+## Unreleased — „Reboot guest" from the hub (D65 = A): `reboot_guest` joins the agent's closed list
+
+- **D65 = A (operator ruling 2026-10-29 15:50; felhom.eu `04` §6.1, `03`).** The agent's closed operator-action list is
+  now `restart_controller` and `reboot_guest` (arg: the vmid). No signature: a reboot destroys nothing. The act is the
+  existing guest-reboot path (`pct reboot <vmid>` of THAT guest over the existing exact grant) — never the host.
+- **Guards** (each refuses with the reason; nothing is called, no record is written): a guest this agent did not
+  provision, not running, locked, or parked; the host-wide heavy-operation gate held (a backup of any tier the agent
+  runs, a restore test, an OS step — the reboot HOLDS the gate until the guest is up again); `jobBlocker` (an agent
+  backup job, a controller swap, a drive or NAS job, an escrow ceremony, a vzdump of the guest); the CONTROLLER busy —
+  its `data/ctl/busy` file (a backup, a restore, an off-site run, an app update), fresh within 90 s; a stale file is a
+  controller that stopped writing, not a busy one; any read failure but „no such file" refuses (fail closed); at most
+  ONE reboot per hour per guest (`<guests>/<vmid>/operator-reboot.json`, on disk — it survives an agent restart); the
+  operator restart's brake (a refusal in force refuses a reboot; a reboot counts as one of the 3 restarts in 15 minutes).
+- **During the reboot** the guest-power watchdog and the controller supervisor leave the guest alone (`rebootInFlight`):
+  a racing start would fail the reboot's own start half.
+- **The result** says both times from the press: „rebooted; the guest was up after 41 s, the controller answered after
+  63 s" — or `failed`, said plainly. The record is written BEFORE the reboot; the new self-scoped
+  `GET /guest/operator-reboot` gives it to the controller for one day, for the household's line „Felhom support
+  restarted your box at <time>".
+- **One new sudo vector** (configs/ changed → the signed config bundle): `pct exec <vmid> -- cat
+  /var/lib/docker/volumes/felhom-controller-data/_data/data/ctl/busy` — read-only, one fixed path, in
+  `FELHOM_CONTROLLERSWAP`; capability `controller-busy-read` (not critical: without it, every reboot press is refused).
+- Tests `TestOpReboot_*` (the times + the record + the gate given back; 13 guard cases; a stale busy file; once per hour
+  across an agent restart; the brake counting a reboot; a failed reboot; the watchdogs leaving the guest alone; the
+  notice expiring after a day) and `TestOpActions_AgentClosedList` — each seen failing by a mutation (19 mutants).

+## v0.169.0 (2026-10-29) — „Restart controller" from the hub (the agent's own closed list); the unresponsive controller ALARM (R-1344) — RELEASED (release-agent.sh from a clean clone of `637c92c`; agent sha256 fc066de640007038ecfaed6a23e4301a27fc486f1d7851c36177acdd26c2df61, bundle 3ca33f9cbab3bdd4c1b7f8ac90aa21e43b64209f1cb45c77ac72b3405956041b; binary-only signed updates committed on demo-felhom, Tester 1, demo-hp) — **VOUCHED by the operator 2026-10-29 14:06:09 CET**; Day-0 pin set (D50). Live on Tester 1: four presses (one with the controller stopped, the fourth refused by the brake)
+
+- **Operator actions for the agent (operator brief 2026-10-29, Part 1; felhom.eu `04` §6.1).** The host-report reply may
+  carry `operator_actions: [{id, action, arg}]` (`hub.ControlEnvelope.OperatorActions`); the agent acts ONCE per id and
+  answers on the next report, `operator_action_results: [{id, outcome, message}]` (`hub.HostReport`), which it requests
+  at once through the cap-1 report trigger. CLOSED list: `restart_controller <vmid>` only — anything else refused, nothing
+  called. The act is the supervisor's (`systemctl restart felhom-controller-bootstrap.service` in the guest, existing
+  grants — no sudoers change, no config bundle) with its guards: provisioned guest, guest running, the guest list and the
+  vzdump state readable, not parked, no swap, not locked, no vzdump. The thrash brake counts operator restarts with the
+  supervisor's: 3 in 15 minutes → the press is refused, and presses stay refused for 30 minutes. The result says how long
+  the controller took to answer (Docker's health check: healthy), or `failed` when it did not within 3 minutes. One
+  `audit: operator action` line per decision. Works with the controller stopped. Tests `TestOpActions_*` (closed list,
+  unknown/bad arg refused, restart + answer time + report trigger + once per id + re-send until dropped, stopped
+  controller, every guard, the brake across supervisor and operator restarts, no healthy answer = failed) and
+  `TestMainWiresTheAgentOperatorActions` (AST) — each seen failing by a mutation.
+- **R-1344 — a controller that RUNS but does not answer: ALARM ONLY.** Each sweep also reads Docker's health status for a
+  running controller (the swap's `docker inspect -f` grant); 6 consecutive „unhealthy" sweeps (3 minutes, on top of
+  Docker's own ~90 s) start an episode: one ERROR line, the stanza's `unresponsive` / `unresponsive_since` (the hub raises
+  `controller_unresponsive`, operator-only). NOT restarted for it: the brief allows the restart only after a measurement
+  shows a busy night never reads like this, and that measurement runs through tonight (felhom.eu R-1344). Not counted
+  during a swap, a parked or locked guest, or a vzdump; healthy / starting / no health check / an unreadable status reset
+  the count. Tests `TestSupervisor_Unresponsive*` (red by mutation: the vzdump guard, the threshold).
+
+## v0.168.0 (2026-10-29) — R-528: the host's per-container OOM counter (`GET /guest/oom-kills`); R-1254: a lost or late escrow answer is asked again before it is worded — RELEASED (release-agent.sh from a clean clone of `91bd96c`; agent sha256 1e70196c51346cf10e3f04f51975de5899b5dc6baa5a45ec1d17bc248830d2ca, bundle 3415c034955d46c59ca3f7b284a648abf852b1257b77cc49bd6ea9994a7b8cb8; no configs/ change since v0.167.0 → binary-only signed updates to demo-felhom, Tester 1, demo-hp) — **VOUCHED by the operator 2026-10-29 10:21:56 CET**; Day-0 pin set (D50)
+
+### R-528
+
+- **Why:** inside a Felhom LXC guest Docker can leave `State.OOMKilled` false and send no `oom` event after a
+  memory-limit kill (measured 2026-09-15 on 9202 and 2026-09-16 on a fresh install), so the controller's OOM line
+  could not fire. The kernel counts every kill per container cgroup, and the host can read it.
+- **`internal/localapi/guest_oom.go`:** `GET /guest/oom-kills` (withGuest — the token's guest only; a cross-guest
+  `?vmid=` is 403) reads `/sys/fs/cgroup/lxc/<vmid>/ns/system.slice/docker-<64-hex>.scope/memory.events` (and
+  `ns/docker/<id>/` for the cgroupfs driver), line `oom_kill N`, and answers `{vmid, available, containers: {id: n}}`.
+  A guest with no cgroup folder → `available: false`. Read-only, no sudo: the files are 0444 and the non-root
+  felhom-agent user reads them (measured on Tester 1's host 2026-10-28). A container's scope is new at each start, so the
+  count is per container run. Tests `TestR528_*` (a fake cgroup tree; red-proved: a glob over every guest leaks another
+  guest's container; parsing `oom` instead of `oom_kill` reads the wrong number).
+
+### R-1254 (the ceremony half, review round 2 HUNT-3 H2)
+
+- **The defect:** the claim's (R-978) and the confirm's (R-1151) package upload can lose its answer, or answer late
+  (30 s), AFTER the hub stored the new package. The agent then answered 502 „the previous code still works" — false: the
+  hub's current package opens only with the NEW code.
+- **Now (`internal/localapi/escrow_ceremony.go`):** after a failed upload the agent asks the hub (`HubHolds`, 15 s,
+  outside the lock, the slot still marked claiming): the hub holds THIS package → a success (the code is handed out /
+  the confirm completes; a WARN line names the lost answer); the hub holds another package → 502 and the old sentence,
+  now true; the hub cannot be asked → **504** with a sentence that promises nothing about either code, and the wait goes
+  on (a retry decides). `cmd/felhom-agent`: `HubHolds` compares the pending package's identity blob with the one the hub
+  serves back (`GET /api/v1/hosts/<id>/escrow`, the read-back the agent already uses; ciphertext only, nothing logged);
+  a package without an identity blob cannot be compared → unknown. Tests `TestR1254_*` (localapi, red before the fix:
+  502 while the hub held the new package) and `TestR1254_HubHoldsComparesTheIdentityBlob` (red-proved by mutation).
+- Needs controller ≥ the R-1254 controller commit (2026-10-28 night) to word 504 for the household; an older controller
+  shows its generic „A kód lekérése nem sikerült." (claim) / its 502 sentence (confirm) for it.
+
+## v0.167.0 (2026-10-27) — the BYO SSH clean-up in the SAME update (R-1285); a reinstalled box's whole-guest tier is due at once (R-1232); Go 1.27.3 (R-972) — RELEASED (release-agent.sh from a clean clone; agent sha256 28bdd282…d826f0, bundle 9d034416…ed1268; signed updates committed on demo-felhom, Tester 1, demo-hp; VOUCHED by the operator 2026-10-27, Day-0 pin set)
+
+- **R-972: Go 1.27.3** (`go.mod`; released 2026-10-19 with a security fix to `crypto/x509`). `govulncheck` v1.8.0 before:
+  1 called vulnerability (GO-2026-6809, `crypto/x509@go1.27.2`); after: 0. `golang.org/x/crypto` v0.58.0 is already the
+  newest. Full `go build/vet/test` green. The controller and hub move the same night.
+- **R-1232 (P2):** `backup.BackupRunner.NewestArchiveTime` — the tier due-check — counts only archives written with THIS
+  storage's key on an encrypted storage (the R-727 discriminator; the archive carries no host id). Before: a reinstalled
+  box shares the customer's PBS namespace and guest number with the old box, the old box's archive read as „the last
+  backup", and the whole-guest tier waited up to its 168-h cadence (the 2026-10-23 test night). A key lookup failure is
+  an error (the due-check reads UNKNOWN), never a foreign age. Tests `TestR1232_*` (foreign only → none; own → its time;
+  an unencrypted dir → unfiltered), red-proved (case 1 returned the old box's time).
+
+- **The cause (measured 2026-10-26 on demo-hp, felhom.eu R-1285):** a box gets `agent_update` and `agent_config_update` in
+  one pass; the bundle job runs in the OLD process (no policy pass in it) and the restart into the new agent comes a
+  second later — so 0.166.0's pass never ran on the bundle that delivered it.
+- **The fix:** `selfupdate.Manager.SetOnCommitted` — a hook run once right after „update committed"; `main.go`
+  `wireBundlePolicyAfterCommit` hooks `osupdate.ConfigUpdateExecutor.PolicyPassAfterUpdate` (the wrapper's
+  `bundle-policy` mode, host layer, no envelope) onto it. By the commit the wrapper on disk is the bundle's own, so a BYO
+  host loses our drop-in in the same update. Idempotent; an appliance removes nothing. The smaller of the two fixes:
+  agent-only — holding the bundle job until the commit would need new hub queue logic.
+- **Test in the real order:** `cmd/felhom-agent/r1285_policy_after_commit_test.go` — a pending marker for the running
+  version → commit, THEN one `bundle-policy` plan; no marker / a mismatched marker → nothing. Red-proved (the hook call
+  removed → commit only, no pass — the demo-hp symptom).
+- **Which box can show it live:** only one coming FROM 0.164.0 — 0.165.0's wrapper already applies D43 at plan time, so a
+  0.165.0 box passes even without this fix.
+
+## v0.166.0 (2026-10-26) — a signed job's window is at most 24 h (R-1280); the policy pass after each bundle (R-1285); the published gate follows D50 (R-1290) — released in the attended release run; **VOUCHED by the operator 2026-10-26 10:04:55 CET** (binary `3f22c65b…`, bundle `093772c1…`)
+
+Released from a clean clone at `aa69114` (tag `v0.166.0`; binary sha256 `3f22c65b78914632fa476292f6b58e5af3ed9e9900f3a5a7a347a9c0bfea9c5c`,

+by signed `agent_update` + `agent_config_update` (each: COMPLETED, bundle INSTALLED, self-check 76/76, update committed).
+Live: a 25 h signed job REJECTED on demo-hp („op validity window too long"), a 30 min one ran; `felhom-opsign -ttl 25h`
+refuses. D50 pin `day0_agent` → 0.166.0 (`scripts/retention-policy.json`). Evidence: felhom.eu
+`documentation/audits/release-monday-2026-10-26/agent-0166/`.
+
+**Found at the release (felhom.eu R-1285, back to OPEN):** in the normal two-job delivery the bundle job runs in the OLD
+process (0.165.0) before the restart into 0.166.0, so the policy pass does not run on that bundle — a BYO host coming
+from 0.164.0 still loses our drop-in one release late. The pass itself is wired: under 0.166.0 a later bundle logged
+„BUNDLE POLICY DONE install_mode=appliance removed=0".
+
+### 2026-10-25 (night, unattended) — a BYO host loses our SSH drop-in in ONE update (R-1285) — committed, NOT released
+
+- **The cause, measured 2026-10-25 on a BYO test host:** the bundle that brings a new `felhom-os-apply` is planned by
+  the OLD one on disk, which did not know D43's appliance-only policy — so a BYO host upgraded from 0.164.0 kept our
+  drop-in until its next bundle. A change inside the wrapper alone cannot fix the run that delivers it.
+- **The fix — the new AGENT asks the new wrapper:** `internal/osupdate/bundle.go` runs a policy pass right after every
+  bundle install (`mode: "bundle-policy"`, host layer, no envelope); the wrapper on disk is the bundle's own by then.
+  `configs/felhom-os-apply` `Bundle.policy_pass`: on a root-owned BYO record it removes the appliance-only files WE
+  wrote (our header), keeps the previous copy beside the bundle's, `sshd -t` then reloads ssh — a failing `sshd -t` puts
+  the file back. It writes nothing, so it needs no signature; an appliance and the owner's own file are left alone. Never
+  fatal for the agent: an older wrapper refuses the unknown mode and the next bundle does it. Report key `bundle_policy`.
+- Tests: `TestR1285_AnInstalledBundleIsFollowedByThePolicyPass` (a refused bundle runs no pass);

+### 2026-10-25 (night, unattended) — a signed job's window is at most 24 h (R-1280, D44 #22) — committed, NOT released (rides the next agent release; the vouch is the operator's)
+
+- `internal/authz/verifier.go`: `MaxWindow = 24h`; a blob whose `expires_at - issued_at` is longer is refused
+  (`ErrWindowTooLong`) before the expiry and nonce checks — a job signed with a long window by mistake no longer stays
+  usable that long, and the nonce store no longer keeps its record that long.
+- `configs/felhom-os-apply`: the root wrapper holds the same 24 h (`MAX_WINDOW_S`, refusal R3 „the signed job's window
+  is longer than 24 h").
+- `cmd/felhom-opsign`: `-ttl` above 24 h (or ≤ 0) is refused before anything is signed.
+- Tests: `TestVerify_RejectsPerStage/window_longer_than_24_h` and `…/window_of_exactly_24_h_is_accepted`;

+
+### 2026-10-25 (evening, attended) — the `published` gate follows D50 = A: the newest 5 plus the pinned MinAgent and day-0 agent (R-1290; no binary change)
+
+- **D50 = A** (operator, 2026-10-25): the registry keeps the newest 5 released agent versions, the hub's MinAgent floor and
+  the day-0 manifest's agent. `scripts/retention-policy.json`: `generic_versions_kept` 10 → 5, new `pinned`
+  (`hub_min_agent` 0.158.1, `day0_agent` 0.165.0 — copies of hub state, because CI holds no hub secret; the session that
+  records a vouch or a new MinAgent updates them in the same commit). `check-published-versions.py` asserts the window
+  plus every pin; a pin with no tag FAILS. CI was red since the operator's hand prune of 0.159.0–0.160.0 (job 2334).
+- **Decoys** (`test_gate_decoys.py`, via `FELHOM_RETENTION_POLICY`, test only): a pinned version older than the window is
+  asserted; its 404 convicts; a pin with no tag convicts. Seen failing on the old gate (two LIVE HOLES): felhom.eu
+  `documentation/audits/night-2026-10-25/redproof-d50.txt`.
+
+## v0.165.0 (2026-10-25) — D43 = A: BYO hosts keep their own SSH settings (R-1257); the line test for a box that seeds all day (R-1250) — released in the attended release run; **VOUCHED by the operator 2026-10-25 18:38:49 CET** (binary `e9d04a47…`, bundle `8dea1f34…`)
+
+**Found at the release (felhom.eu R-1285, P4):** on a BYO host upgraded from 0.164.0 the drop-in is removed only on the bundle run AFTER the one that installs this wrapper — the first run is planned by the old wrapper. Proven on a BYO test host (VM 9371 on demo-hp): the second `agent_config_update` logged `BUNDLE REMOVED … (ours, on a BYO host — D43)`.
+
+### BYO hosts keep their own SSH settings (R-1257, D43 = A) — 2026-10-24 night
+
+- **The root-key-only sshd drop-in (`/etc/ssh/sshd_config.d/10-felhom-root-key-only.conf`, R-982 / D4) goes only to an
+  appliance** — operator ruling D43 = A (2026-10-24): a BYO host belongs to its owner (`11` §1). The table entry's policy
+  is now `appliance`: written only when the ROOT-OWNED install record (`/var/lib/felhom-install/state.json`) says
+  `appliance`. On a `byo` record nothing is written, and a copy WE wrote (this exact path, beginning with our header
+  line) is REMOVED, its previous copy kept for the undo, then `sshd -t` and a reload. A box whose record is absent or
+  agent-writable proves nothing and is left exactly as it is. The bundle report lists `removed`; the record says
+  `removed` / `skipped`. The installer records the mode before it installs the bundle, so a new appliance still gets it.
+- **X3: the „in force" check asks sshd about each of the host's own LAN addresses** (`ip -4 -o addr show scope
+  global`), not only 192.0.2.1 — a `Match Address <LAN>` block that re-allows root passwords no longer reads as in force.
+- **X4: a failing `sshd -t` puts back ONLY the SSH step** (`undo_sshd_step`: the previous copy, or none; sshd is not
+  reloaded, so it never ran the refused state) and the rest of the bundle stays; it used to refuse and undo the whole
+  bundle. The report carries `sshd_step_undone`; the record names what is on disk.
+- Tests (`configs/test_felhom_config_bundle.py`, class `ByoKeepsItsSSH`, 7 tests; each rule seen failing with it taken
+  out): a BYO host gets no drop-in; our copy comes off a BYO host; the owner's own file stays; no record → left as it
+  is; a LAN `Match` block is not in force; every address key-only passes; a failing `sshd -t` undoes only the SSH step.
+  The fake box now carries an appliance record by default (every earlier test unchanged).
+
+### The line test for a box that seeds all day (R-1250) — 2026-10-24
+
+Attended brief 2026-10-24, Part 4 (commit only; the release rides the next normal train). The weekly test (v0.164.0)
+starts only after 10 quiet minutes; a torrent app that seeds all day never gives them, so that box never got a tested
+line and qBittorrent never got its 50 % limit. Now:
+
+- **`linetest.Tester.WaitingForQuiet`** — due, inside the window, tries left, tunnel up, and only the quiet missing.
+  `GET /host/line-test` carries it as `waiting_for_quiet`; a controller with a seeding torrent app acts only on it.
+  It needs the full watched window (11 minute samples): a freshly started agent is not known to be busy, so it never
+  invites a hold (found in the live proof, 2026-10-24: the first build said `true` before one minute was watched;
+  `TestFreshTesterIsNotWaiting`).
+- **`linetest.Tester.RunNow`** and **`POST /host/line-test/run`** (synchronous, about 55 s) — a test on request while the
+  controller holds its app's upload low: every weekly rule holds (due, window, `MaxTriesPerDay`, tunnel, the one heavy-op
+  gate) except the 10 quiet minutes, which become a 5 s settle and a 10 s quiet check (below 2 Mbit/s, so a request
+  never measures the family's own upload); the three runs are 5 s apart instead of 30. A refusal answers its code
+  (`not-due`, `outside-window`, `tries-used`, `no-tunnel`, `heavy-op`, `not-quiet`, `server-busy`); a failed request
+  spends one of the day's tries. `Tick` and `RunNow` now share one `ready()` check.
+- Tests (each seen failing): `TestSeedingBoxIsWaitingForQuietAndRunNowMeasuresIt` (the sleeps, the 60 s bound),
+  `TestRunNowRefusesAnUplinkThatIsStillBusy`, `TestRunNowKeepsTheWeeklyRules`, `TestRunNowFailuresSpendTheDaysTries`,
+  `TestQuietBoxIsNotWaiting`, `TestLineTestRunRoute`; a compile-time assertion that the Tester serves the request half.
+
+**No sudoers or config-bundle change. MinController: none** — an older controller never calls the route.
+
+## 2026-10-24 (review round 2, unattended) — `.claude/rules/unprompted-work.md` aligned with its four siblings
+
+- The copy lacked item 6's paragraph „A version number is pushed once …" that the felhom.eu and felhom-controller copies
+  have carried since 2026-10-15; the file's header says „change all five or none". The paragraph states a fact
+  (`felhom-controller/controller/build.sh` refuses an existing tag and an unreachable registry). Now byte-identical to
+  the other four (md5 b1891bd4). No code change. Record: felhom.eu `documentation/audits/review-round-2-2026-10-24/EDITS.md`.
+
+## v0.164.0 — the weekly upload line test (R-1247) (2026-10-24) — RELEASED on the operator's ruling (attended release run); vouched by the operator 09:44:58 CEST
+
+Binary sha256 `1b803d8b70f8afbe1546f6989f35b6b0e29c9ed63f6acb3843d3c04ef0d24b2b`; config bundle sha256

+`f7e1dcb` (CI 2277 green) in a fresh clone by `scripts/release-agent.sh`. Delivered by one signed `agent_update` per box
+(07:25Z): Tester 1, demo-hp and demo-felhom — COMPLETED, self-check 76/76, committed after the 1-minute dwell, the line
+test started (felhom.eu `audits/line-test-2026-10-24/agent-0164-boxes.txt`).
+
+Operator ruling 2026-10-24 07:26: once a week the box's HOST measures its upload line with a 10-second iperf3 upload to an
+iperf3 server on ep0 that answers **only inside the WireGuard tunnel** (felhom.eu `scripts/ep0-iperf3/`; installed the same
+day). The agent speaks the iperf3 protocol itself (operator's pick, 2026-10-24: nothing is installed on any host).
+**No sudoers or config-bundle change.** **MinController: none** — the controller (≥ 0.342.0) reads the new route and
+treats a 404 as „not measured".
+
+- **`internal/linetest`** — `Client` (the iperf3 3.x client protocol: cookie, params, N data streams, TEST_END, results
+  exchange; the value is the SERVER's received bytes) and `Tester` (the schedule): due weekly from Tuesday 10:00 local,
+  starts 10:00–15:59 only (never in the night chain), from a per-host slot spread over 10:00–13:59; only after 10 quiet
+  minutes (every one-minute transmit rate of the host's physical uplink below 2 Mbit/s); under the one-heavy-op gate
+  (`line-test`); 3 runs of 10 s with 4 streams, 30 s apart, the highest counts; each run bounded by 25 s; „server busy" →
+  tried again at the next tick the same day, at most 6 tries a day; no operational tunnel → no test, no value. The last
+  result is persisted (`<oob state dir>/line-test.json`).
+- **Report:** a `line_test` stanza (`schedule`, `last_ok_at`, `mbps`, `runs_mbps`, `server`, `last_attempt_at`,
+  `last_error`). **Local API:** `GET /host/line-test` → `{present, mbps, measured_at, method:"iperf3-tunnel"}`.
+- `wgtunnel.Manager.LineTestTarget()` — the desired block's `pbs_tunnel_ip`, only while the tunnel is operational
+  (cached, no exec). Config `line_test.disable` (default on).
+- **Proven live** (felhom.eu `audits/line-test-2026-10-24/`): a probe built from this package on demo-hp's host read
+  **90.7 Mbit/s** in 10.4 s (the push floor said „at least 10"); a second test 2 s later → „server busy" in 0.1 s while the
+  first went on undisturbed (90.6).
+- Tests, each red-proved by a mutation (15): `TestClientSpeaksTheProtocolAndCountsTheServersBytes` (against a fake
+  iperf3 server), `TestClientBusyServerIsErrBusy`, `TestClientHonoursTheDeadlineAgainstAStalledServer`,
+  `TestEligibleWindowNeverInTheNightChain`, `TestNeverTestsInTheNightOrBeforeTuesday`, `TestBusyServerIsRetriedLaterTheSameDay`,

+## v0.163.0 — the tunnel heals itself after a clock that ran ahead (D30, R-1204); root SSH from the LAN by key only (D4, R-982) (2026-10-23) — RELEASED on the operator's yes (day brief); the vouch is the operator's
+
+Binary sha256 `561b5316cd511de9fa9d8b8be4553da7add684f715d3bea533ca330ff7f3763c`; config bundle sha256 `3afb88d9fbbc4adc16083fa52a98cd4974583c6378a77a1a6e0ed8ae6d1b80c8`. Built from `1109092` (CI 2246 green). Both sections below are in it.
+
+### The tunnel re-key (D30) and the D4 bundle drop-in
+
+- **D30 (operator 2026-10-22: the agent makes a new key and registers it on the existing peer path).** When the latest
+  handshake stays stamped in the future for 15 minutes (the R-1204 sign: ep0 keeps the future timestamp and refuses
+  every newer handshake from that key), the agent makes a new WireGuard key pair, keeps the old private key as
+  `wg/private.key.prev` (0600 — the escrow may hold it), and registers the new public key through `POST /hosts/<id>/wg`.
+  The hub re-keys the peer IN PLACE (same /32, generation bump) and its full-list push to ep0 drops the old key and adds
+  the new one — nothing new runs on ep0. A new key is a new peer for ep0, with no stored timestamp, so the next
+  handshake is accepted. At most once an hour; not while the tunnel unit is down; never while a re-register is already
+  in flight. A failed registration is retried by the existing re-key-in-place path. Logs carry public keys only.
+  Tests `TestD30_*` (4), red-proved. A host-loss DR that installs the escrowed (older) key registers it again, and the
+  hub re-keys in place back to it — the same path.
+- **Review of the night's own code (felhom.eu `REPORT-night-2026-10-23.md`, N6, N7).** The rotation never leaves the box
+  without a readable key: the new key is written and fsynced to a temp file, the current key gets its kept name by a
+  hard link, then the temp file is renamed OVER `private.key` and the directory fsynced (a power cut or a kill between
+  two renames used to leave no key, or an empty one). `private.key.prev` keeps the FIRST old key (the escrow may hold it);
+  later ones are `private.key.prev.<unix>`, the newest three kept. The once-an-hour bound is saved in `wg/last-rekey`, so
+  an agent restart does not reset it; a start or a last re-key dated AFTER now (a clock that jumped back) is dropped,
+  never a block until that date (the commit's own security review). Tests `TestD30_TwoRotationsKeepTheFirstOldKey`,
+  `TestD30_ALastReKeyFromTheFutureDoesNotBlock`,
+  `TestD30_TheHourBoundSurvivesARestart`, red-proved. **Live (felhom.eu `audits/night-2026-10-23/P2-D30/`):** the D30
+  re-key ran on a test box (before these two changes): clock corrected → 15 min → new key registered → the box switched
+  at its next desired-state fetch → a handshake with the new key.
+- **D4 (operator ruling 2026-10-22, R-982) — root SSH from the LAN by key only, on `main` now (2026-10-23 day brief).** The
+  config bundle carries `/etc/ssh/sshd_config.d/10-felhom-root-key-only.conf` (`PermitRootLogin prohibit-password`;
+  content check: exactly that line, `sshd -t -f`). After an install that wrote it: `sshd -t` (the whole config), then
+  `systemctl try-reload-or-restart ssh` (a stopped or socket-activated sshd no longer refuses the bundle), then `sshd -T`
+  is read back and a drop-in that is NOT in force (no Include, an earlier drop-in, a Match block) is said loudly and
+  reported as `sshd_dropin_not_in_force` — never a refusal; an undone bundle reloads sshd again. The console and the
+  web page keep the root password; felhom-sshd (8822) is not touched. Tests `RootKeyOnly` (6), red-proved; the
+  installer's uninstall removes the file (felhom.eu installer 1.36.0). Reviewed 2026-10-23 night (A1–A7).
+- **Known gap, unchanged (filed):** after a reboot the kernel forgets the future stamp (latest handshake 0), so neither
+  this re-key nor the hub's alarm sees a box whose clock was corrected and which then restarted (R-1223).
+
+### The future-stamped handshake is reported (R-1204) — first written on the 2026-10-22 night
+
+- **R-982 / D4 — a ready patch on that night; on `main` since `1109092` and released in v0.163.0 (see above).** Built and proven the same night (felhom.eu
+  `audits/night-2026-10-22/P2-D4/`): a bundle drop-in `/etc/ssh/sshd_config.d/10-felhom-root-key-only.conf`
+  (`PermitRootLogin prohibit-password`), a `sshd` content check (exactly `prohibit-password`; `sshd -t -f`), and after
+  an install that wrote it `sshd -t` + `systemctl reload ssh`; tests `RootKeyOnly` (3), red-proved. Live on a fresh
+  nested box from ISO 1.30.0: root password over SSH refused, root key works, the console and the web page still take
+  the password. It was committed (`a0c88e5`) and moved back out (`7651461`): the installer's uninstall must remove every bundle file (felhom.eu `scripts/test_hostinstall.py`), the bundle half reaches a box only with an agent release, and the installer half only with a new `installer-v…` tag (R-110 — a push to `main` alone publishes nothing) — both forbidden tonight. *(Corrected the same night: the first reason written here, „a push of `felhom-host-install.sh` publishes the installer", was wrong — the website serves `/scripts/` from the tag `installer-v1.35.0`, read live in `manifests/webpage.yaml` and the running Deployment.)* Both halves are patches: `felhom-agent-bundle-D4.patch` and `felhom.eu-installer-D4.patch` in that folder; apply them together with the agent release and the next installer tag.
+- **R-1204 — `wireguard.handshake_future_s`.** A box that ran once with its clock ahead keeps a handshake stamped in the
+  future; ep0 refuses every newer one, and `last_handshake_age_s` (clamped at 0) read „just now" for ever. The heartbeat
+  now carries how many seconds the handshake lies ahead (> 60 s only); the age keeps its clamp. The hub alarms on it
+  (felhom.eu hub `wg_tunnel_stale`). Test `TestR1204_AFutureHandshakeIsReported`, red-proved.

+## v0.162.0 — every guest may swap as much as its RAM (R-1192, the 8 GB freeze); the host's swap is reported and checked; no false „operator access degraded" on a fresh box (R-1194) (2026-10-22) — RELEASED on the operator's yes; the vouch is the operator's

+`v0.162.0`; no `configs/` change since v0.161.0. Delivered by one signed `agent_update` job per box to demo-hp, Tester 1
+and demo-felhom (07:49–07:58 UTC): each `signed op COMPLETED`, `capabilities self-check ok=76 total=76`, `update
+committed`, then `guest-swap: raised` for its 9201 (512 MB → its RAM). Evidence felhom.eu
+`documentation/audits/morning-2026-10-22/release/04-agent-delivery.txt`. **Found at once:** demo-hp (host swap 8191 MB,
+guest swap 25898 MB) and demo-felhom (8191 MB vs 12288 MB) logged the host-swap WARN and the hub mailed
+`host_swap_short` — the check compares the host's swap with the guests' whole swap allowance, which a guest larger
+than the installer's 8 GB host swap always exceeds (felhom.eu register R-1216). Soak (night of 2026-10-21, 8 GB box):
+11 h, no freeze, the host's swap peaked at 2.7 GB used.
+
+
+The freeze of the rehearsal's first afternoon, reproduced and measured on demo-hp (felhom.eu
+`audits/fixes-2026-10-21/P4-freeze/`): Proxmox gives an LXC a 512 MB swap cap when nothing sets `swap`, and the agent
+never set it. On the 8 GB machine (guest 4096 MB) the first uploads made Immich load its analysis models; the guest hit
+its limit with the swap full and could evict only program code — 150 000–600 000 refaults and ~1 GB of disk reads per
+10 s, memory „full" pressure 92–95 %, load 155, the dashboard dead for 6½ minutes, no app killed. Raising the swap cap
+to 4096 MB live ended it within a minute while the uploads ran on.
+
+- `reconcile.buildBringUpConfig`: a new guest gets `swap` = its memory.
+- `POST /guest/memory` (RAM resize): `swap` moves with `memory` (`localapi.GuestSwapMB`).
+- At agent start (one minute in): `localapi.EnsureGuestSwap` raises every LXC in the `felhom` pool whose swap is below
+  its RAM to it — a live cgroup change, no restart; never lowers a higher swap; one guest's failure is logged and the
+  others are still done.
+- Tests `TestR1192_EnsureGuestSwapRaisesEveryLowSwapToItsRAM`, `TestR1192_BringUpSetsSwapToTheRAM`, the resize test's
+  new swap assertion — each red-proved (the write removed → `raised 0, want 2`; `swap=""` on both other paths).
+- Privilege: `swap` is under `VM.Config.Memory`, which the RAM resize already uses; no role, sudoers or bundle change.
+
+Added the night of 2026-10-21 (still unreleased, the same release):
+
+- **The host's swap is reported and checked (R-1192 follow-up).** The guest fix moves a memory burst onto the HOST's
+  swap; a host with none gets nothing from it. The host report carries `host.host_swap_mb` (Proxmox node status — the
+  kernel's SwapTotal, the same number as `/proc/meminfo`) and `host.guest_swap_mb` (the sum of the guests' `swap`; each
+  guest spec also carries `swap_bytes`). When the first is below the second the agent logs one WARN (and one INFO when
+  it is covered again); the hub raises `host_swap_short`. `GET /guest/memory` carries `host_swap_mb` and
+  `guest_swap_mb` for the controller's install page. The agent never creates host swap (a decision — felhom.eu
+  register). Measured the same night: our installer gives an 8 GB / 256 GB machine 7.75 GB of host swap.
+- **R-1194 — no false „operator access degraded" on a fresh box.** The first host report was sent before the
+  felhom-sshd loop's first pass, read a config that was never rendered („config invalid, port 0") and the hub mailed
+  `oob_degraded` — reproduced on a fresh install 2026-10-21 (the report at 20:34:00, the apply 0.4 s later, the daemon
+  healthy; the check runs `sshd -t` through sudo, so the non-root theory was false). The loop now reports no OOB stanza
+  until its first pass has run (a failed pass counts, so a real lasting failure still reaches the hub).
+- Tests `TestR1192_HostReportCarriesSwapAndWarnsOnce`, `TestR1192_GuestMemoryCarriesHostAndGuestSwap`,
+  `TestR1194_NoOOBStanzaBeforeTheFirstPass` — each red-proved.

+- **R-921 — `GET /backup/status` says when the host is busy.** New field `host_busy` (`{busy, what}`): whether the
+  host-wide heavy-operation gate is held right now (another guest's backup, the restore test, a night OS step, the
+  stale-lock sweep, a power-off) — the state that makes a `POST /backup` answer 409. Served on every request; absent
+  when the gate is not wired. Controller ≥ 0.335.0 reads it before it stops the household's apps for a tier, so a
+  refused tier costs no stop (the measured case of 2026-10-08: the night OS step, all 15 apps stopped for a refusal).
+  A read, never a reservation. No new route. Test `TestBackupStatus_R921_HostBusy`, red-proved (assignment removed →
+  `free gate: host_busy = <nil>`).
+- **R-1070 — a box with no tunnel set up no longer fails its host OS update.** Docker 29 prints „error: no such
+  object" in lower case, so the tunnel probe's case-sensitive match fell through to `unknown` („could not ask the
+  guest"), and the host health rule failed every box without a cloudflared container (Tester4, 2026-10-15,
+  `os_update_health_failed`). Now the match ignores case and a missing container is a new state, **`absent`** („no
+  tunnel set up on this box"); the host rule reads it as not applicable only when the reading from before the update
+  (Docker answered) also had no cloudflared container. A tunnel that is down, gone or unreadable still fails. The hub
+  alarms only on `not_running`, so `absent` never mails. Tests `TestHostHealthVerdict_R1070_NoTunnelSetUp` (7 rows) and
+  three `TestClassifyTunnel` rows (Docker 29's wording measured on demo-hp), red-proved both ways.
+- **R-1010 — the stale-lock janitor clears a half-removed `vzdump` snapshot.** When the delete fails ONLY with
+  „Failed to find logical volume …_vzdump" (one disk's snapshot already gone — demo-hp 2026-10-14 after a backup ran
+  out of space), it retries once with Proxmox's own `force=1` on the same API call (`DeleteSnapshotForce`; the same
+  token privilege, no sudoers line, no root command — `pvesh usage … -command delete` lists `--force`). Any other error
+  is returned unchanged; a failed forced delete is returned, never a second force. Tests
+  `TestStaleLock_R1010_ForcesOnceOnlyWhenTheVolumeIsGone` (6 rows) and `TestDeleteSnapshotForce_R1010`, red-proved
+  (single plain delete → `calls [plain], want [plain force]`).
+
+- **The security-scan gate (R-986), tooling only:** `agent_gates.py` registers the SHARED
+  `felhom.eu/scripts/security_scan_gate.py` (FAST set: the hook and CI) — govulncheck (called vulnerabilities) and gitleaks
+  on the pushed commits, **warn-first**. `.security-accepted` holds the first scan's 15 accepted hits (escrow and
+  local-API test constants), each with a reason. CI fetches the pinned gitleaks (`FELHOM_SCAN_FETCH=1`). Decoys: the
+  shared 8 plus the gate on this repo, in `test_gate_decoys.py`.

+### Earlier on 2026-10-19 (texts only)

+- The ceremony-complete log line now says the package uploads at the claim **or at the typed-back confirm** (R-1151);
+  it read „package uploads at the claim" for both orders (seen in demo-hp's journal, 2026-10-19 01:47 UTC).
+- The R-973 comments in `cmd/felhom-agent/main.go` and `internal/localapi/backup_cap.go` named the hub event
+  `agent_capability_degraded`; since hub v0.159.0 (R-1150) a refused backup raises `whole_guest_backup_refused`.
+  Found by the hub helper of the day brief 2026-10-19.
+- **gofmt, R-1160:** `1edfd8e` formats the 14 Go files that were not gofmt-clean (formatting only, `go test ./...`
+  green). New gate `scripts/gofmt_gate.py` (the controller's R-454 shape) in `agent_gates.py`, fast set; its decoys in
+  `scripts/test_gate_decoys.py` plant an unformatted file in a SCRATCH copy (convicted by name), the formatted twin
+  (passes), and the no-Go modes (CI passes out loud, a dev machine is INCONCLUSIVE). Red-proved: with the conviction
+  switched off the FACT case reports a LIVE HOLE. The next release carries it; no release for it.
+
+## v0.160.0 — five fixes: an abandoned or un-typed-back escrow ceremony keeps the old code (R-978, R-1151); a whole-guest backup flood is capped (R-973) and the local tier keeps one point per day (R-1149); an empty partition is not „data" (R-1093) (2026-10-19)
+
+Released 2026-10-19 on the operator's yes (02:48 answers, D17 „one per day, 3 days"). sha256
+`7ebb547f2b1ab93544ba828d3040351b60c4126327a5b85bbcb33f8f2b3dfca1`, config bundle
+`6b06090190ff609af1fe9842447ebf385fd52da4be382bc7ca708b558c8e202f`. The vouch is the operator's.
+
+- **R-1093 — an EMPTY partition no longer asks the typed „data will be erased" confirmation.** `lsblk` prints the
+  parent disk's table type (PTTYPE) on every partition, so `SudoHostOps.InspectDevice` read a blank partition as
+  „device has a partition table". Now lsblk's PTTYPE is set aside only when `blkid -p` on the partition itself proved
+  it read the device and that it is a partition of a table of exactly that type (`PART_ENTRY_NUMBER` +
+  `PART_ENTRY_SCHEME` equal to lsblk's PTTYPE). The partition's own signatures still come from `blkid -p`: a
+  filesystem or a nested table inside it stays data-bearing; a blkid that printed nothing, a whole disk, or a scheme
+  that differs keeps the old, safe reading. **No new command, no sudoers or config-bundle change** (the two probes are
+  the same allow-listed argv). Test `TestInspect_R1093_PartitionVerdicts` (8 rows), red-proved: with the old
+  `if pttype != ""` both empty-partition rows fail `DataBearing=true reason="device has a partition table"`.
+  **Hardened after the same night's review (fail-closed on every path):** `PART_ENTRY_*` is read from the PARENT's
+  table, so lsblk's PTTYPE is set aside only when blkid also **exited 0** — exit 2, an I/O error or a missing binary
+  keep „device has a partition table"; and an `lsblk` that exits 0 with output that does not parse into a device (or
+  lists none) now leaves the device UNPROBED („could not be reliably inspected") instead of „blank" — that hole
+  predates R-1093. Six more rows in the same test, each red-proved (`blkidErr` check removed → „device is blank";
+  `&& parsed` removed → `Probed=true … „device is blank"`).
+- **R-978 — an abandoned second escrow ceremony no longer makes the customer's recovery code useless.** The root
+  ceremony (the FELHOM_ESCROW argv, unchanged: `--upload --output=json`) used to upload the new package before the new
+  code was claimed, and the hub overwrites the current package when the sealed secrets are unchanged — so a customer
+  who started the ceremony again and walked away (or an agent restart in the 10-minute window) was left with a
+  written-down code that opened nothing. Now json mode hands the package back (`CeremonyOutput.PendingUpload`, output
+  **version 2**; text mode still uploads at once) and the daemon uploads it at `POST /escrow/ceremony/claim`, **before**
+  the code is handed out (`EscrowCeremonyConfig.Upload` → `putEscrowBody`, the same PUT and per-host key). A failed
+  upload answers 502 and keeps the code claimable; the TTL and a new start wait while the claim's upload is in flight;
+  no uploader → 503; an output that uploaded by itself or carries no package fails the ceremony. Status `uploaded`
+  now reads false until the claim. The controller is unchanged (it never read `uploaded`; its claim already assumed
+  the package is on the hub when the claim returns). **No sudoers or config-bundle change.** Tests (localapi)
+  `TestEscrowCeremony_R978_*` (abandon by TTL / by a new start / by a restart → the hub's package still opens with
+  code 1; claim stores before handing out; upload failure; in-flight TTL; no uploader; no package) and (cmd)
+  `TestEscrowOptsFromCLI_JSONModeDefersUpload`, `TestDeliverEscrowPackage_JSONModeSendsNothing`,
+  `TestR978_CeremonyUploadIsWiredIntoTheDaemon`. Red-proved: upload-at-create restored → „code 1 no longer opens it
+  (uploads=2)"; the in-flight TTL guard removed → „the TTL voided the code while its package was uploading";
+  `deferUpload: false` → „json mode must defer the upload"; the `Upload:` line removed → „has no Upload". **Residual:**
+  the customer's typed-back check after the claim is browser-only, so „confirmed" here means „claimed" — a customer
+  who opens the code and closes the page without writing it down has replaced the package.
+- **R-1151 — the new recovery code replaces the hub's package only after the household typed it back.** R-978 moved
+  the upload to the claim; but the wizard's typed-back check was the browser's alone, so a household that opened the
+  new code and closed the page without writing it down had already replaced the package their old code opens. Now a
+  claim with `{"defer_upload": true}` (controller ≥ 0.332.0) hands out the code with two word positions
+  (`verify_positions`, drawn by crypto/rand) and keeps the package; the new `POST /escrow/ceremony/confirm
+  {"words": [w1, w2]}` checks the two words (constant time, case and spaces aside) and only then uploads it. Right → 200;
+  wrong → 422, still waiting; one word → 400; nothing waiting → 404; the 30-minute window ran out → 410 and the job
+  reads `unconfirmed_void` (the package dropped, the previous code still works); hub failure → 502, still waiting. Only
+  the two words are kept for the check, never R; a new start, the window and a restart drop them with the package.
+  Status gains `awaiting_confirm` and `confirm_expires_in_sec`. **An old controller (≤ 0.331.0) claims with `{}` and
+  never confirms: it keeps the R-978 order (upload at the claim)**, so its household's ceremony still completes; a new
+  controller on an old agent sees no `confirm_required` and needs no confirm. No sudoers or bundle change. Tests
+  `TestEscrowCeremony_R1151_*` (shown but not typed back — by the window, a new start, a restart — code 1 still opens
+  the hub's package; typing; the old controller's order; hub failure at the confirm) and `TestPickConfirmPositions`.
+  Red-proved: the defer flag ignored → „a code that was shown but never typed back replaced the package: code 1 no
+  longer opens it (uploads=2)" in all three; the word check skipped → „one wrong word: got 200 (uploads=1)".
+- **R-1149 — the local whole-guest tier keeps one restore point per day for 3 days** (operator decision D17,
+  2026-10-19). The primary (local) tier's per-run prune is now `--prune-backups keep-daily=N` (N =
+  `local_backup_retention`, default 3) instead of `keep-last=N` — the same at most 3 archives, but a run of extra
+  backups inside one day replaces only that day's point, so with the R-973 cap a flood cannot push out the earlier
+  days' copies. Additional tiers keep their explicit `keep_last` (the weekly off-site „last 2" is two weeks).
+  `config.BackupTier.PruneSpec()` is the one place the spec is built (runDaemon used to format keep-last itself); the
+  „backup tier armed" log line names it. Tests `TestBackupTierPruneSpec_R1149_LocalKeepsOnePerDay` and the
+  consequence `TestBackupCap_R1149_LocalFloodKeepsOlderDays` (the agent's real spec, a Proxmox-shaped prune model,
+  three nights then a day-long flood → the two earlier nights survive). Red-proved: keep-last for the primary →
+  „primary tier prune = "keep-last=3", want "keep-daily=3"" and „holds 0 copies made before the compromise". No
+  config or sudoers change.
+- **R-973 — the local-API whole-guest backup route has a cadence cap.** Every successful run prunes its tier, so a
+  compromised controller calling `POST /backup` in a loop pushed out every pre-compromise restore point (local
+  keep-last 3; off-site via ep0's keep-last 2). Now (`internal/localapi/backup_cap.go`): a tier whose cadence is ≤ 24 h
+  allows **3 successful runs per rolling 24 h** (the `07` §6 day: the night run, a „Mentés most" press, and the next
+  night, which since R-899 still runs and can land inside the same 24 h — so a press never costs the night); a longer
+  tier allows **1 per max(cadence − 24 h, cadence/2)** — 6 days for the 7-day off-site tier, which the controller only
+  runs when due and the button never targets. Only successes count (a failed run prunes nothing). A refusal answers
+  **429** with the next allowed time, is logged at WARN, is saved, and for 24 h raises the CRITICAL host-report status
+  `localapi:backup-cadence-cap` — the hub's existing operator-only `agent_capability_degraded` event, **no hub change**.
+  **The cap survives an agent restart:** `BackupSuccessState` (the R-894 file) now also keeps the newest 8 success
+  times and the last refusal per tier and guest (additive JSON fields; a pre-R-973 file counts its one known
+  success). Tests `TestBackupCap_*` (an off-site flood keeps a pre-compromise copy for 5+ days; a local flood runs 3
+  a day; the scheduled day is never refused; restart; failures; the operator signal) + `TestBackupCadenceCap`,
+  `TestBackupSuccessState_R973_*`, `TestBackupCapStatus_*`, `TestR973_CapRefusalIsWiredIntoTheReport`. Red-proved:
+  the cap disabled → „the off-site tier lost every pre-compromise copy: 10 runs"; the disk history ignored → „after a
+  restart the 4th run in a day was allowed"; the wiring line removed → „never binds backupCapRefusal". **Limits, stated:**
+  with keep-last 3 the local tier's three points can still be replaced within one day (3 per day is the schedule's own
+  pace plus one press); the hub's event text reads „agent privileged capability degraded" (the type is generic). No
+  sudoers or bundle change.
+- **CI workflow (R-1135, no code change).** `.gitea/workflows/gates.yml`, the alarm step: the mail's run link is now `https://gitea.dooplex.hu/<repo>/actions/runs/<run id>`.
+  It used `GITHUB_SERVER_URL`, which on this runner is the in-cluster address (`http://gitea.gitea-system.svc.cluster.local:3000`,
+  the address the runner registers at), so nobody outside the cluster could open it. It also used the run NUMBER, and
+  Gitea 1.26 reads `/actions/runs/<n>` as a run id first: a number that is also an older run's id opened that other run
+  (measured 2026-10-18: `felhom.eu/actions/runs/1116` opened run id 1116, run number 613). It now uses `GITHUB_RUN_ID` and
+  prints the link (`ALARM-LINK …`) into the job log. Same change in all four repos' workflows.
+
+## v0.159.2 — the orphan thin check runs only after a failed backup (R-1012 follow-up) (2026-10-18)
+
+**Released 2026-10-18 (committed 2026-10-17): sha256 `4d98868e922d6c10665a6c0da9323e8627ea9c589094e81d27d741e625d9d8f9`, bundle `477704ea2980948433ffc34bb59f008cc11410fd9683d386bfd3e2f085d55bc9`; the vouch is the operator's.** No `configs/` change since v0.159.1. The independent review of 2026-10-18 found nothing in it. v0.159.0/v0.159.1 ran the R-1012 orphan check
+before EVERY snapshot-mode whole-guest backup, and that check takes a short metadata snapshot of the live thin pool.
+Now `BackupRunner` runs it only when the snapshot step has failed (the vzdump start or its task) — the moment the
+answer is needed. The finding is still appended in plain words to the failed backup's error, exactly as before; a
+successful backup never runs the check and keeps a clean record; stop mode and an unwired runner are unchanged. The
+`thin-orphan-check` capability text says „after a failed whole-guest backup". Tests
+`TestBackup_SnapshotFailure_NamesTheOrphan` (now: exactly 1 call, after the failure) and
+`TestBackup_ThinCheck_SilentWhenNotApplicable` (now: 0 calls on a successful backup), red-proved against the v0.159.1
+`runner.go`: failure legs „thin check ran 2 times, want 1", success leg `calls=1`. No root file, sudoers or bundle
+change. (Installer side, felhom.eu, same night: `felhom-host-install.sh --rotate-recovery-only`, R-1141.)
+**Proven live 2026-10-18 (demo-hp):** a green snapshot backup with 0 `felhom-thin-check` calls (the 0.159.1 night backup
+had 1). The failed leg stays covered by the fixture test.
+
+## v0.159.1 — the signed decommission prunes the guest-bind record (found by v0.159.0's own live proof) (2026-10-17)
+
+**v0.159.0 is superseded — do not vouch it.** Everything of v0.159.0 below, plus: `signedjobs.DecommissionExecutor`
+drops the drive from every guest's bind record (`SetGuestBinds`, wired to the agent's `GuestBindStore`), as the
+self-serve decommission always did. Without it a drive decommissioned by an operator-signed job and then forgotten
+(R-1124) left a record the 20-second guest-bind re-assert warned about every tick („reconcile: skipping non-enrolled
+drive") — seen on demo-hp minutes after the R-1124 proof. Test `TestDecommissionExecutor_PrunesTheGuestBindRecord`,
+red-proved. Released: tag `v0.159.1`, sha256 `de8f6ad9…aff9`, bundle `2af3d27d…7cd6` (the same root files as v0.159.0).
+**Not vouched.** Delivery to a box on the v0.158.1 bundle: `agent_update 0.159.1` → `agent_config_update 0.159.0-step1`
+(sha `1d65edb3…d6cf`, published) → `agent_config_update 0.159.1` (the bundle adds `felhom-thin-check`, R16).
+
+## v0.159.0 — forget a decommissioned drive that is gone (R-1124); name an orphan thin device in a backup failure (R-1012); Go 1.27.2 (R-972) (2026-10-17)
+
+**Superseded by v0.159.1 — do not vouch.** Task: „agent release, the catalog allow-list, break-glass rotation, off-site
+history check" (felhom.eu `REPORT-agent-allowlist-rotation-2026-10-17.md`).
+
+- **Go 1.27.2 + x/crypto v0.58.0** (R-972, `37b99d7`): the first release that carries them (v0.158.1 was built with
+  go1.26.0).
+- **R-1124 — a decommissioned drive that is gone is forgotten.** `SudoHostOps.ForgetRetiredDrives` (agent start and the
+  20-second storage tick): for a Felhom drive unit whose intent is `decommissioned`, whose `/dev/disk/by-uuid` link is
+  gone and which is not mounted, `systemctl disable` + the new root verb `felhom-priv-apply unit-forget <unit>` +
+  `daemon-reload`. The unit is gone, so a later boot no longer waits for the drive and the agent stops listing it (no
+  „absent by UUID" line every 20 s). A decommissioned drive still plugged in KEEPS its unit and raw mount, so the
+  one-click re-enroll (H3) still works. `unit-forget` re-checks as root: a felhom by-UUID drive unit (not a network
+  unit), disabled, its `Where` not mounted, its by-UUID link absent — otherwise refused. Sudoers `FELHOM_MOUNT` gains the
+  one verb. Tests `TestForgetRetiredDrives_*` and `configs/test_felhom_priv_apply.py` `UnitForget`, red-proved.
+  **Live on demo-hp:** a loop-backed test drive enrolled through the local API, decommissioned by a signed job (kept
+  its unit while present), unplugged → 8 s later the unit and its wants link were removed and `GET /disks` dropped it.
+- **R-1012 — an orphan thin device is NAMED in the backup failure, never removed.** New READ-ONLY root helper
+  `felhom-thin-check <vg> <pool>` (config bundle): LVM's thin ids before and after, the pool's ids through a metadata
+  snapshot it reserves and releases (refuses — exit 3 — when someone else holds one; releases on every exit; sends no
+  other pool message). `internal/thincheck`: an orphan = in the pool and in neither LVM list, on two reads 3 s apart;
+  fails open. `BackupRunner.SetThinCheck`: before a snapshot-mode backup (a WARN when found) and again after a failure —
+  the finding is appended in plain words to the error the controller mails to the operator, pointing at the new
+  runbook `whole-guest-backup-orphan-thin.md`. Sudoers `FELHOM_THINCHECK`, capability `thin-orphan-check`. Tests
+  `internal/thincheck`, `TestBackup_SnapshotFailure_NamesTheOrphan`, `configs/test_felhom_thin_check.py`, red-proved.
+  **Live on demo-hp:** on a scratch thin pool (a loop file on `/mnt/hdd_1`, never `pve/data`) the helper listed a made
+  orphan (device 7) and refused a snapshot held by someone else; on `pve/data` it read 1, 2 = LVM's and released; a
+  normal whole-guest backup of 9201 ran the check first and finished green.
+- Released: tag `v0.159.0`, sha256 `3cfd0a25…edfed5`, bundle `40663c4f…6d681`; step bundle `0.159.0-step1`.
+
+## CI only — a manual proof that the failure mail can be sent (R-1129, 2026-10-17)
+
+No agent release; no binary changes.
+
+`.gitea/workflows/gates.yml` gains a manual `workflow_dispatch` trigger with one input, `force_alarm` (default false), and
+one step that runs ONLY on a dispatch: it prints the length of `RESEND_API_KEY` (never the key) and, with
+`force_alarm=true`, fails on purpose so the existing alarm step sends its real mail; the mail's subject then starts
+„FORCED TEST, not a real failure". A push run is unchanged: the new step is skipped and the subject is the old one. Same
+change in all four repos' workflows. Purpose: prove the failure mail now goes out after the operator set the key
+(every failed run until today ended „ALARM FAILED: RESEND_API_KEY is empty").
+
+## scripts only — the decoy suite is a gate of the full run (R-1116, 2026-10-17)
+
+No agent release; no binary changes. `scripts/test_gate_decoys.py` is now the `gate-decoys` row of `agent_gates.py`:
+the full run (which CI runs on every push), not `--fast` — it takes ~20 s in the workspace (measured: 30 cases; ~5 s in a
+CI-shaped shallow clone, also green). It was in no runner, the shape that let the catalog's R-1115 fail unseen for a
+night. It plants only in scratch clones and asks a fake Gitea on 127.0.0.1; it does not call the runner (no
+recursion). Declared in its own `COVERS`; `test_agent_gates.py` pins it (registered once, full run only, named by
+`--fast`'s SKIPPED line). Red-proved: a reuse-refs FACT case flipped to expect rc 0 turned the full run red
+(`CONVICTED: gate-decoys`); restored, green. CLAUDE.md's `--fast` sentence names it.
+
+## unreleased — Go 1.27.2 and golang.org/x/crypto v0.58.0 (R-972, 2026-10-16)
+
+**Not released, not deployed** — agent releases wait for the operator's vouch; the next vouched release carries this.
+`go.mod`: `go 1.27.2` (was 1.25.0; the shipped 0.158.1 binary was built with go1.26.0), x/crypto v0.58.0 (was v0.52.0),
+x/sys v0.49.0. `go build`, `go vet`, the full `go test ./...` and `agent_gates.py --fast` green on Go 1.27.2.
+`release-agent.sh` builds with the toolchain `go.mod` names (GOTOOLCHAIN=auto), so no script change.
+
+## scripts only — `release-agent.sh` refuses when the registry cannot say the version is new (R-1098, 2026-10-16)
+
+No agent release; no binary changes. `scripts/release-agent.sh` already refused a version whose tag exists or whose
+package answers 200. It let everything else through — a registry it could not reach (curl prints `000`) or a 500 read
+as „new". Now only a clean `404` proves the version is new; anything else refuses with the code it got. New
+`scripts/test_release_push_once.sh` (the real script, a fake `curl` and `go` on PATH; published / absent / unreachable /
+server error / tag exists), red-proved: with the 404 rule removed, the unreachable and server-error cases fail. Same rule
+as the controller `build.sh` and, since today, felhom.eu `scripts/build-hub.sh`.
+
+## v0.158.1 — security review of v0.158.0: the mkfs wrapper trusts no sibling claim; the internal-place helper fails closed (2026-10-16)
+
+**v0.158.0 is superseded — do not vouch it.** A security review of `912f7c1` found two defects; both fixed here, each test
+seen failing against the 0.158.0 script:
+- **`felhom-mkfs-guarded`**: 0.158.0 let a format through when a SIBLING part was mounted at /mnt/<name> AND under
+  /mnt/felhom-drives („Felhom's own drive"). That corroboration is a mount the agent can make itself, so a compromised agent
+  could unlock a host owner's disk — the exact case this root wrapper exists for. Removed: any mount of any node outside
+  /mnt/felhom-drives refuses again (now read from the kernel's mount table for every node; an unlistable disk refuses).
+  Consequence: the free part next to an in-use Felhom drive cannot be formatted — `CandidatePartition.Formattable` is false
+  for every part of a disk with a mounted node, and the controller does not offer it (a part with a filesystem can still be
+  USED). Pinned by configs/test_felhom_mkfs_guarded.py + partitions_test.go.
+- **`felhom-internal-place`**: a failed `lvs` listing read as „nothing promised" (a too-large place) and a `blkid` error read
+  as „no signature" (the only gate before mkfs). Now: a failed listing, a listing without the pool, or any blkid exit other
+  than 0/2 REFUSES. Three new tests, all failing against 0.158.0.
+- Released: tag `v0.158.1` (code `98f3cdd`), sha256 `20264df6…84b76a1`, bundle `c23c3d35…cb1c41b`. **Not vouched.**

+## v0.158.0 — the internal data place; partitions as places; add_internal_place (2026-10-16)
+
+Design: felhom.eu `architecture/16-storage-physical-identity.md` §5, §6, §7, §9 (operator rulings D3–D5; the D3 sizes
+ruled 2026-10-16 after the space check, felhom.eu `audits/storage-identity-buildB-2026-10-15/SPACE-CHECK.md`).
+
+- **The internal data place („Belső tárhely")** (`internal/localapi/internalplace.go`): when the record
+  `/var/lib/felhom-agent/internal-place.json` names a filesystem, the agent mounts it at `/mnt/belso` by fs-UUID like an
+  enrolled drive (startup + every 20 s tick) and records it `enrolled`; `GET /disks` reports it with kind `internal`.
+  It never takes `/mnt/belso` from a household drive, and eject/decommission/format of it are refused (device-mapper on
+  the system disk). Its identity is the system disk's, so build A never counts a copy to `sys_drive` as a second copy.
+- **Root helper `configs/felhom-internal-place`** (new in the bundle): `plan|create <planned GiB>` — the ruled size rule
+  (reserve max(16 GiB, 10 %) ≤ 48 GiB, made only when ≥ 20 GiB, nothing promised beyond pool − reserve), the only
+  lvcreate/mkfs of a system-disk volume; formats only a `felhom-belso` with no signature. Run by the installer (1.33.0)
+  and by the new signed op.
+- **Signed op `add_internal_place`** (old one-disk boxes, `16` §9): no parameters (the size is the rule's), destructive
+  class (operator key). Runs the helper with `create 0`, writes the record, mounts.
+- **Partitions as places** (`internal/storage/partitions.go`): `GET /disks/candidates` lists each partition of a free
+  disk as empty / filesystem / in_use. A data-bearing part's wipe id binds disk id + part number + fs-UUID
+  (`byid:<…-partN>+fsuuid:<uuid>`); both must name the same device at format time.
+- **`felhom-mkfs-guarded`** (REVERTED in v0.158.1): a SIBLING part that is Felhom's own drive no longer blocked formatting
+  the free part next to it. First tests of the wrapper: `configs/test_felhom_mkfs_guarded.py`.
+- `configs/` changed (sudoers `FELHOM_INTERNALPLACE`, the helper, the wrapper, the bundle list) — **a config-bundle job
+  is needed** with the agent update. **Not vouched** (the operator's act).
+- Released: tag `v0.158.0` (code `912f7c1`), sha256 `a3589d1d…2caba`, bundle `17066273…fb5c76`. **Superseded by v0.158.1 —
+  do not vouch** (its mkfs wrapper trusted a sibling claim the agent can fake; its helper failed open).
+
+## v0.157.0 — every storage place knows its physical disk(s); POST /disks/same-disk (2026-10-15)
+
+Design: felhom.eu `architecture/16-storage-physical-identity.md` §3, §4, §10 (operator rulings D1–D6, 2026-10-15). Spike:
+felhom.eu `audits/storage-identity-2026-10-15/`.
+
+- **Identity of a storage place** (`internal/storage/identity.go`): the physical disk(s) under it, from `/sys`, `/run/udev/data`
+  and `/proc/mounts` only — partition → disk, device-mapper / LVM thin → slaves, loop → backing file → its disk. Keys:
+  `eui:` (NVMe), `serial:<bus>:<model>:<serial>`, `wwn:` only without a serial and only with a vendor (OUI ≠ 000000).
+  `proven`, or `unknown` with one reason: `vm` (systemd-detect-virt), `network`, `usb_bridge` (a placeholder serial — the rule
+  is the design's, UNPROVEN on a real enclosure, R-1077), `weak_wwn`, `no_serial`. No block I/O.
+- **Reported:** `GET /disks` rows and the hub report's `storage_targets` gain `kind`, `physical_disks`, `identity`,
+  `identity_reason` (additive; the golden and the hub's copy change together). A dir storage is judged only on its OWN mount — an
+  absent drive is "not computed", never the root disk.
+- **`POST /disks/same-disk`** `{a, b}` (guest paths) → `{different, proven, reason, a, b}`. Maps `/mnt/felhom-drives/<name>` to
+  the host mount at exactly that path, and `/mnt/sys_drive`, `/var/lib/felhom`, `/var/lib/docker` to the guest's data volume's
+  storage. Anything else, or an absent drive → `unmapped`. A shared disk key is "same, proven" even when the disk is unknown.
+  Scoped like every `/disks` call.
+- Tests: fixture `/sys` + udev trees for every spike case (one disk LVM thin, two disks, two partitions, a loop on a file, NVMe eui,
+  vendor-less WWN, a VM, a USB placeholder serial, a network share) and the same-disk call (equal, different, VM, NAS, absent
+  drive, scope); red-proofed (the LVM "diamond" bug was seen failing first; the VM, WWN, own-mount and sys_drive rules broken on purpose).
+- `configs/` unchanged — no config-bundle job needed. **Not vouched** (the operator's act).

-Evidence: felhom.eu `documentation/audits/power-cut-fixes-2026-10-14/` — the spike (C1 the night's leftover, C2 a killed
-worker, C3 a real power cut, C4 a full disk), the 17 red-proofs.
+**Plain words first.** The operator can now restart a box's controller from the hub's host page. The agent does it, so it
+works when the controller is stopped or stuck. It uses the supervisor's own guards and brake: 3 restarts in 15 minutes,
+then presses are refused for 30 minutes. A controller that runs but does not answer now raises an operator alarm
+(`controller_unresponsive`); it is not restarted by itself yet — that waits for the night's measurement (R-1344).
 
-## What the spike showed
+## Commits
 
-- A power cut mid-backup leaves `vzdump-lxc-<vmid>-<date>.tar.dat` + `.tmp/` (root, in `/var/lib/vz/dump`); Proxmox never
-  lists it as a backup; nothing removes it; every later backup is skipped „not enough space".
-- The dead vzdump task stays in Proxmox's active list ~30–60 s after the boot — long enough for the agent's start-up pass
-  to call it „genuinely in flight" (R-1008). Short, so R-1008's harm is small.
-- A killed worker leaves `tar`/`zstd` writing into the `.tar.dat` for minutes, none named „vzdump" — the reason the root
-  helper checks open files, not only process names.
-- On „No space left" vzdump removes its own partial (both paths): the preflight's sizing stays. But a full host root breaks
-  LVM's own metadata writes (a half-removed snapshot; the janitor cannot clear it — new row).

One audit line, one result per id, re-sent until the hub records it; a report is asked for at once. R-1344: 6 unhealthy sweeps → `unresponsive_since` in the stanza.

-## 0.156.0 is superseded — do not vouch it
+## Release
 
-A background security review of the pushed 0.156.0 flagged „fail-open state drift": its in-flight rule compared a task's
-wall-clock start with the kernel's `btime`, which moves when the clock is corrected after the boot (an NTP step after a
-power cut) — a live backup could then look „from before the boot" and its lock be cleared. 0.156.1 uses Proxmox's own
-liveness rule instead (the UPID's pid + pstart against `/proc/<pid>/stat` start tick and state; no clock), and fails safe
-when this agent cannot see root's processes (PID 1 not visible).

A pre-R-86 file (bare RFC3339 per target) keeps its time and yields NO proven archive, so each tier is due once after the upgrade; reading a legacy time as proof of the current archive would invent a guarantee. **R-189: it is also the REPORTABLE half of the restore-test signal.** The in-memory `backup.Store` holds only this process's latest run, and under per-archive due-ness the agent will not re-test a proven archive — so a proof lost to a restart is not repeated for a whole archive generation (observed live: a passing 14.5 GB offsite restore reached no host-report). `ProvenRestoreTests` renders the stored proofs as `hub.RestoreTest` entries and the collector merges them; a record missing the archive or the tier is NOT emitted, because an unproven tier reading as proven is worse than the defect. **Only successes are stored, deliberately:** a success suppresses future work, a failure causes it. |

+# felhom-internal-place — make the one-disk box's internal data place („Belső tárhely"), felhom.eu
+# architecture/16-storage-physical-identity.md §5, §7 (sizes ruled by the operator 2026-10-16). Installed as
+# /usr/local/sbin/felhom-internal-place (config bundle). Called by felhom-host-install.sh (a new box) and by the agent's
+# signed `add_internal_place` job (an old box) — ONE implementation of the size rule and of the only mkfs it does.
+#
+#   felhom-internal-place plan   <planned GiB>   → prints the numbers, changes nothing
+#   felhom-internal-place create <planned GiB>   → makes the place (or finds it), prints the result
+#
+# <planned GiB> is thin space still to be promised to the guest (rootfs + data volume) that does not exist yet:
+# the installer passes 32 + the data volume; an old box passes 0 (its guest's volumes are already counted).
+#
+# The rule (16 §7, ruled): reserve = max(16 GiB, 10 % of the pool), at most 48 GiB; internal = pool − reserve −
+# every thin volume already promised in the pool − <planned>, made only when ≥ 20 GiB. So nothing in the pool is ever
+# promised beyond pool − reserve: a pool at 100 % stops every volume on the box.
+#
+# It trusts nothing it is told. Every rule is checked here, as root, and any doubt REFUSES (exit 1):
+#   - the pool is the `lvmthin: local-lvm` section of /etc/pve/storage.cfg (its vgname/thinpool), nothing else;
+#   - the only volume it creates, formats or reads is <vg>/felhom-belso;
+#   - it formats ONLY a felhom-belso that carries no signature at all (blkid -p finds nothing) — the one it just made,
+#     or one a crash left between lvcreate and mkfs; any other content REFUSES; it never resizes or removes anything.
+# Output, one line: „created uuid=<fs-uuid> gib=<n>", „formatted uuid=… gib=…" (a crash left it empty), „existing uuid=<fs-uuid> gib=<n>", „skipped <why>" (exit 0),

+#
+# Reading the live pool's device list needs a metadata snapshot: the kernel's documented way to read metadata while
+# the pool is in use (`reserve_metadata_snap`, `thin_ls --metadata-snap`, `release_metadata_snap`). It changes no data
+# and no mapping; it is held for the length of one `thin_ls -o DEV` (well under a second on these pools). Rules:
+#   1. the arguments are an LVM name pair; <vg>/<pool> is a thin pool (lv_attr starts with `t`);

+#      refuses (exit 3) and does not release it;
+#   3. LVM's list is read before AND after the pool's, so a volume created in between is not reported as an orphan

+"""Tests for configs/felhom-mkfs-guarded.sh — the ONLY mkfs path the agent's sudoers permits.
+
+First tests of this wrapper (agent v0.158.0), written for partitions as places (felhom.eu architecture/16 §6). Every
+mount of every node of the disk outside /mnt/felhom-drives refuses — INCLUDING a sibling that is Felhom's own drive
+(its raw /mnt/<name> mount): the agent can make that corroborating mount itself, so the root wrapper must not trust
+it (security review of 912f7c1). An unlistable disk refuses.
+
+HOW IT RUNS ANYWHERE: the wrapper is copied with five literal host paths replaced (each replacement is asserted, so a
+drifted wrapper fails here instead of silently testing nothing): /proc/mounts → a fake mount table, the block-device
+test → true (no real /dev nodes here), the pvs candidates → a stub, /sys/block → a fake tree, the mkfs binaries → a
+recorder. `lsblk` is a PATH stub answering the three calls the wrapper makes from one JSON disk description.
+Every refusal has a positive control (the same disk without the one condition is formatted).
+Run: python3 configs/test_felhom_mkfs_guarded.py   (also run by the Go suite, internal/storage)

+// Package linetest is the weekly upload line-speed test (R-1247; operator ruling 2026-10-24 07:26).
+//
+// Why: the controller's upload watch and qBittorrent's default limit (50 % of the line, D41) need the household's
+// upload line. The passive reading — the nightly off-site push — is only a low floor (2026-10-24 night: demo-hp „at
+// least 10 Mbit/s"; this test read 90.7 on the same line). So once a week the HOST (the tunnel lives on the host)
+// runs a 10-second iperf3 upload to ep0's tunnel-only iperf3 server (felhom.eu scripts/ep0-iperf3). No file is left
+// anywhere and nothing counts against the household's storage.
+//
+// The rule, each part pinned by a test in linetest_test.go:
+//   - Weekly: due from Tuesday 10:00 local until one measurement succeeded since then (a box that was off catches up
+//     on a later day, inside the window).
+//   - Daytime only: a test starts only 10:00–15:59 local — never in the night chain's window (01:00–06:59), and each
+//     host starts from its own minute (SlotMinute, spread over 10:00–13:59) so the fleet does not test at once.
+//   - Never beside a backup, a restore-test, an OS update or a trim: the test holds the host-wide one-heavy-op gate.
+//   - Only after QuietMinutes of quiet uplink: every one-minute transmit rate of the host's physical uplink below
+//     QuietMbps — so neither the family's upload nor a restore is measured against itself.
+//   - Up to RunsPerMeasurement runs of TestTime each; the highest counts. A run is bounded by RunTimeout.
+//   - „Server busy" (another box is testing) → tried again at the next tick the same day; at most MaxTriesPerDay.
+//   - No tunnel (no operational wg-felhom with a server address) → no test and no value; the controller then keeps its
+//     passive floor and sets no qBittorrent limit.
+//   - The last result is persisted, so a restart neither loses it nor re-tests.
+//   - A box whose torrent app seeds all day is never quiet for 10 minutes (R-1250). For it the controller holds the
+//     app's upload limit very low and asks for a test on request (RunNow): every rule above except the 10 quiet
+//     minutes still holds, the quiet is checked over RequestQuietWindow instead, and the runs are RequestRunGap
+//     apart, so the whole request ends in about 55 s.

+// POST /backup is reachable from inside the guest, and every successful run prunes the tier
+// (`--prune-backups keep-last=N` on a local tier; ep0's server-side keep-last 2 on the off-site tier). So
+// a compromised controller calling it in a loop pushed every pre-compromise whole-guest restore point out
+// within minutes — the threat `07` §8 row 10 counts the off-site tier as the answer to. The agent now
+// refuses a run that the schedule in `07` §6 would never ask for:
+//
+//   - a tier whose cadence is at most 24 h (the local tier): at most 3 successful runs in any rolling
+//     24 h. The schedule is one night run; a „Mentés most" press makes a LOCAL copy and, since R-899, the
+//     night still takes its own after it, which can land inside the same 24 h as the previous night (the
+//     window opens anywhere in [W+2h, W+6h)). So a normal day needs at most 3: two nights plus one press.
+//     A second press inside 24 h is refused — the margin is spent on the night, which must never be refused
+//     because of the household's presses.
+//   - a longer tier (the 7-day off-site tier): at most 1 successful run per max(cadence − 24 h, cadence/2)
+//     — 6 days for 7 days. The controller asks /backup/due first and runs only when the newest copy is older
+//     than the cadence, and the button never targets this tier (`07` §6, controller v0.301.0), so a
+//     legitimate run never comes sooner; 24 h of slack absorbs clock and archive-time differences.
+//
+// Only SUCCESSES count — a failed run prunes nothing and must stay retryable. The count survives an agent
+// restart: it reads the success history saved on disk (LastKnownBackupStore, the R-894 file) as well as
+// this process's own record. A refusal answers 429, is logged at WARN, is saved, and raises the operator

+//
+// MEASURED (felhom.eu audits/fixes-2026-10-21/P4-freeze/): on the minimum machine (8 GB host, guest 4096 MB) the
+// household's first uploads made Immich load its analysis models (+1.15 GB) on top of 8 apps' 1.75 GB; the guest hit
+// its 4096 MB limit with its swap capped at Proxmox's LXC default of 512 MB — and full. The kernel could then evict
+// only file pages: ~360 MB was left for the program code of ~25 containers, re-read from disk without end (150 000–
+// 600 000 refaults and ~1 GB of reads per 10 s; memory „full" pressure 92–95 %, load 155, the dashboard dead, 0 OOM
+// kills). Raising the cap to 4096 MB live ended it in under a minute (memory „full" 96 % → 1.7 %, dashboard back
+// 42 s later) while the uploads ran on. The host had 7.4 GB of swap free the whole time.
+//
+// The agent never set `swap` at all, so every guest had the 512 MB default. Now:
+//   - a new guest is created with swap = its memory (reconcile.bringup);
+//   - a RAM resize sets swap with the memory (handleGuestMemoryResize);
+//   - at agent start, every LXC in the felhom pool whose swap is below its memory is raised to it (this file).
+// Raising swap is a live cgroup change (memory.swap.max), no restart. It never lowers a swap someone set higher.

+// reboot_guest — the operator reboots a guest from the hub (D65 = A, operator ruling 2026-10-29 15:50; felhom.eu `04`
+// §6.1, `03`). No signature: a reboot destroys nothing (`03`, „healing … non-destructive by construction").
+//
+// WHY: a stuck Docker or a stuck network inside the box is out of reach of „Restart controller" — that restarts one
+// container. The reboot is the existing guest-reboot path (`pct reboot <vmid>`, the household's „A Felhom
+// újraindítása", the same exact sudo vector) — of THAT guest, never the host.
+//
+// THE GUARDS (each refuses with the reason in the result; nothing is called):
+//   - the guest is not one this agent provisioned, is not running, is locked, or its controller is parked;
+//   - a controller swap (update) is in flight;
+//   - a heavy operation holds the host-wide gate (a backup of any tier the agent runs, a restore test, an OS step),
+//     or jobBlocker finds one (an agent backup job, a drive or NAS job, an escrow ceremony, a vzdump of the guest);
+//   - the CONTROLLER says it is busy: a backup, a restore, an off-site run or an app update (its `ctl/busy` file,
+//     read over one exact `pct exec … cat` grant; controllerBusy below). Fails closed on any read error but „no file";
+//   - at most ONE reboot per hour per guest (the record below, persisted — it survives an agent restart);
+//   - the operator restart's brake: a reboot counts as a restart, and the brake's refusal refuses a reboot too.
+// The heavy-operation gate is HELD from the checks until the guest is up again, so no backup, restore test or OS
+// step of this agent can start in between. The guest-power watchdog and the controller supervisor leave the guest
+// alone while the reboot runs (rebootInFlight).
+//
+// AFTER: the result says when the guest was up and when the controller answered (both from the press). The record
+// `<guests>/<vmid>/operator-reboot.json` is written BEFORE the reboot, so the controller that starts after it finds
+// it: GET /guest/operator-reboot hands it to the household's dashboard („Felhom support restarted your box at …",
