network.machine.paired v1 (OpenVibe.Network, plan L34: the machines hub). A machine was paired with a person's account: it redeemed the one-time code and became theirs. It holds a credential from then on; the code is spent. The machine's device id in Bot is absent until the machine checks in for the first time. Envelope: subject { type: machine, id: <lnk\_…> }, visibility internal, actor service:network.

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `machine_id` | string |  | The machine's device id in Bot's registry, when Bot already knows the device. | - `pattern ^dev_[0-9A-HJKMNP-TV-Z]{26}$` |
| `node_id` | string |  | The machine's node id (platform\_node\_principals.node\_id). | - `pattern ^n-[a-z0-9]{26}$` |
| `principal_id` | string | yes | The node principal the pairing created. Also the envelope subject id. | - `pattern ^lnk_[0-9A-HJKMNP-TV-Z]{26}$` |
| `owner` | string | yes | The person the machine belongs to. | - `pattern ^usr_[0-9A-HJKMNP-TV-Z]{26}$` |
| `at` | string | yes |  | - `format date-time` |
