# Deployments

> Branches, environments, versions, and rollback

Terminal Use deploys agents through branches, environments, and versions.

## The Model

| Primitive     | Meaning                                                     |
| ------------- | ----------------------------------------------------------- |
| `Environment` | A named deployment policy such as `production` or `preview` |
| `Branch`      | A git branch deployment slot                                |
| `Version`     | One concrete deployable build of your agent                 |

Each deploy creates a new version. A branch points at the currently active version for that branch.

## Environment Resolution

The CLI resolves the effective branch from:

1. `--branch`, if provided
2. the current git branch, if available
3. `main` as a fallback in some flows

That branch is then resolved to an environment by branch rules. For a default setup:

| Branch          | Environment  |
| --------------- | ------------ |
| `main`          | `production` |
| everything else | `preview`    |

## Stickiness

`deployment.production.areTasksSticky` and `deployment.preview.areTasksSticky` control what happens to running tasks when a new version activates.

| Setting | Behavior                                     |
| ------- | -------------------------------------------- |
| `true`  | Existing tasks stay on their current version |
| `false` | Existing tasks can migrate during rollout    |

## Rollback

`tu rollback` rolls a branch back to an earlier version.

Rollback uses the target version's `secrets_snapshot`. Pending environment-secret changes are not rewritten by the rollback itself.

## The Main Operational Commands

* `tu deploy`
* `tu ls`
* `tu rollback`
* `tu logs`
