## Definitions

### `blue.catbird.circle.metadata`

**Type**: `record`

Circle metadata, authored by the Space authority into its own permissioned repo. The only Catbird-specific record type in a Circle; posts and likes are unmodified Bluesky records.

**Key**: `literal:self`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `name` | `string` | Yes |  |
| `circleId` | `string` (tid) | Yes | Stable Circle identity, independent of the Space key. Survives migration to a different Space, which is the only identifier that does. |
| `createdAt` | `string` (datetime) | Yes |  |
| `migratedTo` | `string` (space-ref) | No | The Space this Circle's content was migrated to, if any. Set when the Circle has moved and this Space is retained read-only. |
| `migratedFrom` | `string` (space-ref) | No | The Space this Circle's content was migrated from, if any. |
