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.

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).

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.
