## Definitions

### `chat.yakka.channel.info`

**Type**: `record`

A channel's presentation and its gate. Authority-written into the directory space via the space host (ADR 0006). The gate here is the same policy the mint enforces (ADR 0007) — an open and a gated channel are structurally identical spaces, so toggling `allowedRoles` is a policy edit and never a data migration (ADR 0002).

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `kind` | `string` | Yes |  |
| `name` | `string` | Yes |  |
| `group` | `string` | No | Sidebar grouping label. Purely presentational. |
| `topic` | `string` | No |  |
| `createdAt` | `string` (datetime) | Yes |  |
| `allowedRoles` | `array` | No | Roles whose holders may be minted a credential for this channel. Absent or empty means any member of the server — which is what an 'open' channel is. Presence of this field is the only difference between an open channel and a gated one. |
