  disposition: storage backup restore and rollback policy

  summary: >-
    Loki's default chart cannot render until storage bucket and schema values
    are supplied. The supported bases make storage explicit:
    single-binary-filesystem uses filesystem storage and one Loki StatefulSet
    for the simple proof path, while simple-scalable-minio uses S3-compatible
    storage with a chart-owned MinIO fixture. This disposition accepts those
    storage choices as production review input, not as a final production
    retention, backup, restore, or rollback policy.
  evidence:
    - path: recipes/grafana/loki/7.0.0/default-render-blocker.yaml
      claim: The default Helm render is blocked until storage bucket and schema values are selected.
    - path: recipes/grafana/loki/7.0.0/value-model.yaml
      claim: The value model records schemaConfig, filesystem storage, S3 bucket names, MinIO dependency enablement, and dependency locks explicitly.
    - path: recipes/grafana/loki/7.0.0/effective-values.yaml
      claim: The single-binary-filesystem base binds SingleBinary topology, filesystem storage, replication factor, and schema epoch.
    - path: recipes/grafana/loki/7.0.0/effective-values-simple-scalable-minio.yaml
      claim: The simple-scalable-minio base binds S3-compatible storage, bucket names, MinIO endpoint, and the chart-owned MinIO fixture.
    - path: recipes/grafana/loki/7.0.0/revisions/single-binary-filesystem/r001/rendered/object-inventory.yaml
      claim: The single-binary-filesystem inventory records Loki, chunks-cache, and results-cache StatefulSets.
    - path: recipes/grafana/loki/7.0.0/revisions/simple-scalable-minio/r001/rendered/object-inventory.yaml
      claim: The simple-scalable-minio inventory records Loki backend/write/cache StatefulSets and the MinIO StatefulSet and Secret.
    - path: recipes/grafana/loki/7.0.0/revisions/single-binary-filesystem/r001/receipts/scan-receipt.yaml
      claim: The single-binary-filesystem scan records storage config and StatefulSet review findings.
    - path: recipes/grafana/loki/7.0.0/revisions/simple-scalable-minio/r001/receipts/scan-receipt.yaml
      claim: The simple-scalable-minio scan records object-store, MinIO Secret ownership, and StatefulSet review findings.
    - path: runs/live-helm-confighub-compare/grafana-loki-single-binary-filesystem/receipt.yaml
      claim: The simple base has passing regular Helm, ConfigHub kubectl apply, and ConfigHub OCI/Argo live parity.
    - path: runs/live-kind-parity/grafana-loki-simple-scalable-minio/receipt.yaml
      claim: The MinIO scalable base has semantic parity but runtime remains target-resource sensitive in small kind.
  affectedVariants:
    - single-binary-filesystem
    - simple-scalable-minio
  acceptedPolicy:
    singleBinaryFilesystem: Accepted as the first local-test and production-review path; production retention and backup remain target decisions.
    simpleScalableMinio: Accepted as a local object-store fixture and review input; production should normally choose a real object-store target and credential policy.
    rollback: Storage rollback cannot be inferred from render parity and must be recorded as an operating procedure for the selected storage backend.
  variantCaveats:
    - "simple-scalable-minio is not the easiest production path; its current live parity row is runtime-blocked/watch because replicas exceed the small kind target capacity."
    - "MinIO Secret material is test fixture material; production object-store credentials should be target facts or a managed secret reference."
  remainingProductionBlockers: []
  nextDecision: A production support decision should select the Loki storage backend, retention period, backup/restore method, rollback procedure, and target runtime capacity.
