The badge said "D" for every gear that was not P, so N and R read as D.
EVHardware now passes on the raw gear code; the badge shows P for 1,
no letter for codes not yet mapped, "—" when unread. The Logs tab lists
each change of the code with time and speed, to match R, N and D on
the car. Emulator only.

A third Overview style beside Tiles and Dashboard: rings for battery,
power (zero at the top, regeneration anticlockwise in green) with the
speed and gear inside, and 5-minute usage with a tick for the average
since start; below, the power of the last two minutes, the clock,
climate and odometer. Unread values light nothing and show "—"; the
trace leaves gaps (PowerTrace, unit-tested). Emulator only.

The car refuses the silent session for a non-system app; the fallback
installer screen could not read our FileProvider URI because grants
from the system user are refused. The car build now hands it a file

Settings -> App -> "Install from USB stick" (car build only). It looks
in the top folder of every mounted volume (found from the app's own
folder on it, since the head unit has no file picker) for
NilsMG4-unstable-<version>.apk, takes the newest one newer than the
installed version, checks it against its .sha256 sidecar and the
package name, and installs it with the same PackageInstaller session
as the over-the-air update. The stable build gets a stub and no button.
Tested on the emulator: 2.18.0 installed a 2.18.1 from the storage's
top folder without a confirmation, as the system user, so the OTA
install step should not need one either.

- The "Your private connection" card is gone; its text was out of date
(the ABRP credentials are no longer on the server).
- Import from file moved next to Save and Test, in one row.
- The installation ID is shown as text instead of an editable field:
it is derived from the head unit, and changing it by hand only risked
splitting the history. A config file can still carry an older one
over, as before.
- The page fits the car's 1778x640 window without scrolling (checked
on the emulator), and the subtitle no longer says the server passes
data on to ABRP.

Upstream kept the head unit on the driver's phone hotspot by re-joining
a saved network every few minutes. This car's head unit has its own
connection and the Wi-Fi is not used, so the feature goes entirely:

the ACCESS_WIFI_STATE / CHANGE_WIFI_STATE permissions.

charging price and app) instead of one tall column. The background
Wi-Fi auto-connect stays on, without a switch.

Version, update check and About moved from it to an App card on the

Back to drop-downs for upload frequency, tyre pressure unit and accent
colour, as Material exposed dropdown menus instead of Spinners. A
Spinner's list is a focusable window of its own without the
full-screen flags, so the car showed its bars while it was open; an
exposed dropdown's list leaves the focus with the activity, so the app
stays full screen. Styled like the other input fields, with full-height
rows. Replaces the buttons of 2.16.3.

Opening a drop-down or a dialog brought the car's bars back until it
closed: each is a window of its own, and the system shows the bars when
a window without the full-screen flags takes focus.
- The drop-downs (upload frequency, tyre pressure unit, accent colour)
are now single-choice buttons on the page: no extra window, one tap
instead of two, full touch targets, the choice in the accent colour.
- Dialogs (About, update, pairing, phone settings, trip reset, date
picker) are shown unfocusable, given the activity's full-screen
flags, and only then allowed focus. None of them takes typing, which
an unfocusable window would block.

The MG4's display is given as 1920x720 (this project), 1280x480
(EVProfile's README) and a 1778x720 app window (upstream). 1280x480 is
exactly 1920x720 px at 240 dpi expressed in dp, so the figures may
describe one panel at different densities, which this platform lets be
changed per app.
The Logs tab's new SCREEN line shows the panel's pixels and density and
the app window in px and dp, to settle it from the car. FIRMWARE.md
lists the three figures and what the emulator shows at 240 dpi;
mise.toml, README and SPECS.md no longer state 160 dpi as fact for the
car.

The Overview read the car every 2 s, on the main thread. It now reads
every 0.5 s on a background thread (one reader; a read still running
makes the next tick skip rather than queue) and shows the values on the
main thread. The consumption and charging trackers stay on the 2-second
tick with the newest reading: they integrate over time, and the
charging tracker writes its session to storage on every sample.

The car updates itself again, from this fork's own releases, while the
repository stays private:
- publish-car (flake) creates the pre-release car-<version> on the
forge and attaches the APK and its .sha256. It needs a forge token
that may write releases, from ~/.config/nilsmg4/forge-token or
$FORGE_TOKEN; it is sent in a header and never printed.
- The server relays releases and attachments (/v1/app/releases,
/v1/app/assets/...), read with a read-only FORGE_TOKEN from its
Secret, GitHub-shaped with download URLs back at itself. Redirects
away from the forge are not followed; off (404) without a token.
- The app asks its server with its own paired token, allows exactly
the server's host, downloads the APK itself instead of through the
DownloadManager (so the token stays in the app), verifies SHA-256 and
package name, and tries a PackageInstaller session (it may install
silently as the system user) before falling back to Downloads.
OTA.md is rewritten for this flow; the k8s and server READMEs explain
the new token.

Unsent live samples were kept in memory only, so a reboot or a killed
process during a dead spot lost them. The queue is now saved to
files/telemetry_queue.json with AtomicFile, at most every 5 minutes and
only after a change (the flash is not written every 15 s), and at once
when the service stops; it is restored, oldest first and within the
2000-sample cap, when the service starts. A damaged file restores
nothing rather than failing. Tested on the emulator across a reboot.

The Overview tiles' values (and the notes under them) are right-aligned
and use tabular figures, so a value going from 9 to 10 to 100 grows to
the left instead of shifting the whole text, and digits no longer
change width as they tick. The labels stay left; tyre pressures stay
centred but use tabular figures too.

The accent is selectable in Settings → Display: Dynamic Red (default),
Volcano Orange, Holborn Blue, Racing Green, Camden Grey, Monument
Silver, Arctic White and Black Pearl. White, silver and black cannot be
an accent on the black screen as they are, so they become light greys
and a pearl blue-grey.
The accent palette is now theme attributes (attrs_accent.xml) with one
overlay per paint (accents.xml), applied before the activity inflates;
layouts, colour lists, drawables and the views that draw in code use
them, including the red tints that were hard-coded. A change recreates
the activity on the same page. Android 9 crashes on gradients with
theme colours, so the battery card is built from layers.
Logs → "Look for the car colour" lists the head unit's system
properties that mention colour, paint or car model, to find out whether
the paint colour can be read from the car.

The ABRP credentials are long to type on the car. "Enter on phone"
(Live data tab, and Settings next to the charging price) shows a QR
code; it opens a form on the server where the phone sends the ABRP API
key and user token, charging price and usable capacity, confirmed with
the approval password. The car polls with its own token and collects
the values once, then saves them through the same checks as the fields
on screen.
Same device-flow shape as pairing. The server keeps the values in memory
only, at most ten minutes, hands them out once with no-store, and never
logs them or puts them back into the page; a paired token only reaches
its own installation's request. Pairing's QR dialog is now shared
(PhoneQrDialog), and the phone pages share one stylesheet.
The config file also takes charging_price and usable_kwh.

The car sends live data to ABRP itself, and the car and the server go
over the same mobile connection: when the car cannot reach ABRP, it
cannot reach the server either, so the server's fallback bought
nothing. The forwarder, its ABRP_* settings and abrpSentUtc are gone;
the server only stores. The app stops sending abrpSentUtc (the server
ignores unknown fields, so 2.11.0 keeps working) and its texts no longer
promise a server fallback.

ABRP keeps getting live data while the car server is down: with an ABRP
API key and user token set in the app (Live data tab, or abrp_api_key /
abrp_token in the config file), the car sends the newest sample to ABRP
itself at every upload. It tells the server the newest sample ABRP took
(abrpSentUtc), and the server forwards only newer ones, so ABRP gets
each sample once. Without credentials in the app the server forwards
everything, as before. The credentials sit in encrypted storage, go in
the request body, and neither they nor ABRP's answer are logged.
Settings are grouped by what they are for:
- Live data (was Upload): on/off, ABRP credentials, upload frequency.
- Settings (replaces the Wi-Fi tab): full screen and voice key,
usable capacity and manual SoH (were on Consumption), charging price
(was on Charging), Wi-Fi.
Charging and Live data get icons of their own.

Net regeneration over the window (or the trip) used to hide both

"Range since start" replaces the range at current power: remaining
energy over the consumption since the car was switched on, standing
with the climate on included. A trip starts again after 10 minutes
without samples (the car was off) or when charging.
The kWh/100 km for both estimates moved out of the range tiles into
two cards of their own, directly below them; the overview still fits
the full-screen 1920x720 display without scrolling.

Telemetry no longer loses queued batches. The server drops a bad value,
or a sample without a plausible time, instead of rejecting the batch,
and answers 200 with what it dropped. The app sends only values inside
the server's ranges (speed as a magnitude, so reversing is fine) and no
samples before the head unit's clock is set.
Server:
- Pairing hands out and accepts a token only after the device is saved;
a failed save leaves the request pending.
- A paired token serves only the installation id it was paired with
(403 otherwise); the shared INGEST_TOKEN still serves any.
- Wrong-password lockouts and open pairing requests are limited per
client address (last X-Forwarded-For entry), so a stranger cannot
lock the owner out; a car starting again replaces its own request.
- ABRP forwarding skips samples stamped ahead of the server's clock,
which used to stop it until a restart.
App:
- Settings written to plaintext during a keystore failure move back
into encrypted storage; the stored installation id wins.
- The installation id is derived from ANDROID_ID on first start, so a
reinstall finds its history; a stored or imported id still wins.
- The scanned config file is deleted after import (it holds the token).
- GPS stops while live telemetry is off or the server unconfigured, and
pauses while parked and idle, keeping the fix the car parked with.
- Range estimates use the monotonic clock.
- One HTTP helper (ServerHttp) for telemetry, sync and pairing.
- Last Turkish strings translated; mise logs shows the NilsMG4 tags.
Grafana reads InfluxDB with its own read-only token (new grafana-influx
Secret, created by hand as described in k8s/README.md).

On the MG4 the immersive flags hid SAIC's bars but left a black band

The unstable flavor appended upstream's CI build number as a fourth
part (2.8.0.0-unstable; always .0 without CI). Versions are now the
plain three-part defaultConfig version: 2.8.1-unstable, and build-car
names the APK NilsMG4-unstable-2.8.1.apk. The version code keeps the
x100000 factor (2.8.1 = 6700000): without it the code would fall below
the 6600000 already installed, and the installer refuses downgrades.

Immersive full screen while the app is in front: the system's top and
bottom bars are hidden, and a swipe from the edge shows them briefly.
Re-applied whenever the window regains focus. A "Full screen" switch in
the Upload tab (default on) turns it off.
On the Android 9 emulator the bars are hidden (system UI flags 0x1706),
stay hidden after leaving and returning, and the switch toggles them
through the UI. Whether SAIC's own bars on the MG4 obey the flags is
only known on the car; if they do not, nothing changes.
