## Definitions

### `social.smallbury.feed.reaction`

**Type**: `record`

Emoji reaction by an actor on a post or comment. Use one record per emoji (stacking supported). Public targets store cleartext emoji. Reactions to encrypted targets store ciphertext plus keyEpochId.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `emoji` | `string` | No | Cleartext emoji reaction for public targets. Omit when ciphertext is set. |
| `subject` | `ref` → `com.atproto.repo.strongRef` | Yes | AT-URI/CID of the target post or comment. |
| `createdAt` | `string` (datetime) | Yes | Client-declared timestamp when this reaction record was created. |
| `ciphertext` | `bytes` | No | Encrypted reaction payload for private targets. Omit for public targets. |
| `keyEpochId` | `string` | No | Trust key epoch used for encrypted reactions. Required when ciphertext is set. |
