- "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.
