Date: 2026-08-14  
Status: **applied — Secret `databases/platform-pg-backup-s3` synced**  
CCR: approved in chat 2026-08-14  
Path: `platform/workloads/railiance/backup/object-storage` (KV v2 version 1)

No secret values in this file.

## What is in OpenBao

| Field | Present |
| --- | --- |
| `ACCESS_KEY` | yes (len 20, `SCW…`) |
| `SECRET_KEY` | yes |
| `DEFAULT_ORGANIZATION_ID` | yes |
| `DEFAULT_PROJECT_ID` | yes |
| `APPLICATION_ID` | yes as of version 2 (UUID, not printed here) |

Distinct from the CCR-2026-0011 bootstrap key (`keys_differ=yes`).

## Positive

- `scw object bucket list` / `get railiance-platform-pg-backup` in `nl-ams` succeeded.
- boto3 put/get/delete of a probe object under `platform-pg/` succeeded; probe deleted.
- Sibling prefix write is now denied (`AccessDenied`) after the
  `resource-control-scoped-backup` bucket policy
  (`BackupListPrefix`, `BackupObjectsUnderPrefix`) applied 2026-08-14.

## Negative

- Bogus secret against the same access key: `SignatureDoesNotMatch`.
- `scw iam application list` / `user list` / `api-key get`: insufficient permissions.
- `scw billing budget list`: not allowed.
- `scw k8s cluster list`: insufficient permissions.

`instance` / `vpc` / `rdb` / `registry` / `lb` list returned empty success. That is consistent with a project that has no those resources; it is not a proven compute-write deny. Do not create a paid resource to prove it.

## Cluster delivery (same day)

- Policy `workload-kv-read-backup-object-storage` written.
- AppRole `external-secrets-backup-object-storage` (15m/30m, 8 uses).
- Secret `external-secrets/openbao-backup-object-storage-approle` applied; local delivery shredded.
- ClusterSecretStore `openbao-backup-object-storage` Ready/Valid, condition `databases` only.
- ExternalSecret `databases/platform-pg-backup-s3` SecretSynced. Keys `ACCESS_KEY_ID` (len 20) and `ACCESS_SECRET_KEY` (len 36). Values not read.
- Prefix `platform-pg/` object count: 0.
- `platform-pg` still has no `barmanObjectStore`. WAL is T05.
