| Field | Value |
|

|

|
|
| application id | `coulomb-social` (`USER_ENGINE_APPLICATION_ID`) |

|
|
|
| tenant (v1) | `tenant:coulomb` (KeyCape default; Binky friendly slug later) |
|
|
|
|
|

## Runtime
|
|
|
|
|
|
2026-08-09 01:56:44 +02:00
|
|
|
| Mode | When | Behavior |
|
|
|
|
|
|------|------|----------|
|
|
|
|
|
| **stub** | `USER_ENGINE_BASE_URL` or `USER_ENGINE_PROXY_SECRET` empty | Deterministic `user_id` from sha256(iss\|sub) |
|
|
|
|
|
| **http** | both set | Trusted-proxy `GET /api/v1/me` with IAM-shaped claims envelope |
|
|
|
|
|
|
|
|
|
|
### Trusted proxy envelope
|
|
|
|
|
|
|
|
|
|
user-engine accepts claims only when:
|
|
|
|
|
|
|
|
|
|
```http
|
|
|
|
|
X-User-Engine-Proxy-Secret: <secret from user-engine-runtime>
|
|
|
|
|
X-Verified-Oidc-Claims: {"iss","sub","tenant","principal_type","aud",...}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
`aud` must include the portal audience `user-engine-portal` (deployed expectation)
|
|
|
|
|
plus `coulomb-social`. Trust is the proxy secret; claims were verified by
|
|
|
|
|
KeyCape OIDC at the app edge.
|

### Governed credential configuration

|
|
|
Live HTTP mode already uses mounted runtime credential references. Do not
|
|
|
|
|
extract the proxy secret with kubectl/jsonpath or print it into shell/chat.
|
|
|
|
|
For a new credential need, run `warden route find "user-engine trusted proxy credential" --json`
|
|
|
|
|
and follow the owning OpenBao/platform lane. Interactive personal login belongs
|
|
|
|
|
to KeyCape/NetKingdom; it does not require retrieving this server credential.

## Live probe (2026-08-09)
|
|
|
|
|
|
|
|
|
|
`GET /api/v1/me` with probe claims returned `user_id` `usr_…` and
|
|
|
|
|
`actor.tenant=tenant:coulomb` (HTTP 200).
