Nothing takes a copy first, and the tag cannot be put back afterwards
+
+`UpdateStack` runs `compose pull` then `compose up -d --remove-orphans` and does nothing else — no
+dump, no copy, no hold. The R-361 safety dump (`backup/offbox_reconstitute.go:207`) is **database-only**
+and is not on this path at all; an app with no database gets nothing from it even on the paths where it
+does run.
+
+**And restoring the old tag is not a rollback.** Once an app has migrated its data, the old image
+refuses to start — measured on Nextcloud: *"the version of the data (32.0.9.2) is higher than the
+docker image version (31.0.14.1) and downgrading is not supported"*. The data itself survives; only the
+downgrade is blocked. So the only route back is a **data** restore from a copy taken before the
+update.
+
+**And that route fights this seam** (R-441): `stackAdapter.RecreateStackDefinitionFromUnit`
+(`cmd/controller/main.go:2570`) writes the recovery unit's captured compose — with the OLD pin — into
+the live stack dir, and `copyIfChanged` overwrites it again on the next tick. The overwrite is
+measured; that the restore writes to that path is read, not measured.
+
+### What a change here must not break
+
+- The syncer's overwrite is also the **repair** path: a locally-corrupted compose is replaced by the
+  catalog's version within 15 minutes (observed). Any "don't touch deployed apps" rule loses that.
+- `up -d`-on-restart is what injects `app.yaml` env into a running stack. Reverting to
+  `docker compose restart` would silently stop doing that.
+
+## App settings after install [DESIGN, recorded 2026-09-15]
+
+**An installed app's settings are read-only on its page** („Ez az alkalmazás már telepítve van. Az alábbi
+beállítások csak olvashatók.", `deploy.html`). This is a design, not an oversight: a changed value would
+need a guarded re-deploy that nothing performs. **Finding (2026-09-15):** the catalog field flag
+`locked_after_deploy` (`stacks/metadata.go`) is parsed and read by **no** controller code — every field
+is read-only after install whatever the catalog says. So a page must never tell a household to change
+a value after install. **Vaultwarden (R-512)** follows the design instead of breaking it: registration
+is closed by default and the household is invited from the admin panel, measured to work without mail
+(stranger 400, invite 200, invited 200).

A compromised hub cannot forge them because the signing key is **not held by the hub** (it lives with the operator / a separate signing path; the hub only queues opaque signed blobs).
 - **Data-bearing-ness is agent-internal evidence, never a caller's claim (slice 8C).** For a customer-driven storage op (`POST /disks/format`, §6) the agent **inspects the actual device** (filesystem signature / partition table / partitions / mount, conservative — ambiguous → data-bearing) to decide the class.

+  (`/var/lib/felhom-agent/guests/<vmid>/bootstrap` exists) that is running, whether
+  `felhom-controller` is running; on the **second** consecutive "no" it runs

+  the same two sudoers grants. **Guards:** not during a controller swap; not when parked
+  (`touch /var/lib/felhom-agent/guests/<vmid>/controller-parked` on the host); not on a stopped,
+  locked or vzdump-busy guest; not on an unknown docker answer; and no thrash — 3 restarts in 15 minutes
+  stop restarts for 30 minutes. **Events:** the agent has no event channel; its host report carries a
+  `controller_supervisor` stanza, and the hub mints `controller_restarted_by_agent` (info) and
+  `controller_crashloop` (error), both operator-only, keyed on timestamps so an agent restart can
+  neither lose nor invent one. New goldens run the controller with `--restart always`, which covers
+  only a Docker daemon restart.

+61 s / 41 s / 61 s), and **none of them accumulated**, because the budget window is 15 minutes — so
+the 30-minute pause was never armed and the only trace was an `info` `controller_restarted_by_agent`
+event, which mails nobody. A box whose controller dies every 20 minutes is therefore restarted
+for ever, quietly. **The 3-in-15-minutes budget is unchanged**; what is owed is a second counter over

+brake: restarts the supervisor performed in the last **24 hours**; at the **fifth**, the heartbeat stanza
+sets `slow_crashloop_since` (moving at most once per 24 h) and the hub raises
+`controller_slow_crashloop` (**warning, operator-only**). It never stops restarting — the fast brake stays

+
+The box's console tells the volunteer to open „az e-mailben kapott link". That mail must exist whenever
+a customer is **waiting for a box**, without an operator press. `autoMintSelfBindLink` runs on four
+events: **customer creation**; **RESET completion**; **an e-mail set or changed on a customer with no
+bound host** (config save); **a host delete** that keeps the customer. The last two re-check that no
+host is bound, so a customer who has a box is never sent a pairing link. **Appliance registration is
+not a trigger** — it knows no customer (`api/appliance.go`). Every send is stored as a hub-internal
+`selfbind_link_sent` event with its occasion; the Setup tab shows „Kapcsolódó link elküldve: <date>
+(<occasion>)" and keeps the button as the manual resend. Until 2026-09-15 only the first two existed,
+and BIGNIGHT's tester-1 never got its mail (R-509).
+
+## 14. The PBS-DR descriptor and its endpoint token — lifecycle [DESIGN, recorded 2026-09-15]
+
+Two records must agree: the **token** on the endpoint (ep0: namespace `<customer>` + token
+`felhom@pbs!<customer>`) and the **descriptor** in the host's `desired_json` (`pbs_dr`: namespace,
+token id, fingerprint, datastore, tunnel IP, `secret_generation`) with its consume-once secret.
+
+| event | token on ep0 | descriptor on hub |
+|---|---|---|
+| DR tier ON + WG peer present (form save or WG hook) | **provision** | created, secret stored |
+| re-issue, descriptor present | **re-keyed** (delete + recreate) | `secret_generation` bumped |
+| **re-issue, descriptor ABSENT, DR flag on** (R-511, v0.114.0) | **adopted**: re-keyed | **rebuilt** from the endpoint's answer; `pbsdr_adopted` audit row |
+| host delete | **kept** (tenancy survives) | goes with the host |
+| host delete acknowledged through escrow-ack, then a new box | re-keyed automatically (F-14) | rebuilt |
+| RESET / customer delete | **deprovisioned** — namespace, every backup group AND token | purged |
+
+**Why adopt exists:** a rebuilt box's WG hook refused („the endpoint already holds a PBS token … use
+the explicit Re-issue action") and the re-issue itself then refused with 400 — no button restored the
+tier. **Not built:** releasing ONLY the token on host delete. The endpoint's only removal op
+(`deprovision`) destroys the backups too, so a token-only release needs a new endpoint operation.
+
+## 15. Customer e-mails — what the hub writes to a household [hub v0.118.0, R-558]
+
+**The section this document did not have.** The hub composes every sentence a household reads before
+it has seen any box screen, and until v0.118.0 nothing here described that.
+
+### 15.1 The four mails
+
+| Mail | Trigger | Rendered by | Language source |
+|---|---|---|---|
+| Event notification (39 event types) | a box event, or a hub checker | `FormatCustomerEmail` | reported → created-with → `hu` |
+| Claim / reset / re-enroll / claimed | the claim arc | `FormatClaimEmail` | created-with (no box has reported yet) |
+| Self-bind link | customer creation, or the operator's button | `FormatSelfBindEmail` | created-with |
+| The public bind PAGE at `/bind/<token>` | the customer opens the link | one template per language | created-with, **except `expired`** — see 15.4 |
+
+The operator's channel (`FormatOperatorEmail`, and the R-182 backup-run digest) is **not** in this
+table and is not localised. It is English, it names host ids and blob counts, and it is untouched.
+
+### 15.2 Where the sentences live
+
+`hub/internal/i18n/locales/{hu,en}.json`, one flat key→text map per language. Hungarian is
+authoritative and holds every key; a key missing from English renders the Hungarian and is counted by
+a gate held at zero. `customerMessages` and `severityLabels` are DERIVED from the bundle rather than
+being literals, so a sentence is written in exactly one place. **A new event type therefore needs a
+line in `hu.json` and its English twin**, alongside its `allowedEventTypes` entry — the long-standing
+"both together" rule, in its new home.
+
+### 15.3 The language order, and why it is that order
+
+**Last reported → created-with → Hungarian** (`Store.CustomerLanguage`).
+
+1. **What the box last reported** is what the HOUSEHOLD chose on their own dashboard. It outranks
+   everything else: the operator's creation-time pick is a default, never an override.
+2. **The creation-time language** (`customer_configs.language`) covers the window before any box has
+   reported — which is precisely when the claim mail and the bind page are sent, so it is not an edge
+   case. It also seeds the box: configgen writes it as `customer.language`.
+3. **Hungarian**, for every customer that predates all of this.
+
+Two storage rules follow from that order and are easy to get wrong:
+
+- `reports.language` defaults to **empty**, never `hu`. Empty means *this box has never told us*,
+  which is not the same as *this household chose Hungarian* — a controller older than v0.247.0 sends
+  no language at all, and storing `hu` would make a later real choice indistinguishable from the
+  absence of one.
+- The newest report is found by the autoincrement **`id`**, not by `received_at`. `received_at` has
+  second granularity, so two reports arriving in one second tie and the winner is arbitrary.
+
+A quiet-box alarm deliberately uses the last REPORTED language even though the box is silent: the
+last thing it said is still the best thing known about the household.
+
+### 15.4 The box's own sentences, and the one thing the hub cannot do
+
+About a third of the customer mails carry a sentence the BOX composed, naming a drive, an app or a
+number. **The hub cannot translate one.** So the box sends the household's version beside the
+Hungarian one, as `message_customer` on `POST /api/v1/event`; the hub puts that in the household's
+mail and keeps the Hungarian for the operator's. It is additive and optional **forever** — a parked
+box will never send it, and its absence must leave the mail exactly as it was.
+
+Until every box runs controller v0.256.0 or later, an English household's mail can carry one
+Hungarian line. The rest of the mail is English. That is expected, not a defect.
+
+**The bind page is a no-oracle surface, and the LANGUAGE is part of that.** The page folds an unknown
+token into `expired` so a stranger cannot learn whether a link was ever real. If it then rendered a
+real English customer's expired token in English and an unknown one in Hungarian, the language would
+answer the question the text refuses to — for every customer who is not Hungarian. The `expired`
+state therefore always renders in the default language; every other state already discloses that the
+token is real. Pinned by `TestBindExpiredIsAlwaysDefaultLanguage`.
+
+### 15.5 How "the Hungarian did not change" is known
+
+56 goldens captured from v0.117.0 before any string moved, in
+`hub/internal/notify/testdata/mail_goldens/hu/`, with the English set beside them. The claim is a
+diff, not a reading. A golden is never regenerated to make a change pass.

+# 08 — The app-down alarm ladder
+
+**Written 2026-08-23, with controller v0.222.0 (R-384).**
+
+**The absence is the finding.** Until this file existed, no document owned the question *"when does a
+customer's app being broken raise an alarm?"* The rules were spread across four packages as comments,
+each locally correct, and the ordering between them was legible only by reading
+`aggregateState` top to bottom. That is exactly how R-384 survived: every individual rule was right,
+and the composition was wrong. Three separate defects in this ladder (R-51, C9-F2, R-384) were each
+found on live hardware rather than by review, and each is a case where a reader could not see the
+whole ladder at once.
+
+Everything below is **[DESIGN]** — deliberate, with the reason recorded — unless marked otherwise.
+
+---
+
+## 1. The two questions, and their order
+
+Two different questions get asked about a multi-container app, and **the order between them is
+load-bearing**:
+
+1. **Is a SUPERVISED member of this app dead?** — a container Docker's restart policy says should be
+   running, that is not.
+2. **Is a RUNNING member failing its healthcheck?**
+
+**Question 1 is asked FIRST.** [DESIGN, R-384, v0.222.0]
+
+Until v0.222.0 it was asked second, and the consequence was not subtle: a two-container app whose
+database exits goes `unhealthy` seconds later *because it cannot reach that database*. So the symptom
+the dead database causes was the thing that suppressed the alarm for it. Measured on `demo-hp`
+2026-08-22 — `bookstack-db` stopped at 21:27:01 and the watcher reported `0 currently down`
+throughout.
+
+**"Some members are up" means any member NOT in the down bucket** — `running`, `unhealthy`,
+`starting` or `restarting`. [DESIGN, R-384] The earlier guard was `running > 0`, counting only
+`StateRunning`, which made the supervised test unreachable in precisely the case it was written for:
+an unhealthy survivor beside a dead database counted as nothing being up.

+| is a down member supervised? | `internal/stacks/manager.go` `supervisedPolicy` | `no`/`on-failure` benign; everything else, **including unknown**, supervised |
+| which states mean "down" | `internal/stacks/manager.go` `IsDownState` | `{stopped, exited, degraded}` |
+| stack state → "this app is down" | `cmd/controller/main.go` `classifyRunStates` | **the single derivation point**; all three suppressions live here |
+| sustained restarting → down | `internal/stacks/manager.go` `CrashLooping` | 5-minute threshold |
+| quiesce suppression | `internal/quiesce/suppress.go` | cycle-keyed, 180 s grace |
+| boot repair | `internal/bootrecon/bootrecon.go` | consumes `IsDownState` |
+
+---
+
+## 3. The aggregation ladder, in order
+
+`aggregateState(containers, policyOf)` — **priority: degraded > unhealthy/starting > restarting >
+all-running > stopped.**
+
+1. no containers → `not_deployed`
+2. **any DOWN member is supervised, and any member is up → `degraded`** ← R-384 put this first
+3. any `unhealthy` → `unhealthy`
+4. any `starting` → `starting`
+5. any `restarting` → `restarting`
+6. all running → `running`
+7. all down → `stopped`
+8. mix, every down member benign → `running`
+
+Step 2's `policyOf` is consulted **only** for the down members, and only when something is up. `nil`
+is allowed; every down member then reads as supervised.
+
+---
+
+## 4. Which states alarm, and which deliberately do not
+
+`IsDownState` = `{stopped, exited, degraded}`.
+
+| State | Down? | Why |
+|---|---|---|
+| `stopped`, `exited` | **yes** | not running, will not recover alone |
+| `degraded` | **yes** | [DESIGN, R-51] a dead supervised member is as unreachable as a single app that exited — immich-server sat Exited 18 h with the app 100 % dead and no alert |
+| `unhealthy` | **NO** | [DESIGN] a running container whose healthcheck is failing. Folding it in reintroduces the flapping fix-3 was written to stop. **R-384 did not change this** — it asks a prior question instead |
+| `restarting` | **NO**, until sustained | [DESIGN, C9-F2] `restarting` is on the normal deploy path, so folding it in would alarm fleet-wide on every update. Becomes down after **5 min** (`crashLoopAfter`) |
+| `starting`, `deploying` | no | mid-start |
+| `paused` | no | a deliberate user action |
+| `unknown` | no | [DESIGN] fail-OPEN — never manufacture a dead-app alert from an inconclusive read |
+
+**Note the two fail directions are deliberately opposite.** `IsDownState` fails OPEN on `unknown`
+(ambiguous *state* → do not alarm). `supervisedPolicy` fails CLOSED on unknown (we already KNOW a
+member is dead; only the excuse is missing). Both are recorded at their sites.
+
+---
+
+## 5. The three suppressions, all at `classifyRunStates`
+
+| Suppression | Rule | Expires? |
+|---|---|---|
+| **deliberate user stop** | `StateStopped` is not down **unless** the quiesce loop reports it failed to restart that stack | n/a — lifted by `failedRestart` |
+| **quiesce cycle** | a stack this backup cycle stopped is exempt | **yes**, 180 s after unquiescing |
+| **boot grace** | no evaluation for 90 s after controller start | **yes** |
+
+**None of them latch.** [DESIGN, R-97b + R-88 Scenario D] A permanent suppression trades a loud false
+alarm for a silent real one, which is the same error as an over-eager alarm, in the opposite
+direction. Every window expires; the cost is a bounded DELAY in reporting a real failure, never its
+loss.
+
+The quiesce suppression is **cycle-keyed, not state-keyed** — an app caught mid-restart is
+`starting`/`unhealthy`, not `stopped`, so no state test can see it. It is therefore **state-blind**,
+which is why R-384 moving a stack from `unhealthy` to `degraded` cannot weaken it.
+
+---
+
+## 6. The alarm itself
+
+Edge-triggered: `app_start_failed`, one event per transition into down, **not** per scan. Verified
+live 2026-08-23 — one event across 22 scans.
+
+- **Operator/hub event + dashboard banner.** `app_start_failed` is **not** in
+  `settings.DefaultEnabledEvents`, so by default it does **not** e-mail the customer.
+- **F-OBS heartbeat**, every 20 scans (~10 min), at `[INFO]`:
+  `[deadapp] check alive: N scans since boot, M deployed app(s) evaluated, K currently down`.
+  This line exists because an absent alarm and a stopped detector look identical in a log.
+
+### 6.1 The severity contract [DESIGN, R-329 — CLOSED controller v0.223.0 / hub v0.107.0]
+
+**The vocabulary is the HUB's and it is exact: `{info, warning, error, critical}`.** Anything else is
+**coerced to `info` at ingest**, and `info` is dropped by `severityNotifies` before *both* delivery
+legs. So a severity outside the set means the event is stored, answers `200`, shows on the dashboard —
+and is e-mailed to **nobody**.
+
+**This shipped twice.** `DiskAlertKind.Severity` emitted `"warn"` until controller v0.215.0;
+`app_start_failed` emitted it until v0.223.0. Measured on the live hub DB 2026-08-23: **91
+`app_start_failed` events stored all-time, ZERO `notification_log` rows before that day** — not one,
+on any channel.
+
+Three things now hold it:
+
+1. **The emitter is pinned by an AST walk** over the whole controller
+   (`TestR329_EveryEmittedSeverityIsInTheHubVocabulary`). Not grep — "warn" is a legitimate
+   *healthcheck status* in `internal/monitor` and `internal/selftest`. The six call sites that pass a
+   variable are registered by name with the values each can take, so a new dynamic path fails.
+2. **The hub SAYS SO** when it coerces (hub v0.107.0, R-387): a `WARN` naming the customer, the event
+   type and the rejected value. **The coercion stays** — a rejected event is a *lost* event, and
+   losing an alarm is worse than mis-routing one.
+3. **The dispatcher's `unrecognized severity` branch is kept**, because the hub's own monitor checkers
+   call `ProcessEvent` directly and never pass the ingest handler. For them it is the only guard.
+
+**Who gets it.** `processOperator` consults only `operatorOn`, the address and a 1-hour cooldown —
+**never customer preferences** — so a valid severity always reaches the operator. `processCustomer`
+consults `operatorOnlyEvents` and then the customer's `enabled_events`.
+
+**`app_start_failed` is customer-switchable but OFF by default** [DESIGN, operator ruling 2026-08-23]:
+it is deliberately absent from `DefaultEnabledEvents`, and deliberately **not** in `operatorOnlyEvents`
+— being in that register would make the toggle visible, flickable and structurally unable to deliver.
+
+**`backup_integrity_ok` / `backup_integrity_failed`** [DESIGN, R-359/R-397 — controller v0.227.0]. Both
+existed in `internal/notify` with **no caller** until v0.227.0 wired them; the hub had allowlisted both
+and carried the Hungarian customer text for both the whole time.
+
+| event | severity | reaches | why |
+|---|---|---|---|
+| `backup_integrity_ok` | **`info`** | **NOBODY** | `severityNotifies` drops `info` before both legs, and that is the intended outcome, not an oversight. **A weekly success e-mail is how people stop reading their alerts.** It is still pushed and stored, because the event stream is where "was it checked?" is answered — the dashboard reads it, the inbox does not |
+| `backup_integrity_failed` | `error` | operator always; customer if enabled | the customer's backups may be damaged, which is the loudest fact this tier can produce |
+
+**`backup_integrity_failed` is deliberately in NONE of the three registers**, and all three were checked
+rather than assumed (2026-08-30):
+
+- **not** in `perAppCooldownEvents` — there is ONE store, not one per app. The coarse per-type hourly
+  key is correct here, and adding it would be a fenced act under §6.2 for no gain.
+- **not** in `operatorOnlyEvents` — the operator leg ignores customer preferences anyway, so the
+  operator is always mailed; putting it here would only remove the customer's ability to opt in.
+- **not** in `DefaultEnabledEvents` — customer-switchable, default OFF, the same ruling as
+  `app_start_failed`. The checkbox already exists at `settings_notifications.html:34`.
+
+**And a caveat that belongs in the alarm ladder rather than only in the backup document:** a
+`backup_integrity_ok` at the shipped depth means *the index, the pack inventory and the snapshot graph
+are sound*. It does **not** mean the stored bytes were re-read — measured 2026-08-30, a pack corrupted
+without a size change passes the structure check with `no errors were found`. An `ok` here is a real
+signal about a real class of failure, and it is narrower than the phrase suggests (R-399).
+
+---
+
+## 6.2 The delivery grain — how often, and per what [DESIGN, R-389 — hub v0.108.0]
+
+**"How loud" is a separate decision from "does it alarm", and it is made in one place**: the operator
+cooldown key at `processOperator`. Everything sharing a key is collapsed for **one hour**.
+
+**Operator ruling 2026-09-15 (decision A) — „the box is down" skips the quiet hour.** `node_stale`,
+`node_down` and `node_recovered` no longer share the one-hour operator cooldown; they keep a **5-minute
+dedupe** on the same key, so a flapping link cannot mail every sweep (`operatorCooldownFor`, hub
+v0.114.0, pinned by `TestOperatorCooldown_NodeLivenessBypassesQuietHour`). **This reverses the design
+above for those three types only**, and it is a ruling, not a defect fix. The reason is BIGNIGHT F9
+(2026-09-14): the controller was dead for 33 minutes; its `node_stale` mail was suppressed because F8's
+`node_stale` had used the hour 39 minutes earlier, and the later `node_recovered` mail was suppressed
+the same way. **EXTENDED by operator ruling 2, 2026-09-16 (hub v0.115.0, R-529): `host_stale`, `host_down` and
+`host_recovered` join the bypass**, with the same 5-minute dedupe. They are the same sentence about the
+same box — the agent's dead-man's-switch rather than the controller's — and leaving them on the hour
+would have kept exactly the F9 silence on the host plane. Everything else keeps the hour (pinned by
+`TestOperatorCooldown_NodeLivenessBypassesQuietHour`, which also asserts an unrelated type still waits).
+
+**Operator ruling A, 2026-09-17 (R-549) — „the box went quiet" waits THREE report cycles, not two.**
+The staleness threshold (`alerting.stale_threshold`, configuration in `manifests/hub.yaml`) moves from
+**30 m to 45 m**; `node_down` and `host_down` follow at 2× = **90 m**. The reason is chaos night round 9
+(`audits/DRILL-chaos-night-2026-09-17.md`): report cadence 15 m; a failed push is retried for ~100 s and
+then given up (correctly — a report is a snapshot); the measured gap to the next good report was
+**29 m 59 s** against a 30-minute threshold. One missed push spent the entire budget, so ordinary jitter
+would page the operator about a box that was healthy and had already repaired itself. **The cost,
+stated:** a truly dead box now pages 15 minutes later (45 m instead of 30), and „the box is down" 30
+minutes later (90 m instead of 60). **One value, everywhere:** both staleness checkers, the host status and
+— since hub v0.117.0 — the customer status on the dashboard read the same threshold (`controllerStatus`
+hardcoded 30 m / 1 h until then; pinned by `TestControllerStatus_FollowsConfiguredThreshold`). A running
+hub prints it at startup (`node_stale after 45m0s, node_down after 1h30m0s`).
+
+**Two event types added 2026-09-17, with who receives them:**
+
+| event | severity | who | minted by | why that audience |
+|---|---|---|---|---|
+| `controller_slow_crashloop` | warning | **operator only** | hub, from the agent's `slow_crashloop_since` moving (agent v0.132.0, hub v0.117.0) | host ids and vmids; the household's side of it is the dashboard coming back each time |
+| `restore_interrupted` | warning | **the household** (and the operator) | controller v0.246.0 at startup, once per interruption | they pressed restore, were told it started, and can run it again — Hungarian `customerMessages` entry |
+
+| Family | Grain | Key carries | Why |
+|---|---|---|---|
+| app down (`app_start_failed`) | **per APP** | `…:<stack_name>` | no digest exists for it — see below |
+| backup run (`backup_run_failures`) | per RUN | `…:<run_id>` | a digest already lists every failing app; one per run |
+| tiered backup (`whole_guest_backup_failed`, …) | per TIER | `…:<tier>` | the tiers fail independently and mean different things |
+| everything else, incl. `crossdrive_failed` and `backup_integrity_failed` | per TYPE, per hour | — | coarse **on purpose** |
+
+**The default is COARSE and that is deliberate.** R-97a and R-182 exist so that one full disk produces
+**one** mail listing every affected app rather than one per app. Widening the grain is what makes an
+operator stop reading their alerts, which is the same failure as not sending them.
+
+**`app_start_failed` is the exception because it has no digest.** There is no `apps_down_run`
+summarising a scan the way `backup_run_failures` summarises a run, so per-app is the only grain
+available that does not lose alarms. Until hub v0.108.0 it was keyed per type, and **only the first
+broken app per hour reached the operator** — measured 2026-08-23: `bookstack` sent at 09:27:51,
+`privatebin` suppressed at 09:31:51 under `key=demo-hp:app_start_failed`.
+
+**The mechanism is a named ALLOW-LIST (`perAppCooldownEvents`), not a payload rule**, and the
+distinction is load-bearing rather than stylistic: **`crossdrive_failed` is severity `error`, reaches
+the operator leg, and carries `stack_name`** through `CrossDriveDetails`. A rule of the form "if the
+details carry a stack_name, split per app" would have split it, silently, and undone R-182.
+`cooldownStackSuffix` therefore takes the **event type** as well as the details — an asymmetry with
+its two siblings, and the reason for it is exactly this.
+
+**Fenced act:** adding an entry to `perAppCooldownEvents` for a type whose family has a digest, or
+whose coarse cooldown is deliberate. Reading the register anywhere is fine.
+
+**Measured burst, so the volume is a number and not an impression:** three apps stopped in one scan
+produced **three attempted, three sent, zero suppressed** (2026-08-23). The reference box has 8
+deployed apps, so a total outage is 8 mails. The boot grace (90 s), the quiesce grace (180 s) and the
+per-app edge trigger absorb reboots, backup cycles and persistently-dead apps. **This scales linearly
+with app count and has no ceiling** — the condition that would reopen the question is a box large
+enough that a total outage is unreadable, at which point the answer is a digest with a customer
+message, not a wider cooldown.
+
+---
+
+## 7. The intent test [DESIGN, R-386 — CLOSED controller v0.223.0]
+
+**"The customer stopped this" is asked of the FIELD THAT RECORDS IT, never inferred from the state.**
+
+Until v0.223.0 `classifyRunStates` read `st.State == StateStopped` and assumed every stopped stack was
+deliberate. It is not inferable: `aggregateState` folds `StateExited` into the stopped counter, so an
+all-down stack returns `StateStopped` whatever killed it. Measured on `demo-hp` 2026-08-23:
+`privatebin` stopped out of band, nine dead-app scans over four minutes, **zero events, zero banner
+lines** — while a comment beside the code claimed an out-of-band stop *"still alerts"*.
+
+`DesiredState` records the answer, has **exactly one writer** (the customer's own action), and is
+tri-state:
+
+| Intent | Verdict | Why |
+|---|---|---|
+| `Stopped` | **no alarm** | the customer asked |
+| `Running` | **ALARM** | nobody asked — the R-386 case |
+| absent (`""`) | **no alarm, and SAY SO** | UNKNOWN never means running |
+
+**The absent case keeps the old behaviour deliberately.** Reading it as "nobody asked" would, on the
+first cycle after upgrade, e-mail about every app any owner ever stopped — fleet-wide, from a field
+that predates the intent being asked of it. The backfill cannot help: it seeds `Running` only from an
+observed-**up** reading, so anything stopped at upgrade time stays unknown, which is precisely the
+ambiguous population.
+
+**The gap is BOUNDED, not silent.** Every such suppression sets `AppRunState.IntentUnknown`, and the
+scheduler logs the names at `INFO` on the heartbeat cadence:
+
+```
+[deadapp] N stopped app(s) have NO recorded customer intent, so their dead-app alarm is
+suppressed by the unknown-intent fallback (R-386): <names>. This closes itself as each app is
+started or stopped through the interface.
+```
+
+**A rule without a mechanism is a wish.** Measured on `demo-hp` 2026-08-23: **0 of 8 deployed apps had
+an absent intent** — the population is already empty on an exercised box; it will be larger on one
+upgraded and left alone.
+
+`failedRestart` still lifts a `Stopped` intent, and that ordering is load-bearing: the quiesce loop
+stops stacks by the same path a customer does, so one it stopped and could not restart must alarm
+whatever the intent says. Removing that term re-opens F-CRIT-1.
+
+**Fenced act:** adding a `DesiredState` **writer**. Reading it anywhere is fine. Twelve of
+`StopStack`'s fourteen callers are machines, so recording intent in the primitive would make a nightly
+backup indistinguishable from the customer pressing Stop.
+
+---
+
+## 8. Direction — who a customer should be notified about at all
+
+**[DESIGN — DIRECTION, NOT CURRENT BEHAVIOUR. Dated 2026-08-23, the operator's own framing.
+Nothing in controller v0.223.0 / hub v0.107.0 implements this.]**
+
+> **A customer should be notified only about things they can act on or are responsible for** — the
+> drive they unplugged, the storage they filled. **A failed backup is our incident, not theirs.** The
+> intended shape is that we detect it, we tell them we noticed and are dealing with it, and they are
+> not handed an error they cannot solve. The subscription should feel like being looked after, not
+> like being on call.
+
+Today's settings page is the opposite shape: it exposes one toggle per detector and **grew from 12 to
+15 in this session alone** (one new alarm, plus two compound toggles split into four). That growth is
+the argument, not an aside — a page that grows by one per detector is a page that will keep asking a
+household to make engineering decisions.
+
+`app_start_failed` defaulting **off** is consistent with this direction and reversible either way; it
+was ruled that way on its own merits and does not pre-judge the redesign.
+
+**Filed as a PRODUCT DECISION, not a defect** — see the register. It is the operator's call to take
+separately, and no part of it was implemented here.

+# 09 — How an app update works, and what it is becoming
+
+> **LIVING DOCUMENT. Every slice of the update arc updates this file in the same session.**
+> Opened 2026-09-02 with slices 1 and 2. Its absence was **R-438**: the update mechanism was chosen
+> deliberately and written down nowhere, which is how a deliberate design gets "fixed" by someone who
+> did not know it was one.
+
+**This file carries the REASONING. The register (`backlog/OPEN-ITEMS.md`) carries the work. The
+source is the truth.** Nothing here is invented: every mechanism claim is cited either to
+`audits/SPIKE-app-update-2026-09-01.md`, which measured it live, or to live source at `file:symbol`.
+
+---
+
+## 1. How an update works today, as measured
+
+### 1.1 The button
+
+`Manager.UpdateStack` (`felhom-controller/controller/internal/stacks/manager.go:1199`) is two compose
+commands and nothing else:
+
+```
+compose pull                       →  compose up -d --remove-orphans
+```
+
+**No safety copy. No rollback. No hold. No verification.** Confirmed by reading and across six live
+updates (spike §10 item 6). A pull FAILURE is handled correctly — `UpdateStack` returns after the
+failed pull and never reaches `up -d`, so the running app survives untouched (measured twice, spike
+§4 3a). A pull that succeeds over an image that then fails to RUN is the bad case, and it is R-443.
+
+### 1.2 The catalog syncer moves the file underneath a deployed app
+
+`Syncer.copyTemplates` (`felhom-controller/controller/internal/sync/sync.go:319`) copies
+`docker-compose.yml` and `.felhom.yml` into **every** stack folder on a 15-minute cycle
+(`internal/config/config.go:351`, default `15m`). **It has no deployed check of any kind.** Its only
+guard is a sha256 content compare in `copyIfChanged` (`sync.go:403`) and its only exclusion is
+`app.yaml`. The post-sync hook is `stackMgr.InjectMissingFields(updated)` and nothing else — **the
+sync does not restart anything.**
+
+That is why a deployed app's compose file and its running containers can disagree **indefinitely**.
+Measured live 2026-09-01: a real catalog pin change travelled the real cycle, the sync rewrote the
+deployed app's file at 17:45:17Z, and the container went on running the old image (spike §3).
+
+### 1.3 Thirteen other paths end in `compose up -d`
+
+Excluding the three API actions, **13 call sites across 9 files** call `StartStack` or `RestartStack`,
+and every one ends in `compose up -d` against the live compose file (spike §8 — the task that
+commissioned the spike said five; the count is thirteen). They include the **boot reconciler**
+(`bootrecon.go:269`), the **app-stop guard's** recovery (`appstop_marker.go:283`), the **drive-return
+gate** (`intermediary.go:222`), the quiesce restart-after-backup, off-site reconstitution, and every
+restore path.
+
+**So an upgrade can happen with nobody pressing anything** — measured, spike §2 variant 1c-ii, where
+a boot reconciliation started an app on a newer image at 17:55:44Z.
+
+### 1.4 One fear is measured SMALLER than it was stated
+
+A plain power cut does **not** upgrade anything. Docker's own `restart: unless-stopped` puts the
+existing containers back on the OLD image, so the boot reconciler finds no orphan and never runs
+`up -d` — it says so in its own words: `no boot-orphaned apps (nothing to start)` (spike §2, variant
+1c, a positive observable and not an absent log line).
+
+**The unattended upgrade needs the narrower precondition: *"and the app did not come back."*** Saying
+so is more useful than leaving the scarier version standing.
+
+---
+
+## 2. What was chosen, and by whom
+
+`Manager.RestartStack` (`internal/stacks/manager.go:1161`) carries this comment, and it predates the
+whole arc:
+
+> *"Use `up -d` instead of bare `restart` so that env vars from app.yaml are injected and any template
+> changes (new images, healthchecks) are picked up. Plain `docker compose restart` only sends
+> SIGTERM+start to existing containers without re-reading the compose file or env."*
+
+**So the restart behaviour was chosen, deliberately, and written down. A design decision is not a
+defect.** What was never decided — and is recorded nowhere — is what happens once the catalog syncer
+moves the file underneath a *deployed* app, and whether the choice was meant to extend to the thirteen
+unattended call sites. **That gap is R-438, and it stays open**: this document records the mechanism;
+it does not change it.
+
+---
+
+## 3. The operator decisions
+
+These are rulings, not proposals. Anything specced against a different assumption is wrong.
+
+### 2026-09-02
+
+1. **The safety copy is a verified recent backup as a PRECONDITION** — not a new copy invented for the
+   update path. The guest-snapshot alternative is to be **spiked before anything is designed around
+   it**. Context: the existing safety machinery (`Manager.writeSafetyDump`,
+   `internal/backup/offbox_reconstitute.go:207`) is **database-only**, which is the headline of spike
+   §6 — the file half was never priced, and demo-hp is too young a box to price it.
+
+2. **The support window runs on HOW FAR BEHIND THE CATALOG a box is, not on how old its version is.**
+   A customer on the newest version is supported however old that version is. This is why
+   `catalog_since` exists and why no version string is shown.
+
+3. **Updates are automatic WITHIN a major, never ACROSS one.** The cross-major case needs a human,
+   because §4 says it cannot be undone.
+
+### 2026-09-06 — **Option 1: freeze the version, keep the fixes flowing.** SHIPPED, v0.235.0
+
+4. **An app's version is frozen to what the customer has, and only a deliberate Update moves it —
+   while corrections to its definition keep arriving on the 15-minute cycle exactly as they do
+   today.**
+
+   **This is the ruling R-447 was blocked on**, and it was blocked for a good reason: §2 establishes
+   that `RestartStack`'s use of `up -d` to pick up template changes was **chosen** and written down in
+   its own comment. Reversing a chosen behaviour is a decision, not a bug fix.
+
+   **What the ruling looked at, and why it is not simply "stop the syncer touching deployed apps".**
+   The old behaviour had two halves and only one of them was unwanted:
+
+   | half | verdict |
+   |---|---|
+   | a restart/repair silently changes the app's VERSION | **unwanted** — nobody chose it, nobody is told, and §4 says it cannot be undone |
+   | template CORRECTIONS reach a deployed app, and a broken definition heals itself within 15 minutes | **worth keeping** — both measured in the spike §3 |
+
+   So the ruling keeps the second and removes the first. In the operator's own words: *while the
+   catalog is offering the same version you are running, its fixes flow to you; the moment it moves to
+   a newer version, you are frozen at what you have until you choose to update.*
+
+   **It does NOT make the Update button safer.** That is slice 4 (R-448), and it is where the backup
+   precondition goes. Slice 3 only stops the other twelve paths from doing the update's job.
+
+### 2026-09-13 — the database engine finishes its own conversion, and the upgrade test goes wide
+
+5. **DBs should be updated when the app moves, with proper precautions, tests and backoff plans**
+   — the operator's own words, ruling on `SPIKE-r459-mariadb-upgrade-2026-09-06.md`. SHIPPED in the
+   catalog the same day: every `mariadb:` sidecar (`bookstack-db`, `kimai-db`, `nextcloud-db`,
+   `romm-db`) carries `MARIADB_AUTO_UPGRADE=1`; `MARIADB_DISABLE_UPGRADE_BACKUP` stays unset. **Not an
+   image change, so `catalog_since` does not move.** The three precautions, because they are the real
+   content of the ruling:
+   1. **Proven before it ships** — `upgrade-test.py` re-ran E3 and E3b on the changed template and the
+      engine-state field shows the conversion RAN (`mariadb_upgrade_info` reads the new version, the
+      engine's own check says nothing further is needed, the entrypoint no longer prints
+      `skipped due to $MARIADB_AUTO_UPGRADE`), with the seeded data reading back after. C3 still
+      returns `failed`. Evidence: `audits/r459-close-2026-09-13/`.
+   2. **Watched as it lands** — the change travelled the real 15-minute cycle to demo-hp: the live
+      compose gained the setting, the sync recreated nothing, and one deliberate restart logged
+      `MariaDB upgrade not required` with the app serving (same evidence directory).
+   3. **A rule until Slice 4 is built** — the Update button still takes no backup, so **no template
+      may move a database-engine image across a major version until R-448 ships.** Catalog
+      `CLAUDE.md` states it; `scripts/check-engine-major.py` enforces it in the pre-push hook (the
+      CI half cannot, R-452); its removal is tracked as **R-469** so it is a deliberate act.
+   The setting is inert until an engine major moves, and precaution 3 keeps it that way.
+
+6. **The upgrade test goes as wide as possible, through the nightly unattended sessions** — the
+   ruling on `STATUS.md` item 11. Not "the ~25 database apps first": all of them, as the nightly
+   rotation reaches them, one fixture per app through the app's own interface. **Browser-only apps
+   become reachable when CC runs on the operator's Windows workstation with Chrome** — the
+   `claude-in-chrome` route that DooPlex does not have — so an app recorded `inconclusive` for want
+   of a headless seed route (bookstack's file half, R-460) is deferred to that venue, not faked.
+
+---
+
+### 2026-09-13 (afternoon) — the floor carries a release without a golden, and every backup counts
+
+7. **A floor carries a release past the vouched golden when the release's MinAgent is declared with
+   it** (R-472; hub v0.112.0). Inside the golden the manifest's MinAgent governs, as before. Above it,
+   the MinAgent the operator declares with the floor — read from the release's CHANGELOG header, which
+   `minagent_header_gate.py` now guarantees — goes into the same per-box agent comparison. An
+   undeclared floor above the golden is still HELD, and both floor forms refuse to save one. **Why:** a
+   controller image is pulled by tag and needs no golden to be delivered; what the floor was missing
+   was only the agent requirement. This is what lets the weekly golden cadence (R-468) and per-release
+   delivery coexist. **Proven live:** both demo boxes self-updated 0.238.1 → 0.239.0 in 14 s and 15 s
+   from the save, the hub logging `SERVED … from declared`
+   (`audits/rulings-r472-r475-2026-09-13/03-declared-floor.txt`).
+8. **Any backup tier lets an app update** (R-475; controller v0.239.0). The precondition takes the first
+   FRESH copy in the order second drive (Tier 2), the app's own recovery unit (Tier 1), off-site
+   (Tier 3, bounded; unreachable = absent). `update.backup_max_age` applies to whichever tier is chosen.
+   An app with nothing anywhere is backed up first; it is refused only when no backup can be taken
+   either. The hold names the tier and the date. **Tier 2 is required nowhere in the update path.**
+   This replaces decision 1's reading "the verified backup = the Tier-2 unit" — decision 1 itself (a
+   verified recent backup as a precondition, not a new copy) stands. **Proven live:**
+   `audits/rulings-r472-r475-2026-09-13/` 04 (nothing anywhere → backup first), 05 (Tier 1 alone),
+   07 (a failed update held naming „saját meghajtó"), 08 (restored from „helyi", hold cleared).
+
+9. **A bind-data app's route back is off-site before its own unit, and the hold says what the copy
+   holds** (R-479, controller v0.241.0). An app whose data is bind-mounted files has a recovery unit
+   that holds the definition and the database dumps and NOT the files (measured: gokapi restored from
+   „helyi" came back with settings and no data). For such an app the update walks second drive →
+   off-site → own unit; for an app whose data is in named volumes the v0.239.0 order (second drive →
+   own unit → off-site) stands. Either way the hold sentence ends with what the named copy holds, so a
+   customer is never sent to a copy that cannot bring the data back without being told so.
+
+## 4. The vocabulary ruling — "rollback" is struck
+
+**App data CANNOT be rolled back.** Measured on Nextcloud (spike §7): once a migration has actually
+run, putting the old image tag back produces a container that refuses to start —
+
+> *"the version of the data (32.0.9.2) is higher than the docker image version (31.0.14.1) and
+> downgrading is not supported"*
+
+with a positive control proving the data is intact, only unreachable by the old version (§7 6d).
+
+**So "rollback" must not appear in any spec for this arc.** The two shapes actually available are:
+
+| shape | when it applies | what it does |
+|---|---|---|
+| **ABORT** | before anything migrated | stop, put the old image back, the app runs again |
+| **RESTORE FROM A COPY** | after a migration ran | the data restore is the whole remedy |
+
+There is no third.
+
+### 4.1 MEASURED 2026-09-06 — and the abort turns out to be a property of the APP, not of upgrades
+
+`SPIKE-upgrade-test-2026-09-06.md` upgraded three real apps with real data in them and then attempted
+the abort on each. **All five real catalog upgrades kept the customer's data.** The abort did not
+behave the same way twice:
+
+| app | abort | why |
+|---|---|---|
+| **docmost** `0.25.3`→`0.95.0` | **REFUSES** | the old code finds migration ledger entries it does not know: *"corrupted migrations: previously executed migration 20260213T085259-notifications is missing"*, then *"Failed to run database migration. Exiting program."* |
+| **privatebin** `1.7.5`→`2.0.5` | **works** | file-backed, no database, no schema — a major version moves no data |
+| **bookstack** app+engine | **works, misleadingly** | only because the MariaDB datadir upgrade was skipped and never happened — see R-459 |
+
+**This puts TWO independent measurements behind the ruling above, by two unrelated mechanisms:**
+Nextcloud refused on an explicit version comparison; docmost refuses on its migration ledger. The word
+"rollback" was already struck; it is now struck on evidence rather than on one case.
+
+**And it adds a distinction this document did not have: there is no single answer to "can this update
+be undone". There are apps where it can and apps where it cannot, and the only way to know which is to
+MEASURE THAT APP.** Any design that assumes one answer for all 53 is designing against a fact that was
+checked and is false.
+
+Per §5 below, a restore's image-level undo used to have a ≤15-minute half-life because the syncer
+overwrote it (**R-441**) — closed in v0.235.0.
+
+---
+
+## 5. The shape, as SHIPPED in v0.235.0
+
+The live `docker-compose.yml` is **DERIVED** from a pin recorded in `app.yaml` — the one file the
+syncer never touches. The catalog proposes; `app.yaml` decides; the compose file is an output rather
+than an input, and the thirteen unattended `up -d` paths stop being able to change a version by
+accident.
+
+### 5.1 Nothing was added to the thirteen call sites, and that is deliberate
+
+**They are made safe by removing the reason, not by gating them.** The most important of them are
+REPAIRS — the boot reconciler (`bootrecon.go:269`), the drive-return gate (`intermediary.go:222`),
+the app-stop guard (`appstop_marker.go:283`). **A repair path that refuses to repair leaves a
+customer's app down, which is worse than the problem this slice solves.** Since the file they act on
+no longer changes version, every one of them became safe without being touched.
+
+### 5.2 The pin, and what it is not
+
+`AppConfig.PinnedImages` (`app.yaml`, `pinned_images:`), service → image ref.
+
+**It is NOT `InstalledImages`.** That field is an OBSERVATION — what containers report. This one is a
+DECISION — what should run. Letting an observation feed a decision would make a bad reading become a
+bad deployment, which is the category error `desired_state` exists to avoid (R-166), one field over.
+They will normally agree; when they disagree that is a signal, not a bug to paper over.
+
+**Absent means UNPINNED, and unpinned means the app behaves exactly as it did before v0.235.0.**
+
+Beside it, `applied-compose.yml` in the stack directory stores the exact definition that pin came
+from. `Syncer.copyTemplates` copies exactly `docker-compose.yml` and `.felhom.yml`, so that name is
+safe from the catalog, and keeping it beside the app means it travels with every path that already
+moves a stack dir.
+
+### 5.3 The four writers — the only acts entitled to move a version
+
+| writer | pin source |
+|---|---|
+| the deploy path (`runComposeDeploy`) | the template just deployed from |
+| **`UpdateStack`** | the catalog's current template, written **BEFORE** the pull |
+| the restore (`stackAdapter.RecreateStackDefinitionFromUnit`) | the recovery unit's captured compose — **this closes R-441** |
+| `Manager.AdoptPins` | the observation, once, and only when complete AND matching |
+
+**`UpdateStack`'s ordering is load-bearing, not stylistic.** `compose pull` and `up -d` act on the file
+on disk, so the catalog's definition has to BE that file before either runs. A pin set afterwards
+would pull the frozen version and change nothing — while reporting success, and a button that lies is
+worse than a button that refuses. **A failed pin write REFUSES the update**, which is the opposite of
+`recordInstalledImages` and for the same reason `desired_state` refuses: this field is intent.
+
+### 5.4 The render table, complete
+
+| app state | result |
+|---|---|
+| not deployed / protected / seam not wired | the catalog template — today's behaviour |
+| deployed, **unpinned** | the catalog template + one DEBUG |
+| deployed, pinned, catalog images **equal** | the catalog template — **fixes flow, self-healing works** |
+| deployed, pinned, catalog images **differ** | the **stored applied definition** — frozen WHOLE |
+| pinned, differ, nothing stored | the catalog template + one WARN. We cannot freeze what we do not have and must not invent it |
+| mid-deploy | the compose file is left alone this cycle |
+
+**`.felhom.yml` is copied verbatim in every case** — it carries no image, and it carries
+`catalog_since`, which the badge needs. See §8.5.
+
+**The frozen branch writes a WHOLE file and never a substitution.** Taking the new template and
+putting the old refs back creates a third state nobody chose: `wger 2.6` needs a full DB configuration
+the older template cannot supply, so an old image under a new template is broken in a way neither
+version is.
+
+**And this is not "skip deployed apps".** That option was considered and rejected: it also stops
+health-check fixes, memory limits and new deploy fields, and it destroys the self-healing measured in
+the spike §3 — both halves the ruling explicitly kept.
+
+### 5.5 Adoption, and why the startup order matters
+
+`AdoptPins` runs once at boot, immediately after `BackfillInstalledImages`, and pins every deployed app
+to what it is already running. **It reads and writes files only** — no container is started, stopped or
+touched. It skips, loudly, when the observation is incomplete or when the app runs something the
+current template no longer offers; those apps keep pre-v0.235.0 behaviour rather than receive a
+guessed pin.
+
+**`syncer.Start()` was moved to after adoption.** It fires an immediate sync; at its previous position
+that first sync ran while every app was still unpinned, copied the catalog over a deployed app, and
+handed the next restart a version change — the exact behaviour this slice removes, once per boot.
+
+### 5.6 The trap this slice set for the previous one
+
+`Stack.TemplateImages` is read from the app's **live** compose file — which is now the RENDERED one.
+On a frozen app that file names the OLD version, so `web.compareInstalledToTemplate` would find
+installed == template and answer **„Naprakész" on exactly the apps that are behind** — with every test
+still green, because the new field has the same type and shape. The badge now reads
+`Stack.CatalogImages`, taken from the syncer's own git clone. **A feature that silently inverts an
+earlier feature is the failure mode to look for whenever a file changes meaning.**
+
+---
+
+## 6. The seven slices
+
+| # | slice | status |
+|---|---|---|
+| **1** | **The box records what it actually installed** — `app.yaml.installed_images`, per compose service, ref + digest + first-seen. | **SHIPPED, controller v0.233.0 (2026-09-02)** |
+| **1b** | **Seed the record for apps nobody touches** — a startup backfill, so the label is not restricted to apps that happen to get restarted. | **SHIPPED, controller v0.234.0 (2026-09-03)** |
+| **2** | **One badge says whether the app is current** — „Naprakész" / „Frissítés elérhető — N napja", from `catalog_since`. No version number. | **SHIPPED, controller v0.233.0 + catalog `69761cf` (2026-09-02)** |
+| **3** | **The compose file becomes DERIVED** — the pin in `app.yaml` wins; the syncer renders instead of copying. | **SHIPPED, controller v0.235.0 (2026-09-06)** — operator ruling §3.4 |
+| **4** | **A guarded update** — verified-backup precondition, abort-on-failure, and the truth at the moment of action rather than 5m16s later (R-443). | **SHIPPED + PROVEN LIVE, controller v0.237.0 (job) + v0.238.0 (page) + v0.238.1 (2026-09-13); any backup tier since v0.239.0 (§3 decision 8)** — §6.1 |
+| **5** | **An upgrade test that runs again** — a harness that upgrades a real app with real data in it and asks the app for the data back. | **SHIPPED, `app-catalog/scripts/upgrade-test.py` (2026-09-06)** — 7 edges, 3 apps; see §4.1 and §10 |
+| **6** | **A version sequence** — updates automatic within a major, a human across one; **an engine change gets its own edge.** | OPEN — R-450 |
+| **7** | **A fleet sweep pipeline** — the operator can see, and move, how far behind every box is. | OPEN — R-451 |
+
+### 6.1 Slice 4 as SHIPPED (controller v0.237.0 + v0.238.0, 2026-09-13)
+
+`POST /api/stacks/{name}/update` is a guarded job. It answers **202** at once; the outcome exists only
+on `GET /api/stacks/{name}` (`updating`, `update_phase`, `update_phase_label`, `update_error`,
+`hold_reason`), and `update_phase=done` is written only after the app's health is known. **R-443 is
+closed by construction: nothing reports an update complete on the compose exit code.**
+
+**The sequence, and the order is the design:**
+
+| # | phase | what happens | on failure |
+|---|---|---|---|
+| 0 | refusals (409, before the intent is recorded) | held (R-439), busy (backup/restore/app-data op/quiesce), migration, already updating, deploying, memory (the deploy's `memoryVerdict`, releasing the app's own request), disk (**fixed 2 GB floor** — image size unknown without a registry), **no copy on ANY tier and no backup can be taken now** (since v0.239.0; before it, no restorable Tier-2 copy) | nothing moves, nothing is recorded |
+| 1 | `checking` | walks Tier 2 → Tier 1 → Tier 3 for the first copy younger than `update.backup_max_age` (v0.239.0) | nothing moves |
+| 2 | `backing-up` — only when no tier holds a fresh copy | `RunAppBackupNow`: this app's DB dump → volume dump → unit capture (marked proven current) → Tier-2 copy, whose failure is a WARN since v0.239.0 | refused with the backup's own error; nothing moves |
+| 3 | `safety-dump` | `WriteUpdateSafetyDump` (R-361's undo copy) — **before the pin moves** | refused; nothing moves |
+| 4 | `pinning` | the previous definition is copied aside and journaled, then the pin advances | pin put back |
+| 5 | `pulling` | `compose pull` | **pin and definition PUT BACK** — nothing ran (Scenario E) |
+| 6 | `starting` | `compose up -d --remove-orphans` | stop + HOLD |
+| 7 | `verifying` | the `.felhom.yml` health check through the existing probe, or 60 s of every container running and none restarting; bounded by `update.health_timeout` | **stop + HOLD; the pin STAYS** — the migration may have run (Scenario F) |
+| 8 | `done` | installed images recorded, journal cleared | — |
+
+**The two knobs** (`controller.yaml`, operator-owned): `update.backup_max_age` (default `24h`) and
+`update.health_timeout` (default `5m`).
+
+**The precondition is the existing verified backup, not a new copy** (§3 decision 1). It is
+`backup.Tier2UnitRestorePoint` — the SAME predicate that permits the destructive „Teljes
+visszaállítás", extracted from the backups page rather than copied. **The copy is aged by the last
+SUCCESSFUL Tier-2 copy, not by the unit manifest's `created_at`**, and that was measured before it was
+designed: a capture rewrites the manifest only when the app's DEFINITION changes, so on demo-hp
+bookstack's mirror held a 2026-09-13T00:30Z dump under a manifest dated 2026-09-12T02:15:29Z. Aged by the
+manifest, a quiet app would be "stale" forever and a backup-first would not fix it. **The predicate is
+Tier-2-only, as specified — an app with no Tier-2 copy cannot be updated (R-475).** **SUPERSEDED in
+v0.239.0 by §3 decision 8:** `backup.Manager.UpdateRestorePoints` walks all three tiers and the update
+leans on the first fresh copy; `Tier2UnitRestorePoint` is still the Tier-2 half and still the page's
+predicate for „Teljes visszaállítás". The same aging trap existed one tier down — a capture's checksum
+skip leaves a quiet app's unit manifest untouched — so "back up first" now marks the captured unit
+proven current. The hold stores `copy_tier` and names „második meghajtó" / „saját meghajtó" /
+„távoli mentés"; a successful off-site restore now lifts an update hold too.
+
+**The hold** is `settings.RestoreHold` with `reason: update_failed` and `copy_date` — the SAME store and
+gate as R-379, so every start path that already honoured a restore hold honours this one. A successful
+unit restore lifts an update hold (only that kind). **Three unattended paths honoured no hold before
+v0.237.0 and now do:** the drive-return gate's restart and boot recreate, and the nightly volume dump
+(which ends in `StartStack`). The nightly capture and Tier-2 run skip a held app, so the restore point
+the hold text names is never overwritten.
+
+**Crash safety is a journal**, `<data>/update-journal.json`, written before every phase. `RecoverUpdates`
+runs before the boot sweep: interrupted before the pin → dropped; while pinning/pulling → pin put back;
+after `up` → marked Updating (the boot sweep and the dead-app alarm leave it alone) and resumed by
+`ResumeInterruptedUpdates` once the backup side is wired, ending healthy or held.
+
+**THE ABORT DECISION, restated so it is not reopened: NOT BUILT, BY MEASUREMENT.** Whether an old image
+starts on data a new one migrated is per-app (§4.1: PrivateBin yes, Docmost and Nextcloud no) and cannot
+be predicted. So the box never puts the old version back by itself. **The route back is the restore**,
+and slice 4's whole purpose is that the restore exists before anything moves. Per-app abort data, where
+the harness has proven it, is slice 6's.
+
+**Not gated here:** a multi-major jump (R-40). It fails health and is held honestly; stepping is slice 6.
+
+**The release could not reach the fleet by floor — R-472.** The hub holds a controller floor above the
+vouched golden (publish-train rule 1), so under the weekly golden cadence (R-468) v0.237.0 and v0.238.0
+were hand-deployed to the demo guests. **RESOLVED by §3 decision 7 (hub v0.112.0):** v0.239.0 reached
+both demo boxes by the floor alone, with its MinAgent declared.
+
+**Found live, fixed in v0.238.1: the nightly legs must leave an app alone WHILE it is updating, not
+only once it is held.** In Scenario F the periodic unit capture ran at 10:17:09 — inside the 5-minute
+health wait, 53 s before the hold — and wrote the never-started definition into the app's PRIMARY unit.
+The Tier-2 mirror the hold names survived only because Tier 2 is daily. `backup.Manager.isHeld` now also
+answers true for an app a guarded update is moving (`SetUpdatingCheck`).
+
+**v0.240.0 (2026-09-13, evening) — what the afternoon's proof and the first nightly rotation found, fixed.**
+Seven rows: removal with backups kept now keeps the Tier-2 RECORD, so the second-drive restore is not
+refused over an intact mirror (R-486, P1 — the disaster the second copy exists for); PostGIS/pgvector/
+TimescaleDB images are Postgres, so such apps get their logical dump (R-484); "delete backups" deletes
+the unit, the mirror(s) and the prefs (R-474/R-466); the backup card sizes them (R-485); a held
+update's sentence leaves the card with the hold (R-480); the Tier-3 lookup is one `snapshots` call
+(R-477); a unit older than the app's `deployed_at` does not count (R-478). Delivered by the floor in
+16 s / 18 s; every row proven live with a throwaway adventurelog. `audits/v0240-2026-09-13/`.
+
+**Proven live on demo-hp, 2026-09-13**, with a throwaway uptime-kuma and real catalog tag changes (each
+reverted in the same phase): A (2.3.2→2.4.0, done after health), B (`backup_max_age: 2m` → backup first),
+E (non-existent tag → pin back, container untouched), F (`alpine:3.20` → held), H (three buttons and the
+boot sweep refuse the held app), and the restore walk (Mentések unit restore → back on 2.4.0, hold
+cleared). Live evidence: `audits/slice4-2026-09-13/`.
+
+### The verdict record — the contract Slice 6 carries
+
+Decided here rather than invented twice. The harness writes one of these per edge, beside its
+evidence; Slice 6 puts the same shape in the catalog.
+
+```json
+{"harness_version": 1, "app": "bookstack",
+ "from": {"bookstack": "…:25.02.2", "bookstack-db": "mariadb:11.6"},
+ "to":   {"bookstack": "…:26.05.2", "bookstack-db": "mariadb:12.3"},
+ "verdict": "proven | failed | inconclusive",
+ "seed_read_before": true, "seed_read_after": true, "healthy_after": true,

+ "abort_detail": "the refusal quoted verbatim, or null",
+ "duration_s": 0, "measured_at": "RFC3339", "evidence": "relative path"}
+```
+
+**`inconclusive` is a first-class verdict and must never be collapsed into `failed`.** "We could not
+measure it" and "it does not work" are different facts, and only one of them is about the app.
+**`migration_observed` is a quoted line, never an inference from timing** — the value of both the
+Nextcloud and the docmost findings was the exact sentence the app printed.
+
+### Database engines under an upgrade — MEASURED 2026-09-06
+
+**The arc's standing rule that an engine change gets its OWN edge now has measured evidence behind
+it**, and the evidence is stronger than the rule's original argument. The rule was justified by
+*"two migrations behind one edge is an unreadable failure when it breaks"* — a readability argument.
+What was measured is that **an engine change can be applied and silently NOT happen**, which the
+app-half edge cannot produce and which no amount of readability would have surfaced:
+
+- `SPIKE-upgrade-test-2026-09-06.md` §4 — MariaDB 12.3 starts on an 11.6 datadir, logs that the
+  conversion it requires was **skipped**, and serves. **Assigned to the engine half by decomposition:**
+  the app half alone produces no such line.
+- `SPIKE-r459-mariadb-upgrade-2026-09-06.md` — it is **stable but never self-resolving** (5 of 5
+  restarts, no degradation, and the engine says `Check required!` every time, forever). Converting
+  properly **succeeds**, costs **7 s**, takes its own system-database backup, and **does not** cost the
+  ability to abort. **The trade that was expected here does not exist.**
+- **2026-09-13 — the setting is in the catalog.** All four `mariadb:` sidecars carry
+  `MARIADB_AUTO_UPGRADE=1` (operator ruling, §3 decision 5), and `upgrade-test.py`'s engine-state field
+  now shows the conversion RUNNING on the bookstack edges. **And a gate holds the engines inside their
+  major until Slice 4:** `app-catalog-felhom.eu/scripts/check-engine-major.py` (R-469).
+
+**Two rules for anything this arc builds around a database engine:**
+
+1. **Ask the engine, not the log.** MariaDB's entrypoint prints `MariaDB upgrade not required` on an
+   unsupported **downgrade**; `mariadb-upgrade --check-if-upgrade-is-needed` names it exactly
+   (**R-464**). A cheap instrument built on the log line would report "fine" for the broken case.
+2. **The two engines fail in opposite directions, so one check will not do.** MariaDB starts anyway
+   and skips quietly; **PostgreSQL refuses to start** on a datadir from an older major, and the image
+   performs no `pg_upgrade`. Eleven templates carry PostgreSQL and **eight sit on `postgres:16-alpine`**
+   (**R-463**).
+
+**And an engine-state field belongs BESIDE a verdict, never inside it.** `upgrade-test.py` reports
+`engine_state_after` next to `verdict`, because an unconverted datadir is not *known* to be a failure
+and a verdict that said so would encode an unproven judgement.
+
+**The rule slice 6 inherits, recorded now while it is cheap:** an engine change gets its own edge,
+never bundled with an app version bump. `bookstack` moved the application *and* MariaDB 11.6 → 12.3 in
+one commit (`0b73e5e`); that is two migrations behind one edge, and an unreadable failure when it
+breaks.
+

+
+## 7. What slices 1 and 2 actually built
+
+### 7.1 The record (slice 1)
+
+`Manager.recordInstalledImages` (`felhom-controller/controller/internal/stacks/installed.go`) runs
+after a successful compose up from `StartStack`, `RestartStack`, `UpdateStack` and `runComposeDeploy`,
+and writes `app.yaml`:
+
+```yaml

+```
+
+Three rules, each with its reason:
+
+- **It reads the CONTAINER, never `docker-compose.yml`.** §1.2 is why: that file is the value that has
+  already moved. A record built from it would answer "what will happen next time something runs
+  `up -d`", which is a different question.
+- **A failed write NEVER refuses the action** — deliberately the opposite of `SetDesiredState`.
+  Intent refused, observation logged. Refusing to start a customer's app because we could not write
+  down which version it is trades a real outage for a bookkeeping gap.
+- **It is NOT called from `StartStackServices`** — the R-47 DB-only restore window would overwrite a
+  complete record with a partial one.
+
+**Seeded at startup (v0.234.0).** `Manager.BackfillInstalledImages` runs once at boot, beside the
+desired-state backfill and before the boot reconciler, and records what every deployed app is ALREADY
+on. It only READS containers. **This was not a refinement — without it the feature did not reach a
+quiet box at all:** see §8.3, which was written as a known limitation on 2026-09-02 and was a defect
+by the next morning.
+
+Two admission rules, and the second is the design:
+
+- **It never overwrites an existing record.** The bring-up paths own updates; this fills gaps only.
+- **It refuses to seed a PARTIAL observation.** §7.2's comparison reads a service-count mismatch as
+  BEHIND, so a degraded or crash-looping app seeded from its visible containers would render
+  „Frissítés elérhető" over an app that is perfectly current. The bring-up paths may write a partial
+  because they follow a SUCCESSFUL `up -d`, where a gap is real news and is logged; a backfill meets a
+  box in whatever state it is in. **Same field, two writers, two different admission rules — that is
+  deliberate and must not be "made consistent".**
+
+**Nothing reads it to take a decision.** Slice 2 reads it to render a label.
+
+### 7.2 The label (slice 2)
+
+`web.updateBadge` (`internal/web/updatebadge.go`) compares the recorded reference per service against
+what the current template pins, and renders through the existing `meta_badge` partial — no new markup,
+no new CSS.
+
+**Absent means UNKNOWN and never means current.** Every `app.yaml` written before v0.233.0 has no
+record, so a fall-through to „Naprakész" would have told the whole fleet their months-old apps were
+current. This is the R-166 lesson applied to an observation instead of an intent, and it is pinned by
+a test with a companion red-proof.
+
+**No version number reaches the customer** (operator ruling: a household cannot act on `26.05.2`).
+Version strings stay in the logs, the API and the hub.
+
+---
+
+## 8. Known limitations, stated plainly
+
+1. **„Naprakész" can be FALSE for the 23 floating pins.** The comparison is reference-to-reference and
+   queries no registry — a customer's box must not depend on reaching eight upstream registries to
+   render a page. For `postgres:16-alpine`, `mariadb:11.6` and 21 others the reference can be
+   identical while the image behind it has moved. **Measured, not theorised:** spike §5 found
+   `mariadb:11.4` and `mariadb:12.3` had both already moved upstream, with two fully-pinned controls
+   holding. Digest-level comparison needs a registry query and is deferred — **R-446**.
+2. **~~Nothing enforces `catalog_since`.~~ Enforced by the pre-push hook since 2026-09-13 (R-452, `app-catalog-felhom.eu/scripts/check-catalog-since.py`); CI's shallow clone still skips it out loud.** A commit that moves an `image:` line and forgets the date
+   under-reports how far behind a box is. The gates runner fetches at `--depth 1` and has no parent
+   commit to diff against, so the gate needs a deeper fetch — **R-452**.
+3. ~~**The record only appears after the next lifecycle action.**~~ **CLOSED in v0.234.0, and the way
+   it closed is worth keeping.** This was written on 2026-09-02 as an accepted limitation — *"the
+   fleet view fills in gradually"*. The operator looked at demo-felhom the next morning and found
+   OpenGist, up 15 hours, running exactly the catalog pin, showing **nothing at all**. **On a quiet
+   box "gradually" means "never", and a feature that fills itself in on an event nobody triggers is,
+   on the quiet installations, not shipped.** `BackfillInstalledImages` now seeds the absences at
+   startup by reading containers (§7.1). **The residue that stays:** the seed happens at controller
+   START, so a box between upgrade and its next restart still shows nothing — bounded by one restart
+   rather than unbounded.
+4. **A frozen app is frozen WHOLE.** While the catalog is ahead, **no** template correction reaches
+   that app — not even one unrelated to the version. That is the direct consequence of §3.4 and of the
+   `wger 2.6` hazard, and it is the right trade: a new template around an old image is a third broken
+   state. Recorded so it is a choice, not a surprise.
+5. **`.felhom.yml` keeps flowing while the compose file is frozen** — the deliberate asymmetry in
+   §5.4. So a frozen app can receive a health check written for a NEWER version and read as degraded.
+   **The failure direction is a false alarm, never data loss**, and freezing `.felhom.yml` would break
+   the update badge by withholding `catalog_since`. **R-458.**
+6. ~~**The Update button is still unguarded.**~~ **CLOSED 2026-09-13 by slice 4 (v0.237.0, §6.1).** It
+   refuses without a restorable, proven Tier-2 copy, backs up first when that copy is stale, takes a
+   safety dump, and holds an app that does not come up. **What stays true:** it still has no automatic
+   rollback (deliberately, §6.1) and can still attempt a multi-major jump the app will refuse (R-40) —
+   that now ends HELD rather than crash-looping behind a green button.
+7. ~~**An engine major can be applied without its datadir upgrade, and nothing notices.**~~ **CLOSED
+   2026-09-13 for MariaDB (R-459):** every `mariadb:` sidecar carries `MARIADB_AUTO_UPGRADE=1`, and the
+   harness shows the conversion running on the E3/E3b edges (§3 decision 5). **What stays true:** the
+   PostgreSQL half (R-463) has no equivalent — the image performs no `pg_upgrade` — and the
+   engine-major rule (§3 precaution 3, R-469) is what keeps both engines inside their major until
+   Slice 4 gives the Update button a backup.
+8. **Only three of 53 apps have ever had an upgrade measured**, and one of them (bookstack) can only
+   be half-proven headlessly (**R-460**). The widening is **R-462**, costed with real numbers.
+9. **The hub does not record image tags at all.** Its report's container payload carries name, state,
+   CPU and memory, and no image field (spike §5). So the fleet view of §6 slice 7 needs a hub-side
+   change; it is not derivable from what is already reported.
+

+> Opened 2026-09-17 by the localisation starter, AFTER its spike ran (controller v0.247.0). Before it,
+> no architecture document mentioned localisation at all (a grep of `architecture/*.md` for
+> `i18n|locali|language` found one incidental line in 07).

+
+**This file carries the REASONING. The register (`backlog/OPEN-ITEMS.md`, R-553..R-562) carries the
+work. The numbers are in `audits/I18N-INVENTORY-2026-09-17.md`. The source is the truth.**
+
+---
+
+## 1. The rule that makes this safe
+
+**[DESIGN] The Hungarian product must render byte-for-byte the same before and after every slice —
+measured page by page, never by reading.** A household that never switches must not be able to tell a
+localisation release happened. English goes on top of an unchanged Hungarian product.
+
+**[FACT]** It is enforceable, and enforced for the three converted pages: `TestI18nParity`
+(`felhom-controller/controller/internal/web/i18n_parity_test.go`) renders 14 fixture states of the
+launcher, `/backups` and `/apps/<slug>` in Hungarian and compares them with HTML captured from a clean
+worktree of `origin/main` 89dd3e94b1de **before** any template carried a marker. One changed byte in
+`hu.json` fails it naming the page and the line (red-proof,
+`felhom-controller/REPORT.md`). **Fixtures are captured from unconverted templates and never
+regenerated to make a conversion pass** — that is the release gate for every slice.
+
+The one normalisation: relative ages („3 napja") become „# napja", because they come from the wall
+clock.
+
+**[FACT] And live, on demo-hp guest 9201 (2026-09-17, endpoint-level):** the launcher, `/backups` and
+`/apps/privatebin` fetched in Hungarian on 0.246.0 and again on 0.247.0 are **identical apart from the
+version string and the CSRF token**, with equal raw byte counts (44 462 / 46 250 / 42 081), and again
+after a round trip through English (`audits/i18n-2026-09-17/live/`).
+
+---
+
+## 2. The mechanism, as measured
+
+### 2.1 What was chosen, and why
+
+**[DESIGN] A flat message bundle per language, expanded into the template BEFORE `html/template`
+parses it.** Decided by CC in the spike (the starter delegated the choice, §4 1.1 of the task).
+
+| option | cost | verdict |
+|---|---|---|
+| (a) `golang.org/x/text/message` catalogs + a `T` func | a new external dependency; its value is gender/plural/ordinal selection | **not needed**: the inventory found no gender agreement and only count plurals; Hungarian does not inflect after a numeral |
+| (b1) flat bundle, **runtime** `T` template func | every string passes through the contextual escaper: `+`, `'`, `"` change bytes; inside `<script>` a string becomes a quoted JS literal — 618 of the 1 867 template strings are in `<script>` | **rejected**: breaks byte parity by construction |
+| **(b2) flat bundle, expanded at template LOAD** | one parsed template set per language (startup parses every template once per language — not measured); a translation is raw source text, so its context safety must be tested | **chosen**: the Hungarian set is parsed from the same bytes, in the same escaping contexts — parity holds by construction and is then measured |
+
+### 2.2 How it works
+
+- **[FACT]** Bundles: `controller/internal/i18n/locales/hu.json` (authoritative — every key) and
+  `en.json`, embedded (`internal/i18n/i18n.go`). Flat `key → text`. A value may carry **template
+  actions** (`{{.RecoveryAbandonDate}}`) and **inline markup** (`<strong>`, `<a>`): those are the
+  message's parameters, kept inside one message so a translator can move them. English plurals are
+  `key.one` / `key.other` (`Bundle.Plural`), and a template value may also branch
+  (`{{if eq $n 1}}file{{else}}files{{end}}`).
+- **[FACT]** A converted template carries `{{T "key"}}`. `Server.loadTemplates` parses one set per
+  supported language through `parseTemplateSet` = `ParseFS` + `i18n.Expand` per file, naming templates
+  exactly as `ParseFS` does. `s.tmpl` stays the Hungarian set, so every renderer that predates i18n is
+  unchanged.
+- **[FACT]** An **undefined** key is left in place, so the set fails to load („function T not
+  defined") — loud at startup and in every render test (`TestExpandLeavesUndefinedMarker`).
+- **[FACT]** `executeTemplate` renders dashboard pages in the request's language. Since slice 1
+  (v0.249.0 recovery, v0.250.0 the rest) the pages outside the dashboard chrome — login, claim,
+  recovery, both guest share pages, the catch-all — render through `executeTemplateLang`: the language
+  set and `Lang`, and deliberately NOT the session CSRF fields or the escrow reminder (R-543) that
+  `executeTemplate` adds. Pinned by `TestDirectRenderHandlersFollowLanguage` (the real routes) and
+  `TestI18nDirectRenderPagesHaveNoAdminChrome` (reminder genuinely due, absent from the page data of all
+  six and from the guest page in both languages). No renderer uses `s.tmpl` directly any more.
+- **[FACT]** Go-side copy on a converted page: the handler names its title key (`data["TitleKey"]`;
+  `TestHandlerTitleKeysMatchHungarianTitle` pins each handler's Hungarian literal equal to its hu.json
+  value); the non-Hungarian sets override the copy-producing funcs `stateLabel`, `timeAgo`, `timeAgoStr`,
+  `nextRunLabel`, `statusText`, `infraMeta` from the bundle (`web/i18n_web.go` `localeFuncs`). The Hungarian funcs
+  are not touched; `TestLocaleFuncsHungarianBundleMatchesFuncMap` pins that `hu.json` carries the same
+  words they return.
+
+### 2.3 What a translation must not do (pinned by tests)
+
+- **Carry different parameters.** Same `{{.Field}}` set and same printf verbs as the Hungarian
+  (`TestBundleParametersMatchAcrossLanguages`).
+- **Break its context.** Expansion is textual; inside a JS string a bare `'`/`"`/`\` or newline ends
+  it, inside a double-quoted attribute a `"` ends it — and `html/template` cannot see this, because it
+  reads the expansion as the author's own source. A value may carry a quote only where the Hungarian
+  carries the same one (`TestI18nJSContextValuesAreSafe`, red-proofed with `Copied'`). English
+  therefore avoids apostrophes in JS contexts („do not", not „don't"); elsewhere it uses ’.
+- **Render blank or raw.** No raw key, no marker, no element empty in English that is not empty in
+  Hungarian (`TestI18nEnglishPages`).
+
+**[FACT] What stays Hungarian on the English pages, live (v0.250.0, all 31 slice-1 templates converted):**
+Go view-model text (flash lines, errors, the backup-target banner and offer, the whole-guest tier
+labels, the update badge „Naprakész", the catch-all's status sentence), three page titles built in Go
+around an app name (logs, deploy, tier-2 settings — R-566), and catalog copy (tagline, use cases, first
+steps) — slices 2 and 5. Deliberately left in a template: „Fut…" on `backups_remote`, which the page's
+own JS reads (R-563). Evidence: `audits/i18n-slice1-2026-09-17/{A,B,C}/live/`.
+
+**[FACT] Measured limits of the English page test.** (1) It subtracts fixture DATA strings before
+looking for Hungarian; since slice 1 release A only data strings of ≥ 2 words or ≥ 12 characters are
+subtracted, so a one-word template title is no longer masked. (2) **It sees accented Hungarian only.**
+An ASCII-only Hungarian word left in a template („mp", „ db", „jelenlegi:", „FIGYELEM:", „, majd a(z)")
+passes it on the English page; release C found six such fragments by eye, none by a test (R-565).
+
+---
+
+## 3. Who picks the language, and how it flows
+
+**[DESIGN] Operator decision 2 (2026-09-17, agreed): the operator sets it per customer on the hub at
+creation (default Hungarian); the household can switch it on their dashboard; the box reports it so
+the hub's e-mails follow.**
+
+- **[FACT] Built in v0.247.0:** `settings.json` `language` (`hu`|`en`; empty reads `hu`,
+  `Settings.GetLanguage`); `POST /settings/language` (session CSRF like every form; `lang`, `back`;
+  redirect drops the query); `?lang=hu|en` per-request override, never persisted; the hub report's
+  `"language"` field, always present, set at all four report build sites in `cmd/controller/main.go`.
+- **[FACT] Live 2026-09-17 on demo-hp:** `POST /settings/language lang=en` → 302, `settings.json`
+  `"language": "en"`, the three pages English; the hub's stored reports read no field (0.246.0), `hu`,
+  `en` at 12:54:43Z, `hu` at 12:55:22Z after switching back; without `_csrf` → 403 and nothing changed
+  (`audits/i18n-2026-09-17/live/README.md`).
+- **[FACT] Slice 3 Part A, hub v0.118.0 (2026-09-18):** the hub READS the reported language and writes
+  the household's e-mails in it. `hub/internal/i18n` (79 keys, hu authoritative, hu fallback, missing
+  ceiling 0); 56 mail goldens captured from v0.117.0 BEFORE any string moved, and all 56 Hungarian
+  ones pass unchanged. `customerMessages`/`severityLabels` are derived from the bundle. Order: last
+  reported → `customer_configs.language` → `hu` (`Store.CustomerLanguage`). `message_customer` is
+  accepted on `POST /api/v1/event` for the box's own sentences. The bind page is per-language, with
+  `expired` pinned to Hungarian so the language cannot become the oracle the text refuses to be.
+  Full design: `05-hub-architecture.md` §15. **R-555 closed** — the `language` allowlist entry is out
+  of `wire_contract_gate.py` and the gate now checks the field for real.
+- **[DESIGN] Slice 3 Part A as planned — now built; the box half (Part B) is the remaining piece:** the hub stores a per-customer language, renders it into
+  `controller.yaml` next to `customer.id/name/domain/email` (`hub/internal/configgen/configgen.go`),
+  and the box uses it **only while the household has never chosen** (`settings.json` empty). The
+  household's own choice always wins; the hub's e-mails follow the language the box **reports**, which
+  is therefore the household's choice. The hub decodes the report with independent `json.Unmarshal`
+  calls and no `DisallowUnknownFields` (`hub/internal/api/handler.go` `handleReport`), so the field
+  was additive.
+
+**[DESIGN] Decided by CC in the spike — operator may reverse: the switch is SHOWN only on a page that
+is not Hungarian, or on a request carrying `?lang=`.** One answerable sentence: *should a Hungarian
+household see an English switch while only three pages are English?* Options: (1) show it to everyone
+now — cost: one click from a half-English dashboard, and every page but three keeps a Hungarian body;
+(2) hide it until slice 1 converts the remaining pages — cost: a household cannot discover English
+yet, which no household has asked for. **Chosen (2)**: it follows rule §1 (nothing visible changes)
+and is reversed by deleting one condition in `addLanguageData`. The way back from English is always on
+screen.
+
+**[FACT] SUPERSEDED 2026-09-17 by slice 1 release C (controller v0.250.0):** every template is converted,
+so the condition is deleted and the switch is on every dashboard page, in both languages. The 89
+layout parity fixtures were re-captured and each equals its predecessor plus exactly one switch form
+(`audits/i18n-slice1-2026-09-17/C/switch-fixture-diff.txt`); `TestLanguageSwitch_EndToEnd` pins that a
+Hungarian household with no `?lang=` sees it. Live on demo-hp: every Hungarian dashboard page equals
+its 0.249.0 fetch once the switch form is removed (live numbers aside); login, claim and the catch-all
+are unchanged. **A Hungarian household sees it only when the fleet floor reaches 0.250.0** — the
+operator's cadence (R-242/R-468); no floor was raised.
+
+---
+
+## 4. Fallback
+
+**[DESIGN] Operator decision 3 (2026-09-17, agreed): a missing English line shows the Hungarian one
+and is counted by a gate; a missing line never shows a key or an empty box.**
+
+- **[FACT]** `Bundle.Text` falls back to Hungarian and flags it; the loader logs
+  `i18n: en template set shows Hungarian for N markers`; `Bundle.Msg` of a key absent everywhere
+  returns the key (visible, never blank) and `TestBundleKeysUsedExistInHungarian` refuses to ship one.
+- **[FACT]** `controller/scripts/i18n_missing_gate.py` (in `controller_gates.py`, pre-push): keys exist,
+  no orphans, **the English gap is a ratchet** — `EN_MISSING_CEILING` (0 today) convicts above AND
+  below, so it can only be lowered deliberately. Raising it is a decision recorded here.
+
+---
+
+## 5. The gates, per language
+
+**[FACT] Found in the spike: moving copy out of the templates blinded four gates and staled one.**
+The retrieval-promise gate went red on STALE allowlist entries the moment the first page converted;
+the emoji, native-confirm and secret-in-markup gates silently stopped seeing the moved copy. The HEAD
+versions of the emoji and retrieval gates PASSED a planted emoji and a planted retrieval promise in the
+bundles. They now judge the page **as rendered in each language** (`controller/scripts/i18n_bundle.py`
+`read_template(path, lang)`); mojibake scans the bundles; decoys for each are in
+`controller/scripts/test_gate_decoys.py`.
+
+**[DESIGN] Voice, per language:**
+- **hu** — the product speaks in „te". The converted copy carries formal („ön") forms (R-516). They are
+  not fixed by a localisation release (§1), so the gate counts them against `HU_FORMAL_CEILING` as a
+  ratchet: a new one convicts, fixing one lowers the ceiling. The ceiling followed the conversion:
+  6 (spike) → 10 (release A) → 12 (release B) → **16** (release C). **[FACT] Measured limit:** the stem
+  list is short — on the release C pages it counts 4 formal forms, while a wider list („írja be",
+  „adja meg", „válassza", „biztosan eltávolítja", „engedélyezze", …) finds at least 22 keys (R-516).
+- **en** — second person, plain: no „please", no „kindly".
+
+**[FACT] The retrieval-promise gate scans English too** since slice 1 release A (`EN_PATTERNS`,
+`ALLOWLIST_EN`, decoys). Translating exposed that its Hungarian stems miss split verbs („állíthatók
+vissza") — R-564. The hub copy gate and the catalog have no language concept
+(`scripts/hub_copy_gate.py` stems end in a Hungarian character class; `catalog_gates.py` checks no copy).
+
+---
+
+## 6. Deliberately out
+
+- **[DESIGN] The hub's operator pages** — the operator reads them; they stay English (decision 1).
+- **[DESIGN] The first-boot wizard** (`controller/internal/setup/`, 8 pages, 95 strings) — out of scope
+  and obsolete (decision 4, 2026-09-17; `02-controller-module-map.md` L56). A household still reaches
+  it when bootstrap ingestion leaves `customer.id` empty (inventory §2.7). Its deletion is **R-554**.
+- **[FACT]** App containers' own UIs (Uptime Kuma, PrivateBin…) — not Felhom's copy (R-516 items 5-6).
+
+---
+
+## 7. The catalog's copy model
+
+**[DESIGN, proposed — slice 5 decides after seeing it work]** A sibling block per language inside
+`.felhom.yml`, not a sibling file:
+
+```yaml
+description: Titkosított jegyzetek…
+app_info:
+  first_steps: [...]
+i18n:
+  en:
+    description: Encrypted notes…
+    app_info:
+      first_steps: [...]
+```
+
+Why: one app's copy stays in one file a reviewer sees whole; the controller's `yaml.Unmarshal`
+ignores unknown keys (`internal/stacks/metadata.go` L317), so older controllers are unaffected; a
+missing English field falls back field by field. Cost: 835 strings, ~4 984 words; the catalog copy
+gates need an English rule. Read on privatebin, nextcloud and immich (inventory §2.5).
+
+---
+
+## 8. Dates, numbers, plurals — as found
+
+- **[FACT]** Plurals: 42 Go format strings with `%d` and 7 template runs with a numeric parameter
+  (inventory §2.2/2.1). Hungarian needs one form; English two.
+- **[FACT]** Dates: 10 layout literals in `internal/web` Go, 2 in templates that **disagree with each
+  other** (`2006. 01. 02. 15:04` vs `2006-01-02 15:04`), 25 more in the controller; 9 copy-producing
+  helpers (`timeAgo` „%d perce", `nextRunLabel` „ma"/„holnap", `pruneLabel` „vasárnap"…).
+- **[FACT]** Sizes print a decimal POINT (`%.1f GB`) — Hungarian convention is a comma. The Hungarian
+  pages are already un-Hungarian there; §1 keeps it that way until someone decides otherwise (R-562).
+- **[FACT]** Word order: 237 Go format strings and 111 concatenations; in templates, JS sentences split
+  around `+ name +` („Az alkalmazás (" + name + ") törölve lett.") — translatable but fragile.
+- **[FACT]** Flash messages travel **inside the redirect URL** (`?flash=<text>`) in the language of the
+  handler that redirected — slice 2 moves them to keys.
+
+---
+
+## 9. Compared, not shown — latent bugs a translation would trigger
+
+**[FACT] There were FIVE, and they are fixed (controller v0.251.0, R-553 + R-563, 2026-09-17).** Four
+in Go and one in a page script. Each producer now attaches a machine-readable signal and each decision
+reads that signal; every Hungarian sentence is byte-identical (pinned per producer), and the hub report
+is unchanged.
+
+| decision | read before | reads now |
+|---|---|---|
+| deploy HTTP status — `api.deployStatusFor` | „kötelező", „memória", "does not exist", "already deployed" | `stacks.ErrRequiredField`, `ErrPathMissing`, `ErrNotEnoughMemory` (400); `ErrAlreadyDeployed` (409) |
+| off-site failure class — `ClassifyOffsiteFailure` | „tárhelykeretet" | `backup.ErrOffsiteQuota` |
+| alert placement — `web/alerts.go` | „meghajtó" / „adattároló" in the warning | `monitor.WarnKindStorageNotSeparate`, carried in `HealthReport.WarningKinds` (internal; NOT on the wire) |
+| the stale off-site note — `offboxWarningDisplay` | „nincs mentésre jelölt alkalmazás" in the PERSISTED text | `settings.OffboxTarget.LastWarningKind` = `backup.OffboxWarnNoAppsSelected` |
+| the remote-backup poll — `backups_remote.html` | the displayed word „Fut" | `data-status="running"` on the status element (R-563) |
+
+**[DESIGN] The rule this establishes:** a text signature may remain ONLY where the text is not ours.
+The classifier's restic and ssh signatures stay, because that output is neither written nor translated
+here; every sentence this product writes is display, and a decision reads a signal beside it.
+`internal/util.KindErrorf` exists for exactly that: the same message bytes `fmt.Errorf` produced, plus
+a sentinel for `errors.Is` — never `fmt.Errorf("%w: …")`, which would prepend the sentinel's own text
+to the customer's sentence.
+
+**[FACT] One exception, with an end date:** a box upgraded to 0.251.0 carries the OLD persisted note
+with no kind until its next off-site run, so `offboxWarningDisplay` keeps the substring test for
+`kind == ""` only. **Slice 2 (R-557) must not translate that producer until R-570 closes.**
+
+**[FACT] Measured after the fix** (`audits/r553-2026-09-17/`): the inventory's comparison detector finds
+**no template compare** (was one) and no Go compare of ours — the two remaining hits are the known
+false positive (an `[INFO]` log line) and the deliberate legacy fallback above; planted decoys prove the
+detector still convicts. **What it does NOT cover:** four API handlers pick their status by matching
+ENGLISH internal words — the same shape, one language over, filed as R-569 rather than folded in here.

+## 10. The plan
+
+Costs are CC-hours, estimated from the spike (mechanism + three pages + layout + gates ≈ one working
+session). Each slice ends with the parity gate green for every page it touched.
+
+| slice | row | what | proves | cost |
+|---|---|---|---|---|
+| 0 (done) | — | mechanism, 3 pages + layout, setting, report field, gates | Hungarian unchanged by measurement; English reachable | spent |
+| 1 (done, v0.248.0–v0.250.0) | R-556 | the other 31 dashboard templates (~1 500 strings, 600 of them JS), parity fixtures per page; switch shown to everyone; English retrieval stems; the extractor's ASCII word list reviewed per page | the whole dashboard in English with Hungarian byte-identical | 12–16 h, three releases |
+| 2 (done, v0.252.0–v0.254.0) | R-557 | Go-side customer strings; flash-in-URL → keys; country names; alert texts; the 179 error messages; the saved notes; the globe | a page's server messages follow the language | **CLOSED 2026-09-18** |
+| 3 | R-558 | hub: per-customer language at creation; `configgen` renders it; `customerMessages` (39), the 5 lifecycle mails and the self-bind page in English; dispatcher reads the reported language | a household's e-mails arrive in its language | 6–8 h, one hub + one controller release |
+| 4 | R-559 | console banner (34 lines, console-font limits) and the download page | an English household meets English from the first boot screen (in scope — ruling 1b) | 4–6 h + an ISO train |
+| 5 | R-560 | catalog: §7 format, controller reads it, 835 strings / ~5 000 words, catalog copy gates per language | an app card, its settings and its first steps in English | 12–16 h |
+| 6 | R-561 | the volunteer guide in English (~1 600 words); **then a stranger's first hour in English**, the 2026-09-14 walk; closes R-516 against the inventory | a newcomer can set up and use a box in English | 6–8 h |
+
+### 10.1 Slice 2, as measured (release A, controller v0.252.0, 2026-09-18)
+
+**[FACT] The counts the plan carried were the inventory's, and they moved.** At slice 2's base commit
+`736f54b49610` there were **1 120** Hungarian Go literals, not 1 141; `handlers.go` 120 (not 121),
+`offbox_handlers.go` 70 (not 72), `storage_handlers.go` 45 (not 48), `api/router.go` 18 (not 19).
+Release A converted **226** of them and added 237 country keys.
+
+**[DESIGN] A flash is a KEY, because it is read by a different request than the one that wrote it.**
+`?flash=<key>&fa=<param>…`, built by `flashQuery`, resolved by `s.flashFrom`. A value the bundle does
+not know is shown **verbatim** — that is what keeps a link already in a customer's tab, a bookmark or
+a back-forward cache reading correctly, and it is the same rule that makes a hand-typed `?flash=`
+harmless (`TestFlashKeyRoundTrip`). The same shape one layer in: an **alert banner** is built by a
+background health cycle and read minutes later, so `Alert` carries `MessageKey` + `MessageArgs` and
+`GetAlerts(lang)` renders on the way out.
+
+**[DESIGN] Word order is Go's explicit argument index, not a second placeholder syntax.** The plan
+proposed a named-parameter (`{{.Name}}`) form for multi-parameter Go messages. English reorders with
+`%[2]s`, which `fmt` already understands, so the Hungarian value stays **the format string the code
+always had, byte for byte** — and that is precisely what the parity gate compares. A second syntax
+would have needed an exception in the measurement, which is the thing this slice cannot afford.
+`TestBundleParametersMatchAcrossLanguages` counts an indexed verb as one verb.
+
+**[FACT] Parity for Go copy is measured, not read.** `controller/scripts/i18n_go_parity.py` freezes
+every Go string literal at the base commit (**7 467**, `scripts/i18n_go_base.json`) and refuses a key
+whose Hungarian is not that text byte for byte — reworded, re-punctuated, split or joined.
+`scripts/i18n_go_keys.json` records what each key replaced (a string for one literal, an ordered list
+for a join, `{"inside": …}` for the three sites where the Hungarian was already URL-escaped inside a
+redirect target). In `controller_gates.py`; three decoys, each seen to convict.
+
+**[FACT] The gate found a live defect in its own first version — the R-565 class again.** The capture
+filtered literals through an ASCII-Hungarian word list and missed seven real ones („Naponta",
+„5 percenkent", „Eletjel (Heartbeat)", „Adatbazis mentes", „Biztonsagi mentes", „Mentes integritas",
+„Rendszer allapot"); the gate refused the keys citing them. **The filter is gone.** The index answers
+one question — *did the base commit contain this text?* — and an unfiltered index answers it for every
+string. **The lesson generalises: a word list is a list, and nobody knows which words are missing.**
+
+**[FACT] Two claims in the plan that live source disproved, both about the wire.**
+
+1. `cloudflare/countries.go` is **not** on the wire. `report/builder.go` carries country **codes**;
+   no name leaves the box, and `CountryName()` has no caller. The 237 names were therefore free to
+   translate, and are — at DISPLAY, in `api/geo.go`, re-sorted per language. The table stays: it
+   validates codes.
+2. The hub does **not** compose every customer mail from the event kind. `FormatCustomerEmail`
+   (`hub/internal/notify/templates.go` L167-210) uses `customerMessages[eventType]` when it has one
+   and **falls back to the controller's message when it has none**, appending it as „- Üzenet: %s"
+   whenever the two differ; several event types carry no entry precisely so the controller's sentence
+   IS the mail. So `notify/notifier.go`'s 31 messages are customer-facing text on the wire. The
+   verdict (do not translate them here) was right; the reason was not, and the reason is what slice 3
+   has to act on.
+
+**[DESIGN] On the wire = not translated, and now measurable.** `internal/monitor` and
+`internal/notify` carry wire goldens capturing those producers' exact bytes at the base commit. A
+later slice that translates one fails a test that prints both strings. R-558 is the row that unfreezes
+them, by teaching the hub which language to compose in.
+
+**[FACT] Still Hungarian after release A:** 894 literals — **176 of them `fmt.Errorf`/`errors.New`**
+(release B), the text a background run persists (release C), the R-570 producer, `handler_debug.go`
+(R-574), two copy-producing funcmap helpers (R-572) and the two channel-health banners (R-573).
+
+**[DESIGN] Persisted text (release C) — the plan's §16 option 1, its own stated default.** A note is
+written in the box's language **at the time it is written**, and a household that switches sees last
+night's note in the old language until the next run rewrites it. The alternative (store a code, render
+live) costs a dozen new persisted fields and a legacy path for each — the R-570 shape, a dozen times
+over. Recorded here when release C ships.
+
+### 10.2 Slice 2 release B — an error carries the key of the sentence it is (v0.253.0)
+
+**[DESIGN] An error is made where there is no language and printed where there is no key, so it
+carries the key across.** `util.MsgError(key, args…)` / `MsgErrorf(kind, key, args…)`. **All 179
+Hungarian error literals are converted; zero remain** (an ASCII-fragment search with a positive and a
+negative control, case-insensitively, plus an accented-letter search).
+
+Four properties, each one a different failure if it is missing:
+
+| property | the failure without it | pinned by |
+|---|---|---|
+| `Error()` is the Hungarian, byte for byte | 179 producers could not be converted until every printer was, in one commit | `TestMsgErrorKeepsKindAndHuText` |
+| `errors.Is` answers for the kind **and** a wrapped cause | `KindErrorf` returned the kind alone; a caller testing for the cause silently stops matching | `TestMsgErrorUnwrapsTheCauseToo` |
+| an error ARGUMENT renders recursively | „formázás sikertelen: %w" is a sentence wrapping a sentence; half of it would stay Hungarian | `TestErrTextRendersAWrappedMessageErrorToo` |
+| a FOREIGN error prints verbatim | restic, docker, ssh and the stdlib are not ours (§9's rule) | `TestErrTextFallsBackVerbatim` |
+
+**[DESIGN] Plurals are a BUNDLE rule, not a call-site flag.** *A key that carries `.one`/`.other`
+forms in a language is a plural key, and its FIRST parameter is the count* (`i18n.Bundle.form`).
+Hungarian never carries them, so a Hungarian render is unchanged at every count. One answerable
+sentence: *where does the fact that English needs two forms live?* Options: (1) a flag at every
+producer of every count message, in three packages — cost: the one somebody forgets reads „3 app is
+not running", with nothing to catch it; (2) the bundle. **Chosen (2)**: the bundle is where a
+translator works, and it needs no change at any call site. `.one`/`.other` become RESERVED suffixes —
+`TestNoOrdinaryKeyEndsInAPluralSuffix`, which caught a real collision (`alert.deadapp.one`) the day
+the rule landed.
+
+**[FACT] The parity gate has a blind spot, measured rather than reasoned (R-576).** The bulk
+converter silently dropped the continuation of a multi-line concatenation, damaging **7** producers —
+and `i18n_go_parity.py` stayed GREEN, because every surviving fragment WAS a byte-equal base-commit
+literal. Its question is *"is this text real?"*; it cannot ask *"did the call keep all of it?"*. Two
+BEHAVIOUR tests caught it, because they assert the sentence a customer reads. **A structural gate over
+the TEXT cannot see a defect in the CALL** — the general form, and the reason a rendered test is not
+made redundant by a gate.
+
+**[FACT] A second instrument defect, same session (recorded because the shape recurs).** The script
+counting what was left was case-sensitive, so it reported "0 error literals remain" while five did
+(„occ parancs sikertelen", „hub hiba", „OnlyOffice aldomain nem ismert" ×2). That is R-565's shape
+inside the measurement. Every "no Hungarian left" claim in this slice is made case-insensitively and
+with both controls.
+
+**[FACT] One gap release B could not close: R-575.** `memoryVerdict`'s soft overcommit WARNING is a
+string with no error to carry a key and no language where it is built, so it renders Hungarian on an
+English page. The copy is in the bundle; only the render is fixed. Named in the code, filed as a row.
+
+### 10.3 Slice 2 release C — the saved notes, and a globe (v0.254.0). SLICE 2 CLOSED.
+
+**[DESIGN] A note a background run SAVES is written in the BOX's language at write time** (operator
+ruling, §16 option 1). ~70 producers. **The consequence, recorded because it is the cost of the
+choice:** a household that switches language sees the previous run's note in the old language until
+the next run rewrites it — usually the next night. The alternative (store a code, render live) needs a
+dozen new persisted fields and a legacy path for each: the R-570 shape a dozen times over.
+`EndRestoreOp` now receives no Hungarian literal from anywhere.
+
+**[FACT] A deadlock, introduced and caught by the suite hanging (R-578).** `UpdateOffboxStatus` holds
+the settings WRITE lock while running its callback; `boxLang()` reads the language through the READ
+lock; `sync.RWMutex` is not reentrant. A note rendered inside that callback deadlocks **holding the
+settings lock**, which wedges everything else on the box that touches `settings.json`. The only
+symptom was `go test` going from 8 minutes to a 25-minute timeout. **The general rule this establishes:
+a helper that takes a lock must never be called from inside a callback that holds one** — and a hang
+is the worst symptom to diagnose, which is why R-578 asks for a gate rather than one test in one package.
+
+**[DESIGN] Decision 6, superseded a second time: the switch is a GLOBE, and a visitor's language is
+their own.** One answerable sentence: *how does someone who cannot read Hungarian find the way out of
+Hungarian?* Options: (1) keep two text links („Magyar"/„English") in the sidebar footer — cost: they
+wrap at the sidebar's width, and finding them means recognising two words as links; (2) one globe, the
+symbol every web user already reads as "language". **Chosen (2)**, `<details>`/`<summary>` so the menu
+needs no script and a screen reader announces it. Language names inside are shown in their own
+language and are never translated. Drawn inline rather than in the icon sprite, because the sprite
+lives only in `layout.html` and the pages outside the dashboard chrome have their own shell.
+
+**[DESIGN] Who the page is FOR decides where its globe posts, and getting that wrong makes the button
+do nothing.**
+
+| page | reader | globe posts to | their choice lives in |
+|---|---|---|---|
+| every dashboard page | the household, signed in | `/settings/language` (session CSRF) | `settings.json` |
+| `/recovery` — an AUTHENTICATED route | the household, signed in | `/settings/language` | `settings.json` |
+| `/login`, `/claim` | a visitor, no session | `/lang` (no CSRF) | the `felhom_lang` cookie, their browser |
+| the two guest share pages, the catch-all | a stranger / nobody | **no globe** | — (R-577, the operator's) |
+
+`langFor`'s order is fixed: `?lang=` → **the household's setting when a session exists** → the cookie
+when there is none → the setting → `hu`. **A signed-in household never reads the cookie**, so they
+cannot inherit a language a previous visitor picked in the same browser. The recovery row above was
+measured live before it was right: an anonymous form there sets a cookie that `langFor` then ignores,
+and the button appears to do nothing.
+
+**[FACT] Where the globe SITS, and a stale-stylesheet trap that only a screenshot could show
+(v0.255.0, R-579).** On the pages outside the dashboard chrome the globe is **inside the card, centred
+under the footer**, with the menu opening upward — the shared `.lang-globe-menu` rule, so the two
+surfaces cannot drift apart. It was first placed at the corner of the VIEWPORT, which read as a stray
+browser control rather than part of the page. And five of those shells requested `style.css` with **no
+`?v=`**, so a browser holding a copy from before the globe existed kept serving CSS with no
+`.lang-globe` rules and it rendered as a bare, unstyled `<details>`. **Every test passed, because they
+all read the markup and the fault was in which CSS file the browser fetched.** `Version` is now set in
+`executeTemplateLang`, once, for every shell.
+
+**[DESIGN] `POST /lang` is CSRF-exempt, for a reason narrow enough to check.** The only achievable
+effect of a forged request is to change the language of the page the victim's own browser shows them.
+It writes one display-only cookie, reads nothing, touches no setting, and `safeBackPath` refuses a
+protocol-relative `//host` as well as an absolute URL — *"starts with `/`"* alone is not the test,
+because a browser reads `//evil.example` as another origin. **If that handler ever gains a second
+effect it needs CSRF that day.** That is the anonymous surface `04-control-plane-authorization.md`
+governs: changing what a visitor reads is within it, changing anything the household owns is not.
+
+**[DESIGN] §16, the operator's default, taken: a successful CLAIM carries the visitor's language into
+the household's setting.** Someone who switched the claim page to English and then claimed the box
+chose English. Only on success, and only there — the one moment an anonymous visitor becomes the
+household.
+
+**[FACT] The parity exceptions, measured rather than asserted.** 106 fixtures, a real (LCS) diff
+against the fixtures as they stood at v0.253.0: **3 change shapes** (the footer; the recovery globe;
+the login/claim globe) and **5 byte-identical**, which are exactly the pages that must not change.
+`audits/i18n-slice2-2026-09-18/C/parity-exception-diff.txt`. **A second measurement error worth
+keeping: the first attempt compared LINE BY INDEX, and an insertion shifts every line below it — it
+reported 60 520 changed lines and measured nothing. A line-index compare is not a diff.**
+
+---
+
+### 10.4 Slice 3 — the hub's e-mails follow the household (hub v0.118.x, controller v0.256.x). SLICE 3 CLOSED.
+
+SHIPPED 2026-09-18. Full design: `05-hub-architecture.md` §15.
+
+**The hub half (v0.118.0, v0.118.1).** `hub/internal/i18n`, 79 keys, hu authoritative, hu fallback,
+missing-key ceiling 0. Every customer mail and the public bind page render from it.
+`customerMessages`/`severityLabels` are DERIVED from the bundle, so a sentence is written once and
+"a new event type enters `allowedEventTypes` and `customerMessages` together" now means a line in
+`hu.json` plus its English twin. **56 mail goldens per language, captured from v0.117.0 before any
+string moved; all 56 Hungarian ones pass unchanged.** Language order: **last reported →
+created-with → `hu`**; `reports.language` defaults to EMPTY (never told us ≠ chose Hungarian) and
+the newest report is found by the autoincrement `id`, because `received_at` has second granularity.
+The bind page's `expired` state always renders Hungarian — it is the state an unknown token lands
+in, and the language must not answer what the text refuses to.
+
+**The box half (v0.256.0, v0.256.1).** `message_customer` on `POST /api/v1/event`: the same sentence
+in the household's language, `omitempty`, beside the unchanged Hungarian `message`. **A Hungarian
+household sends no second copy at all**, so the fleet's payload is byte-for-byte what it is today and
+the hub's fallback path stays the one production exercises. 19 producers render both from ONE bundle
+key; the Go parity gate checks all 19 against the base-commit literals. `customer.language`
+bootstraps a new box (stored choice → config → `hu`) and is never persisted into `settings.json`.
+v0.256.1 added the one observable the feature was missing: the push log says `[hu-only]` or
+`[+household(en)]`.
+
+**Proven live, twice.** Part A: a real English e-mail read in the operator's inbox and the Hungarian
+one 74 seconds later, same button, same box. Part B: the same event pushed 57 seconds apart showing
+`[hu-only]` then `[+household(en)]`, with an identical Hungarian sentence both times.
+
+**What is still Hungarian for an English household:** six producers whose sentence arrives already
+finished from another package (R-585) — of which `offbox_enlarge_blocked` matters most, because it
+has no hub entry so its raw sentence IS the mail. Plus the R-570 sentence. The 15 operator-tier types
+are Hungarian by design.
+
+**Gaps filed:** R-581 (same-second report ties, and `GetCustomers()` still has the shape), R-582 (an
+English copy-guard ported word-for-word convicted 141 honest sentences), R-583 (the test mail was the
+one mail that did not follow the language — and the one an operator would use to check), R-584
+(credential-bearing probes left in a live guest's `/tmp`), R-585. **R-555 closed.**
+
+
+### 2026-09-17 (on the starter)
+
+1. **Scope: what the household sees — the controller, its e-mails, the guide, the app catalog.** Not
+   the hub's operator pages.
+2. **Who picks:** the operator per customer at creation (default Hungarian); the household switches on
+   the dashboard; the box reports it so the hub's e-mails follow.
+3. **Fallback:** a missing English line shows the Hungarian one and is counted; never a key or a blank.
+4. **The first-boot wizard:** out of scope, obsolete — a separate row to delete it (R-554).
+
+### Decided by CC in the spike — operator may reverse
+
+5. **Mechanism (b2)** — §2.1.
+6. ~~**Switch hidden while only three pages are English** — §3.~~ **Superseded 2026-09-17** by slice 1
+   release C (v0.250.0): every template converted, switch shown to every household (§3).
+   **Superseded again 2026-09-18** by slice 2 release C (v0.254.0): the switch is a GLOBE, it is on the
+   sign-in and claim pages too, and a visitor's choice lives in their own browser (§10.3).
+
+8. **A successful claim carries the visitor's language into the household's setting** (§16 default,
+   taken 2026-09-18). Only on success; every other anonymous request leaves `settings.json` alone.
+
+### 2026-09-17 (evening) — the two open questions, ruled
+
+1b. **The console banner and the download page ARE in scope** (operator: „yes"). Slice 4 (R-559) is
+    unblocked; it stays late in the plan and rides an ISO release train.
+7. **Interface nouns translate** (operator: „translate"). „Indítópult" → Launcher, „Vezérlőpult" →
+   Dashboard, „Biztonsági mentés" → Backup, as the spike built. App names and „Felhom" stay as they
+   are. Every slice follows this.
+
+### 10.5 Slice 4 — the console banner and the download page (ISO 1.29.0 source, R-559)
+
+SOURCE SHIPPED 2026-09-18. **The image is built but NOT published** — that is an operator step; see
+`documentation/audits/i18n-slice4-2026-09-18/README.md`.
+
+**The box's screen is BILINGUAL, and that is a decision rather than a stage.** At the moment the
+pairing code is shown, nobody has told the box who owns it — there is no language to follow. So the
+three console texts carry the Hungarian block byte-for-byte as before, then one blank line, then an
+English block, inside the same frame: `print_pairing_banner`, `print_bound_banner` and
+`install_felhom_issue` (with the `postinst`'s byte-coupled copy of the issue text). The GRUB entries
+gain an English half. **§16 default taken: bilingual for good** — it needs no hub change, no protocol
+field, and it has no way to show the wrong language.
+
+**The Hungarian is a golden, not a grep** (`scripts/iso/test/golden/*.hu.txt`, captured before any
+English existed). The harness also pins: no Hungarian letter in the English block (with the Hungarian
+block as the positive control), every line ≤ 80 columns, and **the whole paint ≤ 25 rows**. The
+pairing banner is **24 rows on a 25-row console** — one row of margin, which is why the height is
+pinned: two more lines and the Hungarian pairing code, at row 5, scrolls off the top.
+
+**The download page has an English twin** at `felhom.eu/en/download`, linked both ways with
+`hreflang`. The rest of the marketing site stays Hungarian (ruling 1b). A site gate refuses the two
+pages naming different installer files or checksums.
+
+**The release gate had to be amended.** G16 required every Felhom-authored string to be Hungarian and
+would have stopped this publication; ruling 1b supersedes that scope, so G16 was rewritten rather
+than waived — Hungarian FIRST, pinned by the golden.
+
+**Gaps filed:** R-586 (the ISO harness had been red for two days and is in no gate), R-587
+(root-password files in the publish source directory), R-588 (release records live in two places).

+# AUDIT — can this check be fooled by a label? The decoy sweep (2026-09-01, R-421)
+
+**Question asked of every gate:** *could I satisfy this with a convincing label instead of the real
+thing?* Answered by construction — a decoy is written, the gate is run, and the verdict recorded.
+**No row's last column was answered from reading.**
+
+## The survey
+
+**29 distinct scripts, 35 registrations** (`reuse-refs`, `instructions`, `observations` are one
+script each, registered in three runners). This matches the task's count of 29.
+
+| gate | runner(s) | meant to prove | actually matches | shape | decoy passed **before**? |
+|---|---|---|---|---|---|
+| emoji | ctrl | no emoji in UI copy | codepoints, in `listdir` scope | 1 | **YES** |
+| native-confirm | ctrl | no OS-modal dialogs | JS call regex, `listdir` scope | 1 | **YES** |
+| app-row-dedup | ctrl | one row markup | regex + `'…' not in src`, `listdir` | 1, 2 | **YES** (×2) |

+| volume-persistence | catalog | data survives | runs containers, diffs | 5 | **UNKNOWN** |
+
+**19 sound · 4 holes left open with rows · 6 unknown.** Ten holes were fixed in this session.
+
+## The one cause behind eight of them
+
+Eight gates decided their **scope** with `os.listdir`, one directory level. No template or manifest
+subdirectory exists today, so every one was green **and correct** — and would have stayed green the
+moment anyone added `templates/partials/`, which is an ordinary act. `mojibake` and `docker-v`
+already used `os.walk`, caught the identical planted file, and are the **control that proves the
+cause was the listing and not the decoy.**
+
+## Holes left open, with rows
+
+| row | gate | why not fixed here |
+|---|---|---|
+| **R-422** | reuse-refs | `PATH_RE` matches 7 extensions; a rotted `.md` citation is invisible. Widening it needs a false-positive pass over 4 repos. |
+| **R-423** | site | `PAGES` is a hardcoded list of 7. Fix is to glob `website/*.html`, which needs the per-page exemptions rethought. |
+| **R-424** | one-register | a defect parked under state `idea` escapes. Declared in the gate's own docstring as residual hole 1. |
+| **R-425** | offbox-rename | fixed 3-entry `FILES` list; a new offbox file is unscanned. |
+| **R-426** | — | owns the meta-gate's 20-name exemption list. |
+
+Each is asserted **as it behaves today** where a test could hold it, so the day it is fixed the
+assertion fails and is updated deliberately. A hole nothing asserts is a hole nobody remembers.
+
+## Decoys withdrawn as illegitimate — mine, and named
+
+§2.1 sets the standard: a decoy nobody would write proves nothing. These were withdrawn rather than
+counted, because counting them would have manufactured findings.
+
+1. **image-pins / `x-image: nginx:latest`** — `x-` fields are inert in Compose. The label had no fact
+   behind it *either way*. Replaced with a positive control (a real untagged `image:` line → convicted).
+2. **release-complete / a non-version heading on top of CHANGELOG.md** — `HEAD_RE.search` scans the
+   whole file, so the real release is still found and named `v0.130.0`. The gate is sound.
+3. **app-row-dedup / one commented-out partial call** — `dashboard.html` has **two**; replacing one
+   left the other live. The gate was right and my decoy was half-built.
+4. **one-register / a 3-column decoy row** — it convicted for a *structural* reason, not the one under
+   test. Rebuilt at the real 5-column shape, and the hole then reproduced.
+5. **template-id, secret-markup, retrieval-promise, hub-copy / wrong content** — my first planted
+   files carried nothing those gates hunt for, so "passed" meant nothing. Rebuilt with real triggers.

+
+**Interventions a customer could not have made: Phase 2 = 2, Phase 3 = 0.**
+**Ready for a volunteer: NO** — the dashboard link does not open through the tunnel (R-510), a box installed for an
+existing customer gets no bind mail (R-509), and every box's file manager opens with `admin` / `admin` (R-513).
+
+Brief: `drills/BIGNIGHT-2026-09-14.md`. Evidence: `evidence-bignight-2026-09-14/` — `journal.md` (every observable in
+order), `alarm-truth-table.md`, `screens/`, `box-logs-phase2..4/`, `phase3/`, `phase4/`, `phase5/F1..F12`, `phase6/`,
+`teardown-*.txt`. Architecture read first: `00-capability-map.md`, `07-backup-architecture.md` §6 (the tiers),
+`09-update-architecture.md` §3 (decisions 1–9).
+
+## Venue
+
+VM 333 on demo-hp: ISO **1.27.1** (sha `25637007…`, found in the build output, not rebuilt), q35/OVMF, 4 cores,
+**16 GB** (the HP has 30 GB; 9201+9202 used ≈ 5.3 GB), system disk 200 G + data disk 100 G added after the install,
+both qcow2 on `nvme-scratch` (`/mnt/hdd_1`, its root). Customer „Tester 1" (`tester-1`, `enkicsifelhom.hu`,
+`tester1@felhom.eu`). Baselines: controller `406755fa` v0.242.0 · agent `4586f0f7` v0.130.0 · felhom.eu `a4d68441`
+hub v0.113.0 · catalog `6d6eec30`. Harness substitutions as the earlier walks: U.S. keyboard (H2), auto-reboot
+unticked and ISO detached (H3), text-mode installer (H4).
+
+**Off-site, as found:** the record has the DR tier (PBS on ep0) ticked and **restic off-site off**; ticking it
+provisions a Hetzner Storage Box (money, fenced), so it was not ticked. The DR tier then could not provision on the new
+box (R-511). **This box had no off-site tier of any kind; nothing was written to ep0.**
+
+## Phase 2 — the first hour (mail real this time)
+
+| step | result |
+|---|---|
+| install (one disk) | ≤ 2 m 45 s copying; the one-disk screen offers no choice; hostname and e-mail typed per the guide |
+| first screen | Felhom Hungarian text only (no `:8006` line) ✓; pairing banner repeats 3× after bind (R-214 class) |
+| data disk | hot-added; **nothing on dashboard, launcher or mail mentions it**; found under Tárhely → „Új meghajtó inicializálása"; enrolled in 2 s. A household would not know to enrol it |
+| bind mail | **none in 10 min** for an existing customer → **R-509 (P1), I1**: operator pressed „Send self-bind link"; mail arrived in 1 s |
+| self-bind link | **works end to end** (first walk to exercise it): code + Tulajdonosi jelmondat → „Sikeres összekötés." |
+| setup-code mail | arrived 54 s after bind — the **reinstall** mail („újratelepült … A korábbi jelszavad már nem érvényes"), not the first-install mail the guide names; **the mailed code worked** |
+| version | controller 0.242.0 + agent 0.130.0, current, no self-update needed ✓ |
+| **gate: dashboard via tunnel** | **FAIL** — 502 ×9: route reaches the box but lacks „No TLS Verify" → **R-510 (P1), I2**; LAN address used from then on |
+
+## Phase 3 — twelve apps, seeded through their front doors
+
+All 12 deployed on the default box — **the memory guard never refused** (guest 11 828 MB; ≈ 3.5 GB used with 12 apps).
+Every app „Fut · Naprakész" (12/12). Seeds: BookStack 5 Hungarian pages + 2 attachments (sha equal) + 2nd user +
+delete/undo; Docmost space + 5 docs + rename/delete/restore; PrivateBin 5 encrypted pastes incl. 10-min expiry;

+scan 5 s → stream; Mealie 5 recipes + meal plan; Uptime Kuma 3 monitors (its first screen is English, R-516; the
+box's own names show DOWN through R-510); AdventureLog trip with visits (photos fail from a non-browser client — R-483

+that do not exist (**R-517, P1**). Hub: box ok, 24/24 containers, drive shown, true `whole_guest_backup_failed` mailed.

+
+- **Machine (VM 333):** destroyed with both disks at 22:25:58Z; ISO 1.27.1 and harness files removed from demo-hp; no
+  firewall table left. `pvesm status`: `nvme-scratch` back to 10 140 556 KiB (10 134 820 before the drill), `local`
+  23 071 188 KiB (23 041 736 before), `local-lvm` 44.17 % unchanged all night. Evidence `teardown-before.txt`,
+  `teardown-layer1-machine.txt`. `pct fstrim` not applied: only deleted qcow2 files on a dir storage were used.
+- **Host (hub record + ep0 peer):** host `tester-1-a61396` deleted at 22:59:21Z once stale (the first attempt was refused
+  for a missing `confirm_host_id` — harness); host page 404; after the 23:04:13Z peer sync ep0 lists **no peer
+  `10.77.0.5`** (read-only check). Evidence `teardown-layer3-hub.txt`.
+- **Hub customer:** **„Tester 1" is KEPT** (the volunteer's record). Its off-site data on ep0 — namespace `tester-1`,
+  one snapshot directory from the doorstep walk — is **kept, stated**, for the operator to rule (R-511 context).
+- **Untouched, and checked:** demo-hp 9201 and 9202 (running throughout; only read-only loopback probes, R-513);
+  `drill-r50` (does not exist, R-461); DooPlex (read-only plus git pushes); Peti's box (not contacted); ep0 (read only).

+# DIAG — the SMART `PASSED` trap, and the disk alert that reached nobody
+
+**Date:** 2026-08-14
+**Drive:** Seagate `ST3000VX010-2E3166`, S/N `Z6A07P2G`, 3.0 TB, `/dev/sdg` on **DooPlex**
+**Fixtures:** `fixtures/smart-ST3000VX010-failing-2026-08-14.json` (raw `smartctl -a -j /dev/sdg`),
+`fixtures/smartd-history-sdg-2026-08-14.txt` (406 `smartd` journal lines for this device, 11–14 Aug)
+**Status:** the three controller defects named here are FIXED in controller **v0.215.0**; the
+counterfactual in §5 is derived from source, **not** reproduced live.
+
+This is the project's first genuinely failing disk. Before it, the capability map recorded the
+disk-failure scenario as *"Healthy path only — a genuinely failing disk has never been seen."*
+
+---
+
+## 1. What happened
+
+On **11 August 12:28** a 3 TB drive in DooPlex reported its first unreadable sectors. By **13 August
+21:58** it was at 360, and it was taking down a running service. Throughout the entire episode the
+drive's own overall self-assessment read **`PASSED`**, and it still does.
+
+`smartd` was running the whole time and mailed **local root** — a mailbox nobody reads. The failure
+was actually found by a crashlooping pod, not by any alert.
+
+---
+
+## 2. The mechanism — `smart_status.passed` cannot fail on unreadable sectors
+
+Measured, from the committed fixture:
+
+| ID  | Attribute                | value | worst | thresh | raw    |
+|-----|--------------------------|-------|-------|--------|--------|
+| 5   | `Reallocated_Sector_Ct`  | 100   | 100   | **10** | 0      |
+| 187 | `Reported_Uncorrect`     | **1** | **1** | **0**  | **1001** |
+| 188 | `Command_Timeout`        | 100   | 100   | **0**  | 0      |
+| 197 | `Current_Pending_Sector` | 98    | 98    | **0**  | **352** |
+| 198 | `Offline_Uncorrectable`  | 98    | 98    | **0**  | **352** |
+| 199 | `UDMA_CRC_Error_Count`   | 200   | 200   | **0**  | 0      |
+
+`smart_status.passed` is false only when some attribute's **normalized value** falls **at or below**
+its **threshold**. Attributes 187, 197 and 198 — the three that record unreadable sectors — all carry
+`thresh: 0`. A normalized SMART value floors at 1 and cannot reach 0.
+
+> **Therefore `smart_status.passed` is structurally incapable of failing on unreadable sectors.**
+> This is not a quirk of this drive or this vendor. It is how a zero threshold behaves.
+
+Attribute **187 `Reported_Uncorrect` sits at normalized `1` against threshold `0`** with a raw count
+of **1001**. It is one point from failing and has no remaining point to give.
+
+Corroborating, from the same fixture: `ata_smart_error_log.summary.count = 1001`, power-on hours
+**60505** (~6.9 years), `smartctl` exit status **64** (bit 6 — *the device error log contains
+records of errors*) while `smart_status.passed` is still `true`.
+
+**Any monitor built on the drive's overall verdict is blind to this entire class of failure.**
+Felhom already knows better — `agentapi.DiskVerdictFor` reads the raw counters — which is why it
+would have noticed on 11 August, two days early.
+
+---
+
+## 3. Unreadable sectors are not monotonic
+
+From `smartd-history-sdg-2026-08-14.txt`, `Current_Pending_Sector` over the episode (30-minute
+sampling, host clock = CEST):
+
+```
+Aug 11 12:28   8      first sighting
+Aug 11 12:58  16      (+8)
+Aug 11 13:28   0      FULL CLEAR — "No more Currently unreadable (pending) sectors,
+                       warning condition reset after 1 email"
+Aug 11 20:28   8      returns
+Aug 12 01:28  16  →  01:58   8  (-8)
+Aug 12 02:28  32  →  02:58  24  (-8)
+Aug 12 03:28  24      187 Reported_Uncorrect 100→97; ATA error count 0→3
+Aug 12 03:58  16  (-8)  →  04:28  24  (+8)
+Aug 12 10:58  32      … steady 32 for ~11h …
+Aug 12 21:58  24  (-8)
+Aug 13 03:28  40  (+16)  →  04:28  24  (-16)
+Aug 13 11:28  64      terminal run begins — never returns below 64
+Aug 13 11:58  72   12:58  80   13:28 112   15:58 120
+Aug 13 21:58 360      (+240)
+Aug 13 22:28 352  (-8)   … steady 352 through 14 Aug …
+```
+
+Two measured facts carry design weight:
+
+1. **The 11 August excursion cleared completely within one hour** (12:28 → 13:28). A bare `> 0`
+   alarm would have fired on a drive that then looked fine for seven hours. This is why the ladder
+   uses a *sustain* rule rather than a bare non-zero test.
+2. **The benign excursion peaked at 16; the terminal run crossed 64 at 13 Aug 11:28 and never came
+   back.** That is the entire empirical basis for the static count threshold of 64 — see §6.
+
+---
+
+## 4. The three controller defects
+
+All three are in `felhom-controller` at `3e3ee94` (v0.214.0), the tree audited here.
+
+### D1 — the alert carries a severity the hub does not recognise *(highest value)*
+
+`internal/notify/notifier.go:565` — `NotifyDiskHealthDegraded` sets:
+
+```go
+severity := "warn"
+```
+
+The hub accepts an exact-match lowercase vocabulary and **coerces anything else to `info`**:
+
+- `felhom.eu/hub/internal/api/handler.go:2121-2126` — `case "info", "warning", "error", "critical":`
+  … `default: payload.Severity = "info"`
+- `felhom.eu/hub/internal/notify/dispatcher.go:89-96` — `severityNotifies` returns true only for
+  `warning` / `error` / `critical`.
+
+`"warn"` is not in the accepted set. So the Figyelmeztetés-level disk alert is **stored as an
+informational notice and emailed to nobody**, on the customer leg and the operator leg alike.
+
+The function's own doc comment reads *"The hub applies its own per-event-type cooldown"* — which
+presumes it routes. An invariant asserted in a comment with no test pinning it; this project's
+recurring shape.
+
+### D2 — no level above "worth keeping an eye on it"
+
+`internal/agentapi/diskverdict.go:28-41` returns `Warn` for *any* non-zero counter, and can only
+reach `Fail` when `Health == "FAILING"` — which, by §2, this fault class cannot produce. A drive with
+one aging sector and a drive at 352 unreadable sectors rendered the identical chip and the identical
+mild sentence.
+
+### D3 — it speaks once, and forgets on restart
+
+`internal/web/disk_health.go:182` emits only on `v > prev`, against a **in-memory** baseline
+(`disk_health.go:26-29`, *"Lost on restart → the next check re-baselines silently"*). Consequences:
+
+- Between 8 and 352 pending sectors the verdict never changes level, so **nothing further is emitted**.
+- A controller restart while a disk is already bad re-baselines it silently — that disk never alerts
+  again.
+
+---
+
+## 5. Counterfactual — what a customer would have received
+
+**Derived from the source above plus the §3 timeline. NOT reproduced live.**
+
+| Date/time | Drive state | Felhom verdict at v0.214.0 | Emitted | Delivered |
+|-----------|-------------|-----------------------------|---------|-----------|
+| 11 Aug 12:28 | pending 8 | OK → Figyelmeztetés | `disk_health_degraded`, severity `warn` | **nothing** — coerced to `info`, dropped by `severityNotifies` |
+| 11 Aug 13:28 | pending 0 | Figyelmeztetés → Rendben | none (recovery is silent) | nothing |
+| 11 Aug 20:28 → 13 Aug | 8 → 352 | Figyelmeztetés throughout | none (no level change) | nothing |
+| 13 Aug 21:58 | pending 360 | Figyelmeztetés | none | nothing |
+
+> **Felhom would have emitted zero emails about this drive.** The one event it did produce was filed
+> at `info` and delivered to no one.
+
+Note the two defects compound: even had D1 been fixed alone, the customer would have received a
+single mild "Javasolt figyelemmel kísérni" at 8 sectors on 11 August and then silence through 352.
+
+---
+
+## 6. Provenance of the thresholds chosen in v0.215.0
+
+- **64 unreadable sectors → Hiba.** The observed benign excursion peaked at **16** and cleared inside
+  an hour; the terminal run passed **64** at 13 Aug 11:28 and never returned below it. 64 sits above
+  the one observed transient and below the observed terminal run. **This is a judgement from ONE
+  drive.** It is a static backstop and is expected to be replaced in Phase 3 by growth-rate detection
+  over real history.
+- **Sustain before count.** The primary rule is "unreadable sectors still present at the next check";
+  the count is the backstop. On this drive sustain fires **12 Aug**, the count not until **13 Aug** —
+  a full day earlier. The backstop exists for a box that was powered off or restarted across the
+  sustain window.
+- **55 / 60 °C.** Adopted unchanged from the operator's existing Prometheus bands on DooPlex, so the
+  two systems cannot disagree about the same drive.
+
+---
+
+## 7. Measured vs inferred
+
+**Measured** (reproducible from the committed fixtures):
+- The attribute table, thresholds and raw values in §2; `passed: true` at 352 pending sectors.
+- The full non-monotonic timeline in §3, including the one-hour full clear.
+- The three defect locators in §4 — read from live source on both the controller and the hub side.
+
+**Inferred** (source-derived, not executed):
+- The §5 counterfactual. It follows from the §4 locators and the §3 timeline; **no email path was
+  exercised against this drive**, and no `disk_health_degraded` event for it exists in the hub.
+
+**Not covered here:**
+- Attributes **187**, **199** and **188** are not on the agent→controller wire today. Adding them is
+  Phase 2 (a declared wire change, so the hub models them in the same session under G-1). Everything
+  the v0.215.0 fix needs was already on the wire.
+- The new Fail-from-counters path has **not** fired on real hardware — only against this fixture's
+  values in unit tests.
+
+---
+
+## 8. One layer out
+
+`smartd` on DooPlex did its job and mailed local root, where nothing reads. That is the same shape
+as D1 — a correct detection with a delivery path to nowhere — one layer outside the product. Tracked
+separately as DooPlex hygiene.

+# DOORSTEP — the first hour again, on the unpublished installer (2026-09-14)
+
+**Interventions a volunteer could not have made: 1** — I1 again, now with a different cause (R-505).
+**Ready for a volunteer: NO — because on customer `tester-1` the dashboard link answers 503 from our
+network: the box's tunnel connects but receives no routes. Everything the task changed held.**
+
+Evidence: `evidence-doorstep-walk-1270-2026-09-14/` — `screens-331/`, `screens-332/`, `box-logs-331/`,
+`A1-power-cut-331.txt`, `A2-typo-331.txt`, `step10-remove-observe-331.txt`, `G15-live-332-iso1271.txt`,
+`teardown-*.txt`. Gate records: `../tests/iso-release-1.27.0-2026-09-14/`,
+`../tests/iso-release-1.27.1-2026-09-14/`. Yesterday's walk for comparison:
+`DRILL-fresh-install-0242-2026-09-14.md` and its `screens/`.
+
+---
+
+## 0. Phase 0 — why the installer asked questions (named first, because the brief assumed otherwise)
+
+**The auto-install never engaged, by construction.** The public 1.26.1 manifest (downloaded from
+`iso.felhom.eu`) reads `answer-file : NONE — no answer.toml, no auto-installer-mode.toml (release gate
+G1)` and `automated-entry : NOT PRESENT`; `build-felhom-iso.sh --release` refuses a profile and skips
+`prepare-iso`; `grub/grub-release.cfg.tmpl` explains why — SPIKE-universal-iso-1 measured that no udev
+property separates an internal disk from a USB backup drive and that a two-disk filter silently wipes
+one. The operator's 2026-07-31 ruling made the interactive installer the product. **Offered an
+install-time disk rule on 2026-09-14, the operator kept that ruling.** The auto-installer has no local
+chooser or stop page (its modes are a static answer from the image or a partition, or an HTTP answer
+service), so "no English reaches a volunteer" cannot hold on the installer's own screens; the
+Felhom-written text around them is Hungarian (G16) and the guide answers each screen.
+
+## 1. What was built
+
+| artifact | change | status |
+|---|---|---|
+| ISO **1.27.0** | `felhom-bootstrap.sh` masks `pvebanner` + writes Felhom `/etc/issue` at first boot; banner names the Tulajdonosi jelmondat | built, gated, **superseded** — its proof install still showed the Proxmox block on the first boot |
+| ISO **1.27.1** | the postinst does the mask (symlink) and the issue write at install time; issue text without ő/ű | built, **gated PASS**, proven live on VM 332, **NOT PUBLISHED** |
+| hub **v0.113.0** | hand-over sentence on customer create + Credentials; self-bind mail names the operator | **deployed**, rendered live on `tester-1`'s page |
+
+## 2. The disk rule, and what a volunteer sees in each case
+
+**The installer never picks a disk for you.** It lists every disk with size and model; you choose the
+one the system goes on, and that disk is erased. Unplug the external backup drive during the install.
+If you do not know which internal disk is right, stop and call the operator.
+
+| case | what the screen shows (measured) |
+|---|---|
+| **one disk** (VM 332, TUI and graphical) | TUI: `Target harddisk: /dev/sda (QEMU HARDDISK) (64.00 GiB)`; graphical: „Please verify the installation target … All existing partitions and data will be lost." with `Target Harddisk /dev/sda (64.00GiB, QEMU HARDDISK)` |
+| **three disks** (VM 331, TUI) | the same field pre-set to `/dev/sda (200.00 GiB)`; opening it lists `/dev/sda (200.00 GiB)`, `/dev/sdb (50.00 GiB)`, `/dev/sdc (50.00 GiB)` (screen `331-s07`); **the installer does not ask "which one?" by itself** — the guide's disk row covers it |
+| **nobody at the keyboard** (VM 332) | the 15 s menu boots the **graphical** installer, which stops at the EULA and waits (screen `332-s02`) — nothing installs unattended |
+| zero disks | not exercised |
+
+## 3. The walk, step by step
+
+Customer **`tester-1`** (operator's choice), domain `enkicsifelhom.hu`, tunnel token set, DR tier on,
+**no e-mail registered**. VM 331 = ISO 1.27.0, three disks, TUI. VM 332 = ISO 1.27.1, one disk.
+
+| # | step | result | time |
+|---|---|---|---|
+| 1 | installer | built from `main`, not downloaded (unpublished) | — |

+| 3b | first screen (332, **1.27.1**) | **Felhom text only** — „Felhom otthoni szerver · Ezen a gépen most nincs dolgod, és bejelentkezni sem kell." — then the pairing banner naming the Tulajdonosi jelmondat; identical after a **proven** reboot (boot 16:14:11Z > reboot 16:13:56Z, `pvebanner` masked, `/etc/issue` 0 × `8006`) | — |
+| 3c | bind + claim (331) | operator bind (no link: no e-mail); hub `claim code generated … but customer tester-1 has NO registered email` (R-508); **dashboard 503 via the tunnel → I1 (R-505, filed 16:07:59Z before acting)**; claim by LAN + box-printed code (H1) → 302 | controller 0.242.0 at +2 m 31 s after bind |

+
+## 4. Harness substitutions (not interventions)
+
+H1 no mailbox (and `tester-1` has none) → operator bind, box-printed codes · H2 U.S. keyboard on 331/332-TUI
+· H3 auto-reboot unticked, ISO detached · H4 TUI entry. **H5 (new): the graphical installer did not take
+Tab or mouse input from `qm sendkey`/`mouse_move`; Alt+N worked** — the 1.27.1 graphical path was proven
+to boot, wait at the EULA, show the one-disk target and reach the password screen, not to install
+(R-507).
+
+## 5. Findings
+
+| row | rank | |
+|---|---|---|
+| **R-505** | **P1** | `tester-1`'s tunnel gives a fresh box no routes → 503 (12/12 probes, 12 box warnings, 0 config updates); operator's phone reaches it — cause not visible to the session |
+| R-508 | P2 | `tester-1` has no registered e-mail: the setup code and self-bind link cannot be delivered |
+| R-506 | P3 | `day0-install.md` A.1 says the controller manages hostnames — it does not |
+| R-507 | P3 | the proof-install harness cannot drive the graphical installer |
+| R-502 | P3 | the bootstrap harness runs in no gate/CI; the banner was never tested |
+| R-503 | P3 | spike for an install-time disk rule (not chosen) |
+| R-504 | P3 | `iso.felhom.eu/` has no index; download page goes on the website |

+## 6. Teardown
+
+Layers 1–2 measured in `teardown-layers-1-2.txt` (VMs 331/332 destroyed; `nvme-scratch` used 23 528 192
+→ 10 132 924 KiB; `local` 26 489 992 → 23 033 320 KiB; ISOs and `/root/doorstep` gone; 9201/9202 running;
+`local-lvm` 44.17 % unchanged). Layer 3 in `teardown-layer3-hub.txt`: appliance 27 discarded; host
+`tester-1-8603a2` deleted at 16:46:52Z once stale; its ep0 peer gone at the 16:49:13Z push (**customer
+`tester-1` is KEPT** — the operator's fixture; a RESET or DELETE would remove its tunnel and zone). **Left on
+ep0 by the DR tier, measured read-only:** namespace `tester-1` with **2 directories of backup data** and
+token `felhom@pbs!tester-1`; a host delete does not deprovision tenancy — only the customer RESET does,
+which would also remove the tunnel. Disposition: retained with the customer, for the operator to rule.

+paperless-ngx: the database is dumped into a directory for a stack that does not exist,
+so the recovery unit never contains it, and the restore then tells the customer the app
+has no database. Proven live 2026-08-21 22:39-22:45 CEST on demo-hp.
+
+MECHANISM (source):
+  internal/appbackup/dbdump.go:770 deriveStackName("paperless-postgres", known)
+    1. candidate = suffixStripStackName("paperless-postgres") = "paperless"   (line 801)
+    2. known is non-empty, known["paperless"] is FALSE   (the stack is "paperless-ngx")
+    3. known["paperless-postgres"] is FALSE
+    4. no known stack name is a prefix of "paperless-postgres"  ("paperless-ngx" is not)
+    5. FALLS THROUGH to `return candidate`  (line 797) -> "paperless"
+  An unresolved mapping is returned as if resolved. There is no warning and no refusal.
+
+OBSERVED CONSEQUENCES (all live):
+  a) the dump is written to
+       /mnt/sys_drive/felhom-data/backups/primary/paperless/db-dumps/paperless-postgres.sql
+     284,617 bytes, 72 tables, valid=true  -- an orphan directory for a non-existent stack,
+     on the SYSTEM drive, while the app's real unit is on /mnt/felhom-drives/hdd_1.
+  b) the real unit /mnt/felhom-drives/hdd_1/backups/primary/paperless-ngx/manifest.json
+     records  "db_dumps": null
+  c) the off-site snapshot therefore carries no .sql at all
+     (checking folder: `find ... -name "*.sql" | wc -l` = 0)
+  d) writeSafetyDump (offbox_reconstitute.go:115) filters discovered DBs on
+     db.StackName == stackName, so `mine` is empty -> returns ("", nil) -> hasDB = false.
+     NO pre-restore safety dump is taken.  Verified: `find /mnt -name "pre-restore-*"`
+     returned nothing before AND after the destructive restore.
+  e) the destructive restore ran to completion and reported SUCCESS:
+       "A(z) paperless-ngx: 0 fájl visszaállítva (mentés: 2026-08-21 22:41)
+        — az alkalmazás újraindult. Ennek az alkalmazásnak nincs adatbázisa."
+     The controller had dumped that same database 5 minutes earlier.
+
+The orphan directory is also invisible to the app's off-site push, because the push
+resolves paths from the app's own unit path -- so the only copy of that database dump
+is on the system drive of the machine it protects.

+PART 4 — things we claim and have never watched. demo-hp, 2026-08-21, times CEST.
+
+4.1 THE DESTRUCTIVE RESTORE
+  (a) "nothing is ever deleted"  -- PASS, both directions, calibre-web 22:26:59.
+      POST-SNAPSHOT.txt, created after the snapshot, SURVIVED the restore.
+      plain.txt, mutated after the snapshot, was OVERWRITTEN back to the snapshot's
+      content (sha 07e91a98…). Copier is rsync -a, no --delete, no --ignore-existing
+      (offbox_reconstitute.go:94).
+      NOTE ON THE COUNT: the message says "2 fájl visszaállítva" because rsync counts
+      TRANSFERS, not files restored. An identical restore reports "0 fájl visszaállítva",
+      which is indistinguishable from a restore that did nothing.
+
+  (b) "a safety dump is taken and VERIFIED before anything is stopped, and the whole
+      operation refuses if it cannot be"
+      HAPPY PATH -- PASS, romm 23:02:44.
+        21:02:47Z  "[offbox] romm: pre-restore safety dump written →
+                    pre-restore-20260821T210246Z-romm-mariadb.sql (60.8 KB)"
+        21:02:47Z  "[stacks] StopStack romm: current state=running"
+        The dump precedes the stop. Message correctly said
+        "0 fájl és az adatbázis visszaállítva".
+      THE REFUSAL -- PASS, romm 23:04:15.
+        Safety dump made impossible by putting a regular FILE at the db-dumps path.
+        Result: ok=FALSE,
+          "A teljes visszaállítás sikertelen: a biztonsági mentés könyvtára nem hozható
+           létre: mkdir /mnt/felhom-drives/hdd_1/backups/primary/romm/db-dumps:
+           not a directory"
+        Nothing changed: plain.txt kept my post-snapshot mutation (sha 3754dfc6…), and
+        romm's container StartedAt was unchanged (21:03:08) -- the app was never stopped.
+        JUDGEMENT: honest and it names the path, but it leaks a raw Go mkdir error into
+        a customer surface.
+      THE HOLE -- the guard only protects apps whose database the discovery resolves to
+        the right stack. For paperless-ngx it concludes "no database", so hasDB is false
+        and the refusal CANNOT fire: the undo is absent rather than refused. See
+        ../phase4-paperless/FINDING.txt.
+      SIDE EFFECT, NOT PREVIOUSLY FILED -- the safety dump DESTROYS the unit's own DB dump.
+        DumpOne writes the canonical `<stack>-<dbtype>.sql` (appbackup/dbdump.go:200-202),
+        i.e. the app's real dump, and only THEN is it renamed to pre-restore-*.
+        The comment at offbox_reconstitute.go:147-148 states it "can never overwrite the
+        app's real dump". It does.
+        PROVEN: romm's db-dumps held romm-mariadb.sql (62,270 B) at 22:59; after one
+        reconstitute it held ONLY pre-restore-20260821T210246Z-romm-mariadb.sql.
+        Consequence: until the next backup run the LOCAL restore-from-unit finds no .sql
+        and tells the customer the app has no database.
+
+4.3 A DAMAGED STORE  -- MIXED
+  Method: one byte flipped inside pack 967853d2… (offset 5,000,000) via the repo's own
+  SFTP transport; the pack's name is its content hash, so this is genuine corruption.
+  * `restic check` DOES detect it ("ciphertext verification failed",
+    "Fatal: repository contains errors").  BUT the controller NEVER RUNS `restic check`:
+    the only restic verbs in the whole controller are restore, snapshots, backup, unlock,
+    stats, init, forget, prune, cat. The agent's restore-test is PBS-tier only.
+    So the off-site store is never verified by any layer, at any time.
+  * A restore that TOUCHES the damage fails honestly:
+    ok=FALSE, "A visszaállítás sikertelen: offbox restore paperless-ngx: exit status 1:
+    … ignoring error for …/documents/originals/0000011.pdf: ciphertext verification failed"
+  * BUT the failure is not remembered. It left a PARTIAL scratch (78 MB, 54 files,
+    15 of 16 originals). OffboxFullScratchReady (offbox_restore.go:305) only asks
+    "does the directory exist and is it non-empty", so the wizard then offered all three
+    actions including "Teljes visszaállítás indítása".
+  * Pressing it ran the DESTRUCTIVE restore from that known-incomplete copy and reported
+    SUCCESS: ok=TRUE, "A(z) paperless-ngx: 0 fájl visszaállítva … Ennek az alkalmazásnak
+    nincs adatbázisa."
+  REPO REPAIRED afterwards from the byte-identical originals; `restic check` now says
+  "no errors were found".

+# DRILL — CHAOS NIGHT: random actions on random apps while random things go wrong (2026-09-16/17)
+
+**Interventions: 1.** One, at 21:59:45Z in round 6: I killed the **local leg** of a whole-guest
+backup that could never have fit (a ~29 GB source into a 14 GB root filesystem, falling at ~16 MB/s).
+The **off-site leg then ran by itself from the same snapshot and succeeded**, so the data still left
+the house. Both pre-declared presses went **unused**: the automatic self-bind mail was already
+waiting, and the acknowledged-delete path re-issued the PBS credentials on its own. Phase 0's
+seeding repairs are listed separately in `evidence-chaos-night-2026-09-17/interventions.txt` — that
+damage was mine, not the product's, and every repair went through the product's own endpoints.
+
+**Ready for a volunteer: still yes.** Across twelve rounds — a power cut mid-restore, a hard reset
+four seconds into another, a full disk, a killed tunnel, a restarted Docker, three severed networks
+and the data drive pulled out of a running machine for twenty minutes — **nothing cost a byte of
+customer data, and the box healed itself every single time with no human involved.** Seventeen
+alarms fired, **all seventeen were true, none were missing**, and the mailbox proves every one was
+**delivered** rather than merely stored. The honest qualifications: two P2 legibility gaps are filed
+(an interrupted restore leaves no record; one failed report spends the whole 30-minute staleness
+budget, measured at 29 m 59 s), and one thing this night could **not** test — per-app off-site
+restore, because this box is a rebuild whose restic repository is orphaned **by design**, which the
+product surfaced honestly within seconds.
+
+**The accident-plus-action pair that hurt most: `restore` + hard reset (round 10).** Not because the
+box suffered — it was back with 26 of 26 containers in **150 s**, boot reconciliation naming the app
+it recovered, every front door serving. It hurt most because it is the **only** pair of the night
+where the household is left not knowing what happened: they pressed restore, were told it had
+started, the machine went dark four seconds later, and afterwards **nothing anywhere tells them
+whether it finished.** The status surface exists and answers with the zero value; the record is
+in-memory only and does not survive the machine stopping.

+## The schedule — drawn ONCE, before round 1, and written here first
+
+The point of this section's position in the document is that the night could not be chosen after the
+fact. `chaos_schedule.py` is committed beside the evidence; re-running it reproduces this table.
+
+- **seed:** `20260917` (the date)
+- **script sha256:** `4b98afe65d042df7e7dc417553b33565cfbb4afd451c68456a7cabec0858d2a1`
+- **generator:** `evidence-chaos-night-2026-09-17/chaos_schedule.py`, stdlib `random` seeded with the seed
+
+| # | time | X — the action | Y — the app | Z — the accident |
+|---|---|---|---|---|
+| 1 | 23:30 | offsite-run | adventurelog | nothing |
+| 2 | 23:55 | restore | gokapi | power cut |
+| 3 | 00:20 | use | bookstack | disk 95% full |
+| 4 | 00:45 | offsite-run | mealie | tunnel down 10min |
+| 5 | 01:10 | use | privatebin | docker restarted |
+| 6 | 01:35 | backup-system | adventurelog | nothing |
+| 7 | 02:00 | update | nextcloud | internet gone 10min |
+| 8 | 02:25 | backup-app | nextcloud | internet gone 10min |
+| 9 | 02:50 | use | uptime-kuma | internet gone 10min |
+| 10 | 03:15 | restore | uptime-kuma | hard reset |
+| 11 | 03:40 | use | paperless-ngx | drive pulled 20min |
+| 12 | 04:05 | use | paperless-ngx | nothing |
+
+**Re-draw log** — a silent re-draw is a schedule chosen by the person running it, so every one is here:
+
+- r02  X=reinstall re-drawn (nothing has been removed yet)
+- r06  Z=disk 95% full re-drawn (constraint 4: at most once)
+- r07  Z=nothing re-drawn (constraint 6: never two in a row after r2)
+- r08  X=reinstall re-drawn (nothing has been removed yet)
+
+**What the draw happened to give, said plainly before the night judges it:** no `remove` round was
+ever drawn, so `reinstall` had nothing to reinstall and was re-drawn twice (rounds 2 and 8). Three
+`internet gone` rounds land consecutively (7, 8, 9) — that is the seed's doing, and it makes rounds
+7–9 a de-facto endurance test of the same accident against three different actions rather than three
+independent samples. `controller killed`, `drive pulled 90s`, `memory pressure`, `agent restarted`
+and `hub unreachable` were never drawn at all; **this night does not test them**, and the morning
+verdict must not claim it did.
+
+## Phase 0 — the golden, the box, the household
+
+**0.1 Golden 0.245.0, baked and published.** Launched 19:52:47Z as a transient unit in the drill VM,
+finished 19:58:15Z. Markers: `overlay2`=1, `including mount point`=2, `upload OK (HTTP 201)`=1,
+FATAL=0, publish-skipped=0. `GOLDEN_SHA256=7a08aa1ad0bdd622247e1901e422ed2f72df22ef531a144135a44b66fc455626`.
+**The teardown was gated on the REGISTRY answering 200**, not on an exit code — and that mattered:
+the wrapper exited **144** while every measured outcome was good. Vouched in the hub and read back
+from the page (`golden currently vouched: 0.245.0`). The three bake failures of 2026-09-16 (`scp -P`,
+`chmod 0700`, `GITEA_USER=admin`) were each guarded and none recurred.
+
+*Decision, recorded because silence reads as agreement:* the global controller floor was left at
+0.244.0. The new box installs golden 0.245.0, which already carries controller 0.245.0, so no floor
+was needed to deliver anything tonight; raising it would have pushed an update onto demo-felhom, a
+box not in this drill.
+
+**0.2 The box.** VM 336 on demo-hp: 8 GiB, 4 cores, 32 G system + 100 G data disk on the NVMe at its
+root, booted from the **published** ISO 1.28.0. Boot order set in its own `qm set` (combining it
+silently yields `order=net0;ide2`). Install completion was judged **from the disk** — blocks used
+grew 3233 → 6942 MiB then held across three checks — because „Automatically reboot" is ticked and a
+finished install looks exactly like a stuck one on screen. The summary page was read before pressing
+Install, and the line that made it safe was **„Disk(s): /dev/sda"** — the 32 G system disk alone.
+
+**The walk, as a volunteer, cost ZERO operator presses.** The box registered itself as an unclaimed
+appliance and polled, visibly, until bound. The bind link came from the **waiting mail** (minted
+18:17:46Z by yesterday's acknowledged host delete), the pairing code off the box's own console
+(`4SY-4TX`), the „Tulajdonosi jelmondat" from the hub's customer record:
+  POST /bind/<token> -> 200, „Sikeres összekötés."
+Then day-0 ran on its own and the hub recorded, without anyone pressing anything:
+  `appliance_bound` (customer_selfbind) · `appliance_credential_delivered` · `claim_reissued_reenroll`
+  · `offsite_reissued` · **`pbsdr_auto_reissue` — „Previous key destroyed (acknowledged deletion) —
+  credentials re-issued automatically."**
+
+**That last event is a first.** The brief named „the WG hook provisions by itself after an
+acknowledged delete" as a claim never measured live. It ran tonight, unprompted. **Both pre-declared
+presses (O1 self-bind, O2 re-issue) were therefore unnecessary.**
+
+The dashboard was claimed with the mailed code and **proven by logging in with the new password** —
+a claim page that re-renders looks identical to success from the status code alone. The 100 GB data
+drive was initialised through the wizard's own endpoint (`POST /api/storage/init`, polled to
+`phase: done`), and `df` shows it mounted at `/mnt/felhom-drives/hdd_1` with 93 G free.
+
+**The box landed on tonight's golden with no hand upgrade:** controller **0.245.0** (healthy), agent
+**0.131.0**, host `tester-1-022354` ONLINE. And the **R-543 escrow reminder bar shipped hours earlier
+was live on it**, on a box nobody had touched.
+
+**0.3 The household — and the first real trouble.** Twelve deploys were fired; **ten were accepted,
+two refused** for memory with both numbers quoted. Then nine of the ten failed: the guest's disks are
+thin-provisioned over an ~11.8 GB pool carved from a 32 GB system disk, ten simultaneous image pulls
+filled it, and the hub recorded `storage_fill_critical` (100 %) plus **nine `app_deploy_failed`
+warnings**, one per app, each naming the failing pull. Only PrivateBin installed.
+
+**The product behaved; the harness did not.** R-536's failure event — shipped that same morning so an
+interrupted install is not silence — fired for all nine within two minutes. The memory guard refused
+rather than over-committing. The per-stack record stayed honest (`deployed: false`). The two faults
+were mine: firing twelve deploys in two seconds is not household behaviour, and a 32 GB system disk
+was copied from an earlier drill without checking what that drill had installed.
+
+**0.4 The escrow ceremony could NOT be completed — and this one is about tonight's own release.**
+See „Finding: the recovery-code step cannot be done when the guide says to do it" below.
+
+
+## Finding: the recovery-code step cannot be done when the guide says to do it (R-546)
+
+The box was at exactly the point of the guide this release added hours earlier — installed, bound
+with no press, claimed, drive initialised, **no apps yet** — and the escrow reminder bar was on every
+page telling the household to create their recovery code. It could not be done.
+
+    POST /api/escrow/start   -> 200   {"job_id":"escrow-1789590499667361664","phase":"running"}
+    GET  /api/escrow/status  -> claimable:false —
+         detail: "exit 2: … selftest=escrow-create requires -storage <pbs-storage-id> (or escrow.pbs_storage…"
+    POST /api/escrow/claim   -> **409** „A folyamat jelenlegi állapotában a kód nem kérhető le."
+
+**Both sides agreed on the cause.** The hub's own Backup & DR panel read „host enrolled **done** · WG
+tunnel peer registered **done** · descriptor provisioned (namespace tester-1, token felhom@pbs!tester-1)
+**waiting** · ceremony possible once the descriptor is applied on the box". The box had no PBS storage
+(`pvesm status`: `local`, `local-lvm` only) and no `escrow` section in `agent.json` at all.
+
+**It self-heals, and that was measured rather than assumed.** The box was left alone and polled:
+
+    20:30:12Z … 20:34:15Z   pbs_storage=none         escrow.pbs_storage_id=none
+    **20:35:16Z              pbs_storage=felhom-pbs   escrow.pbs_storage_id=felhom-pbs**
+
+~17 minutes after the bind. The retried ceremony passed every preflight item, the claim returned
+**200** (83-character code, 129.2 bits of entropy, revealed once), and `escrow_state` became
+**escrowed**. The bar then vanished from all four pages checked — the R-543 fix working through its
+whole lifecycle on a box nobody had set up for the test.
+
+**So the defect is timing and wording, not mechanism.** For ~17 minutes a volunteer following
+tonight's guide meets a stderr fragment about a `-storage` flag, while every page urges them on.
+Filed **R-546** (P2). No product code was changed — this is a validation run.
+
+## Phase 1 — the rounds
+
+Rounds run at ~25-minute spacing. The schedule above is fixed; only the wall-clock start moved,
+because Phase 0 ran long (the storage wizard submits by JavaScript and the endpoint was worked out
+rather than guessed). Round 1 began 23:07 CEST.
+
+### Round 1 — `offsite-run` / adventurelog / accident: **nothing** (control round)
+
+| the five things | |
+|---|---|
+| what the customer saw | „A távoli mentés elindult — az állapot itt frissül." and, at the end, „A távoli mentési tároló elárvult: a benne lévő mentések egy korábbi, már nem elérhető kulccsal készültek (újratelepítés)." |
+| what the box did by itself | walked all twelve apps — stop, dump each volume with real byte counts, restart — captured eleven, could not capture the one that was crash-looping, and finished |
+| time to steady | **1m45s** (`last_duration`), `last_run` 21:09:00Z, `progress.active` false, `last_error` empty. A control round: the box never left steady |
+| alarm fired / true? | **three, all true** — `app_start_failed` named Nextcloud · `backup_run_failures` „1 of 12 apps failed to back up in this nightly run: nextcloud" · `offbox_repo_orphaned`, matching the status endpoint's own `"orphaned": true` |
+| should have fired, did not | **none** |
+
+**Household loop in the window:** 3 lines marked FAILED, **all three mine** — the loop counted the
+dashboard's 301 redirect as a failure while accepting the same 301 for app reads. Fixed at 21:11:25Z
+and marked in the log; only lines after that marker are scored.
+
+**What round 1 actually establishes.** The off-site tier is armed (escrowed) and the run works
+end-to-end, but on THIS box — a rebuild for an existing customer — the remote repository was written
+under a key the box no longer holds, so **no snapshot was written**. That is the documented rebuild
+behaviour, surfaced honestly with the route out named in the message rather than reported as success.
+
+**Two things that looked like defects in this round and are not**, both established with controls
+rather than inference — five front doors answering 404 (traefik has no route to an unhealthy
+container; identical byte-for-byte to a no-such-host control) and a crash-looping Nextcloud (image
+layers corrupted while my thin pool stood at 100 %; „invalid ELF header", repaired by a re-pull).
+Detail in `evidence-chaos-night-2026-09-17/round-1-notes.txt`.
+
+
+### Phase 0 postscript — repairing my own damage, and three conclusions I had to retract
+
+Nine of the first ten deploys failed because I fired twelve at once onto a thin pool carved from a
+32 GB disk, and the pool hit 100 %. Repairing that took the rest of Phase 0 and produced **two
+distinct faults of mine, with different cures**, which only separating them made fixable:
+
+| fault | symptom | cure |
+|---|---|---|
+| image layers written while the pool was full | `php: … libxml2.so.2: **invalid ELF header**`, exit 127 crash loop | drop the image, let compose pull it again |
+| my re-seed generated **fresh database passwords** over volumes already initialised with the first set | Postgres `auth_failed`, MariaDB „Access denied for user … (using password: YES)" | remove the app **with its data**, deploy once with one consistent secret set |
+
+A fresh image did not fix gokapi and a fresh database did — that is the evidence the two faults are
+different things rather than one.
+
+**Three conclusions I wrote and then had to retract, each corrected where it stood:**
+1. „the five 404s were my mistimed sweep" — wrong for four of them. A **negative control** (a
+   no-such-host request) returned the identical 404 of 19 bytes, and a positive control returned
+   200/1200 bytes: traefik simply has **no route to an unhealthy container**.
+2. „nextcloud is repaired" — wrong. The re-pull fixed the crash, and the app still could not reach its
+   database. The container reported **`healthy`** throughout, because the image's own healthcheck asks
+   whether Apache answers, not whether the application works.
+3. „all the broken apps are corrupt layers" — wrong. bookstack logged a clean startup, gokapi logged
+   nothing at all, immich showed a Postgres auth failure.
+
+I also nearly filed a defect against the drive gate, which was working and logging at DEBUG while I
+read a settings snapshot inside its 30-second tick. **An absent log line is not evidence.**
+
+None of this is a product defect and none of it is filed as one. What the product did throughout was
+correct and legible: it refused to route to unhealthy containers, `app_start_failed` named the app
+that was down, `backup_run_failures` said „1 of 12 … nextcloud", the memory guard refused the
+eleventh and twelfth installs with both numbers quoted, and `storage_fill_critical` fired at 100 %.
+
+### Round 2 — `restore` gokapi / accident: **power cut**, 20 s into the restore
+
+| the five things | |
+|---|---|
+| what the customer saw | „Visszaállítás elindult — az állapot itt frissül." then the box went dark mid-restore; on return the dashboard and every app were back |
+| what the box did by itself | everything — containers 0 → **25 at t+131s** → **26 at t+148s**, nothing stuck, no shell used. **gokapi, the app being restored when the plug came out, returned `Up 30 seconds (healthy)`** |
+| time to steady | **148 s**, measured against the container count this round took itself before the accident |
+| alarm fired / true? | `controller_started` (info) — true and correct. **No false alarm.** |
+| should have fired, did not | **none** — per the ladder a 60-second outage yields no `node_stale` (30 min threshold) and no `app_start_failed` (90 s boot grace), and neither appeared |
+
+**Household loop: NOT COLLECTED.** The loop was a transient unit on the VM and died with the power
+cut — the first accident that could have produced household failures instead produced no lines at
+all. Zero lines is not zero failures, so it is recorded as not collected, and the loop is now a
+persistent systemd unit that returns with the box.
+
+**A finding this round handed over:** `app_oom` (warning) — „Alkalmazás memóriája elfogyott: immich
+(immich-postgres) — egy folyamatát a memóriakorlát leállította". That is immich's whole mystery
+solved: its Postgres was OOM-killed during the reverse-geocoding import, which is why the server saw
+`CONNECTION_CLOSED` and crash-looped twelve times. **The controller caught an OOM inside an LXC guest
+and named the exact container** — worth recording against this project's standing finding that those
+signals are usually invisible there. The diagnosis I spent twenty minutes reaching from logs was in
+the alarm feed, correctly labelled, the whole time.
+
+### Round 3 — `use` bookstack / accident: **system disk filled to 96 % for ten minutes**
+
+| the five things | |
+|---|---|
+| what the customer saw | **nothing.** wiki, status and paste all answered before, during and after. No banner, no warning, no mail — the household was never told the disk was full |
+| what the box did by itself | kept all twelve apps running on a 96 %-full root filesystem and released the space cleanly when the fill was removed (29 G used → 944 M used). The shared thin pool never moved (**39.69 %**) and the filesystem stayed writable |
+| time to steady | the box never left steady — **26 containers before, 26 after**, none restarted |
+| alarm fired / true? | **none fired**, checked twice independently after the fill was released |
+| should have fired, did not | `disk_critical` is defined at ≥95 % used and the disk sat at **96 % for ten minutes**. **But this is the ladder working as designed, not a miss:** the fill-watch is a daily sweep (03:30) plus one check ~90 s after a controller start. Predicted before the round, confirmed after |
+
+**Household loop: 12 operations, 0 failures.** The household kept using its apps normally throughout.
+
+**The finding is the silence.** The honest answer to „would the household be told their disk is
+full?" is **no** — unless the controller happens to restart while it is full. Here the timing was
+almost comic: the controller restarted at 21:28 after round 2's power cut, so its one opportunistic
+check ran about twenty seconds *before* the disk filled, and the next is not due until 03:30.
+
+**A correction, recorded where it happened:** I twice labelled a mid-window reading „end of window",
+estimating the clock instead of reading it. The readings were unchanged, but „nothing yet, five
+minutes in" and „nothing in the whole window" are different findings. From here the end-of-window
+check is taken when the round's own runner reports completion.
+
+### Round 4 — `offsite-run` (mealie) / accident: **tunnel killed for ten minutes**
+
+**The drawn ACTION never ran.** The runner aborted with „no session — mine, not the product's":
+round 2's power cut had rebooted the guest, `/tmp` is cleared on boot, and the dashboard password
+file lived there. Round 3 was a `use` round and never needed it, so round 4 was the first to find it
+gone. **The accident was measured; the off-site run was not.** Recorded as half-measured rather than
+re-run and presented as whole — re-running a round after seeing it fail is how a drill starts
+choosing its own results. The file now lives in `/root`, which survives a reboot.
+
+| the five things | |
+|---|---|
+| what the customer saw | from outside, the apps vanished for ~90 s (public route **530**) and came back on their own (**200**); from inside the house, nothing — traefik answered **301** throughout |
+| what the box did by itself | **repaired its own tunnel.** cloudflared killed 21:41:33Z, running again **21:43:07.478Z (~97 s)**, with `RestartCount=0` — so Docker's `unless-stopped` policy did *not* do it; the controller's protected-infra recovery redeployed it („[infra] deploying cloudflared →…") |
+| time to steady | the apps never stopped; the way IN was restored in **~97 s** |
+| alarm fired / true? | **two, correctly paired** — `health_critical` (error) 21:43, `health_recovered` (info) 21:48. Exactly what the ladder predicts for a missing protected container, and **the alarm was not a dead end** |
+| should have fired, did not | none for the accident |
+
+**Household loop: 10 operations, 0 failures — and that number is narrower than it looks.** The loop
+does not follow redirects, so it measures „is the app serving on the box", never „can the household
+reach it from outside". It saw nothing while the public route was returning 530.
+
+### Round 5 — `use` privatebin / accident: **docker restarted inside the guest**
+
+| the five things | |
+|---|---|
+| what the customer saw | a gap well under a minute: 200 before, **404** two seconds after docker returned (traefik had not re-registered routes), serving again by 21:54:19Z — about **40 s** of shut doors |
+| what the box did by itself | everything. Restart ran 21:53:27Z→21:53:41Z; **all 26 containers back at t+16s**; the controller returned with them, waited 51 s for the fleet to settle and found **nothing boot-orphaned to repair** — correct, since every container had already come back on its own policy |
+| time to steady | **16 s** to 26 of 26 containers; **~40 s** until the doors served. The slower number is the one a household feels |
+| alarm fired / true? | **`controller_started` (info) — true and correct**, and the only line the ladder expects: no `app_start_failed` (90 s boot grace), no liveness alarm |
+| should have fired, did not | **none** |
+
+**Household loop: NOT SAMPLED** — 0 lines, because the round lasted ~18 s and the loop samples every
+2 minutes. Recorded as not sampled, never as a pass.
+
+**A trap avoided.** The round's own alarm snapshot was taken **six seconds** after the controller
+started, and from it `controller_started` looked missing. A later reading shows it present at 21:53.
+An alarm cannot be called missing by a measurement taken before it could have fired.
+
+### Round 6 — `backup-system` (whole-guest backup) / accident: **none** (control round)
+
+| the five things | |
+|---|---|
+| what the customer saw | their apps went away and came back: during the backup **4 of 26** containers were up and every app answered **404** publicly; all 26 were serving again by 22:01:13Z. No banner, no mail — correctly |
+| what the box did by itself | quiesced the apps, snapshotted, ran the local tier, **failed** it, announced the failure with a retry schedule, then ran the **off-site tier from the snapshot with the apps already back up** — 21:59:54Z → **22:08:27Z (~8½ min)**, encrypted to ep0, taking **no local disk at all** |
+| time to steady | apps down ~21:55:30Z → 22:01:13Z ≈ **5m43s** — **contaminated by my own intervention** (I killed the local leg at 21:59:45), so it is an upper bound on the quiesce window, not a clean measurement |
+| alarm fired / true? | **`whole_guest_backup_failed` (error) — true, and better than true:** „Whole-guest backup FAILED on the **local tier** — retrying with backoff (next attempt in 15m0s)". It names the tier, not „the backup", and says what it will do next. The status surface agreed (`target_id:"local"`, `success:false`, `size_bytes:0`). **No alarm for the 22 apps it stopped** — correct, those stops are suppressed |
+| should have fired, did not | **none** |
+
+**The finding to carry forward:** a whole-guest backup on this box **cannot use its local tier** — a
+~29 GB source into a 14 GB root filesystem — and the product handles that honestly: it fails the tier,
+says which tier, schedules a retry, and still gets the data out of the house on the off-site tier.
+The local tier will keep retrying and keep failing on a box shaped like this one.
+
+**My intervention, and the correction it needed.** I killed the local leg when two samples showed `/`
+falling at ~16 MB/s with 3.6 GB left — under four minutes from wedging the nested PVE. The arithmetic
+stands, but I first wrote „I stopped the backup", which was wrong: I stopped **one leg**, and the
+off-site leg started by itself seconds later and succeeded. Counted as an intervention either way.
+
+### Round 7 — `use` nextcloud / accident: **internet cut for ten minutes**
+
+*Drawn as `update`; ran as `use`, because the catalog bump was never pushed — the catalog gates
+returned INCONCLUSIVE and undetermined is never a pass. Decided and recorded before the round, not
+after it.*
+
+| the five things | |
+|---|---|
+| what the customer saw | **depends where they stood.** At home: nothing — traefik answered `301` throughout and every app kept serving. Away from home: ten minutes of nothing — the public route gave **502**, then **200** about a minute after the block lifted |
+| what the box did by itself | kept all **26** containers running, needed no repair, and re-established the way in unaided: 530 three seconds after unblocking, **all four apps 200 by 22:21:52Z — ~64 s** |
+| time to steady | the apps never left steady; only the path in broke and healed, in **~64 s** |
+| alarm fired / true? | **none, and none should have** — the ladder puts `node_stale` at 30 minutes and this was ten. Nothing false was raised either |
+| should have fired, did not | **none** |
+
+**Household loop: 10 operations, 0 failures — narrower than it looks.** It does not follow redirects,
+so it measured the box (up throughout) and was blind to the public outage.
+
+**The question this round was meant to answer, and honestly did not.** Are alarms raised while the hub
+is unreachable retried and then silently dropped? **Not exercised.** The box reports every **15m0s**
+(measured: 21:53:49Z, 22:08:43Z) and the cut fell entirely between two reports — the next was due
+~22:23:43Z, after it lifted. Nothing was attempted, so nothing could be lost. Recorded as *not
+exercised*, never as *passed*.
+
+**The fence held, and it was checked against a baseline taken beforehand.** The accident flips a
+host-wide sysctl on demo-hp and inserts two `physdev` rules. Afterwards: `-P FORWARD ACCEPT`, **0**
+physdev rules, sysctl **0** — identical to the pre-round reading. demo-hp also carries guests 9201
+and 9202, so an abandoned rule would have been a fence breach, not an untidy drill.
+
+### Round 8 — `backup-app` nextcloud / accident: **internet cut for ten minutes**
+
+**22:35:48Z–22:47:59Z.** The app-data backup ran first and finished in 1 m 55 s
+(`db_dump` count 5, `success:true`, 22:37:48Z). The cut began six seconds later, so the two barely
+overlapped — and would not have interacted in any case: `backup-app` is the **local** app-data tier
+and needs no internet. The off-site tier is a different action.
+
+| the five things | |
+|---|---|
+| what the customer saw | **Nothing at home.** Every front door kept serving on the LAN for the whole ten minutes. From outside the house the sites were unreachable — the public path was down. 26 apps up before, 26 after, never fewer. |
+| what the box did by itself | Kept every container running, kept backing up, kept reporting to the hub, and rebuilt the public path unaided when the link returned. No restart, no intervention, noaction from me. |
+| time to steady | **≤43 s** after the link returned (public doors 200 again at 22:48:38Z). Containers never left steady at all. |
+| alarm fired / true? | **none fired, and none should have** — `node_stale` is a 30-minute threshold and this was ten. Nothing false was raised. |
+| should have fired, did not | **none** |
+
+**And the finding of the round is against my own instrument, not the box.**
+
+The hub report due at **22:38:43Z fell inside the cut** — and it **succeeded**:
+„Hub report pushed successfully (15526 bytes)". It succeeded because `hub.felhom.eu` resolves to
+**192.168.0.192**, a LAN address (measured from both the guest and the host), and my injector blocks
+everything **except** the LAN. So the accident named „internet gone" only ever removed the **public**
+path. The box never lost the hub, in round 7 or in round 8.
+
+Two consequences, both stated plainly:
+
+1. **The dropped-event question is still unmeasured** after two rounds that appeared to measure it.
+   Events pushed while the hub is unreachable are retried three times and then dropped permanently,
+   with no queue — that behaviour has still never been seen live.
+2. **My own memory file carries this exact warning** („hub.felhom.eu resolves to the LAN here; an
+   internet-cut drill must block it too") and I did not apply it. A warning that is written down and
+   not read is worth nothing, which is the same class of failure as an unread alarm.
+
+The injector is corrected for round 9's drawn internet cut so that the hub address is blocked too —
+**from the VM's side, at the host's tap rule.** The hub itself is never touched; the fence is kept.
+This is a repair to a broken instrument, not a re-draw: the drawn action, app and accident for every
+remaining round are unchanged.
+
+**A sixth mistimed reading, and the fix is in the runner now.** The round's own AFTER step read the
+public doors **three seconds** after the unblock and reported 530 on all four. That reading could
+never have been fair. The re-measurement 43 s later read 200 on all four. The runner measured the
+recovery before the recovery could begin — so the runner is the thing that gets fixed, not the note.
+
+### Round 9 — `use` uptime-kuma / accident: **internet cut for ten minutes, hub included**
+
+**23:00:50Z–23:12:00Z.** The first cut of the night that really removed the hub. The injector was
+corrected between rounds 8 and 9; the drawn action, app and accident were **not** changed.
+
+| the five things | |
+|---|---|
+| what the customer saw | **Nothing at home.** uptime-kuma answered 200 on all three reads during the action, and all four front doors read 200 at both post-accident readings. 26 apps before, 26 after, never fewer. |
+| what the box did by itself | Kept every container running while it was cut off from the hub **and** from its own host agent. Built its report on schedule, tried to push it **three times over 1 m 40.8 s**, gave up, and carried on serving. Both links repaired themselves the instant the block lifted — no restart, no repair action, nothing from me. |
+| time to steady | The apps never left steady. The doors read 200 at the first reading, **2 s** after the unblock, and again 63 s later. |
+| alarm fired / true? | **none fired, and none should have** — `node_stale` is a 30-minute threshold. Nothing false was raised. |
+| should have fired, did not | **none** — but see the near-miss below, which is a finding in its own right. |
+
+**What a lost report costs: measured, not assumed.**
+
+```
+23:08:42 [INFO]  [scheduler] Running job: hub-report
+23:08:42 [INFO]  [report] Building system report
+23:10:23 [WARN]  [report] Push failed: … context deadline exceeded
+23:10:23 [ERROR] [scheduler] Job hub-report failed: hub push failed after 3 attempts (took 1m40.813s)
+```
+
+Three attempts, then it stops. Nothing is queued. It gave up **31 seconds before** the link returned.
+And that is correct: a report is a **snapshot**, so a lost one costs nothing — the next snapshot
+carries the same truth, and the controller says so itself („backing off (the 15-min cycle still
+reconciles)"). **This is not the event path.** A dropped event is a lost *fact*, not a stale copy of
+a picture that will be redrawn. No event happened to be raised during the cut, so the event-drop
+behaviour is **still unmeasured** after three rounds of internet cuts.
+
+**And it came back by itself, on schedule.** The very next scheduled report went through —
+**23:23:43Z, „Hub report pushed successfully (15354 bytes)”** — exactly 15 minutes after the
+cycle that failed, and nothing was done to the box to achieve it. The reading was taken at
+23:24:21Z, deliberately *after* the report was due, so it could not be premature. So the whole
+shape of a hub outage is now measured end to end: build → three attempts → give up →
+keep serving → next cycle succeeds → no alarm, no loss.
+
+**The near-miss, which is luck and not design.** Last good report 22:53:43Z; next scheduled
+23:23:42Z; `node_stale` trips at 30 minutes. The gap is **29 m 59 s**. The staleness threshold is
+exactly twice the report cadence, so **a single failed push spends the entire budget** — one second
+of ordinary jitter and the operator is paged about a box that was healthy throughout and had already
+repaired itself. Filed as a register row.
+
+**A second fidelity fault in my accident, named like the first.** The cut also severed the controller
+from its host agent (`GET /backup/tiers` to the link-local `169.254.253.1` timed out twice). In a
+real house an ISP outage does not do that — controller and agent share one machine. So „internet
+gone" as injected is **broader than its name**: internet, hub *and* local agent. No further internet
+cuts are drawn, so the injector stays as it is and this caveat travels with rounds 7, 8 and 9.
+
+### Round 10 — `restore` uptime-kuma / accident: **hard reset, four seconds into the restore**
+
+**23:26:06Z–23:29:46Z.** The roughest pair drawn. The restore was accepted at 23:26:08Z
+(302, „Visszaállítás elindítva"); the reset button was pressed at 23:26:12Z, mid-write.
+
+| the five things | |
+|---|---|
+| what the customer saw | They pressed restore, were told it had started, and **four seconds later the whole machine went dark.** About two minutes of nothing. Then every app was back and every front door answered. **Nothing ever told them what became of the restore.** |
+| what the box did by itself | Booted, and brought **26 of 26 containers** back with no help. Boot reconciliation named the one app it had to recover („1 app(s) recovered in 1 attempt(s): [paperless-ngx]"), sent a startup hub report at 23:28:26Z, and settled its health probes. No intervention. |
+| time to steady | **150 s** — 0 containers at t+12 s, 25 at t+133 s, 26 at t+150 s. Doors 200 at both readings (23:28:42Z and 23:29:44Z). |
+| alarm fired / true? | **one, true** — `controller_started` (info). Exactly what the ladder expects after a reboot. No false alarm. |
+| should have fired, did not | **none from the alarm ladder** — but the restore silence below is a legibility gap, filed as a row. |
+
+**The restore left no trace anywhere, and the product has no place to leave one.** Four candidate
+status endpoints all 404 (`/api/restore/status`, `/api/backup/restore/status`,
+`/backup/restore/status`, `/api/restore`). `/api/backup/status` carries no restore field at all.
+On the pages, the only restore text is a **button label** and a JavaScript label expression. On disk,
+in the real data directory, there is no restore, lock or state file anywhere — and **no file at all
+was modified in the reset window**. An interrupted restore and a restore that never happened are
+indistinguishable, to the customer and to me.
+
+**CORRECTION, 00:24Z — the paragraph above is wrong and stays visible so the correction is too.**
+The four endpoints I called were four I **guessed**, and all four were wrong. The real route, read
+out of the restore page's own JavaScript, is **`/api/backup/restore-status`**, and it exists:
+`{"ok":true,"data":{"running":false,"started_at":"0001-01-01T00:00:00Z"}}`. So a restore status
+surface **does** exist. What is true — and is the better finding — is that after the reboot it is
+**blank**: `started_at` is the Go zero value, and the payload carries no `last` field at all, while
+the page's own script renders „<operation> sikertelen." from `st.last.message`. **The restore record
+is in-memory only and does not survive the machine stopping** — precisely the case a hard reset
+creates, and precisely when a household would want to be told. The register row is corrected to say
+that instead. I found the real routes by asking the controller for its own rendered links, which is
+what I should have done before filing anything.
+
+**The limit of that measurement, stated rather than glossed.** Only four seconds elapsed, so the
+restore may have finished or may never have written a byte — and I cannot tell, because the
+controller's log stream holds **zero lines before 23:28:00Z** (a reset starts it fresh) and the debug
+ring died with the machine. What is independently verifiable is the **absence of any restore record**,
+and that is what is filed; it holds however far the restore got.
+
+**Four of my own instruments failed in this round, and all four are recorded in the evidence:** a
+claim that was unfalsifiable when written; an on-disk check against a directory that does not exist;
+a household count that reported 0 lines and 0 failures when the truth was one line and it *was* a
+failure; and a disk guard that reported „active" all night while being a **transient** unit that
+vanished at the reset. It is now file-backed and enabled, and its script has been copied off the box.
+
+### Round 11 — `use` paperless-ngx / accident: **the data drive pulled out for twenty minutes**
+
+**23:50:49Z–00:13:09Z.** The drive was detached from the **running** box at 23:50:54Z and put back at
+00:10:58Z. This is the round that produced the most alarms of the night, and every one of them was
+true.
+
+| the five things | |
+|---|---|
+| what the customer saw | **The four apps whose files live on that drive stopped** — Paperless, Jellyfin, Nextcloud, Immich — and Paperless's front door went 404. The other eleven apps kept serving normally throughout. About twenty minutes later everything was back, roughly a minute after the drive was plugged in again. |
+| what the box did by itself | Noticed the drive had gone and **named it by the label the household sees** („Adatlemez"), named **each** broken app individually, degraded its own health, waited, noticed the drive return, restarted the apps and recovered its health. No restart, no repair, nothing from me. |
+| time to steady | **67 s after the drive returned** (26 containers again at 00:12:05Z). The door followed at 00:13:06Z. |
+| alarm fired / true? | **eight, all true, correctly paired at both ends** — `storage_disconnected` (error) → four `app_start_failed` (warning) → `health_degraded` (warning) → `storage_reconnected` (info) → `health_recovered` (info). The four apps named are **exactly** the four with data on the pulled drive. Nothing false was raised. |
+| should have fired, did not | **none** |
+
+**The alarm that looked missing, and was not.** The round's own snapshot at 00:13:08Z showed
+`health_degraded` with no recovery — which would have been the first missing alarm of the night. The
+recovery fired at **00:13**, and the snapshot missed it by **seconds**. A re-read at 00:14:13Z, taken
+after the apps were back, found it. This is the discipline from the earlier mistimed readings earning
+its keep: when a measurement could have been early, it is re-taken rather than turned into a verdict.
+
+**The drive came back clean** — `/dev/sdd`, 98 G, 2 % used, mounted at `/mnt/felhom-drives/hdd_1`,
+with the guest's mountpoint config unchanged, 26 containers up and every real front door serving.
+
+### Round 12 — `use` paperless-ngx / accident: **nothing** (closing control round)
+
+**00:15:48Z–00:16:55Z.** The night's last round, drawn as a control.
+
+| the five things | |
+|---|---|
+| what the customer saw | Nothing at all. The app answered 200 on all three reads, and every front door answered 200 at both readings. |
+| what the box did by itself | Nothing needed doing. 26 containers before and after. |
+| time to steady | **1 s** — it never left steady. |
+| alarm fired / true? | **none, and none should have.** The newest entry in the feed is still round 11's `health_recovered` at 00:13. |
+| should have fired, did not | **none** |
+
+**Checked rather than assumed:** `inject.sh` has no „nothing" case — its default branch exits 2 on an
+unknown accident. The control rounds never reach it, because the runner handles the no-accident case
+itself and says so („accident: none — control round, deliberately"). This matters because *a broken
+injector produces exactly the same result as a control round*, and the only way to tell them apart is
+to look at which code path ran.
+
+**What the closing control round is worth.** It shows the quiet is real: after eleven rounds of power
+cuts, resets, full disks, severed networks and a drive pulled out of a running machine, a round in
+which nothing was done produced nothing — no alarm, no restart, no drift. The alarm feed is not
+simply noisy.
+
+## Phase 2 — the morning after
+
+**Every app answered through its own front door.** All twelve real names, measured at 00:19:16Z —
+`cloud`, `inventory`, `media`, `paperless`, `paste`, `photos`, `recipes`, `share`, `status`,
+`travel`, `vault`, `wiki` — **200 on the public path, every one**. And healthy is not inferred from
+a door: all **26 containers** report `Up … (healthy)`, except `traefik` and `cloudflared`, which
+carry no healthcheck and show a bare `Up`. The four showing seven minutes are the drive-backed apps
+restarted after round 11.
+
+**The off-site restore could not be done, and two independent instruments agree why.** The brief asked
+for one DB-backed app restored from off-site onto scratch 9202. It has nothing to restore from:
+
+| instrument | answer |
+|---|---|
+| `restic`, with the box's own key, password file and `known_hosts` | `Fatal: wrong password or no key found` — exit status **1**, read from restic itself rather than from the end of a pipeline |
+| the product's own status surface, which is what a customer sees | `{"orphaned":true, … ,"snapshots":0,"status":"error"}` |
+
+The repository is orphaned **because this box is a rebuild for an existing customer**: on a rebuild
+the restic password is minted fresh, so snapshots written under the old one can never be opened
+again. That is a known, documented shape, and **the product surfaced it honestly** — the true
+`offbox_repo_orphaned` alarm of round 1, mailed to the operator within two seconds of the run.
+
+**What did leave the house.** The *whole-guest* off-site copy is a different store and it worked: ep0
+holds two intact snapshots for this box, including tonight's at **21:59:54Z** — round 6's off-site
+leg, the one that started by itself after I killed the local leg. Its file index is roughly four
+times the afternoon copy's, consistent with a guest by then carrying twelve apps. **Stated as a
+limit:** that is a *listing*, not a verification. A PBS verify job would prove restorability and it
+**writes** verify state, so it was not run — ep0 is read-only for evidence tonight.
+
+**The household loop.** 204 probes from 21:06:30Z to 00:18:10Z. Seven lines flagged as failures, of
+which **only two are real events** — `wiki` during round 2's power cut and `cloud` during round 10's
+hard reset, each a single sample, each healed before the next probe. The other three were **my own
+classifier** counting a 301 redirect as a dashboard failure; the log carries that correction in its
+own words at 21:11:25Z and the wrong lines were left in place so the correction stays visible. Ten of
+the twelve rounds left **no mark at all** in this log, including the twenty minutes with the drive
+pulled — the loop samples each name every two minutes, so that silence is the instrument's sampling
+rate and **not** evidence the household saw nothing.
+
+**The catalog bump: verified reverted, not remembered.** Clean tree, local exactly level with
+`origin/main` (0 ahead, 0 behind), the nextcloud template still on its original `redis:7-alpine` pin
+and `catalog_since: "2026-07-18"`, newest commit 2026-09-15. The bump was prepared, **refused by the
+catalog's own gates** (image-resolvable and volume-persistence both INCONCLUSIVE — its own canary
+failed, so the verdict was UNDETERMINED, never a pass) and reverted before any push.
+
+**And one delivery proof the truth table could not give.** The mailbox shows every alarm **arrived**
+at the operator, not merely that it was stored — round 11's whole set, round 6's tier-naming backup
+failure, round 1's orphan warning, the OOM, the deploy failure and my own thin-pool `storage_fill_critical`.
+In a project where 91 events once sat in a database having e-mailed nobody, *raised* and *delivered*
+are two different claims, and only one of them had evidence before tonight.
+
+## Interventions — counted, with the reason for each verdict
+
+**One.** At 21:59:45Z in round 6 I killed the **local leg** of the whole-guest backup. The arithmetic
+that forced it: a ~29 GB source being written into a 14 GB root filesystem at ~16 MB/s, i.e. under
+four minutes to a full `/` on the nested host, mid-round. What it cost: a leg that could never have
+succeeded. What happened next without me: **the off-site leg started by itself from the same snapshot
+and succeeded in about eight and a half minutes.** Filed as **R-548**.
+
+My first note on it said „I stopped the backup". That was wrong and is corrected in the evidence: I
+stopped **a leg** of it, and the box completed the other one unaided.
+
+**Both pre-declared presses went unused.** O1, the „Send self-bind link" button, was not needed —
+the automatic mail was already waiting (18:17:46Z) and the box bound with **zero** operator presses.
+O2, „Re-issue PBS credentials", was not needed either — the acknowledged-delete path re-issued them
+by itself (`pbsdr_auto_reissue`, 20:19Z). **Both prompt claims they were insurance against turned out
+to be true**, and the F-14 path was measured live for the first time.
+
+**Counted separately, because it is not a round result:** Phase 0's seeding repairs. I filled the LVM
+thin pool to 100 % by firing twelve deploys at once, then repaired the damage — a guest restart to
+clear an `emergency_ro` remount, dropping corrupt image layers, a remove-with-data and one consistent
+re-deploy after a re-seed minted fresh database passwords over initialised volumes, and a rewritten
+`APP_KEY`. **The damage was mine, not the product's**, the product's behaviour throughout was correct,
+and every repair went through the product's own endpoints rather than by hand-running compose. Listed
+in full in `evidence-chaos-night-2026-09-17/interventions.txt` so the distinction is visible rather
+than convenient.
+
+**Not counted, and why:** acts on my **own instruments** — moving the dashboard password after a
+power cut cleared `/tmp`, rewriting the injector and the runner, re-creating the disk guard as a real
+unit. Counting those would flatter the night in one direction and pad the stop-rule count in the
+other. **Round 4 is the clearest case of declining to intervene:** the tunnel was left dead on
+purpose — „NOT restarting it by hand — whether it returns by itself IS the measurement". It
+returned by itself in 97 s.
+
+**Standing against the stop rule: 1 of 4.** The night ran its full twelve rounds.
+
+## Teardown — three layers, stated
+
+**Machine — gone.** VM 336 stopped and destroyed with all three disks purged (00:35:25Z), gated on
+its **name** rather than its number because two standing guests share the host. `qm list` shows no
+VMs; `/mnt/hdd_1/images/336` no longer exists. The storage was verified to *be* `/mnt/hdd_1` from its
+own definition (`nvme-scratch`, `path /mnt/hdd_1`, `is_mountpoint yes`) rather than assumed. The
+machine had **three** disks, not the two the brief asked for — the third was mine, added in Phase 0
+after I filled the thin pool — and that is recorded rather than quietly removed.
+
+**Host — clean, measured before and after.** `nvme-scratch` 6.78 % → **1.61 %** (~48.5 GB returned);
+`local-lvm` **unchanged at 44.75 %**, so the fence that said *never local-lvm* held; free space on
+`/mnt/hdd_1` 827 G → 875 G. Guests 9201 and 9202 still running. The household loop and the disk guard
+were stopped and disabled **after** their logs were copied off (the guard's log was 0 bytes — it
+never fired). Firewall back to `-P FORWARD ACCEPT` with **0** physdev rules, so none of the three
+network accidents left a rule behind. Scratch 9202: **nothing to remove**, shown rather than said —
+three infrastructure containers, no app deployed, no stack touched since 21:00, no off-site config.
+
+**Hub — host record deleted through the acknowledged flow.** The first attempt at 00:38:37Z was
+**correctly refused** (409, „Host is ONLINE") — the box had died inside the hub's liveness window. The
+acknowledged delete went through at **07:25:13Z** (`confirm_host_id` + `delete_escrow=1` → 303). Every
+line of the after-state written down *before* the act matched: the host answers 404; `drill-r50`,
+both demo hosts and the `tester-1` **customer** still answer 200; the customer now lists zero hosts.
+**The automatic connect mail arrived two seconds later** (07:25:15Z, „Kösd össze a Felhom dobozodat"),
+quoted in full with its token redacted in `teardown-hub.txt` — and it is provably tonight's, because
+the mailbox held no such mail newer than 18:17:46Z when checked at 00:38Z.
+
+**Why the hub layer finished six hours late — my fault, not the product's.** The retry was guarded
+by „don't post while the host page contains ONLINE". That word lives in a JavaScript string that is
+**always** on the page, so the guard could never pass. It refused six times and gave up at 01:20Z,
+while the hub's structured answer would have said `"status":"down"` from about 00:54Z. Nothing ran
+again until 07:24Z.
+
+**ep0 — backups stayed, nothing removed.** Read three times: 00:17:15Z, 00:36:52Z (just before the
+delete) and 07:25:35Z (after). Identical every time — three namespaces, two snapshots each, six in
+total, 16 G used. No prune, no verify, no write.
+
+## Claims in the prompt that turned out wrong — named first, as asked
+
+**The two the brief itself flagged both turned out TRUE, and both were checked tonight rather than
+assumed.**
+
+1. **„The automatic mail is waiting in the mailbox."** The brief warned this had been read from
+   *yesterday's* host delete and not verified. **It was true.** The self-bind mail of **18:17:46Z**
+   was in the mailbox, and the box bound with **zero operator presses** — so the pre-declared press
+   O1 was never needed.
+2. **„The WG hook provisions by itself after an acknowledged delete" (the F-14 path).** The brief
+   noted this had never been measured live. **It was true, and it was measured live for the first
+   time:** `pbsdr_auto_reissue` at **20:19Z** — „Previous key destroyed (acknowledged deletion) —
+   credentials re-issued automatically." The second pre-declared press, O2, was never needed either.
+
+**Now the ones that were wrong.**
+
+3. **WRONG: „restore one DB-backed app from off-site onto scratch 9202."** It could not be done at
+   all on this box, and not because anything broke. This box is a **rebuild for an existing
+   customer**, so its restic password was minted fresh and the snapshots already in the remote store
+   can never be opened by it again. Two independent instruments agree: `restic` itself
+   (`Fatal: wrong password or no key found`, exit 1) and the product's own status
+   (`orphaned:true, snapshots:0, status:"error"`). The brief assumed an off-site app repository this
+   box could open; on a rebuild fixture there is none.
+4. **WRONG in effect: „a system disk + one data disk."** The machine ended the night with **three**
+   disks. The third, 64 G, was added by me in Phase 0 to extend the LVM thin pool after I filled it
+   to 100 % by firing twelve deploys at once. **The deviation is mine, not the brief's**, but the
+   fixture was not the one the brief described and saying so is the point.
+5. **WRONG: round 7's drawn action `update` was not performed as drawn.** The catalog's own gates
+   returned `image-resolvable INCONCLUSIVE` and `volume-persistence INCONCLUSIVE` — its **own canary
+   failed**, so the verdict was UNDETERMINED, which is never a pass. The round ran `use` instead. A
+   deviation from the drawn schedule, logged rather than quietly substituted.
+6. **WRONG, and mine rather than the brief's: „an internet cut tests what happens when the hub is
+   unreachable."** The accident's *name* implies it; on this network it was false. `hub.felhom.eu`
+   resolves to a **LAN** address here, and my injector allowed the whole LAN — so rounds 7 and 8 cut
+   the public path only, and the box never lost the hub. My own memory file carries that exact
+   warning and I did not apply it. Fixed between rounds 8 and 9 by blocking the hub address **from
+   the VM's side**, which is what finally made round 9 the measurement it was supposed to be.
+7. **WRONG as a description of the night's clock: the schedule table's times.** The table drawn from
+   the seed lists rounds at 23:30 through 04:05. Those were **nominal**. The real spacing was 25
+   minutes from each round's actual start, and the night's twelve rounds finished at **00:17Z**,
+   roughly four hours earlier than the table's own column suggests. Each round's real timestamps are
+   recorded in its own section; **the drawn order, apps and accidents were never changed** — only
+   the wall-clock the table guessed at.
+
+**And one the brief did not make, which the night could not answer.** Events pushed while the hub is
+unreachable are retried three times and then dropped permanently, with no queue. Three ten-minute
+hub outages happened and **no event was raised during any of them**, so that path is still
+unmeasured. What *was* measured is the **report** path: built, three attempts over 1 m 40.8 s, given
+up, and the next scheduled report succeeded — and a report is a snapshot, so nothing was lost.

+# DRILL — R-389: only the first broken app per hour reached the operator (2026-08-23)
+
+**Hub v0.107.0 → v0.108.0. No controller release, so no golden and no floor.** Live leg on `demo-hp`
+(Tier 0) plus the hub. UNATTENDED. Method: the hub's own SQLite records plus the controller log.
+Guest and hub DB are UTC; the hub pod logs CEST.
+
+**No halt condition fired.**
+
+## The pair that says it
+
+Same box, same shape — two apps down four minutes apart, inside one hour:
+
+```
+2026-08-23 09:27:51  sent        BookStack     <- v0.107.0
+2026-08-23 09:31:51  suppressed  PrivateBin        operator cooldown 1h, key=demo-hp:app_start_failed
+
+2026-08-23 11:56:57  sent        OpenGist      <- v0.108.0
+2026-08-23 12:00:57  sent        Calibre-Web
+```
+
+**2 sent / 0 suppressed**, where the day before the identical shape gave one of each.
+
+And the keys, from the hub's own suppression rows — it records the key only when it declines:
+
+```
+operator cooldown 1h, key=demo-hp:app_start_failed:opengist
+operator cooldown 1h, key=demo-hp:app_start_failed:calibre-web
+```
+
+against v0.107.0's shared `key=demo-hp:app_start_failed`.
+
+## The fence, and why it is not decoration
+
+`crossdrive_failed` is severity `error`, reaches the operator leg, and carries `stack_name` — through
+`CrossDriveDetails`, **a different struct from `AppDetails`**. A rule of the form *"if the details
+carry a stack_name, split per app"* would have split it and silently undone R-182.
+
+Proven live: two different apps' `crossdrive_failed`, one minute apart →
+
+```
+sent        opengist
+suppressed  calibre-web    operator cooldown 1h, key=demo-hp:crossdrive_failed
+```
+
+**Byte-identical to the derived v0.107.0 key. No app suffix.** That is why `cooldownStackSuffix`
+takes the event type as well as the details, unlike its two siblings.
+
+## Part 2 — the burst, measured
+
+Three apps stopped in one scan (`kimai`, `romm`, `paperless-ngx`, none with a live cooldown — checked
+first, because a stale one would have halved the count and made the answer look better than it is):
+
+| | |
+|---|---|
+| attempted | **3** |
+| sent | **3** |
+| suppressed | **0** |
+
+**Judgement: per-app is the right grain, and this volume is acceptable.** The reference box has 8
+deployed apps, so a total outage is 8 mails; the boot grace (90 s), the quiesce grace (180 s) and the
+per-app edge trigger absorb reboots, backup cycles and persistently-dead apps. **No digest row was
+filed.** The reopening condition is stated rather than left implicit: it scales linearly with app
+count and has no ceiling, so a box large enough that a total outage is unreadable is the point at
+which the answer becomes a digest with a customer message — not a wider cooldown.
+
+## Part 3 — gate 11, and the spec discrepancy it forced
+
+The gate refuses a push whose `REPORT.md` carries an observation with neither `FILED: R-NNN` nor
+`NOT-A-FINDING: <reason>`.
+
+**The specification said an item may "cite an R-NNN that resolves". That rule would have passed the
+very item the gate was built to catch.** Yesterday's lost observation reads *"This is R-182's known
+cooldown-key shape…"* — `R-182` resolves, and it is cited as an **analogy**, not as the row that files
+it. No parser can tell citation-as-precedent from citation-as-filing by reading prose. The marker is
+therefore explicit, and the discrepancy is recorded in the gate's docstring rather than quietly
+resolved. `EDGE 7` in the evidence is that exact case, convicted.
+
+| Control | Expected | Observed |
+|---|---|---|
+| historical: yesterday's real section, verbatim | refuse | **exit 1**, naming both items |
+| plant an observation with no row | refuse | **exit 1** |
+| add the row | pass | **exit 0** |
+| remove the observation | pass quietly | **exit 0** |
+| `FILED:` a row that does not resolve | refuse | **exit 1** |
+| `NOT-A-FINDING:` with no reason | refuse | **exit 1** |
+| both markers on one item | refuse | **exit 1** |
+| section present, no numbered items | inconclusive | **exit 2**, saying what it could not read |
+| no `REPORT.md` at all | inconclusive | **exit 2** |
+| a bare `R-182` mention (the trap) | refuse | **exit 1** |
+
+## Evidence index (`evidence/`)
+
+| File | What it shows |
+|---|---|
+| `redproof-1-key.txt` | suffix dropped from the key → `1 operator mail(s), want 2`, and the live key shape reproduced |
+| `redproof-2-allowlist.txt` | allow-list removed → `crossdrive_failed`, `app_deployed`, `app_removed`, `backup_failed` all split per app |
+| `gate11-01-historical-redproof.txt` | yesterday's actual observations section, refused |
+| `gate11-02-three-controls.txt` | plant → refuse, file → pass, remove → pass |
+| `gate11-03-edges.txt` | seven boundaries incl. the R-182 trap |
+| `live-01`…`live-05` | Scenarios A and B: both sent, then each suppressed under its own key |
+| `live-06`, `live-07` | Scenario C: crossdrive stays coarse |
+| `live-08`, `live-09` | the burst, with its pre-check |
+| `live-10-full-controller-log.txt` | 1803 lines, pulled before the restore |
+
+## Teardown
+
+Nothing provisioned. Five apps were stopped across the walk (`opengist`, `calibre-web`, `kimai`,
+`romm`, `paperless-ngx`) and **all were restarted and confirmed healthy** — 17 containers up. No app
+was rebuilt, redeployed or restored; the three retained subjects (`docmost`, `bookstack`,
+`privatebin`) were not touched at all.
+
+**Hub-side, stated explicitly.** The hub was written this session: deployment to v0.108.0 via the
+manifest, and **six probe events were POSTed to the live hub** for Scenarios B and C (two
+`app_start_failed`, two `crossdrive_failed`, plus the two from yesterday's Scenario H that were
+deliberately left in place). They are inert event rows for `demo-hp` and are named here rather than
+left to be found. **Every count in this drill is filtered by `created_at >= T0`** precisely so those
+rows cannot contaminate it. Nothing else: no appliance registered, no customer created, no artifact
+manifest changed, floor untouched.

+# DRILL — a stranger's first hour on 0.242.0 (2026-09-14)
+
+**Interventions a volunteer could not have made: 1** (I1 — reaching the dashboard at all).
+**Ready for a volunteer: NO — because no instruction tells a stranger where the installer is or what
+to type, and the link in the setup-code e-mail does not open for a new customer; either stops them
+before their first app.**
+
+Evidence: `evidence-drill-fresh-install-0242-2026-09-14/` — `journal.md` (every observable, in
+order), `screens/` (installer and console, codes redacted), `box-logs-phase1/`, `A1-power-cut.txt`,
+`step10-remove-observe.txt`. Golden: `../tests/golden-0.242.0-2026-09-14/`.
+
+---
+
+## 1. What held, in one table
+
+| # | step | result | time |
+|---|---|---|---|
+| 0.1 | golden 0.242.0 baked, round-trip verified, vouched | **PASS** | bake ≈6 min |
+| 0.2 | customer-facing instructions exist | **FAIL — none exist** (R-493) | — |
+| 1 | download the installer | PASS — but only with the exact file name; the site has no index (R-493) | 32 s, sha matches |
+| 2 | install | PASS with **four unanswered questions**, one of which refuses its own default (R-495) | ≈12 min at the keyboard, 3 m 24 s copying |
+| 3 | first screen, pairing, claim | box registered in 86 s; console sends a stranger to the Proxmox admin page and misnames the passphrase (R-496); passphrase is delivered by nothing (R-497); **the dashboard has no address** (R-494, **I1**); claim itself < 1 s | power-on → claimed 27 m 37 s |
+| 4 | "ready", version | **PASS** — landed on controller 0.242.0 + agent 0.130.0, the vouched set; no self-update needed | power-on → controller 4 m 14 s |
+| 5 | deploy BookStack + PrivateBin | **PASS** — 68 s and 21 s; pages honest about where data goes; first steps say literal `wiki.DOMAIN` (R-498) | |
+| 6 | use both through their front doors | **PASS** — BookStack login, password change, book, Hungarian page, 256 KiB attachment; PrivateBin encrypted paste, decrypted round trip | |
+| 7 | read the backups pages | mostly honest; **one page says „already in the PBS backup, nothing to do" on a box with no PBS** (R-499); „Következő mentés — 0 órája" reads backwards | |
+| 8 | backup now | **PASS** — dates move to the true time on both pages | 21 s |
+| 9 | version labels / Update | „Naprakész" true (installed == catalog); **no newer version offered — skipped** | |
+| 10 | remove with „delete my data too" | **PASS** — volume, backup folder and restore points gone, front door 404; response names each removal | 6 s stop + <1 s remove |
+| 11 | restore the other app | **DATA PASS** — deleted page and attachment back, sha256 identical, Hungarian intact | 32 s to healthy |
+| 12 | status pages a week later | dashboard shows the backup in UTC, backup pages in local time (R-500) | |
+| A1 | power cut | **PASS** — same versions, data intact, no alarm; one re-login | ≈2 min to dashboard |
+| A2 | typo in the code | **PASS** — typo refused, right code accepted after it; 5 failures lock 15 min with an honest Hungarian message; lockout mail goes to the operator only | |
+
+## 2. The intervention
+
+**I1 — the dashboard has no reachable address (R-494, P1).** The setup-code mail says
+`https://felhom.drill0242.felhom.eu`. That name has no DNS record; the hub never creates the
+Cloudflare tunnel or record (the token is a pasted, optional field); the box's own split-horizon
+resolver learns the name 3 m 46 s after the controller starts, but only a device that uses the box as
+its DNS server benefits, and nothing says so. The walk reached the dashboard at the guest's LAN address
+with the name forced. **Filed before it was performed.** It was performed once and covered every later
+dashboard and app request.
+
+**The stop rule (four) was not reached.**
+
+## 3. Harness substitutions — not interventions, and why
+
+These are things **this harness** could not do and **a volunteer could**, so they are not counted.
+They are listed because each one hides a part of the path from this walk.
+
+| | what | consequence for the claim |
+|---|---|---|
+| **H1** | **No mailbox.** Both customer mails go only to the registered address; the hub keeps hashes; the Resend key is send-only. | **The self-bind page was not exercised** — the operator's bind fallback was used. The setup code was minted box-side twice (`--print-reset-code`, generations 3 and 4) via the vaulted break-glass. **The mailed code and the self-bind link are unproven by this walk.** |
+| H2 | `qm sendkey` sends US scancodes; the layout was switched from Hungarian to U.S. English | Hungarian keyboard entry of the password and e-mail not exercised |
+| H3 | auto-reboot unticked, ISO detached by `qm set` | the "stick still in" reboot not exercised |
+| H4 | Terminal UI entry chosen over the graphical default | graphical installer not exercised this run |
+
+**Harness slips, recorded:** the first box-side code (generation 2) was captured with a pattern that
+does not match accented letters and was shredded unseen; the first template pick for the bake was
+arm64; two BookStack calls used wrong routes (405); one removal was called on a running app, which the
+screens never offer (409 — withdrawn as a finding); the A1 poll misread an expired session for 8 min;
+the monitoring banner and the restore-finish message were first read from server HTML and are script-
+rendered — both readings were corrected in the journal.
+
+## 4. Findings
+
+| row | rank | one line |
+|---|---|---|
+| **R-493** | **P1** | No customer-facing install instructions; the ISO site has no index. **Blocks inviting anyone.** Stopgap: `runbooks/VOLUNTEER-first-hour.md` |
+| **R-494** | **P1** | A new customer's dashboard has no address unless the operator hand-makes a tunnel — the setup mail's link is dead (**I1**) |
+| R-495 | P2 | The installer asks four unanswered questions and refuses its own default hostname |
+| R-496 | P2 | The console first tells a stranger, in English, to open the Proxmox admin page; calls the passphrase „a jelszavadat" |
+| R-497 | P2 | Nothing delivers the Tulajdonosi jelmondat, yet the mail says it was received at setup |
+| R-499 | P2 | „Already in the full system backup (PBS) — nothing to do" on a box with no PBS |
+| R-498 | P3 | 52 of 53 app pages say a literal `wiki.DOMAIN` |
+| R-500 | P3 | Dashboard shows the backup time in UTC, backup pages in local time |
+
+Observations, not filed: the deploy poll has no `degraded` branch (16 s of stale step text);
+„0 °C" beside „Nincs adat" for a virtual disk; the removal dialog mentions „éjszakai restic
+pillanatképek" on a box with no restic; the drive „attach" list offers the guest's own system volume;
+the launcher menu shows an English „Debug"; the lockout e-mail reaches the operator only;
+**R-214 still reproduces** (pairing banner and stale code on the console after bind).
+
+## 5. Scope and what this walk does NOT claim
+
+- **Not the recovery-after-rebuild journey.** The capability map's journey row (walk 5) is about a
+  rebuilt box recovering off-site data. This drill walked the **first hour**; it neither re-proves nor
+  contradicts that row, and the map is annotated to say so.
+- **DR tier off, off-site off.** The customer was created with the DR tier unticked (it provisions an
+  ep0 namespace; the brief fenced ep0). The off-site and escrow screens were therefore not walked.
+- **ep0 was touched anyway, by the product:** enrolment registers a WireGuard peer on ep0 for every
+  box (`wg registered … ip=10.77.0.5/32 … sync=ok`). The teardown removes it through the host delete.
+- **No browser.** Every screen was driven through the endpoint the page calls; script-rendered state
+  (restore-finish banner, host-metrics card) was not observed.
+
+## 6. Teardown — three layers
+
+See `REPORT-drill-fresh-install-0242.md` §Teardown for the measured before/after of each layer and
+the disposition of customer `drill0242`.
+
+Untouched, and checked: demo-hp guests **9201** and **9202** (running throughout), `local-lvm`, the
+demo-felhom box, DooPlex's services (only the bake VM, which is the accepted bake exception, reverted
+to `virgin`), ep0 beyond the product's own peer registration, and Peti's box.

+# DRILL — prove the P1 fixes on a fresh box (2026-09-16)
+
+**Interventions: 0** (O1 the operator's self-bind press and O2 the PBS re-issue press were pre-declared and are counted apart).
+**Ready for a volunteer: NO — and the reason is new, not one of the old ones.** Every P1 fix this drill set out to prove did hold on a fresh box. But a one-drive box with no off-site tier — the state every fresh install starts in — keeps **none of the household's own files in any backup**, while the backup page says it does, and a restore then reports success and leaves the app listing photos it cannot open (R-537, R-538).
+**The automatic connect e-mail: PASSED.** The host record was deleted at 12:22:59Z and the mail „Kösd össze a Felhom dobozodat” reached `tester1@felhom.eu` at **12:23:00Z — one second later**, with `selfbind_link_sent … (host delete)` on the customer timeline. The requirement was two minutes.
+
+> Baselines at start (re-verified against live Gitea): controller `383a30b3c07b` v0.243.0 (`Unreleased`: the
+> „0 B" tile fix), agent `e98b857684f4` v0.131.0, felhom.eu `351296114c4d` hub v0.114.0, catalog `94bc5febaca2`.
+> Golden before this run: 0.242.0 (2026-09-14). Customer `tester-1`, domain `enkicsifelhom.hu`, e-mail
+> `tester1@felhom.eu`, **no host**, DR tier ticked, ep0 token held with no descriptor, namespace EMPTY
+> (`phase3-ep0-before.txt`).
+
+## Phase 0 — rulings, the golden, the N100
+
+**Ruling 1 (2026-09-16, operator).** The signing keys stay on DooPlex, owner-only
+(`/mnt/5_hdd/felhom.eu/felhom-op-operational`, `felhom-rec-recovery`, `felhom_op_ed25519`, mode 0600);
+CC may sign `agent_update` jobs with them until the first PAYING customer — testers excluded. Recorded in
+`CONTEXT.md` and `04-control-plane-authorization.md` §3.1. **R-533 closes** (path + mode);
+**R-530 narrows** to "a fleet rollout step is still undesigned".
+
+**N100 signed and updated (R-530).** `felhom-opsign -op agent_update -host demo-felhom-8363b5 -key-id
+felhom-op-1 … -agent-version 0.131.0 -sha256 1118b552…c9c`, queued 08:51:34Z, **the box took it at
+09:04:43Z** (its own poll, ~13 min), dwelled 60 s and committed; `controller-supervisor: started`
+(interval 30s, confirm 2, crash-loop 3/15m) in its journal. Peti's box untouched. The N100 keeps
+controller 0.242.0; its floor was not moved by this run.
+
+**Ruling 2 — hub v0.115.0 (R-529).** `host_stale` / `host_down` / `host_recovered` join the `node_*`
+cooldown bypass with the same 5-minute dedupe. Red-proof: with the three host types removed the test fails
+at "host_stale 39 min after the previous one was suppressed (sent=1)". Recorded in `08-alarm-ladder.md` §6.2
+beside the 2026-09-15 node ruling. Deployed by GitOps: ArgoCD Synced, `deploy/hub` image 0.115.0.
+
+**Golden 0.243.0 baked and vouched.** First attempt FAILED and is recorded: the template picker took the
+LAST `debian-13` line, which is **arm64**, and the container would not start ("Detected container
+architecture: arm64"); no golden was produced, the scratch guest was destroyed and the disk reverted.
+Re-run with the amd64 template: `GOLDEN_VERSION=0.243.0`,
+`GOLDEN_SHA256=e2d1843c8b648910ddde7cef4fe9f9ba2ee25002cdb58fbc42543a3e8967c10a`. Markers from the saved log
+(`phase0-bake-full.log`, 326 lines): `docker OK (overlay2` ×1, `including mount point` ×2 (rootfs + mp0),
+`upload OK (HTTP 201)` ×1, `FATAL` 0, `excluding` 0. Token leak checks: control copy 1, committed log 0.
+Vouched as a three-field change — golden 0.243.0 + agent 0.131.0 + min agent 0.131.0 — hub logged
+`Artifact manifest set: agent=0.131.0 golden=0.243.0 min_agent="0.131.0" wrapper_sha=true`.
+
+## Phase 1 — the walk, as a volunteer
+
+| # | step | what happened | time (UTC) |
+|---|---|---|---|
+| 1 | download from `felhom.eu/letoltes` | the page names `felhom-installer-1.27.1-pve9.2-1.iso`, 1 705 322 496 B, sha256 `25637007…c053`; the downloaded file matched **byte-for-byte** | 08:55–08:56 |
+| 2 | install | boot menu default is the **graphical** entry (15 s). It IS drivable by keyboard (Tab moves focus, Enter presses), but each step needs a screenshot to see where focus is, so the walk switched to the **text-mode** entry — the other entry a volunteer is offered — and says so. Screens: EULA (English Proxmox), disk target **`/dev/sda 32 GiB` only** (the 100 GB data disk is never offered as the target), Hungary/Europe-Budapest/Hungarian prefilled (the keyboard was set to U.S. English **for typing only**), password + `mail@example.invalid` prefilled, host name prefilled `pve.example.invalid` (replaced with `tester1.enkicsifelhom.hu`), DHCP `192.168.0.128/24`, summary with **[X] Automatically reboot after successful installation** | 09:00–09:12 start |
+| 2b | the reboot trap, measured | the automatic reboot **re-entered the installer**: a guest reboot reuses the running process's boot order, so a disk-first change made during the install does not apply. A volunteer with the stick still in sees the installer again. Cold stop + remove the stick + start → boots the installed system | 09:57 |
+| 3 | first console screen | **Felhom-only, Hungarian, no admin URL** (`8006` 0 occurrences): „Felhom otthoni szerver … Ezen a gépen most nincs dolgod … Párosító kód: 37S-NFE … Nyisd meg az e-mailben kapott linket". The hub's Hosts page lists the same box as an unclaimed appliance with the same code | 09:58 |
+| 4 | the connect mail + bind | **O1 (pre-declared, not counted):** the operator's „Send self-bind link" pressed once — the customer was already waiting when the automatic trigger shipped. Mail arrived at **09:59:56Z** to `tester1@felhom.eu`, subject „Kösd össze a Felhom dobozodat", naming the two things to enter and the 7-day / 5-attempt limits. The bind page took the pairing code + owner passphrase and answered **„Sikeres összekötés."** | 09:59:55 → 10:01:14 |
+
+| 5 | „ready" | the hub served **agent 0.131.0 / golden 0.243.0** (this run's own bake) at 09:01:59Z; the guest came up and the controller announced itself: `controller_started (0.243.0)` at 10:03:30Z. The box's first host-report carrying a guest: 10:17:16Z (1 guest, 2 storage targets, 1 backup) | 10:01–10:17 |
+| 6 | **the tunnel from outside** (R-510) | three GETs from DooPlex to `https://felhom.enkicsifelhom.hu` → **302 ×3 (cloudflare)**, following → **200** on „A szerver beállítása" — no 502, no 530. **R-510 CLOSED** | 10:04:19–25 |
+| 6b | claim | the setup-code mail („Új beállító kód — újratelepült a szervered", 10:01:57Z, 72 h) + a new dashboard password → **302 → /**. First try refused with „Érvénytelen űrlap": the field names are `code` / `new_password` / `confirm_password` | 10:06:18 |
+| 7 | **the off-site tier** (R-511 → **R-534**) | the WG hook refused exactly as R-511 describes; **O2 pressed** → hub v0.114.0's ADOPT path ran and the ENDPOINT refused: `status 255 … missing Datastore.Modify on /datastore/felhom-offsite` → 502, nothing written (fail-closed). So the adopt fix is sound and **inert until the ep0 grant is fixed** — new row **R-534 (P1)**. The box therefore has **no** whole-guest off-site tier | 10:02:15 / 10:03:29 |
+| 8 | **the file manager** (R-513 on a FRESH box) | the app page shows „Kezdeti belépési adatok — Felhasználónév admin … A jelszót a Felhom állította be ezen a gépen"; reveal → 200, 16 chars; through the tunnel `files.enkicsifelhom.hu`: revealed **200**, `admin`/`admin` **401**, wrong **401** — and admin/admin was already 401 on a probe taken BEFORE any dashboard action | 10:06:43 |
+| 8b | the data drive | „Nincs regisztrált adattároló" on arrival; the wizard formatted and registered `/dev/sdb` as „Adatlemez" (`/mnt/felhom-drives/adatlemez`, default, 97.9 GB) in ~2 s. **Two refusals worth recording:** the mount name rejects accented letters („érvénytelen csatlakoztatási név"), which is the first thing a Hungarian volunteer types, and the API needs `mount_name`, not `label` | 10:20 |
+| 11 | **the backup page** (R-517 on a FRESH box) | per tier: „Helyi tároló (local) ✓ Utolsó sikeres mentés: 2026-09-16 12:08 · 624.3 MB · Naprakész"; „Biztonsági szerver – külön hardver (PBS) **nincs beállítva**"; the remote tile „Távoli rendszermentés **nincs beállítva**" (not ticked); the button says „A mentés alatt az alkalmazások leállnak — általában néhány perc, nagyobb adatnál több." | 10:22 |
+
+| 9 | four apps | deployed through the dashboard API with the new drive as their data path: privatebin and vaultwarden **running by 10:23:29Z**, paperless-ngx and nextcloud **by 10:24:29Z** (2–3 min each); the hub logged four `app_deployed` events. Cards: **no `admin / admin` anywhere**; Vaultwarden's „Első lépések" is invite-first („Users" → „Invite User", „a regisztráció alapból le van zárva"); Paperless points at „Beállítások → Automatikusan generált értékek" and at the file manager's own login page | 10:21–10:24 |
+| 9b | **Vaultwarden, R-512 on a fresh box** | over the public address, a stranger's `send-verification-email` → **400 „Registration not allowed or user already exists"**; the app answers otherwise (its `/api/config` 200) | 10:25:05 |
+| 9c | **Paperless, R-514 on a fresh box** | 20 three-page PDFs posted at once through the public address → **20 SUCCESS, 20 documents**, no OOM; the container carries the new catalog limits (1280M, 1 worker × 1 thread) | 10:25:26–10:27 |
+| 10–11 | **„Mentés most" and the page** | the button's promise measured: privatebin answered 200, went unreachable **10:27:17→10:27:43Z = 26 s**, then answered again while the dump continued — inside „általában néhány perc". The page kept „Helyi tároló (local) ✓ … 624.3 MB · Naprakész" and „PBS — nincs beállítva" throughout, and showed „Mentés folyamatban… (fázis: snapshotted)" while running. **The box's own first scheduled backup had already proven R-518 live**: `backup_tier_skipped (warning)` at 12:08:25 CEST — „tier felhom-pbs skipped: its storage does not exist … No app was stopped for it" + operator mail | 10:27 |
+| 12 | which golden it landed on | **MEASURED, not inferred:** the day-0 install left the golden archive on the box (`vzdump-lxc-9100-…tar.zst`, 653 997 919 B) whose sha256 is **e2d1843c…c10a** — byte-identical to this drill's own bake; the guest runs controller **0.243.0**, so no self-update was needed | 12:02 |
+
+**New finding on the walk: R-535 (P2)** — 25 minutes after a successful bind AND claim, with apps deploying, the box's console still showed „a doboz készen áll, és a párosításra vár" with the pairing code, and still promised „Ez a képernyő magától frissül".
+
+
+## Phase 2 — the faults
+
+Five faults, each recorded the same way: what the customer saw · what the box did · time to steady ·
+did an alarm fire and was it true · did an alarm that should have fired stay silent. Evidence per
+fault in `evidence-drill-0243-2026-09-16/phase2-*.txt`.
+
+| fault | customer saw | box did | steady | alarm |
+|---|---|---|---|---|
+| **F9'** — controller killed 5 s into a deploy, empty budget | dashboard gone ~37 s; the interrupted app simply not installed | agent saw it on sweep 1, confirmed and restarted on sweep 2 (12:31:45 → 12:32:15/16 CEST) | **37 s** | `controller_restarted_by_agent` — true. **But** `app_deployed` for Mealie had already been sent at accept time → **R-536** |
+| **F9''** — three more kills, 20 min apart, at idle | dashboard gone 30–90 s each time; the apps themselves never stopped | restarted every time: **61 s / 41 s / 61 s** back to 200 | 61/41/61 s | none — and that is the finding: the restarts NEVER accumulated (window 15 min), so the 30-minute brake was never armed. A controller dying every 20 minutes is restarted forever, traced only by an `info` event that mails nobody → **R-531**, an operator ruling, measured not changed |
+| **F10** — a child deletes the photo folder | folder and 5 photos gone; after the restore the folder is **back and lists all five**, and **none opens** (`Sabre\DAV\Exception\NotFound`) | tier-1 restore replayed 3 volumes + the database in **35 s** and reported plain success | 35 s | none fired, and **none exists** for "restored database points at files that are not there" → **R-537, R-538** |
+| **F11** — forgotten passwords ×5 | Nextcloud: 401 five times, no lock-out, correct password still works. The box's setup code: wrong twice, then **"Túl sok próbálkozás — próbáld újra 15 perc múlva"** from the third try; "Új beállító kód kérése" still works | claim counter locks the page for 15 min | immediate | `claim_lockout` (warning) at 13:11:42 CEST, operator mail **1 s later** — fired and **true** |
+| **F12** — two reboots inside two minutes | dashboard gone ~2 min, then everything back | boot reconciler restarted all seven stacks; no double start; nothing stuck "telepítés folyamatban" | **124 s** after the second reset | none fired; correct — a reboot inside the liveness window is not an alarm |
+| **M1** — memory pressure (R-528) | app restarted 9–10 times | all three OOM signals **silent**: `OOMKilled=false`, `docker events oom` empty, the cgroup invisible inside the guest, `dmesg` unreadable | — | no OOM alarm is possible on this box, same as on scratch 9202 |
+
+**F10 is the finding of this drill.** On a one-drive box with no off-site tier — the state every fresh
+install starts in — the household's own files are in **no backup at all**: the whole-guest tiers exclude
+the data drive by design (`07-backup-architecture.md`, "[FACT] What the whole-guest tiers do NOT carry",
+confirmed live: `excluding bind mount point mp8 … (not a volume)`), and the app's file leg lives at
+tier 2 / tier 3, both unset. The design is not the defect. The defects are that the page calls tier 1
+„DB + Konfig + Adatok" and prints the drive size beside it (**R-537**), and that a restore reports
+success while leaving the app listing files it cannot open — and wipes the app's own trash, which still
+held every byte (**R-538**).
+
+## Phase 3 — the morning after
+
+**Every app healthy, labels true.** Front doors at 11:15Z: PrivateBin 200, Vaultwarden 200, Paperless
+302 (its login redirect), Nextcloud `status.php` 200, file manager 200 at `files.enkicsifelhom.hu`.
+All seven stacks read `running`. Controller **0.243.0** on the page, agent **0.131.0** on the hub, the
+customer row reads Version 0.243.0 / Floor v0.242.0 — a floor is a minimum, so that is correct, and the
+box runs the golden this drill baked.
+
+**Off-site restore onto 9202 — NOT WALKED, and not for time.** There is nothing to restore from. The
+off-site tier was never provisioned on this box: the re-issue fails on the endpoint token's missing
+`Datastore.Modify` grant (**R-534**), so no descriptor and no upload path were ever created. Read-only
+listing of ep0 confirms it: `ns/tester-1/ct` is **empty** both before (09:12Z) and after (11:14Z) the
+drill, while the neighbouring `ns/demo-hp/ct` lists group 9201 — the positive control proving the
+listing method shows groups when they exist. **Nothing on ep0 was written, removed or pruned by this
+session.**
+
+## Interventions — counted, with the reason for each verdict
+
+**Pre-declared and counted apart:** **O1** the operator's „Send self-bind link" press (the customer was
+already waiting when the automatic trigger shipped) and **O2** the „Re-issue PBS credentials" press.
+
+**Counted interventions: 0.** Nothing on this walk needed a shell, an operator, or knowledge a household
+does not have. The four moments that could be mistaken for one, and why each is not:
+
+| moment | why it is not an intervention |
+|---|---|
+| the automatic reboot re-entered the installer | a volunteer removes the USB stick and powers the box off and on — the same act. It is a real trap and is recorded as one, not as help from outside |
+| the text-mode installer entry was used | the graphical entry IS keyboard-drivable; the walk switched because *I* cannot see the screen without a screenshot. A volunteer looking at a monitor has no such problem. A deviation of method, declared |
+| the claim form and the drive form each refused once | both refusals were **mine**: I drove the API and guessed field names (`code`/`new_password`/`confirm_password`, and `mount_name` not `label`). A volunteer uses the browser form and never meets them |
+| Paperless had to be repaired mid-drill | **my own damage** — I re-ran `docker compose up -d` by hand during the memory measurement and lost the controller-injected environment. Repaired through the controller's own API. Not a product fault |
+
+**What a volunteer WOULD have hit, as defects rather than interventions:** the console keeps showing the
+pairing banner long after the box is bound and claimed (**R-535**), the drive wizard rejects an accented
+mount name — the first thing a Hungarian types (recorded on the walk), and the backup story in Phase 2
+(**R-537**, **R-538**).
+
+## Teardown — three layers, stated
+
+**Evidence first (R-320).** The agent journal (2000 lines), the controller log (91 lines) and the box's
+own state (`pct config`, `qm list`, `pvesm status`, `docker ps`) were copied to DooPlex **before** anything
+was destroyed. Token-leak control: 0 hits in all three files.
+
+**Layer 1 — the machine.** Nested VM **334** (`tester1-drill-0243`) stopped and destroyed with
+`--purge --destroy-unreferenced-disks 1`. After: `qm list` empty, `/mnt/hdd_1/images/334` absent, no file
+matching `*334*` left on the drive. **Fence check: demo-hp's own containers 9201 and 9202 are both still
+running and were not touched.**
+
+**Layer 2 — the host.** Nothing to remove: the drill box WAS the nested VM. demo-hp keeps its standing apps
+and `bentopdf`.
+
+**Layer 3 — the hub.** The **host record** `tester-1-652049` is deleted; the **customer** `tester-1` stays,
+with its e-mail, domain and tunnel. **`RESET` was never used** — the customer-delete form on the hub is the
+one that resets everything, and it was deliberately not touched. The host delete is **refused while a host
+is ONLINE** (409, with no override by design, because a live agent would be permanently 401'd), so the
+record had to fall stale first — which it does only after the machine is really gone. That wait is part of
+the proof, not an obstacle.

+# DRILL — R-102 / R-103: the second drive's copy becomes a way back
+
+**demo-hp (192.168.0.104), guest 9201 · controller v0.229.0 · 2026-08-31**
+
+App under drill: **docmost** — a class-B app (its data is entirely in Docker named volumes and a
+Postgres database; its Tier-2 copy holds a `recovery-unit/` and **no file leg** — confirmed live by
+the Tier-2 run's own line: `Tier 2 copied docmost → …/backups/secondary/docmost (114.5 MB, 0 leg(s))`).
+
+Venue is correct per `runbooks/target-selection.md`: demo-hp is **Tier 0 — disposable**. `demo-felhom`
+was excluded deliberately (it holds the R-313 set-aside fixture and the live Tier-2 copies cited in
+R-102's own evidence); `ep0`, DooPlex and Peti's box were untouched.
+
+Method: **endpoint level** — `claude-in-chrome` is not available on DooPlex, so every action below was
+invoked through the exact HTTP route the UI's button posts to, with a real session cookie and a real
+session CSRF token. No server logic was skipped; only rendering was.
+
+## What was proven
+
+| # | Claim | Where |
+|---|---|---|
+| 1 | The mirror on the second drive is a complete package (manifest schema 2, compose incl. app.yaml, 3 volume tars, 1 canonical `.sql`) | `phase0-1-…log` |
+| 2 | After a capture + Tier-2 run, primary and mirror are **byte-identical** (4/4 sha256) | `phase2b-3-5-…log` |
+| 3 | The app's live data can be destroyed and the loss proven **through the observable** — the accented file gone, and the app's own database answering `relation "felhom_r102_discriminator" does not exist` | `phase4-destroy.log` |
+| 4 | With the **primary unit moved aside**, `POST /backup/tier2/unit-restore` restores the app from the mirror in **28.65 s** — `Restoring docmost from recovery unit /mnt/felhom-drives/hdd_1/backups/secondary/docmost/recovery-unit`, 3 volumes of 3 listed, 1 database of 1 listed | `phase6-…log` |
+| 5 | The data came back **byte-for-byte**: accented filename `Árvíztűrő tükörfúrógép.txt` verified as **hex** `c3817276c3ad7a74c5b172c5912074c3bc6bc3b67266c3ba72c3b367c3a9702e747874` (35 bytes) and content sha256 `9228fdda…c444`; the app read its own row **over TCP with its own credential** (`docmost@172.20.0.2:5432`); docmost answered HTTP 200 | `phase7-…log` |
+| 6 | The restore is a **real replay, not a no-op**: the post-backup discriminator (`csak-mentes-utan.txt` and the `post-backup` row) was **GONE** afterwards | `phase7-…log` |
+| 7 | **Scenario D** — with the guest's `app.yaml` moved aside, the restore still succeeds: `secrets recovered=2/2` **from the mirrored unit**, the guest's `app.yaml` rebuilt from it at 0600, the app reading its own rows with its own credential. This closes `00-capability-map.md`'s open clause *"Tier-2's own cross-drive copy of a secret-bearing unit … not exercised live"* | `phase8-…log` |
+| 8 | **R-103 live** — the file restore's refusal now names the action beside it, not a button on another page (302 carrying `tier2UnitAvailableMsg`) | `phase9-…log` §9b |
+| 9 | The ordinary primary restore still works: 3 volumes of 3, 1 database of 1, from `…/backups/primary/docmost` | `phase10-…log` |
+
+## What went wrong during the drill, and what it exposed
+
+**Phase 4, first attempt, destroyed nothing.** `docker volume rm` was refused because the stopped
+containers still referenced the volumes; the command printed nothing and the loop's `&& echo` never
+fired. Re-run as an in-place wipe with `du -sb` before and after as the positive observable
+(`phase4-destroy.log` states this at the top). *An unchecked exit code that looks like success* is the
+trap the workspace's own rule 1 exists for.
+
+**Phase 9a mis-restored the primary unit — and the reason is a real product finding.** Two seconds
+after the phase-6 restore completed, the periodic backup-status refresh
+(`backup.go:1116 → captureAllRecoveryUnits`, the 5-minute `backup-cache` job) rewrote
+`backups/primary/docmost/` from a drive whose dumps were not there, producing a **hollow unit**:
+`manifest.json` with `"db_dumps": []` and `"volume_dumps": null`
+(`evidence-hollow-primary-manifest-1002.json`, `created_at 2026-08-31T10:02:59Z`). The ordinary
+restore then read it and reported, correctly and uselessly, *„ez a mentés csak a beállításokat
+tartalmazta, adatot nem."* Repaired in `phase10-…log`; the app was left healthy with its data back.
+
+**This is filed as R-403 and is NOT fixed here.** The dangerous half is stated as unverified: `RunTier2`
+mirrors the primary unit with `rsyncMirror`, which carries `--delete`, so the next nightly run would
+mirror a hollow unit over the good secondary copy. Nothing in `f5_stale_primary_test.go` or the R-181
+capture floor guards that direction. **It was not tested live and must not be reported as measured.**
+
+## Teardown — all three layers
+
+- **Machines provisioned:** none. The drill used the existing guest 9201; no VM, no scratch guest.
+- **Hub records created:** none. No enrolment, no appliance, no escrow.
+- **On-box artefacts:** the driver script, the password file, the session file and the phase scripts
+  were shredded/removed; the hollow-unit copy was pulled off as evidence and then deleted. The
+  controller's `settings.json.r102bak` was removed.
+- **The drilled app:** docmost is **running and healthy, with its data back** (`HTTP 200`, 3 volumes and
+  1 database replayed from its primary unit). Primary and secondary are byte-identical again on all
+  five artefacts. The drill's own planted rows (`felhom_r102_discriminator`) and the accented file
+  remain in the app, exactly as the earlier `felhom_r356b_discriminator` drill left its own.
+- **An operator-visible mistake I made, and its repair — stated because the box was changed.** I read
+  `POST /login` returning 200-with-the-login-page as *"the shared demo password has drifted again"* and
+  re-set `password_hash` in `data/settings.json` to `bcrypt(PASSWORD)`. **The password had not
+  drifted.** Values in `~/.config/credentials` are **single-quoted**; my extraction stripped only `"`,
+  so I was sending a 15-character string where the password is 13 — the exact misdiagnosis the memory
+  `credentials-file-values-are-quoted` records, and which the v0.228.0 report had recorded on this same
+  box on this same day. **This is the third instance.**
+
+  Repaired: `password_hash` was re-set to `bcrypt(<correctly unquoted PASSWORD>)` and login verified
+  (302 + `felhom_session`). The box's end state therefore matches the state the v0.228.0 session
+  independently verified. **What cannot be claimed:** that the ORIGINAL hash bytes were restored — I
+  deleted my own `settings.json.r102bak` before finding the error, so the original is gone. The
+  end state is correct by verification, not by restoration. Filed as an Observation in
+  `felhom-controller/REPORT.md`.

+# DRILL — R-329 + R-386: the alarm that fired but reached nobody, and the stop nobody heard (2026-08-23)
+
+**Controller v0.222.0 → v0.223.0. Hub v0.106.0 → v0.107.0. Live leg on `demo-hp` (Tier 0), guest
+9201. UNATTENDED.** Method: endpoint-level plus the hub's own SQLite records — no browser exists on
+DooPlex. Guest and hub clocks are UTC; the hub pod logs CEST.
+
+## Verdict
+
+| Part | Outcome |
+|---|---|
+| 1.1 the severity word + sweep | ✅ **exactly one** bad severity in the whole controller |
+| 1.2 the AST contract guard | ✅ and it found two dynamic sites the hand sweep missed |
+| 1.3 customer toggle, default OFF | ✅ |
+| 2 the hub says what it rewrote | ✅ hub v0.107.0, proven live |
+| 3 ask the field that knows | ✅ proven live, both directions |
+| 4 split the compound toggles | ✅ round trip byte-identical |
+| 5 record the notification philosophy | ✅ recorded, **not implemented** |
+
+**No halt condition fired.**
+
+## The one number that says it all
+
+Read from the live hub DB:
+
+```
+91 app_start_failed events stored, all-time
+ 0 notification_log rows before 2026-08-23 09:00   <- not one, ever, on any channel
+```
+
+After the fix, at 09:27:51: **one row — `warning` / `sent` / `operator`.**
+
+## The two live pairs
+
+**Scenario A** — a database dies, customer has not opted in:
+
+```
+events         : demo-hp  app_start_failed  warning  2026-08-23 09:27:51   <- v0.223.0
+                 demo-hp  app_start_failed  info     2026-08-23 05:30:14   <- v0.222.0, coerced
+notification_log: demo-hp  app_start_failed  warning  sent  operator  09:27:51
+                 (no customer row)
+```
+
+**Scenario D** — an app stopped out of band, intent `running`:
+
+```
+2026/08/23 05:47:44  [deadapp] check alive: 40 scans since boot, 8 deployed app(s) evaluated, 0 currently down   <- v0.222.0
+2026/08/23 09:34:51  [deadapp] check alive: 20 scans since boot, 8 deployed app(s) evaluated, 1 currently down   <- v0.223.0
+```
+
+Alarm fired **24 seconds** after the `docker compose stop`.
+
+## Three things that had to be re-run, and why that matters
+
+1. **Red-proof 5 passed first time — the mutation was INERT.** Changing `if next <= prev` to
+   `if next < prev` in fillwatch does nothing, because an earlier `if next == prev { continue }` had
+   already removed the equal case. The test was right to pass. Removing the guard outright convicts
+   it. **Check the mutation applied before believing either verdict.**
+2. **Scenario G was silently refused TWICE behind an HTTP 200.** The empty-email wipe guard declines
+   the save and renders an error page — still `200`. The first run had no prefs at all; the second
+   read the email with a single-line grep from a `<input>` that spans **three lines**, got `""`, and
+   was refused again. Both times the before/after hashes matched — *because nothing was saved*, not
+   because nothing changed. Fixed by asserting the refusal banner is **absent**. **A warning beside a
+   success is read as a success.**
+3. **The live Scenario A does NOT prove the customer gate**, and is not claimed to. `demo-hp` has no
+   `customer_notifications` row at all, so the customer leg could not have delivered regardless. The
+   toggle gate is proven by the unit tests, which configure prefs both ways. Stated rather than
+   implied.
+
+## Evidence index (`evidence/`)
+
+| File | What it shows |
+|---|---|
+| `redproof-1-R329-emitter.txt` | severity back to `"warn"` → AST guard names file, line and value |
+| `redproof-2-R386-intent.txt` | intent test reverted → `dead-app banner = []`, the live symptom |
+| `redproof-3-part4-migration.txt` | no-op-save guard removed → the `defaults` case reorders |
+| `redproof-4-R387-ingest.txt` | hub WARN removed → "the hub rewrote a severity and said nothing" |
+| `redproof-5-fillwatch-consequence.txt` | the inert first attempt, and the effective one |
+| `live-01`…`live-04` | Scenario A: stop, controller send, **hub records**, customer-leg control |
+| `live-05-step4-absent-intent-count.txt` | **0 of 8** deployed apps carry an absent intent |
+| `live-07`…`live-09` | Scenario D: out-of-band stop, alarm in 24 s, the heartbeat pair |
+| `live-10`, `live-11` | Scenario C: UI Stop → intent `running`→`stopped`, 0 alarms / 9 scans |
+| `live-12`, `live-13` | Scenario E: intent removed → suppressed **and** the log line names the app |
+| `live-16-scenarioG-roundtrip.txt` | all three attempts, ending byte-identical (`10840f3a…`) |
+| `live-18-golden-bake.txt` | golden 0.223.0 markers, each counted |
+| `live-19-scenarioH-after.txt` | the new hub WARN line, live, with a silent `error` control |
+| `live-06`, `live-14` | full controller-log windows (1041 and 4044 lines), pulled before each revert |
+
+## Observations — noticed, recorded, NOT acted on
+
+1. **The operator cooldown has no app identifier, and it now bites.** PrivateBin's event 4 minutes
+   after BookStack's was logged `suppressed — operator cooldown 1h, key=demo-hp:app_start_failed`. So
+   **only the first app-down per hour e-mails the operator.** This is R-182's known cooldown-key
+   shape; it was harmless while the event was undeliverable and is not any more. Recorded, not fixed.
+2. **The prompt's §6 premise was wrong and is corrected:** the hub's manifest **is** in version
+   control, at `felhom.eu/manifests/hub.yaml:128`, and ArgoCD app `felhom` tracks
+   `admin/felhom.eu.git` path `manifests`. No out-of-git deployment path exists.
+3. **The golden-bake runbook still lacks `pveam update`** — second bake in a row to hit the stale
+   index on the `virgin` snapshot, presenting as `400 … no such template`.
+4. `internal/notify/notifier.go` carries **pre-existing** gofmt drift in a const block, confirmed by
+   stashing this session's work. Not touched (§12).
+
+## Teardown
+
+Nothing provisioned. Every app restarted and confirmed healthy (17 containers). `privatebin`'s
+`app.yaml` restored from its backup and the backup removed; its intent reads `running` again.
+`demo-hp`'s notification settings restored to `enabled_events: null`, no e-mail — the state they were
+in before the drill. The drill VM is powered off, its Gitea token shredded, and `drill.qcow2` reverted
+to `virgin`. **Hub-side: two probe events (`backup_failed`, "R-387 scenario H probe"/"control") were
+POSTed to the live hub for Scenario H and remain as event rows for customer `demo-hp`.** They are
+inert records; named here rather than left for someone to find.
