| `unsent_at` (optional)    | string or null | When the sender unsent the message, or null. An unsent Message keeps its place in the transcript and carries no parts.              |
| `deliveries` (optional)   | array          | Per-recipient Delivered and Read truth for direct and group Chats. Relay derives this because it controls every recipient endpoint. |

`edited_at` and `unsent_at` carry a time only on messages from before message editing and unsending were retired. On every message since, both are `null`.
