An install over an app's kept drive folder (appdata/<app> non-empty) asks the household:
"use my kept data" (a load from the newest copy of THIS drive's install, own unit or
second-drive mirror, then the template's after_load) or "start fresh" (the folder is
renamed into <drive>/kept/<app>/<date>/ with the removed app's unit; nothing deleted).
The install API answers 409 kept_data_choice until one is chosen; DeployStack refuses
too. New page Megorzott adatok / Kept data (/kept-data): Load / Look / Delete (typed
confirmation, the only deletion of kept data). FileBrowser gets a read-only source.
The drive-full warning names the kept folders. <drive>/kept is protected and outside
every backup leg.
R-690: the removed-app restore (R-487) never found a unit on a DATA drive — it asked
GetStackComposePath (true for every catalog app) and restored nextcloud with no env.
Now isStackDeployed; pinned with a production-shaped provider.

A step whose ladder entry carries engine_conversion {service, engine, from, to}
converts the database: the old engine alone, the check (owners, roles,
extensions, per-table row counts), pg_dumpall validated by its completion line,
the volume emptied only after the undo copy's marker is validated again, the new
engine alone, the load with ON_ERROR_STOP, the check again + PG_VERSION. Any
failure goes to the existing undo; a restart during converting is undone.
A PostgreSQL major move without the mark is refused before anything moves.
The old datadir's copy is kept until a backup is proven after the conversion.

Found live on 9202 (night 2026-09-24 Part B): the sync rendered the ladder's newest
tested digest into a RUNNING app's compose, so the next restart would pull a new image
with no backup and no undo. stacks.CarryDigests keeps the running digest for an
installed app; a fresh install still takes the tested digest. Red-proofed.

Found live on 9202 (romm): .felhom.yml flows into the stack dir on every
catalog sync, so "the old .felhom.yml" saved at update time was already the
new one, and the serving old version was judged with the new probe.
New record applied-meta/.felhom.yml, written whenever a version is pinned
(deploy, adoption, pin advance) and put back by the undo, like
applied-compose.yml. The fixture now places the new file at sync time.

Found live on 9202: the periodic probe (current .felhom.yml, new port) flips
the app to unhealthy, and the update's health wait probed only 'running'
apps - so the undo's old probe was never asked and a serving old version was
judged "did not start". With the undo's override, an unhealthy app is probed
and the old check decides; never settled on container state.
New seam probeRunFn; the test drives the real wait loop and reproduces the
live message when the fix is switched off.

The guarded update gains a folder copy of the app's named volumes, taken
after the pull where the app stops anyway (decision 19, chosen by the
2026-09-23 bake-off). On a failed health check the box undoes: every copy
validated by its finished-marker first, volumes refilled, definition and pin
from the job's own pre-update copies, the old version checked with the OLD
.felhom.yml probe. It holds only if the undo fails, and the hold sentence
says so and what state the data is in. Bind-mounted folders are never
touched.
- R-637 built; R-638/R-640/R-641 do not arise with a folder copy; R-639
(pre-update copies incl. .felhom.yml kept until the undo is over).

Caught by the live proof on 9202, not by a test. The v0.262.0 guard fired exactly right and
answered HTTP 500: router.go maps remove errors by grepping the error TEXT for "not deployed" /
"still running" / "not found" / "protected", and the busy sentence contains none of them.
A 500 tells the UI something broke; this is "wait a moment". Now a typed *stacks.RemoveBusyError
matched with errors.As and answered 409, carrying both the Hungarian bytes and the bundle key.
Its test asserts the sentence contains none of the words the text mapping greps for, so the type is
load-bearing rather than decorative. Red-proof seen failing.

R-630 (P1): waitUpdateHealthy kept the probe inside `if hc != nil && len(hc.Checks) > 0`, and when
findProbeContainer returned "" its else set last="no probe container" and LOOPED - the settle path
sat in the outer else, unreachable. So verifying could only time out and failAndHold then stopped a
working app. Measured on paperless-ngx: three containers healthy, failed at +313.0s, front door 404
after. It now falls through to the same settle path with a WARN naming the candidates.
The probe target is decidable now: HealthCheckConfig.Container plus findProbeContainerMeta resolve
by exact stack name -> explicit container -> a UNIQUE prefix -> nothing with the candidates
returned. The old rule took the FIRST prefix match. A skipped stack records why instead of silence.
R-634 (half): RemoveStack refused on the !Deployed FLAG while the machine had containers, a compose
file and an app.yaml. It now asks whether anything EXISTS. The mechanism producing the bad record is
still not diagnosed and R-634 stays open for it.
R-633/R-626: RemoveStack consults UpdateGuards.Busy and IsUpdating and refuses with the app's own
sentence - the product already refused this clash for update and for restore. And because `down`
returning 0 is a request not a result, the project is watched for 25s afterwards, anything carrying
its label is removed by name with its labels logged, and the answer carries `verified`.
R-621: failAndHold writes compose logs --tail 400 into <stackdir>/hold-logs/<ts>/ BEFORE the down
that destroys them. Two existing tests pin the compose sequence and correctly caught the new step;
their expectations are updated with the reason that the ORDER is the assertion.
R-614: RemoveStack calls ClearUpdateState.
NOT in this release: R-625 (a held app still renders an Update button). Named, not half-done.

The controller self-updates daily at 04:30 by default, and after any hub report
once a floor sits above the box. That swap restarts the controller container.
The window proposed for automatic app updates is 02:30-05:00. It contains 04:30.
R-608 — a two-way lock, wired in main.go (stacks never imports selfupdate):
- stacks.Manager.AnyUpdating() -> Updater.SetAppUpdatingCheck, consulted in the
same three places as the existing backupRunning gate.
- Updater.IsUpdateRunning -> Manager.SetSelfUpdatingCheck; UpdatePreflight
refuses `self_updating`.
- MEASURED: the gap was narrower than assumed. The update's `backing-up` phase
already takes the backup single-flight, so that one phase was covered. The
other six were not, and `starting`/`verifying` are where data may have moved.
- The lock must NOT latch: a held app does not block the controller's own
updates, including the release that might fix the hold.
R-609 — the 409 carries `data.reason`, additively. transient (busy, updating,
deploying, migrating, self_updating) vs terminal (held, downgrade). Found while
writing the test: the router refuses a HELD app on its own line before the
preflight, so `held` would have been the one reason missing.

- stacks.CatalogOrder: the comparison gains a fourth answer (Ahead) and moves out of
web, so the badge and UpdatePreflight cannot drift apart.
- The badge: ahead reads „Naprakész"/"Up to date", tag-ok, with a title saying why.
- The refusal: UpdatePreflight returns `downgrade` (409), born as a bundle key; the

The composed-sentence-into-page-data class is now five instances and has its
own warning block in the README's i18n section, with the two things that make
a live probe lie: the felhom_lang cookie is ignored behind auth (so an English
probe of /backups returns Hungarian and reads as unfixed), and an apostrophe in
an English value is escaped so no assertion on the rendered page ever matches.

The 2026-09-20 English drill ended one screen short: the claim page was English
and its answers were Hungarian, so a household who mistyped the code from their
e-mail could not tell a typo from a dead code. Fourteen call sites carrying nine
messages now go through s.msg; the backup page's two protection warnings — which
are promises about whether the customer's files are safe — follow the same route.
Hungarian is byte-identical, proved structurally by the go-parity gate against the
frozen base capture and red-proofed on a single added full stop.
data["Title"] was DEAD (claim.html is standalone; .Title is layout.html's) and is
deleted rather than translated — a translated dead field is a permanent false
signal about where the page's title comes from.
Six existing copy-contract tests were kept, not weakened: each now resolves its key
through the real bundle, so it still convicts on a reworded Hungarian sentence.

The release fixed four Go-side leftovers. The walk that judged it on a box installed
from scratch that day found two more of the SAME SHAPE — a composed sentence handed
to a renderer as page data — on the claim page (R-596, P1) and the Backup page
(R-598). That shape now has three instances on file with R-573, which is worth naming
as a class rather than fixing one at a time.
Verdict recorded: not yet ready for an English-speaking tester.

R-589 the update badge, R-590 the data-folder backup sentence, R-573 the two channel
banners, R-572 two dead helpers. All four were built in Go, which is why neither the
template parity fixtures nor TestI18nEnglishPages could see them; slice 5's LIVE proof
is what found them.
R-590 is the one that matters most: it is a promise about the customer's files. It
said, in Hungarian and under an already-English folder label, that a drop-zone is
temporary and unbacked. The test now asserts the CONSEQUENCE in both languages — and
that the two languages do not produce the same string, which would mean the English
fell back.
R-572 is not what its row said. The row claimed a template renders "vasárnap" on an
English page; measured, NO template and no Go file called pruneLabel or
nextPruneLabel. They were dead func-map entries returning Hungarian, so they are
deleted rather than translated — translating dead code would add machinery with no
reader and a test pinning a fiction. Deletion is fail-loud and that was proven: a
template naming the removed function panics loadTemplates at startup.
Five red-proofs. One of them says something about the gate rather than the code: the
Go-parity gate does not measure localeFuncs keys against the base capture, so the
citation to TestLocaleFuncsHungarianBundleMatchesFuncMap is what carries them — the
test was extended to make that citation true.

The operator asked for the floor at the end of the translation work. Raised the same

declaration carries it. demo-felhom went 0.255.0 -> 0.257.0 by itself in under 12
seconds and THEN rendered the English tagline, which is the observable worth having:
the floor delivered the feature, not a version string.

README gains "Catalog copy in a second language" under §18: the format, the
field-by-field fallback, whole-list replacement vs key matching, the no-write-through
rule, the four templates that carry copy, and why an older controller is unaffected.
REPORT records the nine red-proofs — including the two that convicted a hollow TEST
rather than the code — and the live proof on both demo boxes, naming the method
(endpoint level, no browser on DooPlex) rather than implying a click-through.

The READ PATH for a second language in `.felhom.yml`. An `i18n: {en: …}` sibling
block inside the same file; `Metadata.For(lang)` merges it FIELD BY FIELD over the
Hungarian, so a missing or blank English field shows the Hungarian one and a
half-translated app is a legal, shippable state.
`For("hu")` is the parsed struct with `I18n` cleared and nothing else — measured
against all 53 real catalog files, copied into `internal/stacks/testdata/catalog/`.
Lists replace whole; every other list is matched by its own key, never by position.
`For` never writes through the receiver: the metadata is the stack manager's, shared
by concurrent requests, and an in-place merge would leak one household's language
into another household's page.
Pages reach catalog copy only through `LocalizeStacks`/`LocalizeStackPtr`/`MetaFor`,
and `TestNoDirectMetaCopyReadOnPages` keeps a named, reasoned allow-list of every
direct `.Meta.<copy>` read in `internal/web` so the NEXT page to read one fails the
suite instead of quietly rendering Hungarian to an English household.
Eight red-proofs. Two of them convicted a hollow TEST rather than the code: a struct
copy shares its slices' backing arrays, so the obvious DeepEqual mutation check
passed a deliberately broken merge; and a one-entry fixture cannot tell key matching
from position matching. Both rewritten, both then seen to fail.
MinAgent: 0.131.0 (unchanged). Older controllers are unaffected — `LoadMetadata`
uses non-strict `yaml.Unmarshal`, so a pre-0.257.0 box drops the whole block.

Found while trying to PROVE v0.256.0 on a live box: there was nothing to look
at. The box logs the Hungarian message only, the hub logs the Hungarian message
only, and the payload is inside TLS - so "did the box attach a second
sentence?" was unanswerable from either end. That is the fork in the diagnosis
when an English household reports a Hungarian mail.
[INFO] Event pushed: app_deployed (info) [+household(en)] — Alkalmazás ...
[INFO] Event pushed: app_deployed (info) [hu-only] — Alkalmazás ...
The sentence itself is not logged: it is the same sentence twice and one copy
is already on the line. Pinned in both languages.
A feature whose only failure mode is "the wrong language arrived" needs an
observable that says which branch was taken. Without one, every diagnosis is a
guess.

MinAgent: 0.131.0 (unchanged). Needs hub v0.118.0+, which shipped first and
tolerates a box that sends none of this - every box in the fleet is that box
until this release reaches it.
The hub writes a household's e-mails in their language now, but about a third
of those mails carry a sentence the BOX composed, naming a drive, an app or a
number. The hub cannot translate one. So the box sends it twice.
- message_customer on POST /api/v1/event, omitempty. A HUNGARIAN household
sends nothing extra at all, so its payload stays byte-for-byte what every box
sends today and the hub's fallback path keeps being the one production
exercises rather than a branch nobody takes.
- 19 producers render both sentences from ONE bundle key. `message` stays
Hungarian always: it is what the operator is mailed and what the hub logs.
- customer.language bootstraps a new box - stored choice, then config, then
Hungarian. The config value is NEVER written into settings.json: that would
record a choice the household never made.
The Hungarian did not move, measured twice: the wire golden from the slice-2
base commit, and the Go parity gate over all 19 new keys.
Three guards had to learn the change and one caught me: the test seam now
carries the new field; the R-329 severity register reported two dynamic sites
as no longer existing the moment they moved off PushEvent (the walk now checks
36 severity literals, up from 20); and TestConfigLanguageIsWiredInMain reads
main.go, because cmd/ is gitignored and ripgrep does not.
A mistake, named: the first pass dropped displayName from three producers,
which would have mailed customers "Alkalmazás telepítve: %!s(MISSING)". Caught
reading the diff; now pinned by a test that refuses %!/MISSING/%s/%d in either
language.

Two defects in v0.254.0's globe, both plain on a browser and neither catchable by anything
that existed — every test read the MARKUP, and the fault was in which CSS file the browser
fetched.
The shells requested /static/style.css with NO ?v=, while layout.html has carried one since
v0.166.0. A browser holding a copy from before v0.254.0 kept serving CSS with no .lang-globe
rules, so the globe came out as a bare unstyled <details> — a stray triangle and two plain
words at the edge of the window. It was FIVE shells, not the three named: both guest share
pages have the same fault for any CSS change, and their visitor is the likeliest of all to be
holding an old copy. And .Version was missing from three of those five data maps, which is
exactly how the next one would be forgotten — it is now filled at the one choke point every
shell renders through.
The globe also floated outside the card, pinned to the corner of the VIEWPORT, reading as part
of the browser rather than the page. It now sits inside the card, centred under the footer, with
the menu opening upward via the shared rule — so the dashboard and the shells cannot drift.
AND A THIRD, caught by a test that already existed: putting the version on the guest share pages
would have printed the controller build onto a page a stranger with a capability URL can open.
TestShareGuest_HeadersTilesNoAdminChrome refused it. Those two now take an opaque per-build tag
— same cache-busting, no disclosure. The fill is ONE function shared with the parity harness,
because a fixture rendered through a different data path is a picture of a page nobody serves,
which the previous release got wrong twice.
15 shell fixtures re-captured; 91 identical, every dashboard page among them.

0.253.0 -> 0.254.0 with min_agent 0.131.0 declared — the floor sits above the vouched golden,
so the declaration is what carries it (R-472), and the agent versions were checked first
because a floor is HELD for a box whose agent is below the requirement.
demo-felhom took it by itself in ~40 s. The box's own log is the observable that counts
("settle-gate: GO — at/above floor 0.254.0"), not the hub's claim, and the release's visible
change is there too: one globe on the sign-in page, zero of the old text links.
The two DOWN customers did not get it and will take it unattended when they return, from
0.115.0 and 0.245.0 — said plainly rather than left to be inferred from a green dashboard.

/recovery is in the AUTHENTICATED route table — its reader is the household, not a visitor. The
first draft of v0.254.0 gave it the anonymous form, which sets the felhom_lang cookie that
langFor deliberately ignores once there is a session: the button would have appeared to work
and done nothing. Found by the live probe on demo-hp reporting no globe on /recovery (it 302s
to /login without a session) and then reading the route table.
executeTemplateLang now branches on hasSession: household form with its session CSRF, or the
visitor form without. The parity harness and TestI18nDirectRenderPagesFollowLanguage carry the
same branch, so the fixture is the form the real page serves — the trap this release already
walked into once with the shells.
A per-session CSRF token cannot be a fixture value, so it is blanked on both sides of every
parity comparison, exactly as relative ages already were. What stays pinned is that the field is
THERE and WHICH form it sits in — the half that says whether the globe writes the household's
setting or the visitor's cookie.

The notes a background run SAVES — last night's backup line, the last error, the proof
result, the restore outcome — are written in the BOX's language at the moment they are
written. A household that switches sees the previous run's note in the old language until
the next run rewrites it: the operator's §16 option 1, stated rather than hidden.
EndRestoreOp no longer receives a Hungarian literal from anywhere.
The language switch is a globe. Two text links wrapped in the sidebar footer and asked the
reader to recognise "Magyar"/"English" as links; a globe is the one symbol every web user
already reads as "language", so nobody has to read Hungarian to escape Hungarian. It is
<details>/<summary> — a menu with no script, drawn inline because the icon sprite lives
only in layout.html and the visitor pages have their own shell.
Those visitor pages get the same globe, and a visitor's choice stays theirs: a display-only
felhom_lang cookie that langFor reads ONLY when there is no session. A signed-in household
can never inherit a language a previous visitor picked in the same browser. POST /lang is
CSRF-exempt for a narrow reason written at the exemption — its only achievable effect is the
language of the page the victim's own browser shows them — and safeBackPath refuses
//evil.example as well as https://, because "starts with /" alone is not the test. §16 taken:
a successful claim carries the cookie into the household's setting.
TWO PARITY EXCEPTIONS, MEASURED: 106 fixtures compared with a real diff — exactly two change
shapes (the dashboard footer, the globe in the shells) and 5 byte-identical, which are the
three pages that must not change.
I INTRODUCED A DEADLOCK AND THE SUITE CAUGHT IT BY HANGING. UpdateOffboxStatus holds the
settings write lock while running its callback; boxLang() wants the read lock; sync.RWMutex
is not reentrant. On a real box an off-site run would have hung forever HOLDING the settings
lock. Fixed by resolving the language before the callback, and guarded by a test that names
