## Definitions

### `com.cultureblocs.annotation`

**Type**: `record`

A bookmark/note about a specific work, typically minted by the AR gallery app at the moment of recognition. Meaningful entirely on its own — no bead required.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `geo` | `ref` → `com.cultureblocs.defs#geo` | No |  |
| `note` | `string` | No |  |
| `work` | `ref` → `com.cultureblocs.defs#workRef` | Yes |  |
| `media` | `array` | No |  |
| `images` | `array` | No | Published images as imageRefs. Tier 0 records use `media` (local refs); the promoter uploads the bytes and maps alt + aspectRatio across at publish time. |
| `context` | `ref` → `com.cultureblocs.defs#strongRef` | No | Optional exhibition or event record this annotation was made within. |
| `createdAt` | `string` (datetime) | Yes |  |
| `provenance` | `ref` → `com.cultureblocs.defs#provenance` | No |  |
| `matchConfidence` | `string` | No | How the work was identified: cosine embedding match, ORB geometric verification, or manual entry. |
