Without an explicit service_name, Loki derived it from the container
label (ledgerline-sanctions-1), while spans carry service.name
"sanctions". Grafana's Tempo->Loki link selects on
{service_name="<service.name>"}, so it matched no stream. The czy agent
now sets service_name from com.docker.compose.service; `container` is
unchanged. CLAUDE.md's description of the labels is updated to match.

k8s/ is now a faithful port of the mentor's Ansible Grafana stack
(Prometheus, Alertmanager, Loki, Tempo, Alloy, Grafana, node-exporter)
for the ledgerline-observability namespace on falken: same versions and
configs, one *.vione.cloud ingress per tool behind Traefik basic auth,
secrets generated by create-secrets.sh into gitignored files.
Two fixes over the Ansible role, both verified live: Tempo's
metrics-generator needs traces_storage or it runs no processors, and
Prometheus needs exemplar-storage to keep exemplars.
Ledgerline stays on czy; an Alloy agent in the Traefik override ships
its container logs to Loki. Roadmap and CLAUDE.md now point at k8s/.
