czy publishes no service ports, so Traefik exposes each service's :9464
as https://ledgerline.vione.cloud/metrics/<service> behind basic auth,
and the platform's Prometheus gets a `ledgerline` job with one target
per service. The targets share an address; a `service` label tells them
apart, and relabels derive __metrics_path__ and instance from it.
create-secrets.sh now also creates the prometheus-scrape-auth secret
(mounted optional, so a missing secret fails only this job) and writes
the gitignored htpasswd file Traefik reads, which is copied to czy like
.env.observability.

Add opentelemetry-distro/exporter-otlp (pinned pair) and run
opentelemetry-bootstrap at build time; wrap the sanctions command with
opentelemetry-instrument and configure the SDK via OTEL_* env (traces
only, OTLP/HTTP to otlp.vione.cloud). create-secrets.sh now writes the
base64 OTLP auth header into .env.observability.
The G10 guard test (no observability libraries in requirements) is
expected to fail from here until the guard suite is retired in Phase 3.

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/.
