# GitMachine `git.machine@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

- Version: 1.0.0
- Owner: git
- Visibility: public
- Status: active
- Compatibility: backward
- Schema: [`https://openvibe.network/contracts/git/machine.v1.json`](/docs/contracts/git.machine.json)

A computer published to OpenVibe.Git through Link, read-only. Link connects out to Git, sends its name and the repositories under the root the person chose in Link, and keeps watching: the page lists the machine and browses its tree, files and log through Link while it is online. The request never reaches the machine; Git only asks on a poll the machine opened. Nothing here is a write path.

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `id` | string | yes | The machine's own id (mch\_<ULID>), minted by Git when the person connects it. | - `pattern ^mch_[0-9A-HJKMNP-TV-Z]{26}$` |
| `name` | string | yes | The computer's name, as Link knows it. | - `minLength 1`<br>- `maxLength 80` |
| `os` | string |  | linux, darwin or windows, for the page's small label. | - `maxLength 40` |
| `online` | boolean | yes | True when Link has checked in within the last thirty seconds. |  |
| `last_seen_at` | string | yes |  | - `format date-time` |
| `offline_since` | string \| null |  | When the machine was last seen before going offline; null while it is online. | - `format date-time` |
| `repos` | array of object | yes |  | - `maxItems 500`<br>- `items: no other fields` |
| `repos[].name` | string | yes | The folder's name, lower-case, the same rule as a Git repository name. | - `pattern ^[a-z0-9][a-z0-9._-]*$`<br>- `maxLength 100` |
| `repos[].branch` | string | yes | The branch checked out in that folder. | - `maxLength 255` |
| `repos[].head` | string | yes | The commit's full SHA (SHA-1, or SHA-256 when the repository uses it). | - `pattern ^[0-9a-f]{40}(?:[0-9a-f]{24})?$` |
| `repos[].head_subject` | string |  |  | - `maxLength 200` |
| `repos[].updated_at` | string |  | The commit's own date. | - `format date-time` |
