The tiles, bar charts and route map were already MG red; the line
charts still used Grafana's default palette. Now the first line of a
pair is MG red (#E0424C) and the second light red (#FF9A9E), as in
the app; the tyre chart adds deep (#A8323A) and pale (#FFD0D2) red.
Covers SoC/range, power/speed, voltage/current, tyre pressures and the
charging curve. Checked by rendering the Live and Charging dashboards.

The car publishes no battery, cabin or outside temperature and no pack
energy (checked against the fields that reached InfluxDB). Instead of
panels that stay empty:
- Battery temperature tile -> Climate setpoint.
- Outside temperature tile -> Last update ("2 minutes ago").
- Energy in pack = SOC x usable capacity, from the hidden dashboard
constant usableKwh = 50.8 (51 kWh battery).
- Temperatures chart -> Battery voltage and current.
Checked with a simulated drive carrying exactly the car's fields: all
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.

It runs at about 406 MiB in the cluster, too close to the 512Mi limit:
long-range dashboard queries could get it OOM-killed. The request now
matches what it uses, so the scheduler reserves it.

Grafana's first start creates and migrates its database: 44 s at
0.5 CPU and 3 minutes at 0.1 CPU (measured with 13.2.3 on an empty
volume). With only 50m requested, the liveness probe (30 s delay,
3 x 30 s) restarted it mid-migration, in a loop, and readiness never
passed.
- startupProbe on /api/health allows up to 10 minutes; liveness and
readiness start only after it succeeds.
- 5 s timeouts on all probes instead of the 1 s default.
- Requests raised to 250m CPU / 256Mi (measured about 240 MB in use);
still no CPU limit.

- 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).

- On a failure the pairing dialog stays open and shows the reason in
red (Cancel becomes Close); before, it closed at once and the reason
was only in the Server tab's status line.
- "Pairing is not enabled" only when the server says so. Any other 404
(a server older than 2.1.0, or a proxy's page) is reported as a
server without pairing.
- Pairing and Test connection name the problem: a server name that
does not resolve (Test connection used to say "No internet
connection"), a server that does not answer, or the HTTP status.

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.

The server's host is car.k8s.stinnesbeck.com, not car.stinnesbeck.com:
IngressRoute, PUBLIC_URL (so the pairing QR code points there), the
app's pre-filled server URL and hint, and the docs. Grafana's
placeholder host follows to car-grafana.k8s.stinnesbeck.com, so one
*.k8s.stinnesbeck.com default certificate covers both. App 2.4.1 for the
new default; the server image is unchanged (its URL comes from the
manifest).

- kustomization pins mg4-server 2.1.0 by digest; server.yaml sets
PUBLIC_URL for the pairing QR code; the secrets template gains
APPROVAL_PASSWORD.
- Filled-in Secrets now go into k8s/secrets.yaml, which is gitignored;
the template stays on placeholders. This follows a leak where real
values typed into the template were committed and pushed (amended and
force-pushed since; both values regenerated).
- SPECS.md records pairing and the incident.

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.

- 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.

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.

Browser title, login heading, hidden password-manager username, session
cookie (nilsmg4_session) and package name. The README keeps the credit
to fatihdonmezdev/FatihsMG4. Server version 1.1.1; the manifests pin it.

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.
