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.

/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.
Evidence regenerated: 3 change shapes across 106 fixtures, 5 byte-identical (both guest share
pages and the catch-all — the three that must not change).

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
the file and line in a second instead of hanging for 25 minutes.
MinAgent: 0.131.0 (unchanged). No hub release needed.

- addLanguageData: the v0.247.0 hide condition (switch only on non-Hungarian pages or with ?lang=) is
deleted; every template is converted, so the offer no longer leads to a half-English page.
- 89 layout parity fixtures re-captured; each equals its predecessor plus exactly one switch form after
the version span (checked byte-for-byte, 89 of 89). The 17 standalone fixtures are unchanged.
- TestLanguageSwitch_EndToEnd: a Hungarian household with no ?lang= sees the form (red-proofed by
restoring the condition: this test and 89 parity cases fail).
- CHANGELOG v0.250.0, README §18, CONTEXT.

marker; case completeness was checked with the coverage probe on a trial conversion.
