The Model
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:--branch, if provided- the current git branch, if available
mainas a fallback in some flows
Stickiness
deployment.production.areTasksSticky and deployment.preview.areTasksSticky control what happens to running tasks when a new version activates.
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.
