| Active branch | The branch selected in the project tree; all element operations use it. Shown with the Active tag. |
| Baseline | Version of an element a branch started from (parent’s version at creation or after the last rebase). Common ancestor for three-way comparison. |
| Branch | Named, independently evolving copy of the metadata model inside one system. |
| Branch status | Active (Opened), Locked, Archived, Deleted. |
| Branch tree | Hierarchy of branches on the Branches page. |
| Cherry-pick | Copy selected elements from another branch into the current branch as new versions. |
| Compare | List of elements changed between two branches with field-level diff. |
| Confidential branch | Branch with restrict to explicit permissions; currently enforced only for cherry-pick sources. |
| Conflict | Same field changed differently on both branches since the baseline. |
| Deployment package | Set of elements with pinned versions for script generation and deployment; belongs to one branch. |
| Main branch | The main branch of a system; cannot be renamed or deleted. |
| Merge | Applying an approved merge request to the target branch. |
| Merge event | Audit record of an executed merge. |
| Merge lock | Lock on the target branch held while a merge runs, when require explicit merge action is set. |
| Merge request (MR) | Reviewable proposal to merge a source branch into a target branch. |
| Minimum number of approvers | System parameter (0–10, default 0); lower bound for required approvals of new or edited branches. |
| Own version | Latest version of an element pushed on the branch itself. |
| Opened | UI label of the Active status; also the default tree filter (Active + Locked). |
| Protected branch | Branch that accepts changes only through merge requests. |
| Quorum | Number of approvals needed: the target branch’s Required approvals. |
| Rebase from parent | Move a branch’s baselines to the parent’s current state while keeping own changes. |
| Required approvals | Approvals needed for merge requests into the branch; 0 approves conflict-free MRs immediately. |
| Self-approval | Whether the MR author may approve their own MR. |
| Source branch | Parent of a branch; also the branch that brings changes in an MR or cherry-pick. |
| Stale | MR status meaning the diff is outdated and approvals must be collected again. |
| Version label | {branch-name}-{number}, for example main-12. |
| Working data | Edit draft of an element, stored per branch. |
