HttpUserEngineClient uses trusted-proxy claims against live user-engine. Offline stub when URL/secret unset. Align default tenant with KeyCape tenant:coulomb; map OIDC tenant/principal_type/groups into the envelope.

# user-engine application binding
|
|
|
|
| Field | Value |
|
|
|-------|--------|
|
|
| application id | `coulomb-social` (`USER_ENGINE_APPLICATION_ID`) |
|
|
| display name | coulomb.social |
|
|
| tenant (v1) | `tenant:coulomb` (KeyCape default; Binky friendly slug later) |
|
|
| identity link | `(issuer, sub)` via user-engine `GET /api/v1/me` auto-provision |
|
|
| local row | `members.Member` (no passwords) |
|
|
| live base URL | `https://users.92-205-62-239.nip.io` (cluster ingress) |
|
|
|
|
## Runtime
|
|
|
|
| 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.
|
|
|
|
### Operator: enable HTTP mode locally
|
|
|
|
```bash
|
|
# secret never printed to shell history if you use process substitution carefully
|
|
export USER_ENGINE_BASE_URL=https://users.92-205-62-239.nip.io
|
|
export USER_ENGINE_PROXY_SECRET="$(kubectl -n user-engine get secret user-engine-runtime \
|
|
-o jsonpath='{.data.proxy-secret}' | base64 -d)"
|
|
export USER_ENGINE_EXPECTED_AUDIENCE=user-engine-portal
|
|
# then OIDC or dev-login
|
|
```
|
|
|
|
OpenBao lane for the proxy secret (future): document under railiance-platform
|
|
workload KV; until then kubectl-sourced secret is operator-only on the workstation.
|
|
|
|
## Profile attributes (shell only)
|
|
|
|
- display name (OIDC `name` / user-engine user.display_name)
|
|
- email (optional)
|
|
|
|
Bubble content fields are **not** part of this binding.
|
|
|
|
## Live probe (2026-08-09)
|
|
|
|
`GET /api/v1/me` with probe claims returned `user_id` `usr_…` and
|
|
`actor.tenant=tenant:coulomb` (HTTP 200).
