A car collected new sits at 0 km, and every km calculation in the app
quietly refused to work for it. ComputeDerived only filled NextServiceKm
when Km > 0, so a service record entered at 0 produced no next-due
distance at all — the date side worked, because it guards on IsZero(),
which is genuine absence rather than a number that happens to be low.
The same conflation had been copied outward from there. The reminder's
km signal wanted currentKm > 0 before it would count anything down, the
web badge and the service-life ring tested the odometer for truthiness,
formatKm printed an em dash for zero, and fuel and charging rejected a
0 km entry as "odometer (km) is required" — which is the first charge
of an EV on the driveway on delivery day. The phone app carried its own
copy of each. Editing such a car offered an empty odometer box, since
the forms only prefilled a reading above zero.
Everywhere the odometer is a measurement, absence is now tested as
absence: null in the clients, negative on the server, and the required
fields check that the box was filled rather than that the number cleared
zero. Fuel and charging validate Km < 0 instead, and their inputs drop
min="1". Completing a repeating km reminder rolls from the car's actual
reading in every case; the old fallback to the previous target existed
to keep an untracked car off a due date in the past, but CurrentKm +
RepeatKm is ahead of the car by construction, so it could not have
happened.
Left as it was: dueKm, repeatKm and the service intervals, where zero
really does encode "no trigger" and "use the default", and the liters
and kwh checks, since a zero fill is not a fill.
Maintenance is the exception. Its odometer is the one that is genuinely
optional, so zero there still has to mean "not recorded" and those three
sites keep the truthiness test, commented. Fixing that properly wants a
nullable field rather than an int, which is a schema change and its own
commit — the same shape of problem as the latency em dash in 3c4eba8.

Introduce a hand-rolled i18n layer across all three UIs, each reading its
text from per-language JSON files (English base + Polish + Danish). Nothing
in the converted screens hardcodes English any more.
- Web App (Vue): src/i18n/{en,pl,da}.json + index.js exposing t()/tSplit(),
reactive to the signed-in profile locale. Every view, component, form and
the status labels in lib/format.js go through t().
- API Server panel (Vue): src/i18n/ with its own localStorage-persisted
language (the panel has no user profile) and a header language picker.
Chrome, cards, login and API section titles translated; endpoint reference
descriptions intentionally kept in English. Rebuilt embedded dist.
- Phone App (Flutter): assets/i18n/ + lib/i18n.dart loaded at startup,
driven by AppSettings.locale. Nav, login, lock, dashboard, the full
Settings panel (incl. language picker) and format.dart status labels
translated; remaining detail screens fall back to English.
Language = the language half of the existing BCP-47 locale; the region half
still drives date/number/currency formatting. Missing keys fall back to
English, and plurals use Intl.PluralRules / Intl.plural so Polish gets the
correct one/few/many forms. Settings flags languages without a translation.
Tests updated to assert the localized (Polish) status wording; all pass.
See TRANSLATIONS.md for the format and how to add a language.

Four rounds of web-app features never reached the phone: fuel, maintenance,
document and reminder tracking; attachments; the currency setting and the
locale split; and technical check history. The README claimed full parity
throughout, so the gap was invisible. Catch the phone up, mirroring the web
components field for field.
Car detail grows the web app's tabs, in its order: technical checks,
maintenance, fuel (with the summary panel), documents and reminders, beside
the existing service and parts lists. The derived figures are the server's
and are rendered as "—" wherever it sent null — a window with a missed fill
has no consumption, and a plausible-looking 0.0 there would be a lie.
Attachments hang off service records, technical checks, workshop visits,
refills, documents and parts on identical terms, so one field and one apply
helper cover all six rather than being copied per form. As on the web, the
form only collects intent: the file endpoints address a record that must
already exist, so a create-with-file is two calls, and a failure on the
second reports as an attachment error because the metadata is committed.
Two bugs fixed on the way:
- _carPayload omitted technicalCheckIntervalDays. The API rewrites every
column from the body, so any car edit — including the one-tap odometer
update — silently zeroed the car's inspection interval.
- main() never called initializeDateFormatting, so month names ignored the
chosen language that the new Language picker exists to set.
Luxembourgish and Romansh are deliberately left off the language list: intl
ships no symbols for them and throws rather than falling back, which would
take out every date on screen. The browser has full ICU data and has no such
limit, so the web app can offer them. The server only validates a locale's
shape, so an unrenderable tag can still arrive from the web; format.dart
resolves through a supported-language check and falls back to en-US.
Labels for the language/region/currency lists are hand-kept because Dart has
no Intl.DisplayNames. The lists mirror validCurrencies in me.go.
file_picker is pinned to ^10: v8 compiles against android-34, which no longer
builds against the other plugins' compileSdk requirement of 36.
Adds the project's first test, covering the parts that fail silently rather
than loudly — null derived fields, the badge wording, and the locale guard.
The phone was not authorized over ADB, so the UI was not exercised on a
device: this is analyzer-, test- and build-clean, and every JSON field name
and route was cross-checked against models.go and server.go.
