mg4-server:2.0.0 is on git.stinnesbeck.com and pulls anonymously, so
the Deployment no longer references a registry pull secret. The image
is pinned by digest (sha256:6feea777…) so a re-pushed tag cannot
change what the cluster runs. README and secrets template updated.

ev_cyan becomes a light red (#FF9A9E, for values and secondary
highlights, readable on black) and ev_cyan_deep a deep red (#3A1215,
version badge). Turquoise hardcoded in the battery card, switch track,
input panel, car outline, background glow and charging-graph grid is
replaced with matching red tones, as are two gold leftovers (tab
outline, second background glow). The mint "OK" status colour and the
amber charging curve are unchanged.

- k8s/grafana.yaml: Grafana 13.2.3 with a 1Gi PVC, sign-up and
anonymous access off. The InfluxDB datasource (URL and token from the
environment) and three dashboards — Live, Consumption, Charging — are
provisioned from k8s/grafana/ via kustomize-generated ConfigMaps.
- server.yaml for the Go server (port 8080, UID 65532, smaller limits),
image tag 2.0.0. The NetworkPolicy now admits Grafana to InfluxDB.
- ingress.yaml: IngressRoutes for car.stinnesbeck.com and Grafana
(placeholder host car-grafana.stinnesbeck.com) with tls: {}, using
Traefik's default certificate; the cert-manager Certificate is gone.
- secrets.example.yaml: drops the dashboard secrets, adds grafana-admin.
- AGENTS.md loses its Next.js block; SPECS.md describes the new setup.
The removal of web/ (the Next.js app) and of the stale .next/ cache
upstream had committed already landed in 51e6f6f, which was staged
together with the Go server by mistake.
Checked end to end in podman (Go server + InfluxDB 2.7.12 + Grafana
13.2.3): all 25 dashboard queries return the expected data, and the
dashboards were rendered with headless Chromium. Manifests validated
offline with kustomize and kubeconform. Nothing applied to a cluster.

Same endpoints, request formats, validation rules and InfluxDB layout as
the Next.js server, so the car needs no change: POST /v1/telemetry,
PUT /v1/consumption/daily, PUT /v1/charging-sessions/{id}, GET
/v1/consumption/history/{id}, GET /v1/health. The dashboard, login and
the /v1/history reads are gone; Grafana takes over the dashboards.
- Go 1.26 standard library (net/http routing, log/slog) plus the
official InfluxDB 2 client. Fails closed at startup on a missing
InfluxDB setting or an ingest token under 24 characters.
- ABRP forwarder ported: newest fresh sample, rate limited, never
queued, credentials only in the form body.
- 22 tests: validation, aggregation, forwarding, config, and the
handlers through a fake store. govulncheck clean (x/net 0.60.0,
toolchain go1.26.9).
- Image: static binary on distroless, about 11 MB, UID 65532, port
8080; the build runs vet and the tests.
- Dev shell: Go, gopls and govulncheck instead of Node.

Dashboard: every label, empty state, chart legend and the login page
are English; numbers and dates use en-GB (24-hour clock, day-month
dates), money is EUR, percentages read 80% instead of %80, durations
"2 h 05 min". html lang is en. Server version 1.1.2; manifests pin it.
Car app: the charging tab's price suffix, validation message and total
cost use € instead of ₺.
Checked by rendering all three pages from the 1.1.2 image against
InfluxDB 2.7.12 in podman.

ev_accent is now #E0424C, the red of the launcher icon (about 4.6:1 on
the black background, enough for accent-coloured text; the darker MG
brand red is about 3:1). ev_on_accent and ev_gold_surface follow with a
dark red tint; the gold hardcoded in two drawables and the consumption
period buttons is replaced too. AGENTS.md's visual direction updated.

- New Server tab: server URL, ingest token and installation id, with
Save, Test connection (health, then a read-only token check) and the
config-file import that upstream removed (app folder / USB stick first,
document picker as fallback). Settings are kept encrypted and read on
every use, so the service picks up a change without a restart. Each
installation generates its own id; the inherited upstream UUID and
the baked-in CONSUMPTION_API_* build fields are gone.
- Live telemetry restored from before ea8032a (TelemetryPayload,
UploadCadence, UploadSettings, GPS) and sent in batches to
POST /v1/telemetry instead of ABRP; the server forwards to ABRP. Adds
ext_temp, voltage and current. Unsent samples queue in memory (about
8 h) while offline.
- Upload tab: the live-telemetry switch and cadence controls work again;
the dead service and autostart switches are removed.
- Manifest: location permissions and foreground service types.
- Unit tests compile again: 114 (stable) / 136 (unstable) pass. Tests
for the deleted AbrpApi and HeadUnitWeather removed; new tests for
ServerConfig and TelemetryQueue. Lint passes.
Not yet tried on the car.

Namespace, InfluxDB 2.7.12 StatefulSet with PVC and a NetworkPolicy
that admits only the server, the server Deployment (non-root, read-only
root filesystem), a cert-manager Certificate from letsencrypt-prod and a
Traefik IngressRoute. Secrets are a template only. Nothing is applied;
k8s/README.md has the steps. Server version bumped to 1.1.0.
Validated offline with kustomize and kubeconform (including the
cert-manager and Traefik CRD schemas). The InfluxDB container was tested
locally as UID 1000 with no capabilities.

- MongoDB replaced by InfluxDB 2 (one bucket, installationId tag).
Consumption is stored per chunk at its recordedAt and summed on read,
so a chunk the car re-sends from its cache overwrites itself instead
of being counted twice ($inc did count it twice). Lifetime is a
running total derived on read.
- POST /v1/telemetry takes batches of samples in ABRP's tlm fields; every
field is bounded, unknown fields are dropped, unread signals stay absent.
- After a successful write the newest fresh sample is forwarded to ABRP
with ABRP_API_KEY / ABRP_USER_TOKEN from the server environment; rate
limited, never queued. The car no longer needs ABRP credentials.
- Self-hosting: standalone output, Dockerfile (tests run in the build,
runs as UID 10001), .env.example and README for the new setup.
- Dev shell gains Node 22 and InfluxDB 2.
Verified locally against InfluxDB 2.7.12: all endpoints, retry
idempotency, and the dashboard pages. Unit tests: 17 pass.

Without adb there was no way to see why vehicle values stay blank:
refreshVehicle() swallowed every exception. The Logs tab now shows the
package, version, UID (and whether it is the system UID), signer
SHA-256, firmware, car permission grants, the last snapshot and read
error, and the newest 200 entries of the vehicle library's AppLogger.

- applicationId com.evsuite.abrp -> com.stinnesbeck.nilsmg4 (the car
build is .unstable); the Java namespace is unchanged. Installs next to
upstream's app rather than over it.
- APK names NilsMG4-*.apk, debug builds included; build-car follows.
- OTA install-result action, cache/download names, User-Agent and log
tags follow the new name.
- About credits fatihdonmezdev / FatihsMG4.
- SPECS.md journals what changed and what is still to do, starting
with pointing the About link and QR code at git.stinnesbeck.com/nils/mg4.

The updater stays in place, but its releases URL now uses the .invalid
TLD (RFC 2606), so checks fail instead of offering upstream's Turkish
builds over this one. Swap in a fork's releases API to re-enable it.

The MG4 head unit's platform certificate (c8a2e9bc…192ab8, per
tools/README.md) is the public AOSP test key. build-car fetches that key
into the gitignored tools/ directory from a pinned android-9.0.0_r1 tag,
builds assembleUnstableDebug, zipaligns and signs it, and refuses to
finish unless both the key's certificate and the resulting signer match
the expected SHA-256. Output lands in build/car/ with a .sha256 sidecar.

lifetime is now optional in DailyConsumption — guard all .lifetime
accesses. The Ömür boyu card uses the derived total (sum of days).
Co-Authored-By: Claude <noreply@anthropic.com>
validateConsumption required lifetime, but the app stopped sending it
(backend now derives it). asObject(undefined) threw 'body is required',
rejecting every chunk. Now lifetime is optional in both the validator
and the DailyConsumption type.
Co-Authored-By: Claude <noreply@anthropic.com>
- backend daily PUT: no longer $set lifetime (app's local counter is unreliable after APK wipe)
- backend history GET: derives lifetime as sum of all days' totals, returns it at response level
- app: stops sending lifetime in chunks; reads it from history response
- app: refresh button on consumption pane + 'Şimdi yükle' on log pane (manual cache flush)

MongoDB error: 'Updating the path day would create a conflict at day'.
On insert, $inc treats a missing field as 0, so no seed needed.

- HTML <input type=date> in a GET form, zero client JS (same server-component model)
- selected day detail card with tiles + rows above the period summary

The published APK carries the Vercel origin and the write-only ingest token.
Verified against the signed artifact: the origin and token are present, and no
MongoDB URI, host or password appears anywhere in the dex.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A lone password field is usually ignored: managers key a saved entry on
(origin, username), and with no username there is nothing to key on. There is
only ever one account here, so the hidden field carries a fixed value and the
server never reads it.

Sign-out answered GET behind a <Link>, and Next prefetches links that are in the
viewport. The button sits in every page header, so the browser called it as soon
as a page rendered and cleared the session cookie before the reader had clicked
anything. The first page loaded; the next navigation landed back on the password
screen, which read as the session not persisting.
It is a POST form now, and the route answers POST only — a prefetch of it gets
405 and changes nothing. The rule this broke is the general one: an endpoint
with a side effect must be unreachable by a prefetch, a crawler, or a browser
preloading what it thinks you will click.
Both session cookies are now set on the returned response rather than through
the cookies() store, which a freshly constructed redirect does not reliably
carry.

A file named .env.vercel or .env.production would have been committed by the
old two-line list, which is exactly the file someone reaches for when they need
somewhere to paste real credentials.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The standalone service in server/ was never deployed anywhere, and keeping it
alongside a Vercel app would mean maintaining two implementations of the same
validation rules. It is deleted; web/ is the only ingest path now. Its routes
live at /v1/... rather than under /api, so the Android client's URL building is
unchanged and CONSUMPTION_API_URL stays a bare origin.
Credentials are split in two. INGEST_TOKEN is baked into the published APK and
must be assumed extractable — anyone can unzip an APK and read its strings — so
it opens the PUT endpoints and nothing else. Reading the history needs the
dashboard password, which is never compiled into anything and reaches the
browser as an HMAC-signed httpOnly cookie. The MongoDB URI stays a server-side
environment variable; the car has never held one and still does not.
The dashboard is a phone-shaped reader for the same data: totals for energy
taken and paid, a daily energy chart, an efficiency trend, and every DC session
with its power/SOC curve. It reuses the head unit's OLED palette so the two read
as one app. Every page is a server component and the charts are hand-rolled SVG,
so the whole thing renders without shipping client JavaScript.
MongoClient is cached on globalThis: a fresh client per request means a fresh
pool per request, and Atlas starts refusing connections long before the traffic
would justify it. Index creation moved to the first write of each warm lambda,
since a serverless deployment has no boot step to hang it on.

The charging session meter used the head unit's wall clock, which jumps when it
picks up GPS or NTP time. One forward jump mid-charge invented both kWh and
hours. The consumption counters already integrate on elapsedRealtime for exactly
this reason; the session meter now does too, and keeps wall-clock values only as
the start and end stamps a reader needs to place a session on a timeline.
Intervals longer than five minutes are no longer bridged. A head unit that slept
mid-charge came back and billed the whole gap at the last power reading, and a
session interrupted overnight reported the night as charging time. Reported
duration is metered charging time now, not the span from start to end.
Sessions are metered on DC alone, at or above 10 kW. AC charging on this car is
an overnight affair the head unit sleeps through, so its curve, duration and
energy were guesses either way. The charging screen says so rather than letting
the previous DC session's figures be read as the current AC charge.
Also:
- A daily consumption record uploaded after an offline spell carries the
lifetime total as it stood at the close of that day. Every backlogged day used
to be stamped with the current lifetime, which plots as a flat line and one
cliff.
- The offline session queue is capped at 50. It is a single SharedPreferences
string read into memory in full, and nothing drained it while the cloud
endpoint was unconfigured.
- A long charge keeps the start of its curve: at 720 points the sample interval
doubles and the curve is thinned, rather than dropping the oldest point.
- The cloud sync throttle runs on the monotonic clock, and catch-up sends up to
10 days and 10 sessions per cycle rather than one and three.
