+# Scaleway bootstrap API key
+
+Date: 2026-08-14  
+Catalog: `scaleway-bootstrap` (status `draft`)  
+Owner: `railiance-platform` (CCR-2026-0011) · consumer: `reef-storage`  
+Plan: `ops-mason/plans/reef-storage-scaleway-bootstrap.md`
+
+Org/project API key used only to create the WP-0002 backup bucket.
+Not the Barman runtime key.
+
+## OpenBao pointers
+
+| Field | Value |
+| --- | --- |
+| Mount | `platform` |
+| Path | `platform/workloads/railiance/scaleway/bootstrap` |
+| Fields | `ACCESS_KEY`, `SECRET_KEY`, `DEFAULT_ORGANIZATION_ID`, `DEFAULT_PROJECT_ID` |
+| Terraform map | `access_key`, `secret_key`, `organization_id`, `project_id` |
+
+## Worker checklist
+
+1. Confirm metadata exists (no values):  
+   `bao kv metadata get platform/workloads/railiance/scaleway/bootstrap`
+2. Create the bucket with  
+   `reef-storage/tools/create-platform-audit-bucket.sh`  
+   (reads OpenBao, never prints keys).
+3. Commit only non-secret YAML under `reef-storage/substrate/object-stores/`.
+4. After T04 scoped key works, ask the founder to revoke this bootstrap key.
+
+## Founder provision
+
+Preferred: four paste-once desk writes (one field each), or one local ingest
+of an existing `scaleway.auto.tfvars` — see the mason plan. Never paste
+values into chat.
