## Definitions

### `at.blueharbor.createSession`

**Type**: `procedure`

The lxm named in service-auth JWTs minted for the BlueHarbor backend (aud did:web:blueharbor.at). The backend verifies the JWT against the caller's DID document and exchanges it for a BlueHarbor session token. Defined here so the method identifier resolves; the HTTP call itself is served by the BlueHarbor service, not a PDS.

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `did` | `string` (did) | Yes |  |
| `token` | `string` | Yes |  |
| `expiresAt` | `integer` | Yes |  |
