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
URI to the verified copy in Downloads.

AGENTS.md still described upstream's EVABRPUploader (GitHub updates,
the old architecture and tabs). It is now the entry point for agents:
what the project is (app, Go server, k8s, EVHardware), the rules
(nothing touches the cluster, secrets, read-only telemetry, null is not
zero, fail closed, honesty), the facts confirmed on the car, the app's
structure and UI conventions, how to build, test, publish and install,
and which document holds what. SPECS.md stays the journal.
The Android 9 test emulator, so far a file under the ignored build/,
is now reproducible: nix run .#car-emulator creates an AVD at
1920x720/160 dpi with the AOSP image that shares the car's platform key
and starts it on port 5560. Checked from scratch: the car build
installs as the system user.

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 Overview panel's title came from upstream, where it also showed
pack energy and temperatures. The MG4 publishes none of those, so the
panel only holds the odometer and the climate setpoint; its title now

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:
WifiAutoConnect, its call on the service tick, the preference key, and
the ACCESS_WIFI_STATE / CHANGE_WIFI_STATE permissions.

- Settings: the Wi-Fi and saved-networks cards are gone, and the rest
sits in three columns (display and steering wheel | battery |
charging price and app) instead of one tall column. The background
Wi-Fi auto-connect stays on, without a switch.
- Logs: only the upload log. The steering-key reports, the car-colour
probe and the screen line answered their questions and are removed,
with their code (CarColorProbe, the key-report log) and strings.
- README lists the current tabs.

standing included, from the same samples as the other averages.
- The top bar is one compact line (title and subtitle side by side).
Version, update check and About moved from it to an App card on the
Settings tab.
- The Overview no longer scrolls in the car's window: checked on the
emulator at 1778x640, the layout height the car reports, after
trimming the page's padding and the tyre card's height.

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.

Read on the car with 2.16.2: panel 1920x720 px at 160 dpi, app window
1778x720 px (the car's own sidebar takes the rest), so EVProfile's
1280x480 (1920x720 at 240 dpi, in dp) does not apply here. The colour
probe found only ro.build.mtk2712.vehicle_type = AS28: the paint colour
is not among the system properties. FIRMWARE.md, mise.toml and
SPECS.md updated.

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.

EVHardware's notes call the licence of EVProfile's upstream unresolved.
Checked: malys/EVProfile is MIT, forked from SliDeeN/MG4Control and last
merged from it on 2026-08-02. MG4Control is MIT up to 2.6.5
(2026-08-05) and GPL v3 from 2.6.6 (2026-09-02), with the earlier
versions staying MIT, so the code EVProfile took is from the MIT
period. Recorded with links; not an audit of every EVHardware line.

Leon Kernan's ABRP_Uploader has carried the MIT Licence since
2026-07-29 (lkernan/ABRP_Uploader commit 75d8f2bc), so the inherited
"no licence upstream, status unresolved" notes no longer hold.
- LICENSE: MIT, now naming every copyright holder in the fork chain
(Leon Kernan, EVABRPUploader contributors, FatihsMG4 contributors,
Nils Stinnesbeck).
- LICENSE.md: rewritten. The repository is MIT except EVHardware/,
which is PolyForm Noncommercial 1.0.0; the app links it into the APK,
so the built app is non-commercial. EVHardware's own caveat about
EVProfile stays with it.
- README, AGENTS.md, CONTRIBUTING.md and SPECS.md say the same.

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 read-only token for Grafana needed a manual influx command and a
Secret. InfluxDB generates every token but the admin one and ignores a
chosen value (tested on 2.7.12), so it cannot be preset in a Secret.
Instead an init container in the Grafana pod creates it at every start
with the admin token, deletes the one from the previous start, and
writes only the read-only token to a memory-backed volume; the
provisioned datasource reads it with $__file{/run/influx/token}. The
Grafana process never sees the admin token. The grafana-influx Secret
is gone from the template and the README.
Tested in podman: InfluxDB 2.7.12, the script run twice as the Grafana
user (the old token is replaced, not piled up), and Grafana 13.2.3
reporting the datasource healthy with the file-based token.

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

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.
