+# reef-storage — Agent Instructions
+
+## Repo Identity
+
+**Purpose:** Provider-delegated S3-compatible storage substrate. Owns
+non-secret operating attributes. Does not host a rail.
+
+**Domain:** financials  
+**Repo slug:** reef-storage  
+**Workplan prefix:** `REEF-STORAGE-WP-`
+
+## Standing rules
+
+- No rail. Scaleway (or a successor provider) operates S3.
+- No secrets in this repo. Cite `secret:railiance-platform/<id>`.
+- Attribute files are the source for `reef:storage/…#key` references.
+- Do not fold this substrate into `reef-railiance`.

+# INTENT
+
+## Why This Repo Exists
+
+`reef-storage` is the substrate boundary for **provider-delegated
+S3-compatible object storage**. The first instance is Scaleway, used for
+postgres backup and other large, slow-tolerant volumes.
+
+We consume the S3 capability. We do **not** host a rail and we do **not**
+operate how Scaleway provides or runs object storage. This reef names the
+boundary, holds the committed non-secret attributes, and is the place
+operators look for “where is our object store?”
+
+It is a different reef from `reef-railiance`. Backup is not bolted onto
+the home compute substrate.
+
+## What This Repo Must Protect
+
+- the split: procure/cost in `resource-control`, operate-by-reference here,
+  secrets in `railiance-platform`, consume in `rapp-*`
+- no rail invented to satisfy a compute-centric schema
+- no secret material in git
+- independent failure domain from Host Europe / `reef-railiance`
+
+## What This Repo Is Not
+
+- a Scaleway account manager or billing ledger
+- a Barman/CNPG operator (`rapp-postgres`)
+- a secret store
+- a generic S3 client library
+- an extension of `reef-railiance`

+# SCOPE
+
+## One-liner
+
+Provider-delegated S3-compatible storage reef: identity and non-secret
+attributes, not a rail, not a secret store.
+
+## In Scope
+
+- Reef declaration (`substrate_kind: object-storage`, no rail)
+- Committed non-secret object-store attributes (endpoint, region, bucket,
+  prefix, versioning/lifecycle flags, provider project ref)
+- Runbooks for “how we use the delegated store,” not how Scaleway runs it
+- Binding notes for consumers (`rapp-postgres` first)
+
+## Out of Scope
+
+- Purchase approval, forecasts, settlement (`resource-control`)
+- Access keys and OpenBao delivery (`railiance-platform`)
+- WAL archive, backup schedule, restore (`rapp-postgres`)
+- Hosting Kubernetes or any rail
+- Implementing S3
+
+## Getting Oriented
+
+- Declaration: `declarations/reef.yaml`
+- Attribute contract: `schemas/object-store-attributes.schema.json`
+- Attribute files: `substrate/object-stores/`
+- Join convention: `resource-control/docs/operational-reference-convention.md`

+## Goal
+
+Stand up the planned storage reef: declaration without a rail, attribute
+file layout, and the contract for non-secret object-store facts.
+
+## T01 — Declare the reef
+
+```task
+id: REEF-STORAGE-WP-0001-T01
+status: done
+priority: high
+```
+
+`declarations/reef.yaml`: `substrate_kind: object-storage`, no
+`primary_rail`, no `hosted_rails`, empty `current_members`, planned.
+
+## T02 — Attribute contract
+
+```task
+id: REEF-STORAGE-WP-0001-T02
+status: done
+priority: high
+```
+
+`schemas/object-store-attributes.schema.json` and a planned
+`platform-audit-storage.yaml` with null operating fields until purchase.
