## Definitions

### `at.turtleme.chat.message`

**Type**: `record`

A single message sent to a turtle meat chat room. Messages live in the author's own repository; a room is assembled by reading the backlinks that point at it.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `createdAt` | `string` (datetime) | Yes | Timestamp declared by the sending client. It is not verified, so readers that care about ordering should prefer the record key. |
| `facets` | `array` | No | Rich text over byte ranges of 'text', in Bluesky's facet shape. turtle meat writes and reads only mentions (app.bsky.richtext.facet#mention), each pointing at the DID the handle in the text meant when the line was sent. There is no threading: a mention points at an account, not at a message. Byte offsets count the whole of 'text', colour and effect codes included. |
| `room` | `string` (uri) | Yes | The room the message was sent to. 'https://turtleme.at/chat/global' is the global room. Because this is a link, a backlink index can list a room's messages without a dedicated AppView. A message written into a clan, an at.turtleme.chat.clan permissioned space, carries that space's at:// URI here instead; it lives in the author's permissioned repository for the space rather than their public one. |
| `text` | `string` | Yes | The message body. It may carry Old School RuneScape style chat codes in the form 'colour:effect:message', for example 'red:wave:hello there'. A client that does not recognise the codes should display the string verbatim rather than stripping it. |
