tegwick 34a014a896 feat: inventory schema 0.3 and close WP-0006 T01 T02 T04
v0.2 records stay valid. v0.3 requires the five facets. Validators
reject inline Scaleway endpoints and secret-looking strings. The
backup record is the first 0.3 object. Reef views already met T02.

# Operational reference convention v0.1
Status: baseline
Effective: 2026-08-14
Owners: `resource-control` (join keys), `reef-*` (operational facts)
`resource-control` manages resources from **procurement, consumption, usage,
and cost**. It does not operate them. A `reef-*` repo is the operational
substrate. Non-secret operating attributes and credential *handles* are
therefore **references**, never copies of the operating record and never
secret values.
This is the join convention. Schema adoption is `RESOURCE-WP-0006`.
`reef-storage` materialization is `RMASTER-WP-0022`.
---
## Authority
| Fact | Authoritative home |
| --- | --- |
| Why the resource exists, what was decided, who pays, who may consume, what it cost | `resource-control` |
| How the substrate is named, reached, bound, and run | the `reef-*` repo |
| Secret material (access keys, tokens, payment instruments) | approved OpenBao / credential-broker lane (`railiance-platform` today) |
| Booked invoices and recognized payments | `fin-hub` |
| Workload use of a reviewed destination | the consuming `rapp-*` |
Do not duplicate a reef attribute into the inventory record “for convenience.”
Cite it. If the reef path moves, update the reference, not a shadow copy.
---
## Reference forms
### Reef attribute
A non-secret operating fact owned by a reef:
```text
reef:<reef_id>/<repo-relative-path>#<json_or_yaml_key>
```
- `reef_id` equals the reef repo slug (`reef-railiance`, `reef-storage`).
- Path is from the reef repo root, POSIX, no `..`.
- Fragment is a dotted key into that file (`endpoint`, `bucket.prefix`).
- The file is committed, non-secret, and the reef is authoritative for it.
Examples (live on `reef-storage` and `reef-railiance`):
```text
reef:storage/substrate/object-stores/platform-audit-storage.yaml#endpoint
reef:storage/substrate/object-stores/platform-audit-storage.yaml#bucket
reef:storage/substrate/object-stores/platform-audit-storage.yaml#region
reef:railiance/declarations/reef.yaml#current_members
```
Inventory stores the reference, not the endpoint string.
### Credential handle
A pointer to custody, never a value:
```text
secret:<custody_repo>/<secret_id>
```
Example already named by the backup split:
```text
secret:railiance-platform/backup
```
The handle may also record `broker` (`openbao`) and `rotation` as non-secret
metadata. The secret body stays in the broker.
### Structured form
When a record needs more than a string:
```json
{
"kind": "reef_attribute",
"reef_id": "reef-storage",
"repo": "reef-storage",
"path": "substrate/object-stores/platform-audit-storage.yaml",
"key": "endpoint",
"ref": "reef:storage/substrate/object-stores/platform-audit-storage.yaml#endpoint"
}
```
```json
{
"kind": "credential_handle",
"custody_repo": "railiance-platform",
"secret_id": "backup",
"broker": "openbao",
"ref": "secret:railiance-platform/backup"
}
```
Both `ref` and the parsed fields must agree when both are present.

## What a resource-control resource then holds
Five facets, all first-class in the forthcoming inventory v0.3:
1. **Description** — purpose and class; why this resource exists.
2. **Decision** — chosen option, approver, date, rejected alternatives
(or an explicit “not decided” gap). Required before status `ordered`.
3. **Operational attribute refs**`reef:…` pointers. Empty only with an
explicit gap (reef not created yet).
4. **Credential handles**`secret:…` pointers. Empty is allowed when no
credential exists yet; values are never stored here.
5. **Consumers**`potential` (intended / declared) vs `actual` (observed
using the resource). A name in `workload_ids` alone is not enough.
---
## Reef views
`data/reefs/<reef_id>.json` is the **resource-control view** of a reef: which
inventory records implement its procured capacity, which entities pay, which
consumers are potential vs actual. It is not a second `reef.yaml` and must
not restate member IPs, kubeconfig paths, or endpoints.
`reef-railiance` is compute (Host Europe `railiance01`, k3s, platform
services). It does **not** grow an S3 object store. Backup object storage is
a different substrate boundary: `reef-storage`.
---
## Backup / S3 split (the proving case)
| Concern | Owner |
| --- | --- |
| Demand, comparison, purchase approval, cost, settlement | `resource-control` (`RESOURCE-WP-0002`) |
| Operate the Scaleway (or successor) object store: endpoint, bucket, region, lifecycle as committed facts | `reef-storage` (`RMASTER-WP-0022`) |
| Credential custody and delivery | `railiance-platform` OpenBao |
| Barman, schedule, retention, restore | `rapp-postgres` after a reviewed destination |
| Consume the destination | `rapp-postgres` (actual once WAL flows) |
Until `reef-storage` exists, the proposed backup record may cite a gap
instead of a `reef:` URL. That gap is expected; inventing an endpoint here
is not.
