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.

DriverVault
A car control & service-tracking system (originally "Car Control Project").
Built incrementally — starting with a car maintenance tracker (modeled on
Car Service.xlsx) and growing toward live integration with the car via a
cellular ESP32 device and third-party services (Toyota Connected, EV chargers).
Architecture
All clients communicate with the database only through the API Server — nothing talks to PocketBase directly.

The Web and Phone apps are at feature parity.
Features
- Maintenance tracking — cars, service history (date/odometer + which parts were changed), and a per-car parts catalog, with next-due date/km status from the spreadsheet formulas.
- Technical checks — the mandatory roadworthiness inspections (przegląd techniczny / MOT / TÜV): result, cost, station and the certificate's valid-until, which overrides the car's interval and drives the next-due date.
- Maintenance log — workshop visits and repairs outside the routine schedule: type/status, workshop, parts used, labour + parts cost, invoice, warranty-until.
- Fuel tracking — refills with derived efficiency (average / best / worst consumption, cost per km, price per litre). Consumption is measured between full tanks, so partial fills roll into the next full one.
- Documents — insurance, registration, road tax and the rest, each with a server-computed renewal/expiry state.
- Reminders — date- and/or odometer-triggered, one-off or recurring, plus read-only reminders the server derives from documents and service records.
- Attachments — one optional file (PDF or image) per service record, technical check, maintenance entry, refill, document and part; fetched back through the API Server, never a public URL.
- Accounts — PocketBase-token login, profile + appearance preferences (theme/locale/date format/currency/font), avatar, email verification, data export/import, and an account-deletion state machine.
- Organizations & roles — multi-tenant
user/admin/superadminroles; admins manage users within their own organization, superadmins span all. Any user without an organization can create one and becomes its admin. - Per-user ownership & sharing — each car has an owner and can be shared with other users as read or write; the UI mirrors the server's access checks.
- Integrations — per-user connectors under a superadmin → org-admin → user cascade. Built-in today: Toyota Connected (read-only vehicle data) and the Anker Solix V1 EV charger.
- Cars from the manufacturer's own service — import a car straight off a connected account (MyToyota today), choosing what to pull in, and read everything that service knows about it from a dedicated first tab on the car. Generic over providers: the next manufacturer is one adapter in the API Server.
- EV charging control — for Anker Solix chargers the API Server runs an OCPP 1.6J Central System; in own/proxy mode the charger dials back in and the owner can start/stop and set limits from the Charging screen.
- Translated UI — the interface reads its text from per-language files (English, Polish, Danish today), with English as the fallback for any untranslated string. See TRANSLATIONS.md.
- Phone biometric login & app lock — fingerprint / face sign-in with an app-lock that requires an unlock on relaunch. See the Phone App README.
Auth model
All apps share one auth model: authentication is PocketBase's own.
POST /api/auth/login is proxied to the PocketBase users collection and the
client keeps the token PocketBase minted — the API Server does not issue its
own JWT. Every protected request carries Authorization: <token> (both
Bearer <token> and a raw token are accepted) and the server re-resolves it
against PocketBase on each call, so a role change or a deletion takes effect
immediately. Tokens are stateless, so there is no per-device session list;
changing an account's password rotates its token key and invalidates every token
already issued. Access to cars/records is gated by per-user ownership and shares;
user management requires the admin or superadmin role. Creating an organization
is the one management action open to a plain user — it promotes them to admin of
the organization they just created.
Domain (from Car Service.xlsx)
- Cars — one per vehicle (was: one spreadsheet sheet), with spec fields (engine / transmission / differential oil, brake fluid, coolant, VIN, fuel type, build / first-registration dates, …) and configurable service intervals.
- Service records — date + odometer per service, plus which parts were changed (oil & oil filter, engine air filter, cabin air filter).
- Parts — per-car catalog of part numbers.
Key spreadsheet formulas, reproduced by the API Server on read:
Next Service Date = service date + serviceIntervalDays (default 365; Excel: =A+365)
Next Service Km = service km + serviceIntervalKm (default 15 000; Excel: =B+15000)
Intervals are configurable per car.
Getting started
Bring up the stack in this order — each app's README has the details:
- API Server — configure
.env, runsetup-pocketbase.mjs, start the server. This must be running for either app. - Web App —
npm install && npm run dev(proxies/apito the server). - Phone App —
flutter build apk/flutter runwith--dart-define=API_BASE=http://<server-ip>:8080/api.
Or skip all of that and bring the whole stack up with Docker, which runs the schema setup itself — see Docker (PocketBase + API Server + Web App as three containers) or Docker-AIO (all three in a single image).
