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/. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Host metrics for falken (the observability host), as in the Ansible stack's

# node-exporter (pid: host, / mounted at /host). hostNetwork so network stats
|
|
# are the host's, not the pod's. Port 9100 on the host is blocked from the

|
# internet by falken's ufw; Prometheus reaches it through the Service.

# This does NOT watch czy, where Ledgerline runs.
