## Definitions

### `chat.yakka.ban`

**Type**: `record`

A member is barred from a server. Authority-written (ADR 0006). Enforcement is layered (ADR 0008): the mint refuses new credentials immediately and the realtime tier cuts the socket at once, but credentials already held live out their 2h TTL — the protocol has no revocation (Law 2). A ban is therefore effective within the TTL everywhere, and instantly where we serve.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `reason` | `string` | No | Moderator-facing note. Service-observed, never cryptographic evidence — commits are deniable (Law 5, ADR 0009). |
| `subject` | `string` (did) | Yes |  |
| `createdAt` | `string` (datetime) | Yes |  |
| `expiresAt` | `string` (datetime) | No | When the ban lapses. Absent means indefinite. |
