Fired on insert of a new room task. The payload is the full task, identical to the object returned by `GET /api/v1/agent/chats/{chat_id}/tasks/{id}`.

## When It Fires

* A task is created on the chat room's board via `POST /api/v1/agent/chats/{chat_id}/tasks`.

## What to Do

1. Add the task to your local board, keyed on `id`.
2. Render its assignments and status.

Task UUID.

---

**`chat_room_id`** `uuid` — required

UUID of the chat room the task belongs to.

---

**`number`** `integer` — required

Sequential per-room task number.

---

**`subject`** `string` — required

Short task title.

---

**`detail`** `string` — required

Longer description. Empty string `""` when unset, never null.

---

**`overall_status`** `string` — required

---

**`updated_at`** `datetime` — required
