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.

Wi-Fi auto-connect stays on, without a switch.

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

The MG4's display is given as 1920x720 (this project), 1280x480

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;

EVHardware's notes call the licence of EVProfile's upstream unresolved.
Checked: malys/EVProfile is MIT, forked from SliDeeN/MG4Control and last

(2026-08-05) and GPL v3 from 2.6.6 (2026-09-02), with the earlier

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

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.

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

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

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.

The car's key report, from the on-screen key log in 2.7.0:
android.intent.extra.hardkey.keycode = 287 (Integer),
android.intent.extra.hardkey.down (Boolean; one report on press, one on
release) and android.intent.extra.hardkey.longpress (Boolean). 2.7.0
only looked for short names like "keyCode", so it never found the code.
SteeringKeyReport now matches extras by the last part of their name,
case-insensitively, and is Android-free; its tests include the exact
double press logged on the car (releases 279 ms apart). Replayed in the
car's format on the emulator: double press opens the app, single and
long presses do not.

permission, setting, switch and strings): it did not show over the MG4

Steering wheel: a double press of the voice key (code 287) opens the
app. The floating button from 2.6.0 does not show over the MG4
launcher, so this is the way back into the app. The head unit reports
keys as the broadcast com.saic.keyevent.hardkey.report, whose extras
are not documented: the receiver tries the usual names (and an
embedded KeyEvent), and counts one press per report whichever way the
up/down field turns out to work; long presses never open the app. The
last 20 reports are listed raw on the Logs tab, so if the guess
misses, a photo of that list gives the real format. A switch in the
Upload tab turns it off. DoublePressDetector (500 ms window) has 5
tests; on the emulator, simulated double presses open the app and
single presses, other keys and long presses do not.
Scrolling: pages jumped back to the top on every 2 s refresh. A stack
trace on the emulator showed why: ViewPager2's RecyclerView lays the
pages out while measuring, at a provisional height, and
ScrollView.onLayout clamps the position to 0. StableScrollView keeps
the driver's position across layouts and is now the root of every
page; the scrolled Charging page stays put across refreshes.
Vehicle tab: all six value tiles, including both range estimates, sit
in one row at the top, so nothing needs scrolling at 1920x720.

The MG4's launcher does not list third-party apps, so the app could
only be opened by reinstalling it. Now a small round MG-red button
floats over the car's screens: tap opens the app, drag moves it (the
position is kept and clamped to the screen), and it hides while the
app itself is open. A switch in the Upload tab turns it off.
The always-on service owns the overlay, so the button is there from
boot. It needs the overlay permission (SYSTEM_ALERT_WINDOW), which the
car build has through the system UID; without it, or if the window
manager refuses, the button stays away and nothing crashes, and the
Upload tab offers the system permission screen.
Tested on an Android 9 AOSP emulator at the head unit's 1920x1080 /
160 dpi with the car APK (installs as UID 1000): button appears over
the home screen, tap opens the app, hidden while open, drag moves it
without opening the app, position survives a force-stop, the switch
works through the UI. FloatingButtonGeometry has 3 unit tests.

11 panels return data, energy matches 61 % x 50.8 kWh. SPECS.md lists
the missing signals and why.

- "Where the car was" fits the route again: in Grafana's fit view the
zoom value is the maximum zoom, and 6 held it at country level. Now
15 with 10 % padding. Checked by rendering the Live dashboard with a
simulated 10 km drive.
- Dashboard titles use "-" instead of an em dash: "MG4 - Live",
"MG4 - Consumption", "MG4 - Charging".
- SPECS.md: Grafana keeps its state in SQLite on its PVC, which is why
it runs as one replica with Recreate; high availability needs
PostgreSQL or MySQL first.

- The secrets template moves to k8s/secrets/, and the filled-in copy to
k8s/secrets/secrets.yaml (gitignored). `kubectl apply -f k8s/` does
not recurse, so neither the placeholder template nor the real secrets
can be applied by accident.
- The server image digest is pinned in server.yaml instead of through
kustomize's images override, which `-f` ignores (it would have pulled
a nonexistent :latest).
- README and kustomization.yaml say to use `-k`: plain `-f` never
creates the generated Grafana ConfigMaps.
- The IngressRoutes drop `tls: {}`, like the other routes on this
Traefik: TLS is configured on the websecure entrypoint.
Manifests validated both ways (14 resources rendered with kustomize,
11 as plain files — the difference is the Grafana ConfigMaps).

Both IngressRoutes (server and Grafana) now use traefik-internal, like
the rest of *.k8s.stinnesbeck.com, instead of the traefik-external
placeholder. README and SPECS updated.
