nodes, pods, PVCs, PVs, storageclasses, metrics.k8s.io) and Prometheus, reuses
build_observation / reconcile.join / build_report / retain unchanged, and
retains ISO-week reports, per-attempt inputs and an append-only receipt log.
Telemetry window ends Monday 06:00 UTC so weeks stay comparable across DST.
