tajniak81andClaude Opus 5 a203414ceb Phone App: the garage on the car's own screen
The one place a service badge is worth reading is the car it belongs to, and
that is the one place the app could not be opened: Android Auto runs no Flutter
engine, so a Flutter app is simply absent from the head unit. The same APK now
carries a second face — Car App Library templates the host draws itself, in
Kotlin under android/app/src/main/kotlin/com/drivervault/phoneapp/car/.

Two screens. The garage lists a car per row with its due badge on the second
line, worst first, because the host renders only the first handful of rows and
the car this list exists to mention is the overdue one rather than whichever was
added first. A tap opens what that car has coming: the odometer, the next
service, and the reminders the server holds for it — typed in and auto-derived
from documents and the service schedule alike, in the order it sorted them.

None of it is a second implementation of the app. VaultStore reads the session
the phone signed in with — the active server's base and token — out of
shared_preferences' own store, which both halves share, so a server switched on
the phone is the server the car reads from with nothing to keep in step; only
cc_active_base is new, because an untouched home entry carries no address of its
own, its base being kDefaultApiBase, a compile-time define nothing outside Dart
can see. CarStrings reads the same assets/i18n files by the same dot paths, so a
badge on the head unit is the string format.dart already puts on the phone, in
the language the account chose: of the 32 keys the car screens ask for, 28 are
keys a phone screen already used, and only carApp.* is theirs. CarFormat is
format.dart's twin — same date pattern and number grouping from the account's
settings, same worst-of-date-and-km service badge. A new test reads the Kotlin
for the keys it looks up and fails if any is missing from a language file, since
the analyzer's reach stops at the Dart.

It only reads. A screen you cannot type into is a poor place to edit a car and a
driver is a poor person to ask, so VaultApi has no write in it to reach for by
accident.

Three things the README now says out loud. The service is declared IOT, the
closest category the library defines for something that is a garage rather than
a map or a media player, which matters to a store submission and not to a
sideload. The app lock does not reach the head unit: the flag is in memory and
the credentials behind it in encrypted storage, neither readable from the car
service, and there is no fingerprint reader in a dashboard to satisfy it with.
And the home charger is not on there — the chargers endpoint relays its plugin's
payload verbatim with no shape to read, and the serial the control card is
driven by is never persisted, so the car would have nothing to name.

tajniak81andClaude Opus 5 12ec10a797 Phone App: more than one server, and a session for each
The web app can be pointed at two DriverVault stacks and switch between them in
a click. The phone had one address and one session: reaching a second garage
meant retyping the API base in Server settings and signing in again, losing the
first server's token on the way — the same act, undone, every time you switched
back.

So lib/servers.dart is the web's servers.js ported rather than reinvented, down
to the storage keys: cc_servers holds the list, cc_active_server the one being
read, cc_session_<id> the token minted by that server and no other. The two apps
describe the same thing the same way, and the upgrade path falls out of it —
cc_token, cc_user and cc_server_url are read once at boot and folded onto the
home entry, so the build carrying this signs nobody out.

Home is the address the build ships with (kDefaultApiBase, still overridable per
device from the login screen) and cannot be removed: it is what a dropped session
falls back to. Any other server is added by address, with /api appended if the
path is left off, because a server a phone can reach is internet-facing already.

The part worth reading twice is which session a rejection ends. ApiClient no
longer holds a base or a token — it pins the active server's id, base and token
at the moment a request goes out, so a 401 arriving after a switch clears the
session of the server that actually refused it rather than whichever one is
active by then. The fallback is the web's: a remote server timing out drops its
own token, the app returns to home while home is still signed in, and only when
nothing is left to fall back to does the login screen come back. Log out still
clears every server at once, since leaving the app means leaving all of them.

Switching rebuilds the shell, keyed on the active id, because record ids belong
to the server that issued them — a garage, a charging page and a settings panel
still holding the other server's rows would each have to be told to forget them
separately. The appearance prefs come across with the profile of whoever owns
the account on the server now active.

Where the picker lives is the one place the phone cannot copy the web. There is
no app rail here, so it became the first button in the Garage header, beside the
theme toggle and log out, which is that same cluster. It names the active server
once there is a choice and goes straight to adding the second when there isn't;
the eyebrow reads GARAGE · Work for the reason the rail names it — two garages
otherwise look identical. The login screen gets its own way in, because a remote
session can expire and land you there with that server still active, and a
picker reachable only from inside the app would leave nowhere to go.

One judgment call inside the sheet: saving a connected server at a new address
saves and stops, rather than falling through to the sign-in it now needs. The
token was minted by the PocketBase behind the old address and is dropped with
it, but the credentials to replace it were never asked for, so treating the save
as a login would report an empty password as the error.

The strings are copied out of Web App/web/src/i18n/ like the rest of the shared
wording. Two are not the web's: home reads "the address this app ships with"
rather than "served with this app", since the phone has no origin to be served
from, and sameOrigin has no meaning here at all and was dropped.

Biometric sign-in stays global. It was never per-server and replays its stored
credentials against whichever server is active; making it per-server is a change
of its own, and the login screen now names the server it is about to sign into.

Nothing changes on the API Server. On Android there is no origin to allow, so
the CORS list the web app has to satisfy to reach a second server doesn't enter
into it.

Verified: flutter analyze is clean and flutter test passes, 35 tests to 46. The
new ones cover the registry — a bare origin gaining its /api, a fresh install
knowing one unnamed server on the built-in address, the legacy keys landing on
home and being cleared, two servers holding their tokens apart, a rename keeping
a session where a move drops it, removing the active server falling back to a
home that is still signed in, home refusing to be removed, and a restart reading
the list, the active id and every session back.

Not verified: none of it has been run. There is no device or emulator on this
machine and no API Server to answer, so the picker, the add sheet, a real
connect, the 401 fallback and the shell rebuild on a switch exist only as code
the analyzer is happy with — the tests reach the registry, not a screen. No APK
was built. The legacy migration was exercised against mocked SharedPreferences,
which is not a phone that had the old build on it: that is the first thing to
check on a device, since the failure mode is a silent sign-out.
