Provenance: Spec 0007 — Victoria Metrics Metrics Stack

Spec: .sdd/specification/spec-0007-victoria-metrics.md Executed: 2026-03-05 Agent: Cursor (claude-4.6-opus)

Actions Taken

1. Read .sdd/specification/spec-0007-victoria-metrics.md for full implementation requirements
2. Read k8s/observability/helmrelease-grafana.yaml for current Grafana datasource configuration
3. Read .sdd/provenance/template.md for provenance record format
4. Created k8s/observability/helmrepository-victoriametrics.yaml — Flux HelmRepository pointing at https://victoriametrics.github.io/helm-charts/
5. Created k8s/observability/helmrelease-victoria-metrics.yaml — HelmRelease for victoria-metrics-k8s-stack chart with all values from the spec (VMSingle, VMAgent, node-exporter, kube-state-metrics, disabled components, K3s-specific overrides)
6. Modified k8s/observability/helmrelease-grafana.yaml — added VictoriaMetrics as a second datasource (type prometheus, URL http://vmsingle-vm.observability.svc.cluster.local:8428, isDefault: false) alongside existing Loki datasource
7. Ran pnpm lint — passed (0 errors, 2 pre-existing warnings unrelated to this spec)
8. Created .sdd/provenance/spec-0007-victoria-metrics.provenance.md (this file)

Decisions Made
